Integrated friction stir welding equipment

Abstract

The invention discloses integrated friction stir welding equipment which comprises a welding table. A portal frame is arranged on the welding table and comprises a stand column and a cross beam. A first guide rail is transversely fixed to the cross beam. A first driving device is connected with a first sliding table on the first guide rail through a first connecting rod. A first vertical springing device is fixed to the first sliding table. A friction stir welding machine head is connected to the bottom of the vertical springing device. A second guide rail is arranged below the first guide rail in parallel. The tail end of the second guide rail exceeds the tail end of the first guide rail. A second driving device is connected with a second sliding table on the second guide rail through a second connecting rod. A second vertical springing device is fixed to the second sliding table. A fusion welding gun head is connected to the bottom of the second vertical springing device. The integrated friction stir welding equipment can automatically carry out friction stir welding and key hole filling in a controllable mode, and is suitable for being applied in the welding process.

Description

technical field [0001] The invention relates to a friction stir welding equipment, in particular to an integrated friction stir welding equipment. Background technique [0002] Friction stir welding (Friction Stir Welding) is a patented welding technology proposed by The Welding Institute in the United Kingdom. The friction stir welding method is the same as conventional friction welding. Friction stir welding also uses friction heat as a welding heat source. The difference is. The friction stir welding welding process is that a cylindrical welding head (welding pin) is inserted into the joint of the workpiece, and through the high-speed rotation of the welding head, it is rubbed against the material of the welding workpiece, so that the temperature of the material at the joint is increased and softened . At the same time, friction stir is performed on the material to complete the welding. At the end of the friction stir welding, a keyhole will be left at the welding end...

Problems solved by technology

The difference is. The friction stir welding welding process is that a cylindrical welding head (welding pin) is inserted into the joint of the workpiece, and through the high-speed rotation of the welding head, it is rubbed against the material of the welding workpiece, so that the temperature of the material at the joint is increased and softened . At the same time, friction stir is performed on the material to complete the welding. At the end of the friction stir welding, a keyhole will be left at the welding end. Usually, this keyhole can be cut off, or it can be sealed and welded by other welding methods, that is, the friction stir welding is completed. Afterwards, other equipment and methods need to be used to process the keyhole, so it is impossible to realize the automatic processing of the entire welding molding
