High-precision rolling displacement detecting device

Abstract

The invention discloses a high-precision rolling displacement detecting device comprising a rolling wheel roller, a rolling bearing, a friction wheel, a coded disk and a displacement output part, wherein the rolling wheel roller is connected with the rolling bearing and the friction wheel and is supported by the roll bearing to drive the friction wheel to rotate; the front of the friction wheel is connected with a small shaft part of the rolling wheel roller through the rolling bearing; the rear of the friction wheel is connected with the coded disk and transmits the output rolling displacement to the coded disk in a form of the friction force; the coded disk and the friction wheel are connected with the displacement output part through a signal wire; and the connection among the rolling wheel roller, the rolling bearing and the friction wheel is realized by the small shaft part of the rolling wheel roller. The device has the characteristics of scientific concept, simple structure, low cost, high speed and high precision; and the rolling displacement is detected by the coded disk in a pulse manner. The high-precision rolling displacement detecting device can be applied to the fields of industries and control, such as industrial scanning and imaging equipment, high-precision driving equipment, and the like and has broad market prospect and high application value.

Description

technical field [0001] The invention relates to a high-precision rolling displacement detection device, which can accurately detect and output the displacement generated by rolling, can be widely used in industrial and control fields such as industrial scanning imaging equipment, high-precision transmission equipment, etc., and belongs to the fields of information processing and industrial control. Background technique [0002] Motion displacement detection is an important technology in the field of industry and control, and accurate rolling displacement detection is the key to precise control in industrial products. For example, in high-speed and precise scanning, the scanning imaging component or scanning area must move quickly to produce the imaging range required for scanning imaging, which is the key technology of scanning imaging. However, the movement of the scanning imaging component or the scanning area usually drives the rotation of the related bearing fixing compo...

Problems solved by technology

However, in many special environments (high-precision scanning imaging, high-speed smooth motion, etc.) or harsh environments (such as high temperature, corrosion, etc.), it may not be possible to directly install displacement detection sensors within the range of motion, which requires converting motion displacement into rolling motion. Displacement and achieve the purpose of detecting motion displacement by detecting rolling displacement
