The purpose of this utility model is for the deficiencies in the prior art part, and a kind of prefill valve lapping device simple in structure is provided, and it greatly reduces labour intensity, has improved grinding efficiency, and grinding effect is better.
For achieving the above object, the utility model adopts following technical scheme:
The prefill valve lapping device comprises frame, and described frame is provided with valve body mounting base and Spool rotating driven unit; The below of the corresponding valve body mounting base of described frame is provided with a pneumatic type spool jacking assembly.
As preferably, described Spool rotating driven unit is comprised of reductor and spool coupling assembling.
Further,, described frame mainly is comprised of upper spider and bearing support, and described valve body mounting base is arranged on the described upper spider, and described pneumatic type spool jacking assembly is installed on the described bearing support.
As preferably, described pneumatic type spool jacking assembly comprises: a cylinder, its cylinder part vertically are arranged on the described bearing support; One pneumatic control component is connected with described cylinder by tracheae; With a hydraulic bjuffer, be arranged on the piston rod of cylinder distolateral on.
As preferably, described cylinder is the quick return cylinder.
As preferably, described pneumatic control component comprises: a source of the gas; One source of the gas is processed three linked piece, is connected with described source of the gas by tracheae; With a foot valve, be connected with rodless cavity with the rod chamber of source of the gas processing three linked piece and cylinder respectively by tracheae.
Further preferred, series connection access one rapid escape valve on the tracheae of described foot valve and cylinder rodless cavity.
As preferably, the central lines of the center line of described cylinder and described valve body mounting base.
The utility model adopts spin finishing and the lapping mode of automatically suppressing combination, makes the grinding between prefill valve spool and the valve body composition surface more even, and efficient is higher, and greatly reduces labour intensity, has saved the labour.

The specific embodiment
As depicted in figs. 1 and 2, prefill valve lapping device described in the utility model mainly is comprised of frame 1, Spool rotating driven unit and pneumatic type spool jacking assembly.
Frame 1 mainly is comprised of upper spider 11 and bearing support 12, and upper spider 11 is fixed on the bracing frame 12 by pressing plate 13 and some screws.Upper spider 11 is provided with the valve body mounting base 111 that filling liquid valve body 41 is fixed thereon.
Pneumatic type spool jacking assembly mainly is comprised of quick return cylinder 21, hydraulic bjuffer 22 and pneumatic control component.The cylinder part of quick return cylinder 21 vertically is arranged on the bearing support 12, the central lines of its center line and valve body mounting base 11.Hydraulic bjuffer 22 is installed in the piston rod end of quick return cylinder 21.Pneumatic control component is mainly processed three linked piece 231, foot valve 232, rapid escape valve 233 and some tracheaes 234 by source of the gas, source of the gas and formed: source of the gas is processed three linked piece 231 and is connected in series by tracheae 234 and source of the gas; Foot valve 232 is connected with rodless cavity with the rod chamber of source of the gas processing three linked piece 231 and cylinder respectively by tracheae 234; Rapid escape valve 234 series connection access foot valves are connected with the cylinder rodless cavity on the connection tracheae.
The Spool rotating driven unit mainly is comprised of reductor 31 and spool coupling assembling 32.Reductor 31 is installed on the upper spider 11 of valve body mounting base 111 tops.Spool coupling assembling 32 1 ends are connected with the output of reductor, and the other end is connected with prefill valve spool 42.
The course of work of the present utility model is as follows:
The prefill valve valve body is fixed on the valve body mounting base of upper spider, the prefill valve spool is put into the prefill valve valve body makes its lower end stretch out from prefill valve valve body below.The operation foot valve, make the rodless cavity air inlet of cylinder, the hydraulic bjuffer jacking prefill valve spool of cylinder piston boom end, and then operate rod chamber air inlet, the rodless cavity Quick air-discharge that foot valve makes cylinder, the prefill valve spool freely falls the bump valve body in the effect that loses top lift.Behind multiple impact, drive the prefill valve spool with respect to the rotation of prefill valve valve body by reductor, (need add abrasive pastes during grinding) ground on the composition surface between prefill valve spool and the prefill valve valve body mutually, thereby reaches desirable grinding effect.
