The device comprises a housing with an opening at the top, a support plate that slides up and down is fixed inside the housing, and a motor end cover is placed on the support plate. The support plate is provided with a symmetrical and penetrating slide groove along the diameter direction, and a clamping block that slides laterally is fixed inside the slide groove. A slider is provided below the clamping block, and an elliptical cam is provided between the sliders. The cam is connected to a driving device that drives the cam to rotate, and a first rebound spring is provided on the side of the slider away from the cam. The utility model realizes horizontal clamping of the motor end cover by rotating the cam and cooperating with the first rebound spring to separate or close the two clamping blocks; by rotating the support rod through the threaded connection between the support plate and the rotating rod, the support rod is rotated to move the support plate up and down, and the clamping plate is used to realize vertical clamping of the motor end cover, thereby achieving double clamping.

A clamping structure 4 is fixedly installed on the top of each movable block 3. The clamping structure 4 includes a support shell 5, a plurality of telescopic rods 6, a plurality of telescopic springs 7 and a plurality of retaining blocks 8. The support shell 5 is fixedly installed on the top of the movable block 3.

Each telescopic spring 7 is sleeved on the outside of the corresponding telescopic rod 6, and each telescopic spring 7 is located between the corresponding inner wall of the support shell 5 and the retaining block 8. The retaining block 8 is affected by the telescopic rod 6 and can be extended and retracted to different degrees according to the edge shape of the motor end cover. At the same time, after compression, the telescopic spring 7 also causes the retaining block 8 to produce a tightening force on the motor end cover, thereby fully clamping and limiting the motor end cover.

[0024] A support plate 9 is fixedly installed in the inner cavity of the processing table 1, and a telescopic cylinder 10 is fixedly installed at the bottom of the inner cavity of the processing table 1. The top output end of the telescopic cylinder 10 is fixedly connected to a driving rod 11. The driving rod 11 passes through the surface of the support plate 9, and the driving rod 11 is slidably set on the surface of the support plate 9. When the telescopic cylinder 10 is started, the driving rod 11 is driven to move upward, and the driving rod 11 can move up and down on the support plate 9.

[0025] A plurality of slide grooves 12 are provided on the surface of the support plate 9 at equal angles. Each slide groove 12 is located directly below the corresponding movable groove 2 . The slide groove 12 is used to limit the movement of the slider 13 .
