A kind of centering device and centering method of code disc

Abstract

The invention provides an encoding disc aligning device. The encoding disc aligning device comprises a base (1) and a bearing chamber arranged at the center of the base (1); the encoding disc aligning device further comprises a rotating shaft (2) of which the bottom extends into the bearing chamber and an encoding disc (3) which sleeves the top of the rotating shaft (2); and the base (1) is provided with an aligning device which is located at the horizontal direction side of the rotating shaft (2) and can move in a horizontal direction so as to adjust eccentric magnitude between the center of the encoding disc (3) and the center of the rotating shaft (2). With the encoding disc aligning device of the invention adopted, quantitative adjustment of the eccentric magnitude of the encoding disc in an installation process can be effectively realized; requirements for the working skills of workers in an encoding disc aligning process can be effectively decreased, and work efficiency can be improved; and the working performance and measuring accuracy of a photoelectric encoder can be effectively ensured. The invention also relates to an encoding disc aligning method using the device.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and in particular relates to a code disc centering device and a centering method. Background technique [0002] The photoelectric encoder is a kind of angle measuring equipment integrating light, mechanics and electricity. It converts optical signals into electrical signals through mechanical structure and signal processing circuit, so as to realize the direct or direct measurement of various physical quantities such as diagonal displacement, position and speed. indirect measurement. Among them, the eccentricity of the code disc will directly affect the working performance and measurement accuracy of the photoelectric encoder, which is the core element of production control. Therefore, the correct installation method of the code disc is an important guarantee for the normal operation of the encoder. Existing encoder manufacturers generally adjust the eccentricity of the code disc by work...
