Description

Technical Field

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

[0002] Welding is the most commonly used processing method to connect two or more metal parts into one component. The resulting component usually has high strength in all directions. Welding can be used not only to connect all the same metals and alloys, but also to connect metals with different strengths or dissimilar metals.

[0003] Electric welding fixtures are used to ensure the size of welded parts, improve assembly accuracy and efficiency, and prevent welding deformation. Due to the complex shapes of some parts used, the mold structure used for one-time molding is too complex, the production is difficult and the cost is high. Therefore, in the existing production, some parts with complex shapes are usually divided into multiple small parts, and these small parts are assembled and welded together to achieve the rapid formation of complex parts.

[0004] Therefore, it is necessary to use a stable fixture for electric welding to fix the two parts to be welded through a clamping plate, and to contact each other for welding.

[0006] The device is provided with a slide groove, a pulley and a fixing rod. The two objects to be welded are placed in front of the baffle. The rotating rod is twisted, and the rotating rod drives the threaded shaft to rotate. The threaded shaft pushes the clamping plate. At this time, the pulley under the clamping plate moves in the slide groove to fix the object between the clamping plate and the baffle. This makes it convenient to quickly move the clamping plate to fix the welding object.

[0032] Moreover, a second connecting hole 14 is formed at the top of the adjusting slot 4, and the second connecting hole 14 and the first connecting hole 22 are aligned vertically. A rotating rod 2 passes through the inside of the first connecting hole 22 and the second connecting hole 14. The rotating rod 2 is a threaded rod structure and is vertically arranged and slides through the second connecting hole 14 and is threadedly connected to the first connecting hole 22. The rotating rod 2 is rotatably installed and connected to the adjusting plate 6. Therefore, forward or reverse rotation of the rotating rod 2 can drive the slider 21 to move up and down along the adjusting slot 4.

[0033] Furthermore, a placement plate 3 is fixed to the outer side of the slider 21. The placement plate 3 is a rectangular plate structure and is horizontally arranged on the inner side of the adjustment plate 6 and is in sliding contact with the inner side of the adjustment plate 6.
