Welding fixture for steel cylinder production and using method thereof

Abstract

The invention relates to a welding fixture for steel cylinder production and a using method thereof. The welding fixture comprises a fixed seat and a movable seat which are opposite front and back, semicircular open grooves are symmetrically formed in the side walls of the opposite sides of the fixed seat and the movable seat, and arc-shaped clamping grooves are formed in the bottoms of the innergrooves of the open grooves. The welding fixture is characterized in that a control clamping assembly used for pushing the movable seat to move relative to the fixed seat to be matched with the fixedseat to clamp a steel cylinder body is arranged on the side, away from the fixed seat, of the movable seat. When the welding fixture is used, the steel cylinder body is clamped into the open grooves formed in the side wall of the fixed seat and clamped into the arc-shaped clamping grooves for further limiting, then the control clamping assembly is arranged on the side, away from the fixed seat, ofthe movable seat, the control clamping assembly pushes the movable seat to move relative to the fixed seat, and therefore the steel cylinder body is fixed after the movable seat and the fixed seat get close to each other and are in extrusion contact. Compared with the prior art that a complex mechanical mechanism is needed for fixing, the welding fixture is simple and reliable in structure.

Description

technical field [0001] The invention relates to the technical field of steel cylinder processing and production, in particular to a welding jig for steel cylinder production and a use method thereof. Background technique [0002] The liquefied gas cylinder is a second-class pressure container for flammable and explosive chemicals. It is widely used in the lives of urban and rural residents and in food stalls, small restaurants and small restaurants in cities and towns. Stability and safety during installation, handling and use. During the welding process, it is usually necessary to use welding fixtures to clamp and fix the steel cylinder body to be welded, and then weld the sides. The current welding fixtures are inconvenient to clamp and use complex mechanical structures to drive and control clamping, and The clamping and fixing of the steel cylinder body is unstable, and it is easy to be disengaged by vibration during the welding process after clamping and fixing, which h...

During the welding process, it is usually necessary to use welding fixtures to clamp and fix the steel cylinder body to be welded, and then weld the sides. The current welding fixtures are inconvenient to clamp and use complex mechanical structures to drive and control clamping, and The clamping and fixing of the steel cylinder body is unstable, and it is easy to be disengaged by vibration during the welding process after clamping and fixing, which has a great impact on the welding quality, so it needs to be improved
