Pull-type automobile battery shell sealing performance detection equipment capable of reducing frictional loss

Abstract

The invention discloses pull-type automobile battery shell sealing performance detection equipment capable of reducing frictional loss. The equipment comprises a water tank, guide mechanisms, an air suction pipe and an inserting block, wherein the water tank is arranged at the inner side of a device body, the inner side of the device body is provided with a supporting platform, and the upper end of the device body is provided with a clamping plate for fixing a battery shell; the guide mechanisms are installed on the left side and the right side of the supporting platform, a guide rod is installed on the side of the supporting platform in a penetrating mode, a pull rope is arranged on the side of the guide rod, and the end of the pull rope is fixedly connected to the upper end of a vertical rack; the air suction pipe is mounted on the side of the connecting column, and the side of the connecting column is connected with a flow guide pipe; and the inserting block is communicated with the flow guide pipe. According to the pull-type automobile battery shell sealing performance detection equipment capable of reducing the frictional loss, limiting and fixing of the battery shell can be achieved through power of the equipment, meanwhile, the interior of the battery shell can be automatically inflated, and it is prevented that additional electrical elements are needed for assistance.

Description

technical field [0001] The invention relates to the technical field related to automobile batteries, in particular to a traction-type automobile battery casing airtightness detection device capable of reducing friction loss. Background technique [0002] The car battery is the power source of the new energy vehicle. When the car battery is used in the new energy vehicle, it is usually placed in the corresponding battery case to work, and the car battery is well protected by the battery case. Therefore, the sealing detection device is usually used in the process of battery case production, so as to prevent the occurrence of fine seams during welding of the battery case, which will affect the subsequent normal use. [0003] However, the existing leak detection devices have the following problems: [0004] For example, the publication number is CN109387340A, a device and method for detecting air tightness of a new energy vehicle power battery pack casing, which includes two fi...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a traction-type automobile battery case airtightness detection device that can reduce friction loss, to solve the problem that the existing airtightness detection device on the market proposed by the above-mentioned background technology needs to check the battery during use. Auxiliary electrical components are needed to limit the position of the battery pack box and inflate the inner cavity of the battery pack box. Automatic inflation, when using too many electrical components not only increases the overall cost of use, but also greatly increases the difficulty of later maintenance, thus greatly reducing the practicality of the leak detection device
