A large-scale split metal core mold assembly tool

Abstract

The invention is a large-scale split-type metal core mold assembly tool, which includes a tool base, a positioning support seat, a left head positioning seat, a positioning column, a support-type pressing and positioning plate, a flange-type pressing and positioning plate, an installation column and a telescopic Support rod; the positioning support seat, the left head positioning seat, the positioning support column and the installation column are respectively installed on the tooling base, and the positioning support seat, the left head positioning seat, the positioning support column and the telescopic support rod are respectively matched with the corresponding profile blocks The positioning of the inner and outer surfaces of the split metal core mold is realized to ensure the accuracy of the external surface of the split metal core mold; the installation column and the positioning groove coaxial with the split metal core mold are arranged in the center of the assembly tooling to ensure the separation of the metal core mold. Concentricity of the body metal mandrel. The invention is suitable for the assembly of large-scale split metal core molds, the tooling base is fixed on the ground, and the integral structure of the split metal core mold is fixed and supported in combination with the positioning support base, thereby ensuring the stability of the assembly tooling.

Description

technical field [0001] The invention belongs to the field of solid rocket motor casing manufacturing, in particular to a large-scale split metal core mold assembly tool. Background technique [0002] The solid rocket motor is the power device of the rocket or missile. The core mold is the mold for winding the rocket motor shell. The geometric shape and size of the inner surface of the shell are guaranteed by the mold. However, each part of the large-scale split metal core mold has high weight and large volume, and the accuracy of the outer surface of the core mold must be ensured during assembly, which brings great difficulties to the assembly of the core mold. [0003] The existing metal core mold assembly tool has poor stability during assembly, cannot effectively fix each split mold of the core mold, and cannot ensure the accuracy of the outer surface after the core mold is assembled, and each split mold is easy to be assembled during assembly. Shaking occurs, affecting ...

Problems solved by technology

However, each part of the large-scale split metal mandrel is heavy and bulky, and the accuracy of the outer surface of the mandrel must be ensured during assembly, which brings great difficulties to the assembly of the mandrel.

[0003] The existing metal mandrel assembly tooling has poor stability during assembly, and cannot effectively fix each split mold of the mandrel, and cannot guarantee the accuracy of the outer surface of the mandrel after assembly. Shaking occurs, affecting the assembly process and resulting in low assembly efficiency
