For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0019] As shown in the accompanying drawings, the utility model includes a welding table 1 and a welding plate positioning and clamping assembly. The welding table 1 is provided with an expansion shaft 2. The welding plate positioning and clamping assembly includes an arc guide rail 3 and a pair of support arms 4. The arc guide rail 3 is coaxially installed on the expansion shaft 2 through a pair of support arms 4. A group of adjustment sliders 5 are provided on the arc guide rail 3, and a welding plate positioning fixture 6 is provided on the adjustment slider 5.

[0020] The expansion shaft 2 in this case is a mechanical expansion shaft, which is adjusted by rotating the handle to perform tightening or loosening. When in use, first install the hub sleeve on the expansion shaft 2, and the expansion element of the expansion shaft 2 is stretched to fix the hub. Then, the welding plate positioning clamping assembly is installed at the end of the expansion shaft 2, and the position of the welding plate positioning fixture 6 is adjusted. The welding plate is clamped and aligned with the repair position of the hub through a set of adjustable welding plate positioning fixtures 6. After fixing, the weld is welded.

[0021] The arc guide rail 3 is a semicircular structure and is arranged coaxially with the expansion shaft 2. The adjusting slider 5 can slide on the arc guide rail 3. The adjusting slider 5 is provided with a fastening screw. After the position of the adjusting slider 5 is adjusted, it is fixed by the fastening screw.

[0022] Furthermore, a connecting sleeve 9 is provided at one end of the support arm 4, and the two connecting sleeves 9 are movably connected by a shaft sleeve 10, and the shaft sleeve 10 is movably sleeved on the expansion shaft 2. The other end of the support arm 4 is adjustably mounted on the arc guide rail 3 through a connecting slider 11, and a positioning locking sleeve 12 is screwed on the expansion shaft 2 for limiting the axial position of the two connecting sleeves 9.

[0023] The two connecting sleeves 9 are both sleeved on the shaft sleeve 10 to form an integral sleeve mounted on the expansion shaft 2. The connecting sleeve 9 can rotate on the shaft sleeve 10 to adjust the angle at which the two support arms 4 are opened. After installation, the two support arms 4 are located on the same plane. The connecting slider 11 can slide on the arc guide rail 3. A fastening screw is provided on one side of the connecting slider 11 to fix the position of the connecting slider 11. After the welding plate positioning clamping assembly is installed on the expansion shaft 2, the positioning locking sleeve 12 positions the welding plate positioning clamping assembly from one side, that is, one side of the welding plate positioning clamping assembly is attached to the wheel hub, and the other side of the welding plate positioning clamping assembly is fixed by the positioning locking sleeve 12. In this case, the end of the expansion shaft 2 is provided with an external thread, and the positioning locking sleeve 12 is provided with an internal thread.

[0024] The expansion shaft 2 is provided with a positioning guide groove, and the sleeve 10 is equipped with a positioning block that mates with the guide groove. This means that the sleeve 10 is fixed to the end of the expansion shaft 2 and cannot rotate. In this case, both the sleeve 10 and the positioning and locking sleeve 12 are installed at the end of the expansion shaft 2, i.e., at a location where there are no expansion elements.

[0025] One end of the sleeve 10 is provided with an outwardly bent protrusion for limiting the inner connecting sleeve 9, while the positioning locking sleeve 12 applies pressure to the connecting sleeve 9 from the outside, and cooperates with the sleeve 10 to clamp the two connecting sleeves 9 from both inside and outside.

[0026] When the welding plate positioning clamping assembly is fixed, one of the welding plate positioning clamps 6 can be adjusted to clamp it on the outer ring of the wheel hub for greater stability.

[0027] Furthermore, a sliding adjustment block 13 is provided on one side of the support arm 4 , and a limiting guide roller 14 is provided on the sliding adjustment block 13 .

[0028] The limiting guide roller 14 is used to fit on the outside of the outer ring of the wheel hub to facilitate the adjustment of the overall position of the welding plate positioning and clamping assembly. The sliding adjustment block 13 can slide up and down on the support arm 4 to adjust the height of the limiting guide roller 14 according to the size of the wheel hub.

[0029] Furthermore, an adjusting rod 16 is provided on the adjusting slider 5, and the welding plate positioning fixture 6 is fixed on the adjusting rod 16. The adjusting rod 16 is used to adjust the vertical position of the welding plate positioning fixture 6, and a fastening screw is provided on one side of the adjusting slider 5 for fixing the position of the adjusting rod 16.

[0030] The adjusting slider 5 is provided with a positioning guide block, and the adjusting rod 16 is provided with a positioning guide groove that cooperates with the positioning guide block. The adjusting rod 16 is movably plugged into the adjusting slider 5 and can only move up and down but not rotate to ensure that the welding plate positioning fixture 6 remains parallel to the side of the wheel hub.

[0031] Preferably, the welding plate positioning fixture 6 includes a U-shaped fixture seat 17 , and a locking screw 18 is provided on one side of the U-shaped fixture seat 17 .

[0032] In this case, the locking screw 18 is the movable part, and the inner plate of the U-shaped clamp seat 17 on the opposite side of the locking screw 18 is in the same plane as the limiting guide roller 14, that is, the welding plate is in the same plane as the wheel hub after being clamped by a set of welding plate positioning clamps 6.
