Description

Technical Field

[0001] The utility model relates to the field of jigs, in particular to an adsorption positioning jig for bipolar plate processing. Background Art

[0002] The application of bipolar plates performs very well in the production of hydrogen by electrolysis of water. An electrolytic cell is required in the process of producing hydrogen by electrolysis of water, and the bipolar plate happens to be one of the key components of the electrolytic cell. In the process of producing hydrogen by electrolysis of water, water will be heated to a certain temperature and then direct current electrolysis will be used to decompose water molecules to generate hydrogen and oxygen. In this process, the bipolar plate acts as the two plates in the electrolytic cell. Compared with traditional electrolytic cells, the advantage of bipolar plates is that their manufacturing materials are better, with higher electrical conductivity and stronger stability. In practical applications, fine processing of bipolar plates is required, and jigs and tooling are required. A fuel cell metal bipolar plate dispensing fixture disclosed in application number CN202121482080.0 is recorded, which includes a jig base, a pressure plate, and a cover plate. The jig base is provided with cover plate fixing holes, workbench fixing holes, and metal bipolar plate positioning holes. The front of the jig base is processed There are steps matching the metal bipolar plate and grooves matching the air ports of the metal bipolar plate. Several countersunk holes are distributed on the back of the fixture base to embed magnetic columns. The cover plate covers the air port position of the metal bipolar plate on the front of the fixture base and is locked into the cover plate fixing hole by bolts. The pressure plate covers the position without air ports in the middle of the metal bipolar plate. The fixture applies a certain pressure to the metal bipolar plate by the cover plate and the pressure plate through the action of bolt locking and the magnetic force of the magnetic column, so that the metal bipolar plate reaches a relatively ideal flat state. The above-mentioned bipolar plate processing fixture is based on the same principle as the positioning device for processing bipolar plates of alkaline water electrolysis hydrogen production electrolyzers, but the device has the following defects in actual use: the device is not convenient for fixing the bipolar plate during use, making the processing unstable, and lacks a positioning structure, which is not convenient for fine processing of the product. Therefore, it is necessary to design a practical adsorption positioning fixture for bipolar plate processing. Utility Model Content
