Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing

[0015] like figure 1 As shown, the dial indicator 1 is installed on the inspection body, and the nut is tightened on the inspection body 3, and the compression contact of the dial indicator contacts with the upper groove of the convex plunger shaft 7 inside the inspection body. During the inspection, the inspection body Installed in the hole of the injector is a compression inspection specific thimble to read the reading of the dial indicator.

[0016] The upper part of the inspection body fixes the dial indicator by tightening the nut 3 and the dial indicator locking seat 2; There is a "U" groove 9 on the plug shaft to the thimble, and by tightening the screw 8, the size of the positioning shaft 10 of the injector hole at the lower part of the plunger sleeve 5 of the inspection body, the size of the thimble 11 and the size of the cylinder head injector are designed.

Abstract

The invention discloses a gauge for detecting the protruding volume of a cylinder cover oil injector hole. The gauge comprises a gauge body, a dial indicator and a correcting block. When the gauge is used for measuring, a gauge oil injector positioning shaft and the cylinder cover oil injector hole are positioned, a gauge body ejector pin is made to extend out of the cylinder cover oil injector hole, and the ejector pin is ejected through the correcting block. The gauge further comprises a plunger bushing, the dial indicator is connected with a plunger shaft, and the plunger shaft comprises a hold-down nut and a tightening nut. The gauge for detecting the protruding volume of the cylinder cover oil injector hole is simple in structure, convenient to use and capable of quickly detecting the protruding volume of the cylinder cover oil injector hole, so that the performance and quality hidden danger of poor atomization, incomplete combustion, high temperatures and the like in the operation process of a motor due to the machining deviation of the protruding volume of the cylinder cover oil injector hole is avoided.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to a checker for detecting the protruding amount of the injector hole of the cylinder head. Engine combustion system failure caused by machining errors. Background technique [0002] The cylinder head is the main fixing part of the diesel engine. The fuel injector hole on the cylinder head is divided into direct mounting type and oblique mounting type. The tolerance of the end face of the fuel injector mounting hole to the body joint surface (large face) of the cylinder head seriously affects the combustion process of the diesel engine. Combining the common engine faults that appear in the market every year: incomplete combustion, poor atomization of the injector, high exhaust temperature and other faults, such problems are only solved by replacing the injector during routine maintenance. In addition to quality problems, the protruding length from the injector nozzle is rarely analyze...
