[0002] A motor refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. A motor is generally composed of a stator, a rotor, bearings, end covers, and a motor casing. When processing the motor casing, it is necessary to drill holes on the motor casing to facilitate the installation of the motor on the motor casing. Generally, in order to facilitate drilling holes on the outer wall of the motor casing, the motor casing needs to be pressed and fixed.

[0003] A clamping device for motor processing is proposed in the Chinese utility model patent with application number 201921500473.2, including a base, a fixed plate fixedly connected to the top of one side of the base, and a top plate connected to the top of the fixed plate by bolts, a bracket fixedly connected to one side of the top of the top plate, and a threaded barrel is provided in the middle position of the top of the bracket, the internal thread of the threaded barrel is connected to a screw, and the tops of both sides of the screw are welded with a handle, a slide rail is welded to the top of one side of the fixed plate, and a slider is slidably connected to the inside of the slide rail, a lifting plate is welded to the middle of one side of the slider, and the bottom of the screw is rotatably connected to the top of one side of the lifting plate through a bearing. When the utility model is used, the rear cover end of the motor is placed inside the pressing cover, and it is fixed by adsorption by a permanent magnet. By rotating the pressing cover by the handle, the orientation of the rear cover end of the motor can be adjusted to make it compatible with the front cover end of the motor.

[0004] After the improvement, the above device is placed inside the pressing cover with the rear cover end of the motor, and fixed by adsorption by permanent magnets. By turning the pressing cover with a handle, the position of the rear cover end of the motor can be adjusted to match the front cover end of the motor. However, during use, its clamping mechanism will clamp the objects to be clamped from both ends, which may easily cause the clamped objects to be moved when being pressed during use, resulting in inconvenience in use. For this reason, we propose a clamping device for machining. Utility Model Content
