[0020] The X-axis sliding assembly 100 and the Z-axis sliding assembly 200 have the same structure. Both the X-axis sliding assembly 100 and the Z-axis sliding assembly 200 include a slide 2, two linear guides 3, a slide plate 4, a servo motor 5, a screw 6 and a fixed seat 7. The two linear guides 3 are horizontally fixed on the slide 2. The screw 6 and the fixed seat 7 are placed between the two linear guides 3. A first threaded hole is provided on the fixed seat 7. The screw 6 extends into the first threaded hole and is threadedly connected to the first threaded hole. The servo motor 5 is fixed to one side of the fixed seat 7, and the output end of the servo motor 5 is fixedly connected to one end of the screw 6. The slide plate 4 is fixed to the fixing seat 7 by screws, and the slide plate 4 is slidably connected to the two linear guide rails 3. The output end of the servo motor 5 rotates to drive the lead screw 6 to rotate. Since the lead screw 6 is threadedly connected to the first threaded hole of the fixing seat 7, the fixing seat 7 can be driven to slide along the length direction of the linear guide rail 3, so that the slide plate 4 fixed on the fixing seat 7 slides accordingly. The X-axis sliding assembly 100 and the Z-axis sliding assembly 200 are respectively arranged in the X-axis and Y-axis directions, thereby making the slide plates 4 in the X-axis sliding assembly 100 and the Z-axis sliding assembly 200 slide in the X-axis and Z-axis directions respectively.

[0021] The Y-axis sliding assembly 300 is placed on the slide 4 of the Z-axis sliding assembly 200. The Y-axis sliding assembly 300 includes a support seat 20, a support seat slide 21, a grinding spindle seat 22, a feed moving screw 23, a dial handwheel 24, a grinding spindle 25 and a grinding wheel head 26. The support seat 20 is fixed on the slide 4 of the Z-axis sliding assembly. The support seat 20 is triangular in shape. The support seat 20 is provided with a receiving groove 201 for accommodating the feed moving screw 23. The support seat slide 21 is provided with a second vertically arranged threaded hole. The feed moving screw 23 is placed in the receiving groove 201. The feed moving screw 23 extends into the second threaded hole and is threadedly connected to the second threaded hole. The dial handwheel 24 is fixed to the top of the support seat 20, and the top of the feed moving screw 23 passes through the second threaded hole and is fixedly connected to the bottom of the dial handwheel 24. Turning the dial handwheel 24 can rotate the feed moving screw 23 and make the support seat slide 21 slide up and down. The grinding spindle seat 22 is fixed to the support seat slide 21, and the grinding spindle 25 is fixed to the grinding spindle seat 22. The grinding wheel head 26 is fixed to the output end at the bottom of the grinding spindle 25. The grinding wheel head 26 can approach or move away from the workpiece 27 as the support seat slide 21 moves up and down. The grinding spindle 25 drives the grinding wheel head 26 to rotate at high speed to grind the workpiece 27.

[0022] A clamping mechanism is provided on the slide plate 4 of the X-axis sliding assembly 100, and the clamping mechanism includes a workpiece spindle seat 8, a workpiece spindle 9, a mounting seat 10, a fixture 11, a rotating motor 12, a motor pulley 13, a synchronous belt 14, a rotary encoder 15, a spindle pulley 16, a clamping air circuit 17, an angle plate 18 and an angle base plate 19. The angle base plate 19 is fixed on the slide plate 4 of the X-axis sliding assembly, and the angle plate 18 is placed on the angle base plate 19. An arc groove 181 is provided on the angle plate 18, and a sliding end 191 is provided on the angle base plate 19. The sliding end 191 extends into the arc groove 181 and is slidably connected with the arc groove 81, so that the angle between the angle plate 18 and the angle base plate 19 can be adjusted.

[0023] The cross section of the mounting seat 10 is L-shaped. The mounting seat 10 is fixed on the angle plate 18. The workpiece spindle seat 8 is fixed on the mounting seat 10. The workpiece spindle 9 is rotatably connected to the workpiece spindle seat 8. The fixture 11 is installed and connected to the workpiece spindle 9. One end of the workpiece spindle 9 passes through the mounting seat 10. The spindle pulley 16 is sleeved on the end of the workpiece spindle 9.

The spindle pulley 16 and the motor pulley The wheel 13 is connected for rotation via a synchronous belt 14, and the clamping air circuit 17 is fixed on the workpiece spindle seat 8 and connected to the workpiece spindle 9. The clamping air circuit 17 can change the air pressure, and the air pressure drives the clamp 11 to move and clamp the workpiece 27. The rotating motor 12 drives the motor pulley 13 to rotate. Since the synchronous belt 14 is connected to the motor pulley 13 and the spindle pulley 16, the spindle pulley 16 and the workpiece spindle 9 are driven to rotate, so that the clamped workpiece 27 can rotate to facilitate the adjustment of the processing surface. The rotary encoder 15 can feedback the rotation angle to the rotating motor 12 to ensure the accuracy of the rotation angle of the workpiece spindle 9.

[0024] The working principle of the embodiment of the utility model is: the workpiece 27 is clamped into the fixture, and the clamping air circuit 17 is started so that the air pressure pushes the fixture 11 to clamp the workpiece 27, and various polygonal workpieces 27 can be processed; by starting the servo motor 5 in the X-axis sliding assembly 100 and the Z-axis sliding assembly 200, the slide plate 4 in the X-axis sliding assembly and the Z-axis sliding assembly can be adjusted to a suitable position, and the support seat slide plate 21 in the Y-axis sliding assembly 300 can be controlled by manually rotating the dial hand wheel 24, so as to drive the grinding wheel head 26 to move up and down, and the grinding spindle 25 drives the grinding wheel head 26 to rotate at high speed to grind the processing surface of the workpiece 27 to be processed; when a processing surface of the workpiece 27 is ground, the rotating motor 12 drives the motor pulley 13 to rotate, and the synchronous belt 14 drives the spindle pulley 16 and the workpiece spindle 9 to rotate, so that the clamped workpiece 27 rotates accordingly, and the remaining processing surfaces can continue to be processed. In addition, the angle plate 18 can be pushed to move on the angle bottom plate 19 along the arc groove 181, and the angle of the workpiece 27 can also be adjusted to adapt to grinding.
