[0002] The battery covers produced and prepared by the existing automated production lines need to be subjected to airtightness detection to ensure that the battery covers will not leak air, leak liquid, or intake air for oxidation and corrosion, so as to ensure the safety of the internal electrochemical performance of the battery and improve the safety and stability of the battery pack of new energy vehicles. In the related art, the rivet nuts holes on the battery cover are the detection difficulties, and it is difficult to accurately find the airtight problem of a certain rivet nut hole by using traditional detection means.

[0003] Therefore, in view of the deficiencies of the existing technology, it is necessary to design an airtight detection tooling for an automobile battery box to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above deficiencies in the existing technology, the purpose of the utility model is to provide an airtight detection tooling for an automobile battery box.

[0005] To achieve the above purpose and other related purposes, the technical solution provided by the utility model is: an airtight detection tooling for an automobile battery box, including a detection platform, on which a ring-shaped support seat matching and docking with the battery box is provided. An air injection hole is provided on the detection platform inside the inner circle of the ring-shaped support seat. On the detection platform outside the outer circle of the ring-shaped support seat, multiple sets of pressing mechanisms for pressing the battery box cover onto the ring-shaped support seat are provided. On the support surface of the ring-shaped support seat, airtight detection holes corresponding to the rivet nut holes of the battery box cover are provided. On the detection platform, water tanks corresponding to each of the airtight detection holes are also provided. The airtight detection holes and the water tanks are connected by air ducts.

[0006] The preferred technical solution is: the pressing mechanism is composed of a pressing cylinder and a pressing member. The pressing cylinder is fixedly arranged on the detection platform and located outside the outer circle of the ring-shaped support seat. The pressing member is driven by the pressing cylinder to move up and down and is used for pressing the battery box cover onto the ring-shaped support seat.

[0007] The preferred technical solution is: the pressing member is made of rubber material.

[0008] The preferred technical solution is: a limiting block for limiting the product is provided at the edge of the ring-shaped support seat.

[0009] The preferred technical solution is: a telescopic cylinder is provided on the detection platform outside the outer circle of the ring-shaped support seat. The telescopic cylinder is used to drive a sealing plug to block the wire outlet hole on the product.

[0010] The preferred technical solution is that the air injection hole is connected to an external airtight detection system through an air circuit, and a manual valve for controlling the opening and closing of the air circuit is provided on the detection platform.

[0011] Due to the application of the above technical solution, the beneficial effects of the present utility model are as follows:

[0012] An airtight detection tooling for an automotive battery box proposed by the present utility model sets airtight detection holes corresponding to the blind rivet nut holes of the battery box cover on the supporting surface of the annular support seat, and sets water tanks corresponding to each airtight detection hole one by one. The airtight detection holes are connected to the water tanks through air ducts, and water is injected into the water tanks. In this way, during the detection process, if a blind rivet nut hole leaks, bubbles will appear in the corresponding water tank. Through this tooling, the airtightness of the blind rivet nut holes of the battery box cover can be quickly detected, and it is suitable for popularization and use. Description of the Drawings
