The loading rack 310 is vertically provided with a material discharge trough 320, and the workpiece 700 is adapted to be stacked in the material discharge trough 320. The moving table 200 drives the material discharge trough 320 of the loading mechanism 300 to approach the spindle chuck 100, and then the workpiece 700 is clamped by the spindle chuck 100. Then the moving table 200 drives the ejecting mechanism 500 to approach the workpiece 700 on the spindle chuck 100 and pushes the workpiece 700 into the spindle chuck 100, and then the workpiece 700 is fixed and clamped by the spindle chuck 100. Then the moving table 200 drives the turning mechanism 600 to approach the workpiece 700 clamped on the spindle chuck 100, and the workpiece 700 is turned under the drive of the moving table 200. Finally, the moving platform 200 drives the unloading mechanism 400 to approach the workpiece 700 after turning and remove the workpiece 700 to realize automated processing.

[0042] The CNC lathe workpiece processing device of the present invention utilizes the moving table 200 of the lathe itself, and the moving table 200 has high motion accuracy and good motion stability. It cooperates with the loading mechanism 300, the unloading mechanism 400, the lifting mechanism 500 and the turning mechanism 600 to realize automatic turning of the workpiece. There is no need to use a robot, and the structure is simple, which makes the manufacturing cost of the CNC lathe low. At the same time, maintenance and debugging are relatively simple, the failure rate is low, the operation stability is good, and the production efficiency is high.

[0043] In addition, the CNC lathe workpiece processing device of the present invention utilizes the moving platform 200 of the lathe itself, and there is no need to add a moving mechanism of the manipulator. The position accuracy is easy to control, debugging is easy, and the product processing accuracy is high.
