[0065] Working principle: During actual processing, the base frame can be turned over by rotating the oil cylinder, and then the workpiece table at the upper end can be turned forward, which makes it more convenient for the operator to clamp and fix the workpiece in the vise. After the workpiece is fixed, the workpiece table can be turned to a horizontal position by rotating the oil cylinder. In this way, the workpiece can be processed by the tool in the machining center. During the machining process, the workpiece table can be rotated by rotating the oil cylinder to adjust the processing angle of the workpiece. At the same time, a hydraulic cylinder can be set in the machining center to push the workpiece back and forth, which is very easy to use.
