Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] figure 1 : An embodiment of a rotational friction welding structural assembly formed by axially assembling the joints of the openings of the first workpiece and the second workpiece. The supporting surface 10BT of the first workpiece 10B supports the second workpiece 10C, and the rotary friction welding orifice connecting ring 10A rotates under the pressure of pressing the first welding interface 10H and the second welding interface 11H. As the temperature rises, the second welding interface The material at the first welding interface 10H and the second welding interface 11H is softened and pushed out of the first welding interface 10H and the second welding interface 11H, the rotation is stopped, the workpiece is cooled under pressure, and the friction welding is completed. In addition to flowing into the orifice gap between the first workpiece and the second workp...

Abstract

A spin friction welding structure assembly comprises a spin friction welding orifice connecting ring (20A), a first workpiece (20B) and a second workpiece (20C). The bottom of the spin friction welding orifice connecting ring (20A) is provided with a first friction welding interface (20H) in friction welding connection with the first workpiece (20B) and a second friction welding interface (21H) infriction welding connection with the second workpiece (20C). The first friction welding interface (20H) and the second friction welding interface (21H) of the bottom of the spin friction welding orifice connecting ring (20A) have a step-shaped height difference (TC). A spin friction welding extrudate containing groove (20AC) arranged between the first friction welding interface (20H) and the second friction welding interface (21H) is arranged at the bottom of the spin friction welding orifice connecting ring (20A). The spin friction welding structure assembly can be used for pressure castingof cylinder covers, cylinder cover and cylinder body combined pressure casting parts and orifice high-speed welding of various mechanical devices.
