[0003] As a crucial component of wheelchairs, wheelchair frames are often connected and secured by welding to ensure strength and stability during use. During the welding process, some components require manual welding. To ensure stability, universal clamping assemblies are used to secure the wheelchair frame components. However, these universal welding clamping assemblies are often large for ease of use, requiring manual holding of the components during welding, making the process cumbersome. Furthermore, the welding angles of components vary, and existing clamping assemblies cannot meet diverse welding needs. This necessitates replacing the clamping assemblies with suitable ones for each component welding, resulting in low applicability of the clamping assemblies.

A first C-shaped clamping block 9 and a second C-shaped clamping block 10 are rotatably connected to the upper outer surfaces of the two height adjustment blocks 6, respectively. An arc-shaped slot 11 is provided through one side of both the first C-shaped clamping block 9 and the second C-shaped clamping block 10. A transverse arc-shaped slot 12 is provided on one side surface of the first C-shaped clamping block 9. A fixing screw hole 13 is provided through the upper surface of both the first C-shaped clamping block 9 and the second C-shaped clamping block 10. A fixing bolt 14 is threadedly connected inside the fixing screw hole 13.

[0020] The two rotating holes 201 are vertically set, and the outer ends of the two screws 3 extend out of the outer surface of the processing platform 2. A handle is installed on the outer end of the processing platform 2.

[0021] The protrusion 4 slides inside the rotating hole 201. The inner wall of the rotating hole 201 is provided with a sliding groove 202, and the protruding part of the protrusion 4 is inserted into the sliding groove 202.

[0022] The lower end of the height adjustment block 6 is located above the processing platform 2. The outer surface of the height adjustment block 6 is in close contact with the inner wall of the square storage block 5. A height limiting screw 7 is provided through the upper half of the outer surface of the square storage block 5. The height limiting screw 7 is located near the opening of the square storage block 5.

[0023] The height limiting screw 7 is internally threaded with a height limiting bolt 8. When the height adjusting block 6 is fixed, the inner end of the height limiting bolt 8 is tightly fitted with the outer surface of the height adjusting block 6.

[0024] The arc-shaped slot 11 and the transverse arc-shaped slot 12 are both located inside the lower half of the first C-shaped clamping block 9 and the second C-shaped clamping block 10. During welding, the frame components are placed inside the arc-shaped slot 11 and the transverse arc-shaped slot 12, and the inner end of the fixing bolt 14 is tightly fitted with the outer surface of the frame components.

[0025] The inner end surfaces of the first C-shaped clamping block 9 and the second C-shaped clamping block 10 are each equipped with a rotating column 15. A limit hole is opened through the upper half of the outer surface of the height adjustment block 6. The rotating column 15 is rotatably disposed inside the limit hole, and the outer surface of the rotating column 15 is tightly fitted with the inner wall of the limit hole.

[0026] An angle fixing bolt 16 is threadedly connected inside the limiting hole, and the front half of the angle fixing bolt 16 is threadedly connected to the rotating column 15.

[0027] When welding metal components of the vehicle frame, the two metal components to be welded must first be fixed. The metal components can be initially positioned by the arc-shaped grooves 11 on the first C-shaped clamping block 9 and the second C-shaped clamping block 10. During this process, in order to ensure that the components are firmly fixed inside the arc-shaped grooves 11, a fixing bolt 14 that can move up and down is provided. The fixing bolt 14 is connected to the fixing screw hole 13 by thread. When the fixing bolt 14 is rotated, the inner end of the fixing bolt 14 is pushed inward until the inner end of the fixing bolt 14 exerts a squeezing effect on the metal component, thus completing the fixing of the metal component. Then, based on the length of the component, the distance between the first C-shaped clamping block 9 and the second C-shaped clamping block 10 is adjusted. If the component on the first C-shaped clamping block 9 is placed vertically, it is necessary to ensure that the protrusion 4 below the second C-shaped clamping block 10 is located at the innermost end of the rotating hole 201. At this time, the second C-shaped clamping block 10 and the first C-shaped clamping block 9 are horizontally spaced apart. Then, the screw 3 below the first C-shaped clamping block 9 is rotated. Based on the threaded connection between the screw 3 and the protrusion 4, the screw 3 drives the protrusion 4 towards the second C-shaped clamping block 10. 0. Move to one side to initially position the connection part of the component. If the component on the first C-shaped clamping block 9 is placed horizontally, the positions of the first C-shaped clamping block 9 and the second C-shaped clamping block 10 need to be moved horizontally simultaneously. With the connection between the screw 3 and the protrusion 4, the positions of the first C-shaped clamping block 9 and the second C-shaped clamping block 10 can be adjusted and locked. Components of different lengths can be welded. At the same time, the stability of the component during the welding process can be ensured, and the horizontal movement of the component during the welding process can be avoided. After the welding positions of the two components are initially fixed, the welding angle and height of the components need to be adjusted. During this process, the height adjustment block 6 is pulled upwards according to the welding position until it is adjusted to a suitable position. In order to ensure the stability of the height position of the first C-shaped clamping block 9 and the second C-shaped clamping block 10, a height limiting screw 7 and a height limiting bolt 8 are set at the connection between the height adjustment block 6 and the square storage block 5. By rotating the height limiting bolt 8, based on the threaded connection, the inner end of the height limiting bolt 8 exerts a squeezing effect on the height adjustment block 6, thereby fixing the position of the height adjustment block 6. If the two components need to be adjusted, the height adjustment block 6 can be adjusted accordingly. By connecting at a certain angle, the welding angle of the component can be adjusted based on the rotatable connection between the first C-shaped clamping block 9 and the second C-shaped clamping block 10 and the height adjustment block 6. In this process, in order to ensure the stability of the component after the angle adjustment, the height limiting screw cylinder 7 and the height adjustment block 6 are connected and fixed by setting the rotating column 15 and the angle fixing bolt 16. By rotating the angle fixing bolt 16, the front half of the angle fixing bolt 16 is connected to the rotating column 15. Based on the fact that the angle fixing bolt 16 is also threadedly connected to the limiting hole, the stability of the first C-shaped clamping block 9 and the second C-shaped clamping block 10 after the angle adjustment can be guaranteed. First, it can clamp and fix parts of different specifications. During the welding process, there is no need to manually press the parts to assist welding, which facilitates welding and further ensures the stability of the parts during the welding process. Second, it can meet the welding requirements of different angles and heights. When welding parts of different angles and heights, there is no need to change different welding fixtures, which further improves the applicability of the device.
