[0029] When processing the first mallet head 100, first place it in the placement groove 31, then manually hold the rocker of the main machine of the drilling machine 20 to lower the tap head 220 so that its bottom end faces the middle position to be processed on the top surface of the mallet head 100, then manually rotate the lateral adjustment screw 12 to press the elastic anti-skid layer 131 against the left end surface of the mallet head 100 to position the left end surface of the mallet head 100, then return the main machine to its original position, and push it through the push rod of the clamping cylinder 15, so that the mallet head 100 can be clamped between the elastic anti-skid layer 131 and the right anti-skid layer 161 to achieve clamping and fixing.

Then, the rotary motor runs in the reverse direction. At the same time, the rocker rotates in the reverse direction, so that the tap head 220 is removed from the mallet head 100 (this is an existing conventional operation and will not be described in detail here). All parts return to their positions, and the push rod of the pressing cylinder 15 retracts, so that the mallet head 100 can be disassembled. The processing depth has high precision, high accuracy and good effect.

It only needs to be placed in the placement groove 31 and pushed by the push rod of the clamping cylinder 15 to achieve clamping and fixing. Then, tapping processing can be performed, which has good effect and high efficiency.
