Description
Technical field
The present invention relates to the technical field of Superfinishing machine, a kind of wabbler mechanism on Superfinishing machine.
Background technology
So-called Superfinishing machine is a kind of machine tool for the surface of parts carries out superhigh precision processing, and it passes through oilstone
Reciprocal grinding on work surface reaches the processing and forming of work surface.This type of Superfinishing machine be mainly used in lasso,
The inside and outside circle processing of the precise parts such as bearing, spherical roller, axle, as a example by bearing inner circle Superfinishing machine of the prior art, its
The course of processing be first by the oilstone of Superfinishing machine against the inner circle of bearing, then drive oilstone edge by the wabbler mechanism on Superfinishing machine
The arc surface reciprocally swinging of bearing inner circle, thus constantly grinding bearings inner circle makes up to required dimensional requirement and surface essence
Degree requirement.But in actual application, this oilstone grinds the process of work surface and actually includes first latter two mistake
Journey, 1) the processing initial stage, oilstone mainly carries out the processing and forming of dimensional profile to bearing inner circle, is used for reaching required size
Required precision, 2) the processing later stage, after the dimensioned completing bearing inner circle, the surface of bearing inner circle is mainly entered by oilstone
Row polishing, is used for reaching required surface finish requirements.The two technical problem to be solved is different, and therefore it is required
Every technical parameter the most just differs.
At the processing initial stage, it is desirable to the mesh number little (i.e. the surface granularity of oilstone is big) of oilstone, amplitude of fluctuation is big, hunting frequency is high
And the rotating speed of workpiece is low big for the pressure of work surface with oilstone, which thereby enhances the grinding capacity of oilstone, makes to be added
Work surface rapid shaping, reaches good dimension precision requirement simultaneously.
After processing the phase then on the contrary, its require that oilstone mesh number is big, amplitude of fluctuation is little, hunting frequency is low, the turning of workpiece
Speed is high and oilstone is little for the pressure of work surface, and bearing inner circle thus can be made to obtain preferable surface accuracy.
But the Superfinishing machine of this prior art, its hunting frequency, workpiece rotational frequency and oilstone are for the force value of work surface
Can be adjusted by controller, but oilstone mesh number cannot be replaced after selected oilstone in the course of processing, meanwhile,
The Superfinishing machine of prior art, the amplitude of fluctuation of its swing mechanism also cannot regulate in the course of processing.Therefore, undue pursuit adds
The dimensioned ability at work initial stage then can cause the surface accuracy of workpiece after molding poor, otherwise, the undue table pursuing the processing later stage
Surface accuracy working ability then can cause the grinding capacity of oilstone poor, causes the consumption for its size molding of same work surface
Duration, more even just and grinds between work surface at processing initial stage oilstone and forms compacted zone, i.e. oilstone surface and workpiece
To be processed upper mutually polishing form the preferable compacted zone of surface accuracy so that oilstone loses dimensioned ability, because of
This, can only carry out compromise to the amplitude of fluctuation of the mesh number of oilstone and wabbler mechanism in prior art and choose, and meets for simultaneously and adds
Work initial stage and the requirement in processing later stage.And this great problem that Superfinishing machine in industry runs in evolution the most just, i.e.
How on the basis of not affecting sizing processes, to reach more preferable surface finish requirements.

6, one end of driving shaft 2 is hinged with one end of connecting rod 6, and the other end of connecting rod 6 and one end of Rocker arm 5 are by universal joint 7
Connecting, the lateral wall of driven shaft 3 is provided with the groove 3.1 that the other end for Rocker arm 5 stretches into, and the other end of Rocker arm 5 is with recessed
The inwall of groove 3.1 is hinged, and driving shaft 2 drives driven shaft 3 along the circumference of own axes toward physical pendulum by Rocker arm 5 and connecting rod 6
Dynamic, the end of described driven shaft 3 is provided with one with the oilstone 8 of driven shaft 3 reciprocally swinging, it is characterised in that: described substrate 1
Be provided with installing plate 9 and for drive installing plate 9 along the elevating mechanism moved axially of driving shaft 2, described driving shaft 2 with
Installing plate 9 is rotatably assorted, and described motor 4 is fixed on installing plate 9.
The operation principle of its driven shaft 3 reciprocally swinging, is that motor 4 is rotated by belt drive driving shaft 2, the thus company of drive
Bar 6 and Rocker arm 5 rotate around the axis position of driving shaft 2, and thus driven shaft 3 is in the reciprocally swinging of certain amplitude of fluctuation.
Certainly described connecting rod 6 add the length of Rocker arm 5 necessarily need more than driving shaft 2 lower end to driven shaft 3 lateral wall it
Between spacing, i.e. need to make Rocker arm 5 and connecting rod 6 inclined.
Described elevating mechanism includes the lifting motor 10 being located on substrate 1, and the outfan of lifting motor 10 is with screw mandrel 11 even
Connecing, installing plate 9 is provided with the leading screw 12 matched with screw mandrel 11.Described elevating mechanism can also use screw rod and screw thread
Coordinate, cylinder can also be used equally to drive installing plate 9 to lift.
Described substrate 1 is provided with one with the installation case 13 of inner chamber, and driven shaft 3 is rotatably assorted in installing case 13, and from
One end of moving axis 3 is placed on outside installation case 13, and described oilstone 8 is located at driven shaft 3 and is placed on the one end installed outside case 13,
Described Rocker arm 5 and connecting rod 6 be placed in install case 13 interior intracavity, one end of described driving shaft 2 penetrate installation case 13 and with
One end of connecting rod 6 is hinged, installs case 13 and is provided with the through hole penetrated for driving shaft 2.
Described substrate 1 is provided with a cover cap 14, cover cap 14 and substrate 1 and surrounds formation one installation cavity, driving shaft 2, lifting
Mechanism and installation case 13 are placed in installation cavity, and one end of described driven shaft 3 passes installation cavity, and described oilstone 8 is installed
On one end that driven shaft 3 is placed on outside installation cavity.

It is noted that being positioned at zone line in the processing cambered surface of oilstone 8 is precision preferable oilstone working area 103, and
Burr or coarse granule, the most referred to as oilstone is often produced with the edge of sidewall junction in the processing cambered surface of oilstone 8
Marginal zone 104.And in the Superfinishing machine of prior art, typically only utilize oilstone working area 103, by working area 103 and work
Grind between the work surface 102 of part 101 and form preferable surface accuracy.In the process, work surface 102 He
A compacted zone 105 all can be formed on oilstone surface.
Its operation principle is, is driven the lifting of installing plate 9 by elevating mechanism, thus makes between driving shaft 2 and driven shaft 3
Spacing produce change, thus the tactical diameter of Rocker arm 5 and connecting rod 6 changes, thus change driven shaft 3 amplitude of fluctuation
Degree.I.e. at the processing initial stage, increase amplitude of fluctuation, so that work surface 102 is constantly ground in oilstone marginal zone 104,
So that the compacted zone 105 on work surface 102 and oilstone surface destroys, improve grinding capacity, and the phase after processing,
Reduce amplitude of fluctuation, thus can make oilstone mid portion polishing work surface, obtain preferable surface accuracy.So,
In the case of amplitude of fluctuation is adjustable, the compacted zone 105 on oilstone surface and work surface 102 can well be abolished, because of
This can select the oilstone that mesh number is bigger, the oilstone of such as 3000-4000 mesh.
