Abstract

The invention belongs to the field of intelligent instruments and devices and relates to a high-speed laser internal diameter detection system. The good detection effect of laser on surfaces of objects such as metal is utilized, and relative coordinate information of the measurement point position of a detected internal diameter is obtained using a laser triangulation method. In order to ceaselessly, effectively and stably 360-degree collect various data required in internal diameter detection, a laser range finding probe is innovatively combined with a slip ring, so that the laser range finding probe can be directly connected to a motor and achieves 360-degree high-speed rotation. A high-precision electric control linear guide rail is utilized to achieve comprehensive acquisition of internal diameter data, thereby conducting high-precision internal diameter measurement. Through verification, the laser internal diameter detection method meets requirements of internal diameter nondestructive testing, a host computer platform is friendly, and correlated data can be fed back remotely and wirelessly. The measurement method provided by the method can be popularized into other high-precision dimension detection systems capable of reflecting object internal walls.

Description

technical field [0001] The invention belongs to the field of intelligent instruments and devices, and relates to a high-speed laser inner diameter detection device, especially in the detection of defects in the inner diameter of oil drilling pipelines and the detection of various special-shaped inner diameters. Background technique [0002] As an important part of bore diameter detection, inner diameter detection has always been the focus and difficulty of detection. The high-precision detection of inner diameter has important applications in industries such as oil drilling and weapon barrels. Although there are some internal diameter detection technologies at home and abroad, they generally have disadvantages such as poor detection accuracy, low detection efficiency, and need to consume a lot of manpower, which can no longer meet the requirements of today's modern production lines for automatic production. Domestic and foreign scholars' research on inner diameter detection ...
