Description
Technical field
The present invention relates to a kind of axle positioner, especially a kind of hollow axle positioner.
Background technology
At present, in the bearing on textile machine, air-cored axis' class mill processing mode is two top processing, auxiliary during full manual processing
Assistant engineer's dress is more, and action is loaded down with trivial details, and production efficiency is low, and personnel labor intensity is big, because of center hole cause not of uniform size, raceway groove and end face position
Put scattered error big.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of product processing quality is stable, production
The reliable hollow axle positioner of efficiency high, highly versatile and safe operation.
According to the present invention provide technical scheme, the hollow axle positioner, it include main body connecting shaft, mounting seat,
Positioning ball, movable chip and end cap, are fixed with main body connecting shaft in the left side of mounting seat, fix in the right side of mounting seat
There is end cap, cavity is provided with the middle part of the right side of mounting seat, is provided with movable chip in cavity, offer on cavity bottom surface
One circular cone is recessed, and is placed with positioning ball, offers the second circular cone in the left side of movable chip recessed in the first circular cone depression
Fall into, in the embedded second circular cone depression of right hemisphere of positioning ball, have between the bottom surface of the left side wall of movable chip and the cavity
There is flying height, the cylindrical of movable chip has flying height, and main body connecting shaft, mounting seat and the inwall of the cavity between
With the first circular cone depression in being coaxially disposed, movable chip is in be coaxially disposed with the second circular cone depression.
The cone bottom diameter with diameter greater than the first circular cone depression of the positioning ball, the diameter of positioning ball is less than the second circle
The cone bottom diameter of cone depression.
Replaceable wear plate is fixed with the right side wall of movable chip.
The present invention has advantages below：
1st, present configuration is simple, reasonable, easy to use；
2nd, the present invention can arbitrarily select connected mode, highly versatile according to different mill process equipments；
3rd, the present invention is directly positioned using end face, and product processing quality is stable；
4th, production efficiency height of the present invention, low cost, labor intensity is low and safe operation reliability.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the real use state of the present invention with reference to figure.
Specific embodiment
With reference to specific embodiment, the invention will be further described.
The hollow axle positioner, it includes main body connecting shaft 1, mounting seat 2, positioning ball 3, movable chip 4 and end cap
5, main body connecting shaft 1 is fixed with the left side of mounting seat 2, is fixed with end cap 5 in the right side of mounting seat 2, in mounting seat 2
Cavity is provided with the middle part of right side, movable chip 4 is provided with cavity, offers the first circular cone depression 6, the on cavity bottom surface
Positioning ball 3 is placed with one circular cone depression 6, the second circular cone depression 7, positioning ball 3 is offered in the left side of movable chip 4
The embedded second circular cone depression of right hemisphere 7 in, have between the bottom surface of the left side wall of movable chip 4 and the cavity between floating
Gap, the cylindrical of movable chip 4 have flying height, and main body connecting shaft 1, mounting seat 2 and the and the inwall of the cavity between
In being coaxially disposed, movable chip 4 is in be coaxially disposed with the second circular cone depression 7 to one circular cone depression 6.
The cone bottom diameter with diameter greater than the first circular cone depression 6 of the positioning ball 3, the diameter of positioning ball 3 is less than the
The cone bottom diameter of two circular cones depression 7.
Replaceable wear plate 8 is fixed with the right side wall of movable chip 4.
During use, the end face of hollow shaft-like work 9 is close to by the hollow axle positioner of a set of present invention, hollow shaft-like work
9 cylindrical and centering supports 10 and is close to（Be close to while, the center of hollow shaft-like work 9 and positioning ball 3 are in being coaxially disposed）, centering
Supporting 10 can be moved left and right, start machine, and main body connecting shaft 1 is fixed as one motionless with fixed base 12, and workpiece driving motor is opened
Rotated by belt drive one-way clutch bearing 11 after dynamic, hollow shaft-like work 9 passes through the drive of one-way clutch bearing 11 simultaneously
Rotation, emery wheel 13 contacts hollow shaft-like work 9 and is ground, by rotation cause the end face of hollow shaft-like work 9 and movable chip 4 or
Replaceable wear plate 8 on person's activity chip 4 is close to, and main body connecting shaft 1 fixes spacing with mounting seat 2；Positioning ball 3 and activity
Chip 4 slides, as movable chip 4 is floating type installation, natural after rotation to adjust hollow shaft-like work 9 so that hollow axle
Workpiece 9 is in coaxial state with movable chip 4, so as to realize that end face is accurately positioned.
The present invention install can reconditioning or change wear plate 8, the service life of whole device can be extended.
