Description
The utility model relates to a kind of device of machining bearing.
When bearing is carried out grinding, at first be its cylindrical of grinding, because cylindrical is the location benchmark of interior circle processing, so the relationship between quality of cylindrical circularity is to interior circle, the circularity of axle raceway just, it relates to the key of bearing quality.Bearing top circle grinding at present is to adopt cylindrical to run through grinding machine to carry out basically.This equipment work-piece clamping is no core type, promptly respectively by guide wheel and supporting plate supporting workpiece.Because the difference of workpiece, before processing or in the centre-height that is adding need adjustment in man-hour (overproof as improving workpiece ripple rib) workpiece, it is to realize by the height of adjustment supporting plate support.Be provided with plate supporting frame for this reason on grinding machine wheel frame slide plate, which is provided with supporting plate, the supporting plate that has is to place in the groove, and a side channel wall is provided with screw, with being located at fixedly supporting plate of the interior screw of screw; The supporting plate that also has is to be attached on the attached wall of plate supporting frame, by the bolt that passes attached wall and the vertical through hole of supporting plate both is tightened together.When adjusting the height of workpiece centre, need heavier supporting plate is taken off, change or the increase and decrease supporting plate below cushion block, and then the crack in guide wheel and emery wheel places on the plate supporting frame supporting plate fixing.Its shortcoming is: cushion block quantity is limited eventually, is difficult to find suitable cushion block sometimes; Both having made cushion block a lot, also is the classification adjustment, can not obtain any one height.The transposing of cushion block is the manual labor of loaded down with trivial details heaviness simultaneously, and it has a strong impact on the efficient of cylindrical processing.
The purpose of this utility model is to provide a kind of stepless height-regulating device of centerless grinder that can carry out accurate stepless adjustment quickly and easily to supporting plate support height.
The purpose of this utility model can realize by following measure: the stepless height-regulating device of a kind of centerless grinder, it has a plate supporting frame, it is characterized in that: the skewback that to be provided with two tops in the supporting plate cell body be the inclined-plane, all establish the screw parallel in each skewback with base seat, screw thread in two skewbacks is reverse each other, the end that two leading screws that pass two skewbacks respectively and be meshed with its internal thread are adjacent links to each other by the connecting shaft cover, wherein the other end of a rhizoid thick stick places in the bearing block that is located on the base seat, the other end of another rhizoid thick stick passes another bearing block that is located on the base seat, the end top is fixed with rocking handle, above-mentioned each respectively establish identical both inclined-planes of lower bevel above the skewback and make its end face be the slide block on plane relatively with the skewback gradient, they respectively have two vertical planes to be positioned at the supporting plate cell body vertical guide groove corresponding with it, on side plate of supporting plate cell body, be provided with screw in addition, be provided with trip bolt in it.Be provided with radially screw on the bearing block of a leading screw, being provided with an end and its screw-threaded engagement other end in it is free-ended leading screw set lever.The supporting plate cell body of plate supporting frame is provided with reinforcement outward.
The utility model mainly includes: plate supporting frame, skewback, leading screw, connecting shaft cover, rocking handle, slide block and trip bolt.Wherein plate supporting frame has one flat plate formula base seat, and it can be fixed on the slide plate of grinding machine wheel frame by securing member.Be provided with perpendicular continuous supporting plate cell body on base seat, it and base seat are formed plate supporting frame.This supporting plate cell body can be made up of apart from the parallel-plate that is a bit larger tham the supporting plate width two interblocks, also can be the link to each other cell bodies of formation of two parallel-plate lower ends.Preferably the supporting plate cell body outside is provided with reinforcement.The skewback that to be provided with two tops in the space of supporting plate cell body be the inclined-plane.All establish the screw parallel with base seat in each skewback, the screw thread in two skewbacks is reverse each other.The end that two leading screws that pass above-mentioned two skewbacks respectively and be meshed with its internal thread are adjacent links to each other by connecting shaft.This connecting shaft cover is positioned at the middle part of plate supporting frame, two skewbacks with cross this connecting shaft cover center and with the plane of leading screw axis normal be symmetry.Wherein the other end of a rhizoid thick stick places in the bearing block that is located on the base seat, and the other end of another rhizoid thick stick passes another bearing block that is located on the base seat, and the end top is fixed with rocking handle.Be preferably in this bearing block and be provided with radially screw, be provided with an end and its threaded engagement in it, the other end is free-ended leading screw set lever, and it can be with the leading screw locking positioning.Above-mentioned each respectively to be provided with a lower bevel above the skewback identical with the skewback gradient, both inclined-planes make its end face be the slide block on plane relatively.They respectively have two vertical planes to be positioned at vertical guide groove corresponding with it on the supporting plate cell body.Be provided with screw in addition on side plate of supporting plate cell body, the trip bolt in it can be located supporting plate.
During use supporting plate placed two slide block end faces, with the rocking handle on the hand rotational lead screw, then two skewbacks are respectively to the both direction horizontal slip, and each slide block above the skewback slides up and down along limit guide groove thereupon, so two end faces of vertical slipper can hold up the supporting plate stepless continuous or reduce.After the supporting plate height is determined,, with the screw that passes supporting plate cell body screw supporting plate is located again with leading screw set lever locking leading screw.
The utility model has following advantage compared to existing technology:
1, the utility model can be realized the height of stepless adjustment supporting plate support, not only accurately but also convenient and swift, can satisfy centreless grinding machine external and add the demand of man-hour to the stepless variation of workpiece centre height.
2, the utility model can be eliminated under the situation of circularity over tolerance, makes the product circularity that processes better.
3, the utility model can make the operator break away from heavy manual labor, has improved production efficiency greatly.
