Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary processing of vacuum tube tail feet frames, and particularly relates to a tail feet frame head spot welding device capable of double-head processing. Background Art

[0002] With the continuous improvement of people's living standards and the continuous enhancement of environmental protection and energy conservation awareness. At present, solar water heater projects are increasingly applied to public places such as hotels, restaurants, schools, residential buildings, office buildings, etc. In the heat collection module of the solar water heating system, the tail feet frame is the main device for installing vacuum heat collection tubes. Installation holes adapted to the vacuum tubes are opened on the end surface of the tail feet frame, and both ends have an open structure, and a head is required to seal them, which is convenient for protecting the vacuum heat collection tubes and also convenient for operation, and prevents other things from entering the tail support feet frame. The head is an irregular pentahedron that matches the end of the tail feet frame and has an opening at the top, and is generally spot welded to the tail feet frame.

[0003] At present, the commonly used spot welder has a single head. When performing spot welding, it is necessary to first complete the spot welding of one end and then take it out, and then insert the other end into the spot welding head for spot welding. When performing two-point welding, it is necessary to move the position of the workpiece to perform two-point welding, which takes a long production time and reduces the production efficiency.
