Method of automatic spraying on guiding blade assembly by double robots

Abstract

The invention provides a method of an automatic spraying on a guiding blade assembly by double robots. The method is characterized by comprising the following steps that regional division is carried out on a spraying procedure of a guiding blade, and the spraying procedure is divided into three parts, namely an upper edge plate, a lower edge plate and blade bodies; the regional division for the upper edge plate and the lower edge plate is carried out, due to the fact that the spraying areas of the upper edge plate and the lower edge plate are the irregular surfaces, and according to the related requirements of the structural characteristics and the design drawing, the spraying areas are divided into five areas such as a crack area between the two blade bodies, in other words, the area is surrounded by the ligature of the top points of the blade basin edge of a rear view left blade body, the blade back air inlet edge of a rear view right blade body and the air inlet edges of the two blade bodies, and the tangent line of the tail end of the blade back air inlet edge of the rear view right blade body, and the blade basin area of the back view right blade body, in other words, the area is surrounded by the extension line of the ligature of the top points of the blade basin edge of the back view right blade body and the air inlet edges of the two blade bodies.

Description

Technical field: [0001] The invention belongs to the surface coating protection technology, and relates to a method for automatic spraying of a guide vane assembly by a double robot. Background technique: [0002] As the core component of the engine, the turbine guide vane assembly of the aero-engine is sprayed with NiCrAlY bonding layer and thermal barrier coating surface layer on its surface. The structure of the guide vane assembly is double-mounted blades, which are divided into upper edge plate, lower edge plate, rear-view left blade body and rear-view right blade body. The shape can be divided into the leaf pot and the leaf back. There is mutual interference and shielding between the left and right leaf bodies and the upper and lower edge plates, and the structure is very complicated. Restricted by the part structure, the factory has been spraying the NiCrAlY bonding layer by hand for a long time. However, manual spraying is affected by the experience and subjective ...

AI Technical Summary

Problems solved by technology

However, manual spraying is affected by the experience and subjective initiative of the operator, and the parameters such as the moving speed of the spray gun and the spraying distance vary, and the quality and consistency of the coating of each blade cannot be guaranteed.
