Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to tooling fixtures, especially a water tank welding fixture. Background Technology

[0002] In the welding process of water tanks, existing technologies require manual adjustment of the fixture position, which is complicated and time-consuming. At the same time, due to inaccurate positioning or insecure fixing, deformation or misalignment is prone to occur during the welding process, affecting the welding quality and increasing the rework rate. Summary of the Invention

[0003] The purpose of this utility model is to provide a water tank welding fixture, which solves the technical problems of time-consuming and labor-intensive operation, inaccurate positioning, and unstable fixing in the existing water tank welding fixture.

[0004] This utility model discloses a water tank welding fixture, comprising a base plate. A first clamp, a second clamp, a third clamp, and a fourth clamp are evenly distributed circumferentially on the base plate. The first and second clamps are symmetrically arranged left and right, and the third and fourth clamps are symmetrically arranged front and back. Each of the first, second, third, and fourth clamps includes a first support and a second support mounted on the base plate. A lead screw is rotatably connected between the first and second supports. One end of the lead screw is connected to a handwheel. A slider is provided on the lead screw, and the slider has a threaded hole that mates with the lead screw. The slider and the base plate are parallel to the lead screw. The sliding pair along the rod axis has a slider connected to one end of a first connecting rod, the other end of the first connecting rod hinged to one end of a first universal ball joint, the other end of the first universal ball joint connected to a first clamping block, a second clamping block opposite to one side of the first clamping block, a second clamping block fixedly connected to one end of a second universal ball joint, the other end of the second universal ball joint hinged to one end of a second connecting rod, the other end of the second connecting rod connected to a driving device, the driving device fixed to the base plate by a mounting base, at least four flexible connecting rods connected to the base plate, and each flexible connecting rod connected to a welding torch.

[0005] Furthermore, the first connecting rod is L-shaped.

[0006] Furthermore, the driving device is a cylinder.

[0007] Furthermore, the axial direction of the lead screw of the first clamp is collinear with the axial direction of the lead screw of the second clamp and perpendicular to the axial direction of the lead screw of the third clamp.

[0008] Compared with existing technologies, this invention offers positive and significant advantages. A handwheel drives a lead screw to rotate, which in turn moves a slider. The slider, via a first connecting rod, moves a first clamping block. Simultaneously, a drive device, via a second connecting rod, moves a second clamping block, allowing the first and second clamping blocks to clamp the water tank workpiece. Multiple clamps can clamp multiple water tank workpieces. Adjusting the first and second universal ball joints allows for multi-angle clamping, adapting to water tanks of different specifications. This enables rapid positioning, improves positioning accuracy, and provides more secure fixation, ensuring stability during welding. It reduces the need for manual intervention, minimizes deformation or misalignment during welding, improves welding quality and efficiency, and reduces rework rates, making it suitable for automated welding applications in large-scale production. The flexible connecting rod 7 allows the welding torch 8 to perform multi-angle welding, facilitating welding operations. Attached Figure Description

Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0012] like Figure 1-Figure 2As shown, this utility model discloses a water tank welding fixture, including a base plate 6. A first clamp, a second clamp, a third clamp, and a fourth clamp are evenly distributed circumferentially on the base plate 6. The first and second clamps are symmetrically arranged left and right, and the third and fourth clamps are symmetrically arranged front and back. Each of the first, second, third, and fourth clamps includes a first support 10 and a second support 16 mounted on the base plate 6. A lead screw 5 is rotatably connected between the first support 10 and the second support 16. A handwheel 3 is connected to one end of the lead screw 5. A slider 4 is mounted on the lead screw 5, and the slider 4 has a threaded hole that mates with the lead screw 5. The slider 4 and the base plate 6 are parallel to the axial direction of the lead screw 5. The sliding pair has a slider 4 connected to one end of the first connecting rod 2. The other end of the first connecting rod 2 is hinged to one end of the first universal ball joint 11. The other end of the first universal ball joint 11 is connected to the first clamping block 1. A second clamping block 12 is arranged opposite to one side of the first clamping block 1. The second clamping block 12 is fixedly connected to one end of the second universal ball joint 13. The other end of the second universal ball joint 13 is hinged to one end of the second connecting rod 14. The other end of the second connecting rod 14 is connected to the driving device 9. The driving device 9 is fixed to the base plate 6 by the mounting base 15. At least four flexible connecting rods 7 are connected to the base plate 6. Each flexible connecting rod 7 is connected to a welding torch 8.

[0013] Furthermore, the first connecting rod 2 is L-shaped.

[0014] Furthermore, the driving device 9 is a cylinder.

[0015] Furthermore, the axial direction of the lead screw 5 of the first clamp is collinear with the axial direction of the lead screw 5 of the second clamp and perpendicular to the axial direction of the lead screw 5 of the third clamp.

[0016] Specifically, in this embodiment, the handwheel 3, lead screw 5, slider 4, universal ball joint, drive device 9, flexible connecting rod 7, cylinder, etc., all adopt well-known solutions in the prior art, which are already known to those skilled in the art, and will not be described in detail here.

[0017] The working principle of this embodiment is as follows: During operation, the handwheel 3 drives the lead screw 5 to rotate, which in turn drives the slider 4 to move. The slider 4, through the first connecting rod 2, drives the first clamping block 1 to move. Simultaneously, the drive device 9, through the second connecting rod 14, drives the second clamping block 12 to move, allowing the first clamping block 1 and the second clamping block 12 to cooperate in clamping the water tank workpiece. Multiple clamps clamp multiple water tank workpieces respectively. By adjusting the first universal ball joint 11 and the second universal ball joint 13, multi-angle clamping can be achieved, adapting to water tanks of different specifications, achieving rapid positioning, improving positioning accuracy, and ensuring more reliable fixation. This keeps the workpiece stable during welding, reducing the need for manual intervention and adjustment, minimizing deformation or misalignment during welding, improving welding quality and efficiency, reducing rework rates, and making it suitable for automated welding applications in large-scale production. The flexible connecting rod 7 allows the welding torch 8 to perform multi-angle welding, facilitating welding operations.
