Abstract

The invention discloses a device for measuring the coaxiality of an oil injector installation hole and an oil injector head installation hole of a cylinder cover. The device consists of an expansion mandrel, a handle, expansion balls, expansion ball installation holes, compression springs, a front rod, a measuring rod installation groove, a screw, a dial test indicator, a measuring rod and a measuring head. The expansion mandrel slides in the oil injector installation hole of the cylinder cover in all directions according to the measuring requirement, and simulates the axis of the oil injector installation hole of the cylinder cover; the highest reading of the inner diameter of the oil injector head installation hole is measured by using the lowest reading of the inner diameter of the oil injection installation hole, which is measured by the dial test indicator, as reference; the device for measuring the coaxiality of the oil injector installation hole and the oil injector head installation hole of the cylinder cover is novel in design and structure, simple in measuring process, and convenient to use; and a measuring result is accurate.

Description

technical field [0001] The invention relates to a measuring device for mechanical parts, in particular to a measuring device for the coaxiality between the installation hole of the fuel injector of the cylinder head and the installation hole of the fuel injection head. Background technique [0002] At present, the coaxiality of the installation hole of the cylinder head fuel injector to the installation hole of the fuel injection head is an important quality item affecting the performance of the cylinder head; qualitative measurement with plug gauges can only judge whether the parts are qualified, and cannot provide data to guide the processing technology in detail Improvement affects the quality of parts; using three-coordinate detection, the measurement procedure is complicated and the cost is high. Contents of the invention [0003] The invention provides a measuring device for the coaxiality between the installation hole of the fuel injector of the cylinder head and th...
