Problems solved by technology

Commonly used non-contact measurements are based on eddy current, ultrasonic and line structured light, etc. The former two use the principle of induced current and ultrasonic detection respectively, but the accuracy is not high when measuring workpieces with spiral grooves and deep holes. The wall structure has a great influence, and there will be interference when the groove is detected, and there are unavoidable errors in data acquisition and processing, so it is difficult to complete the high-precision measurement of the geometric structure parameters of the inner wall of the spiral groove deep hole workpiece

Abstract

The invention provides a deep hole inner wall geometric structure detection robot system based on a line structured light detection method, which realizes bionic wriggling, automatically and stably moves back and forth in a spiral groove deep hole workpiece, also can control the rotating speed of a rotating detection head according to different requirements in the advancing process, and utilizes the line structure light detection principle, namely, a structure light controller emits a structured light beam to the wall of the spiral groove hole, the light beam is modulated into a deformed structure light beam under the influence of the spiral groove on the surface of the inner wall, and the deformed structure light beam is collected by corresponding CCD camera after being reflected by a plane mirror, so that complete morphology data of the complex hole wall can be detected and obtained. The detection method is not influenced by factors like workpiece shape, material, electromagnetism, vibration and the like. The system provided by the invention is unique in structure, is provided for solving the problem of spiral groove deep hole workpiece inner wall geometric structure detection, is combined with an efficient linear structure light detection principle and intelligent detection equipment, and has important significance for improving the intelligent, automatic and precise degreeof spiral groove deep hole workpiece inner wall geometric structure detection.

Description

technical field [0001] The invention relates to a deep hole inner wall geometric structure detection robot system based on a line structured light detection method, belonging to the technical field of intelligent detection equipment systems. Background technique [0002] Deep hole processing is an important branch of equipment manufacturing industry, which is widely used in military industry, aerospace, transportation, machine tools, automobiles, energy mining and other fields. Due to the special functions of deep-hole workpieces, deep-hole workpieces often become the key components that determine product quality and efficiency. Modern mechanical products have higher and higher requirements on function and structure, and the processing of deep-hole workpieces is also developing towards high precision in order to meet the requirements of use. Deep-hole workpieces have the characteristics of large length-to-diameter ratio and limited space. Usually, when testing, only rely on...
