[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a welding fixture for automobiles that is easy to disassemble and maintain, including a support platform 1, a mounting groove 4 opened on the upper part of the support platform 1, a U-shaped seat 2 placed inside the mounting groove 4, and a connecting component 3 arranged on the upper part of the support platform 1. The connecting component 3 includes a disassembly and assembly mechanism 31 arranged on the upper part of the support platform 1. An adjustment mechanism 32 is arranged on the upper part of the support platform 1. The disassembly and assembly mechanism 31 includes an inner groove 311 opened inside the support platform 1. A movable block 312 is slidably connected to the inner wall of the inner groove 311. A sloping block 313 is fixedly connected to the side of the movable block 312 away from the sloping block 313. A connecting rod 314 is fixedly connected to the inner wall of the inner groove 311. A first spring 315 is fixedly connected to the inner wall of the inner groove 311. A limit block 316 is fixedly connected to the outer end of the connecting rod 314. A pull rod 317 is fixedly connected to the outer side of the limit block 316. A slot 318 is opened on the side wall of the U-shaped seat 2. A pressing column 319 is movably connected to the bottom of the support platform 1. A connecting frame 3110 is fixedly connected to the bottom end of the pressing column 319. A second spring 3111 is fixedly connected to the upper part of the connecting frame 3110.

[0028] In this embodiment, one end of the first spring 315 is fixedly connected to the movable block 312, the inclined plate block 313 is movably inserted through the mounting groove 4 and engaged with the slot 318, and the outer end of the connecting rod 314 is movably connected to the support platform 1. Through the cooperation of the inner groove 311, the movable block 312, the inclined plate block 313, the connecting rod 314, the first spring 315, the limiting block 316, the pull rod 317, the slot 318, the pressing column 319, the connecting frame 3110, and the second spring 3111, it is convenient for manual disassembly and assembly of the U-shaped seat 2, thereby facilitating manual inspection and maintenance of the limiting components of the electric telescopic rod 326 and the limiting plate 327. When the inclined plate block 313 separates from the slot 318, the second spring 3111 can spring the U-shaped seat 2 upward under the action of elasticity, which makes it even more convenient for manual disassembly of the U-shaped seat 2.

[0029] Furthermore, the top end of the second spring 3111 is fixedly connected to the bottom of the support platform 1, and the second spring 3111 is sleeved on the outside of the pressure post 319.

[0030] When using this device, if it is necessary to disassemble the U-shaped seat 2, simply hold the pull rod 317 to move the limiting block 316 outward. This will cause the connecting rod 314, which is fixedly connected to the inner side of the limiting block 316, to move the movable block 312 outward synchronously. This will allow the inclined locking block 313, which is fixedly connected to one side of the movable block 312, to separate from the locking groove 318. Subsequently, under the action of the elastic force of the second spring 3111, the connecting frame 3110 will move the pressing column 319 upward. This allows the U-shaped seat 2 to be pressed upwards, causing the slot 318 on the side wall of the U-shaped seat 2 to misalign with the inclined block 313. Then, the pull rod 317 can be released manually, freeing up the operator's hands and eliminating the need for continuous support. The U-shaped seat 2 can then be removed upwards without requiring excessive manual operation, increasing the applicability of the device. By disassembling the U-shaped seat 2, it is convenient for manual inspection and maintenance of the limiting components such as the electric telescopic rod 326 and the limiting plate 327 located inside the U-shaped seat 2.

[0031] Example 2

[0032] Based on Embodiment 1, a preferred embodiment of the automotive welding fixture provided by this utility model, which is easy to disassemble and maintain, is as follows: Figures 1 to 5 As shown: The adjustment mechanism 32 includes a motor 321 fixedly mounted on the upper part of the U-shaped seat 2 via a mounting bracket. A lead screw 322 is fixedly connected to the output end of the motor 321. A first sliding groove 323 is provided on the inner wall of the U-shaped seat 2. A first slider 324 is slidably connected to the inner wall of the first sliding groove 323. A mounting plate 325 is fixedly connected to the outer side of the first slider 324. An electric telescopic rod 326 is fixedly mounted on the outer wall of the mounting plate 325. A limit plate 327 is fixedly connected to the output end of the electric telescopic rod 326. A second sliding groove 328 is provided on the inner wall of the U-shaped seat 2. A slide rod 329 is fixedly connected to the inner wall of the second sliding groove 328. A second slider 3210 is slidably connected to the outer wall of the slide rod 329.

[0033] In this embodiment, the lead screw 322 is rotatably connected to the U-shaped seat 2 via a bearing, and the first slider 324 is threadedly connected to the outer wall of the lead screw 322. Through the cooperation of the motor 321, the lead screw 322, the first slide groove 323, the first slider 324, the mounting plate 325, the electric telescopic rod 326, the limiting plate 327, the second slide groove 328, the slide rod 329, and the second slider 3210, the height of the limiting plate 327 can be adjusted, thereby enabling the fixing of automotive parts of different heights and increasing the applicability of the device.

[0034] Furthermore, the outer side of the second slider 3210 is fixedly connected to the mounting plate 325.

[0035] When fixing automotive parts, the workpiece is first placed manually on the upper part of the U-shaped seat 2. Then, the motor 321 drives the lead screw 322 to rotate, which causes the first slider 324, threaded to the outer wall of the lead screw 322, to move the mounting plate 325. This causes the electric telescopic rod 326, which is fixedly installed on one side of the mounting plate 325, to move the limiting plate 327 synchronously. The height of the limiting plate 327 can then be adjusted. Under the action of the sliding rod 329 and the second slider 3210, the connection between the mounting plate 325 and the U-shaped seat 2 is strengthened, thereby reducing the wear between the first slider 324 and the lead screw 322 and extending the service life of the parts. By adjusting the height of the limiting plate 327, workpieces of different heights can be clamped and fixed. When the limiting plate 327 is adjusted to a suitable height, the electric telescopic rod 326 drives the limiting plate 327 to move towards the workpiece, thus clamping and fixing the workpiece.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
