Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically a side welding beam positioning and assembly device. Background Technology

[0002] In the manufacturing process of side welded beams, the assembly and positioning of the side welded beams is a key link affecting the subsequent welding quality and processing efficiency. Traditional processing methods mostly rely on manual alignment and fixation using temporary shims and simple clamps. This not only suffers from low positioning accuracy, cumbersome operation, and low processing efficiency, but also makes it difficult to adapt to side welded beams of different lengths and specifications. Frequent adjustments to the positioning structure can easily lead to poor consistency in the processing of each workpiece, thereby increasing welding defects and rework costs. This cannot meet the requirements of modern steel structure processing for high-precision and high-efficiency positioning and assembly. Therefore, there is an urgent need for a side welded beam positioning and assembly device that can achieve multi-directional adjustment, precise positioning, and strong adaptability through multi-component collaboration to solve the shortcomings of traditional positioning methods.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Please see Figure 1 - Figure 4 A side-welded beam positioning assembly device, the first positioning component includes a first mounting plate 2, a lead screw 3, a transmission connecting block 4 and a first positioning plate 5. The first mounting plate 2 is provided at one end of the top of the tooling table 1. The first mounting plate 2 is provided with a mounting groove 201 on the side of the first mounting plate 2 near the tooling table 1. The lead screw 3 is provided in the mounting groove 201. The bottom of the lead screw 3 is rotatably connected to the bottom of the mounting groove 201. The top of the lead screw 3 passes through the top of the mounting groove 201 and is provided with a first handwheel 301. The transmission connecting block 4 is threadedly connected to the lead screw 3. The side of the transmission connecting block 4 near the tooling table 1 is fixedly connected to one side of the first positioning plate 5. The first positioning plate 5 is provided with multiple positioning holes 501 at both ends.

[0013] Through the above technical solution, rotating the first handwheel 301 drives the lead screw 3 to rotate, thereby driving the transmission connecting block 4 to move up and down along the lead screw 3, and simultaneously driving the first positioning plate 5 to adjust its height, so that the multiple positioning holes 501 at both ends of the first positioning plate 5 can be adapted to side welded beam workpieces with different heights and different positioning requirements.

[0014] This utility model provides a technical solution in which a first slider 601 is provided at the bottom of the mounting frame 6, and the mounting frame 6 is slidably connected to the slide groove 101 through the first slider 601. The lower end of the mounting frame 6 is set in the shape of "I". The upper end of the mounting frame 6 is provided with a movable groove 602. Both ends of the lower end of the mounting frame 6 are threadedly connected with screws 13. The two side walls of the upper end of the mounting frame 6 are threadedly connected with first threaded rods 7. One end of the first threaded rod 7 is fixedly connected to one side of the clamping block 8, and the other end of the first threaded rod 7 is provided with a second handwheel 701.

[0015] The above technical solution allows for flexible adjustment of the mounting bracket 6 on the tooling table 1 according to the length of the side-welded beam workpiece. Both ends of the mounting bracket 6 are threaded with screws 13. Rotating the screws 13 causes their lower ends to press against the top of the tooling table 1, achieving rapid fixation of the mounting bracket 6 after it slides into place, preventing it from shifting during subsequent positioning or welding. Rotating the second handwheel 701 drives the first threaded rod 7 to move the clamping block 8 horizontally, thereby laterally clamping and positioning the workpiece within the movable groove 602, ensuring that the workpiece does not shift laterally during subsequent processing.

[0016] This utility model provides a technical solution in which a mounting base 14 is provided at the top of the tooling table 1 away from the first mounting plate 2, and a second slider 1401 is provided at the bottom of the mounting base 14. The mounting base 14 is slidably connected to the slide groove 101 through the second slider 1401. Both ends of the top of the mounting base 14 are threaded with screws 13. A second mounting plate 1402 is provided between the screws 13 at the top of the mounting base 14. A third threaded rod 15 is threadedly connected to the middle of the second mounting plate 1402. Sliding rods 16 are slidably connected to the upper and lower sides of the third threaded rod 15 on the second mounting plate 1402. The end of the third threaded rod 15 near the tooling table 1 is rotatably connected to one side of the second positioning plate 17, and the end of the sliding rod 16 near the tooling table 1 is fixedly connected to one side of the second positioning plate 17.

[0017] Through the above technical solution, the position of the mounting base 14 can be flexibly adjusted according to the actual length of the side welded beam workpiece, effectively adapting to the positioning requirements of workpieces of different lengths. Both ends of the top of the mounting base 14 are threadedly connected to screws 13. Rotating the screws 13 allows their lower ends to press against the top of the tooling table 1, achieving rapid fixation of the mounting base 14 after it slides into place, preventing displacement of the mounting base 14 during subsequent positioning. Rotating the third threaded rod 15 drives the second positioning plate 17 to move closer to or further away from the workpiece, while the sliding rod 16 restricts the movement trajectory of the second positioning plate 17, preventing it from tilting, ultimately achieving precise positioning of the other end of the side welded beam workpiece.

[0018] This utility model provides a technical solution in which the top of one side wall of the movable groove 602 is fixedly connected to the bottom of the threaded connecting column 9. Two nuts 11 are threadedly connected to the threaded connecting column 9. The nuts 11 on the threaded connecting column 9 are rotatably connected to one end of the connecting rod 10. The middle of the other end of the connecting rod 10 is threadedly connected to the second threaded rod 12. A third handwheel 1201 is provided on the top of the second threaded rod 12.

[0019] Through the above technical solution, the height of one end of the connecting rod 10 clamped between the two nuts 11 can be fixed and adjusted by adjusting the position of the two nuts 11 on the threaded connecting column 9, thus meeting the top positioning requirements of workpieces of different heights. Simultaneously, the connecting rod 10 can be flexibly rotated according to the positioning position of the top of the workpiece, adjusting the orientation of its other end to adapt to the top positioning requirements of different parts of the workpiece. Furthermore, rotating the third handwheel 1201 drives the second threaded rod 12 to move up and down along the connecting rod 10, allowing the lower end of the second threaded rod 12 to abut against the top of the workpiece. Overall, this achieves auxiliary top positioning of the opposite side welding beam workpiece, forming a multi-directional positioning closed loop with lateral clamping and end-positioning, further preventing vertical displacement of the workpiece during assembly or welding, and significantly improving the comprehensiveness and stability of the positioning.

[0020] The working principle of this utility model is as follows: During operation, the workpiece is first placed in the movable slot 602 of the mounting bracket 6, with one end abutting against the first positioning plate 5. The first handwheel 301 is rotated to adjust the height of the first positioning plate 5 through the lead screw 3 and the transmission connecting block 4, so that the positioning hole 501 on it is aligned with the pre-machined hole of the workpiece to achieve initial positioning. Then, the first threaded rod 7 with the second handwheel 701 on the mounting bracket 6 is rotated to drive the clamping blocks 8 on both sides to clamp and position the workpiece from the side, and the screw 13 at the bottom of the mounting bracket 6 is tightened to fix it to the tooling table 1. Next, the mounting seat 14 is slid to a suitable position according to the length of the workpiece and locked by the screw 13 at its bottom. Finally, the third threaded rod 15 is rotated to push the second positioning plate 17, which works with the first positioning plate 5 to complete the final positioning and clamping of the other end of the workpiece, thereby achieving comprehensive and stable positioning and assembly of the workpiece.
