CNC-feed drive for individual tool slide of multi-spindle automatic lathes, uses swiveling screw joints for conveying oil to linkages designed as hydraulic cylinder

摘要

The upper slides/carriages of the tool slides/carriages designed as transverse slides are driven by the piston rods of the angular movable hydraulic cylinder via joints/hinges. The hinges/joints are formed without play on the hydraulic cylinder and the piston rods and the servo-valves for the hydraulic cylinders are arranged outside the working chamber. swiveling screw-joints are provided for conveying the pressure oil to the linkages designed as hydraulic cylinders. The hydraulic cylinders for the upper slide are angularly moveable and are joined over the hinges/joints with the frame components of the multi-spindle automatic lathes. A computerized numeric control (CNC) servo-hydraulic feed drives for individual tool slides/carriages, uses hydraulic cylinders for driving the tool slides and with the linkages for the drive of the tool slide designed as hydraulic cylinders.
