Description

Technical Field

[0001] The utility model relates to the field of condensers, in particular to a condenser metal parts welding device. Background Art

[0002] A general condenser is mainly composed of a continuous S-shaped bend and a metal plate or wire mesh, which are fixed by spot welding. Heat exchange is completed by the medium transported by the S-shaped bend. The welding process is a routine and indispensable task in condenser manufacturing activities.

[0003] Because the S-shaped elbow structure of the condenser is relatively complex, long and has many bending points, more welding points need to be set between it and the metal plate and the wire mesh to improve the welding stability of the two. Due to the large number of welding points and the large distribution range of their positions, the welding work is relatively complicated, troublesome and time-consuming. In particular, during welding, the staff is required to constantly adjust the position of the condenser relative to the welding gun, which further reduces the welding efficiency.

[0004] Therefore, in order to address the problem that there are many and widely distributed welding points between the metal plates and the bent pipes of the above-mentioned condenser, and that the welding work is complicated and time-consuming due to constant adjustment of the condenser position during the welding process, a welding device can be designed that automatically adjusts and shifts according to the spacing between adjacent pipes of the S-shaped bent pipe of the condenser, thereby eliminating manual adjustment and improving the welding efficiency of the condenser.
