Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the inflatable rubber sleeve pressing-in device comprises a shaft 1, a rubber sleeve base 4 and a supporting seat 3, wherein the rubber sleeve base 4 is positioned between the shaft 1 and the supporting seat 3, the rubber sleeve 2 is placed on the rubber sleeve base 4, the rubber sleeve base 4 enables the rubber sleeve 2 to be roughly positioned, and a groove matched with the shape of the bottom surface of the rubber sleeve 2 can be formed in the rubber sleeve base 4 for ensuring the stability of the rubber sleeve 2 on the rubber sleeve base 4.

The below of axle 1 is equipped with axle stopper 7, is equipped with supporting seat stopper 6 between supporting seat 3 and the gum cover base 4, and restriction axle 1 and 3 relative positions of supporting seat let the accurate assembly of gum cover 2 in preset position. The moving part is limited according to whether the shaft clamping jig 5 drives the shaft 1 to move or the supporting seat 3 to move in the specific implementation, and therefore the relative moving distance can be accurately limited.
