Abstract
The invention discloses a turning butterfly-shaped part clamping device which comprises a poking disc, a poking pin and three clamping jaws. The poking disc is a circular boss in a ladder shape. The center of the poking disc is provided with tapered countersinks. The poking disc is provided with a plurality of countersinks. The poking pin is further arranged in the poking disc and used for driving a part to be machined to rotate. The lower end of the poking disc is provided with annularly-distributed trisected grooves. The grooves are communicated with the tapered countersinks. The movable clamping jaws are arranged in the grooves. The ends, close to the center of the poking disc, of the clamping jaws are provided with tapered blocks. When the clamping jaws are contracted to the minimum position with the poking disc as the center, the tapered blocks are annularly distributed to form a positioning circle with a gap. The diameter of the positioning circle is equal to or smaller than the diameter of a center hole of the part to be machined. The turning butterfly-shaped part clamping device is convenient to operate, capable of clamping the butterfly-shaped part, high in machining efficiency and capable of meeting the production requirements, and has good practical value and popularization value, and the butterfly-shaped part cannot be deformed in the machining process.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The clamping device of the of the present invention 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 of the present invention 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.
