Then, the protective cover 6 can be removed by pulling it upward.

[0031] In the present invention, the working principle of the device is as follows:

[0032] When in use, the workpiece is placed on the electromagnetic suction cup 4, and the electromagnetic suction cup 4 firmly adsorbs and fixes the workpiece. When the angle of the workpiece needs to be adjusted, the first motor 301 is started to drive the worm 302 to rotate, and at the same time drives the gear 306 and the fixing rod 307 to rotate, and finally drives the electromagnetic suction cup 4 to rotate, so as to adjust the angle between the electromagnetic suction cup 4 and the workpiece.

The first motor 301 and the second motor 303 cooperate with each other to realize multi-angle adjustment of the workpiece, increase flexibility, and meet the needs of oblique grinding of the workpiece.

[0033] After the workpiece is adjusted, the protective cover 6 is inserted into the interior of the workbench 2 so that the bottom of the protective cover 6 squeezes the clamping block 503. Since one side of the clamping block 503 is arc-shaped, it is squeezed and retracted into the groove 501, and the spring 502 is compressed. Then the protective cover 6 completely enters the interior of the workbench 2. At this time, the clamping block 503 and the clamping groove 8 are on the same horizontal line. Then the spring 502 is reset due to the action of the force, driving the clamping block 503 to enter the clamping groove 8 to complete the clamping, and fix the protective cover 6. Then the workpiece is ground by the grinding wheel 10. During the processing, the protective cover 6 is used to prevent debris and cutting fluid from splashing. When the protective cover 6 needs to be removed, just pull the two handles 505 outward to drive the clamping block 503 to retract into the interior of the groove 501 and disengage from the clamping groove 8. Then pull the protective cover 6 upward to remove it.
