Meet to repair and require, avoid reciprocating operation, have the advantages that operating efficiency is high, precision is high, effect is good, limitation is few, and
Coordinate the automatic filing collector of milling car in operation process so that repair process ensures clean environment, rail physical dimension after operation
All improved a lot with Rail Surface flatness, finish, the stationarity and security of train operation can not only be lifted, moreover it is possible to
Wheel track noise is enough reduced, lifts the comfort level of passenger.
The purpose of the present invention is achieved through the following technical solutions：Rail repairs profile milling cutter online, it is characterised in that：Institute
Stating milling cutter includes cutter hub, blade, blade screw-in compression and tool rest, and the blade includes circular arc blade and straight sword blade, the knife
The circumference of body is provided with multiple radial positioning faces, axial locating surface, and the cutter hub is additionally provided with the cutter hub key with positioning function
Groove, the tool rest include side tool seat and upper cutter head, and the side tool seat and upper cutter head are in radial positioning face, axial locating surface and knife
It is anchored under the limitation of body keyway by screw group on cutter hub, the circular arc blade and straight sword blade pass through blade screw-in compression
Corresponding to being anchored in insert groove, multiple rows of blade mutually overlaps to form complete forming surface cutting edge.
The screw group includes tool rest housing screw, tool rest baroclines screw and tool rest oblique pull screw.
The side tool seat keyway of one indent is arranged at the side tool seat bottom, and side tool seat keyway is arranged on key so that side tool seat
Positioning end face be close to axial locating surface, radial positioning face is close in the positioning bottom surface of side tool seat, and side tool seat compresses spiral shell by tool rest
Nail, the tool rest screw that baroclines are fixed on cutter hub.
The key of one protrusion is arranged at the upper cutter head bottom on cutter hub, and tool rest convex key is arranged in cutter hub keyway,
Axial locating surface is close in the positioning end face of upper cutter head, and radial positioning face is close in the positioning bottom surface of upper cutter head, and the upper cutter head passes through
Tool rest oblique pull screw is fixed on cutter hub.
The tool rest, which baroclines between screw and the positioning bottom surface of side tool seat, has a ° of angle.
A ° of angle, while tool rest oblique pull screw and knife be present between fixed position bottom surface in the tool rest oblique pull screw and upper cutter head
B ° of angle between body keyway be present.
It can be seen from the above description that the present invention has advantages below：Multiple rows of blade on tool rest is mutual
Overlap joint, form complete rail operable profile face cutting edge, so can by disposably by Milling Process in a manner of process institute
Need type face.The robust structure of tool rest and cutter hub make it that tool rest is not easy to rock or dropped milling cutter in rigid milling, and rail repairs matter
Amount is more stable, and the molded line uniformity of rail surface is high.Compared to original polishing operation mode, after the milling operation, rail geometry
Size and Rail Surface flatness, finish all improve a lot, and also greatly reduce the workload for repairing rail.
