Embodiment Construction

[0046] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0047] Thin steel strip butt tungsten argon arc welding fixture, including work table, cylinder connector, fixture fixing plate and master form, specifically as follows:

[0048] 1. Countertops and profiles

[0049] The center of the worktable is provided with a forming groove, and the left and right sides of the forming groove are symmetrically provided with guide holes; one side of the forming groove is provided with a pattern positioning hole, and the distance between the center of the pattern positioning hole and the middle of the forming groove is It is equal to the distance from the center of the boss below the cam to one edge of the cam, so that when the cam is fixed in the positioning hole, the other edge of the cam is just in the center of the forming groove.

[0050] Such as image 3 As shown, there are two cylindrical bosses at the bo...

Abstract

The invention discloses an argon tungsten-arc welding clamp for butt joint of thin steel strips and a using method. A clamp pressing block is based on a piano keyboard clamp and still adopts a piano keyboard pressure block by utilizing the characteristics of even clamping force and high reliability of the piano keyboard clamp, and meanwhile, a movement mechanism of the clamp is designed. Therefore, the clamp can move in a clamping process of a test specimen, so that the steel strips can be conveniently fed, clamped and taken out after being weld, so as to finish taking out of the test specimen. The defect that the traditional piano keyboard clamp cannot be used for welding long steel strips and has complicated clamping procedure is overcome, and meanwhile, the disadvantages of uneven stress of the test specimen caused in a pressing process of a lifting clamp are also overcome, and the argon tungsten-arc welding clamp has high use value.

Description

technical field [0001] The invention belongs to the technical field of material processing, and more specifically relates to a thin steel strip butt tungsten argon arc welding fixture and a use method. Background technique [0002] With the continuous development of welding technology, various welding techniques are widely used in aerospace, shipbuilding, automobiles, bridges, construction and other fields. The welding fixture is the process equipment that accurately positions and reliably clamps the welding test piece, facilitates the assembly and welding of the test piece, and ensures the accuracy of the welding structure. With the continuous development of welding technology, how to ensure the quality of welded structures depends to a certain extent on welding fixtures. For different welding methods and welding structures, various new and special welding fixtures have been designed and developed to solve specific welding problems. [0003] With the development of modern...
