By effectively auxiliary fixing the workpiece 8, the position error caused by the change of the tilt angle can be avoided, thereby ensuring that the accuracy and position of the drilling meet the design requirements.

[0023] A No. 1 spring is arranged between the T-shaped rod 12 and the detection frame 13, and the No. 1 spring can drive the detection frame 13 to reset. The detection frame 13 runs through the left and right walls of the mobile frame 11, and a detection frame 16 is fixedly installed on the top of the right side of the mobile frame 11. A detection plate 17 is slidably installed on the inner wall of the detection frame 16, a detection rod 18 is fixedly installed on the top of the detection plate 17, and a button 19 is fixedly installed on the bottom of the detection frame 16. A clockwork spring is arranged between the pressing frame 15 and the U-shaped plate 14, and the pressing frame 15 can be reset by the clockwork spring. A dust collecting device 22 is arranged on the inner wall of the mobile frame 11, and the dust generated by drilling can be collected by the dust collecting device 22.

[0024] A No. 2 spring is arranged between the U-shaped plate 14 and the movable frame 11, and the No. 2 spring can drive the U-shaped plate 14 to reset. A No. 3 spring is arranged between the detection frame 16 and the detection plate 17, and the No. 3 spring can drive the detection plate 17 to reset. The detection rod 18 runs through the top of the detection frame 16, and the button 19 is electrically connected to the drilling equipment 3. The drilling equipment 3 can be driven to operate through the button 19. The top of the detection frame 13 is set as an inclined plane, and the position of the workpiece 8 is confirmed by the detection rod 18, so as to ensure that the workpiece 8 is fixed firmly during drilling, thereby reducing the risk of breakage or damage of the workpiece 8.

[0025] When this embodiment is working: after the workpiece 8 is placed on the top of the lifting plate 7, the servo motor 5 operates to drive the screw rod 6 to rotate, and the rotation of the screw rod 6 drives the lifting plate 7 to move upward, and the lifting plate 7 moves upward to drive the workpiece 8 to move upward.

The detection frame 13 is subjected to the reaction force of squeezing the workpiece 8 and moves to the right side. The detection frame 13 moves to the right side and is out of contact with the U-shaped plate 14.

The clockwork spring is squeezed by the pressing frame 15 and deformed. The pressing frame 15 cooperates with the elastic force of the clockwork spring to assist in fixing the top of the workpiece 8. If the position of the workpiece 8 is not accurate, the pressing frame 15 cannot fit and fix the workpiece 8 when it moves downward. The pressing frame 15 cannot fit and fix the workpiece 8, so that the U-shaped plate 14 cannot continue to move downward. After the position of the workpiece 8 is accurately adjusted, the pressing frame 15 can fit and fix the workpiece 8 so that the U-shaped plate 14 can continue to move downward. The U-shaped plate 14 continues to move downward and contacts the detection rod 18 and squeezes the detection rod 18. The detection rod 18 is squeezed and moved downward by the U-shaped plate 14. The detection rod 18 moves downward, driving the detection plate 17 to move downward. The detection plate 17 moves downward to press the button 19, and the button 19 is pressed by the detection plate 17 to drive the drilling equipment 3 to perform the drilling operation.
