DEVICE FOR MILLING OF RAIL PROFILE Russian patent published in 2012 - IPC B23C3/00 E01B31/13 

FIELD: machine building.

SUBSTANCE: device contains a base, rolling bearings for rail movement, a sensor for fixation of building-up in welded rail joints, profiling mills provided with hard-alloy plates with rotary drives fixed on milling heads, a carriage for mounting of milling heads. Milling heads are arranged considering conditions of treatment of rail full profile in one common carriage with possibility of its movement by drive on base guides along rail axis. Device is provided with rolling bearings installed on carriage for rail fixation and measurements, also it is provided with various measuring transducers. Base is installed by means of travelling wheels on guides in the form of rail-track fixed on foundation and it is capable of movement along rail from initial position to position of rail welded joint. Base contains clamping and damping devices for its fixation against rail-track and gripping dogs for rail fixation in axial direction against base during measuring and milling. Milling head with horizontal arrangement of cylindrical mill axis for machining of lower surface of rail foot is designed to treat side surfaces of rail foot.

EFFECT: improving efficiency and reliability of the device.
