Manufacturing process and tooling of a variable-section truss arm

Abstract

The invention relates to a variable-section truss arm manufacturing process and tools. The process includes the following steps that (1) a main chord member and a connector assembly are formed by means of the tube assembling tool, and (2) by means of the body assembling tool, a variable-section truss arm is formed, wherein the body assembling tool comprises a platform, supporting structures, positioning work tables and body assembling tool connectors, and the installation face of each positioning work table is provided with a connector installation hole set and an installation base connected with the corresponding supporting structure; the step (2) includes the sub-steps that (2-1) the planeness of the platform is adjusted and the platform is fixed, (2-2) the two ends of the platform are respectively provided with one supporting structure, (2-3) the supporting structures are connected with the positioning work tables, and the installation faces of the two positioning work table are opposite, (2-4) the two ends of the main chord member and the two ends of the connector assembly are fixedly connected to the corresponding connector installation hole sets of the positioning work tables through the body assembling tool connectors, (2-5) a web member is welded to the main chord member, and a variable-section truss arm is formed. The variable-section truss arm manufacturing process and the tools are wide in application range, high in manufacturing efficiency and relatively high in safety.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a manufacturing process and tooling for a variable-section truss arm. Background technique [0002] The variable-section truss arm is a truss arm in which the size of each section in the normal direction of the truss arm is different and shows certain regular changes. The manufacturing process of the truss arm usually mainly includes two processes of pipe assembly and body assembly, among which: pipe assembly refers to the process of assembling the main chord of the truss arm and the joints at both ends to form the main chord and joint assembly. Assembly refers to the process of combining the main chord and the joint components into a three-dimensional truss arm. The above-mentioned "joint joint" refers to the process of spot welding parts and components into components or structural parts according to the preset positional relationship. [0003] Such as figure 1 as shown,...

Problems solved by technology

[0005] However, since the variable cross-section truss arms are designed for use under special conditions, there are large differences in the structural forms and sizes of different parts of the variable cross-section truss arms

In terms of the manufacturing process of the variable cross-section truss arm structure, there is no uniformly recognized manufacturing process at home and abroad

Moreover, due to the large size of some variable cross-section truss arms, it is necessary to climb high during the manufacturing process, posing safety hazards
