The invention discloses a fault detecting device for an incremental grating ruler and a detecting method thereof. The fault detecting device for the incremental grating rule comprises a mechanical part, a microcomputer system and an electric control system. The fault detecting device for the incremental grating ruler and the detecting method thereof are suitable for detecting the incremental grating ruler with faults, and corresponding adjustment is carried out on a grating ruler circuit by utilizing measured signal data to enable output signals to reach allowed values. A scaleplate grating and a reading head of the incremental grating ruler are mounted on a rack and a grating reading head mounting sliding plate respectively, a screw rod mechanism drives the grating reading head mounting sliding plate to move relative to the rack along a guide rail, the reading head of the incremental grating transmits measuring signals to the microcomputer system for processing, and corresponding adjustment is carried out on the grating ruler circuit according to the measured signal data. The fault detecting device for the incremental grating rule is simple in structure, convenient to mount and maintain, simple in using method and suitable for incremental grating rulers of different specifications.
Description
Technical field [0001] The invention relates to a fault detection device, in particular to an incremental grating ruler fault detection device and a detection method thereof. Background technique [0002] The grating ruler, also called the grating ruler displacement sensor, is a very important measuring device that can measure linear and angular displacement. Grating rulers are widely used in machine tools and current machining centers and measuring instruments, especially in CNC machine tools and precision machining industries occupy a very important position. Due to its large measuring range, high measuring accuracy, and sensitive response, the grating ruler has gradually become an indispensable device in the manufacturing industry. [0003] The grating ruler is so important to the machine tool. If there is a problem with the grating ruler of the machine tool, it is equivalent to a person's eye problem. If it is not corrected in time, the impact on the work will be very large. ...
