AC double-wing-head machine head used for friction stir welding

Abstract

The invention provides an AC double-wing-head machine head used for friction stir welding. The machine head and a lathe bed are connected by installing a slide sleeper and a Z-axis slide carriage through screws, slide blocks and the like. A C axis drive assembly and an A axis drive assembly are each composed of a motor, a speed reducer and the like. The C axis drive assembly and the A axis drive assembly are connected with a C worm and gear assembly and an A axis worm and gear assembly. The C worm and gear assembly and the A axis worm and gear assembly are connected with a C axis assembly and an A axis assembly respectively through screws. The C axis assembly and the A axis assembly pass the C axis drive assembly and the A axis drive assembly and rotate so that a friction stir welding main shaft can rotate in the C axis or the A axis, and the space posture of the friction stir welding main shaft is changed through linkage with all shafts of the lathe bed. Meanwhile, hydraulic locking assemblies are adopted for the A axis and the C axis, it is further ensured that the space posture of the friction stir welding main shaft is positioned and locked on the basis of the worm and gear self-locking function, and therefore a friction stir welding device can be changed at any inclination angle in the three-dimensional space.

Description

technical field [0001] The invention relates to the field of friction stir welding, in particular to an AC double swinging head for friction stir welding. Background technique [0002] Friction Stir Welding (Friction Stir Welding, FSW) is a new type of welding process with outstanding process characteristics such as low stress, small deformation, green, and low energy consumption. It is a solid-phase plastic connection welding process. Friction stir welding can replace the traditional light metal alloy connection technology to meet the requirements of today's products in terms of reliability, efficiency, cost, energy consumption, connection quality, etc., and conform to the current concept of industrial product development. [0003] However, the current conventional friction stir welding technology and equipment have the following problems to be solved: [0004] (1) Traditional friction stir welding equipment is mainly used to complete one-dimensional and two-dimensional fr...

AI Technical Summary

Problems solved by technology

When welding complex workpieces such as three-dimensional space curves and curved surfaces, it is necessary to adjust the welding inclination angle in real time according to the surface of the workpiece, but conventional one-dimensional and two-dimensional friction stir welding equipment cannot meet this demand

[0005] (2) The load capacity of the friction stir welding welding process is relatively large, and the load capacity of the conventional AC swing head is limited

Now the conventional AC swing head is mainly used for material milling, etc., and its load capacity is limited, which greatly limits the application of the AC swing head structure in friction stir welding equipment.
