It is fixed for carrying the positioning sleeve of power transmission shaft at the top of slide unit, slide unit；Guide pillar is installed between the bottom plate and upper plate, in the bottom plate
Between the pressing plate, the guide pillar is provided with the first compression spring, between the pressing plate and the upper plate, led around described
Post is provided with the second compression spring；Lifting arm is set between the pressing plate and the upper plate, the upper plate is fixed in its upper end
On, its lower end activity is fixed on the pressing plate；The affixed gold-plating in the middle of the affixed connection handle of upper plate crown center, its bottom
Knife.
Further, the guide pillar bottom is fixed on the bottom plate, and its top movable is fixed on the upper plate.
Further, extended at the top of the guide pillar above the upper plate.
Further, it is fixed on the upper plate, is set between the nut and upper plate by nut at the top of the lifting arm
Flexible pad.
Further, the lifting arm bottom is extended to below the pressing plate.
Further, the connection handle is fixed at the top of the upper plate by socket cap screw.
Compared with prior art, the application can be obtained including following technique effect：Front propeller shaft of the present invention in press-in
Have one by gold-plating knife automatic center locating process, in gold-plating knife in endoporus correcting process, pressing plate keeps good to power transmission shaft all the time
Positioning states until gold-plating knife exits working condition, meet separating pressure machine pressure during bushing press-mounting and promote boom end
Running precision, it is ensured that required precision of the press-in piece relative to work top.

Embodiment
Presently filed embodiment is described in detail below in conjunction with drawings and Examples,
As shown in figure 1, a kind of bushing of transmission shaft press-fit with correction device, including set gradually from bottom to top bottom plate 4,
Pressing plate 7, upper plate 11, it is characterised in that：Slide unit 1 is provided with described 4 times setting cushion blocks 2 of bottom plate, the cushion block 2, the top of slide unit 1 is solid
The fixed positioning sleeve 3 for being used to carry power transmission shaft；Guide pillar 5 is installed, in the bottom plate 4 and the pressure between the bottom plate 4 and upper plate 11
Between plate 7, the guide pillar 5 is provided with the first spring, between the pressing plate 7 and the upper plate 11, set around the guide pillar 5
There is second spring；Lifting arm 9 is set between the pressing plate 7 and the upper plate 11, and its upper end is fixed on the upper plate 11, its
Lower end activity is fixed on the pressing plate 7；The affixed gold-plating knife in the middle of the affixed connection handle 12 of the crown center of upper plate 11, its bottom
10。
Further, the bottom of guide pillar 5 is fixed on the bottom plate 4, and its top movable is fixed on the upper plate 11,
Upper plate 11, bottom plate 4 are the next along in the guide pillar 5 generation in the presence of forcing press, the first compression spring 6, the second compression spring 8
