Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described.
The clamping device of the described in the utility model a kind of turning butterfly part as shown in accompanying drawing 1-7, comprises driver plate 1, finger 2 and three claws 3; Described driver plate 1 is stepped round boss; Described driver plate 1 center is provided with cone shaped countersink 5; Described driver plate 1 is provided with multiple counterbore 6; Also be provided with finger 2 in described driver plate 1, rotate in order to drive part to be processed; Described driver plate 1 lower end is provided with the trisection groove 7 of annular spread; Described groove 7 communicates with cone shaped countersink 5; Moveable claw 3 is provided with in described groove 7; Described claw 3 is provided with circular cone 4 near the one end at driver plate 1 center; When being retracted to minimum position between described claw 3 centered by driver plate 1, the setting circle that circular cone 4 annular spread becomes to have a gap; Described location diameter of a circle is not more than centre bore 8 diameter of part to be processed; The width of described groove 7 and be highly greater than width and the height of claw 3; Described counterbore 6 is corresponding with the locking screw nail on oild chuck main shaft.
The clamping device of the described in the utility model a kind of turning butterfly part as shown in accompanying drawing 1-7, before processing, first three claws 3 are installed in oild chuck 9, in driver plate 1 a three decile groove 7 is aimed at respectively the position of three claws 3, counterbore 6 simultaneously on driver plate 1 is corresponding with the screw hole of oild chuck 9 main shaft, is then connected with the main shaft of oild chuck 9 is fastening by driver plate 1 with lock-screw 11.
The positioning datum A of part to be processed 12 as shown in Figure 1 and auxiliary base B, adding man-hour, first load part 12 to be processed, oild chuck 9 unclamps, after making to be retracted to minimum position between claw 3 centered by driver plate 1, the setting circle that circular cone 4 annular spread becomes one to have a gap, the centre bore 8 of part 12 to be processed is just in time enclosed within the setting circle that is made up of the circular cone 4 on three claws 3, namely positioning datum A is enclosed within setting circle, the upper surface of auxiliary base B and driver plate 1 is close to, simultaneously finger 2 is through the colored hole 10 of part 12 to be processed and direction of rotation one end when being close to turning, then three-jaw self-centering hydraulic pressure chuck 9 is under the effect of hydraulic jack, three claws 3 open, its three circular cones 4 clamp the positioning datum A of part 12 to be processed, under the effect of three circular cones 4, part 12 meeting to be processed down extrusion and displacement, auxiliary base B and driver plate 1 upper surface of part 12 to be processed are close to, thus make it all can not move in axis and longitudinal direction, then oild chuck 9 rotates, the drive clamping frictional force and the finger 2 produced by the location disjunction mark of part 12 to be processed and the circular cone 4 of claw 3 is treated processing parts 12 and is carried out turnery processing.
After turnery processing completes, three claws 3, under the effect of hydraulic jack, are retracted to minimum position by three-jaw self-centering hydraulic pressure chuck 9, thus unclamp part 12 to be processed, then utilize manipulator or take off the part to be processed 12 processed manually.
The clamping device of turning butterfly part of the present utility model, is applicable to all vertical or horizontal lathes.
The clamping device of turning butterfly part of the present utility model, its easy to operate practicality, can well clamp butterfly part, in process, butterfly part can not be out of shape, working (machining) efficiency is high, well meets the requirement of actual production, has the value of good practical value and popularization.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
