[0026] like Figures 1-4As shown, this utility model provides a welding fixture for a sunroof frame, including a workbench 1, a clamping assembly 2, a first driving device 3, a second driving device 4, and a third driving device 5; the output end of the first driving device 3 is fixedly connected to the bottom end of the second driving device 4, the top end of the second driving device 4 is fixedly connected to the bottom end of the third driving device 5, and is arranged perpendicularly to the third driving device 5; the top end of the third driving device 5 is fixedly connected to the rectangular workbench 1; the clamping assembly 2 is fixedly fixed to the workbench 1 by bolts, and the clamping assembly 2 includes a first clamping assembly 21 and a second clamping assembly 22. A first clamping assembly 21 is respectively provided at both ends of the workbench 1, and a second clamping assembly 22 is provided between the two first clamping assemblies 21; the workbench 1 is provided with a plurality of rectangular through holes for installing the first clamping assembly 21 and the second clamping assembly 22; the first clamping assembly 21 includes a first support frame 21, a first connecting plate 22, a first clamping member 23, and a first power member 24; the front end of the first connecting plate 22 is provided with a first support block 25, and the lower part of the rear end is connected to the first support frame 21. The frame 21 is connected by bolts, and its upper rear end is connected to the middle of the first clamping member 23 by a first pin. The first clamping member 23 has a first pressing block 26 at its front end and is connected to the first power member 24 at its rear end by a second pin.

The second clamping member 223 has a second pressing block 226 at its front end and its rear end connected to the second power member 224 by a fourth pin. The centers of the second pressing block 226 and the second support block 225 can be relatively perpendicular, and the second pressing block 226 and the second support block 225 can abut against each other. The second support block 225 and the second pressing block 226 are arranged opposite each other and are U-shaped structures.

[0027] In implementation, one first clamping assembly 21 is installed at each end of the rectangular worktable 1, and a second clamping assembly 22 is installed between the two first clamping assemblies 21. Based on the model of the part to be welded and the welding position, the positions of the first clamping assemblies 211 and 212 on the worktable 1 are adjusted. The cylinder transmission end of the first power component 214 is lowered, driving the first clamping component 213 to rise via the first and second pins, placing both ends of the part onto the first support block 215. The transmission end of the first power component 214 is then raised again, causing the first clamping component 213 to descend, thus pressing the part with the first clamping 26. Similarly, by controlling the second power component 224, the second support block 22... 5. The second clamping block 226 clamps the part at the middle position, fixing the part stably and ensuring welding quality. Depending on the size of the part, multiple sets of first clamping components 21 and second clamping components 22 can be set to ensure the stability of the part during the welding process and ensure welding quality. The clamping components have a simple structure, are easy to clamp and install, and are flexible in installation.

Threaded holes are provided on the surfaces of the guide slider 55 and the movable slider 53 for mounting the worktable 1. The top of the second driving device 4 is mounted on the bottom of the mounting platform 51. Figure 1 As shown, the first driving device 3 includes a base, with sliding sleeves at the four corners of the base, sliding rods inside the sliding sleeves, and a lifting cylinder in the middle of the base. The upper end of the sliding rod and the output end of the lifting cylinder are respectively fixedly connected to the bottom end of the second driving device 4.

[0029] During implementation, the threaded guide rod 54 is rotated by controlling the motor 56, thereby moving the guide slider 55, which in turn drives the worktable 1 to slide along the linear slide rail 52. Similarly, the second drive device 4 drives the third drive device 5 to slide along the same rail, enabling the worktable 1 to move in the X and Y directions, thus allowing adjustment of the X and Y positions between the part and the welding torch. The first drive device 3, by controlling the lifting cylinder, can drive the second drive device 4 to rise and fall, thereby driving the worktable 1 to rise and fall, thus enabling adjustment in the Y direction. The first drive device 3, the second drive device 4, and the third drive device 5 can quickly and accurately adjust the position between the part and the welding torch, improving welding efficiency and welding quality.

[0030] The working principle of a welding fixture for a sunroof frame: When using this welding fixture, one first clamping component 21 is installed at each end of the rectangular worktable 1 according to the model of the part to be welded and the welding position. A second clamping component 22 is installed between the two first clamping components 21. By instructing the first power component 214 and the second power component 224, the part is clamped and fixed. By setting the first drive device 3, the second drive device 4 and the third drive device 5, the welding position between the part and the welding gun is quickly and accurately adjusted, and then welding is performed. The fixture is easy to install and adjust, has high welding efficiency, and ensures welding quality.
