Abstract

The invention discloses a four-joint guide blade pouring clamp and a processing method. The four-joint guide blade pouring clamp comprises a clamp base used for bottom fixed locating and supporting. The clamp base is provided with a clamping mechanism and a box. The clamping mechanism is used for clamping an upper edge plate and a lower edge plate of a four-joint guide blade part upwards arrangedon the datum plane of a to-be-processed edge plate so as to fixedly locate the four-joint guide blade part. The box is used for supporting and locating the four-joint guide blade part from the bottomof the four-joint guide blade part so as to be matched with the clamping mechanism to clamp the four-joint guide blade part, and is used for being filled with low-melting-point molten alloy temporarily so that relative stability of the located four-joint guide blade part is maintained. The box is assembled on the clamp base. The clamping position of the clamping mechanism on the four-joint guide blade part is located above the pouring face of the low-melting-point molten alloy in the box. Locating is simpler, and precision can be ensured. The four-joint guide blade pouring clamp is suitable for clamping for processing and detection of various complex aero-engine parts.

Description

technical field [0001] The invention relates to the technical field of aero-engine parts processing, in particular to a casting fixture for quadruple guide blades. In addition, the present invention also relates to a method for processing the reference plane of the edge plate of the quadruple guide vane including the casting jig for the quadruple guide vane. Background technique [0002] Quadruple guide vanes for gas turbines (such as figure 1 ), belongs to the quadruple structure, and the blade body is a space surface, with 1#, 2#, 3#, 4# four blade bodies, and the 2#, 3#, 4# blade bodies are obtained by rotating the 1# blade body at a certain angle Come. The blade is composed of an upper edge plate, a lower edge plate and a blade body. The inner curved surface of the upper edge plate is called the outer flow channel, the inner curved surface of the lower edge plate is called the inner flow channel, the surface G shown in the figure is called the opposite end surface of ...
