Unite BE and MA difference as far as possible fast implement the treatment craft that housing, tine encircles. To BE tine is encircled, a machining center increases to be used at machining installing hole before heat, the product line after heat increases a grinder to be used at inside the grinding of aperture. Poor to BE fast implement housing, increase a machining center to be used at bore, tap and mill chamfer later in fine vehicle. 2.
Redesign and make partial fixture, ungual to the card of manipulator, carry raceway to undertake transforming, reduce tool as far as possible change model. 3.
Redesign and make partial cutting tool, reduce cutting tool as far as possible change model. 4.
The machine program of spare parts of BE of new authorized strength. Transformed crucial BE is poor fast implement housing and the technology design that tine encircles are whole the key that transforms a project, because,this is: 1.
BE and MA are poor fast implement the technology of housing asks to have bigger difference, MA is poor fast implement housing cooperates with what tine encircles is the means that uses gelatinize and press fitting, and BE is poor fast implement of housing and tine circle cooperating is to use means of connective of 8 whorl aperture. 2.
BE is poor fast implement what use outside Kong Zaiguo of housing axle shaft is honing machine treatment, bearing neck and flange face use grinder treatment, and what we use is to bore hole, dry type turning. 3.
BE is poor fast implement housing has 8 whorl opening, the treatment of flange face is interrupted cutting, whether can existing equipment satisfy the treatment quality of flange face, depend on the rationality that craft arranges. The technical content that transforms program 1.
The BE that designs by oneself is poor fast implement the feasibility of housing technology program is analysed (1) MA is poor fast implement housing and BE are poor fast implement the difference of housing (if pursue 1) . From the watch 1 can see, MA and BE are poor fast implement housing figure has bigger difference, and BE is poor fast implement the surface roughness of aperture of housing axle shaft and bearing neck is more severe than the requirement of MA. Graph 1 MA and BE are poor fast implement the exterior difference of housing (2) BE of proper motion design is poor fast implement the comparison of mature technology of housing craft and beautiful company. Graph the BE that the 2 GB that it is a law send a company is poor fast implement the technological process of housing, graph the 3 BE that design independently for us are poor fast implement housing technological process. Graph the BE of beautiful company differs 2 France fast implement the technological process of housing pursues the BE of 3 own designs is poor fast implement the biggest difference of the technology program of abroad of housing technological process and the craft plan that we devise by oneself reflects in 4 place: The treatment of diameter of axle shaft aperture, two upright bearing and flange face. In France, use honing to the treatment of axle shaft aperture, and what to two end the treatment of bearing neck and flange face uses is grinding. The treatment of the aperture of axle shaft of appearance difference ① that graph 4 MA ages circle and BE tine are encircled. BE is poor fast implement the requirement of product of aperture of housing axle shaft is φ 260+0.
033, the requirement of exterior surface roughness is R5, be equivalent to Ra1.
6. MA is poor fast implement the requirement of product of aperture of housing axle shaft is φ 250+0.
033, exterior surface roughness is R6.
3, be equivalent to Ra2, the tolerancepublic errand requirement of bore diameter is basic and same, but with respect to exterior surface roughness character, BE is poor fast implement the requirement of housing is stricter, we analysed the cutting parameter of aperture of MA axle shaft, n=1500r/min, ap=0.
25 Mm/r, change cutting parameter to maintain N and Ap changeless, reduce F. The cutting parameter with our disparate test, final the feed MA by 0.
25mm is reduced 0.
When 18mm, surface roughness of the surface when cutting tool machines life is R4.
5, can satisfy the requirement of surface roughness. Graph the treatment that the BE tine of 5 own designs encircles neck of bearing of technological process ② . The diametical MA of bearing neck and BE are poor fast implement housing is same product demand, all be φ 38+0.
027, but the requirement BE of exterior surface roughness is R5, MA is R6.
