AI Technical Summary

Technical Problem

Existing welding and butt clamping devices may cause indentations or elliptical deformation on the surface of steel pipes when clamping them, and excessive clamping force may affect subsequent assembly or use. At the same time, dust on the surface of the steel pipe and its own weight may cause unstable welding.

Method used

The system employs a clamping mechanism, a blowing mechanism, and a supporting mechanism. The clamping mechanism uses components such as rubber pads and limit rods to stably clamp the steel pipe, the blowing mechanism uses air suction to clean away dust, and the supporting mechanism uses sleeves and springs to keep the steel pipe level and prevent deformation and dust from affecting it.

Benefits of technology

It effectively prevents steel pipe deformation during clamping, ensures stable clamping, cleans dust from the surface of the steel pipe, keeps the steel pipe level, avoids sparks during welding, and improves welding quality and safety.

Abstract

The application discloses a welding butt joint device for steel member machining and relates to the technical field of steel welding, which comprises a workbench, a gantry fixedly connected to the top of the workbench, a gas cylinder fixedly connected to the top of the gantry, and a welding head fixedly connected to the output end of the gas cylinder. When the moving motor is started, two sets of clamping plates are driven to move to the position of the steel pipe. When the clamping plates are extruded with the steel pipe and the clamping plates continuously move to the steel pipe, the surface of the steel pipe is pressed or deformed into an ellipse, which affects subsequent assembly or use. When the steel pipe and the clamping plates are mutually attached, the clamping plates are limited to be immovable, and the force for clamping the steel pipe is in a stable state through the cooperation of the rubber pad, the pressing rod, the moving block, the limiting spring, the connecting rod, the limiting rod, the clamping block and the spring. The problem that the clamping plates continuously apply pressure to the steel pipe after clamping the steel pipe, causing the surface of the steel pipe to deform, is solved.
