Abstract
The utility model discloses a kind of hold down gag, comprise the pedestal (2) for placing workpiece to be machined (1), workpiece (1) is pressed on pedestal (2) by the first hold down gag, the first described hold down gag comprises first paw (3), a guide rod (4) and a stage clip (5), first paw (3) one end and workpiece (1) upper surface compress, and the other end is fixedly connected with guide rod (4); Guide rod (4) is slidably connected on pedestal (2), and stage clip (5) one end and pedestal (2) lower surface offset, and the other end and guide rod (4) lower end offset; Workpiece (1) is also pressed on pedestal (2) by the second hold down gag be connected with guide rod (4).There is provided a kind of force value large and the hold down gag that continuation is good.
Description
Technical field
The utility model relates to mechanical field, particularly relates to a kind of hold down gag.
Background technology
When work pieces process or workpiece in working order time, when workpiece height changes, workpiece also needs to be subject to one to be continued and constant force value; Such as, in the storage tank of printer dress paper, the carrying out printed along with paper, paper reduces gradually, and namely the height of paper reduces; And in printer to the hold down gag of paper normally a stage clip to prevent a stacker part compact not at vertical direction, specifically, compress paper by the spring force of stage clip to paper exactly.But, along with paper is printed, paper height reduces, thus cause the deflection of spring to reduce, by the known spring of Hooke's law to the spring force of paper also reduction, that is, along with the reduction of paper height, the thrust that paper is subject to is so large under not having original state, and presents the trend reduced gradually.And paper can not be subject to effective thrust and just very easily occurs loose in print procedure, and then cannot print in paper sheet delivery to printing equipment efficiently and accurately.Also relate in field of machining that a lot of workpiece is high to change, and hold down gag also reduces gradually to the thrust of workpiece, after being even worked into, hold down gag is zero for the thrust of workpiece, and this just very easily causes workpiece owing to losing stopping means and play or shake.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of force value large and the hold down gag that continuation is good.
Technical solution of the present utility model is, there is provided a kind of hold down gag with following structure: comprise the pedestal for placing workpiece to be machined, workpiece is pressed on pedestal by the first hold down gag, the first described hold down gag comprises first paw, a guide rod and a stage clip, first paw one end and workpiece surface compress, and the other end is fixedly connected with guide rod; Guide rod is slidably connected on pedestal, and stage clip one end and pedestal lower surface offset, and the other end and lower end of the guide rod offset; Workpiece is also pressed on pedestal by the second hold down gag be connected with guide rod.
The utility model first pulls guide rod to move up and reserves gap on work piece to pedestal, and makes the first paw withhold at workpiece surface, and stage clip is compressed; Along with the decline gradually of workpiece height, lower end of the guide rod is subject to the elastic force effect of stage clip and declines along vertical direction; The second hold down gag work can be driven with the upper surface of workpiece pressing in the process that guide rod declines, make workpiece be subject to two active forces and be pressed on pedestal.Therefore, the utility model provides a kind of force value large and the hold down gag that continuation is good.
Preferred as one, the second described hold down gag comprises a gear and second paw, and described guide rod is provided with linear gear rack; Pinion rotation to be connected on pedestal and with linear gear rack engaged transmission, second paw one end is fixedly connected with gear face, and the other end is pushed against workpiece surface.Decline at the first paw to drive in guide rod vertically decline process, linear gear rack on guide rod can rotate clockwise around its axis by handsetting gear, and the second paw be fixedly connected on gear face also followed by gear around Gear axis and rotates clockwise, namely the right part of the second paw declines with the upper surface being pressed on workpiece.That is, workpiece surface, except by except the thrust of the first paw, is also subject to the thrust effect that continues the second paw compressed.
Preferred as one, described pedestal is provided with the through hole passed for guide rod, and guide rod is slidably connected by dovetail groove and through-hole side wall, and guide rod is vertically arranged.Guide rod is connected with through hole can be provided a direction to the motion of guide rod by the form of dovetail groove, to make guide rod can move along vertical direction, is unlikely to guide rod and sliding inclined phenomenon occurs in motion process.
Preferred as one, described pedestal lower surface is provided with for the spacing blind hole in stage clip end.Can make stage clip that a datum mark can be had after compressive deformation to position by arranging of blind hole, avoid stage clip pressurized and cause the sliding inclined phenomenon in stage clip end to occur.

Shown in figure: 1, workpiece, 2, pedestal, the 3, first paw, 4, guide rod, 5, stage clip, 6, gear, the 7, second paw, 8, linear gear rack, 9, through hole, 10, blind hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model hold down gag comprises the pedestal 2 for placing workpiece to be machined 1, workpiece 1 is on the base 2 compacted by the first hold down gag, the first described hold down gag comprises first paw 3, guide rod 4 and a stage clip 5, first paw 3 one end and workpiece 1 upper surface compress, and the other end is fixedly connected with guide rod 4; Guide rod 4 is slidably connected on the base 2, and stage clip 5 one end and pedestal 2 lower surface offset, and the other end and guide rod 4 lower end offset; Workpiece 1 is also compressed on the base 2 by the second hold down gag be connected with guide rod 4.
The second described hold down gag comprises a gear 6 and second paw 7, and described guide rod 4 is provided with linear gear rack 8; Gear 6 be rotationally connected on the base 2 and with linear gear rack 8 engaged transmission, second paw 7 one end is fixedly connected with gear 6 end face, and the other end is pushed against workpiece 1 upper surface.Gear 6 mentioned here can be rotationally connected by rotating shaft and pedestal 2, and the second paw 7 and the connection of gear 6 can be weld, rivet or other fixed connection.
Described pedestal 2 is provided with the through hole 9 passed for guide rod 4, and guide rod 4 is connected with through hole 9 side walls by dovetail groove, and in other words, guide rod 4 is slidably connected by dovetail groove and through hole 9 inwall; Guide rod 4 is vertically arranged, and namely instructs bar 4 to be vertically arranged in the through hole 9 of pedestal 2.
Described pedestal 2 lower surface is provided with for the spacing blind hole 10 in stage clip 5 end.
The foregoing is only preferred embodiment of the present utility model, not for limiting protection domain of the present utility model.All within the utility model claim, any amendment done, equivalent replacement and improvement etc., all should be included within protection domain of the present utility model.
