[0033] Working principle: Multiple cylindrical workpieces to be processed are respectively mounted on the outer periphery of the cylindrical base 7 on different gear positioning structures.

When the transition chamfered portion of the square passive rod 16 contacts the inclined surface of the tapered sleeve 15, the tapered sleeve 15 drives multiple arc-shaped inner clamping plates 17 to move outward at the same time, and then the multiple arc-shaped inner clamping plates 17 simultaneously apply a clamping force to the inner wall of the cylindrical workpiece, thereby simultaneously achieving the clamping and fixation of the cylindrical workpieces to be processed with different inner diameters, and then the first servo reduction motor 9 is turned off. Afterwards, the position of the gear cutter 6 is fine-tuned by extending and retracting the electric push rod 3, and then the hydraulic cylinder 5 and the second servo reduction motor are turned on at the same time. The gear cutter 6 is driven to reciprocate up and down by the hydraulic cylinder 5, and in this process, the second servo reduction motor drives the fixed cylindrical workpiece to rotate slowly, so that the device can quickly fix multiple cylindrical workpieces in batches and cut the cylindrical workpieces into gear shapes, thereby completing the batch production and processing of gears, and improving the production and processing efficiency of gears.
