Abstract

This invention discloses one guyed photoelectric displacement sensor in two dimensions for detecting the plane mobile position. By using polar coordinates it is combined by the photoelectric linear displacement sensor devices and optoelectronic devices angular displacement sensor, which includes guyed, guyed mouth, desilting of silk, guyed disk, disk spring, Ratchet, gear group, switching round of photoelectric intermittent, linear displacement fretting photoelectric switches, photoelectric switches Fretting angular displacement, micro-stepper motor, brakes, chassis planes and the base chassis. By using the photoelectric interrupter as the sensor signal source this invention satisfy the demand of the fields in civil construction, machining, equipment installation, automatic control, defense technology and scientific experiments and son on with its characteristic of high precision, large range and digital signal output.

Description

technical field [0001] The invention relates to a displacement sensor for measuring the plane moving position of an object, in particular to a pull-wire photoelectric two-dimensional displacement sensor. technical background [0002] At present, the existing mechanical, resistive, capacitive, inductive and photoelectric displacement sensors can only measure the displacement of an object in one dimension. If you want to measure the displacement in the two-dimensional direction of the plane movement of the object, you must use two one-dimensional displacement sensors arranged perpendicular to each other to measure. Not only does the sensor have high installation requirements and takes up a lot of space, but it is also very inconvenient for high-precision and large-range displacement measurement. Contents of the invention [0003] Aiming at the deficiencies of existing displacement sensors, the present invention proposes to assemble the improved pull-type photoelectric line ...
