AI Technical Summary

Technical Problem

Existing tank welding equipment cannot adapt to tanks of different shapes and sizes, resulting in uneven welded rear faces and deformation of the rolled arc.

Method used

The system employs movable and fixed frames in conjunction with rollers and adaptive clamps. The end faces are made flush by the contact rollers, and multi-linear support is achieved by the angle-rotating brackets and semi-circular adaptive clamps. Combined with the sliding connection of the trapezoidal seat, it ensures precise welding and avoids deformation.

Benefits of technology

It enables precise docking and welding of tank bodies of different sizes, avoiding uneven weld ends and deformation of the rolled arc, thus improving the convenience of welding and the versatility of the equipment.

Abstract

The present application relates to the technical field of vehicle tank body welding, and particularly relates to a vehicle tank body roll-curl post-welding device capable of synchronously pressing a to-be-welded edge, comprising a base, a pressing assembly for self-adaptive correction butt joint of the to-be-welded edge according to the shape of the vehicle tank body arranged on the top of the base, and a welding assembly for adjusting the welding height in linkage with the pressing assembly, the pressing assembly comprising a fixed frame and a movable frame in L-shaped structure, two groups of brackets arranged on the fixed frame and the movable frame, two groups of supporting rollers rotatably connected to the top of the brackets, and a semi-circular self-adaptive clamp arranged above the brackets; the fixed frame is moved to adapt to the fixation of vehicle tank bodies with different lengths, the to-be-welded edge is pressed by the abutting rollers to make the end faces flush, and the tank body with slight oblique roll-curl is corrected; meanwhile, the brackets with angle deflection and the semi-circular self-adaptive clamp can self-adaptively clamp circular or elliptical tank bodies with different sizes, realize accurate butt joint of the to-be-welded edge, prevent deformation of the roll-curl radius, and guarantee the accuracy of the circular arc size after welding.
