Abstract

The invention provides a three-dimensional parallel friction stir welding main shaft device. The three-dimensional parallel friction stir welding main shaft device comprises a rack, the rack is cylindrical, a main machine head is fixed at the bottom in the rack, a plurality of groups of parallel mechanisms are mounted on the main machine head, a plurality of lead screw mechanisms are arranged in each group of parallel mechanisms, and the lead screw mechanisms in the plurality of groups of parallel mechanisms are mounted in parallel. Space three-dimensional angle adjustment of the main machine head can be achieved while the main machine head moves up and down, the structural rigidity is sufficient, connection is reliable, and welding of space three-dimensional curve welding seams can be perfectly matched; an independent withdrawing mechanism and a main shaft rotating mechanism are integrated on the main machine head, so that the withdrawing action of a space three-dimensional curve welding seam can be perfectly realized.

Description

technical field [0001] The invention relates to a three-dimensional parallel friction stir welding spindle device. Background technique [0002] Friction stir welding technology is a green, high-quality, high-efficiency, low-distortion and highly intelligent solid-phase joining technology, which is widely used in the welding of aluminum, magnesium and their alloy materials. With the complexity of the size of friction stir welding products and the multi-dimensional appearance, traditional welding equipment can no longer meet the current welding needs, especially the three-dimensional curved welding seam and keyhole welding have become the current technical field of friction stir welding Bottleneck problem to be solved urgently. [0003] Most of the currently disclosed friction stir welding spindle devices are in series structure, and the structural rigidity, bearing capacity and service life are seriously insufficient, and it is difficult to meet the welding requirements of ...
