Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding fixture technology, and in particular to a self-positioning welding fixture. Background Technology
[0002] In industrial production, beams are crucial structural components, especially in the welding and manufacturing of beams, where precise positioning is key to achieving high-quality welding. The welding quality directly impacts the overall performance and safety of the product. Traditional beam welding fixtures widely employ inverted frame structures to achieve precise positioning. This structure, through a complex assembly process, precisely joins multiple components together to form a stable frame, thereby ensuring the beam's accurate positioning during the welding process.
[0003] However, the inverted frame structure has revealed some problems in practical applications, especially in loading and unloading. It often requires multiple steps, including placing the pallet inverted, pressing it with a clamping cylinder on the reverse side, supporting it with an internal support cylinder, flipping the fixture 180°, manually attaching the lateral limit block, and pushing it into place with a side-push cylinder. These steps are not only time-consuming and labor-intensive but also increase operational difficulty and labor costs. Similarly, the unloading process also requires flipping the fixture 180° and releasing the cylinder, further extending the production cycle.
[0004] To address the aforementioned issues, existing technologies attempt to improve the welding fixture for crossbeams. One approach involves using a clamping cylinder with lateral limiting mechanisms. This solution aims to prevent deformation of the crossbeam during welding by simultaneously clamping it vertically with the cylinder and limiting its horizontal movement. However, in practical applications, the clamping cylinder's horizontal limiting capability is limited and may not completely prevent horizontal deformation of the crossbeam during welding. Secondly, the crossbeam needs to be manually positioned before the cylinder presses down, and there are no effective limiting measures at this time. Therefore, the accuracy of the crossbeam's position cannot be guaranteed, and the clamping cylinder can easily scratch the crossbeam surface, affecting product quality. Utility Model Content

[0027] Please see Figures 1 to 5 The self-positioning welding fixture of this embodiment includes a frame 1, and a bearing plate 2 is partially disposed on the surface of the frame 1. The bearing plate 2 is provided with a first limiting component 3, a first pressing component 4, a second limiting component 5, and a second pressing component 6 that cooperate with each other. The first limiting component 3 and the first pressing component 4 achieve the positioning of the crossbeam on the pallet in this embodiment, while the second limiting component 5 and the second pressing component 6 achieve the positioning of the pallet in this embodiment.
[0028] Furthermore, in this embodiment, two first limiting components 3 are symmetrically arranged on both sides of the frame 1. Each first limiting component 3 includes a guide rail 31 and limiting members 32, with the limiting members 32 respectively disposed at both ends of the guide rail 31. The first limiting component 3 also includes a slider 33 and a connecting plate 34. The slider 33 is slidably disposed on the guide rail 31. The limiting members 32 limit the range of movement of the slider 33 along the guide rail 31. One end of the connecting plate 34 is connected to the slider 33, and the movement of the slider 33 causes the connecting plate 34 to move synchronously.
[0029] Furthermore, the first limiting component 3 also includes connecting members 35. Preferably, two connecting members 35 are provided on the adapter plate 34, and an adjusting part 36 is also provided on the connecting member 35. The adjusting part 36 is used to limit the lateral deformation of the crossbeam. The adjusting part 36 includes a first cylinder 361, a first push rod 362, and a first pressure rod 363. The first push rod 362 is telescopically fitted to the first cylinder 361, and the first pressure rod 363 is rotatably fitted to the first push rod 362. The adjusting part 36 also includes a first fixing member 364 and a first connecting rod 365. The first fixing member 364 is disposed on the first cylinder 361, and the two ends of the first connecting rod 365 are rotatably fitted to the first pressure rod 363 and the first fixing member 364, respectively. That is, when the first push rod 362 pushes the first pressure rod 363 to move, the accuracy of the first pressure rod 363 when pressing down is effectively ensured under the action of the first connecting rod 365.
