Large-size cylinder anti-deformation longitudinal joint milling and welding supporting device

Abstract

The invention provides an anti-deformation longitudinal joint milling and welding support device for a large-size cylinder. The anti-deformation longitudinal joint milling and welding support device comprises a headstock and a tailstock, the headstock and the tailstock are fixed at two ends of the base, a support beam is fixed across the tops of the tailstock and the headstock, and the tailstock and the headstock are respectively provided with a left-right centering adjusting mechanism and an up-down leveling wedge block mechanism which are used for adjusting the relative position between the top and the bottom; a detachable clamp beam is installed on the supporting beam. On the basis of an integral external embracing clamp structure, a strong-rigidity pressing function can be realized, and compared with other external embracing modes such as a piano key type, the external embracing clamp is more sufficient in rigidity, simpler to operate and more cost-saving, and the longitudinal seam welding efficiency is improved; arc-shaped control of a barrel product can be achieved, and butt joint and fixation of longitudinal seams are facilitated; the roundness of the barrel can be corrected through a bidirectional left-hand thread telescopic mechanism at the lower end of the auxiliary support, and practicability is high; and milling and welding of products can be achieved respectively, and the welding efficiency is improved.

Description

technical field [0001] The invention relates to a large-size cylinder anti-deformation longitudinal seam milling and welding support device. Background technique [0002] Friction stir welding is a high-efficiency, high-quality, green and environmentally friendly solid-phase welding technology. The deformation of the welded workpiece is small, and it has been widely used in many industries such as aviation and aerospace. The most important thing in the friction stir welding process is to be able to achieve high-strength and rigid internal support and external compression of the workpiece, so the requirements for welding tooling are extremely high, and the strong rigidity of the workpiece can be achieved through welding tooling. At present, the method of cylinder welding is mainly to splice cylinders by circular seam welding. The welding form is limited, and there are specific requirements for the size of the cylinder, which has certain limitations, and the outer clasp mostly...

Problems solved by technology

At present, the welding method of the cylinder is mainly to splice the cylinders by circular seam welding. The welding form is limited, and there are specific requirements for the cylinder size, which has certain limitations, and the external embrace mostly uses piano-key-type pressure jaws. For pressing, the external structure is complicated, the rigidity is insufficient, the operation is extremely inconvenient, time-consuming and labor-intensive
