Problems solved by technology

At present, the two φ4 positioning pin holes in the 6 fuel holes on the air intake surface of the 6J cylinder head are difficult to measure because of the long hole depth and small diameter, and there is no suitable measuring tool on the machining site.
When the product is sent to the three-coordinate measurement, due to the short length and large diameter of the three-coordinate measuring instrument, it is impossible to use the three-coordinate measuring instrument to directly measure the position of the two φ4 pin holes, which seriously restricts the quality of the cylinder head fuel hole position. judgment, which in turn will affect the production of the cylinder head line

Abstract

The invention discloses a tool for detecting the location degree of a positioning pin hole of a fuel hole of a cylinder cover. The tool comprises a main body, a handle and a measuring rod, the handle is coaxially connected with one end of the main body; the measuring rod is vertically connected with the end surface of the other end of the main body; wherein the measuring rod is used for being inserted into a cylinder cover fuel oil hole positioning pin hole for detection. The tool for detecting the location degree of the positioning pin holes of the fuel hole of the cylinder cover can quickly measure the location degree of the two phi 4 positioning pin holes in the high-pressure fuel hole of the cylinder cover, can quickly measure and judge whether the positioning pin holes are qualified or not online without using various measuring tools and through multiple conversions, realizes quick measurement and accurate judgment, and improves the working efficiency. And the production efficiency is improved while the detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of engine manufacturing, in particular to a detection tool for the position degree of a positioning pin hole of a fuel hole of a cylinder head. Background technique [0002] The 6J cylinder head needs to perform three inspections during the processing to ensure that the dimensions meet the requirements of the drawings. In the process of three inspections, in order to accurately and quickly measure the position of the fuel hole, a simple and suitable measuring tool is required. . At present, the two φ4 locating pin holes in the six fuel holes on the intake surface of the 6J cylinder head are difficult to measure due to the long hole depth and small diameter, and the lack of suitable measuring tools on the machining site. When the product is sent to the CMM, due to the limitation of the short length of the probe head and the large diameter of the CMM, the CMM cannot be used to directly measure the position of the two φ...
