Detailed description of the invention
Below in conjunction with accompanying drawing, utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
As shown in Fig. 1-Fig. 7, a kind of circular hole class Workpiece fixing clamping device, comprising: guide seats 20, guide seats 20 has the first central through hole, and the first central through hole passes guide seats 20 for push rod 10 and carries out spacing to push rod 10; Bearing 40, bearing 40 has columniform extension, and columniform extension is treated in the circular hole of circular hole workpiece 70 of clamping described in inserting, and the diameter of columniform extension is less than the aperture of the circular hole of the circular hole workpiece 70 treating clamping; Have the periphery extended laterally in the bottom of described extension, the diameter of periphery is greater than the aperture of the circular hole of the circular hole workpiece 70 treating clamping; The described guide seats 20 of the dismountable connection of described periphery; Inner chamber, it is arranged on bearing 40 inside and is communicated with described first central through hole; Described inner chamber has multiple opening on the outer peripheral face of described extension, and cavity is in order to hold briquetting 50; Multiple briquetting 50, briquetting 50 correspondence is arranged in described multiple opening, and the inwall of described multiple briquetting forms the spatial accommodation with certain taper; Push rod 10, it has bullet 11, the excircle tapering of described bullet 11 and the inwall taper fit of described briquetting 50; One end of described bullet 11 has the first bar, and it is through described first central through hole; Wherein, when described first bar is along when moving from described rest base to top-direction, described bullet 11 applies outside extruding force to multiple briquetting 50, thus makes described multiple briquetting 50 extrude the inwall of described circular hole workpiece.
In installation process, first briquetting 50 is put into the cavity of bearing 40, push rod 10 is put into the spatial accommodation with certain taper formed between multiple briquetting 50, then bearing 40 is flexibly connected with guide seats 20.Then push rod 10 is pulled back, again fixture is inserted in the circular hole of circular hole workpiece 70, driven forward push rod 10 again, the bullet 11 of push rod 10 advances in spatial accommodation, bullet 11 extrudes multiple briquetting 50 laterally, thus make described multiple briquetting 50 extrude the inwall of described circular hole workpiece, and then realize fast to circular hole workpiece 70 clamping.When needs unclamp workpiece 70, pull back push rod 10, the bullet 11 of push rod 10 retreats and extrudes multiple briquetting 50 no longer laterally in spatial accommodation, thus realizes being decontroled by workpiece 70 fast.
In another embodiment, also comprise flexible member 60, flexible member 60 applies the power inwardly fastened to briquetting 50, for fastening described multiple briquetting, thus prevent briquetting to be scattered.When needs unclamp workpiece 70, push rod 10 moves backward, and the bullet 11 of push rod 10 retreats in spatial accommodation, extrude multiple briquetting 50 no longer laterally, multiple briquetting 50 is under the effect of flexible member 60, and briquetting 50 inwardly closes up, thus realizes being decontroled by workpiece 70 fast.
In another embodiment, flexible member 60 is the elastic circular rings with opening, it is arranged in the common annular groove formed of described multiple briquetting 50, flexible member can make it more even to the power of the inside fastening that briquetting applies in annular groove, and annular groove limits the position of flexible member 60 in briquetting, prevent it from sliding and coming off.
In another embodiment, the top of described bearing 40 has the second central through hole, and the other end of described bullet has the second bar, and it is through described second central through hole.Through the first central through hole and the second central through hole, push rod effectively can ensure that push rod moves along the axis direction of a dress clamping device, the precision of the clamping device of guarantee in promotion putting strokes successively.
In another embodiment, the tapering of described bullet is 8 ~ 15 °, in this angular range, and shape self-locking structure in the slope between cone tank and bullet 11.Namely, when driven forward push rod 10, bullet 11 and spatial accommodation can auto locks, can not slide.
In another embodiment, be flexibly connected by dormant bolt 30 in described guide seats 20 and bearing 40, be more convenient to dismounting.
In another embodiment, be provided with anti-slip rubber at described push rod 10 end, the frictional force of push rod end can be increased, thus convenient operation personnel dragging and pull-out push rod 10 can be added.
In another embodiment, be provided with screw thread at described push rod 10 end, the frictional force of push rod end can be increased, thus convenient operation personnel dragging and pull-out push rod 10 can be added.
As mentioned above, the utility model can not only realize fast, clamps reliably and unclamp circular hole class workpiece 70; Accurately can also locate circular hole class workpiece 70.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
