[0014] The present invention provides an automated milling processing device for manufacturing a motor shaft. It has the following beneficial effects:

[0015] (1) The motor shaft manufacturing automated milling processing equipment limits the cylindrical workpiece by means of a V-shaped plate. The cylindrical workpiece cannot rotate freely due to the limitation of the V-shaped plate. During the positioning and clamping process, the auxiliary limitation of the V-shaped plate can provide stable support, which can reduce the error caused by the free rotation of the cylindrical workpiece, thereby ensuring the stability of the positioning and clamping. The positioning plate is driven to move in the direction close to the cylindrical workpiece by the connecting rod. The positioning plate moves to contact the cylindrical workpiece and squeezes the cylindrical workpiece to position it. Through pre-positioning, the position of the cylindrical workpiece can be effectively controlled by the positioning plate before milling, thereby avoiding dimensional errors or surface unevenness caused by position deviation.

[0016] (2) The motor shaft manufacturing automated milling processing equipment drives the anti-rotation plate to move downward by moving the anti-rotation frame downward. The anti-rotation plate moves downward to contact the columnar workpiece and assists in tightening the two sides of the columnar workpiece to prevent the columnar workpiece from rotating during milling. The anti-rotation plate moves downward and contacts the two sides of the columnar workpiece, which can effectively restrain the rotation of the columnar workpiece, thereby ensuring the stability of the columnar workpiece during the processing, thereby improving the smoothness of the processing process. The T-shaped plate generates vibration to drive the anti-rotation frame and the anti-rotation plate to resonate together. The vibration can effectively remove the waste chips inside the anti-rotation frame, thereby reducing the loosening of the anti-rotation plate caused by the waste chips, thereby ensuring the anti-rotation effect and accuracy of the anti-rotation plate.

[0017] (3) The motor shaft is manufactured in an automated milling processing equipment. The limit plate moves in a direction away from the fastening plate to drive the limit rod to move. The limit rod moves out of contact with the slide frame and releases the limit on the slide frame. Only after the limit on the slide frame is released can the lead screw be started to rotate to drive the slide frame to move in a direction close to the columnar workpiece. Only after it is detected that the columnar workpiece is firmly fixed by the anti-rotation plate can the limit on the slide frame be released and the milling operation be started. This can maintain stable contact between the columnar workpiece and the tool, further improving the milling processing accuracy and dimensional consistency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A No. 1 spring is arranged between the T-shaped plate 153 and the L-shaped frame 151, and the No. 1 spring can drive the T-shaped plate 153 to reset. The T-shaped plate 153 passes through the top of the L-shaped frame 151, and a rectangular frame 158 is fixedly installed on the circumferential surface of the U-shaped rod 152. The waste chips inside the anti-rotation frame 156 can be effectively removed through the vibration, thereby reducing the loosening of the anti-rotation plate 157 caused by the waste chips, thereby ensuring the anti-rotation effect and accuracy of the anti-rotation plate 157.

[0033] The rectangular frame 158 contacts the top of the T-shaped plate 153 , the anti-rotation plate 157 is elastic, and the anti-rotation plate 157 is made of rubber material with a large friction coefficient. The elasticity of the anti-rotation plate 157 can better limit the two sides of the columnar workpiece, and the arc panel 155 contacts the L-shaped plate 14 .

[0034] The protective device includes a hollow cylinder 161, a sliding rod 162, a limit frame 163, a curved tube 164, a limit plate 165, a limit rod 166 and a connecting ring 167.
