Description
Technical field
The present invention relates to the location technology of a kind of gear-box in process, relate in particular to localization method and the positioning clamping fixture of a kind of gear-box that in the process in the higher hole of processing concentricity requirement, uses.
Background technology
The gear-box that uses on the current track vehicle is divided into bearing-type, Non-carrying type.The Non-carrying type gear-box mainly plays a part dustproof, loading gear lubricating oil; The bearing-type gear-box in addition can also bearing load, plays supporting role.Its structure of Non-carrying type gear-box of using on the rail vehicle is split type, is divided into: upper and lower box-type; Or left and right casing formula.Its structure is substantially simple, but volume ratio is larger.Gear-box is all higher to the axiality requirement of hole and axis, but less demanding to the morpheme between axis and the axis.The perpendicularity of axis and end face requires also not high, processes relatively simple (referring to Fig. 1, Fig. 2).That uses on the current track vehicle is the Non-carrying type gear-box.
Bearing-type gear-box (referring to Fig. 3, Fig. 4) for the structure relative complex, owing to a diameter is arranged all less than the necking down 04 in hole 02, hole 03 on cylindrical 01 and hole 02, hole 03 center line, boring cutter can't pass through, can only manually fill cutter, the concentricity in cylindrical 01 and hole 02, hole 03 on the very difficult assurance one side center line, and hole 02 is not more than 0.02mm with hole 03, hole 05 with the depth of parallelism requirement of the 06 liang of center line in hole.Be difficult to the precision that assurance is processed with present process technology, labour intensity, cost and operating efficiency are extremely low in addition.
A kind of method of prior art is at twice clamping of fine finishining.At first, fine finishining one side opening end face carries out semifinishing to this side opening.Secondly, secondary clamping is changed the end face fine finishining that mold is finished opposite side, processes zero point for the axiality hole that the centering clamped one time processes behind secondary clamping that guarantees two holes on the axis is decided to be, and finishes the processing in two holes in a side.Referring to Fig. 5, Fig. 6, Fig. 7.
The shortcoming of this method is that the secondary clamping position error increases; Centering and clamping time increase; Labour intensity is strengthened; Because need secondary clamping, need design two cover molds finish respectively processing, cost increases, and changing simultaneously the mold centering time also increases.
The another kind of method of prior art also is that clamping is finished fine finishining at twice, difference is for the complicated a little gear-box of structure, and cutter can't carry out respectively accurately machined gear-box from a side to be taked at first to finish a hole assurance axiality on the axis in a side; The hole of secondly finishing another axis behind the secondary clamping centering guarantees the axiality in hole on the axis.
Such processing method shortcoming is identical with the shortcoming of above-mentioned prior art, only in use and the undemanding situation of two axial lines form and position tolerance.
Summary of the invention

Utilize the rotating high accuracy of machining center platform to allow the center line of gear-box width drop on the centre of gyration, guarantee the cylindrical 01 of gear-box and the concentricity (as shown in Figure 4) in hole 02, hole 03.So namely can overcome because the shortcoming that the cutter that necking down 04 causes can't pass through, can avoid again can realizing that in addition clamped one time finishes all finishing step contents because rotation causes main shaft to stretch out the error that causes different in size (it is poorer that main shaft stretches out longer rigidity).
For overlapping with the mold centre of gyration, the center line of guaranteeing the gear-box width must guarantee that the mold bottom sides guarantees in X1 ± 0.02mm scope to the distance of centre bore; The axis that the axle suspension bearing box direction is installed will be in Y1 ± 0.02mm scope to side end face, bottom distance.Also will be as benchmark when semifinishing, unifying datum guarantees the even of allowance.
The end face of mold the first positioning baffle is vertical with the plane, end face place of the second positioning baffle, guarantees that the end face of two the second positioning baffles is at same plane.
Overlap with platform (workbench) centre of gyration of machining center by bottom center hole, utilize the concentricity of the two side holes after the high characteristics of machining center or lathe self rotating accuracy are guaranteed to process.Utilize the first positioning baffle, the second positioning baffle and spacer pad to guarantee that gear-box side and end face are vertical with mold base plate upper surface and lower surface.Between the locating surface (bottom surface, side and end face) of actual clamping middle gear case and mold locating surface (lateral fiducial face, vertically datum level and vertical to datum level), be bound to exist gap delta, require gap delta≤0.03mm.With axle the mold centre bore is linked to each other with the workbench center when mold uses, guarantee centre bore and the work table rotation center superposition fit clearance δ 1≤0.02mm of mold base plate.The end face that guarantees the second positioning baffle is vertical with main shaft, and perpendicularity must not surpass 0.02mm.Clamp with pressing plate at last.
When designing mold, require the median plane of gear-box width on the centre of gyration for the ease of processing; Look for the rotating accuracy of table check lathe after the centre of gyration will overlap with the centerline hole line of gear-box one side and be convenient to turn round in addition, the suitable lathe of making compensates.
Use and to use according to designing requirement in order to ensure bearing-type gear-box fine finishining mold, must before mold and table latch, guarantee centre bore and the work table rotation center superposition fit clearance δ 1≤0.02mm of mold base plate.The end face that guarantees the second positioning baffle is vertical with main shaft, and perpendicularity must not surpass 0.02mm.
Adopt the present invention program, when fine finishining, guaranteed the endoporus of gear-box processing and the concentricity of cylindrical, and the depth of parallelism of cylindrical 01, hole 02, hole 03, hole 04 and hole 05, hole 06 (as shown in Figure 4) two axial lines, guaranteed the perpendicularity of end face and axis.Saved cost savings the time, reduced labour intensity, improved the qualification rate of product, efficient increases greatly.
Utilize the gear-box fine finishining revolution mold of the high characteristics design of work table rotation precision, the realization clamped one time is finished fine finishining.The error that clamped one time has avoided resetting to cause descends percent defective greatly, and percent defective reaches 5% during trial-production, drops to now 0.15%; The centering time shortens greatly, and originally fine finishining needs twice about 30 minutes of clamping time spent, only needs 10 minutes now; Clamped one time labour intensity reduces greatly; Be willing to have the cost of two width of cloth molds about 80,000, only need now about 3.5 ten thousand just can solve and saved greatly cost; But two classes of processed finished products were about 3 in one day originally, but processed finished products 6-7 now, production efficiency significantly improves.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
