Description

Technical Field

[0001] The utility model relates to the technical field of tire frame clamps, in particular to an improved tire frame clamp. Background Art

[0002] During the production of large steel structures, such as large ship hatch covers, ship sections, and bridge segments, after the small components are fabricated, they must be assembled and welded on a jig during the intermediate assembly phase. Due to the numerous welds and significant shrinkage deformation during the assembly and welding process, these products must be secured to the jig to ensure accurate positioning. Once welding and assembly are complete, the jig is removed to produce the finished product.

[0003] During the construction process of fixing the workpiece to the tire frame, the traditional method is to weld the workpiece and the tire frame. This construction method is relatively cumbersome, and it is difficult to completely remove the tire frame and the weld bead between the tire frame and the workpiece after the product is assembled. At the same time, completely fixing the workpiece to the tire frame is not conducive to adjusting the vertical spacing between the workpiece and the tire frame, nor is it conducive to the free horizontal expansion and contraction of the workpiece during the production process, resulting in the workpiece still being greatly deformed after completion and a large amount of residual welding stress inside. In order to avoid this situation, the existing technology uses a tire frame clamp to fix the workpiece, which is convenient for adjusting the workpiece during processing. However, the existing tire frame clamp cannot be adjusted according to the width of the workpiece when connecting the workpiece to the tire frame, which affects the stability of the clamping. For this reason, we propose an improved tire frame clamp. Utility Model Content
