Abstract

The invention discloses a dual-electric-spindle type spindle handpiece device for friction stir welding. The dual-electric-spindle type spindle handpiece device for friction stir welding mainly comprises a pumpback motor A, a pumpback motor B, a roll screw A, a spline shaft A, a spindle motor stator, a spindle motor rotor, electric spindles, a ball screw B, a spline shaft B, a stirring sleeve, a stirring pin and the like. An electric spindle motor is arranged in the dual-electric-spindle type spindle handpiece device and simultaneously drives the stirring sleeve and the stirring pin to rotate at a high speed. The pumpback motor A and the pumpback motor B can drive the stirring sleeve and the stirring pin to make relative axial motion respectively. The dual-electric-spindle type spindle handpiece device can achieve friction stir spot welding. Meanwhile, the motors are arranged inside a friction stir welding spindle handpiece, the size of the spindle handpiece is reduced, and the flexibility of the spindle handpiece is improved. The dual-electric-spindle type spindle handpiece device for friction stir welding solves the problem that existing friction stir welding spindle handpieces are huge in size and not sufficient in flexibility, and a stirring tool achieving the relative axial motion and spot welding of the stirring pin and the stirring sleeve is gained.

Description

technical field [0001] The invention relates to the field of aerospace equipment manufacturing, in particular to a spindle head device for friction stir welding with double electric spindles, which is suitable for friction stir spot welding machine tools. Background technique [0002] Aluminum alloy materials are favored by many industrial manufacturers due to the advantages of light weight, corrosion resistance, and easy forming. With the continuous improvement of the performance of this material, such as the emergence of new types of duralumin and super duralumin, it is widely used in aerospace, aerospace, Industrial manufacturing fields such as high-speed trains and high-speed ships have been more and more widely used. However, the large welding deformation of the traditional welding method is an important problem that plagues its development. [0003] Backfill friction stir spot welding (FSSW) is a new solid-phase joining technology invented by GKSS Germany on the basis...
