Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: this float grease seal sealing surface automatic mill in the present embodiment, comprise a workbench 1, the surface of workbench 1 is provided with mill 2, the surface of mill 2 is convexly equipped with pitted skin layer 3, the top of pitted skin layer 3 is provided with a pair roller 4, one of them roller 4 is positioned in the middle part of pitted skin layer 3, another roller 4 is positioned at the edge of pitted skin layer 3, be set in parallel between the rolling surface of roller 4 and pitted skin layer 3, roller 4 is connected with support roller 4 and is hung on support 5 above pitted skin layer 3, support 5 is positioned at the top of pitted skin layer 3, support 5 is connected with pole 6, pole 6 is fixedly connected on workbench 1.
Pitted skin layer 3 is the pitted skin layer 3 adopting burlap to make.
Roller 4 is connected on support 5 by connecting axle 7.
Support 5 has port 8, one end of connecting axle 7 connection bracket 5 is connected in port 8 by bolt 9.
Mill 2 is provided with the containment vessel 10 be looped around outside mill 2, and containment vessel 10 is connected on workbench 1.
Mill 2 is connected with the motor 11 driving mill 2 rotation.
Motor 11 is servomotor.
The technique for grinding of above-mentioned float grease seal sealing surface automatic mill is:
The first step, is first placed on the pitted skin layer 3 of mill 2 down by float grease seal sealing surface to be processed;
Second step, is pushed between a pair roller 4, till float grease seal cannot continue to push again by float grease seal to be processed;
3rd step, opens motor 11 and starts mill 2, and mill 2 starts to rotate;
4th step, evenly spreads on the pitted skin layer 3 of mill 2 by abrasive dust, namely float grease seal carries out sealing surface polishing processing, after polishing completion of processing, takes off the complete float grease seal of polishing from mill 2.
Mill 2 is connected with motor 11, motor adopts servomotor, motor 11 drives mill 2 rotation, float grease seal is placed on mill 2, just friction is there will be between the sealing surface of float grease seal and mill 2, thus carry out the polishing of float grease seal sealing surface, automation can be realized, improve operating efficiency, improve production efficiency, the effect of pitted skin layer 3 is polished to float grease seal sealing surface, and improve the flatness of float grease seal sealing surface, because pitted skin layer 3 is made up of burlap, burlap inherently has polishes to burnishing surface, the effect of polishing, therefore, when float grease seal sealing surface and 3 contact friction of pitted skin layer, the pitted skin layer 3 adopting burlap to make just just is polished to float grease seal sealing surface, polishing, improve the precision of float grease seal sealing surface plane, due on the pitted skin layer 3 that burlap is made, there is certain lines, and more gap between lines, will be formed, when the polishing of float grease seal sealing surface, abrasive dust is layered on pitted skin layer 3, when float grease seal sealing surface and 3 contact friction of pitted skin layer, part abrasive dust plays burnishing action between float grease seal sealing surface and pitted skin layer 3, and the unnecessary abrasive dust of another part will be brought in gap, the abrasive dust of such redundance would not be squeezed between float grease seal sealing surface and pitted skin layer 3, thus decrease the squeezing action that abrasive dust particle diameter produces float grease seal sealing surface, thus prevent float grease seal sealing surface to inwardly concave, improve the flatness of float grease seal sealing surface, improve the sealed precision of float grease seal, roller 4 is for making float grease seal spacing between roller 4, float grease seal is made to there will not be position deviation, ensure that the smooth polishing of float grease seal, support 5 is for installing roller 4, pole 6 is for fixed support 5, ensure that roller 4 can be stabilized in the top of mill 2, connecting axle 7 one end connects roller 4, other end connection bracket 5, one end state in T shape that connecting axle 7 connects roller 4 is arranged, and roller inside is formed with the caulking groove inwardly concaved, this end T-shaped of connecting axle 7 is embedded in caulking groove, time such roller 4 rotates, connecting axle 7 would not rotate, roller 4 can normally be worked, the other end of connecting axle 7 is bolted in the port 8 on support 5, the movement of connecting axle 7 can be realized like this, when needing the float grease seal of polishing arbitrary dimension, mobile link axle 7 just can ensure that the float grease seal of arbitrary dimension is all spacing between roller 4, the float grease seal of arbitrary dimension all can be used, applied widely, containment vessel 10 is fixed on workbench 1, for the protection of mill 2 not by damage, also ensure that operator can not accidentally injure by mill 2, practical application effect is good.
The precision of float grease seal sealing surface plane also refers to the flatness of float grease seal sealing surface.
Adopt the national standard of GB/T11337-2004 flatness Error Measuring, detect the float grease seal sealing surface flatness of the utility model embodiment acquisition and the float grease seal flatness of normal mill polishing acquisition, the result of both contrasts is as following table:
As can be known from the above table, the float grease seal flatness precision that the float grease seal sealing surface flatness adopting the utility model embodiment to obtain obtains than normal mill polishing improves 80%, therefore, the float grease seal sealing surface flatness that the utility model embodiment obtains is that normal mill cannot obtain, precision is high, good seal performance.
The course of work of the utility model embodiment is: be first placed on the pitted skin layer 3 of mill 2 down by float grease seal sealing surface to be processed, and then whole float grease seal is placed between a pair roller 4, then mill 2 is started, mill 2 starts to rotate, then abrasive dust is spread on the pitted skin layer 3 of mill 2, namely float grease seal carries out sealing surface polishing processing, after polishing completion of processing, takes off the complete float grease seal of polishing from mill 2.
The feature of the utility model embodiment is: float grease seal sealing surface can be polished by the pitted skin layer 3 adopting burlap to make, polishing, improve the precision of float grease seal sealing surface plane, the extruding that abrasive dust causes float grease seal sealing surface can also be reduced, prevent float grease seal sealing surface from inwardly concaving, improve the plane precision of float grease seal sealing surface, improve the sealed precision of float grease seal, achieve the automatic processing of float grease seal sealing surface, improve operating efficiency, improve production efficiency, the instructions for use of arbitrary dimension float grease seal can be met, the scope of application is wide, practical application effect is good, be beneficial to popularization.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
