A thickness gauge based on laser measurement

Abstract

The application discloses a kind of thickness measuring instrument based on laser measurement, it is related to laser measurement device technical field, including base;Positioning seat is set on base;Rotary seat is rotationally connected in positioning seat;Translation seat is slidably connected in rotary seat, for placing workpiece to be measured;Measuring sensor component is set on base, for measuring the thickness of workpiece located on translation seat;Rotary drive mechanism is used to drive rotary seat rotation;And translation drive mechanism is set on rotary seat, for driving translation seat relative to rotary seat and doing horizontal reciprocating movement.In the application, workpiece is rotated by rotary drive mechanism, combined with translation drive mechanism, workpiece is horizontally moved, and "dynamic scanning" in measurement process is realized.Upper laser sensor, lower laser sensor can detect multiple different positions on the surface of workpiece, so as to effectively avoid the error caused by single-point detection or surface slope, improve the authenticity and accuracy of measurement data.
