A robotic intelligent grinding and polishing method suitable for blisks

Abstract

The invention belongs to the technical field of intelligent manufacturing, and discloses a robot intelligent grinding and polishing method suitable for a blisk. The method comprises the following steps that 1, a grinding and polishing device is provided, and the blisk to be ground and polished is installed on a three-degree-of-freedom automatic clamp of the grinding and polishing device; 2, the three-freedom-degree automatic clamp is adjusted to make the blisk reach the optimal posture; 3, the grinding and polishing device starts to grind one blade of the blisk, the blade is detected after grinding is completed so as to judge whether the ground and polished surface of the blade meets requirements or not, if the requirements are not met, the grinding and polishing device grinds the part which does not meet the requirements again until the requirements are met, and if the requirements are met, step 4 is executed; 4, the grinding and polishing device continues to grind a next blade untilall the blades of the blisk are ground. According to the method, the efficiency is improved, the cost is reduced, and the machining quality is improved.

Description

technical field [0001] The invention belongs to the technical field related to intelligent manufacturing, and more specifically relates to a robot intelligent grinding and polishing method suitable for blisks. Background technique [0002] The blisk is a key component that directly participates in energy conversion in engines, gas turbines, compressors and other equipment. The surface quality after processing is very high. The overall blisk is designed by designing the blade and the disc as a whole, and it is manufactured by integral processing. Made without tenon and tenon. The radial height and thickness of the rim of the blisk are greatly reduced, the effect of weight reduction is obvious, and the escape loss of gas in the gap between the tenon and tooth roots of the split structure is eliminated, and the assembly of the blade and the disc is avoided. Failures caused by improper fretting wear, cracks, and lock plate damage are conducive to improving work efficiency and f...

Problems solved by technology

[0003] However, the processing process of the blisk is more difficult and more demanding. The grinding and polishing process of the blisk refers to removing the milling lines on the surface of the blisk to make the surface smooth. The part of the blisk to be polished has blade intake and exhaust Edges, blade inner and outer arcs, blade root corners and disc profile runners

Due to the large number of grinding and polishing parts, and the processing methods of each part are different, at present, the grinding and polishing of the whole blisk is mostly done by manual grinding and polishing, which is labor-intensive, dust pollution is serious, and labor costs are high. A medium-sized blisk takes about 3 days ~4 days of grinding time, in addition, the manual grinding and polishing process is affected by the experience of the manual master, and the processing consistency is poor
