Detailed description of the invention
See Fig. 1 and Fig. 2: the utility model comprises main base 1 and driver plate 2.Wherein, main base 1 is Morse taper shank, its front end surface has indent die cavity, when clamping uses, main base 1 for insert in the pilot hole of machine tool chief axis, ensure centering and realize self-locking and be connected.
Driver plate 2 is disc structure broad in the middle small in ends, and namely its appearance profile is crosswise; The end of driver plate 2 towards main base 1 is defined as rear end, is defined as front end towards the end of part 14.The rear end of driver plate 2 has indent die cavity, and the external diameter of this indent die cavity is less than the indent die cavity on main base 1 and the indent depth of cavity on the corresponding main base 1 of evagination length.The center, front end of driver plate 2 is provided with center hole 12, with three pin-and-holes 13 of center hole 12 annular spread, no matter be that center hole 12 or pin-and-hole 13 all communicate with the indent die cavity of driver plate 12 rear end.Be arranged with the calibration chute 10 of two sections of arcuations outside the pin-and-hole 13 of driver plate 2, the track of calibration chute 10 answers the assembling point of corresponding driver plate 2 on main base 1; The angle that the two ends of every section of calibration chute 10 and driver plate 2 center are formed selects within the scope of 90 ~ 150 ° that (larger versatility is better, but need the structural strength considering fit on, preferably 120 ~ 140 °), the driver plate surface at calibration chute 10 place or outer rim are provided with calibrated dial; Two sections of calibration chutes 10 are symmetrical on driver plate 2.
Above-mentioned driver plate 2 is assemblied on main base 1 by the double threaded screw 8 that installs two sections of calibration chutes 10 in and locking nut 9, namely driver plate 2 with double threaded screw 8 for basic point can the rotation on main base 1 along the arching trajectory of calibration chute 10, realize corresponding calibration.Aforementioned assembly structure makes the rear end of driver plate 2 extend into the indent die cavity of main base 1, is provided with the hermetically-sealed construction sealed mutually with driver plate 2 rear end in the indent die cavity of main base 1, adopts the sealing ring 11 in annular groove to form sealing in the present embodiment.In the center hole 12 of aforementioned driver plate 2, sealing is equipped with center top 3, and in three pin-and-holes 13, sealing is equipped with drive pin 4 respectively.The space that forms is sealed built with flexible media 5 at aforementioned driver plate 2 indent die cavity and main base 1 indent die cavity, the present embodiment adopts liquid plastics, this flexible media 3 and center hole 12 Nei Suozhuan center top 3 and pin-and-hole 13 interior fill drive pin 4 rear end contact respectively.Thus when clamping uses, tailstock centre 15 holds out against part 14, and this pressure acts on center top 3, and center top 3 inside contracts, extrudes flexible media 3, the wave action of flexible media 3 on drive pin 4, make drive pin 4 firmly compressing component 14, to realize drive actions.
It also can be split suit that the rear end that above-mentioned driver plate 2 extends into main base 1 is provided with integrated worm gear 6().In main base 1, be equipped with the worm screw 7 be meshed with aforementioned worm gear 6 by parts such as bearings, the die cavity that main base 1 is extended in one end of this worm screw 7 is connected with power source.When clamping uses, power source inputs rotary power to worm screw 7, worm screw 7 drives worm gear 6 to rotate, worm gear 6 drives driver plate 2 on main base 1, to do corresponding rotation for basic point with double threaded screw 8 along calibration chute 10 arching trajectory, certainly in the action of rotary index, locking nut 9 unclamps relatively, screw again after calibration puts in place realize fastening.
Based on said structure principle of the present utility model, can also worm gear is arranged on the outer ring of driver plate, worm screw is arranged on the outside of main base, but this will increase structural volume, thus preferred said structure.
Above-mentioned concrete technical scheme, only in order to the utility model to be described, is not intended to limit.Although be described in detail the utility model with reference to above-mentioned concrete technical scheme, those of ordinary skill in the art has been to be understood that: it still can be modified to above-mentioned concrete technical scheme, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of technical solutions of the utility model.
