Problems solved by technology
Since the working principle of the sleeve-type explosion-proof pressure tester is to directly press the indenter on the bottom of the aluminum shell, the contact area is large, so after the oil pressure rises and explodes, a large crack will generally be formed, and only the basic Explosion-proof pressure, but the effect of point explosion (the cracking degree of the bottom of the aluminum shell after the pressure is released) cannot be measured

The invention discloses a clamp device for testing point explosion aluminum shell anti-explosion pressure.The device comprises an aluminum shell fixing block (3), a base positioning plate (4), a base (1), a supporting rod (5), a positioning plate (8), a connecting rod (9) and an adjusting hand wheel (10).The middle of the positioning plate (8) is movably provided with the connecting rod (9) through threads.The upper end of the connecting rod (9) is fixedly connected with the adjusting hand wheel (10).The lower end of the connecting rod (9) is connected with a pressing head (6).The bottom of the base positioning plate (4) is provided with a T-shaped groove for fixing the aluminum shell fixing block (3), an oil inlet (11) is formed inside the base (1), and a through hole is reserved in the base positioning plate (4) relative to the base (1).The clamp device is simple in structure and convenient to operate and can accurately test the point explosion aluminum shell anti-explosion pressure and the cracking degree of the bottom of an aluminum shell after the pressure is released.According to the testing result, whether the point explosion aluminum shell is qualified or not is judged, and testing data is accurately displayed.
Description
technical field [0001] The invention relates to a fixture device on an explosion-proof pressure tester, in particular to a fixture device used for testing the explosion-proof pressure of an aluminum shell at point explosion and the cracking degree of the bottom of the aluminum shell after the pressure is released. Background technique [0002] At present, capacitor manufacturers have higher and higher requirements for aluminum shells. Compared with ordinary explosion-proof aluminum shells, some high-end explosion-proof aluminum shells must also have point explosion requirements. However, the currently used aluminum shell explosion-proof pressure tester adopts a sleeve type when measuring. Since the working principle of the sleeve-type explosion-proof pressure tester is to directly press the indenter on the bottom of the aluminum shell, the contact area is large, so after the oil pressure rises and explodes, a large crack will generally be formed, and only the basic Explosio...
