Description

[0002] In the current social development, the production and processing of continuous square materials has become quite popular. However, with the development of industry, people have higher and higher requirements for the precision of the outer dimensions of square materials. Low-precision square materials can no longer meet people's daily needs. High-precision square materials often become people's new favorites. Therefore, manufacturers need to continuously measure the outer dimensions of continuous square materials during the processing and production of square materials to ensure that they can meet certain precision requirements. However, the current technical level of the measurement of the outer dimensions of square materials is still limited to accurate dimension measurement by calipers or go / no-go gauges in static state, and it is impossible to measure the precise outer dimensions of square materials in the non-stop continuous production process. Even by using a laser diameter gauge, it can only measure the dimensions of a specific position and cannot measure the dimensions of the entire square cross section. It is an inevitable trend for technicians in this field to develop a laser ranging square tube measuring device that can measure the precise outer dimensions of square materials in the non-stop continuous production process of the production line.
