Description
Technical field
The utility model relates to mechanical field, particularly relates to a kind of compressing fixture.
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 compression apparatus 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 compression apparatus also reduces gradually to the thrust of workpiece, after being even worked into, compression apparatus 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 compressing fixture that continuation is good.
Technical solution of the present utility model is, there is provided a kind of compressing fixture 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 first stage clip, first paw one end and workpiece surface push against, and the other end is fixedly connected with guide rod; Guide rod is slidably connected on pedestal, and first stage clip one end is connected with pedestal lower surface, and the other end is connected with the external part of guide rod, and pedestal is provided with the connecting rod interted in the first stage clip, and small end and pedestal screw, and connecting rod lower end is through the external part of guide rod; Workpiece is also pressed on pedestal by the second hold down gag be connected with guide rod, and the second described hold down gag comprises a gear and second paw, and described guide rod is provided with linear gear rack; Gear to be connected on pedestal by holder pivots and with linear gear rack engaged transmission, described support is connected with base height is adjustable; One end of second paw is hinged on gear axis, and is provided with the position-limit mechanism of locating for the second paw and gear or throwing off between the second paw and gear, and the other end is pushed against workpiece surface; The second described paw comprises bar portion and head, and bar portion and head are provided with the governor motion of the relative distance for end, adjusting rod portion and head.
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 portion is subject to the elastic force effect of stage clip and moves down along vertical direction; Can rotate around its axis both clockwise by driven gear in the process that guide rod declines, gear will drive the end of the second paw to decline with the upper surface being pressed on workpiece.In addition, when the constraint of the second paw to workpiece surface will be dismantled, first can remove the position-limit mechanism between the second paw and gear, the second paw is thrown off from gear face, then pull guide rod move up just desirable go out workpiece; In addition, to be connected the dismounting that can facilitate gear on the one hand with the adjustable height of pedestal by support, workpiece can also to be facilitated from the dismounting pedestal on the other hand, namely by removal bracket to remove the constraint of the second paw to workpiece surface.Wherein, the length value that can be realized the second paw by the design of governor motion is regulated, thus make the second adjustment of paw end in the overlay area of workpiece surface, namely the end of the second paw can be pressed onto the different position of workpiece surface, improve the scope of application of the second paw therefore, the utility model provides a kind of force value large and the compressing fixture that continuation is good.
Preferred as one, described governor motion refers to, the radial direction in the bar portion of the second paw is provided with first locating hole, and the axis of bar end surface is provided with a cavity, the head of the second paw is axially arranged with bluff body along it, bluff body is slidably connected in cavity, and bluff body is provided with multiple second locating hole, and the first locating hole is connected by alignment pin with the second locating hole; Bluff body is socketed with the second stage clip, the second stage clip is between bar portion and head; Bar portion and head outer wall are provided with sleeve, and sleeve one end and head screw, and other end bar portion outer wall is slidably connected, and sleeve is provided with the open slot of accommodating alignment pin head.When needing the length value of elongation second paw, after can alignment pin being extracted, the head of the second paw of can stretching slides along the inwall of cavity to make bluff body, by the time when the first locating hole in the second paw bar portion aimed at by the next one second locating hole on bluff body, then by alignment pin, bar portion and head are connected as a single entity, this wherein, second stage clip can be provided an elastic force between bar portion and head, head is made to have the trend in a disengagement yoke portion, and this trend provides the active force of different directions can to the two-section up and down of alignment pin, and sleeve and the design of open slot can improve the globality that whole bar portion is connected with head, and arranging of open slot can play an effect of aiming at, details are as follows: when sleeve screws on head, and open slot on sleeve is when aiming at the second locating hole on bluff body, again sleeve and head are inserted in the cavity in bar portion, ensure that the opening of open slot can on the first locating hole in alignment rods portion simultaneously, be exactly so indirect the first locating hole and the second locating hole are aimed at, this just facilitates the grafting of alignment pin.
