Summary of the invention
The purpose of this utility model provides a kind of Ni-MH battery vent valve pressure testing machine, mainly solves that manual inspection Ni-MH battery vent valve error is large, technical matters that cannot batch detection.
For achieving the above object, the technical solution of the utility model is: a kind of Ni-MH battery vent valve pressure testing machine, comprising: frame, and monitor station base plate is placed in frame, and two pressure testing bodies are placed side by side on monitor station base plate; One discharge is set on pressure testing body and puts the air release that detects workpiece, pressure testing body connects propelling movement cylinder; Pressure testing body top is provided with pressing plate, and pressing plate two ends are socketed on slide bar by linear bearing, and pressing plate upper surface is fixed with compression cylinder, is also provided with operation bench on base plate, and operation bench is provided with start button, digital display pressure switch and touch-screen.
The air release of pressure testing body is connected with quick connector, quick connector connects the fast threeway of inserting by tracheae, fast insert threeway and separately lead up to tracheae and connect digital display pressure switch, the fast Third Road of inserting threeway is by tracheae connected electromagnetic valve and pressurizer successively, installation and measuring workpiece in air release, detects workpiece and air release surface of contact and is sealed by sealing gasket.
Pressing plate is realized the compress and release action to vent valve to be detected; Push cylinder, pressure testing body is pushed, convenient artificial placement and taking-up vent valve, is placed on monitor station base plate; Start button, has two, realizes reset and unlatching to pick-up unit; Touch-screen realize control to whole vent valve monitoring device and detect the vent valve of surveying whether qualified; Digital display pressure switch, the pressure that vent valve in test process is born shows, shows whether be certified products simultaneously.
The utility model beneficial effect: on worktable, have the testing agency that two covers are identical, can place 8 vent valves for every group, realized the object of mass detection vent valve exhaust quality, improved detection efficiency; Detect vent valve by this Ni-MH battery vent valve pressure testing machine, can intuitively detect accurately the cracking pressure of vent valve and close valve pressure, simultaneously can manual adjustments vent valve test pressure and in vent valve test process, be provided with pressurizer and ensured the stability of test pressure, for the incoming test of vent valve provides effective detection means and equipment, ensure the quality of Ni-MH battery.
