A method for automatic spraying of guide vane components by dual robots

Abstract

The invention provides a method for automatic spraying of a guide vane assembly by a double robot, which is characterized in that it comprises the following steps: dividing the spraying program of the guide vane into three parts: an upper edge plate, a lower edge plate and a blade body Part; upper and lower edge plate area division: because the upper and lower edge plate spraying area is an irregular surface, it is divided into five areas according to its structural characteristics and relevant requirements of the design drawing: ①The gap area between the two blade bodies, namely The area surrounded by the blade basin edge of the left blade body in rear view, the blade back inlet edge of the right blade body in rear view, the line connecting the vertices of the two blade body inlet edges and the tangent line at the end of the blade back inlet edge of the right blade body in rear view , ②The basin area of ​​the right leaf body as viewed from the rear, that is, the area surrounded by the extension line connecting the edge of the basin of the right leaf body and the vertices of the air inlet edges of the two blade bodies as viewed from the rear.

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 ...

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.
