Detailed Description

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

As shown in fig. 1 to 8, the shaft dismounting device comprises a connecting shaft 1, a connecting plate 2, a clamping plate 3, a pressing plate 4, a sleeve 5 and an end plate 6, wherein the sleeve 5 is movably sleeved on the connecting shaft 1, the connecting plate 2 is fixedly arranged at one end of the connecting shaft 1, the end plate 6 is fixedly arranged at the other end of the connecting shaft 1, the clamping plate 3 and the pressing plate 4 are arranged on the connecting plate 2, notches are formed in the clamping plate 3 and the pressing plate 4, clamping blocks 301 are arranged in the notches of the clamping plate 3 as shown in fig. 4, the notches of the clamping plate 3 and the notches of the pressing plate 4 are sleeved on the shaft end of a shaft to be dismounted during dismounting, the clamping blocks 301 on the clamping plate 3 are clamped in clamping grooves in the shaft end of the shaft to be dismounted, so that the shaft to be dismounted is fixedly connected, then the sleeve 5 moves along the connecting shaft 1 and impacts the end plate 6 at the other side, and therefore the shaft is dismounted from a blind hole bearing.

As shown in fig. 2, both ends of the connecting shaft 1 are provided with threaded columns, as shown in fig. 3 and 7, the middle parts of the connecting plate 2 and the end plate 6 are provided with central threaded holes 201 matched with the threaded columns, and as shown in fig. 8, both ends of the connecting shaft 1 are provided with nuts 7 for axially locking the connecting plate 2 and the end plate 6.

As shown in fig. 1 and fig. 3 to 5, the connecting plate 2 is fixedly connected with the clamping plate 3 and the pressing plate 4 through screws, a plurality of screw holes 202 are uniformly distributed on the edge of the connecting plate 2 along the circumferential direction, a plurality of clamping plate connecting holes 302 are uniformly distributed on the arc-shaped edge of the outer side of the clamping plate 3, pressing plate connecting holes 401 are uniformly distributed on the arc-shaped edge of the outer side of the pressing plate 4, and the clamping plate connecting holes 302 and the pressing plate connecting holes 401 correspond to the screw holes 202 on the connecting plate 2 one to one for the screws to pass through.