3, experiment according to the treatment of half-and-half axis aperture, the requirement of bearing neck can be achieved. Watch 1 MA and BE are poor fast implement housing is main the treatment of the face of difference ③ flange that the technology asks. The BE that treatment takes 8 whorl aperture is poor fast implement housing flange face has two characteristics, it is interrupted cutting, the 2 length that are treatment are as long as 20mm. Existing equipment is lathe of horizontal numerical control, and to do type cutting, then we devised two craft plan: The first is by groovy craft before fine vehicle bore, tap; Program of the 2nd technology is to be after fine vehicle, bore, tap. The MA in graph 6 OP40 and BE are poor fast implement the clamping apparatus design of housing is in the executive process of technology program, we discover equipment of existing fine vehicle cannot satisfy BE to differ fast implement the quality requirement of housing flange face, then we adopt plan of the 2nd craft, move bore, tap and mill chamfer to undertake machining to the OP105 after fine vehicle. After a flight of stairs gets treatment, we discover the entrance of aperture is in existence burr, through delay time order increasing to bore in NC program, the burr of flange face was done not have. Pass analysis and experiment proof, the BE that we design independently is poor fast implement the craft of housing is feasible. 2.
If the difference that the feasibility analysis MA of the plan of craft of BE tine circle that devises by oneself ages circle and BE tine encircle an appearance pursues 4, its are main if the difference that the technology asks is expressed 2. From the watch 2 can see, MA and the technical parameter that BE tine encircles have bigger difference, especially the biggest effective tine carries round diameter on the head, BE compares MA most greatly 29.
7mm, and the diameter is more than 180mm, the tine circle of BE of width of core axis fixed position and MA is compared narrow 15.
4mm, the craft sex that so BE tine encircles ages than MA the circle is differred. Graph 7 OP70 is poor fast implement if pursue,the BE tine that the clamping apparatus of housing designs us independently encircles technological process 5. The biggest difference of technology program of abroad and the craft plan that we devise by oneself depends on: Bore ＋ two sides pours wine cup, french arrangement is in OP30, before gear hobbing, and our plan is arrangement in OP70, after shave ages. Because we are the transforms a future life to produce BE tine groups that pass pair of old lines, did not put the space of equipment between lathe and gear hobbing, can put after shave ages only. The experiment proves: Below the premise that flows in convenient spot content, the technology program that we plan can make sure the quality of the product asks completely, it is completely feasible. 3.
Poor fast implement of housing product line and tine group product line transform (1) technology design: ① adopted a plan 3 with the graph 5 in the BE of own design is poor fast implement housing and the craft that BE tine encircles. The work out of program of ② CNC Machining and debug: Poor to BE fast implement the work out that housing and tine of two kinds of BE encircle the spare parts of each working procedure to have NC program, involved system has FANUC, NUM and Siemens3 to plant; Involve numerical control machine tool 12, come from Japan, France and Germany respectively. (2) clamping apparatus designs ① OP40, differ through if the graph shows MA and BE 6 times,be being designed fast implement the V with common housing piece 1, 2, pressing plate 8 with V model pressure piece 5 will come true change model hind, clamping apparatus precision need not be adjusted. Only through changing axial locates piece 3, outline bearing 4 with impaction board 6, will satisfy the MA with dimension of two kinds of axial, height dimension and outline bigger difference and BE to differ fast implement the fixed position of housing and clamp. Graph 8 013 is versed in, rough machining is spherical ② OP70 is poor fast implement the crucial working procedure that housing machines, the design of this clamping apparatus adopts the distributinging plan of high concentration, so that put apart is enough space, make 6 direction can decorate clamping apparatus well, what this equipment uses is the fixture that German ROHM company designs. Original design only the MA of 77 differs applicable S φ fast implement housing, and the BE of 84 differs S φ fast implement housing ply is bigger than its 12mm, cannot use, because the function of domestic coordinate grinder is restricted, this fixture is made without legal system in home. We pass the three-dimensional imitate, clamping apparatus that redesigns OP70, undertake transforming on the foundation of German ROHM clamping apparatus, will be like the clamping apparatus that the graph shows 7 times to secure seat the ply of 1 reduces 12mm, the oriented lever clamping apparatus 2 lengthen 12mm, redesign create oriented staff 2, clamp card is ungual 3, slide block 4, fixed position piece 5 with clamp piece 6. (3) the cutting tool design of OP40 of ① of cutting tool design: OP40 is a 3 labour numerical control modular machine tool, be versed in for 011/012/013 respectively. 013 labour it is spherical working station, the structure that cutting tool uses is brace linkage mechanism, when the whirl on arbor the point drops after the position of ball heart, the brace linkage mechanism that drives cutting tool through electric machinery of machine tool servo moves, finish spherical rough machining (if pursue 8) . The common cutter hub that if the graph is shown 9 times,we redesigned, simplified to change model, different knife changes to place only between different breed can. Graph 9 those who redesign is common the cutting tool design of OP70 of cutter hub ② : Below the premise that makes sure journey of Z axis job is changeless, make transmission wedge piece angle increases 21 ° by original 18 ° 43 ′ , the radial journey when making its work by 15.
