Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a raw material strip welding mechanism. Background Art

[0002] In the precision electronics manufacturing and stamping industry, the processing of strip raw materials is a crucial link. TIG welding technology is widely used in the processing and manufacturing of strip raw materials due to its many advantages such as high welding quality, beautiful welds, and small heat-affected zone. When TIG welding technology is applied to actual production, it needs to be implemented with the help of a special welding mechanism.

[0003] In the existing welding mechanism, the distance between the welding gun and the material strip carrying component needs to be adjusted according to the thickness of the material strip. The adjustment operation of the distance is specifically to adjust the height of the welding gun. The height of the welding gun is mostly adjusted by a threaded advancement mechanism. In order to ensure the stability of the welding gun after the height is adjusted, a tightening and positioning mechanism is often specially configured for the threaded advancement mechanism. However, the relative positions of the tightening and positioning mechanism and the threaded advancement mechanism are not set reasonably. The driving components of the two mechanisms are not located at the same water level and have a certain distance between them, which causes the hands to move additionally and significantly when operating the two mechanisms. The operation is relatively cumbersome and inconvenient, which indirectly reduces the efficiency of the above distance adjustment operation. Utility Model Content

[0004] In view of this, the present invention provides a raw material strip welding mechanism to solve the problem of low efficiency in adjusting the distance between a welding gun and a strip carrying component.
