Problems solved by technology

[0003] The existing welding jig for capacitor shell processing has the following technical defects in use: during the clamping process of the capacitor shell, due to the different shapes of the capacitor shell, it is difficult to achieve stable clamping, resulting in easy shaking during the welding process, thus It affects the welding effect. At the same time, the capacitor shell has various shapes. When clamping an irregular shell, the clamping force of the capacitor shell is constant everywhere, resulting in different clamping forces for the shell, which makes the shell The body is prone to pressure deformation and needs to be improved

Description

technical field [0001] The invention relates to the technical field of capacitor processing, in particular to a welding fixture for processing capacitor casings. Background technique [0002] In the process of integrated packaging of capacitor products, the corresponding electrical components need to be welded on the surface of the capacitor shell, so that the capacitor can meet the needs of production and use. In the welding process, in order to ensure the accuracy of welding, the surface of the capacitor needs to be stably clamped to avoid welding. The shaking of the capacitor shell during the process improves the welding quality of the capacitor product. [0003] The existing welding jig for processing capacitor shells has the following technical defects in use: during the clamping process of the clamp to the capacitor shell, due to the different shapes of the capacitor shell, it is difficult to achieve stable clamping, resulting in easy shaking during the welding process...
