Abstract

The invention discloses a single-crystal blade wax pattern combination assembly clamp and a single-crystal blade wax pattern combination assembly method. The single-crystal blade wax pattern combination assembly clamp comprises a base, wherein a rotary chassis, a rotary locking mechanism and a wax pattern fixing mechanism are arranged on the base, the rotary chassis is rotationally connected to the base and used for bearing a wax pattern bottom plate and wax pattern assembly units on the wax pattern bottom plate, the rotary locking mechanism is used for locking the rotation position of the rotary chassis, and the wax pattern fixing mechanism is arranged outside the rotary chassis and used for clamping and fixing the wax pattern assembly units; and the wax pattern bottom plate and the wax pattern assembly units rotate with the rotary chassis along the peripheral direction of the rotary chassis. Each wax pattern assembly unit on the wax pattern bottom plate can be in one-to-one correspondence with a wax pattern assembly unit position, and the wax pattern assembly units are mutually fixedly connected, thus assembly for the whole single-crystal blade wax pattern combination is completed. The single-crystal blade wax pattern combination assembly clamp and the single-crystal blade wax pattern combination assembly method are applicable to investment casting for single-crystal directional blades of various aero-engines and industrial gas turbines.

Description

technical field [0001] The invention relates to the technical field of single-crystal directional blade investment casting of aero-engines and industrial gas turbines, and in particular to a single-crystal blade wax mold assembly fixture. In addition, the invention also relates to a method for assembling single-crystal blade wax models. Background technique [0002] In order to improve the overall performance of aero-engines, the working temperature before the turbines continues to increase, and the ratio of single-crystal blades is getting higher and higher. Compared with equiaxed blades, the crystal growth direction of single crystal blades is strictly limited. It is generally required that the deviation angle θ between the actual single crystal growth direction of the blade and the stacking axis of the blade should not be greater than 10°. The assembly of the single crystal blade wax mold casting system is the first link in the production of single crystal blades. The bl...
