Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a rotating clamp for welding. Background Art

[0002] Welding is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. A fixture refers to a device used to fix the object being processed during the mechanical manufacturing process so that it occupies the correct position for construction or testing. It is suitable for any process in the process. A fixture is required when welding the workpiece.

[0003] The patent with the patent authorization announcement number CN220073756U discloses a welding fixture, including an operating table, a slide rail is provided on the operating table, bearings are installed on both side walls of the slide rail, a bidirectional threaded rod is sleeved in the bearing, one end of the bidirectional threaded rod is sleeved in the bearing of one side wall of the slide rail, and the other end of the bidirectional threaded rod passes through the bearing on the other side of the slide rail and is placed outside the bearing. Although the above patent can drive the fixtures to approach or move away from each other through the rotation of the bidirectional threaded rod, so that the fixture is convenient for clamping the welded parts, there are still some shortcomings in actual use. For example, when the fixtures approach each other to clamp the welded parts, the welded parts are fixed on the operating table, so the angle of the welded parts presented in front of the staff is fixed, resulting in that when welding different positions of the welded parts, the welding operation must be suspended halfway, and then the angle of the welded parts must be adjusted and clamped again before welding can be continued. The above situation complicates the welding operation of the welded parts and seriously reduces the welding efficiency of the welded parts. In order to solve the above problems, a rotating fixture for welding is proposed. Summary of the invention

[0004] The utility model aims to solve the above problems and provides a rotating clamp for welding.
