Fig. 2 is the partial enlarged drawing a of the utility model Fig. 1.
In figure: 1. frame, 2. bearing support, 3. cam, 4. cam fulcrum bearing, 5. handle, 6. tapered sleeve, 7. elastic clip cylinder, 8. rotation stopping screw, 9.l shape pressing plate, 10. bearing pin, 11. spacing adjusting screws, 12. supporting screws, 13. adjusting nuts, 14.u type Groove, 15. domes, 16. screw mounting grooves, 17. clamping spring washers, 18. annular knurls, 19. multidiameters, 20. fixed supports.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following examples are right Of the present utility model explain and the utility model is not limited to following examples.
As depicted in figs. 1 and 2, a kind of adjustable clamping device for multidiameter, it include frame 1, bearing support 2, Cam 3, cam fulcrum bearing 4, handle 5, tapered sleeve 6, elastic clip cylinder 7, rotation stopping screw 8, l shape pressing plate 9, bearing pin 10, spacing regulation spiral shell Nail 11, supporting screw 12, adjusting nut 13, fixed support 20, described bearing support 2 is fixed in frame 1, described cam supporting Seat 4 is arranged in frame 1, and described cam 3 is rotatably provided in cam fulcrum bearing 4, and one end of described handle 5 and cam 3 are solid Fixed connection, the other end of described handle 5 is provided with annular knurl 18, is conducive to operating personnel that handle 5 is gripped, substantially increases The convenience of operation.The lower end of the endoporus of described cam 3 and elastic clip cylinder 7 is threaded, and described elastic clip cylinder 7 can slide up and down It is arranged in tapered sleeve 6, described tapered sleeve 6 is arranged on bearing support 2, the inner side of described elastic clip cylinder 7 upper end is provided with clamping bullet Pad 17, decreases crushing of multidiameter 19 in clamping, significantly protects multidiameter 19.It is provided with u-shaped on described elastic clip cylinder 7 Groove 14, described rotation stopping screw 8 is arranged on bearing support 2, and inserts in u-shaped groove 14, and described fixed support 20 is arranged on and props up Hold the upper end of bearing 2, described l shape pressing plate 9 is hinged on fixed support 20 by bearing pin 10.Described supporting screw 12 is threaded In the lower end of l shape pressing plate 9, one end of described supporting screw 12 is provided with dome 15, is conducive to fitting with cam 3.Described supporting Adjusting nut 13 is also threaded with screw 12.The screw mounting groove 16 of level, described spacing tune are provided with bearing support 2 Section screw 11 is threadably mounted on screw mounting groove 16, and described spacing adjusting screw 11 is slotted head screw, is easy to spacing adjustment The adjustment of screw 11 position.
By technique scheme, when a kind of adjustable clamping device for multidiameter of the utility model uses, operation During personnel's gripping handle 5 rotation cam 3, the endoporus due to cam 3 is threadeded with elastic clip cylinder 7, and elastic clip cylinder 7 is subject to rotation stop The restriction of screw 8 can not be turned round, therefore it will move down and contraction distortion in the presence of tapered sleeve 6, the thin diameter section of multidiameter 19 Clamped by centering.On the other hand, cam 3 forces two l shape pressing plates 9 to clamp the wide section of multidiameter 19 to swing.Pass through The adjustment of spacing adjusting screw 11 position, the adjustment of achievable l shape pressing plate 9 amplitude of fluctuation.When clamping force needs adjustment, unscrew Adjusting nut 13, the position of adjustment supporting screw 12, then tighten adjusting nut 13 again.When supporting screw 12 adjusts laterally, Clamping force diminishes;Supporting screw 12 to inner side adjust when, clamping force becomes big.The utility model not only enables to multidiameter 19 Quick-clamped, and clamping force is adjustable, strong applicability.
Above content described in this specification is only to the utility model example explanation.The utility model Person of ordinary skill in the field can make various modifications or supplement or adopt class to described specific embodiment As mode substitute, the content without departing from the utility model specification or surmount model defined in the claims Enclose, protection domain of the present utility model all should be belonged to.
