Abstract

This invention relates to the field of power turret technology and discloses a dual-spindle turning and milling power turret, including a housing and a tool changing unit, a tool drive unit, and a tool disc installed within the housing. An internal displacement tool changing structure is also provided within the housing. The internal displacement tool changing structure includes a movable gear disc, a limiting ring, a rotating gear disc, and a fixed gear disc. By integrating the entire tool changing locking structure into a closed chamber inside the housing, no external operating space is required, significantly shortening the axial length of the entire device and making the overall structure more compact, adapting to the smaller installation space requirements of machining centers. Simultaneously, the entire tool changing clutch process is completed within the closed chamber, completely isolating cutting fluid, metal chips, and dust from the external machining environment, preventing impurities from entering the meshing locking structure and causing tooth surface wear and jamming. This solves the problem of exposed tool changing structures being easily contaminated by impurities and requiring regular cleaning and maintenance, extending the service life of the internal meshing components.
