Abstract
The utility model discloses a kind of pivot pin sanding apparatus, including cradle, grinding wheel, first banking stop, second banking stop, ball and feed table, the cradle is above feed table, and formed with bearing material gap between cradle and feed table, grinding wheel rotates and is located at feed table side, splicing groove is provided with feed table, ball is rotated in splicing groove by the first banking stop and the second banking stop, feed table rotates, when splicing groove on feed table connects with the bearing material gap, pivot pin on cradle is fallen in splicing groove, and grinding wheel side is delivered to by feed table and polished.The utility model automaticity is high, efficiency high, and when grinding wheel polishes pivot pin, pivot pin rotates on ball, the friction that can be effectively prevented between pivot pin and splicing groove, reduces pivot pin surface and is scratched with causing due to friction.
Description
Technical field：
It the utility model is related to a kind of pivot pin sanding apparatus.
Background technology：
When polishing in the prior art pivot pin, generally delivered in sander and polished using manual type, its work
It is low to make efficiency, and safety coefficient is low.Some producers are delivered to pivot pin batch in sander by feed table, but are beaten in grinding wheel
During grinding pivot pin, can also there is friction between pivot pin and feed table, therefore the phenomenon that pivot pin outside wall surface is scratched, meeting occurs
Cause part waste product.
The content of the invention：
The utility model is to provide a kind of pivot pin sanding apparatus to solve the above-mentioned problems of the prior art.
There is technical scheme used by the utility model：A kind of pivot pin sanding apparatus, including cradle, grinding wheel, first
Banking stop, the second banking stop, ball and feed table, the cradle are located above feed table, and between cradle and feed table
Formed with bearing material gap, grinding wheel rotates and is located at feed table side, splicing groove is provided with feed table, ball is spacing by first
Piece and the second banking stop are rotated in splicing groove, and feed table rotates, and the splicing groove on feed table is mutually passed through with the bearing material gap
When logical, the pivot pin on cradle is fallen in splicing groove, and is delivered to grinding wheel side by feed table and polished.
Further, the splicing groove is provided with the stepped hole with First terrace and second step face, and described second
The diameter of step surface is more than the diameter of First terrace, the first banking stop and the second banking stop and is fixed on by the way that screw is corresponding respectively
On First terrace and second step face.
Further, first banking stop is provided with the first positioning hole, and the second positioning hole is provided with the second banking stop,
The aperture of first positioning hole and the aperture of the second positioning hole are respectively less than the diameter of ball, and the aperture of the first positioning hole is less than second and determined
The aperture in position hole.
Further, the splicing groove is provided with 3, is evenly arranged on the outer circle wall of feed table.
The utility model has the advantages that：
The utility model automaticity is high, efficiency high, and when grinding wheel polishes pivot pin, pivot pin rotates on ball, energy
The friction being enough effectively prevented between pivot pin and splicing groove, reduce pivot pin surface and scratched with causing due to friction.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the installation site figure between cradle and feed table in the utility model.
Fig. 3 is the installation site figure between feed table and grinding wheel in the utility model.
Fig. 4 is installation enlarged drawing of the ball on feed table in the utility model.
Embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of pivot pin sanding apparatus of the utility model, including cradle 3, grinding wheel 5, first limit
Bit slice 61, the second banking stop 62, ball 63 and feed table 7, cradle 3 are located at the top of feed table 7, and cradle 3 and feeding
Rotate formed with bearing material gap 70, grinding wheel 5 between the outer circle wall of disk 7 and be located at the side of feed table 7, be provided with feed table 7
Splicing groove 71, ball 63 are rotated in splicing groove 71 by the first banking stop 61 and the second banking stop 62.
For ease of ball 63 is installed in splicing groove 71, being provided with splicing groove 71 has First terrace and second
The stepped hole 72 of terrace, the diameter in second step face are more than the diameter of First terrace, the first banking stop 61 and the second banking stop
62 are fixed on First terrace and second step face by the way that screw is corresponding respectively.
The first positioning hole is provided with the first banking stop 61, the second positioning hole is provided with the second banking stop 62, first is fixed
The position aperture in hole and the aperture of the second positioning hole are respectively less than the diameter of ball 63.The aperture of first positioning hole is less than the second positioning hole
Aperture.Ball 63 is rotatably supported in the stepped hole 72 of splicing groove 71 by the first banking stop 61 and the second banking stop 62,
Grinding wheel 5 polish pivot pin 800 when, pivot pin 800 rotates on ball 63, can be effectively prevented from pivot pin 800 and splicing groove 71 it
Between friction, reduce pivot pin 800 surface and scratched with causing due to friction.
Splicing groove 71 in the utility model is provided with 3, is evenly arranged on the outer circle wall of feed table 7.
When in use, feed table 7 rotates, when the splicing groove 71 on feed table 7 connects with bearing material gap 70, cradle 3
The pivot pin 800 of upper lowermost end is fallen in splicing groove 71, and is delivered to the side of grinding wheel 5 by feed table 7 and polished.This practicality is new
The rotation of feed table 7 in type passes through driving stepper motor, it is ensured that the rotation beat of feed table 7.In the polishing axle of grinding wheel 5
During pin 800, pivot pin 800 rotates on ball 63, the friction that can be effectively prevented between pivot pin 800 and splicing groove 71, reduces
The surface of pivot pin 800 is scratched with causing due to friction.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
The scope of protection of the utility model.
