Abstract

The invention provides a clamp for a motor end cover. The technical problems that a traditional tool is tedious in operation, unstable in quality and low in clamping efficiency can be solved. The clamp comprises a bottom plate and is characterized by further comprising a rotary table, a workpiece positioning mechanism, a workpiece pressing mechanism, a bottom plate positioning mechanism and a positioning column fixing mechanism, wherein a rotating shaft is fixed to the rotary table, the bottom plate is in a circular shape and rotationally supported on the rotating shaft, the workpiece positioning mechanism comprises positioning columns and positioning pins, the bottom plate is provided with a plurality of bottom plate through holes which are distributed around the rotating shaft in the circumferential direction, the positioning columns are inserted in the bottom plate through holes correspondingly, the positioning columns are in a step shape and each comprise an upper positioning portion and a lower supporting portion, each lower supporting portion is provided with a reference plane in fit with the lower end face of the motor end cover, a blanking hole matched with a threaded hole and a polished hole in the motor end cover, a workpiece positioning hole and a shoulder portion protruded outwards, the positioning pins are inserted into the workpiece positioning holes, and the workpiece pressing mechanism comprises pressing bolts and pressing plates.

Description

technical field [0001] The invention relates to the technical field of processing of motor parts; in particular, it relates to a clamp for a motor end cover. Background technique [0002] A kind of motor end cover 10, its structure is as figure 1 , figure 2 As shown, it includes a cover body 11 and an annular flange 12 arranged on the cover body 111. The edge of the cover body 11 is provided with a light hole 111 and a shaft hole 113 sequentially communicated with the groove 122 surrounded by the annular flange. And the bearing groove 112; the annular flange 12 is provided with a threaded hole 121 passing through the cover body 111 . Before machining the threaded holes, the motor end cover needs to be clamped on the tooling. The reliability and efficiency of the clamping directly affect the product quality and output. At present, the traditional tooling used is cumbersome to operate, unstable in quality, and low in clamping efficiency. Contents of the invention [000...