[0030] Furthermore, in this embodiment, four first pressing components 4 are arranged. The first pressing components 4 are used to press the crossbeam onto the tray. Each first pressing component 4 includes a second cylinder 41, a first rotating shaft 42, a first rotating member 43, and a first fixed seat 44. The first fixed seat 44 is disposed on the support plate 2. The second cylinder 41 is connected to the first fixed seat 44. The first rotating shaft 42 is rotatably disposed on the second cylinder 41. The first rotating member 43 is connected to the first rotating shaft 42, and the first rotating member 43 is driven to move by the first rotating shaft 42. The first pressing component 4 also includes a second pressing rod 45. One end of the second pressing rod 45 is connected to the first rotating member 43, so that the second pressing rod 45 moves with the movement of the first rotating member 43. A snap-fit member 7 is also provided on the surface of the support plate 2. The second pressing rod 45 engages with the snap-fit member 7 in a first state. In this embodiment, the first state is the state when the second pressing rod 45 is pressing. Figure 3As shown, this ensures the stability of the second pressure rod 45 after clamping. Preferably, the second pressure rod 45 can also be configured to clamp the tray simultaneously, further improving the stability during welding.
[0031] Furthermore, in this embodiment, four second limiting components 5 are also provided. The second limiting components 5 have a structure similar to the first pressing component 4, and are used to laterally press the tray to fix it. The second limiting component 5 includes a second fixing seat 51, a third cylinder 52, and a second rotating shaft 53. The second fixing seat 51 is disposed on the bearing plate 2, the third cylinder 52 is connected to the second fixing seat 51, and the second rotating shaft 53 is rotatably disposed on the third cylinder 52. The second limiting component 5 also includes a second rotating member 54 and a third pressure rod 55. The second rotating member 54 is connected to the second rotating shaft 53, and one end of the third pressure rod 55 is also connected to the second rotating member 54. By rotating the second rotating shaft 53, the second rotating member 54 is driven to move, thereby causing the third pressure rod 55 to rotate to achieve pressing or releasing of the tray.
[0032] Furthermore, in this embodiment, ten second pressing components 6 are also provided. The second pressing components 6 are used to press the tray. The structure of the second pressing components 6 is similar to that of the adjustment part 36. The second pressing components 6 include a fourth cylinder 61, a second push rod 62, and a fourth pressure rod 63. The second push rod 62 is telescopically coupled to the fourth cylinder 61, and the fourth pressure rod 63 is rotatably coupled to the second push rod 62. That is, the movement of the second push rod 62 drives the movement of the fourth pressure rod 63. The second pressing components 6 also include a second fixing member 64 and a second connecting rod 65. The second fixing member 64 is disposed on the fourth cylinder 61, and the two ends of the second connecting rod 65 are rotatably coupled to the fourth pressure rod 63 and the second fixing member 64, respectively. When the fourth pressure rod 63 moves with the second push rod 62, the stability of the downward pressure of the fourth pressure rod 63 is ensured under the action of the second connecting rod 65.
[0033] Furthermore, each of the second clamping components 6 is provided with an adjusting block 8 for placing the pallet. The adjusting block 8 can be adaptively replaced according to the size of the pallet to achieve a good positioning effect. The tooling also includes a controller 9, which cooperates with the first limiting component 3, the first clamping component 4, the second limiting component 5, and the second clamping component 6 to realize the automatic positioning of the crossbeam and the pallet for welding.
[0034] The specific working process of the self-positioning welding fixture described in this embodiment of the present invention is described below:
[0035] First, place the tray on the frame 1, with the bottom of the tray contacting the adjusting block 8. Then, control the second pressing component 6 via the controller 9 to press and fix the tray, and then control the second limiting component 5 to laterally press the tray against the wall. Next, place the crossbeam in the corresponding position on the tray, and again control the first pressing component 4 via the controller 9 to press the crossbeam into the tray. Then, control the first limiting component 3 to restrict the lateral movement of the crossbeam. Welding between the crossbeam and the tray can then be achieved. After welding, the controller 9 sequentially opens and removes the first limiting component 3, the first pressing component 4, the second limiting component 5, and the second pressing component 6, repeating this process to achieve self-positioning welding.
[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
