Problems solved by technology

[0005] In the field of friction stir welding technology, friction stir welding is currently mostly used for splicing longitudinal seams of cylindrical vessels and a small part for longitudinal seam welding of cylindrical joints. It is not widely used for butt joints of cylindrical joints. Friction stir welding tooling for joint and ring seam welding is not yet perfect
In addition, there is currently a circle supporting mechanism, which can be applied to the inner circle of the cylinder joint or the tooling of the conventio

Embodiment Construction

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0054] Such as figure 1 As shown, the staggered spoke type telescopic tooling for friction stir welding provided by the present invention includes:

[0055]Bearing 110 and bearing sleeve 120, wherein the bearing sleeve 120 is set on the bearing 110, and is used to connect the spoke tooling and the cross manipulator type positioner; during friction stir welding, the position of the welding head remains unchanged, and the barrel section follows the positioner Rotate, at this time, the spoke tooling rotates with the barrel joint, and the bearing is fixed on the cross manipulator type positioner.

[0056] The first support ring 130 is located outside the bearing sleeve, the inner ring of the first bearing ring 130 is connected to the bearing sleeve 120, and can rotate with the b...

Abstract

The invention discloses a staggered spoke type stretchable tool for friction stir welding. The staggered spoke type stretchable tool comprises a bearing, a bearing sleeve, a first supporting ring, a second supporting ring, a third supporting ring and a plurality of supporting plates, the bearing is used for connecting the spoke type tool with a cross-shaped operation machine type dislodgement machine, the bearing sleeve is rotationally arranged on the bearing in a sleeving manner, the first supporting ring is annular, an inner ring fixing sleeve is arranged on the bearing sleeve and can rotatealong with the bearing sleeve, the multiple first air cylinder assemblies are arranged on the outer ring of the first supporting ring and distributed on the outer side of the first supporting ring ina circumferential array equal-interval manner, the second supporting ring is annular, is concentric with the first supporting ring and is arranged on the outer side of the first supporting ring, a plurality of round holes are formed in the second supporting ring, air cylinders can penetrate the round holes, the supporting plates are arc-shaped plates, and the first air cylinder assemblies can bedetached to be far away from one end of the third supporting ring. The invention further discloses an adjusting method of the staggered spoke type stretchable tool for friction stir welding.

Description

technical field [0001] The present invention relates to a welding tool, in particular to a staggered spoke type telescopic tool for friction stir welding and an adjustment method thereof. Background technique [0002] Natural gas and petroleum, coal and their processed products are interchangeable in many application fields, mainly used in urban residential gas, transportation, power generation, and chemical industries. As an important logistics equipment, tank trucks are widely used in the automobile transportation industry. Friction stir welding (FSW) is a new solid-state welding method that has recently emerged. Since its appearance, it has been rapidly developed and promoted. In practical engineering applications, friction stir welding has outstanding process advantages such as large single-pass welding thickness, low defect occurrence rate, small welding residual stress and deformation, high welding efficiency, energy saving and consumption reduction, and green weldin...
