| Zusammenfassung: | The invention discloses a two-degree-of-freedom power vibration absorption boring bar. The two-degree-of-freedom power vibration absorption boring bar comprises a tool bit, a composite structure tool bar, a two-degree-of-freedom power vibration absorber and an adjusting stud. The composite structure tool bar comprises a metal sleeve and a carbon fiber rod which is bonded to the rear end of the inside of the metal sleeve. The adjusting stud is connected to the front end of the inside of the metal sleeve in a threaded mode. The two-degree-of-freedom power vibration absorber is arranged between the adjusting stud and the carbon fiber rod inside the metal sleeve. The vibration absorber is mainly composed of two sets of mass blocks and damping springs to form a two-stage vibration absorption system, and two annular gaps capable of containing damping fluid are formed in the two-stage vibration absorption system. When the tool bar vibrates, the two-degree-of-freedom power vibration absorber can vibrate accordingly, |
