Description
Technical field
The present invention relates to toolings, and in particular, to the processing tool and method of spring end face grinding.
Background technique
Valve is as the mechanical device for flowing or adjusting flow parameter in each model system of space flight for controlling fluid.It is led
Wanting function is to open and stop the flowing of fluid.Only there are two states for valve, open or close.Wherein, spring is in valve spool of valve
The important function that unlatching, reset, closing are played in the structures such as component is widely present in all kinds of valve mechanisms: such as: electromagnetism
Valve, latching valve, pressure reducing valve plus valve, safety valve etc..
Spring has one of pincers worker process after coiling, cutting, heat treatment, is mainly used for refining both ends of the surface, guarantees spring force
And verticality.Spring force is bigger than normal, valve opening time lag.Verticality is unsatisfactory for requiring, and there are spool jams, valve tightness
It can not the hidden danger up to standard that valve invalidations be waited.By taking safety valve as an example, once occur spring failure, local influence be not can guarantee and
When pressure release or guarantee in time close；It is the excessively high harm system safety of vent pressure on upper level influence, closes hypotony and cause
Pressurization gas excessive loss；Final harm system safety, gas excessive loss.Therefore, the processing in both ends of the spring face just seems outstanding
It is important.
Existing both ends of the spring face processing is it is difficult to ensure that the spring force of spring and the stability of verticality.Usually operator
The hand-held spring of member, is ground close to grinding wheel, and spring sizes that such processing method obtains, geometric tolerance be unstable, qualification rate
It is low.Meanwhile such processing method process-cycle length, low efficiency, personnel requirement are high.
Tooling of the invention can solve the above problem using easy to operate, and at present on the market without such processing side
Method.
