Problems solved by technology

[0003] The currently used wrist-arm pre-configuration platform simply fixes the wrist-arm tube, manually measures the cutting length of the wrist-arm tube and the size of the installation position of each component on the wrist-arm tube, and visually checks the relative angle of each component. Then install, the degree of automation and pre-configuration accuracy is low, and the qualified rate of finished products is low

Abstract

The invention discloses a catenary cantilever numerical control preassembly platform. The catenary cantilever numerical control pre-equipped platform comprises mutually independent pipe-cutting platforms and a part assembly platform. Each of the pipe-cutting platforms comprises a material discharge end main body, a cutting machine and a material feeding end main body, wherein a first linear guideway is fixed on the material discharge end main body, a first positioning device is mounted on the first linear guideway, and a pipe driving device is mounted on the material feeding end main body. The part assembly platform comprises a main body, wherein an upper linear guideway and a lower linear guideway are fixed on the main body, a second positioning device is mounted on the upper linear guideway, and a rotating device and a fixing device are mounted on the lower linear guideway. The catenary cantilever numerical control preassembly platform has the advantages of improving cantilever preassembly mechanization degree, the processing quality of a cantilever, and the production efficiency of the cantilever.

Description

technical field [0001] The invention relates to the technical field of preparation of railway components, in particular to a numerical control pre-configuration platform of a catenary arm arm. Background technique [0002] Catenary arm pre-configuration is the key process of high-speed railway catenary project construction quality control, and also the primary condition to ensure that the on-site installation and adjustment are in place at one time. The current industry standard "Construction Quality Acceptance Standard for High-Speed ​​Railway Electric Traction Power Supply Engineering" (TB10758-2010) stipulates that "the pre-configuration of the wrist arm is carried out according to the calculation results. The solid moment should meet the design requirements". In the pre-assembly process of the wrist arm, the finished pipe needs to be accurately cut in sections according to the calculated length, and installed according to the installation position of each component on t...
