[0028] A sliding rod 12 is slidably connected inside the fixed tube 11, rotating balls 13 are rotatably connected inside both the sliding rod 12 and the connecting seat 10, and a base 14 is rotatably connected to the outside of the rotating balls 13.
[0029] A clamping plate 15 is fixedly connected to the bottom of the base 14, and a sliding strip 16 is slidably connected inside the clamping plate 15.
[0030] It should be noted that when the staff needs to adjust the position of the angle grinder body 65, first make the first cylinder 3 start to work. When the first cylinder 3 works, it can drive the top plate 5 to slide inside the fixed plate 2, and then the height of the angle grinder body 65 can be adjusted. At the same time, make the first lead screw mechanism 61 start to operate. Under the action of the first lead screw mechanism 61, the horizontal position of the angle grinder body 65 can be adjusted. When the second lead screw mechanism 63 operates, the longitudinal position of the angle grinder body 65 can be adjusted. Thus, the angle grinder body 65 can perform grinding operations on the workpiece at the top of the placement plate 4 at various positions. When the grinding angle of the angle grinder body 65 needs to be adjusted, first the staff starts the second cylinder 9. Under the action of the second cylinder 9, the connecting seat 10 can move. When the connecting seat 10 moves, it drives one end of the angle grinder body 65 through the rotating ball 13 and the base 14, and then drives one end of the angle grinder body 65 to move, so that the angle grinder body 65 is at a certain angle, and thus the grinding angle of the angle grinder body 65 can be adjusted.

[0035] It should be noted that when the staff performs grinding operations on the workpiece, they first need to position the workpiece. Place the workpiece on the top of the placement plate 4. Under the action of the first spring 19, it can drive the movement of the moving block 20, and then make the soft plate at one end of the screw rod 26 contact the outer side of the workpiece. Rotate the rotating tube 21. Under the action of the rotating tube 21, drive the movement of the screw rod 26, so that the soft block at one end of the screw rod 26 can be closely attached to the outer side of the workpiece, and then the workpiece can be initially fixed. After positioning, make the fourth lead screw mechanism 22 start to operate. The fourth lead screw in the fourth lead screw mechanism 22 is provided with equally spaced external threads with opposite thread directions on its outer side, so that the pressure plate 25 can move to the specified position, thereby positioning the workpiece placed on the top of the placement plate 4 and preventing it from sliding during the grinding operation.
[0036] The working principle of a grinding angle adjustment structure provided by the present utility model is as follows:
[0037] When the staff needs to perform grinding operations on the workpiece, first place the workpiece on the top of the placement plate 4, and then adjust the positions of the moving block 20 and the pressure plate 25, so that the soft block at one end of the screw rod 26 and the pressure plate 25 can position the workpiece. After positioning, adjust the position of the angle grinder body 65, make the first cylinder 3 start to operate. Under the action of the first cylinder 3, the height of the angle grinder body 65 can be adjusted. Then make the first lead screw mechanism 61 start to operate, so that the horizontal position of the angle grinder body 65 can be adjusted. Make the second lead screw mechanism 63 start to operate, and then the longitudinal position of the angle grinder body 65 can be adjusted. When the staff needs to adjust the grinding angle of the angle grinder body 65, first start the second cylinder 9. Under the action of the second cylinder 9, it can drive the movement of the connecting seat 10, and then the connecting seat 10 can drive the angle grinder body 65 to move through the rotating ball 13 and the base 14, so that the angle grinder body 65 can be at a certain angle, thereby adjusting the grinding angle of the angle grinder body 65, and facilitating the staff to perform grinding operations on the workpiece through the angle grinder body 65.
