Gun type electric resistance welding transposition device

Abstract

The invention relates to a gun type electric resistance welding transposition device. The gun type electric resistance welding transposition device comprises a gun type electric resistance welding gun, transposition positioning pins, a welding gun positioning seat, a positioning key, a transposition outer ring, a locking nut and a transposition inner ring, wherein the gun type electric resistance welding gun is fixed on the welding gun positioning seat, the welding gun positioning seat is installed in the transposition inner ring through the positioning key, the transposition inner ring is sleeved in the transposition outer ring, the transposition inner ring and the transposition outer ring are clamped by the locking nut, the transposition outer ring is fixed on a transposition outer ring fixing seat, the positioning pins are installed in the transposition outer ring, a plurality of positioning pin holes are formed in the transposition inner ring, and a certain positioning pin hole can be connected with the transposition positioning pins only by loosening the locking nut and rotating the transposition inner ring. Due to the fact that pin holes of different angles are formed in the transposition inner ring, the gun type electric resistance welding transposition device can achieve multiple-angle transposition of the gun type device welding gun. The gun type electric resistance welding and transposition device has the advantages of being simple in structure, convenient to use, rapid in transposition and alignment, capable of being used on solar battery welding automatic production, and excellent in effect.

Description

technical field [0001] The invention relates to an indexing device, in particular to a gun-type resistance welding indexing device with simple structure, convenient use, fast indexing and centering. Background technique [0002] During the production of solar cell arrays, it is necessary to weld the positive and negative output terminals of several solar cell modules and the lead wires through resistance welding. figure 2 For the vertical direction, due to the different positions of the solar cell modules, the gun-type resistance welding torch head needs to be welded in the horizontal direction in addition to welding in the vertical direction, such as image 3 As shown, at present, the vertical direction welding and horizontal direction welding of the gun type resistance welding torch are realized by replacing the mounting surface of the gun type resistance welding torch, so that in production, only after all vertical direction welding is completed, the gun type resistance w...

[0002] During the production of solar cell arrays, it is necessary to weld the positive and negative output terminals of several solar cell modules and the lead wires through resistance welding. figure 2 For the vertical direction, due to the different positions of the solar cell modules, the gun-type resistance welding torch head needs to be welded in the horizontal direction in addition to welding in the vertical direction, such as image 3 As shown, at present, the vertical direction welding and the horizontal direction welding of the gun type resistance welding torch are realized by replacing the mounting surface of the gun type resistance welding torch, so that in production, only after all vertical direction welding is completed, the gun type resistance welding torch is reinstalled. For welding in the horizontal direction, the production efficiency is low and the centering is difficult. A convenient, fast and automatic centering gun-type resistance welding indexing device is needed in production.
