Blade polishing device and method

Abstract

The invention discloses a blade polishing device and method. The blade polishing device comprises an industrial robot, a force control device, a clamping tool, a first polishing machine, a second polishing machine and a third polishing machine, wherein the force control device is installed at the end part of a mechanical arm of the industrial robot; the clamping tool is connected with the force control device; the first polishing machine, the second polishing machine and the third polishing machine are distributed around the industrial robot; the clamping tool is used for clamping a blade; theforce control device is used for adjusting the contact pressure between the blade and the polishing machines; the first polishing machine is used for polishing the profile of the blade; the second polishing machine is used for polishing the air inlet edge and the air outlet edge of the blade; and the third polishing machine is used for polishing the edge plate of the blade and is used for polishing the profile of the blade, the air inlet edge and the air outlet edge of the blade. The force control device sets the contact pressure between the blade and the polishing machines, and ensures the removal amount of different blade sections in the polishing process, and the requirements of different positions and precision of the blade are met by different stations of the polishing machines.

Description

technical field [0001] The invention belongs to the field of mechanical polishing, and in particular relates to a blade polishing device and a polishing method. Background technique [0002] The structure of the blade is complex, and the curvature of the blade shape changes greatly. After milling, the milling tool marks are removed by manual polishing and the surface roughness is improved. Manual polishing can flexibly remove the tool marks at different positions of the blade, but manual polishing depends on the experience of the workers, resulting in individual differences in the blades. Huge, unable to guarantee product consistency, low polishing pass rate (one-time inspection pass rate <30%, out-of-tolerance use <70%); some blades are difficult to polish, and only a few workers in the entire factory can perform polishing work, resulting in low production capacity , a large number of blades are backlogged in the polishing process; the effective working time of worker...

[0002] The structure of the blade is complex, and the curvature of the blade shape changes greatly. After milling, the milling tool marks are removed by manual polishing and the surface roughness is improved. Manual polishing can flexibly remove the tool marks at different positions of the blade, but manual polishing depends on the experience of the workers, resulting in individual differences in the blades. Huge, unable to guarantee product consistency, low polishing pass rate (one-time inspection pass rate <30%, out-of-tolerance use <70%); some blades are difficult to polish, and only a few workers in the entire factory can perform polishing work, resulting in low production capacity , a large number of blades are backlogged in the polishing process; the effective working time of workers is less than 4 hours (statistically based on 8 hours of working time), the production efficiency is low, and the working environment is harsh (noise, dust, darkness); polishing a blade needs to change 3 to 5 mills head, each grinding head polishes 4 to 5 leaves on average
