Description

Technical Field

[0001] The utility model relates to the technical field of motor shell processing, in particular to a motor shell processing tool. Background Art

[0002] like Figure 1 The motor casing shown is prone to deformation during processing when using a traditional vise fixing method due to its thin wall. For example, a fixing tool for motor casing processing, with publication number CN211916158U, discloses a base, a first clamp, a second clamp and a mounting seat, wherein the bottom of the base is fixed with a mounting seat by bolts; a fixing plate is welded to the upper part of the base, and two threaded rotating rods are fitted and installed on the fixing plate, one end of the threaded rotating rods are fitted and installed in the bearing, the bearing is fixedly glued in the fixing block, and the fixing block is welded to the first clamp; a second clamp is provided at the opposite end of the first clamp; a connecting plate is welded to the side wall of one end of the second clamp, and a threaded cross bar is inserted and provided on the connecting plate, and a fastening block is provided on the outer spiral of the threaded cross bar. By setting the first clamping plate and the second clamping plate with adjustable positions, the two are coordinated with each other to conveniently achieve the purpose of fixing the motor housing. Although the purpose of fixing can be achieved, due to the thin wall of the motor housing, deformation will occur during the processing, resulting in the shape and position tolerances failing to meet the technical requirements, causing abnormal noise in the motor test after assembly. In order to prevent processing deformation, a motor housing processing tool is urgently needed to solve the above technical problems. Utility Model Content

[0003] In order to solve the above-mentioned technical problem or one of the technical problems existing in the prior art, the utility model discloses a motor casing processing tool, including a mounting table, a fixing table, a through hole and a connecting bolt are provided above the mounting table, and support legs are provided at the four corners of the bottom of the mounting table. The fixing table is screwed to the center of the top surface of the mounting table, the through hole is opened on both sides of the fixing table, the connecting bolt is arranged in the through hole, and the fixing table is a convex column shape.

[0004] Furthermore, the mounting platform is rectangular.

[0005] Furthermore, the supporting leg is L-shaped.

[0006] Furthermore, countersunk screw holes are provided at the four corners of the mounting platform and the bottom of the supporting leg. The mounting platform is screwed to the top of the supporting leg through the countersunk screw holes and bolts, and the bottom of the supporting leg is screwed to the bottom workbench through the countersunk screw holes and bolts.

[0007] Furthermore, there are six through holes and six connecting bolts.

[0008] Furthermore, the size of the fixing platform is the same as the size of the groove at the bottom of the motor housing.

[0009] Compared with the prior art, the utility model eliminates the previous vise clamping method, is more convenient to install, can effectively prevent the deformation problem of workpiece during processing, improves the motor test pass rate, reduces parts rework, and saves time for manual single-piece processing.
