The intermediate sleeve 1331 is rotatably connected with the pin shaft 1333, and the intermediate sleeve 1331 is fixedly connected with the first support frame 131. The end sleeves 1332 are in interference fit with the pin shaft 1333, and the pin shaft 1333 is fixedly connected with the second support frame 132.

[0060] Specifically, the intermediate sleeve 1331 is fixedly connected with the fixed rod 1313 of the first support frame 131.

[0061] Through the fixed connection of the pin shaft 1333 and the second support frame 132, the interference fit between the pin shaft 1333 and the end sleeve 1332 fixes the pin shaft 1333 relative to the second support frame 132. Through the rotatable connection between the pin shaft 1333 and the intermediate sleeve 1331, and the fixed connection between the intermediate sleeve 1331 and the fixed rod 1313 of the first support frame 131, the rotatable connection between the pin shaft 1333 and the first support frame 131 is realized, and the rotatable connection between the first support frame 131 and the second support frame 132 is realized.

[0062] Further, a plurality of positioning holes are formed on the pin shaft 1333, and the plurality of positioning holes are arranged at intervals along the outer periphery of the pin shaft 1333. A limiting hole is formed on the sleeve. The limiting hole is formed on the intermediate sleeve 1331.

[0063] That is, by selectively making a certain positioning hole correspond to the limiting hole and inserting the locking rod 1334, the position of the pin shaft 1333 relative to the intermediate sleeve 1331 is adjusted, so as to adjust the angle of the second support frame 132 relative to the first support frame 131, and further adjust the angle of the grinding machine 12 mounted on the second support frame 132 relative to the workpiece 2, so that the angle of the grinding wheel 122 meets the angle requirement of the bevel processing.

[0064] In combination with Figures 13-16The second support frame 132 is connected with the polishing machine 12. The second support frame 132 is provided with a second mounting member for connecting and fixing the polishing machine 12. The second support frame 132 comprises two ear plates 1321 arranged in parallel and spaced apart. The two ends of each ear plate 1321 are respectively provided with a connecting hole and a mounting hole. The connecting hole is used for the pin shaft 1333 to pass through. The mounting hole is used for the mounting shaft of the polishing machine 12 to pass through. The two ear plates 1321 are used for clamping the lower part of the polishing machine 12.

[0065] Specifically, the ear plate 1321 is arranged in one-to-one correspondence with the two end portion sleeves 1332. Each ear plate 1321 is fixed to the outer side of the corresponding end portion sleeve 1332.

The two clamping rings 1322 can enclose a receiving cavity for accommodating the upper part of the polishing machine 12. The two clamping rings 1322 are connected with the connecting member 133 through the ear plate 1321. The two clamping rings 1322 and the ear plate 1321 jointly constitute the second mounting member.

[0067] Each clamping ring 1322 comprises a ring structure and a connecting structure arranged at both ends of the ring structure. The connecting structure is in the form of a flat plate. Each connecting structure is provided with a bolt hole. The two ends of each clamping ring 1322 are provided with a bolt. The connection between the two clamping rings 1322 is realized through the screw connection between the bolt and the bolt hole. Moreover, the spacing between the two clamping rings 1322 can be adjusted by adjusting the tightness of the bolt to adapt to polishing machines 12 of different sizes.

[0068] Specifically, the two ear plates 1321 are connected through a transition plate 1323. The transition plate 1323 is perpendicular to the two ear plates 1321.
