Embodiment Construction

[0012] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0013] see figure 1 The friction stir welding seam welding and spot welding integrated spindle of the present invention includes a friction stir welding spindle head having a stirring pin 1 and a stirring sleeve 2 , a driving device and an outer sleeve 3 . The stirring needle 1 is located in the stirring sleeve 2 . The stirring sleeve 2 and the stirring needle 1 are located in the outer sleeve 3 and form a double-moving ring structure together with the outer sleeve 3 . The driving device drives the outer sleeve 3 to rotate around the axis of the stirring needle 1 . The stirring sleeve 2 can move positively and negatively relative to the outer sleeve 3 (assuming that the outer sleeve 3 does not move); the stirring needle 1 can move positi...

Abstract

The invention provides a friction stirring seam welding and spot welding integrated spindle. The spindle is additionally provided with an outer sleeve, and the outer sleeve, a stirring pin and a stirring sleeve form a double-moving-ring structure; the rotational motion of the outer sleeve not only can increase the temperature rise speed of welding materials but also can increase the restraint on plastic flowing materials on the peripheries of the stirring pin and the stirring sleeve. Therefore, the friction stirring welding material backfilling efficiency is increased and the quality of welding joints or welding spots is improved. The requirements of conventional thin wall aluminum lithium alloy seal structures for high quality, high reliability and low stress welding can be met.

Description

technical field [0001] The invention relates to welding equipment, in particular to an integrated spindle for friction stir welding seam welding and spot welding. The spindle integrates two functions of friction stir seam welding and friction stir spot welding. The servo control of the movement of the pumping stirring sleeve can realize the switching between seam welding and spot welding, so as to meet the needs of friction stirring seam welding and spot welding. Background technique [0002] With the development of manufacturing industries such as aerospace, aviation, rail transit, and automobiles, aluminum alloy materials have won favor for their light weight and corrosion resistance, and have been widely used. With the development of industry, the performance of aluminum alloy materials is getting higher and higher, and driven by material technology, the performance of aluminum alloy materials is constantly improving, and a large number of new brands of duralumin, super d...
