Above；Molding polishing stone face is designed to rail lip position target polishing profile, passes through feed system and positioning
System is realized laterally with vertical accurate positioning, and the polishing of rail lip is realized under the driving of dynamical system.
Further, when one side, steel rail grinding is finished, the sander exchanges direction, and walking, which is rotated to, has polished
On the rail of one side, the molding polishing grinding wheel continues to polish to the another side rail that do not polish.
Further, the dynamical system includes power source and shaft coupling, and the line shaft of power source is connected with shaft coupling
It connects.
Further, the power source is motor, hydraulic motor or internal combustion engine.
Further, the feed system includes that feed screw nut pays and control hand handle.
Further, the positioning system includes interior survey locating wheel, bracket and spring.
Further, the molding polishing grinding wheel is made of matrix and working lining, and described matrix can use metal, powder metallurgy
Or non-metallic material is process, working lining is made of abrasive material, bonding agent；It can add between described matrix and the working lining
Enter transition zone, the transition zone is part working lining being securely attached to by binding material on matrix.
Further, the molding polishing grinding wheel rotary shaft installation site is horizontal position or upright position；The molding
Polishing grinding wheel is provided with mounting hole, is provided with chip pocket in buffed surface.
The beneficial effects of the utility model are:
A kind of rail fat-edges sander and its grinding wheel provided by the utility model, the fat edges sander can be used big cutting-in and beat
Grinding process is designed to that rail lip position target is beaten by primary or the rail lip of polishing removal for several times, polishing stone face
Profile is ground, has the advantages that high in machining efficiency, machining accuracy is high, surface integrity is good, which has polished behind rail one side
It can be switched polishing another side rail, it is easy to use.Polishing stone face is equipped with chip pocket, convenient for the exclusion of polishing bits and heat
It sheds, steel rail grinding overheat is avoided to turn blue.
