A blade automatic grinding and polishing method, device, electronic equipment and readable storage medium

Abstract

This application discloses a blade automatic grinding and polishing method. In order to solve the defects of the existing technology, this application processes the signal step existing in the original control signal through the simulated annealing particle swarm optimization algorithm. The simulated annealing particle swarm optimization algorithm is integrated While the simulated annealing algorithm and the particle swarm optimization algorithm have both advantages, they also remove the defects of the two as much as possible. Through the ability of the simulated annealing particle swarm optimization algorithm to find the global optimal solution, the original control can be reduced to the greatest extent. The signal step amplitude in the signal, and the reduction of the signal step amplitude will also lead to a smoother change of the excessive state force, with higher stability and robustness, so as to reduce damage to the blade and improve the performance of the blade Purpose. The application also discloses an automatic blade grinding and polishing device, electronic equipment and a readable storage medium, which have the same beneficial effect.

Description

technical field [0001] The present application belongs to the technical field of blade automatic processing, and more specifically relates to a blade automatic grinding and polishing method, device, electronic equipment and readable storage medium. Background technique [0002] The surface accuracy and surface quality of the blades used in industrial occasions directly affect their working performance. At present, more than 90% of the grinding and polishing of most types of blades in China still use manual grinding and polishing, but the consistency of manual grinding and polishing is poor, the quality cannot be guaranteed, and the processing efficiency Low; and the working environment of manual grinding is very harsh, with a lot of dust and high toxicity, sharp and noisy machine noise, repetitive and boring mechanical operations, easy to make fatigue and sleepiness, and has a great degree of damage to the health of grinding operators. In addition, the profile of the blade i...

Problems solved by technology

The processing quality of the profiling method depends on the accuracy of the template. The manufacturing accuracy and running loss of the template will affect the final forming quality of the blade, and its versatility is poor, so it is difficult to meet the processing requirements of small batches and multiple specifications of blades.

Multi-axis linkage universal CNC grinding equipment has good flexibility and high precision, but it is limited by the high price of foreign high-end CNC equipment, the lack of functions of domestic alternative products, and the difficulty of process programming, it is difficult to quickly convert processes, and the lack of "measurement-processing "Adaptive closed-loop processing capabilities and other reasons have not replaced manual grinding and polishing, and have been widely used

[0004] The robot has a large movement space, intelligence, low cost, and fast and flexible process conversion. It has significant advantages in realizing multi-variety, small-batch grinding and polishing of aircraft blades; Slow, low positioning accuracy, low stiffness and large changes with the pose, which seriously affects the shape and position accuracy of blade processing

Robot abrasive belt grinding and polishing requires the robot to hold the blade and the abrasive belt wheel for contact operation, which is limited by factors such as modeling error, controller performance and uncertainty, which usually leads to errors in motion control, and it is difficult to obtain accurate information about the contact environment , simple motion control is not only difficult to complete contact applications, but may even easily lead to contact impact and excessive contact force, resulting in serious blade deformation and damage
