Abstract

The invention relates to a complex curved face grinding and polishing system and method. The system comprises a three-degree-of-freedom manipulator, a visual detection device, a vibrating sensor and a three-degree-of-freedom tool platform. An installation clamp is arranged at the tail end of the manipulator and can install an oilstone, a polishing wheel and a grinding wheel. The visual detection device comprises a laser generating device and a binocular camera, is installed on the manipulator, and detects the outline and roughness of a workpiece. During working, the workpiece is installed on the three-degree-of-freedom tool platform. The visual detection device guides the manipulator to scan the outline of the workpiece, a three-dimensional outline data model is generated, and the roughness is analyzed. Polishing or grinding setting can be conducted on a work station. During grinding, setting can be conducted in three modes that a referential three-dimensional data model is compared with an actually measured workpiece three-dimensional data model, modification is conducted on the actually measured three-dimensional data model with a drawing tool, and grinding data are directly set on the actually measured three-dimensional data model.

Description

technical field [0001] The invention relates to a grinding and polishing system, in particular to a grinding and polishing system and method for complex curved surfaces based on visual information. Background technique [0002] In manufacturing, workpieces are often ground and polished. When the shape of the workpiece is simple or regular, the corresponding grinding work can be completed with a CNC machine tool or a grinding machine. However, when the shape of the workpiece is a complex curved surface, it must be done manually, and there are high requirements for the proficiency of the operator. [0003] Applying the flexibility of robots to perform grinding work is a path to solve the automation of complex surface grinding and polishing. The document "Robot Grinding System Based on Complex Space Surface Processing" (Hong Yunfei et al., China Mechanical Engineering, 2006: 150-153) uses a laser range finder to measure the surface of the workpiece, and uses a six-degree-of-f...
