Concentricity measuring instrument stabilizing bracket

Abstract

The invention belongs to the technical field of measuring instruments, and provides a concentricity measuring instrument stabilizing bracket. The concentricity measuring instrument stabilizing bracketcomprises a bottom plate; the upper portion of the bottom plate is connected with a bracket plate through a rough adjusting structure, the bracket plate is connected with an instrument fixing plate through a fine adjusting structure, the instrument fixing plate is slidably connected with an instrument body through an instrument bottom plate, and the interior of the bottom plate is provided with astabilizing structure; the stabilizing structure comprises a suction cup of which the middle is provided with an air extraction pipe, the top of the air extraction pipe is connected with an air extractor, the air extractor is fixed into a limiting plate, and the side surface of the suction cup is provided with an air exhaust hole; the fine adjusting structure comprises a fine adjusting assembly,a second fine adjusting assembly and a third fine adjusting assembly; and the instrument fixing plate is provided with a plurality of fixing grooves, and the instrument bottom plate is slidably connected with the fixing grooves through fixing pieces. Thus, the concentricity measuring instrument stabilizing bracket can achieve fine adjusting of the height and angle of a concentricity measuring instrument and is suitable for the working conditions high in measuring requirement, and meanwhile, the bracket moving situation can be avoided.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a stable support for a concentricity measuring instrument. Background technique [0002] The concentricity measuring instrument is used to find the concentricity of two axes of centrifugal pumps, compressors, fans, generators and other rotating equipment. It is widely used in petrochemical, power generation, papermaking, textile and machinery industries. It has reasonable structure and high precision. , small error, wide range of application, easy to use and maintain, etc., it is an ideal special measurement tool. During the use of the concentricity measuring instrument, it is usually necessary to adjust the height and angle according to the actual situation, and then measure the concentricity of the parts. [0003] CN206959880U discloses a kind of erecting support for concentricity measuring instrument, comprising bottom platform, supporting column and adjusting s...

AI Technical Summary

Problems solved by technology

Both of these two published patents can adjust the height and inclination of the concentricity measuring instrument, but the adjustment accuracy is not high. When the concentricity measuring instrument needs to be fine-tuned during use, the above two patents cannot meet the requirements; In addition, when the concentricity measuring instrument is measuring, if the bracket moves due to collision or slippery ground, it will affect the measurement results of the concentricity measuring instrument and even need to stop the measurement and reposition the bracket. The content disclosed in the above patent does not solve this problem. question

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
