Welding frame

Abstract

The invention discloses a welding frame. The welding frame comprises a polar plate bearing structure, a first clamping unit, a second clamping unit and a first driving device; and a first limiting position capable of aligning multiple polar plates in the length direction of the polar plates and a second limiting position capable of aligning the multiple polar plates in the height direction of thepolar plates are arranged on the polar plate bearing structure. When the multiple polar plates are placed inside the polar plate bearing structure, the multiple polar plates can be stacked in an aligned manner, that is, tabs of the multiple polar plates are aligned to one another. Meanwhile, the first clamping unit and the second clamping unit are driven by the first driving device to attach the multiple polar plates tightly in the stacking direction of the polar plates, so that the relative movement caused by excessive looseness during welding and assembly of the multiple polar plates is avoided, the convenience is brought to the welding procedure of the tabs of the polar plates and bus plates, and the welding frame has the characteristic of good welding effect.

Description

technical field [0001] The invention relates to a welding frame. Background technique [0002] Electrode group welding is a manufacturing process that puts multiple plates of the same polarity in a row and inserts them into the welding tooth plates, and uses high-temperature flames to weld the tabs of the plates and the bus plate together. In this process, it is necessary Use a welding device to place and fix the plates. [0003] The existing welding device has deficiencies: in the actual production process, when multiple plates are arranged on the welding device, there is a phenomenon that multiple tabs are uneven. During welding, it is difficult for the manifold to connect with all The tabs of the polar plate are all aligned, which brings inconvenience to the welding of the tabs of the pole plate and the manifold, and has the disadvantage of poor welding effect. Contents of the invention [0004] When using the existing welding device to weld the manifold and tabs, it ...

AI Technical Summary

Problems solved by technology

[0004] When using the existing welding device to weld the manifold and tabs, it is difficult to stack multiple tabs neatly together, and it is difficult for the manifold to align with all the tabs, resulting in poor quality of welded products. Production is inconvenient; therefore, the existing welding device has the disadvantage of poor welding effect
