Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-6 As shown, a side beam transverse drilling fixture includes a base 1, a movable seat 4, a drilling assembly, and a movable assembly. The movable assembly includes a guide rail 2, a slider 3, and a movable seat 4. Two symmetrical guide rails 2 are fixedly connected to the upper surface of the base 1. Four sliders 3 are fixedly connected to the lower surface of the movable seat 4 in pairs. The sliders 3 are slidably connected to the guide rails 2. A rack 5 is fixedly connected to the upper surface of the base 1. A movable motor 6 is fixedly connected to the movable seat 4 through a bracket.

[0026] A fixing frame 8 is fixedly connected to the upper surface of the movable base 4, and a drilling assembly is provided on the side wall of the fixing frame 8.

[0027] First, start the moving motor 6. The moving motor 6 drives the gear 7 to rotate. The gear 7 engages with the rack 5, causing the moving seat 4 to move and move the multi-axis drilling structure to the position on the side beam where drilling is required, and then drill the hole.

[0028] In one embodiment, the drilling assembly includes a lifting structure, a translation structure, and a multi-axis drilling structure. The lifting structure includes a lifting motor 9, a threaded rod 11, and a lifting plate 12. A guide rail 10 is fixedly connected to the side wall of the fixed frame 8. The threaded rod 11 is rotatably mounted on the inner wall of the guide rail 10 through a bearing seat. The lifting motor 9 is installed on the top wall of the guide rail 10. The output end of the lifting motor 9 is connected to the threaded rod 11. The lifting plate 12 is slidably connected to the inner wall of the guide rail 10. The lifting plate 12 is threadedly connected to the threaded rod 11.

[0029] Start the lifting motor 9, which drives the threaded rod 11 to rotate. The threaded rod 11 then drives the lifting plate 12 to rise and fall, which in turn drives the multi-axis drilling structure to rise and fall, further adjusting the drilling position of the multi-axis drilling structure for precise drilling.

[0030] In one embodiment, the translation structure includes a track plate 14, a sliding base 15, and a fixed base 16. The lifting plate 12 is provided with the track plate 14, and the track plate 14 is fixedly connected to the fixed base 16. The sliding base 15 is slidably connected to the inner side wall of the track of the track plate 14. A hydraulic cylinder 17 is installed on the sliding base 15, and the output end of the hydraulic cylinder 17 is connected to the fixed base 16. A fixed cylinder 18 is fixedly connected to the side wall of the sliding base 15, and a drive box 21 is fixedly connected to the side wall of the fixed cylinder 18. A drilling frame 19 is fixedly connected to the side wall of the drive box 21, and a multi-axis drilling structure is provided inside the drilling frame 19.

[0031] Start the hydraulic cylinder 17. The hydraulic cylinder 17 drives the sliding base 15 away from the fixed base 16, so that the rotating drill bits gradually approach the crossbeam of the carriage and simultaneously process multiple holes.

[0032] In one embodiment, the multi-axis drilling structure includes a drilling motor 13, a rotating shaft 20, and an adjusting guide rail 24. The rotating shaft 20 is connected to the inner wall of the fixed cylinder 18 via bearings. The drilling motor 13 is mounted on the sliding base 15 via a bracket. The output end of the drilling motor 13 is connected to the rotating shaft 20 via a synchronous belt drive. A gear 25 is fixedly connected to one end of the rotating shaft 20 located inside the drive housing 21. Four rotating shafts 27 are connected to the bottom wall of the drive housing 21 via bearings. Each rotating shaft 27 is fixedly connected to a gear. Gear 3 26 meshes with gear 2 25. A T-shaped slide rail 31 is provided on the lower surface of the drilling frame 19. Four sliding nuts 28 are slidably arranged in the track of the T-shaped slide rail 31. The four sliding nuts 28 cooperate with the fixing bolts 29 and the positioning nuts 30 respectively to fix the four adjusting guide rails 24. The T-shaped slide rail 31 has four nut placement holes 32. The adjusting guide rail 24 is connected to the drill rod 22 through the bearing. One end of the drill rod 22 is provided with a drill bit, and the other end is connected to the rotating shaft 27 through the universal joint 23.

[0033] First, start the drilling motor 13. The drilling motor 13 drives the rotating shaft 20 to rotate through the synchronous belt drive. The rotating shaft 20 drives the gear 25 to rotate. The gear 25 drives the four gears 26 to rotate. The gears 26 drive the rotating shaft 27 to rotate. The four rotating shafts 27 drive the four drill rods 22 to rotate through the universal joint 23 to perform multi-hole processing. The processing of multiple holes is completed at one time. Compared with drilling one hole at a time, the efficiency is greatly improved.

[0034] Since the adjusting guide rail 24 is installed with the drilling frame 19 through the sliding nut 28, fixing bolt 29, and positioning nut 30, and the drill rod 22 is connected to the rotating shaft 27 through the universal joint 23, the distance between multiple drill bits can be adjusted according to different drilling requirements. The sliding nut 28, fixing bolt 29, and positioning nut 30 can be loosened, the adjusting guide rail 24 can be moved, and then fixed. By installing the adjusting guide rail 24 at different positions below the drilling frame 19, the distance between multiple drill bits can be adjusted, which is simple and convenient.

[0035] In one embodiment, a waste hopper is mounted on the upper surface of the movable base 4 via a bracket, and the waste hopper is located below the drilling frame 19. Drilling waste is collected and processed centrally.

[0036] In one embodiment, the sidewalls of the drilling frame 19 are chamfered.

[0037] The above embodiments disclose a transverse drilling fixture for side beams, the specific working principle and process of which are as follows:

[0038] S1: First, start the moving motor 6. The moving motor 6 drives the gear 7 to rotate. The gear 7 engages with the rack 5, causing the moving seat 4 to move and move the multi-axis drilling structure to the position on the side beam where drilling is required, and then drill the hole.

[0039] S2: Start the lifting motor 9. The lifting motor 9 drives the threaded rod 11 to rotate, the threaded rod 11 drives the lifting plate 12 to rise and fall, and the lifting plate 12 drives the multi-axis drilling structure to rise and fall, further adjusting the drilling position of the multi-axis drilling structure for precise drilling.

[0040] S3: First, start the drilling motor 13. The drilling motor 13 drives the rotating shaft 20 to rotate through the synchronous belt drive. The rotating shaft 20 drives the gear 25 to rotate. The gear 25 drives the four gears 26 to rotate. The gears 26 drive the rotating shaft 27 to rotate. The four rotating shafts 27 drive the four drill rods 22 to rotate through the universal joint 23 to perform multi-hole processing. The processing of multiple holes is completed at one time. Compared with drilling one hole at a time, the efficiency is greatly improved.

[0041] Since the adjusting guide rail 24 and the drilling frame 19 are installed together by the sliding nut 28, the fixing bolt 29, and the positioning nut 30, and the drill rod 22 and the rotating shaft 27 are connected by the universal joint 23, the distance between multiple drill bits can be adjusted according to different drilling requirements. The sliding nut 28, the fixing bolt 29, and the positioning nut 30 can be loosened, the adjusting guide rail 24 can be moved, and then fixed. By installing the adjusting guide rail 24 at different positions under the drilling frame 19, the distance between multiple drill bits can be adjusted, which is simple and convenient.

[0042] S4: Start hydraulic cylinder 17. Hydraulic cylinder 17 drives sliding base 15 away from fixed base 16, so that multiple rotating drill bits gradually approach the crossbeam of the carriage and simultaneously process multiple holes.
