Quick disassembly tool for assisting in assembly and positioning of tooth-shaped strip and using method

Abstract

The invention discloses a quick disassembly tool for assisting in assembly and positioning of a tooth-shaped strip and a using method. The quick disassembly tool comprises a first clamping block assembly and second clamping block assemblies. The first clamping block assembly is provided with a first matching part, and each second clamping block assembly is provided with a first matching part and a second matching part; the number of the second clamping block assemblies is two or more, and the multiple second clamping block assemblies are arranged adjacently and connected with the second matching parts through the first matching parts; and the first matching part of the first clamping block assembly is connected with the second matching part of one second clamping block assembly, and a long-strip-shaped positioning body is formed by the first matching part of the first clamping block assembly and the second matching part of the second clamping block assembly. The quick disassembly tool for assisting in assembly and positioning of the tooth-shaped strip is reasonable in structural design and convenient to operate, and by means of the using method, the position of the tooth-shaped strip can be adaptively adjusted while the cost and the implementation difficulty are reduced so that the end of the tooth-shaped strip can maintain the good position degree in the follow-up process, and one-time smooth installation of a cross beam is achieved.

Description

technical field [0001] The invention belongs to the technical field of tooling for steam generator tube bundle components, and in particular relates to a quick-disassembly tooling for assisting the assembly and positioning of toothed bars and a use method thereof. Background technique [0002] The direct current steam generator tube bundle assembly of a nuclear power project is composed of multi-layer spiral pipe assemblies, in which the spiral pipe assembly is composed of spiral pipes and toothed bars. Insert the end of the toothed bar, and finally realize the positioning of the spiral tube assembly. [0003] According to the structural characteristics of the product, during the assembly process, the existing technology does not limit the position of the toothed strip on the spiral tube assembly. After each layer of assembly is completed, the crossbeam is used to simulate the tooling from the end of the toothed strip to conform to its position. Check and make adaptive adju...

AI Technical Summary

Problems solved by technology

[0005] 1. After the previous layer of spiral tube assembly is in place, when the next layer of spiral tube assembly is assembled, the tooth bar of the previous layer lacks constraints in the radial direction and will expand outward, which will affect the assembly of the next layer of spiral tube assembly ;

[0006] 2. After the previous layer of spiral tube assembly is in place, when the next layer of spiral tube assembly is assembled, the latter layer of spiral tube will have irregular friction with the previous layer of toothed strips. Because the prior art tooling does not align the toothed strips Limit, the toothed bar will be twisted in the circumferential direction, which will affect the maintenance of the position of the end of the toothed bar, and even affect the supporting effect of the toothed bar on the spiral tube from the design;

[0007] 3. The original technology needs to use simulated tooling to check the compliance after each layer of spiral tube components are installed in place. The inspection cycle is long and the efficiency is low. If the inspection finds a problem, it will be dealt with after the inspection. The cycle is long and the cost is high, and the problem is not fundamentally prevented. the problem occurs;
