As depicted in figs. 1 and 2, the embodiment of the present invention provide for rail trimming milling attachment, including milling system,
Alignment system, longitudinal feed system, frame 4 and the traverse feed system being connected with frame 4, milling system includes mill cutter assemblies
11, the milling cutter face of mill cutter assemblies 11 and the upper surface of rail 6, alignment system includes positioning boots 21, the following table of location boots 21
Face and the upper surface of rail 6, longitudinal feed system includes oil cylinder 31 and servo longitudinal feed arrangement 32, servo longitudinal feeding
Device 32 is longitudinally disposed on milling system, and the lower surface of servo longitudinal feed arrangement 32 is connected with the upper surface of location boots 21,
To adjust the lower surface positioning boots 21 pressure to the upper surface of rail 6, oil cylinder 31 is arranged in traverse feed system and and milling
System of cutting connects, with by driving milling system to vertically move, according to the lower surface pressure to the upper surface of rail 6 of location boots 21
Power, adjusts the milling cutter pressure in the face of rail 6 upper surface of mill cutter assemblies 11, thus changes the mill cutter assemblies 11 feed to rail 6
The degree of depth.
The present invention drives longitudinal feed system to move for the milling attachment traverse feed system of rail trimming, thus changes
The lateral attitude of milling system, makes the milling cutter face of mill cutter assemblies be directed at the upper table of rail with the lower surface of the location boots of alignment system
Face, the oil cylinder of longitudinal feed system upwards can bear whole milling system from gravity, milling system one can be given downwards
Individual controlled normal pressure, milling system can rely on its deadweight to move downward under the support of oil cylinder, and this moves downward
Play one by oil cylinder to support and the effect of buffering so that milling system is at the uniform velocity to fall, the activity of servo longitudinal apparatus for feeding
