In particular, for the workpiece 12 with different diameter shaft structure, process holes or holes are arranged on the upper and lower end surfaces to facilitate the insertion of the center pin 7 and the passage of airflow, while ensuring the accuracy of positioning.

[0055] The wind knife fixing plate 6 is a key component connecting the wind knife and the driving mechanism.

[0058] In the specific working process, first, the workpiece 12 to be cleaned is placed on the bottom center 8, and the plunger 7 is inserted into the process hole at the upper end of the workpiece through the driving of the plunger cylinder 5, so as to firmly hold the workpiece. Then, the servo motor 1 is started, and the wind knife fixing plate 6 and the axial wind knife 10 and the radial wind knife 11 thereon are moved to the preset position through the lead screw module 2. Then, the axial wind knife and the radial wind knife are started simultaneously to generate high-speed and high-pressure air flow for omnidirectional cleaning of the surface of the workpiece. At the same time, the air channel in the plunger 7 also introduces air flow to clean the axial hole in the inside of the workpiece. With the driving of the servo motor, the wind knife fixing plate drives the wind knife to move up and down along the surface of the workpiece, so as to repeatedly clean each part of the workpiece and ensure that there is no omission. Finally, when the entire surface of the workpiece is thoroughly cleaned, the plunger cylinder is released, the plunger is withdrawn to the original position, and the workpiece can be taken off from the bottom center to complete the entire cleaning process.
