Abstract

The invention discloses a deep hole inner diameter measuring system which comprises a measuring main body moving in the axial direction of a deep hole and a measuring control device connected with the measuring main body. The measuring main body comprises a cavity, at least three rows of supporting rolling wheels, at least two stopping balls and a rotating measuring disc, wherein the supporting rolling wheels are evenly distributed outside the cavity, one supporting rolling wheel is provided with a driving wheel for driving, the stopping balls are evenly distributed outside the cavity, the rotating measuring disc is arranged at one end of the cavity, a plurality of eddy current displacement sensors for measuring the inner diameter of the deep hole are arranged in the radial direction of the rotating measuring disc, and the eddy current displacement sensors are designed to achieve high sensitivity of 20 mv/micrometer within the 1mm measuring range on the basis of the simple series resonance principle. The stopping balls, the driving wheel and the rotating measuring disc are driven by corresponding driving devices respectively. The measuring control device comprises a first control module, a second control module, a third control module and a measuring calculation module for processing voltage signals output by the eddy current displacement sensors and calculating the inner diameter of the deep hole. According to the system, the inner diameter of the deep hole can be measured, and the measuring precision of the inner diameter of the deep hole can be improved.

Description

technical field [0001] The invention relates to the technical field of hole inner diameter measurement, and more specifically, relates to a deep hole inner diameter measurement system. Background technique [0002] The fields of national defense, military, industrial production and scientific research have a wide range of requirements for the measurement of the inner diameter of holes, especially deep holes (more than 3m in depth), such as the measurement of the inner diameter of artillery pipelines, the measurement of the inner diameter of deep holes in hydraulic power systems in construction machinery, and oil drilling. Pipe inner diameter measurement, inner diameter measurement of long pipes for fluid research, etc. With the advancement of science and technology, the requirements for the measurement of the inner diameter of deep holes are getting higher and higher. For example, the accuracy higher than 10μm / 50mm is required, and it should be measured at the processing sit...
