[0055] The support seat 16 is installed on the base 12 and directly below the pressing assembly 2 and is used to support the downward gasket mold 4.

[0056] The liquid receiving disc 17 is installed on the base 12 and directly below the cleaning and gluing assembly 3 and is used to collect the cleaning liquid falling in the cleaning process.

[0057] The diameter of the disc opening of the liquid receiving disc 17 is greater than the diameter of the inner hole of the bearing outer ring 5 to ensure that the falling cleaning liquid smoothly enters the liquid receiving disc 17.

[0058] The longitudinal guide rail sliding table 13 is composed of a guide light shaft 52, a light shaft support 53, a linear bearing 54 and a sliding plate 51; the guide light shaft 52 is provided with two, which are installed on the left and right sides of the middle of the base 12 through the front and rear light shaft supports 53; the left and right sides of the sliding plate 51 are respectively supported on the two guide light shafts 52 through the two linear bearings 54 and form a moving pair with them.

[0059] Referring to Figure 3 It can be seen that the pressing assembly 2 is composed of a first support 21, a pressing air cylinder 22, a gasket mold 4 and a mold connecting piece 25; the pressing assembly 2 is used to complete the pressing operation of the gasket.

[0060] The first support 21 is assembled by aluminum profiles and is supported on both sides of the front end of the base 12.

[0061] The pressing cylinder 22 is a three-axle cylinder, which is installed on the upper center of the first support 21 through the pressing cylinder connecting plate 24, and is used to provide the pressing movement required by the gasket mold 4.

[0062] The gasket mold 4 is installed on the piston end of the pressing cylinder 22 through the mold connecting piece 25. The gasket mold 4 is used for the fitting and pressing of the gasket and the taking out of the bearing outer ring 5.

[0070] The working principle and process of the gasket mold 4 are as follows:

[0071] ​When the lower end of the base 41 of the gasket mold 4 contacts the top end of the support seat 16, the silica gel bushing 42 is flush with the outer ring 5 of the bearing.
