10. A drilling production method for a gear of an automobile gearbox, which is used for the drilling device for producing the gear of the automobile gearbox according to any one of claims 1 to 9 to realize the drilling production of the gear of the automobile gearbox, and the method comprises the following steps:

s101: firstly, a blank barrel (405) filled with blanks is arranged on a fixed seat (404), so that a notch (409) is flush with a feeding slide way (201);

s103: the device is started through an operation panel (3);

s105: the stroke cylinder II (401) drives the cylinder IV (402) to move to the lower part of the blank, and the cylinder IV (402) drives the rubber circular truncated cone II (403) to jack and penetrate into a process hole in the blank; then the stroke cylinder II (401) retracts, and the blank is conveyed to the position below the drill bit (604) from the inside of the blank barrel (405) through the notch (409) and the feeding slide way (201);

s107: the electric hydraulic cylinder (601) drives the machine head (603) to press downwards, the fork-shaped pressing block (605) drives the clamping block (701) to move towards the blank until the blank is clamped, meanwhile, the drill bit (604) performs drilling operation on the blank, and the drill bit (604) resets after the drilling is finished;
