Automatic-clamping and precise-positioning mechanism of pipeline in flash butt welding

Abstract

The invention discloses an automatic-clamping and precise-positioning mechanism of a pipeline in flash butt welding. The automatic-clamping and precise-positioning mechanism comprises a bottom platform, a traveling mechanism A, a traveling mechanism B, a holding mechanism A, a supporting frame A, a holding mechanism B and a supporting frame B, wherein the traveling mechanism A and the traveling mechanism B are arranged on the bottom platform and consist of two sliding platforms respectively; the holding mechanism A is arranged on one sliding platform of the traveling mechanism A; the supporting frame A is arranged on the other sliding platform of the traveling mechanism A and is connected with the holding mechanism A; the holding mechanism B is arranged on one sliding platform of the traveling mechanism B; the supporting frame B is arranged on the other sliding platform of the traveling mechanism B and is connected with the holding mechanism B; a screw-rod driving mechanism is arranged between the traveling mechanism A and the bottom platform; the supporting frame A is provided with a distance fixing column; the supporting frame B is provided with a longitudinal positioning mechanism. The automatic-clamping and precise-positioning mechanism disclosed by the invention has the advantages that the structure is simple and the operation is convenient; by matching with pipeline flash welding equipment for use, the pipeline can be automatically arranged on the pipeline welding equipment by high efficiency, the positioning accuracy is higher, the difficulty that the installing accuracy cannot be ensured in the manual installation process of the pipeline in flash butt welding is effectively solved, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline flash butt welding automatic feeding equipment, in particular to an automatic clamping precision positioning mechanism for flash butt welding pipelines. Background technique [0002] Flash butt welding is an advanced welding method, the welding process parameters are easy to control and adjust, the process is stable, and the joint quality is good. Compared with the traditional welding method, it has the following advantages: ①It belongs to solid phase welding, there is no molten pool, and the welding quality High; ② No need to add deposited metal, the chemical composition of the welded joint is the same as that of the base metal; ③ No need for gas protection or slag protection, eliminating the source of pollution; ④ High degree of automation, do not rely on manual welding skills. [0003] However, when pipeline flash welding equipment performs pipeline welding, it must first ensure that the pipel...
