Non-contact sensor position adjusting structure for measuring shafts

Abstract

The invention discloses a sensor position adjusting mechanism for non-contact measurement of shaft parts. The sensor position adjusting mechanism for non-contact measurement of the shaft parts comprises an equipment measuring basis, a fixing assembly, a translation assembly and a rotating assembly, wherein the fixing assembly is fixedly installed on the equipment measuring basis; the translation assembly is installed and fixed on the fixing assembly in an up-down lifting adjustment mode; and the rotating assembly is installed on the translation assembly in a relatively rotating mode. According to the sensor position adjusting mechanism for non-contact measurement of the shaft parts provided by the invention, two adjustments of translation and rotation are alternately used, so that the final error can be converged to a relatively small value, and high-precision adjustment of a measurement point is realized; and the structure provided by the invention is beneficial to reducing the process requirements on processing and assembling, and is easy to popularize.

Description

technical field [0001] The invention relates to a sensor position adjustment mechanism, in particular to a non-contact sensor position adjustment structure of a measuring shaft. Background technique [0002] When non-contact measuring sensors are used to measure parameters such as the outer diameter and circular jump of the shaft, the installation position of the sensor is closely related to the measurement accuracy. Generally, the measurement path of the sensor must pass through the axis of the shaft, that is, the center of the section, otherwise it will lead to incorrect measurement. accurate, resulting in measurement failure. At this stage, there is no mature solution to this kind of problem. Generally, manual adjustment is used for adjustment, or machining is used to ensure the accuracy of the installation position, which leads to low measurement accuracy and poor reliability. Contents of the invention [0003] In order to solve the deficiency of the background techno...
