Abstract

The invention discloses a high-precision mini-type stir-friction welding machine. The high-precision mini-type stir-friction welding machine comprises a welding machine base, a workbench and a fixed frame. The workbench is slidably connected to the upper end surface of the welding machine base, and the fixed frame is vertically and fixedly connected to the upper end surface of the welding machinebase. A vertical-type guide rail is fixedly connected to the end surface, close to the workbench, of the fixed frame, wherein a motor is slidably connected in the vertical-type guide rail, a stir headis connected to the motor through a main shaft box, the stir head is used for carrying out on stir-friction welding of edges of a first workpiece and a second workpiece, and the first workpiece and the second workpiece are fixedly limited in the workbench. The stir-friction welding machine with simple structure has tiny volume, space is saved, the fixed depth of a fixed groove of a workpiece canbe controlled more precisely, and the defects that the fixed depth of the fixed groove of the workpiece cannot be adjusted by a stir-friction welding machine in the prior art according to the thickness of the workpiece to be welded.

Description

Technical field [0001] The invention relates to a friction stir welding machine, in particular to a high-precision miniature friction stir welding machine. Background technique [0002] Friction stir welding is a solid phase joining technology, and its working principle is as follows: In order to ensure that the workpiece to be welded does not move or slip during the welding process, the workpiece to be welded needs to be placed on a rigid backing plate and pressed with a fixture before welding ; The stirring head rotates at high speed and squeezes the stirring needle into the joint of the workpiece to be welded until the shaft shoulder is in close contact with the workpiece to be welded; while the stirring head is rotating at high speed, it moves relative to the workpiece along the adjacent joint, and the stirring is directed to the welded workpiece The stirring of the material and the intense friction between the shafts and the workpiece cause the temperature in the weld nugget...
