The motor 21 is connected to an external power source through a wire, and the motor 21 drives the drill bit 22 to rotate to drill a hole in a workpiece 13. The first electric push rod 11 drives the push plate 6 to move horizontally, and when the push plate 6 moves, the motor 21 moves horizontally.

[0020] An adjustment structure is provided at the bottom of the driving disk 31, and the adjustment structure allows the push rod 7 to rotate around the center of the driving disk 31. The adjustment structure can lock the rotation angle of the push rod 7. The adjustment structure includes a reference rod 2 and an arc rod 8.

A positioning bolt 5 is inserted on the reference rod 2, and the positioning bolt 5 passes through one of the positioning holes 4.

[0021] After the push plate moves horizontally, it will push the push rod 7 to rotate, and the rotation of the push rod 7 will cause the driving disk 31 to rotate. By inserting the positioning bolt 5 into different positioning holes 4, the angle between the reference rod 2 and the push rod 7 can be adjusted, thereby adjusting according to the shape of the workpiece 2.

[0022] The inner side of the push rod 7 passes through the center of the driving disk 31, and the inner side of the push rod 7 is the side close to the end of the push plate 6. The connecting rod 39 passing through the base frame 1 is fixed with a support ring 17, and a turntable 16 is coaxially installed in the support ring 17. The bottom surface of the turntable 16 is coaxially connected to the top surface of the driving disk 31. The upper part of the turntable 16 is fixed with a workpiece 13 through a clamping mechanism.

The auxiliary positioning mechanism is used to press the workpiece 13 when drilling to reduce its shaking. When drilling, the pressing plate 24 contacts the workpiece 13 and presses the workpiece 13.

[0027] Working principle: first adjust the adjustment structure according to the shape of the workpiece 13. For example, if the workpiece 13 is a regular hexagonal column, the positioning bolt 5 is inserted into the corresponding positioning hole 4 so that the push rod 7 and the reference rod 2 form an angle of 60 degrees. Then, the second electric push rod 12 is started to adjust the height of the drill bit 22. Then, the first electric push rod 11 is started to extend. The first electric push rod 11 drives the push plate 6 to move horizontally. The push plate 6 contacts the push rod 7 and pushes the push rod 7 to rotate. The push rod 7 drives the drive disk 31 to rotate. The drive disk 31 rotates 60 degrees with the turntable 16 through the ratchet mechanism. Then, the drill bit 22 contacts the workpiece 13 for drilling. Then, the first electric push rod 11 is started to retract. Then, the push plate 6 stops contacting with the push rod 7. Under the action of the elastic reset structure, the drive disk 31 Back to the original position, due to the one-way transmission effect of the ratchet mechanism, the turntable 16 will not rotate, and the friction ring 18 keeps the turntable 16 in place, and then the first electric push rod 11 is started to extend, the first electric push rod 11 drives the push plate 6 to move horizontally, the push plate 6 contacts the push rod 7 and pushes the push rod 7 to rotate, the push rod 7 drives the drive disk 31 to rotate, and the drive disk 31 rotates 60 degrees with the turntable 16 through the ratchet mechanism, and then the drill bit 22 contacts the workpiece 13 for drilling, and then the first electric push rod 11 is started to retract... Repeat the above process to complete the drilling of the six faces of the workpiece 13. Assuming that the workpiece 13 is a regular pentagonal column, the positioning bolt 5 is inserted into the corresponding positioning hole 4 to make the push rod 7 and the reference rod 2 form an angle of 72 degrees.
