[0044] Specifically, the guide screw 403 passes through the interior of the guide groove 405, and the locking nut 404 is threaded onto the surface of the guide screw 403.

[0045] Furthermore, the pressure plate body 402 can slide along the axis of the guide screw 403 via the guide groove 405 to guide the pressure plate body 402. After the pressure plate body 402 presses the workpiece 5 of the air inlet cylinder, the locking nut 404 can be rotated and moved downward along the axis of the guide screw 403 to lock the pressure plate body 402.

[0053] In summary, the pressure plate assembly 4, in cooperation with the pressure plate body 402 and the lower pressure column 406, stably clamps the outer edge of the intake cylinder workpiece 5. Under the action of the first positioning assembly 6 and the second positioning assembly 7, the intake cylinder workpiece 5 is firmly held in place by multiple second moving steel ball positioning screws 603 from the inside and outside, preventing the intake cylinder workpiece 5 from deviating and the vibration generated during processing.
