The alternating operation of the multiple grinding wheels 21 ensures that the grinding debris falls off during the swinging of the multilateral frame 12, thereby avoiding the heating of the grinding wheel 21 for grinding the parts. When the multiple grinding wheels 21 are used alternately, sufficient heat dissipation is performed to prevent the grinding effect of the grinding wheel 21 on the parts from being affected by long-term use, and also to prevent the grinding debris from accumulating on one grinding wheel 21 and affecting the grinding effect of the grinding wheel 21 on the parts.
[0024] refer to Figure 1 and 2 , the embodiment of driving the multilateral frame 12 to swing back and forth is described in detail:
[0025] The two sides of the polygonal frame 12 are fixedly connected with gear rings 14, and the two sides of the support frame 11 are fixedly connected with auxiliary frames 15. Each auxiliary frame 15 is rotatably connected with an upper wheel 16 that drives the gear ring 14 to rotate. Each auxiliary frame 15 is fixedly connected with a reduction motor Ⅱ17 that drives the corresponding upper wheel 16 to rotate. The two reduction motors Ⅱ17 are started, and the two reduction motors Ⅱ17 drive the two upper wheels 16 to rotate. The two upper wheels 16 rotate and engage to drive the two gear rings 14 to rotate. The two gear rings 14 rotate and drive the polygonal frame 12 to rotate. The output shafts of the two reduction motors Ⅱ17 can rotate forward and reverse, so that the polygonal frame 12 can be reciprocated by driving the two upper wheels 16 to rotate repeatedly, thereby realizing the switching of multiple grinding wheels 21, ensuring the grinding effect of the parts under long-term use of the grinding wheels 21.
[0026] refer to Figure 1 , 4 , 5, 6, 7, 8 and 9, detail embodiments of clamping parts for feeding:

The plurality of ball rods 44 are fixedly connected to the surrounding frame 43. The surrounding frame 43 is rotatably connected to two screw rods II 41. The two screw rods II 41 are respectively threadedly connected to the lateral movement frames 32. The two lateral movement frames 32 are fixedly connected to the top frames 31. The top frames 31 are rotatably connected to the screw rods III 33. The two screw rods III 33 are threadedly connected to the clamping plates 34. Thus, when the two screw rods III 33 are driven to rotate, the two clamping plates 34 are driven to slide back and forth. They are all fixedly connected with a screw sleeve III that is driven by the corresponding screw III 33. The two clamping plates 34 slide synchronously to clamp the parts. When the two screws II 41 are driven to rotate, the two screws II 41 drive the two transverse frames 32 through threads to drive the top frame 31 to slide back and forth, thereby realizing the position adjustment of the parts to be polished, and driving multiple ball rods 44 to slide on the bottom frame 53, thereby realizing the movement of the surrounding frame 43, and then realizing the arbitrary movement of the polished parts on the plane, thereby realizing the swinging of multiple grinding wheels 21 to polish any position on the parts to be polished.
[0028] refer to Figure 1 and 4 , detailed description of the embodiments of clamping parts of different sizes for grinding:
[0029] The threads of the two screw rods III 33 are rotated in opposite directions from the middle to the two sides. The two screw rods III 33 rotate to drive the two clamping plates 34 to slide synchronously in opposite directions, thereby being able to clamp and fix parts of different sizes.
[0030] refer to Figure 1 , 4 5, detailed description of the embodiment of driving the clamping plate 34 to move and the top frame 31 to slide:
[0031] The top frame 31 is fixedly connected with two reduction motors V35 for driving the corresponding screw rods III33 to rotate, and the surrounding frame 43 is fixedly connected with reduction motors IV42 for driving the corresponding screw rods II41 to rotate. The two reduction motors V35 are started, and the two reduction motors V35 drive the two screw rods III33 to rotate, thereby realizing the synchronous reverse movement of the two clamping plates 34 and fully clamping the material. The two reduction motors IV42 are started, and the two reduction motors IV42 drive the two screw rods II41 to rotate. When the two screw rods II41 rotate, the two transverse frames 32 are driven by threads to drive the top frame 31 to slide, so that the polished parts are moved in the direction of the axis of the two screw rods II41, and the parts are fully polished.

A reduction motor Ⅲ52 for driving the screw rod Ⅰ51 to rotate is fixedly connected to the bottom frame 53. When the reduction motor Ⅲ52 is started, the reduction motor Ⅲ52 drives the screw rod Ⅰ51 to rotate. When the screw rod Ⅰ51 rotates, the two transmission rods 45 are driven by threads to drive the enclosure 43 to move in a direction perpendicular to the axis of the screw rod Ⅱ41, thereby realizing the movement and adjustment of the polished parts to any position in the direction of the plane, and realizing sufficient polishing of different positions of the polished parts.

[0035] The axis of the screw rod I51 is parallel to the axis of the two screw rods III33. The axis of the screw rod I51 is perpendicular to the axis of the two screw rods II41, so that the two clamping plates 34 move in the axis direction of the two screw rods III33 to clamp the polished parts, and then the screw rod I51 drives the frame 43 to move in the axis direction of the screw rod III33 to realize the movement of the parts in the axis direction of the screw rod III33. The rotation of the two screw rods II41 drives the frame 43 to move in the direction perpendicular to the axis of the screw rod III33, so that the polished parts can be moved in any direction on the plane.
[0036] refer to Figure 1 , 2 , 3, 8 and 9, detailed description of the embodiment of the reciprocating and alternating swinging operation of multiple grinding wheels 21:

Through the alternate operation of the multiple grinding wheels 21, the multiple grinding wheels 21 are prevented from being attached with debris and overheated due to grinding, which affects the grinding effect.
