Abstract

The invention relates to detection equipment of automobile parts, in particular to a sealing structure of an automatic transmission clutch shell sealing tester. The sealing structure comprises an upper sealing fixture, a lower sealing fixture and a sealing fixture base, wherein the lower sealing fixture is arranged on a workbench of the tester; the sealing fixture base is arranged on the lower sealing fixture and linked with the lower sealing fixture; and the upper sealing fixture can be arranged above the sealing fixture base in a way of vertical reciprocating motion. In the invention, on the basis of the elastic deformation principle of the sealing ring, the deformation and resetting, which occur before and after a workpiece to be tested is mounted in the test fixtures, of the searing ring are controlled by using a mechanism structure and the drive of an air cylinder, so a searing piece is not damaged and a sealing effect is realized. Thus, the service life of the sealing ring is prolonged and the use cost is reduced.

Description

technical field

[0001] The invention relates to testing equipment for auto parts, in particular to a sealing structure of an automatic transmission clutch housing sealing testing machine. Background technique

[0002] The inner and outer surfaces of the automobile automatic transmission clutch housing are cylindrical surfaces. In the process of sealing the automobile automatic transmission clutch housing, it is required to seal the inner and outer surfaces of the workpiece. In the existing cylindrical inner and outer surface sealing and sealing structures, most of them use special seals for sealing. The disadvantage is that the structure is complex, and the seals must be molded. Since the seals are consumable parts during use, it will inevitably cause The cost is high, the use is inconvenient, and it is not suitable for the working condition of the workpiece with multiple seals on the outer surface of the same cylinder. Contents of the invention

[0003] In order to solve...
