摘要：L32/40属于我公司新开发研制的大型柴油机，阀座精研跳动检具用于检测气缸盖安装阀座精研加工之后对于导管孔的跳动值。该检具的设计思路为将检具固定在定位棒上，通过自身旋转机构旋转一周，完成阀座跳动值的测量。

Abstract: The large-sized 3240 model
is a diesel engine latest developed by Weichai. The runout measurement tool is
used to measure the runout value of the valve seat to the valve guide after the
valve seat has been fit and lapped with the cylinder head. Being designed to be
secured onto a solid bar, the tool is to measure the runout value by moving one
circle by its rotating mechanism.
