Description

Technical Field

[0001] The utility model relates to a pole plate fixing device, in particular to a rotary pole plate fixing device used in pole plate welding. Background Art

[0002] The electrode plate is the core component of the electrolyzer, the core device for hydrogen production by water electrolysis, and is welded by the main electrode plate and the electrode frame. At present, there is a rotary welding device for circular electrode plates. However, due to the large inner diameter of the electrode frame and the easy deviation of the main electrode plate and the electrode frame during rotation, the welding quality is difficult to guarantee. Poor welding quality will cause deformation of the electrode plate, which not only affects the assembly accuracy and operating stability of the electrolyzer, but also makes it difficult to shape the electrode plate in the later stage. The existing technology uses a suspended tooling pressure plate to press the main electrode plate to reduce the deformation of the electrode plate welding, but this solution involves a hoisting device, which is too complicated.

By rotating the cross bar, the position of the pressing block can be adjusted to facilitate the loading and unloading of the plate; the support rod can be shortened by the cylinder, so that the pressing block can press the plate longitudinally, and the limit table can prevent the plate from lateral displacement during rotation, so that the plate can be effectively fixed during rotation welding. This plate fixing assembly has a simple structure and is easy to install and maintain.

[0010] Preferably, the tray includes a weld alignment assembly to make the edges of the main pole plate and the pole frame flush, thereby ensuring the welding effect.

[0011] Preferably, the alignment assembly is two raised concentric rings, and the weld is located between the two rings, so that the edges of the main pole plate and the pole frame are flush, ensuring the welding effect.

[0012] Preferably, the central rotating shaft of the tray is drivingly connected to the power output shaft of the driving motor, and the driving motor drives the pole plate to rotate through the shaft transmission.

[0013] Preferably, the drive motor is installed in the base to make the overall structure of the device more compact.
