Thin-walled tube friction welding anti-pinching supporting piece convenient to adjust

Abstract

The invention discloses a thin-walled tube friction welding anti-pinching supporting piece convenient to adjust, and relates to the technical field of friction welding. The thin-walled tube friction welding anti-pinching supporting piece comprises a base and a fixing clamp mechanism, a first electric push rod is arranged at one end of the top end of the base, and a fixing column is arranged at thetop end of the base in the output end direction of the first electric push rod. The fixing clamp mechanism is located at the end, away from the first electric push rod, of the fixing column, and thefixing column is connected with a limiting sliding rail. By arranging a second motor, a rotating block, a first hinge base, a transmission rod, a second hinge base, a limiting connecting rod, a resetspring and an outer wall clamping block, rapid clamping of the outer wall of a pipeline is achieved, and the rotating block can be driven by the second motor to rotate; and transmission is conducted through a transmission structure composed of the first hinge base, the transmission rod, the second hinge base and the limiting connecting rod so that the outer wall clamping block can conduct contracting and expanding movement, and then the outer wall of the pipeline can be clamped and separated.

Description

technical field [0001] The invention relates to the technical field of friction welding, in particular to a conveniently adjustable thin-walled pipe friction welding anti-pinch support. Background technique [0002] Friction welding is a pressure welding method, using frictional heat as a heat source, heating the two friction surfaces to a plastic state through mechanical frictional movement and applying axial pressure, and connecting the same or dissimilar metals through molecular diffusion and recrystallization at the interface. [0003] The fixtures of the existing friction welding equipment usually use several clamping blocks to cooperate with each other to fix the welded parts. When welding the pipeline, because the thickness of the pipeline wall is very thin, it will be subject to a large clamping force during the clamping and butt welding process. In addition, there is no positioning mechanism when the pipeline is fixed, and it needs to find the location every time th...
