Blade grinding and polishing process of industrial robot based on abrasive belt grinding and polishing machine

Abstract

The invention discloses a blade grinding and polishing process of an industrial robot based on an abrasive belt grinding and polishing machine. The blade grinding and polishing process comprises the steps that off-line programming is performed based on a CAD (Computer Aided Design) model of a blade; coordinate systems of the grinding and polishing machine and a scanner are calibrated; a grinding and polishing program is debugged on site; materials are fed by a feeding cart; the blade is clamped by the robot; the blade is scanned by the scanner; scanning results are matched with standard point cloud information; a coordinate system of a workpiece is updated; coarse grinding is performed on the blade by the grinding and polishing machine; fine grinding is performed on the blade by the grinding and polishing machine; fine grinding is performed on the inlet and outlet air sides of the blade by the grinding and polishing machine; the blade is polished by the grinding and polishing machine; the inlet and outlet air sides of the blade are polished by the grinding and polishing machine; the blade is discharged onto a discharge cart by the robot; the grinding and polishing quality of the blade is detected. The blade grinding and polishing process has the advantages of high degree of automation, safety, stability, high efficiency, high flexibility and convenience in operation, the consistency of the product quality is easy to guarantee, the processing efficiency and the processing quality are increased, the unqualified rate of blades is reduced, an existing processing mode is reformed, and the labor force is liberated.

Description

technical field [0001] The invention relates to the technical field of blade grinding and polishing, in particular to an industrial robot blade grinding and polishing process based on an abrasive belt grinding and polishing machine. Background technique [0002] With the advancement of modern science and technology and the advancement of industrialization, the fields of aerospace and energy equipment have been greatly developed. Blades are the core components of energy conversion in aerospace engines, steam turbines and wind turbines. Their machining accuracy and surface quality have a crucial impact on the performance of these machines. Therefore, the machining of blades is particularly important. Usually, after the blade is milled, it needs to be ground and polished to remove a certain allowance, and it needs to meet the surface quality requirements. At present, the grinding and polishing process in production enterprises is mainly done manually by workers, and repeated m...

Problems solved by technology

However, the manual grinding and polishing of blades has the following disadvantages: 1. The efficiency is low (only 3-4 pieces can be completed by manual grinding and polishing in 8 hours), which cannot meet the higher and higher efficiency requirements; Waste products are produced, and it is difficult to ensure good consistency of product quality (roughness is between Ra0.8-1.6); 3. Metal dust and noise generated by grinding and polishing will still cause huge safety hazards to operators
