[0027] The turntable device 3 is driven to slide on the machine table 1 by the turntable motion device 6, and the sliding direction of the turntable device 3 is the same as the conveying direction of the automatic conveyor belt 5. The clamping fixture 2 is driven by the transverse movement of the turntable device 3 to transfer the workpiece to the processing equipment, and the sliding direction is consistent with the conveying direction, so that the processing equipment can be kept compact and the space occupied by the dynamic conveyor belt 5 can be reduced.
