Sensor installation hole detecting tooling of explosion pressure sleeve

Abstract

The invention discloses a sensor installation hole detecting tooling of an explosion pressure sleeve. The sensor installation hole detecting tooling comprises a detecting head pull rod and an installation hole detecting head, wherein the detecting head pull rod is of a stepped shaft structure, and comprises a first large shaft at the upper part and a first small shaft at the lower part of the first large shaft; a first axial threaded connection hole is formed in the top part of the first large shaft; the diameter of the first small shaft is smaller than that of an inner cavity of the explosion pressure sleeve; the installation hole detecting head is of a stepped shaft structure, and comprises a second large shaft at the upper part and a second small shaft at the lower part of the second large shaft; the top part of the second large shaft is fixedly connected with the lower end of the first small shaft, and the second large shaft is adaptively inserted in a large hole of a qualified explosion pressure sleeve; and the second small shaft is adaptively inserted in a small hole of the qualified explosion pressure sleeve. The detecting tooling can judging whether size and coaxiality of the sensor stepped installation holes of the explosion pressure sleeve conform to use requirements quickly and accurately, and promotes the progress of pilot development.

Description

technical field [0001] The invention relates to the field of machining dimensions and coaxiality inspection of sensor installation holes of explosion pressure sleeves, in particular to a sensor installation hole detection tool of explosion pressure sleeves. Background technique [0002] In the diesel engine industry, during the test development process, it is necessary to detect the explosion pressure in the cylinder, so it is necessary to use an explosion pressure sensor and an explosion pressure sleeve assembly for installing the explosion pressure sensor. [0003] The stepped inner hole in the "explosion pressure sleeve" used to install the "explosion pressure sensor" is difficult to process. The stepped inner hole is a deep hole and small hole structure, and after the parts are processed, it is impossible to measure the stepped inner hole with conventional measuring tools. Check the dimensions and concentricity. Therefore, the quality of the explosion pressure sleeve ca...

[0003] The stepped inner hole in the "explosion pressure sleeve" used to install the "explosion pressure sensor" is difficult to process. The stepped inner hole is a deep hole and small hole structure, and after the parts are processed, it is impossible to measure the stepped inner hole with conventional measuring tools. The size and concentricity of the

Therefore, the quality of the explosion pressure sleeve cannot be guaranteed, and sometimes the "explosion pressure sensor" cannot be installed in place during use, so the sensor will be crushed when the "explosion pressure sensor" is pressed

The "explosion pressure sensor" is an imported part, which is expensive, and the damage caused by the above reasons causes a waste of funds

[0004] At this time, the "explosion pressure sleeve" must be removed and replaced until it is replaced with a qualified "explosion pressure sleeve", which causes a waste of manpower and time and affects the progress of test development
