Abstract

The invention discloses an online grinding quality control system based on laser sensing. The system comprises a grinding module, the grinding module comprises grinding heads, a spacial six-degree-of-freedom motor electrically connected with the grinding heads and a gearbox connected with a main shaft of the spacial six-degree-of-freedom motor, and the grinding heads are assembled on an output shaft of the gearbox; the online grinding quality control system further comprises a roughness measuring module for measuring the roughness of a ground plane which is ground just now, and the roughness measuring module comprises a laser pulse generator, a grating capable of adjusting the luminous flux and a laser receiving sensor. The invention further discloses an online grinding quality control method based on laser sensing. The online grinding quality control system and method based on laser sensing can achieve online grinding quality detection and online control adjustment and improve the grinding production efficiency and the grinding quality.

Description

technical field [0001] The invention relates to an online grinding quality control system and control method based on laser sensing, belonging to the technical field of mechanical manufacturing. Background technique [0002] With the rapid development of China's high-speed train rail transit, welding is a key technology in rail transit. The quality of welding also determines the quality of high-speed train vehicles to a certain extent. The high weld reinforcement is likely to cause stress concentration and reduce the bearing capacity of structural parts. , the fatigue life is reduced, and even threatens the safety of the train in service. At present, the automation level of the grinding industry is low, and the commonly used grinding method is mainly manual grinding. The grinding quality is largely restricted by the experience and technology of the grinding workers. The grinding environment is harsh, the work intensity is high, time-consuming, and the efficiency is low. Dus...
