Description

Technical Field

[0001] The utility model relates to an oil pipe joint outer diameter detection mechanism, belonging to the technical field of workpiece outer diameter detection. Background Art

[0002] The operating principle of a laser outer diameter measuring instrument is based on laser scanning measurement technology. The instrument is equipped with a high-speed rotating laser transmitter and receiver. The laser beam emitted by the transmitter is processed by a set of lenses to generate parallel light. This parallel light illuminates the workpiece on the stage horizontally. When the workpiece blocks the beam, a signal is generated on the receiver. This signal is transmitted to a dedicated computer processor via a photoelectric sensor. After calculation, the measured diameter value, roundness runout, and other parameters can be read.

[0003] At present, during the scanning measurement process of the laser outer diameter detector, the height of the scanning beam and the height of the stage are fixed, so the position of the workpiece that can be scanned is relatively constant, which makes it inconvenient to measure the outer diameter parameters of the workpiece at different positions along the longitudinal direction, resulting in inconvenience during the measurement process.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content
