Description

Technical Field

[0001] The invention relates to the technical field of power divider production, and in particular to a power divider welding device. Background Art

[0002] A power divider is a device that divides one input signal energy into two or more outputs of equal or unequal energy. It can also combine the energy of multiple signals into one output. A power divider is also called an overcurrent divider. It is divided into active and passive types. It can evenly divide one signal into several outputs. A power divider is generally composed of an internal core rod and an aluminum alloy shell. In order to ensure the compactness of the shell at the branching head, it is usually sealed by welding after the shell is buckled on to enhance its anti-interference performance.

[0003] After searching, it is found that in the prior art, the welding of power dividers is mostly done by robot welding. However, since the weld of the power divider is relatively short, if the weld cannot be kept horizontal, it is very easy to cause the overall skewness of the weld during welding. Therefore, we propose a new welding device that can ensure that the welding position of the power divider, that is, the weld is always kept horizontal during loading, so as to ensure that the shell is complete and seamless after welding. Summary of the invention
