[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes: a base plate 1, a lifting plate 2, a lifting structure 3, a bearing plate 4, and an adjusting structure 5.

Threaded holes are provided on the side surface of the translation slider 9, and the second lead screw 10 is threadedly connected to the threaded holes on the sliding side surface.

[0022] In the specific implementation process, two ear plates 11 are fixedly connected to the upper surface of one end of the base plate 1, and through holes are opened on the side surfaces of the two ear plates 11. A first connecting plate 12 is fixedly connected to the upper surface of the other end of the base plate 1.

[0023] The lifting plate 2 has a slide rail 13 fixedly connected to the lower surface of one end, and a sliding plate 14 slidably connected inside the slide rail 13. The lifting plate 2 has a second connecting plate 15 fixedly connected to the lower surface of the other end. The lifting plate 2 has two first fixing plates 16 and two second fixing plates 17 fixedly connected to the bottom of the mounting groove on the upper surface. The two first fixing plates 16 and two second fixing plates 17 have through holes on their side surfaces. The two first fixing plates 16 have a transmission rod 18 rotatably connected inside the through holes on their side surfaces. The transmission rod 18 has transmission bevel gears 19 fixedly connected to the outer surfaces of both ends. The transmission rod 18 has a first servo motor 20 at one end. The bottom of the first servo motor 20 is fixedly connected to the bottom of the mounting groove on the upper surface of the lifting plate 2. The power output end of the first servo motor 20 is fixedly connected to the end of the transmission rod 18 near the first servo motor 20. The first servo motor 20 is electrically connected to an external power source. When the first servo motor 20 is started, the power output end of the first servo motor 20 rotates and drives the transmission rod 18 to rotate.

[0024] The first support plate 33 and the second support plate 34 both have rotating grooves at their upper and lower ends. The upper rotating groove of the first support plate 33 is hinged to both ends of the sliding plate 14, and the lower rotating groove of the first support plate 33 is hinged to both ends of the first connecting plate 12. The upper rotating groove of the second support plate 34 is hinged to both ends of the second connecting plate 15. A push slider 21 is hinged inside the lower rotating groove of the second support plate 34. The side surface of the push slider 21 has through holes and threaded holes. A slide rod 22 is slidably connected inside the through holes on the side surface of the push slider 21. The two ends of the slide rod 22 are respectively fixedly connected to the opposite side of the two ear plates 11. A threaded rod 23 is threadedly connected inside the threaded holes on the side surface of the push slider 21. The two ends of the threaded rod 23 are respectively rotatably connected to the through holes on the side surfaces of the two ear plates 11. A drive servo motor 24 is provided at one end of the threaded rod 23, and the drive servo motor 24 outputs power. The end of the threaded rod 23 is fixedly connected to one end near the drive servo motor 24. The bottom of the drive servo motor 24 is fixedly connected to the upper surface of the base plate 1. The drive motor is electrically connected to an external power source. When the drive motor is started, the power output end of the drive motor rotates and drives the threaded rod 23 to rotate. When the threaded rod 23 rotates, it is threadedly connected to the threaded hole on the side surface of the push block. The push slider 21 can slide on the slide rod 22. Therefore, the rotation of the threaded rod 23 will cause the push slider 21 to move horizontally along the slide rod 22. The movement of the push slider 21 will push the lower end of the second support plate 34, causing the scissor structure composed of the first support plate 33 and the second support plate 34 to open or close. Since the upper ends of the first support plate 33 and the second support plate 34 are respectively connected to the lifting plate 2, this opening or closing action will drive the lifting plate 2 to move up and down, thereby adjusting the height of the lifting plate 2.

[0025] The upper surface of the translation plate 7 has a through hole on one end of the inner wall of the sliding groove. One end of the first lead screw 8 inside the threaded holes on both sides of the translation plate 7 is rotatably connected to the inner wall of the mounting groove on the upper surface of the lifting plate 2. The other end of the first lead screw 8 inside the threaded holes on both sides of the translation plate 7 is rotatably connected to the through holes on the side surfaces of the two second fixing plates 17. A driven bevel gear 25 is fixedly connected to one end of the first lead screw 8 inside the through holes on the side surfaces of the two second fixing plates 17. The first lead screw 8 inside the threaded holes on both sides of the translation slider 9... The driven bevel gears 25 at the ends mesh with the drive bevel gears 19 on the outer surfaces of the two ends of the transmission rod 18. The drive bevel gears 19 at both ends of the transmission rod 18 mesh with the driven bevel gears 25 on the first lead screw 8. Therefore, the rotation of the transmission rod 18 will drive the two first lead screws 8 to rotate synchronously. Since the two ends of the translation plate 7 are threadedly connected to the first lead screws 8, the rotation of the first lead screws 8 will cause the translation plate 7 to move laterally in the mounting groove of the lifting plate 2, thereby driving the bearing plate 4 and the steel structure body 31 on it to move laterally, so as to achieve precise adjustment of the lateral position.

