[0024] In the embodiment of the present invention, the L-shaped positioning seat 113 can be used to contact the regular hexagonal seat 211 to ensure that the regular hexagonal tube 21 can be rotated to a suitable angle after the rotation adjustment of the rotation adjustment grinding and polishing mechanism 2 is completed, so that the metal parts can be ground and polished. Compared with other fixed-angle rotation mechanisms, the rotation accuracy of this method does not need to be too high.

[0027] In the embodiment of the present invention, the hexagonal seat 211 is provided to conveniently fix the hexagonal tube 21 and ensure the accuracy of its rotation angle, so that the grinding sandpaper 256 or the polishing disc 255 can fully contact the metal part.

[0030] In the embodiment of the present invention, the regular hexagonal cylinder 21 and the driven sleeve shaft 22 are connected by a fixed bearing 112, which can ensure the smooth rotation of the other end of the regular hexagonal cylinder 21. At the same time, the connection between the driven sleeve shaft 22 and the hydraulic cylinder 111 can facilitate the lifting and lowering control of the regular hexagonal cylinder 21.

[0031] In the embodiment of the present invention, the drive shaft 2241 and the small pulley 2242 are arranged, and the large pulley 2253 is driven to rotate by the drive belt 2254, so that the grinding motor 224 can drive the positioning shaft 2252 to rotate, and then utilize the magnetic coupling method to make the strong magnetic coupling main rotor 226 drive the strong magnetic coupling sub-rotor 242 to rotate, so that the transmission shaft 24 can rotate, thereby facilitating the transmission of power and simplifying its structure.

[0032] In the embodiment of the present invention, by utilizing the setting of the strong magnetic coupling main rotor 226, the grinding motor 224 can only drive the grinding disc 254 or polishing disc 255 at the corresponding position to rotate, thereby preventing other grinding discs 254 or polishing discs 255 exposed to the outside from rotating, so as to ensure the safety of the device. At the same time, after the regular hexagonal tube 21 is rotated to a suitable angle, it can drive the corresponding grinding disc 254 or polishing disc 255, thereby making its operation easier and more convenient, while simplifying its structure and reducing its structural complexity.

[0033] The transmission shaft 24 is horizontally arranged above the center of each side surface of the regular hexagonal tube 21 and is connected through a bearing seat and a bearing. A plurality of bevel gears 241 are installed on it. The bevel gears 241 mesh with the bevel gears 1 232, and a strong magnetic coupling auxiliary rotor 242 is installed at one end.

[0034] In the embodiment of the present invention, the transmission shaft 24 is arranged above the center of each side surface of the regular hexagonal cylinder 21, so that it can be easily positioned so that all the transmission shafts 24 inside the regular hexagonal cylinder 21 can be on the same circle, and through the arrangement of the strong magnetic coupling sub-rotor 242, when it rotates to the bottom, it can be rotated by magnetic coupling, thereby ensuring efficient grinding of the device, reducing power waste, and not causing adverse effects on the rotation of the regular hexagonal cylinder 21.

The grinding sleeve shaft 253 is slidably mounted on the corresponding grinding main shaft 23 and the grinding secondary shaft 233. A grinding disc 254 is installed at the lower end of the grinding sleeve shaft 253.

[0036] In the embodiment of the present invention, the same-position baffle 25 is used to drive the grinding sleeve shaft 253 to rise and fall synchronously, and the grinding force is controlled by the elasticity of the compression spring 252. On the one hand, the efficiency of the metal part grinding can be ensured, and on the other hand, the grinding disk 254 can be placed in the same horizontal plane so that it can rise and fall synchronously, thereby avoiding the problem of the metal part colliding with the grinding disk 254 during reciprocating rotation, causing damage to the grinding disk.
