Then the frame workpiece is placed on the tooling plate 10, and positioned by cylindrical pins and diamond pins, and the four cylinders 2 13 are started. The output ends of the four cylinders 2 13 drive the clamping members 15 to press up and down, and at the same time, the eccentric cam clamping members 16 are used to tighten and lock, thereby realizing the positioning of the frame workpiece. When lifting, start cylinder 1 6, and the output end of cylinder 1 6 retreats through the slider 5 and advances along the track groove 4, driving the pulley 3 to rotate and rise along the inclined surface of the slider 4.
