When the utility model is processed, it is only necessary to put the "worm wheel blank" into the vibrating plate of the automatic feeder, control the feeding speed by adjusting the amplitude of the vibrator, and send the workpiece to the pneumatic feeding mechanism through the slideway. At this time The pneumatic feeding mechanism then clamps the workpiece to the designated position, and the pneumatic clamping mechanism pushes the workpiece to the workpiece machine for clamping state, and the workpiece machine drives the workpiece to rotate. At this time, the hobbing mechanism moves to the working position under the control of the hydraulic lifting mechanism. Stop in the interval for gear hobbing work, and then return to the original position. At this time, the worm gear is processed, the pneumatic clamping mechanism returns, and then the pneumatic stripping mechanism operates to pull out the worm gear that has been processed and left on the workpiece machine and reset it, so that the machine repeats the above Action, the worm gears are processed one by one, so as to realize the full automation of worm gear hobbing. Therefore, the utility model has the characteristics of convenient use, simple operation, high production efficiency, reduced labor intensity, stable gear hobbing, accurate and reliable product positioning, and guaranteed product quality.
