When processing parts, the parts are fixed on the turntable table 102, and the swing cylinder 106 is started. The swing stud 108 is ejected, causing the swing frame 107 threadedly connected to it to rotate, and the turntable table 102 is driven to rotate through the hollow column 101, thereby adjusting the position angle of the parts. The debris generated during processing will slide along the leak-proof cover ring 104 and will not enter the base 103.

[0022] Among them, the leak-proof gasket 109 is rotatably connected to the leak-proof cover ring 104 and fixedly connected to the top of the base 103, and the rotating ring 110 is rotatably connected to the swing frame 107 and fixedly connected to the base 103.