5mm increases 19mm, 3 what remain.
5 Mm is compensated by head of BE boring cutter, be about to the size of knife head radial that BE knife head compares MA is large 1.
75mm, realized MA and BE difference fast implement of housing in all cutter hub is produced (if pursue 10) . Graph 10 MA and BE are poor fast implement housing comes true in all cutter hub produces (4) system of FANUC of automation design ① : FANUC0i system uses the way that chooses machine program directly to realize different breed spare parts to control the option of the program, the means that FANUC18i system uses knob switch to choose machine program realizes different breed spare parts to control the option of the program. ② Siemens840D system: The means that Siemens840D system uses direct choice machine program respectively and the choice that realize different breed spare parts to control a process with knob switch. ③ NUM1060 system: What OP40/70 uses is the breed that informs PLC place of the choice through MA or BE pushbutton. OP80 is used when be being informed by the E parameter of exchange area NC is executing an order, undertake jumping accordingly turning. Technical innovation is in craft respect, we made two series product be on same product line above all the technology that adopt is amalgamative principle, accomplish treatment technique to agree as far as possible, put forward and came true to bore hole replace vehicle of honing, fine to replace grinding, reasonable adjusted treatment craft order. Circle of tine of watch 2 MA and the difference that BE tine encircles main technique to ask are in clamping apparatus respect, we are right original more than 10 clamping apparatus undertook redesign and be transforminged, satisfied the need of fixed position of different product part and clamp function. In cutting tool respect, the wedge orgnaization that we are redesigned and transformed spherical boring cutter to balance put oneself in another's position, cutter hub and knife head. Optimize through the experiment, chose to take the place of with boring the cutting tool of honing, efficient high accuracy that grinds with car generation. In respect of electric control system, to the cutting tool management of NUM1060 numerical control the program undertook 2 times developing, expanded sword group is mixed be opposite automatically knife and automatic compensation function. Meanwhile, we still cancelled those who need housing and tine group to distribute a car, measured a system to undertake transforming to MECALIX. Be in whole in transforming a process, the main technology that we have innovates as follows: 1.
Designed BE to differ independently fast implement housing and the technology program that BE tine encircles two kinds of spare partses, did not use abroad's mature technology. Use the principle with amalgamative craft, use the device of existing MA, transform through a series of designs that undertake to system of clamping apparatus, cutting tool and control, arrange craft reasonably, satisfied BE product requirement, came true by it is OK to can produce product of a series to be transformed only so those who carry 5 two series, variety is flexible product line. 2.
In craft respect, the aperture of honing axle shaft that changed French maturity, essence grinds the technology program of bearing external diameter, increase surplus through reasonable allocation, choose appropriate efficient cutting tool and the treatment parameter that match, came true to bore hole substitute the honing, technology that substitutes grinding with fine vehicle. 3.
Undertake 2 times developing to system of NUM1060 numerical control, expanded be opposite sword group, automatically knife and automatic compensation function. Sword set number went to 5 by 4 augment, the cutting tool that makes the machine tool implements 5 knives series is opposite life management, automatically knife and automatic compensation. 4.
Redesign the clamping apparatus of OP70 through three-dimensional imitate, undertake transforming on the foundation of German ROHM clamping apparatus, because domestic coordinate grinder cannot machine long 200mm and diameter to be more than φ ,overcame the difficult problem of the aperture of 50, came true to use a clamping apparatus spherical diameter differs inside treatment 7mm and the difference of two series with appearance very big difference fast implement housing. Epilogue plan of overall technical reformation designs this project reasonable, function is perfect, after the project is carried out, move reliable, came true flexible turn production, gained remarkable economic benefits and social benefit, its technical divisions precedes with the industry at home level. Not only such, this the automation of the clamping apparatus design of 90% , all equipment is transformed, measure machine program work out, actively transform and of equipment debugging is us finish independently independently. The example of this kind of equipment outside relying on him force to transform a country is worth to popularize. CNC Milling CNC Machining
