Heat-insulating light-penetrating device

Abstract

The invention belongs to the field of optical diameter measuring, and particularly relates to a heat-insulating light-penetrating device for an optical diameter measurer. The profile of the heat-insulating light-penetrating device is of a pipe sleeve shape; heat-insulating light-penetrating lenses which can be radially transmitted by a measuring light ray are symmetrically arranged on a pipe wallof the pipe sleeve along a light ray to be measured and a bar material axis line; and mirrors of the heat-insulating light-penetrating lenses are mutually parallel and are parallel to an advancing direction of the light ray to be measured and the bar material axis line. According to the invention, the influence on measuring equipment, caused by a working complex environment of the measuring equipment, can greatly lower without influencing passing of a measuring optical path, thereby the measuring accuracy of the optical diameter measurer for which the heat-insulating light-penetrating device is suitable is enhanced.

Description

technical field [0001] The invention belongs to the field of optical diameter measurement, and in particular relates to a heat-insulating and light-transmitting device for an optical diameter measurement instrument. Background technique [0002] The present invention is suitable for optical instruments in the field of diameter measurement, such as optical diameter measuring instruments. Its specific working environment needs to seek to minimize the influence of the complex working environment on the measurement equipment without affecting the reliable measurement of the measurement equipment. [0003] The diameter measuring instrument is a measuring instrument for synchronously measuring technical parameters such as contour line degree (such as diameter roundness) in the metallurgical industry production line and bar process. When the existing caliper gauges measure the produced wires and bars, the following problems often occur with the measurement: First, because the wires...

AI Technical Summary

Problems solved by technology

When the existing caliper gauges measure the produced wires and bars, the following problems often occur with the measurement: First, because the wires and bars to be measured are all high-temperature parts, the high temperature generated around them when they travel It will greatly affect the service life of the precision measuring parts inside the caliper; secondly, due to the harsh environment of the caliper, the dust and water mist are very large, which is very easy to cause pollution to the lens of the measuring part, and then cause the caliper to fail. Normal work; Finally, during the transportation process of the newly rolled high-temperature wire and bar, the surface layer will continue to oxidize and drop scale after contacting the air, or rub against the inner tube to produce friction debris, oxide scale or friction debris Dropping on the lens of the measuring part will pollute the lens and block the light, thereby affecting the accuracy of the measured data
