2. product clip assembling structure:
The described station that clamps is not to be in the mood for clamping station, and specifically connecting on main shaft 13 upper end has rotating disk 21, rotating disk 21 upper end to set
It is equipped with the support base for supporting workpiece；Main shaft 13, rotating disk 21 and support base are all coaxially disposed.Support base and include circumference
Rule is arranged on some rest pads 22 of rotating disk 21 upper surface, and the cross section of rest pad 22 is L-shaped, in " L " shape of rest pad 22
End face is curved support face, and the curved support face of some rest pads 22 is on same circumference.Said structure forms workpiece clamp
Dress station, in during installation, bearing ring is positioned at Workpiece clamping station, the curved support face of rest pad 22 props up under bearing ring
End face is used for supporting.And in order to reduce the impact that bearing ring is processed by the upper surface flatness error of rest pad 22 further,
Thus described rest pad 22 is made " L " shape, only with curved support face spring bearing lasso, thus reduce and workpiece phase as far as possible
That supports radially contacts with area.Further, since add circumferentially disposed rest pad in man-hour 22 to drive bearing ring by frictional force, especially
It is when starting, produces dynamic friction between rest pad 22 and bearing ring, thus can be split as rest pad 22 supporting seat and resistance to
Abrading block, thus can be easy to the later stage and only change wear-resistant block, cost-effective.
The described station that clamps is provided with for workpiece is positioned at the two groups of supporting positioning components clamping station.Described two groups
Supporting positioning component is for supporting the same peripheral surface of workpiece, and two groups support workpiece and the main shaft 13 that positioning component is supported
Axle center is misaligned.When main shaft 13 drives workpiece to rotate, centripetal force direction suffered by workpiece is pointed between two groups of positioning components.Above-mentioned
What structure was limited be not in the mood for location includes two kinds of situations, when one is that bearing ring inside diameter surface is carried out microstoning, and two groups

Individual upper pressure wheel 25 is separately positioned on the second end of two swing arms 28；The middle part of described swinging axle 27 is located in swing seat
On, swing seat connects and has the driver part for driving swinging axle 27 two ends alternatively swinging.Said structure provides one to swing
The concrete structure of assembly, this structure is in order to realize the function that two upper pressure wheels 25 the most alternately float；Specifically, it is by drive division
Part drives swinging axle 27 two ends alternatively swinging, and swinging axle 27 end drives swing arm 28 so that swing arm 28 with compression axis 26 is
Oscillation center two ends swing, thus realize upper pressure wheel 25 vertical floating on swing arm 28 end.
Above-mentioned compound super lapping machine uses not to be in the mood for clamping, and coordinates the floating of upper surface to compress, can the adding of lift shaft bearing ring
Work precision.Specifically, on the one hand this product clamper uses two groups of supporting positioning components to prop up inside diameter surface or the external diameter table of workpiece
Face so that workpiece is misaligned with main shaft 13 axle center；When main shaft 13 drives workpiece to rotate, workpiece is pointed to two groups by centripetal force direction
Positioning component, so that locating rotation is not in the mood for by workpiece, Workpiece Machining Accuracy is not affected by main shaft 13 running accuracy.The opposing party
Face, this product clamper uses two upper pressure wheels 25 alternately to float workpiece upper surface compression, is axially positioning workpiece
While, it is to avoid the error of workpiece axial end produces impact for Workpiece clamping, thus is further ensured that its machining accuracy.
