[0024] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0025] like Figures 1 to 3 As shown in the figure, a vehicle frame welding device provided in this embodiment of the present invention includes a welding machine and a welding platform. The welding machine is not shown in the figure. The welding platform includes a base 1 and a clamp mounted on the base 1. The clamp includes two fixing units 2 and a connecting plate 3 connecting the two fixing units 2. One fixing unit 2 is higher than the other fixing unit 2, so as to be adapted to the front frame and rear frame of the chassis frame 16 respectively.

[0026] In addition, since the front frame is generally a forward-folding structure, the overall structure of the fixed unit 2 corresponding to the front frame will also be adapted to the shape of the front frame itself.

[0027] In this embodiment, the base 1 is a lifting base 1, which can be adjusted to a suitable height to facilitate manual welding work.

[0028] The fixing unit 2 includes a support frame 4 and multiple height adjustment components and fixing components installed on the support frame 4; the height adjustment components include a support frame 5 and a lifting component that drives the support frame 5 to move; the fixing components include a clamp 12 and a limiting component installed in the support frame 4.

[0029] The lifting assembly includes a support frame 5, a cam assembly 6, and a drive assembly. One end of the support frame 5 protrudes outside the support frame 4, and the other end is located inside the support frame 4. The cam assembly 6 is rotatably mounted inside the support frame 4. A second spring 7 is also provided inside the support frame 4. Under the action of the second spring 7, the support frame 5 abuts against the cam assembly 6. The drive assembly is used to drive the cam assembly 6 to rotate. Specifically, the drive assembly includes a rotating wheel 8. The central shaft of the rotating wheel 8 is connected to the cam assembly 6 in a transmission connection, that is, the central shaft of the rotating wheel 8 is splinedly connected to the central shaft of the cam assembly 6. The central shaft of the rotating wheel 8 is sleeved on the central shaft of the cam assembly 6. The central shaft of the rotating wheel 8 is rotatably connected to the support frame 4.

[0030] In addition, a locking structure for fixing the rotating wheel 8 should be provided on the support frame 4. The locking structure can be a fixing bolt. By tightening the fixing bolt that is threaded on the support frame 4, the end of the fixing bolt abuts against the rotating wheel 8 or its central shaft. The fixing bolt is not shown in the figure.

[0031] In some other embodiments, a single wheel 8 can drive the cam assemblies 6 of multiple lifting components to rotate synchronously. For example, the central shaft of the wheel 8 is directly connected to the central shaft of one of the cam assemblies 6, and the central shaft of the cam assembly 6 is connected to the central shafts of the other cam assemblies 6 through a belt drive structure / chain drive structure.

[0032] With the shape of the cam assembly 6, the support frame 5 can be raised and lowered during the rotation of the cam assembly 6;

[0033] To reduce wear and scratches on the frame 16, a rubber pad is installed on the top of the support frame 5;

[0034] The limiting component in this embodiment includes two limiting blocks 9 symmetrically arranged on the inner wall of the support frame 4. The clamp 12 has a U-shaped structure, and inclined sliders 13 are fixedly connected to both sides of the clamp 12 at positions opposite to the limiting blocks 9. A receiving groove 10 that cooperates with the limiting blocks 9 is opened on the inner wall of the support frame 4. A spring 11 connected to the limiting blocks 9 is installed in the receiving groove 10.

[0035] A limiting groove 15 is provided on the lower side of the limiting block 9. The limiting groove 15 is used to lock the clamp 12.

[0036] The support frame 4 is provided with a clearance groove 14 for the clamp 12 to make way, so that the support frame 4 has a certain degree of freedom of movement after being inserted into the clearance groove 14 and not locked by the limiting block 9.

[0037] Insert the clamp 12 into the support frame 4, and the inclined slider 13 abuts against the limiting block 9, causing the limiting block 9 to move toward the inner wall of the support frame 4. When the inclined slider 13 passes the limiting block 9, the limiting block 9 is reset under the action of the spring 11, and the inclined slider 13 is located directly below the limiting groove 15. At this time, rotate the wheel 8 to raise the support frame 5, pushing the frame 16 and the clamp 12 to rise synchronously until the inclined slider 13 enters the limiting groove 15, thus fixing the frame 16.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
