The workpiece is clamped on the clamping device, and the digital control system completes the automated processing of the workpiece according to the set program parameters. The machining center plays a very important role in parts processing.

[0003] In the related technology, application number CN112846900A discloses an automatic loading and unloading device on the side of a vertical machining center. The clamping part is placed in the blank receiving groove, and the driving cylinder is used to pull the flip plate to rotate so that the opening of the robot claw is aligned with a clamping part on the loading turntable. The robot claw clamps the workpiece to complete the loading. The loading turntable is driven to rotate by the loading rotating part in the device, so that the clamping part in the blank receiving groove on the loading turntable can be rotated to the side of the robot claw, which is convenient for the robot claw to grab.
