Description

Technical Field

[0001] The utility model relates to the field of diameter gauges, in particular to a laser diameter gauge. Background Art

[0002] The working principle of traditional laser diameter gauges is well known. The laser scanning diameter gauge system uses a light beam emitted by a laser to pass through a polygonal scanning mirror and a scanning optical system to form a continuous high-speed scanning beam parallel to the optical axis. The workpiece placed in the measurement area is scanned at high speed and received by a photoelectric receiver placed opposite the workpiece. The light projected onto the photoelectric receiver is blocked when the light beam scans the workpiece. Therefore, by analyzing the signal output by the photoelectric receiver, data related to the diameter of the workpiece can be obtained. In this way, generally only the size of circular objects can be tested. Generally, when a diameter gauge is used for measurement, it can only measure stationary objects, or the diameter gauge can be rotated for measurement. However, the rotating parts require an uninterrupted supply of electricity. The traditional structure for providing power to the rotating parts is generally a slip ring. The traditional slip ring has a complex structure, is easy to wear, and is difficult to install. Utility Model Content
