Abstract

The invention provides an automatic spraying support protection fixture for turbine guide vanes. The automatic spraying support protection fixture is characterized by comprising a base (1), a supporting plate (2), a positioning block (3), a lower baffle (4) and an upper baffle (5). The supporting plate (2) is perpendicularly installed on the base (1), and the top end of the supporting plate (2) is provided with a plane; the positioning block (3) is of a V-shaped plate structure with a forward opening and is used for installing the guide vanes, the bottom surface of the positioning block (3) is installed on the plane of the top end of the supporting plate (2) through bolts, an opening installation surface of the positioning block (3) is matched with installation edges of the vane back sides of lower edge plates of the guide vanes in shape, and the upper edge of the positioning block (3) is flush with the spraying end faces of the lower edge plates of the guide vanes; the lower baffle (4) is of a V-shaped plate structure with a backward opening, an opening part installation surface of the lower baffle (4) is matched with the vane basin sides of the lower edge plates of the guide vanes in shape, and the upper edge of the lower baffle (4) is flush with the spraying end faces of the lower edge plates of the guide vanes.

Description

[0001] Technical field: [0002] The invention belongs to the surface coating protection technology, and relates to the design of the supporting protection tooling required for the automatic spraying of the turbine guide blades of the aero-engine. [0003] Background technique: [0004] As the core component of the engine, the turbine vane assembly of the aero-engine needs to be sprayed with a thermal barrier coating on the surface. Its structure is a double-connected blade, and there is mutual interference and shielding between the front and rear blades and the upper and lower edge plates, and the structure is complex. Restricted by the part structure, the factory has long been painting by hand. However, when spraying manually, the part is placed directly on the operating platform, and the operator rotates or reverses the part after spraying one surface, and then sprays the other surface. Due to the influence of operator experience and subjectivity, process parameters such a...
