Abstract

The invention provides a power battery frame air tightness detection pressing mechanism, and relates to the technical field of air tightness detection. The power battery frame air tightness detection pressing mechanism comprises a fixed installation frame, a fixed top frame cross rod is welded and fixed between the two sides of the fixed installation frame, two air cylinder fixing bases are welded and fixed to the two ends of the lower surface of the fixed installation frame correspondingly, and two high-precision rack synchronous lifting assemblies associated with each other are fixedly mounted on each high-precision rack synchronous lifting assembly fixing plate. A fixed knob in a battery frame fixing assembly is rotationally meshed with a middle movable screw rod, and a movable fixing block at the front end is pushed to enable a battery frame to be tightly abutted between the battery frame fixing assembly and an abutting plate. As different battery frames are different in appearance, movable balls added in the design are arranged in movable ball grooves and are linked with two fixing columns at the front end to abut against the battery frame, so that the position of the battery frame can be kept unchanged before detection, and the air tightness detection effect is ensured.

Description

technical field [0001] The invention relates to the technical field of air tightness detection, in particular to a compression mechanism for air tightness detection of a power battery frame. Background technique [0002] At present, the power battery is the power source that provides the power source for the tool, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. It is mainly different from the starter battery used to start the car engine. Valve-port sealed lead-acid batteries, open tubular lead-acid batteries and lithium iron phosphate batteries are mostly used. Among them, the airtightness of the power battery shell needs to be tested before assembly to prevent the electrolyte in the power battery from leaking and causing accidental damage. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a p...
