Description

A kind of valve straightener

Technical field

The utility model is related to a kind of for correcting the mechanical equipment of the morpheme meter of machined part；It is specifically a kind of Valve straightener.

Background technology

Valve is generally all using within the engine, needing the high-frequency reciprocating in the environment of high temperature and pressure to operate, to size The requirement of tolerance, geometric tolerance and mechanical strength is all higher；Valve includes bar portion and pan portion, is all to be heat-treated after processing, It is yielding after heated.

In order to correct, the scheme initially found out is similar to thread rolling machine, and two rotation axis vertical rotatings clamp and correct valve Workpiece；The correction of three axis is later developed into, axis becomes trunnion axis.

Patent CN201410405107.4 discloses a kind of valve straightener of three axis correction, and the principle of alignment is in fact It is that three axis squeeze bar portion so that bar portion can be deformed upon according to design requirement；Pan portion is squeezed with correction cone pulley so that two simultaneously The form tolerance at a position can be improved.
