Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0017] like Figure 1-3 As shown, a welding fixture for a backrest side panel assembly mainly consists of a fixture base 1, a mounting structure, and two welding clamping assemblies. Mounting structures for installation on a welding workstation are provided on both the left and right sides of the fixture base 1, enabling automated welding within the workstation and effectively reducing worker requirements. To facilitate component installation, welding clamping assemblies for welding the left and right backrest side panel assemblies are spaced apart on the fixture base 1, with the two welding clamping assemblies positioned opposite each other, allowing for welding of both backrest side panel assemblies in a single clamping operation.

[0018] The clamping assembly includes a mounting base plate 2 mounted on a fixture seat. A first clamping assembly for clamping first-order components and a second clamping assembly for clamping second-order components are arranged at intervals on the mounting base plate 2. The welding workstation enables welding of both first-order and second-order operations, eliminating the time required to change fixtures in between, thereby improving efficiency.

[0019] Specifically, the first clamping assembly includes a first support and positioning assembly and a first pressing assembly. The first support and positioning assembly includes a first support base 3 and a first positioning base 4, both mounted on the mounting base plate 2. A first support block 5 for supporting the core component is provided on the first support base 3. A first positioning pin 7 is provided on the first positioning base 4 via a first connecting block 6. At least two first positioning pins 7 are provided on the first positioning base 4. A first sensor 9 for detecting the placement of the corresponding component is provided on both the first support base 3 and the first positioning base 4 via a corresponding first sensor bracket 8. The first pressing assembly includes a first pressing cylinder 11 mounted on the mounting base plate 2 via a first pressing base 10. A first pressing block 12 is provided on the first pressing cylinder 11. The first pressing block 12 is used to cooperate with the first support block 5 and the first connecting block 6 to fix the corresponding component.

[0020] The second clamping assembly includes an intermediate telescopic support assembly, a second support positioning assembly, and a second clamping assembly. The second support positioning assembly includes a second support seat 13 and a second positioning seat 18, both mounted on the mounting base plate. A second support block 14 for supporting the corresponding component is provided on the second support seat 13. The intermediate telescopic support assembly includes a telescopic cylinder 16 mounted on the mounting base plate 2 via a telescopic seat 15. A telescopic block 17 is provided at the output end of the telescopic cylinder 16, and a second connecting block 19 is provided on both the telescopic block 17 and the second positioning seat 18. A second positioning pin 20 is provided on the second connecting block 19. A second sensor 29 for detecting the placement of the corresponding component is provided on both the telescopic block 17 and the mounting base plate 2 via a second sensor bracket 21. To provide support for the middle part of the backrest limiting bracket, an auxiliary support block 25 is also directly provided on the mounting base plate.

[0021] The second clamping assembly includes a second clamping cylinder 23 mounted on the mounting base plate 2 via a second clamping seat 22. A second clamping block 24 is mounted on the second clamping cylinder 23. The second clamping block 24 is used to cooperate with the second support block 14 and the second connecting block 19 to fix the corresponding components.

[0022] The mounting structure includes two connecting plates 26 respectively set on the left and right sides of the clamp base 1. Each connecting plate 26 is provided with a mounting plate 27. The mounting plate 27 is provided with a mounting positioning pin 28 for positioning and a fixing strip hole for fixing.

[0023] To further facilitate the installation between the fixture base and the welding worktable, a support plate is provided on the welding worktable at the position corresponding to the mounting plate. Baffles are provided on the front and rear sides of the support plate, and the distance between the two baffles is sufficient for the mounting plate to be inserted. Several ball bearings that contact the positioning plate are provided at intervals on the front and rear of the support plate, and the support plate is provided with mounting positioning holes for the installation positioning pin to be inserted.

[0024] During installation, place the mounting plate between the two baffles, with the mounting plate supported by the balls on the support plate. Then, fine-tune the mounting plate so that the mounting positioning pin can be inserted into the mounting positioning hole. Insert the mounting positioning pin and tighten the bolt passing through the mounting positioning hole to fix the fixture seat. Because the positioning plate is supported by the balls, a single person can easily move the entire welding fixture during fine-tuning, thereby reducing the time spent on fine-tuning, effectively improving welding efficiency and reducing the use of manpower.

[0025] Both the first and second support blocks are used to support the core connectors. Preferably, core positioning pins are provided on both the first and second support blocks. The first connecting block supports the mounting bracket, while the second connecting block and the auxiliary support block support the backrest limiting bracket.

[0026] To ensure accurate positioning, positioning holes and fixing holes are provided at the bottom of both the first and second positioning seats. Positioning pins that can be inserted into the mounting base plate are also provided in the positioning holes, so that the position can be accurately maintained after the positioning components are replaced.

[0027] The system includes two sensors, one for the first part and two for the second, used to detect whether the corresponding components are in place. During operation, the entire fixture is first installed on the welding workstation. Then, the core connector and the angle adjuster mounting bracket are placed in their corresponding positions. Once the first and second sensors detect signals, the first welding step begins. After welding is complete, the worker places the previously welded component and the backrest limiting bracket into the second clamping assembly. Simultaneously, the telescopic cylinder is activated. Once the first and second sensors detect signals, the second welding step begins. After welding is complete, the telescopic cylinder retracts, and the component is removed. In this two-step welding process, only the placement of the components needs to be changed, eliminating the need for intermediate component removal and reinstallation, thus effectively improving efficiency. Furthermore, the entire welding fixture is compatible with the welding workstation, eliminating manual welding and significantly reducing the demands on workers.
