Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] There are few methods for measuring the runout of the shafting in the prior art, and the measurement method is realized by placing a ball on the end face of the shafting. Due to the influence of the angular shake error of the shafting, the measurement error of the runout error of the shafting is relatively large. , and the measurement method of the angular runout and runout of the shaft system provided in the prior art is single, it cannot simultaneously...

Abstract

The application provides a compound detection device and method for shafting sway and runout, wherein the compound detection device for shafting sway and runout includes a shaft system to be measured, a plane mirror, an angle measuring device and a distance measuring device, and the angle measurement The device directly measures the shake amount of the shaft system to be measured, and combines the data of the distance measuring device to obtain the runout amount of the end face of the shaft system to be measured, thereby obtaining the runout amount of the shaft system to be measured through calculation. The shake and runout of the shaft system provided by the present invention The composite detection method does not need to search for the apex of the sphere as in the prior art, and calculates the runout of the shaft system to be measured through multiple angle data records and distance data records, which makes the detection method have high detection accuracy and can be effectively The shake and runout of the shaft system to be measured are separated to obtain a more accurate runout of the shaft system to be measured.

Description

technical field [0001] The invention belongs to the technical field of photoelectric measurement, and relates to a composite detection device and method for shaking and beating of a shaft system. Background technique [0002] In precision instruments, the angular runout error of the shafting is a small angle change, and the runout error of the shafting is a small displacement change. Angle measurement and displacement measurement are important components of geometric metrology technology. Micro-angle measurement and micro-displacement measurement are widely used in national defense construction, industrial manufacturing and daily life. Especially in the application of precision instruments, there are high requirements for the shaking and runout of the shaft system. It is of great significance to accurately and quantitatively detect the shake and runout of the shaft system for the function and performance improvement of precision instruments, especially It is very important ...
