Description

Technical Field

[0002] A pipe joint is a component that connects two or more pipes to achieve smooth liquid or gas transmission in industrial equipment. Usually, pipe joints are installed at both ends of the pipe for easy disassembly and maintenance. Pipe joints are widely used in industrial fields such as petroleum, natural gas, and chemicals. With the wide application of pipe joints, the processing of pipe joints has also increased. The measurement of the aperture and verticality of the pipe joint after processing is an important basis for determining the quality of the processed products.

[0003] The existing method is to manually measure the hole diameters one by one with a hole meter and to detect the verticality with a verticality measuring instrument. The other method is to mechanically measure only one hole diameter, and then change the pipe mouth of the oil pipe joint to be measured and measure it again. This measurement method has high labor costs, low work efficiency, low measurement accuracy, and cannot complete the simultaneous measurement of multiple holes. Therefore, a laser hole measuring tool for oil pipe joints is proposed. Utility Model Content
