Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile metal box processing, specifically relates to a lifting device for the air tightness detection of automobile metal box. BACKGROUND

[0002] The air tightness detection of automobile metal box is an important link to ensure that the metal container such as automobile fuel tank does not leak during use. The air tightness detection of automobile metal box aims to ensure that the metal box can withstand a certain pressure and maintain its sealing during use, thereby preventing fuel or other liquids from leaking and ensuring the safety and reliability of the automobile.

[0003] Since the weight and size of the automobile metal box are large, a lifting device is needed to facilitate the transportation of the automobile metal box to the inside of the detection equipment for detection.

[0004] The existing lifting device has the following problems during use:

[0005] The current lifting device generally uses clamping to position and support the automobile metal box when fixing it. However, this clamping method often has some drawbacks in actual operation. Specifically, since the clamping device directly contacts the surface of the metal box, and the clamping force needs to be large enough to ensure the stability of the metal box during lifting, it is easy to cause scratches on the surface of the automobile metal box. These scratches not only affect the appearance of the metal box, but also may adversely affect the corrosion resistance and sealing performance of the metal box.

[0006] More seriously, when the clamping force is too large, the automobile metal box may also deform. Deformation not only reduces the strength and durability of the metal box, but also may affect its compatibility and sealing with other parts of the automobile. Especially in some high-precision automobile manufacturing and maintenance processes, deformation of the metal box may cause the entire assembly process to fail, and even cause safety accidents.
