Abstract
The utility model discloses a rail bottom grinder used for grinding steel rail bottoms, which is composed of a clamp device, a handrail, a feed mechanism, and a grinding mechanism. The rail bottom grinder has the advantages of simple structure, convenient operation, and high precision, and the steel rail maintaining and grinding quality is ensured.
Description
A kind of flange of rail sander that is used for the polishing of the rail flange of rail.
Rail flange of rail sander is a hand grinding tool plain type sander at present, and it is a work plane with polishing emery wheel circumference, and its polishing precision is low, of poor quality, efficient is low, and labour intensity is big, influences rail maintenance polishing quality, jeopardizes traffic safety.
The utility model provides a kind of precision height of polishing, quality is good, simple in structure, easy to operate, labour intensity is little and efficient is high flange of rail sander.
Flange of rail sander of the present utility model comprises that polishing emery wheel and carriage form, and wherein also is provided with jig, Han Jie feed mechanism with it, and by the workpiece polishing mechanism that junction plate and axis of rotation link to each other with feed mechanism, handrail is sleeved on the motor cabinet.Jig is by support, fixed hook, movable locking plate, positioning screw, handwheel and stop pin holder are formed, feed mechanism is by the feeding seat, lock nut, handwheel, feed screw (being main shaft), bearing, nut, junction plate, axis of rotation and support cover are formed, motor cabinet is sleeved on the axis of rotation, and lock with nut, axis of rotation one end is welded on the junction plate, handrail is sleeved on the motor cabinet, support to be sleeved on the feed screw (being main shaft), support cover one end to be welded on the junction plate, the one end welding of handwheel and feed screw, by handling the position of handrail and adjustment feed screw, realize that abrasive grinding wheel end face and rail foot surface are closely connected.Workpiece polishing mechanism is made up of grinding motor, motor cabinet, emery wheel catcher and abrasive grinding wheel, and the underrun emery wheel catcher of cup-shaped abrasive grinding wheel is connected with grinding motor, and motor cabinet is connected by bolt with grinding motor.
The utility model is through probationary certificate, and it is simple in structure, easy to operate, polishing precision height, and labour intensity is little, has guaranteed rail maintenance polishing quality, raises the efficiency nearly 10 times.
Accompanying drawing is a flange of rail sander structure chart
Among the figure: 1 support, 2 fixed hooks, 3 movable locking plates, 4 positioning screws, 5 handwheels, 6 stop pin holders, 7 handrails, 8 feeding seats, 9 lock nut, 10 handwheels, 11 feed screws (being main shaft), 12,13 bearings, 14 nuts, 15 junction plates, 16 axis of rotation, 17 nuts, 18 grinding motors, 19 motor cabinets, 20 emery wheels catcher, 21 abrasive grinding wheels, 22 rail, 23 support cover.
Fixed hook (2) is welded on respectively on the support (1) with feeding seat (8), positioning screw (4) is sleeved on the removable pin sheet (3), and by being threaded, handwheel (5) welds with an end of positioning screw (4), stop pin holder (6) is inserted in the circular hole of movable locking plate (3), movable locking plate (3) and support (1) hinge joint, handwheel (10) is welded on an end of feed screw (being main shaft) (11), lock nut (9) and feed screw (being main shaft) (11) are by being threaded, supporting cover (23) to be sleeved on feed screw (is on the main shaft (11), support an end and the welding of junction plate (15) one ends of cover (23), support the other end of cover (23) and the other end of feed screw (being main shaft) (11) to lock by nut (14), bearing (12), (13) be contained in the two ends of supporting cover (23) respectively, the other end welding of one end of axis of rotation (16) and junction plate (15), motor cabinet (19) is sleeved on the axis of rotation (16), and by nut (17) locking, handrail (7) is sleeved on the motor cabinet (19), grinding motor (18) is connected by bolt with motor cabinet (19), and abrasive grinding wheel (21) is connected with grinding motor (18) by emery wheel catcher (20).
Its course of work is that jig is stuck on the rail, adjusts the positioning screw position, and locks with the stop pin holder, make the jig positioning and fixing, adjust the position of handrail and feed screw, make the closely connected duty that enters of abrasive grinding wheel end face and rail foot surface, with lock nut fixing after, can polish.
