The formation of the utility model: a kind of rail in high speed railway weld seam grinding machine; Comprise lathe bed, vertically move planker, infeed planker, clamping device, trimming device, bistrique; Lathe bed is installed on the basis of rail; 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 utility model 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; Adopt 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; 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 the utility model grinding 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.
