The content of the invention
The utility model is aiming above mentioned problem, there is provided a kind of high fluid pressure type of automaticity, which moves back, unloads bushing compression dress
Put.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts the following technical scheme that, the utility model bag
Include pressing plate, pressure ring and plug ring, it is characterised in that：The trip bolt that can coordinate with crankshaft end-face screw is provided with the pressing plate；
Annular groove is provided with the side end face of pressure ring one；The plug ring surface is provided with the convex hole coordinated with annular groove, plug ring end
Face is provided with positioning spigot；Pressure ring outer surface is provided with the oil filler point in gap between connection annular groove and convex hole；The pressure ring
It is arranged between pressing plate and plug ring.
As a kind of preferred scheme of the present utility model, the positioning spigot of plug ring is provided with sleeve pipe.
As another preferred scheme of the present utility model, the pressure ring surface is provided with locating slot corresponding to pressing plate.
The beneficial effects of the utility model：The utility model not only increases the automation of membrane-pump power-end assembling process
Degree and bearing assembly precision, membrane-pump power-end key component also greatly improved disassembles installation, the work of repair and maintenance effect
Rate.In addition, the utility model also has many advantages, such as structure is novel, workable, easy to process concurrently.
