Abstract
The utility model discloses a copper alloy gap steel ball sleeve, including hollow circular cylinder shape copper alloy base member, base member axial both ends opening, the base member inner peripheral surface is equipped with two rectangular shape guide ways, the length direction of two guide ways is parallel with the base member axle center, just two guide ways are with base member axle center symmetry setting, base member axial extension to base member middle part is followed from an open end of base member to a single guide way, the ring channel that is used for installing the snap ring is located still to be equipped with at above -mentioned open end by the base member inner peripheral surface, the ring channel and the coaxial heart of base member, install the snap ring in the ring channel, this snap ring and the coaxial heart of base member, still be equipped with a plurality of mounting holes that are used for installing the steel ball on the base member, every mounting hole all is equipped with a steel ball. The utility model discloses copper alloy gap steel ball sleeve, it can control from the stroke when carrying out axial motion accurately, and it is the problem of unable accurate control stroke at axial motion effectively to solve ordinary steel ball sleeve.
Description
Technical field
This utility model relates to copper alloy gap steel ball sleeve.
Background technology
Steel ball sleeve has in high accuracy axially-movable and radial motion, and fitted shaft and set adopt interference fit, it may be achieved gapless is assembled, and combination precision is high, so being widely used in die industry, and machinery equipment industry, and the industry of running at high precision or motion.
Known steel ball sleeve is mainly made up of matrix+steel ball.Matrix is processed into regular hole according to industry standard, is fitted into by steel ball, and steel ball can flexible motion and difficult drop-off.
Existing steel ball sleeve with supporting axial workpiece with the use of time, it is possible to carry out radial and axial motion, but it cannot control accurately for the stroke of self axially-movable.And have certain requirement, existing steel ball sleeve can not meet this demand on the one hand for the move distance of parts in some mechanical moves.
Utility model content
The purpose of this utility model is in that to provide an Albatra metal gap steel ball sleeve, and it can be accurately controlled from the stroke in time carrying out axially-movable, and effectively solution plain ball is enclosed within axially-movable is the problem that cannot be precisely controlled stroke.
For achieving the above object, the technical solution of the utility model is design one Albatra metal gap steel ball sleeve, including hollow cylindrical copper alloy matrix；
The axial both ends open of described matrix；
Described matrix inner peripheral surface is provided with two strip gathering sills；
The length direction of said two gathering sill and matrix axis parallel；
And said two gathering sill is symmetrical arranged with matrix axle center；
Single gathering sill axially extends in the middle part of matrix from an opening of matrix along matrix；
Described matrix inner peripheral surface is additionally provided with the cannelure for installing snap ring in above-mentioned open end；
The described cannelure heart coaxial with matrix；
In described cannelure, snap ring is installed, this snap ring heart coaxial with matrix；
Described matrix is additionally provided with some installing holes for installing steel ball；
Each installing hole is equipped with a steel ball.
Preferably, described installing hole is uniform on matrix.
Advantage of the present utility model and having the beneficial effects that: provide an Albatra metal gap steel ball sleeve, it can be accurately controlled from the stroke in time carrying out axially-movable, and effectively solving plain ball, to be enclosed within axially-movable is the problem that cannot be precisely controlled stroke.
Steel ball sleeve matrix inwall 180 degree to two gathering sills of side milling (can be corresponding with the salient point in fitted shaft), to keep steel ball sleeve direction when axially-movable to offset.Matrix front inner wall specifies position milling one cannelure, loads onto snap ring, and snap ring can coordinate the movement travel of restriction steel ball sleeve.
This utility model has a characteristic that
1,2 gathering sills of steel ball sleeve matrix inwall, it is ensured that steel ball sleeve is that direction will not offset in axially-movable.
2, the snap ring of steel ball sleeve front end can the stroke of fiting constraint steel ball sleeve.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following example are only for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
The technical scheme that this utility model is embodied as is:
As it is shown in figure 1, an Albatra metal gap steel ball 4 overlaps, including hollow cylindrical copper alloy matrix 1；
The described axial both ends open of matrix 1；
Described matrix 1 inner peripheral surface is provided with two strip gathering sills 2；
The length direction of said two gathering sill 2 and matrix 1 axis parallel；
And said two gathering sill 2 is symmetrical arranged with matrix 1 axle center；
Single gathering sill 2 axially extends in the middle part of matrix 1 from an opening of matrix 1 along matrix 1；
Described matrix 1 inner peripheral surface is additionally provided with the cannelure for installing snap ring 3 in above-mentioned open end；
The described cannelure heart coaxial with matrix 1；
Snap ring 3 is installed, this snap ring 3 heart coaxial with matrix 1 in described cannelure；
Described matrix 1 is additionally provided with some installing holes for installing steel ball 4；
Each installing hole is equipped with a steel ball 4.
Described installing hole is uniform on matrix 1.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
