Pressing device for locating element axle b alignment pin and for the shaft parts b that is fixed and clamped, the limited block are used to be enclosed on
On the shaft parts b for being positioned and being fixed and clamped.
The base is provided with guide rail, and positioning support is slidably connected by guide rail and base.
On base or on guide rail one at be provided with for stationary positioned bearing operating position block.
A kind of pressing method being interference fitted for bushing with axle, employs described press-loading apparatus, comprises the following steps：
（a）Before press fitting, first bushing a is clamped by clip, is then heated at high temperature；
（b）During press fitting, first shaft parts b is placed in press-loading apparatus, by positioning support and positioning finger setting, by pressing device
It is fixed；Then clip is installed on shaft parts b together with bushing a, while grip jacket casing is on clip；And then limited block is pacified
It is attached on shaft parts b, the lower surface of limited block is bonded with shaft parts b shoulder；Finally start the pump housing, hydraulic cylinder is produced company
Continue stable pressure, clip is pressed, when the lower surface of clip is bonded with the upper surface of limited block, bushing a is installed in place；
（c）After press fitting, load is laid down, so as to complete the press fitting of bushing a and shaft parts b interference fits.
Advantages of the present invention：Product after being processed using the present invention, through examining, high yield rate, the mechanical property of product（By force
Degree, wearability）First mate's lifting is obtained, substantially meets the needs in production.
