Description
Technical field
The present invention relates to a kind of grinding mechanism of spherical surface body auxiliary section.
Background technology
Often there are some to need the parts of mating spherical surfaces in machinery, it mainly ensures matching somebody with somebody for they by machining accuracy
Precision is closed, because mating spherical surfaces permissible accuracy is often higher, machining accuracy is difficult to ensure that the fit precision of sphere sometimes, and
And the raising of machining accuracy can increase very high production cost.
The content of the invention
It is an object of the invention to for drawbacks described above of the prior art, there is provided a kind of grinder of spherical surface body auxiliary section
Structure, make to be bonded completely between the sphere of mutual cooperation.
For achieving the above object, present invention employs following technical scheme：A kind of grinder of spherical surface body auxiliary section
Structure, the spherical surface body include the first spherical surface body and the second spherical surface body, and first spherical surface body includes the first sphere of indent, described
Second spherical surface body includes the second sphere with the evagination of first mating spherical surfaces, the grinding mechanism bag of the spherical surface body auxiliary section
Objective table and turntable are included, what first, second sphere cooperated is arranged on the objective table, the turntable and rotation
Rotation mechanism is connected and drives first, second spherical surface body to relatively rotate.
In addition, the present invention also proposes following attached technical scheme：
First spherical surface body is fixed on the objective table.
First spherical surface body is provided centrally with rotating shaft and the positioning hole to stagger with the rotating shaft, the objective table include with
Centre bore that the rotating shaft is engaged and the locating dowel being engaged with the positioning hole.
Second spherical surface body is connected with the turntable.
The second spherical surface body center offers mounting hole, and the turntable is provided centrally with being engaged with the mounting hole
Protruding shaft.
The grinding mechanism of the spherical surface body auxiliary section also include set and second spherical surface body and turntable between every
Off member, the separator center offer the avoid holes for avoiding the protruding shaft.
Coefficient of friction between the separator and second spherical surface body is more than rubbing between first, second sphere
Wipe coefficient.
Compared to prior art, the advantage of the invention is that：The grinding mechanism of the spherical surface body auxiliary section of the present invention is by setting
Put objective table and turntable so that rotated against between the sphere of matching, so that reaching complete fitting, nothing between mating surface
High-precision processing, which need to be carried out, to the sphere of mutual cooperation can make both have very high fit precision, simple in construction, save
Cost.
Brief description of the drawings
Fig. 1 is the structural representation of the grinding mechanism of spherical surface body auxiliary section of the present invention.
Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.
As shown in figure 1, corresponding to a kind of grinding mechanism of the spherical surface body auxiliary section of preferred embodiment of the present invention (hereinafter referred to as
Grinding mechanism), mutually grind between the sphere for making mutual cooperation, to reach the purpose being bonded completely.Phase in the present embodiment
The sphere mutually coordinated is the first sphere 1a of indent and the second sphere 2a of evagination, is respectively arranged at the first spherical surface body 1 and second
In spherical surface body 2.
This grinding mechanism includes objective table 3, turntable 4 and separator 5.
First spherical surface body 1 interfixes with objective table 3, does not relatively rotate.It is provided with and is located in the first spherical surface body 1
The rotating shaft 1b of its bottom centre and the positioning hole (not shown) mutually to stagger with rotating shaft 1b positioned at its bottom, on objective table 3
Offer and rotating shaft 1b the centre bore 3a to match and the locating dowel 3b to match with positioning hole.The structure can limit the first ball
The relative position of face body 1 and objective table, prevents from relatively rotating.
The center of second spherical surface body 2 offers mounting hole 2b, and turntable 4 is provided centrally with the protruding shaft coordinated with mounting hole 2b
4a.Separator 5 is arranged between the spherical surface body 2 of turntable 4 and second, and it is provided centrally with the avoid holes 5a for avoiding protruding shaft 4a.It is convex
Axle 4a is stretched into mounting hole 2b through avoid holes 5a, fixes the second spherical surface body 2 and the relative position of turntable 4.Separator 5 uses
The larger material of frictional force, such as rubber, its coefficient of friction between the second spherical surface body 2 should be more than first, second sphere
Coefficient of friction between 1a, 2a, when turntable 4 applies pressure rotary to the second spherical surface body 2, the spherical surface body 2 of turntable 4 and second
Between be advisable with not relatively rotating.The spherical surface body 2 of separator 5 and second can be bolted also by glue adhesion,
During using bolt connection, bolt should not protrude the surface of separator 5, with the surface of the second spheroid of anti-tamper 1.
This grinding mechanism should have higher positional precision, and rotating shaft 1b and mounting hole 2b axis should one after installation
Cause.
In use, objective table 3 is fixed on base 6；First spherical surface body 1 passes through rotating shaft 1b and centre bore 3a, locating dowel
The mating connection of 3b and positioning hole is on objective table 3；Second spherical surface body 2 is placed in the first spherical surface body 1, and both the
First, second sphere 1a, 1b cooperates；Separator 5 is connected on turntable 4, and the Rotatable mechanism such as turntable 4 and motor connects
Connect.Rotating mechanism applies certain extruding force and rotation to turntable 4, so that phase occurs between first, second sphere 1a, 2a
To rotation, mutually grinding, both is bonded completely, reach very high fit precision.
The present invention spherical surface body auxiliary section grinding mechanism by setting objective table and turntable so that the sphere of matching it
Between rotate against so that reach complete fitting between mating surface, without the sphere of mutual cooperation is carried out it is high-precision plus
Work can make both have very high fit precision, simple in construction, save cost.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Allow person skilled in the art to understand present disclosure and implement according to this, the protection of the present invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, it should all be included within the scope of the present invention.
