Description
Technical field
The utility model relates to clamp art, particularly relates to a kind of Workpiece clamping device.
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 Workpiece clamping device 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 Workpiece clamping device with following structure: comprise pedestal, pedestal is provided with the workbench for placing workpiece to be machined, also comprise screw, slide block, fork and depression bar, described pedestal is provided with support, support offers screwed hole, and screw screws in screwed hole; Skid is connected on pedestal, and the little head end of screw and slide block end push against or throw off; Fork is rotatably connected on pedestal by the first pin joint, fork lower end and slide block engaged transmission, and upper end is relative with depression bar one end fixing, depression bar other end workpiece pressing upper surface.
Workpiece is placed on the table by the utility model, adjustment depression bar is just in time pressed in workpiece surface relative to the relative position of fork upper end to make the free end of depression bar, again driving force is acted on screw, screw rotates and certain axial displacement occurs, namely screw promotion slide block moves to drive fork to rotate, thus the depression bar of fork upper end is rotated clockwise, namely depression bar free end declines with by Work-sheet pressing on the table, and the axial stroke of screw is this moment less both can workpiece pressing; At releasing depression bar in the process of the compression of workpiece, first depression bar can be thrown off from fork upper end, then workpiece be taken out from workbench; Can also continue to move ahead because the stroke before screw is less, so next workpiece can be placed on the table, then reorientate to be connected as a single entity relative to the position of fork upper end to depression bar, then active force is applied to screw, screw promotes slide block and moves to drive fork to rotate, thus makes the free end workpiece pressing upper surface of depression bar; 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, and in the end screw out in the process of screw, depression bar not press against workpiece, screw can't be subject to any external drag, screw can easily as normal back-out screwed hole exit, and this just substantially increases the service life of screw; In addition, because depression bar free end can have a larger adjustable range at the height of vertical direction, meet the compression needs of differing heights workpiece, namely the workpiece of each height specification only needs to adjust the angle of depression bar relative to fork upper end, 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 Workpiece clamping device 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, the length direction of this dovetail groove and the axis being parallel of 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 fork lower end is engaged with slide block and is referred to, slide block upper surface is provided with linear gear rack, and fork lower end is provided with the arc-shaped rack engaged with linear gear rack; The center of circle of arc-shaped rack is the first pin joint.Stability and the accuracy of Movement transmit can be ensured by the engaged transmission between gear.
Preferred as one, described fork upper end is relative with depression bar one end fixedly to be referred to, depression bar one end is rotationally connected by the second pin joint and fork upper end; Fork upper end is provided with multiple around equally distributed first through hole of the second pin joint, depression bar is provided with second through hole, first through hole is all greater than zero to distance and second through hole of the second pin joint to the distance of the second pin joint and equal, and the first through hole is connected by pin with the second through hole.Preferably can effectively be realized by this: depression bar, relative to the adjustment of fork upper end angle, makes screw after pushing against slide block, depression bar can be thrown off from fork upper end, then rotates around the second pin joint; After putting into next workpiece, again can by the insertion of pin so that depression bar and fork be reorientated, form one and be different from depression bar when previous part steps up and, relative to the angle of fork, regulate for screw, and then realize depression bar workpiece pressing again.
