The utility model content
The purpose of this utility model is the problems referred to above that exist at prior art, has proposed a kind of built-up jig that need not to remove the mill rocking arm that emery wheel can repair the emery wheel on the grinding machine.
The purpose of this utility model can realize by following technical proposal:
A kind of built-up jig that grinds rocking arm, comprise the clamping device that is fixed on the workbench, this clamping device is used for the clamping rocking arm, it is characterized in that, described built-up jig comprises that also the holder, the level that are fixed on the workbench are arranged in rotating shaft on the holder, can drive the actuator that rotating shaft rotates around himself axis and are shaft-like repair component, the axis of described rotating shaft is perpendicular with the axis of the emery wheel that is used for the above-mentioned rocking arm of grinding, and described repair component can be repaired the machined surface of above-mentioned emery wheel along on the sidewall that radially is fixed on above-mentioned rotating shaft of rotating shaft and its outer end.
In actual use, the built-up jig of this mill rocking arm is arranged on the workbench, and stationary table when it uses, is held on the clamping device place with rocking arm on planker, come the R face on the rocking arm is carried out grinding by the emery wheel that drives grinding machine.In this process, emery wheel rotates around himself rotating shaft, and simultaneously, planker drives rocking arm on workbench and the workbench along moving around so that emery wheel carries out grinding to the R face of rocking arm to perpendicular direction with grinding wheel spindle.When needs are repaired emery wheel, keep the rotation of emery wheel, continue to drag planker and make repair component move to the lower position of emery wheel and control actuator and drive rotating shaft and rotate in order to emery wheel is repaired.Because of the axis of the axis of rotating shaft and emery wheel perpendicular, so when rotating shaft was rotated, the outer end of radially being fixed in the shaft-like repair component on the rotating shaft sidewall was then marked circular-arc track and is come to be equally on the trimming wheel circular-arc machined surface.
In above-mentioned a kind of built-up jig that grinds rocking arm, the center of circle of the arc surface to be processed of the rocking arm after the axis of described rotating shaft and the above-mentioned clamping is on the same straight line.When needing finishing, directly the axis direction moving carriage along rotating shaft can carry out the finishing of emery wheel, need not to adjust planker, dressing accuracy height along other direction.
In above-mentioned a kind of built-up jig that grinds rocking arm, described clamping device comprises support, is horizontally placed on the cylindrical connecting rod one on the support, cylinder one, briquetting and the cylinder two that the energy clamping sleeve is located at the rocking arm on the above-mentioned connecting rod one, described briquetting middle part is hinged with above-mentioned support, the one end is connected with the piston rod outer end of above-mentioned cylinder two, the sidewall of the other end and above-mentioned connecting rod one leans, and this briquetting can press down in the driving of above-mentioned cylinder two and be close to extension bar one.When rocking arm is carried out clamping, several rocking arms are sheathed on the outside of connecting rod one successively, drive cylinder one and compress each rocking arm, drive an end of cylinder two jack-up briquettings, its other end compresses connecting rod one.
In above-mentioned a kind of built-up jig that grinds rocking arm, described support comprises base, vertically is arranged at two root posts and fixed mount on the base, the upper end of described column is provided with V-shaped bayonet socket, the both ends of above-mentioned connecting rod one are arranged at above-mentioned two bayonet socket places respectively, the piston rod outer end of above-mentioned cylinder one is over against the said fixing frame, and described briquetting and fixed mount are hinged.One end of rocking arm need carry out grinding, and cylinder is pressed on the fixed mount so that rocking arm is positioned by the other end of its piston rod with rocking arm first.
As another kind of situation, in above-mentioned a kind of built-up jig that grinds rocking arm, the cylinder three that described clamping device comprises support body, be horizontally placed on the cylindrical connecting rod two on the support body and can clamping sleeve be located at the rocking arm on the connecting rod two, one end and the above-mentioned support body of described connecting rod two are hinged, and the piston rod outer end of described cylinder three is over against the sidewall of above-mentioned connecting rod two.Several rocking arms are sheathed on the connecting rod two, and the piston rod by cylinder three and the sidewall of connecting rod two compress rocking arm can't rotate and play it, because of an end and the support body of connecting rod two hinged, so need not to establish in addition cylinder fixed connecting rod two.
In above-mentioned a kind of built-up jig that grinds rocking arm, described repair component radially is arranged in the above-mentioned rotating shaft along above-mentioned rotating shaft, between described repair component and the rotating shaft by a bolting.Unclamp bolt and can adjust the position of repair component, the fixedly position of repair component tights a bolt.
In above-mentioned a kind of built-up jig that grinds rocking arm, described repair component is diamond pen.Diamond pen is to use comparatively general parts in the present dresser.
In above-mentioned a kind of built-up jig that grinds rocking arm, described actuator is handwheel.Rotate too fastly because the finishing of emery wheel need not repair component, can satisfy the demand of its finishing by the hand rotation handwheel.
In above-mentioned a kind of built-up jig that grinds rocking arm, be provided with transmission mechanism between described actuator and the rotating shaft.Because operating personnel generally stand on the sidepiece of built-up jig, be handled easily, the axis of handwheel and the axis of rotating shaft are perpendicular, so carry out transmission of power by transmission mechanism between the two, here, transmission mechanism can be gear train.
Compared with prior art, when the built-up jig of this mill rocking arm need be repaired at emery wheel, need not to dismantle emery wheel, can be directly along the moving axially built-up jig to diamond pen place and can repair of rotating shaft, easy to operate.Simultaneously, because the center of circle of arc surface on the axis of rotating shaft and the rocking arm is on the same straight line, so the position of adjusting diamond pen makes its outer end get final product to the distance of the shaft axis radius near the rocking arm arc surface, dressing accuracy is higher.
