A rotatable pressure head is provided on the protruding end of the downward pressure cylinder 19. Under the clamping state, the workpiece can still rotate. The ejection cylinder 4 extends to drive the L-shaped support plate to extend. After pre-tightening, the screw moving slide 1 in the horizontal moving assembly 21 drives the positioning support plate assembly 22 to move to the right, and the L-shaped support plate 5 is pressed against the surface of the workpiece. After slightly pushing the workpiece, it retreats and goes down. The oil cylinder 19 is pressed tightly, and the ejection cylinder 8 in the position monitoring component 23 extends to drive the contact plate 9 to extend. At this time, the position on the grating ruler 13 is the origin position, and the screw moving slide 1 in the right side horizontal moving component 21 drives the contact plate 9 to contact the workpiece. At the moment of contact, the contact plate 9 moves and drives the grating ruler 13 to move, so that the contact position is detected. By calculating the encoded position of the screw moving slide 1 in the two groups of horizontal moving components 21 and the contact position detected by the grating ruler 13, the horizontal center position of the workpiece can be accurately calculated. After processing the two side surfaces, the workpiece can be directly rotated to continue processing.
