This invention provides a threaded connection circumferential positioning structure and assembly method, as well as a rotating mechanical component. The structure includes a first housing, a second housing, a positioning key, a locking sleeve, and a looper. The first housing has a shaft section with external threads and a circumferential positioning groove. The second housing is fitted onto the first housing, and its inner wall has multiple circumferentially distributed positioning keyways. By inserting the positioning key, the relative circumferential phase of the two can be selectively fixed. The locking sleeve, as an axial clamping element, is placed in the space enclosed by the stepped surface of the housing, the positioning key, and the end face of the second housing. The looper is fitted over the locking sleeve, and its inner wall has a receiving structure to constrain the locking sleeve. One end of the looper forms an axially limited and circumferentially free floating connection with the second housing, and the other end is threadedly connected to the first housing to fasten the whole. The design transmits the working torque through the key, so that the threaded pair only bears the axial force, preventing vibration and loosening. It achieves accurate, reliable, and adjustable fixing of the circumferential phase, combining low cost and high reliability.

This invention discloses a dual-beam laser additive manufacturing apparatus and method, belonging to the field of additive manufacturing technology. The dual-beam laser additive manufacturing system includes an additive deposition head, a laser shaping module, a drive mechanism, a laser processing head, a substrate support structure, and a machine tool protective cover. The drive mechanism drives the forming substrate to move synchronously through the substrate support structure, achieving relative movement between the substrate and the additive deposition head. This invention's apparatus effectively reduces residual stress in the formed component during manufacturing by synergistically controlling the molten pool solidification process and temperature gradient using dual beams, thereby reducing the tendency for material cracking and significantly improving processing accuracy and forming efficiency. By adjusting process parameters, customized microstructure design can be achieved, thus producing components with specific properties. Through the combination and interactive deposition of different types of beams, this apparatus can adapt to the processing requirements of different materials and working conditions, effectively reducing the difficulty of implementing laser additive manufacturing processes.
