Description

Technical Field

[0001] This invention relates to the field of friction welding technology, specifically to a friction welding device with automatic positioning function. Background Technology

[0002] Friction stir welding utilizes a special type of stirring head that rotates and advances simultaneously. Heat is generated through friction between the stirring head and the workpiece. This frictional heat puts the metal in a thermoplastic state, and under the pressure of the stirring head, it plastically flows from the front to the rear, thus welding the workpieces together as a single unit.

[0003] Patent application number 201711031657.4 discloses a linear friction welding device. This device includes a column, a vibrating slide, an upsetting slide, an upsetting cylinder, and a balancing cylinder. The vibrating slide can move linearly along the column and is equipped with a vibrating clamp. The upsetting slide is equipped with an upsetting clamp. The upsetting cylinder generates upsetting force and transmits it to the upsetting slide. The balancing cylinder is located between the column and the vibrating slide. The hydraulic oil in the balancing cylinder generates a balancing force that acts on the vibrating slide. This balancing force is opposite in direction to the upsetting force. By generating a balancing force through the hydraulic oil in the balancing cylinder and acting on the vibrating slide, and because this balancing force is opposite in direction to the upsetting force, the deformation caused by the unbalanced force on the vibrating slide can be reduced or even eliminated, thereby improving welding accuracy. This linear friction welding device has a simple and compact structure, is easy to install and disassemble, and can perform friction welding on welding surfaces of different sizes without replacing the welding equipment. It has high welding efficiency and a wide range of applications.

[0004] However, this linear friction welding equipment does not have an automatic positioning function, which requires manual positioning. Such positioning may result in deviations, which can easily cause welding distortion and damage to the workpiece. Therefore, it is necessary to design a friction welding equipment with strong practicality and automatic positioning function. Summary of the Invention
