DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-Figure 3The figure shows a clamping device for welding a car steering wheel, comprising a fixed bracket 1, the fixed bracket 1 is rotatably connected to a positioning rod 2, the positioning rod 2 is rotatably connected to a locking block 3, one end of the positioning rod 2 is fixedly connected to a positioning tool 4, the other end of the positioning rod 2 is provided with a fixedly connected locking block 2 5, the positioning tool 4 comprises a base 401, a connecting rod clamp 402 is provided on the outside of the base 401, an outer ring clamp 403 is provided on the outside of the connecting rod clamp 402, and a central axis clamp 404 is provided at the central axis of the base 401. The utility model rotatably connects the positioning rod through the fixed bracket, one end of the positioning rod is connected to the positioning tool, the positioning tool comprises a base, a connecting rod clamp, an outer ring clamp and a central axis clamp, and a locking block and a locking block 2 are provided on the other end of the positioning rod, so that the staff can easily flip the steering wheel to weld the other side without re-fixing the clamp each time, which simplifies the operation steps and significantly improves the welding work efficiency.

[0020] Furthermore, a limit groove is provided inside the fixed bracket 1, and the limit groove is semi-annular in shape. The rotation angle of the limit groove is 180 degrees. Through the limit groove set inside the fixed bracket, the rotation angle of the limit groove is precisely set to 180 degrees, so that the steering wheel can be flipped 180 degrees directly on the bracket without additional adjustment or movement, which simplifies the steps of the flipping operation and improves work efficiency.

[0021] Furthermore, the limiting groove is slidingly connected to the positioning rod 2, and the positioning rod 2 includes a connecting rod 201, one end of the connecting rod 201 is fixedly connected to the limiting shaft 202, and the other end of the connecting rod 201 is fixedly connected to the connecting plate 203, and the connecting plate 203 is fixedly connected to the base 401. The positioning rod is slidably connected through the limiting groove, which provides great convenience for the fixing and flipping operations of the steering wheel, allowing the positioning rod to slide freely inside the limiting groove, thereby realizing flexible flipping and precise positioning of the steering wheel, simplifying the steps of the flipping operation, and greatly improving work efficiency.

[0022] Furthermore, a positioning block 204 is provided on one side of the limit shaft 202, and the positioning block 204 is slidably connected in the limit groove. The positioning block is provided on one side of the limit shaft and is slidably connected to enable it to run in the limit groove, thereby providing more precise positioning accuracy and consistency for the fixation of the steering wheel.

[0023] Furthermore, the locking block 3 is tightly pressed on the other side of the limit shaft 202. The locking block 3 is composed of a plug-in block 301 and a connecting block 302. The plug-in block 301 and the connecting block 302 are fixedly connected to one side of the fixed bracket 1. Through the design of the tightly pressed locking block on the other side of the limit shaft, when the limit shaft is tightly pressed on the locking block, the friction force generated between them can effectively prevent the steering wheel from moving or rotating unnecessary during the welding process, thereby ensuring the accuracy and quality of the welding.

[0024] Furthermore, a center rod 205 is provided at the center axis of the limiting shaft 202, and the center rod 205 is plugged into the interior of the fixed bracket 1. The center rod is specially designed at the center axis of the limiting shaft and is plugged into the interior of the fixed bracket, thereby providing a solid support point for the entire device, ensuring that the steering wheel will not shake or shift during the welding process, improving the accuracy of welding, and ensuring the stability and reliability of welding quality.

[0025] In this solution, the workflow is: first, make sure all parts are in their initial positions, especially the position of the positioning rod, and then place the steering wheel on the positioning fixture. The connecting rod of the steering wheel should be firmly clamped by the connecting rod clamp, and the outer ring should be fixed by the outer ring clamp.

[0026] At the same time, the center axis of the steering wheel should be tightly clamped by the center axis clamp to ensure the stability of the steering wheel during the welding process. After the steering wheel is firmly clamped, the welder can start the welding operation. After the top surface welding is completed, turn the positioning rod to make it slide along the limit groove inside the fixed bracket until the steering wheel reaches the appropriate welding position. During this process, the positioning block will slide in the limit groove to ensure the accuracy of positioning.

[0027] When welding is complete, turn the positioning rod again and remove the steering wheel from the positioning fixture.
