Problems solved by technology

[0002] At present, the coaxiality measurer of the cylinder head fuel injector installation hole and the bottom plate spigot needs to use a flat plate, a mandrel, a fixed and adjustable support, a measuring frame with an indicator, etc. The measurement process is complicated and difficult. It is even more difficult to move large parts; if three-coordinate measurement is used, the cost is high and the measurement process is complicated

Abstract

The invention discloses a coaxiality measurer of a mounting hole of a cylinder cover fuel injector and the inner circle of a baseplate seam allowance, which is composed of an expanding arbor, a handlebar, expanding beads, compression springs, mounting holes for the expanding beads, a front rod, a cross slab, a hole in the lower end of the cross slab, a bolt, a hole in the upper end of the cross slab, a screw, a fixing rod, a fine dial test indicator and a test head. The sliding expanding beads contacted with the inner walls of the mounting hole for the cylinder cover fuel injector are arranged at the outer circle of the expanding arbor; and the test head of the fine dial test indicator indicates the inner circle of the baseplate seam allowance. The coaxiality measurer of the mounting hole of the cylinder cover fuel injector and the inner circle of the baseplate seam allowance has the advantages that the structure design is novel; the process of measurement is simple; and the effect of measurement is accurate.

Description

technical field [0001] The invention relates to a measuring device for mechanical parts, in particular to a measuring device for measuring the inner circle coaxiality between the installation hole of the fuel injector of the cylinder head and the seam of the bottom plate. Background technique [0002] At present, the coaxiality measurer of the cylinder head fuel injector installation hole and the bottom plate spigot needs to use a flat plate, a mandrel, a fixed and adjustable support, a measuring frame with an indicator, etc. The measurement process is complicated and difficult. It is even more difficult for moving large parts; if three-coordinate measurement is used, the cost is high and the measurement process is complicated. Contents of the invention [0003] The invention provides a measuring device for measuring the coaxiality of the inner circle of the installation hole of the fuel injector of the cylinder head and the seam of the bottom plate. The measuring head is...
