Description
Technical field
The utility model relates to clamp art, particularly relates to a kind of fixture for Workpiece fixing.
Background technology
Before workpiece is processed on the table, usually need to be located on the table by fixture.Wherein, in workpiece process, prevent workpiece vertically on the table the simplest, that cost the is minimum locate mode of play be: be combined with screw on the table, workbench is provided with the support for screw location, and screw is vertically arranged on above workpiece, the microcephaly of screw and workpiece surface push against to be limited on the table by workpiece.Although the free degree in workplace vertical direction also can be limited in this way, but, after processing multiple workpiece, screw needs repeatedly to dismantle, screw through repeatedly dismantling declines with the intensity that is threaded that the screwed hole on workbench screws, screw easily loosens, namely short by the service life that screw is spacing; In addition, the workpiece of differing heights, needs the support arranging differing heights on the table to locate for screw, and this just substantially reduces the applicable situation of screw location.
Utility model content
The technical problems to be solved in the utility model is, provides the fixture for Workpiece fixing that a kind of long service life, applicable situation are wide.
Technical solution of the present utility model is, there is provided a kind of fixture for Workpiece fixing with following structure: comprise pedestal, pedestal is provided with the workbench for placing workpiece to be machined, also comprise screw, slide block, gear, fork and depression bar, described pedestal is provided with support, support offers screwed hole, and screw screws in the screwed hole on support; Skid is connected on pedestal, and the little head end of screw and slide block end push against or throw off; Pinion rotation is connected on pedestal, and with slide block engaged transmission; Fork one end is relative with gear fixing, and the other end and depression bar one end push against, and the depression bar other end pushes against workpiece surface, on the table hinged in the middle part of depression bar; Described pedestal is provided with the stage clip resetted for slide block, and stage clip one end is connected with pedestal, and the other end is connected with slide block end; Described pedestal is provided with the guide rod for supporting stage clip, and guide rod is slidably connected on pedestal, and compression spring sleeve is connected on guide rod, and guide rod end is provided with the annular protrusion for stage clip location; Described support is slidably connected at pedestal upper surface by dovetail groove, and pedestal is provided with multiple locating hole spacing for support, and support lower surface is provided with blind hole, and locating hole is connected by alignment pin with blind hole, and arranges extension spring between alignment pin and pedestal.
Workpiece is placed on the table by the utility model, adjustment fork is just in time pressed in workpiece surface relative to the relative position of gear face to make the right part of depression bar, again certain driving force is applied to screw, screw rotates and certain axial displacement occurs, namely screw promotion slide block moves and rotates with driven gear, gear driven fork rotates, fork upper end can promote depression bar and rotate clockwise around the pin joint between depression bar and support, namely depression bar right part declines with by Work-sheet pressing on the table, and screw this moment relies on less axial displacement both can workpiece pressing; At releasing depression bar in the process of the compression of workpiece, first fork can be thrown off from gear face to remove fork pushing against depression bar, namely fork is removed to the constraint of depression bar, such depression bar just can be rotated counterclockwise around the pin joint between depression bar and support to remove the constraint of depression bar right part to workpiece surface, is then taken out from workbench by workpiece; Because the stroke before screw is less, so screw just can continue to move ahead in the direction, so next workpiece can be placed on the table, then reorientate to be connected as a single entity relative to the position of gear face to fork, then apply active force to screw, screw promotion slide block moves and is rotated further with driven gear, and gear driven fork is rotated further, fork upper end promotes depression bar and rotates, thus makes the right part of depression bar again be pressed on the upper surface of different workpieces; At releasing depression bar in the process of the compression of workpiece, as abovementioned steps; So move in circles can make full use of screw axis direction stroke repeatedly by different Work-sheet pressings on the table, to improve the service life of screw; And, when needing screw to screw out from support after an axial stroke covered by screw, first remove depression bar to the constraint (namely depression bar and fork upper end are thrown off) of workpiece, extract alignment pin again, slide block reverse slide promote support and slide together under the effect of stage clip, until when slide block and support are not subject to any external drag, screw just can screw out from the screwed hole of support like a cork, and this also can substantially increase the service life of screw; In addition, the fork of a length can meet the compression needs of differing heights workpiece, namely the workpiece of each differing heights specification only needs the angle adjusting fork opposed gear, the workpiece needs of differing heights specification can also be adapted in addition by the length changing fork, then repeat the aforementioned operating procedure to screw applying active force and get final product workpiece pressing, this just substantially increases the applicable situation of this device.Therefore, the utility model fixture for Workpiece fixing of providing a kind of long service life, applicable situation wide.
Preferred as one, described screw axis is parallel with its length direction; Slide block lower surface and pedestal upper surface are slidably connected by dovetail groove, and the axis being parallel of the length direction of dovetail groove and screw.Can the slide block kinetic stability of linearly moving by this preferred design, prevent screw partially sliding in sliding process at promotion slide block.
Preferred as one, described gear and slide block engaged transmission refer to, slide block upper surface is provided with the linear gear rack with gears meshing.Stability and the accuracy of Movement transmit can be ensured by the engaged transmission between gear.
Preferred as one, described fork one end is relative with gear fixedly to be referred to, fork one end and gear hinged; Gear is provided with multiple around equally distributed first through hole of Gear axis, fork is provided with second through hole, first through hole is all greater than zero to distance and second through hole of Gear axis to the distance of Gear axis and equal, and the first through hole is connected by pin with the second through hole.Preferably effectively can be realized by this: fork, relative to the adjustment of angle of gear, makes screw after pushing against slide block, and fork can be thrown off from geared end, then rotate around the pin joint between fork and gear; After putting into next workpiece, again can by the insertion of pin so that gear and fork be reorientated, form one and be different from fork when previous part steps up and, relative to the angle of gear, regulate for screw, and then realize depression bar workpiece pressing again.
Preferred as one, described extension spring one end is fixedly connected with pedestal lower surface, and the other end is fixedly connected with alignment pin lower end.Can realize alignment pin by the connection of extension spring can also automatically reset after the blind hole support is extracted, namely alignment pin is adjacent to pedestal all the time, drops from pedestal to prevent alignment pin.
