Description
Technical field
The utility model relates to a kind of axle positioner, especially a kind of hollow shaft positioner.
Background technology
At present, in the bearing on textile machine, air-cored axis class mill processing mode is two top processing, and entirely manually add man-hour auxiliary mould many, action is loaded down with trivial details, and production efficiency is low, and personnel labor intensity is large, causes because center hole is not of uniform size, raceway groove and endface position scattered error large.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides that a kind of product processing quality is stable, production efficiency is high, highly versatile and the reliable hollow shaft positioner of handling safety.
According to the technical scheme that the utility model provides, described hollow shaft positioner, it comprises main body connecting axle, mount pad, positioning ball, movable chip and end cap, main body connecting axle is fixed with in the left side of mount pad, end cap is fixed with in the right side of mount pad, cavity is provided with in the middle part of the right side of mount pad, movable chip is provided with in cavity, cavity bottom surface offers the first circular cone depression, positioning ball is placed with in the first circular cone depression, the second circular cone depression is offered in the left side of movable chip, the right hemisphere of positioning ball embeds in the second circular cone depression, between the left side wall of movable chip and the bottom surface of described cavity, there is flying height, between the cylindrical of movable chip and the inwall of described cavity, there is flying height, and main body connecting axle, it is coaxial setting that mount pad and the first circular cone cave in, it is coaxial setting that movable chip and the second circular cone cave in.
The diameter of described positioning ball is greater than the cone bottom diameter of the first circular cone depression, and the diameter of positioning ball is less than the cone bottom diameter of the second circular cone depression.
Replaceable wear plate is fixed with at the right side wall of movable chip.
The utility model has the following advantages:
1, the utility model is simple and reasonable for structure, easy to use;
2, the utility model can grind process equipment according to difference and select connected mode arbitrarily, highly versatile;
3, the utility model directly uses end face to locate, and product processing quality is stablized;
4, the utility model production efficiency is high, cost is low, labour intensity is low and handling safety is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is real use state reference diagram of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
This hollow shaft positioner, it comprises main body connecting axle 1, mount pad 2, positioning ball 3, movable chip 4 and end cap 5, main body connecting axle 1 is fixed with in the left side of mount pad 2, end cap 5 is fixed with in the right side of mount pad 2, cavity is provided with in the middle part of the right side of mount pad 2, movable chip 4 is provided with in cavity, cavity bottom surface offers the first circular cone depression 6, positioning ball 3 is placed with in the first circular cone depression 6, the second circular cone depression 7 is offered in the left side of movable chip 4, the right hemisphere of positioning ball 3 embeds in the second circular cone depression 7, between the left side wall of movable chip 4 and the bottom surface of described cavity, there is flying height, between the cylindrical of movable chip 4 and the inwall of described cavity, there is flying height, and main body connecting axle 1, mount pad 2 and the first circular cone cave in and 6 to arrange in coaxial, it 7 is coaxial setting that movable chip 4 and the second circular cone cave in.
The diameter of described positioning ball 3 is greater than the cone bottom diameter of the first circular cone depression 6, and the diameter of positioning ball 3 is less than the cone bottom diameter of the second circular cone depression 7.
Replaceable wear plate 8 is fixed with at the right side wall of movable chip 4.
During use, by a set of hollow shaft positioner of the present utility model, the end face of hollow shaft workpiece 9 is close to, the cylindrical of hollow shaft workpiece 9 is close to (while of being close to centering supporting 10, the center of hollow shaft workpiece 9 is arranged in coaxial with positioning ball 3), centering supporting 10 can move left and right, start the machine, main body connecting axle 1 and fixed base 12 are fixed as one motionless, workpiece driving motor is rotated by belt drive one-way clutch bearing 11 after starting, hollow shaft workpiece 9 is by the drive of one-way clutch bearing 11 and rotate, emery wheel 13 contacts hollow shaft workpiece 9 and carries out grinding, by rotating, the replaceable wear plate 8 on the end face of hollow shaft workpiece 9 and movable chip 4 or movable chip 4 is close to, main body connecting axle 1 and mount pad 2 are fixed spacing, positioning ball 3 and movable chip 4 slide, and because movable chip 4 be floating type installation, naturally can adjust hollow shaft workpiece 9 afterwards in rotation, make hollow shaft workpiece 9 be coaxial state with movable chip 4, thus realize end face and accurately locate.
The utility model install can reconditioning or change wear plate 8, the service life of whole device can be extended.
