Assembly device with sealing effect

Abstract

The invention discloses an assembling device with a sealing function. The assembling device comprises a first separating body, a second separating body and a gasket, wherein the first separating body is provided with a first surface, the second separating body is provided with a second surface, the gasket is provided with a convex rib, the convex rib is in contact with the first surface and the second surface, at least one side of the convex rib is provided with a branch groove in a protruding way, at least one end of an elastic body which is fixedly arranged on the convex rib is embedded in the branch groove, and the elastic body is simultaneously in contact with the first separating body and the second separating body. Compared with the design of a traditional gasket, due to the additional arrangement of a glue groove and the elastic body, the sealing problem in a height difference can be completely solved, complete sealing can be achieved, and the sealing reliability can be increased; the gasket has a better adaptability on the height difference, the processing accuracy of a flange surface can be reduced, thus the processing efficiency is increased, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of mechanical processing and assembly, and in particular relates to a gasket, an assembly device containing the gasket and having a sealing effect, and a vacuum pump containing the assembly device. Background technique [0002] In modern machinery, for the feasibility of processing and assembly, a joint surface will be separated, and then assembled into a part, but in the whole assembly process, a certain height difference will be formed, due to the existence of the height difference, it will cause leakage Channel, not conducive to sealing. [0003] The traditional way to solve the sealing problem of this height difference is mainly to use a gasket seal 100' that is generally provided with ribs 101', such as figure 2 shown, and try to increase the bolt force to minimize the area of ​​leakage passage; figure 1 As shown, the height difference between the first split body 200' and the second split body 300' and the ga...

[0003] The traditional way to solve the sealing problem of this height difference is mainly to use a gasket seal 100' that is generally provided with ribs 101', such as figure 2 shown, and try to increase the bolt force to minimize the area of ​​leakage passage; figure 1 As shown, the height difference between the first split body 200' and the second split body 300' and the joint 400' of the gasket are in communication with the leakage channel, but no matter how much the axial force (in the direction P in the figure) is, there will be Leakage channels exist, resulting in slight leakage, and excessive axial force will affect the life of parts
