Preferably: a ejector rod is installed in the middle of the right side of the pressing block, and the ejector rod can move left and right through the cylinder or servo electric cylinder, and further cooperate with the pressing block and the clamping base to clamp the workpiece, and There is a groove in the middle of the left side of the pressing block. The setting of the groove is better for chip removal and convenient for drilling.

Preferably: the front end of the gear is provided with a cover plate, the cover plate is fixedly installed on the upper front end of the clamping base, and lubricating oil can be provided inside the cover plate to reduce wear and prolong the maintenance cycle.

Compared with the prior art, the beneficial effect of the present invention is: firstly, the present invention places the hole-making system in a narrow space at the position to be processed, the clamping base and the clamping block perform the clamping operation on the workpiece, and then the main shaft starts, and the gear Combined transmission with rack and rack for feed movement. After the hole making is completed, the main shaft exits, and the feed direction is cleverly changed through the gear and rack to maximize the use of space and reduce the volume of the equipment; the system is small in size and very flexible. The hole making operation can be carried out in a small space. Compared with manual hole making, it can significantly improve the hole making efficiency and processing accuracy, especially the drilling of the joints of sheet metal materials in the aerospace field.
