A first bevel gear is installed on the rotating shaft at the end of the rotary joint, and a stepper motor is installed on the right support seat. A second bevel gear is installed on the output shaft of the stepper motor. The second bevel gear meshes with the first bevel gear on the rotary joint. The positioning mounting plate is provided with a plurality of parallel and spaced mounting positioning hole groups, and each mounting positioning hole group is correspondingly provided with a positioning pin.

Then, the machining device is fixed on the worktable of the vertical CNC machine, and dial indicator calibration is performed; the required tools are programmed and installed. Next, a stepper motor drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate the rotary joint, rotating the cylinder seat mounted on the positioning mounting plate to the surface to be machined. The vertical CNC machine then machines this surface. After machining, the stepper motor again drives the cylinder seat mounted on the positioning mounting plate to rotate to the next surface to be machined, and the vertical CNC machine processes the next surface until all surfaces are machined.

[0006] Preferably, the base plate is provided with four square mounting holes to facilitate the overall installation of the processing device.
