Description

Air tightness detection fixture tool Technical Field The utility model relates to the field of fixture tools, in particular to an air tightness detection fixture tool. Background The air pressure method is a commonly used air tightness detection method, and is mainly used for judging whether leakage exists or not by monitoring the change of the sealed container under the air pressure. The principle and the operation mode are simpler, and the method is suitable for various different application scenes The air tightness detection of the battery box is used for ensuring that the battery box can keep tightness in the use process, and preventing external substances (such as moisture, dust, gas and the like) from entering or internal gas from leaking, so that the safety, stability and long service life of the battery box are improved. Air tightness tests are commonly used for quality control of battery box design and manufacture, especially in some applications requiring high requirements for water resistance, dust resistance, explosion resistance, etc., such as electric vehicles, electric tools, energy storage systems, etc. Before detection, the battery box needs to be fixed, the traditional manual opening and closing clamp requires that the arm strength and the endurance of staff are good, so that the staff can work adequately, the general male staff can hardly guarantee long-time operation, and the problem of low fixing precision exists. And there is certain hole on the battery box, need carry out the shutoff when detecting, but the battery box of different models, hole position have certain difference, if the shutoff is improper, there is the risk of gas leakage, and then influences the detection accuracy. Disclosure of utility model The utility model aims to provide an air tightness detection fixture tool which is used for solving the technical problems in the background technology. The technical scheme of the utility model provides an air tightness detection fixture tool which comprises a base, a support frame arranged on the base, a pressing component and a plugging component, wherein the pressing component and the plugging component are positioned on the periphery of the support frame; A sealing structure is arranged in the supporting frame, the battery box is inverted in the supporting frame and is supported by the sealing structure, and a sealing detection cavity is formed between the battery box and the supporting frame; The pressing component comprises a rotary driving piece, a pressing driving piece connected with the rotary driving piece and a pressing block connected with the pressing driving piece; the plugging assembly comprises a telescopic piece and a plugging block in telescopic connection. In a preferred embodiment, the pressing-down driving member includes a pressing-down cylinder, and a mounting plate is provided at a bottom of the pressing-down cylinder, and is connected to the rotation driving member. In a preferred embodiment, the lower pressing block is provided in a U shape, and the lower pressing block is connected with the output end of the lower pressing cylinder. In a preferred embodiment, the rotary driving member comprises a driving motor, a driving wheel, a belt and a tensioning wheel set, and the bottom of each mounting plate is connected with one driving wheel. In a preferred embodiment, the telescopic member comprises a telescopic cylinder, the output end of the telescopic cylinder is connected with a mounting seat, and the plugging block is movably arranged on the mounting seat.
