Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described.
Described in the utility model a kind of butterfly hole in piece part positioning fixture as shown in accompanying drawing 1-9, comprises chuck body 1, finger 3, mandrel 4, conical head bolt 5, threaded sleeve 6, pivot pin 7 and spring 8; Described chuck body 1 is connected with oild chuck 2; Described chuck body 1 is provided with the finger 3 with the corresponding setting of installing hole 15 of butterfly part 14; Through hole 9 place at described chuck body 1 center is provided with mandrel 4; Described mandrel 4 top is tapered; The diameter of described taper large end face is identical with endoporus 16 diameter of butterfly part 14; Described mandrel 4 center has taper hole 10; Conical head bolt 5 is provided with in described taper hole 10; Described conical head bolt 5 is connected with the hydraulic jack 13 in oild chuck 2; The multiple telescopic holes 11 about the distribution of taper hole 10 upper end circular array are provided with in described mandrel 4; Described telescopic hole 11 communicates with taper hole 10; Be provided with by the coupled pivot pin 7 of threaded sleeve 6 in described telescopic hole 11; Described pivot pin 7 is provided with spring 8; When described conical head bolt 5 moves down, extruding pivot pin 7 does the action of stretching out; Described conical head bolt 5 drops to certain position Shi Dai moving mandrel 4 and moves down, and makes pivot pin 7 push down the upper surface 17 of endoporus 16; Described mandrel 4 top is positioned at above taper hole 10 and is also provided with dust cap 12; Described dust cap 12 is threaded with mandrel 4; Described threaded sleeve 6 is fixed in telescopic hole 11 by location spiral pin (not shown); The quantity of described telescopic hole 11 is three; Described conical head bolt 5 is connected with the expansion link screw thread of hydraulic jack 13; Described chuck body 1 is connected with oild chuck 2 screw thread.
Described in the utility model a kind of butterfly hole in piece part positioning fixture as shown in accompanying drawing 1-9, before carrying out the processing of butterfly part, first unclamp oild chuck, in oild chuck, the expansion link of hydraulic jack rises, thus drive conical head bolt to rise, then pivot pin gets back to original position under the force of a spring; The upper surface of chuck body put into butterfly part by the top conical surface aiming at mandrel by the endoporus of butterfly part, thus ensure that butterfly class part can not move in the vertical, pulled pin by multiple in chuck body simultaneously and to be connected with the installing hole on butterfly part, butterfly class part is connected with chuck body, like this when oild chuck rotates, butterfly class part can be driven to rotate together convenient to its cutting; Then oild chuck clamping, the expansion link of the hydraulic jack in oild chuck declines, and drive conical head bolt to decline, such three pivot pins just stretch out in telescopic hole in the extruding of conical head bolt; When pivot pin reaches desired location, conical head bolt pulls mandrel to move down, thus make three pivot pins push down the upper surface of processed butterfly inner bore of part, ensure that butterfly part can not move in the axial direction, lathe open belt hydrodynamic pressure chuck rotates, and the butterfly part of lathe tool to thin class carries out the Vehicle Processing of end face and cylindrical; After turning completes, oild chuck unclamps, hydraulic jack in oild chuck rises, and drives conical head bolt up to move, pulls mandrel up to move when conical head bolt up moves, three pivot pins get back to home position under the force of a spring simultaneously, finally thin class butterfly part are taken off.
