[0043] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0044] The working principle of the present invention is as follows: the mechanical parts are placed behind the two clamping plates 55, and then the screws 54 on the two clamping plates 55 are rotated respectively, so as to drive the two clamping plates 55 to approach each other, and then the mechanical parts are clamped by the two clamping plates 55, so as to fix the mechanical parts, and the rubber pads 56 can be used to protect the mechanical parts, and then the adjustment plate 3 is pressed downward to determine the position of the grinding disc 733 and the mechanical parts, and then the adjustment plate 3 is released to restore it to its original state, and the pull rod 762 is pulled upward by the connecting block 764, thereby driving the lower pressing plate 7 7 moves upward, during which spring 763 is in a compressed state, and the first plug plate 783 is pulled out from the teeth of the first ratchet 781, and the second plug plate 784 is pulled out from the teeth of the second ratchet 782. At this time, the rotating wheel 75 is rotated to drive the adjustment seat 71 to rotate through the support rod 74, and the adjusting seat 71 is rotated by rotating the rotating wheel 75 to adjust the position of the adjustment seat 71, thereby adjusting the position of the grinding disc 733 to reduce the inclination of the adjustment seat 71. After that, the connecting block 764 is released, and the lower pressure plate 77 is reset under the elastic force of the spring 763. Therefore, the first plug plate 783 is inserted into the teeth gap of the first ratchet 781, and the second plug plate 784 is inserted into the teeth gap of the second ratchet 782. Therefore, the adjustment assembly 78 is locked to the adjustment seat 71, so that when grinding, the grinding disc 733 fits better with the mechanical parts and components, improving the grinding effect of the parts and components. Then, the grinding motor 732 is turned on, so that the grinding motor 732 drives the grinding disc 733 to rotate, and then the adjustment plate 3 is pressed downward, so that the grinding disc 733 can fit on the mechanical parts and components, so that the mechanical parts and components can be polished with a good grinding effect. At the same time, by rotating the turntable 526 , so that the turntable 526 drives the screw rod 525 to rotate, the first connecting groove 41 is used to limit the first clamping plate 521, and the second connecting groove 42 is used to limit the second clamping plate 522, so that the positioning plate 51 can move in the second connecting groove 42, and the movement of the second connecting groove 42 can be used to fine-tune the mechanical parts in the horizontal direction. When grinding, it is necessary to press down the adjustment plate 3. Under the influence of the adjustment plate 3, the grinding disc 733 moves in the horizontal direction. Therefore, by moving the positioning mechanism 5 to adjust the position of the mechanical parts, it is beneficial to improve the grinding effect of the parts.
