Abstract: As an important functional component of CNC lathes and turning-milling machining centers, high-speed rotary fixtures play an important role in machining. Because the high-speed rotary clamp has the characteristics of large plate structure and high working speed, huge centrifugal force will be generated during rotation, which leads to the safety problem of unreliable clamping during work. In this paper, the geometric model of the high-speed rotary fixture is established, the contact mode of the key parts of the fixture is defined, and the mechanical properties of the high-speed rotary fixture under the condition of centrifugal force are analyzed by the finite element analysis method; and the different structural sizes, The influence of materials and working speed on the stress and strain of the fixture plate body is studied. Lay the foundation for subsequent fixture structure optimization and failure analysis.
