The utility model discloses a kind of thickness detection devices for optical communication module parts, belong to optical communication module technical field, including base, fixedly connected with scale on the base, measuring device is arranged outside scale, the front of measuring device is fixedly connected with irradiation device and auxiliary device, measuring device includes moving plate, and moving plate is arranged outside scale.This utility model, after the workpiece to be measured is accurately placed on base positioning surface, slowly release clamping plate, when pressing plate is vertically downward along scale under gravity, when the lower surface of pressing plate and the upper surface of workpiece are completely contacted, moving plate stops movement, the relative position of moving plate on scale at this time is the thickness value of workpiece, by directly reading the scale line corresponding to the edge of moving plate on scale, intuitive, accurate thickness measurement result can be obtained, entire measurement process does not need additional power source, relies on gravity to realize automatic positioning.
