Along with the develop rapidly of national economy, national each province has all accelerated the construction of high-speed railway.The track of high-speed railway is made up of gapless rail, and the rail length that steel mill produces is 100 meters one, therefore need become many rail welding the long rail of one in 500-600 rice.Rail adopts high frequency butt welding on welding production line, postwelding will stay the weld seam of the wide about 20mm of high about 2mm, steady and minimizing welding stress and purposes such as location, flaw detection for train operation, and weld seam must reconditioning.At present, artificial hand-held abrasive machine reconditioning is all adopted in the grinding of domestic rail web of the rail part weld seam, and this traditional reconditioning mode efficient is low, and weld seam out-of-flatness after the reconditioning is highly inhomogeneous.According to market survey, along with the high speed development of high speed railway construction, requirement has been satisfied not in artificial grinding.
Summary of the invention
The object of the present invention is to provide the special purpose grinder of a kind of rail in high speed railway weld seam grinding, smooth and identical with surfacing behind this grinding machine with base shape, because the grinding simultaneously of the corresponding bistrique in rail both sides has improved grinding efficiency.
Formation of the present invention: a kind of rail in high speed railway weld seam grinding machine comprises lathe bed, vertically moves planker, infeed planker, clamping device, trimming device, bistrique that lathe bed is installed in the basis of rail
On, vertically move planker and be installed on the V-level gauge of lathe bed, vertically move infeed planker and three groups of bistriques are installed on the planker, respectively web of the rail curve, foot 1:9 inclined-plane and the foot side of grinding rail both sides; Trimming device is installed on the column of 1:9 inclined-plane bistrique, is provided with the golden steel roller shaping trimming wheel with rail web of the rail curve identical appearance, comes the grinding rail weld seam with the formed grinding wheel cylindrical, reaches weld seam curve shape and rail matrix and coincide; The forming grinding wheel grinding is adopted in the foot side, and this emery wheel is through being installed in the emery wheel finishing moulding of both sides; Foot 1:9 inclined-plane adopts the cup emery wheel grinding perpendicular to this inclined-plane.
Above-mentioned rail in high speed railway weld seam grinding machine is provided with totally-enclosed case and dust exhaust apparatus.
Above-mentioned rail in high speed railway weld seam grinder machine both sides are equipped with console.
Above-mentioned rail in high speed railway weld seam grinding machine adopts Siemens 840Dsl digital control system and 1FK7 Series AC servo to control each numerical control axle respectively, to reach the automatic grinding effect.
The rail shift motion of above-mentioned rail in high speed railway weld seam grinding machine is 3 meters.
During use, the present invention is installed on the station behind the rail welding production line, and the lathe bed of grinding machine is installed on two one steel rails of ground; Walk on rail through the motor driven lathe bed, make grinding machine and weld seam contraposition, on two groups of " V-is flat " guide rails on plane on the lathe bed, be separately installed with and vertically move planker; Three bistriques respectively are installed on each planker; Be respectively applied for grinding web of the rail curve, foot 1:9 inclined-plane, foot fillet in parallel shear; The rail head weld seam curve of two track bond postweldings of grinding, both sides web of the rail weld seam curve and foot weld seam curve, and the easement curve between each curve.
The emery wheel of web of the rail curve bistrique and foot side bistrique has a diamond grinding wheel dresser respectively; Crushing one-tenth and rail web of the rail curve; The shape that foot side curve matches adopts the corresponding weld seam of the slow feeding high-rate grinding of forming grinding wheel, because the grinding simultaneously of corresponding two bistriques in rail both sides; The grinding time is short, and efficient improves 4-5 doubly than original artificial grinding.Simultaneously, owing to adopt form grinding technology, the smooth shape basically identical with the rail matrix of the smooth welding joint after the grinding.
Compared with prior art, the surfacing after grinding of the present invention of rail in high speed railway weld seam is smooth and identical with base shape, because the grinding simultaneously of the corresponding bistrique in rail both sides has improved grinding efficiency.
