Technical Field
[0001] This utility model belongs to the field of vehicle frame welding tooling technology, and relates to a lightweight automated welding tooling for vehicle frames. Background Technology
[0002] Lightweight frames are a type of bicycle frame that uses special materials and designs to minimize weight while maintaining frame strength and rigidity. Their applications are wide-ranging, covering mountain bikes, heavy commercial vehicles, automobiles, motorcycles, and many other fields. Currently, welding fixtures are needed for stable support and fixation during frame welding. Frame welding fixtures fall under the category of welding fixtures, which are a general term for mechanical devices or equipment that play a coordinating and auxiliary role in the assembly and welding process of welded structures. Common welding fixtures include welding positioners, welding manipulators, welding roller frames, and welding clamps. Welding clamps are particularly common in frame welding. However, current welding clamp structures are relatively simple, typically using handles and pins for pressing and clamping, with a rubber top block at the top. Therefore, these clamps can only clamp and fix the frame at fixed points and cannot be adjusted according to different frame sizes, thus limiting their practicality. Utility Model Content
[0003] The purpose of this utility model is to address the above-mentioned problems by providing a lightweight automated welding fixture for vehicle frames, including a bracket with four casters fixedly mounted on it.

A second clamping mechanism is fixedly mounted on the other side of the first clamping mechanism, and a bracket is fixedly mounted on the other side of the second clamping mechanism and on the first support seat. Two sets of larger second clamping mechanisms are fixedly mounted at the center of the top of the bracket. A second support seat is fixedly mounted on the other side of the bracket, and a third clamping mechanism is fixedly mounted on the second support seat.
[0004] In the aforementioned lightweight vehicle frame automated welding tooling, the second clamping mechanism consists of a support plate, a slider, a limiting groove, a limiting rod, and a clamping assembly, wherein the bottom of the support plate is fixedly mounted on the top end face of the bracket by bolts.
[0005] In the aforementioned lightweight vehicle frame automated welding tooling, a main moving groove is provided through the support plate, and auxiliary moving grooves are provided on both sides of the main moving groove. A support screw is fixedly connected to the outer wall of one side of the slider, and a positioning block is fixedly connected to both sides of the support screw.
[0006] In the aforementioned lightweight vehicle frame automated welding tooling, the other end of the support screw passes through the main moving groove and is screwed with a clamping nut.

[0027] The present invention will be further described below with reference to the accompanying drawings.
[0028] like Figure 1-10 As shown, a lightweight vehicle frame automated welding tooling includes a bracket 1, on which four casters 2 are fixedly installed.

This not only provides stable support for the frame, but also allows for multi-angle clamping and fixing using the second clamping mechanism 5, making it more practical.
[0030] Combination Figure 1 , Figure 2As shown, the second clamping mechanism 5 consists of a support plate 51, a slider 52, a limiting groove 53, a limiting rod 54, and a pressing assembly 8, wherein the bottom of the support plate 51 is fixedly mounted on the top end face of the bracket 1 by bolts.
[0031] In this embodiment, by fixing the bottom of the support plate 51 to the bracket 1 with bolts, the support plate 51 can be stably installed on the bracket 1, and the position of the support plate 51 can be adjusted, thus making it more widely applicable.
[0032] Combination Figure 1 , Figure 2 and Figure 3 As shown, a main moving groove 55 is provided through the support plate 51, and auxiliary moving grooves 56 are provided on both sides of the main moving groove 55. A support screw 57 is fixedly connected to one side of the outer wall of the slider 52, and a positioning block 58 is fixedly connected to both sides of the support screw 57.
[0033] In this embodiment, a main moving groove 55 is provided on the support plate 51, and a secondary moving groove 56 is provided on both sides of the main moving groove 55, so that the support screw 57 and the positioning block 58 on the slider 52 can be slidably connected.
[0034] Combination Figure 1 , Figure 2 and Figure 3 As shown, the other end of the support screw 57 passes through the main moving groove 55 and is screwed to a clamping nut 507. The clamping nut 507 is attached to the outer wall of the support plate 51, while the positioning blocks 58 are slidably connected inside the secondary moving groove 56.
[0035] In this embodiment, by sliding the support screw 57 and the positioning block 58 in the main moving groove 55 and the auxiliary moving groove 56 respectively, the slider 52 can be adjusted up and down on the support plate 51, and then tightened and fixed by screwing the clamping nut 507.
[0036] Combination Figure 1 , Figure 3 and Figure 4 As shown, the slider 52 is a hollow block in which two circular metal pieces are fixedly connected by a fixing rod 59.

At the same time, a limiting groove 53 is provided on the corresponding other side of the sliders 52 to facilitate the adjustment of the angle of the pressing component 8.
[0038] Combination Figure 1 , Figure 5 As shown, the inner walls of the slider 52 are rotatably connected to the pressing assembly 8 via a pin 9. One end of the limiting rod 54 passes through the limiting groove 53 and the bottom of the pressing assembly 8, and is screwed to an adjusting nut 504. The adjusting nut 504 is attached to the outer wall of the slider 52.
[0039] In this embodiment, a pressing component 8 is rotatably connected to the inner wall of the slider 52 via a pin 9, so that the pressing component 8 can rotate at a certain angle within the slider 52. At the same time, the pressing component 8 is screwed into the limiting groove 53 via a limiting rod 54. This not only maintains the installation stability of the pressing component 8, but also allows it to be screwed in place by adjusting the nut 504.
[0040] Combination Figure 5 As shown, the clamping assembly 8 consists of a sleeve 81, a push rod 82, a handle 83, a spring 84, and a clamping block 85. Pins 9 are fixedly connected to the outer walls on both sides of the sleeve 81, and a push-pull groove 86 is provided on the top end face of the sleeve 81. Several U-shaped slots 87 are connected through one side of the push-pull groove 86.

In this way, the handle 83 can be used to push the push rod 82 to move inside the sleeve 81, thereby driving the clamping block 85 to move.
[0044] Combination Figure 5 , Figure 7 As shown, a spring 84 is fitted on the other end of the push rod 82, and a nut 88 is attached to the other end of the spring 84. The nut 88 is screwed onto the tail end of the push rod 82.
[0045] In this embodiment, by fitting a spring 84 on the other end of the push rod 82 and attaching a nut 88 to the other end of the spring 84, the push rod 82 can be quickly reset using the spring 84, and the moving distance of the push rod 82 can be adjusted using the nut 88.
[0046] Combination Figure 8 , Figure 9 and Figure 10 As shown, the clamping block 85 is an arc-shaped block with a magnetic structure. Both ends of the clamping block 85 are fitted with rubber anti-slip pads 10, and a rubber support pad 11 is pressed and connected to the inner wall of the clamping block 85 by screws.
[0047] In this embodiment, by setting the clamping block 85 as a magnetic arc-shaped block and covering both ends of the clamping block 85 with anti-slip pads 10, it can not only stably fit and connect the cylindrical frame, but also clamp and fix the square frame, and the stability during the clamping process is better.