[0026] The second lead screw 10 is rotatably connected at one end to the inner wall of the slide groove on the upper surface of the translation plate 7, and at the other end to the outer surface of the translation plate 7 through a through hole in the inner wall of the slide groove on the upper surface of the translation plate 7. The second lead screw 10 can rotate inside the through hole. A second servo motor 26 is provided at the end of the second lead screw 10 that extends to the outer surface of the translation plate 7. The bottom of the second servo motor 26 is fixedly connected to the upper surface of the translation plate 7, and the power output end of the second servo motor 26 is fixedly connected to the end of the second lead screw 10 located on the outer surface of the translation plate 7. The second servo motor 26 is electrically connected to an external power source. When the second servo motor 26 is started, the power output end of the second servo motor 26 rotates and drives the second lead screw 10 to rotate.

[0027] The lower surface of the support plate 4 is fixedly connected to the upper surface of the translation slider 9. When the translation slider 9 slides, it can drive the support plate 4 to move. A fixing plate 27 is fixedly connected to the upper surface of the support plate 4. A threaded hole is opened on the side surface of the fixing plate 27. A screw 28 is threadedly connected inside the threaded hole on the side surface of the fixing plate 27. A rotating wheel 29 is fixedly connected to one end of the screw 28. The rotating wheel 29 makes it convenient for the operator to hold and rotate the screw 28. A clamping plate 30 is rotatably connected to the other end of the screw 28. The lower surface of the clamping plate 30 is slidably connected to... A steel structure body 31 is attached to the upper surface of the bearing plate 4. The clamping plate 30 is provided on one side. The steel structure body 31 is located below the drill bit of the drilling machine body 6. A limit plate 32 is provided on the side of the steel structure body 31 away from the clamping plate 30. The lower surface of the limit plate 32 is fixedly connected to the upper surface of the bearing plate 4. Rotating the rotating wheel 29 drives the screw 28 to rotate, which drives the clamping plate 30 to move horizontally. The limit plate 32 clamps and fixes the steel structure body 31 on the bearing plate 4 to prevent shaking during drilling and ensure processing accuracy.

[0028] The working principle of this utility model is as follows: The steel structure body 31 to be processed is placed on the bearing plate 4, with one side pressed against the limiting plate 32 to complete the initial positioning. Then, the rotating wheel 29 is rotated, causing the screw 28 to rotate and drive the clamping plate 30 to move towards the steel structure body 31 until it is firmly clamped to prevent shaking during the drilling process. The drive servo motor 24 is started, which drives the threaded rod 23 to rotate. Since the push slider 21 is threadedly connected to the threaded rod 23, and the push slider 21 can slide on the slide rod 22, the rotation of the threaded rod 23 will cause the push slider 21 to move along the slide rod 22. 2. Horizontal movement of the slider 21 pushes the lower end of the second support plate 34, causing the scissor-like structure formed by the first support plate 33 and the second support plate 34 to open or close. Since the upper ends of the first support plate 33 and the second support plate 34 are respectively connected to the lifting plate 2, this opening or closing action will drive the lifting plate 2 to move up and down, thereby adjusting the height of the lifting plate 2 to adapt to the thickness of the steel structure body 31, ensuring that the drill bit can accurately contact the position to be drilled. The first servo motor 20 is started, which drives the transmission rod 18 to rotate. The transmission bevel gears 19 at both ends of the transmission rod 18... The driven bevel gear 25 on the first lead screw 8 meshes with the driven bevel gear 25, so the rotation of the transmission rod 18 will drive the two first lead screws 8 to rotate synchronously. Since the two ends of the translation plate 7 are threadedly connected to the first lead screws 8, the rotation of the first lead screws 8 will cause the translation plate 7 to move laterally in the mounting groove of the lifting plate 2, thereby driving the bearing plate 4 and the steel structure body 31 on it to move laterally, realizing precise adjustment of the lateral position. The second servo motor 26 is started, which drives the second lead screw 10 to rotate. The translation slider 9 is threadedly connected to the second lead screw 10, and the translation slider 9 can slide in the groove of the translation plate 7, so the first lead screw 10 can rotate. The rotation of the second lead screw 10 causes the translation slider 9 to move longitudinally along the groove of the translation plate 7, thereby driving the bearing plate 4 and the steel structure body 31 on it to move longitudinally, achieving precise adjustment of the longitudinal position. After adjusting the height of the lifting plate 2 and the horizontal position of the steel structure body 31, the drilling machine body 6 is turned on, and the drill bit begins to rotate and drill holes in the steel structure body 31. During the drilling process, since the positions of the lifting plate 2 and the bearing plate 4 have been precisely adjusted, and the steel structure body 31 is firmly clamped, the accuracy and quality of the drilling can be guaranteed. After drilling is completed, the drilling machine body 6 is turned off. The rotating wheel 29 is reversed, causing the clamping plate 30 to release the steel structure body 31, and the processed steel structure is taken out. If other steel structures need to be processed, the above steps can be repeated.

[0029] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
