Apparatus for detecting pressure of combining surface in interference fit of shaft sleeve and usage method thereof

Abstract

The invention discloses an apparatus for detecting the pressure of a combining surface in interference fit of a shaft sleeve and a usage method thereof. The apparatus comprises a water tank, the watertank is fixedly arranged on a horizontal movement traverse plate of an automatic tri-axial platform machine; walls of the left side and the right side of the water tank are provided with through holes in mirror symmetry, the internal part of the through hole at the left side of the water tank is provided with a left transmission shaft in a penetrating manner, the right end of the left transmission shaft extends to the internal part of the water tank and is fixedly connected with a single-diaphragm coupling, the left side of the left transmission shaft is provided with a first universal indexplate, the internal part of the through hole at the right side of the water tank is provided with a right transmission shaft in a penetrating manner, the left end of the right transmission shaft is fixedly connected with a single-diaphragm coupling, the right side of the right transmission shaft is provided with a second universal index plate, and the single-diaphragm couplings at the left side and the right side are both connected with an empty sleeve clamp body. According to the apparatus, the detection error is reduced, the detection precision is improved, the structure of the detection apparatus is optimized, the dismounting is more convenient, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of ultrasonic detection, in particular to a device for detecting the pressure of an interference fit joint surface of a shaft sleeve and a use method thereof. Background technique [0002] In the development of the machinery industry, the contact condition of the joint surface of the shaft sleeve affects the performance of the assembly to a large extent, so the detection of the pressure of the joint surface is becoming more and more important and urgent, but due to the closedness of the joint surface of the shaft sleeve , making it difficult to detect the magnitude of the pressure, and the traditional thin-film sensor not only often fails to meet the requirements for detection accuracy, but also changes the original contact condition of the joint surface during the detection process, resulting in a large error. On the other hand, the past The device used to detect the fit of the shaft sleeve usually places the shaft s...

[0002] In the development of the machinery industry, the contact condition of the joint surface of the shaft sleeve affects the performance of the assembly to a large extent, so the detection of the pressure of the joint surface is becoming more and more important and urgent, but due to the closedness of the joint surface of the shaft sleeve , making it difficult to detect the magnitude of the pressure, and the traditional thin-film sensor not only often fails to meet the requirements for detection accuracy, but also changes the original contact condition of the joint surface during the detection process, resulting in a large error. On the other hand, the past The device used to detect the shaft sleeve fits the shaft sleeve vertically, which may also cause eccentricity when adjusting the angle and inconvenience when disassembling the device.
