Bidirectional adjustable cylindrical welding anti-deformation fixture

Abstract

The invention relates to a bidirectional adjustable cylindrical welding anti-deformation fixture which comprises a rotary table, a central compressing component and more than three groups of movable supporting components, wherein the central compressing component is arranged on the rotary table, the rotary table is in a rotation state around the central compressing component, the more than three groups of movable supporting components are uniformly distributed on the rotary table around the central compressing component, and the central compressing component props against the more than three groups of movable supporting components so that the movable supporting components are simultaneously extended outwards or simultaneously retracted. According to the bidirectional adjustable cylindrical welding anti-deformation fixture disclosed by the invention, the central compressing component drives the movable supporting components to prop against and fix a cylinder workpiece, and the rotary table capable of rotating in plane and space drives the cylinder workpiece to rotate in two directions by supporting the movable supporting components so that the cylinder workpiece is located and welded; in addition, the bidirectional adjustable cylindrical welding anti-deformation fixture disclosed by the invention has the advantages of simple structure, convenience in operation, low cost and good welding effect; and the welded workpiece has less possibility of deformation.

Description

technical field

[0001] The invention relates to a welding tool, in particular to a bidirectional adjustable tool suitable for welding cylindrical workpieces and preventing deformation. Background technique

[0002] With the development of wind power generation technology in China, more and more megawatt-level high-power wind turbines are put into operation. In order to ensure that the heat emitted by wind turbines can be cooled in time, cooling equipment for generators is essential, and backpack air-to-air cooling Devices occupy a large proportion of them. Cylindrical workpieces account for a large proportion in backpack air-to-air coolers, and the quality of cylindrical workpieces directly affects product quality. Considering the special environment where the wind turbine is located, the temperature difference in the working environment is large throughout the year. Generally, manual argon arc welding is used, which has poor welding quality stability and low yield....
