Embodiment

[0017] The structure of the high-altitude cabin of the high-modulus test bench is composed of a head, a cabin body, a hinge assembly, a hatch assembly, and a test platform.

[0018] 1. Assembly and installation of cabin body and rear head:

[0019] The overall shape of the high-modulus test cabin is a cylinder, and its size is φ2000mm×4000mm. There is a test platform in the high-altitude cabin, so when the main parts are welded, the front head is assembled and welded after all the parts are installed, so that The advantages of assembly are 1. It can be more intuitive to measure whether the levelness of the test bench and the ground meets the technical requirements of the test bench; 2. It is convenient to clean the excess parts between the door frame and the cylinder, and make preparations for the installation of other components. good foundation.

[0020] 2. Assemble the reinforcement ring:

[0021] There are 4 sets of reinforcement rings in the test cabin. The reinforcemen...

Abstract

The invention relates to a manufacturing method for a simulation test bed altitude chamber. The method comprises the following steps of assembly installing of a chamber body and a rear sealing head, strengthening ring assembly, assembling and welding of a door frame, test platform fixing, pre-installing adjusting of a hinge assembly, trepanning, welding of a door frame assembly and the chamber body and test platform chamber entry. According to the manufacturing method, accurate trepanning is achieved, and accurate assembling with the door frame is achieved. It is guaranteed that the test platform meets the requirement for the depth of parallelism. The method can be popularized to manufacturing of similar products.

Description

technical field [0001] The invention relates to a method for manufacturing a high-altitude cabin of a simulation test bench, which is mainly used for high-vacuum simulation tests. Background technique [0002] The high-altitude cabin of the engine test platform-high-modulus test bench is mainly used for high-vacuum simulation experiments. Since the test cabin is the main part of the entire test system, after the test cabin is manufactured, there will be auxiliary tests such as heating accessories in the cabin, system electronic controls, and instruments. equipment. Strict implementation of the technical requirements proposed by the design is the prerequisite for the normal operation of the entire test chamber. [0003] However, at present, the manufacture of the high-altitude cabin of the high-modulus test bench has technical problems in the following aspects: 1. The diameter of the cabin is 2000mm, and the door frame is as high as 1100mm, and the door frame is rectangular....
