Abstract
The utility model relates to a large fine-boring hole machining fixture of a rail train traction motor base. The fixture is used for machining a workpiece and comprises an annular positioning plate, a round base and a plurality of supporting pillars used for fixedly connecting the positioning plate to the base. Through holes corresponding to threaded holes in the workpiece are formed in the positioning plate, and a protruded boss matched with the workpiece is further arranged on the positioning plate. According to the large fine-boring hole machining fixture of the rail train traction motor base, clamping connection is achieved by the utilization of the threaded holes of the workpiece, and the distribution is even, so that clamping stability is promoted. Due to the fact that the number of clamping points is large, the positioning plane of the workpiece and the positioning plane of the fixture are combined more tightly, clamping deformation does not happen easily, the number of the clamping stress points is large, stress in the machining process will be absorbed in a distributing mode, residual stress is reduced, and thus response force deformation after the machining is reduced.
Description
Technical field
The utility model relates to the large hole processing clamp of a kind of right boring, relates in particular to the large hole processing clamp of a kind of track train traction motor right boring.
Background technology
Frock, established technology equipment: the general name that refers to various tool used in the manufacture process.The quality of anchor clamps directly affects machining error, machining accuracy and machining deformation, so frock clamp will be updated in machining process, seeks better harness mode, to reduce above-mentioned error and distortion.
The track train traction motor, volume is larger, the relative wall of interstitial hole structure is thin, produce this support, operation mainly is the hole of right boring ￠ 531mm, ￠ 517.5mm and ￠ 517mm, and the diameter tolerance of hole ￠ 531mm is 0.034mm, 0.02 perpendicularity form and position tolerance take D as benchmark is arranged, the diameter of hole ￠ 517.5mm is 0.2mm, and the diameter tolerance of hole ￠ 517mm is 0.034mm, and there is take A as benchmark 0.03 squareness tolerance the bottom surface.Total run-out tolerance 0.05 take A as benchmark is arranged, also will guarantee simultaneously the perpendicularity requirement on several planes.This workpiece is processed at numerical control machining center, but suitable dress measure must be arranged.The operation of macropore as shown in Figure 1 and Figure 2 and relevant processing has specific (special) requirements to anchor clamps.The plane of orientation of workpiece and the chucking position of claw is arranged, this is easy to expect using the claw clamping work pieces, but this planar diameter reaches ￠ 650mm, and non-whole plane, the centre is the macropore of a ￠ 465mm, clamping is easy to cause the location not steady like this, also easily produces clamping deformation after the clamping, also can produce because the stress balance is too many response distortion after the processing.
The utility model content
The technical problems to be solved in the utility model is: not steady in order to solve track train traction motor clamping location, easy clamping deformation after clamping, the problem of easy stress deformation after the processing, the utility model provides the large hole processing clamp of a kind of track train traction motor right boring to solve the problems referred to above.
The technical scheme that its technical problem that solves the utility model adopts is: the large hole processing clamp of a kind of track train traction motor right boring, be used for the processing of workpiece, comprise the location-plate of annular, circular base and a plurality of pillars that are used for being fixedly connected with location-plate and base, be provided with the through hole corresponding with the screwed hole on the workpiece on the described location-plate, also be provided with the round platform of the projection that cooperates with workpiece on the described location-plate.Macropore on the workpiece is stuck on the round platform positions, after having good positioning, the screwed hole on the corresponding workpiece of the through hole on the location-plate utilizes screw to clamp in advance, and then clamping is finely tuned to lathe, finally clamps after regulating, and enters procedure.
Specifically, be provided with bolt in each pillar, described location-plate and each pillar junction are provided with counter sink, and described base and each pillar junction are provided with screw hole, and described location-plate is fixedly connected with by the bolt in the pillar with base.
Described pillar height is 80-120mm.The convenient bolt with spanner anchorage clip clamping of workpieces of pillar altitude range.
Local stiffness for fear of the large hole processing clamp of track train traction motor right boring is not enough, and described through hole and counter sink do not make progress in the same footpath of circular orientation plate.
Described pillar has 8, and corresponding counter sink and screw hole are 8, and described counter sink is distributed in each quadrant of location-plate upper surface.Be conducive to improve the stability of clamping, reduce stress, but counter sink need to be avoided the through hole setting because not making progress with the same footpath of through hole at location-plate.Counter sink circumferentially evenly arranges also in protection domain of the present utility model at the location-plate upper surface simultaneously
The beneficial effects of the utility model are, the large hole processing clamp of the utility model track train traction motor right boring utilizes the screwed hole of workpiece self to do the clamping connection, and is evenly distributed, increased the clamping stationarity, because clamping point is more, the plane of orientation of workpiece and anchor clamps is difficult for occuring clamping deformation in conjunction with tightr again, the clamping stress point is many, stress in the process can be distributed absorption, reduces stress remaining, has also just reduced the response distortion after the processing.
