Description

Technical Field

[0001] The utility model relates to the technical field of friction welding equipment, in particular to a friction welding equipment. Background Art

[0002] Friction welding uses the heat generated by the friction between thermoplastics or metals to melt the friction surfaces and achieve connection after pressurization and cooling.

[0003] Therefore, friction welding generates heat through friction and does not require an external heat source. When welding cylindrical parts, it is impossible to conveniently clamp and fix the cylindrical parts. Therefore, the Chinese utility model patent disclosed by the existing publication number CN210937644U: a stir friction welding device, the annular seam clamp of the application adopts a single-side drive, and the other side uses a cylinder to push the top. After the weld is tightened, the turntable is driven by the motor + reducer to rotate, and the two sides of the part are synchronously rotated by friction, which simplifies the equipment structure and facilitates the loading and unloading of parts. However, after the two cylindrical parts are clamped and fixed by two chuck structures and moved with the cylinder push, the welding head is in a high-speed rotation state. Therefore, if only one end of the two cylindrical parts with a longer length away from the welding head is fixed in the corresponding chuck, the stirring head will violently scrape and stir the surface of the material during the rotation and forward movement, which will cause the connection end of the two cylindrical parts to be subjected to a large force, resulting in displacement of the cylindrical parts, which is easy to cause the two cylindrical parts to be misaligned at the connection after edge grinding in the later stage.
