Problems solved by technology

During the assembly process of this type of compressor rotor, the nuts on the connecting bolts between the disc drums at all levels need to be tightened and the force requirements are limited. However, due to the influence of the rotor structure, the connecting nuts cannot be viewed and touched through the cavity, and conventional The process method and special assembly tools complete the nut tightening and force limiting work

Abstract

An inter-structural-disk connecting force limiting device is used for limiting force and screwing nuts, in an inner cavity of the device, which are less easy to screw. The inter-structural-disk connecting force limiting device is structurally characterized by comprising an operating handle, a matching screwing part (55) and a connecting part, wherein the matching screwing part (55) is used with a screwed nut (2) to be screwed, and the connecting part is used for connecting the operating handle and the matching screwing part (55) and is integrated with the same. The defect that position of the nut and contact with the nut cannot be ensured with human eyes and human hands is overcome, and screwing and force limiting for the nut are achieved. The inter-structural-disk connecting force limiting device is simple and reasonable in design, assembly process of nut screwing is optimized, the technical difficulty in screwing and force limiting for the nut of the special structural disk is overcome, and application of the connecting force limiting device is achieved. In addition, the concept of design can be used for reference and applied to other projects of inter-structural-disk connecting force limiting, and the inter-structural-disk connecting force limiting device is worthy of wide application.

Description

technical field [0001] The invention relates to the structural design and application technical field of structural parts of an assembly auxiliary device for tightening nuts that are inconvenient to be tightened in the inner cavity of equipment, and in particular provides a connection force limiting device between structural plates. Background technique [0002] In the prior art, some equipment inner chambers are provided with special nuts and other assemblies that are inconvenient to be tightened. Typical examples are as follows: The compressor rotor is the core component of the engine, especially the aero-engine, which is characterized by high speed, namely It can reach thousands or tens of thousands of revolutions per minute. Therefore, both the design and the manufacturing and assembly technology of the compressor rotor are very important. There are many basic structural forms of compressor rotors, and there are also different connection methods, and the short bolt conn...
