Abstract
The utility model discloses a rail end flat grinding machine used for grinding steel rail ends, which is composed of a clamp apparatus part, a feed mechanism, and a grinding mechanism. The rail end flat grinding machine has the advantages of simple structure, small size, convenient operation, high precision, and the ensuring of steel rail weld quality.
Description
A kind of rail that is used for the steel rail end polishing is held grinding machine level with both hands.
Steel rail end polishing at present is hand grinding tool plain type flat-grinding machine, and it is a working face with the emery wheel circumference, and its low precision of polishing is of poor quality, and labour intensity is big, has influenced the rail welding quality, jeopardizes traffic safety.
The utility model provide a kind of simple in structure, volume is little, easy and simple to handle, polishing precision height, can raise the efficiency, and guarantees that the rail of rail welding quality is held grinding machine level with both hands.
The utility model is made up of jig part, feed mechanism and workpiece polishing mechanism.Jig partly is made up of jig, jig tie down screw and handwheel, the jig tie down screw is sleeved on the jig, and by being threaded, jig is stuck on the rail tread, adjust the position of jig tie down screw, jig is fixed on the rail, owing to adopted a jig tie down screw to make the jig accurate positioning.Feed mechanism is made up of rotating spindle, feed nut, retaining sheet, locking mother and top cap, rotating spindle is sleeved in the motor cover for seat, its stiff end is connected on the jig with bolt, feed nut is sleeved on the supply side of rotating spindle, one end of motor cover for seat is embedded on the feed nut, adjust feed nut, can make motor cabinet be enclosed within axial displacement, after feed nut is fixing, the motor cover for seat can radially rotate freely, thereby realized that abrasive grinding wheel working face and rail end face convex portion are closely connected, polished.Workpiece polishing mechanism is made up of grinding motor, motor cabinet, motor cover for seat, emery wheel catcher and abrasive grinding wheel, and the emery wheel that the bottom surface of cup-shaped abrasive grinding wheel is fixed on the electric machine main shaft is taken over, and the end face of abrasive grinding wheel is a working face.
The utility model is at the track division probationary certificate, and it is simple in structure, volume is little, easy and simple to handle, polishing precision height, has guaranteed the rail welding quality, raises the efficiency 10 times.
The utility model has following accompanying drawing
Fig. 1 rail is held mill structure figure level with both hands
Fig. 2 rail is held mill structure figure level with both hands
Among the figure: 1 jig, 2 jig tie down screws, 3 handwheels, 4 rotating spindles, 5 feed nuts, 6 retaining sheets, 7 lockings are female, 8 top caps, 9 grinding motors, 10 motor cabinets, 11 motor cover for seat, 12 emery wheels catcher, 13 abrasive grinding wheels, 14 motor switch, 15 rail.
Jig tie down screw (2) is sleeved on the jig (1) of casting, with being threaded, handle (3) is welded on an end top of jig tie down screw (2), jig (1) is connected the stiff end of rotating spindle (4) with bolt, motor cover for seat (11) is sleeved on the rotating spindle (4), feed nut (5), retaining sheet (6) and locking nut (7) are sleeved on the supply side of rotating spindle (4), top cap (8) is installed on the supply side top of rotating spindle (4), one end of motor cover for seat (11) is embedded on the feed nut (5), motor cabinet (10) is cast one altogether with motor cover for seat (11), grinding motor (9) is connected on the motor cabinet (10) with bolt, emery wheel catcher (12) is sleeved on the main shaft of grinding motor (9), the bottom of cup wheel (13) is contained on the emery wheel catcher (12), and fixes by nut.
Its course of work is that jig (1) is stuck on the rail (15), adjusts the position of jig tie down screw (2), makes the jig positioning and fixing, adjust feed nut (5), make the convex portion of the working face of abrasive grinding wheel (13) and rail end face closely connected, with locking female (7) fixing after, can polish.
