喷油嘴针阀体中孔圆度在线测量系统的研究

On-line Measurement for Bore Roundness of Nozzle Needle Valve Body

针对目前喷油嘴针阀体中孔磨削不能实现中孔圆度在线测量的问题,研发了一套针阀体中孔圆度在线测量系统。论述了组成该在线测量系统的三部分:即气动测量系统部分、机械系统部分以及控制系统部分。

When grinding the bore of the nozzle needle valve body, bore roundness cannot be measured on - line. To solve this problem, on -line measurement for bore roundness of nozzle needle valve body is studied. This paper introduces three part of this on - line measurement ： the part of pneumatic gauging, the part of mechanical system and the part of control system.
