In view of this, the technical problems to be solved in the utility model is to provide a kind of revolving body workpieces circumference drilling jig, is rotated, boring accurate positioning by this fixture clamping workpiece circumference batch (-type).
Revolving body workpieces circumference drilling jig of the present utility model, comprise pedestal and fixture, the rotating shaft that described fixture connects successively, disk, joint pin and positioning sleeve, described rotating shaft and pedestal are rotatably assorted, described rotating shaft, disk and positioning sleeve are coaxially arranged, described joint pin is that circumference is uniform multiple, and described positioning sleeve is by fixing for workpiece circumference.
Further, the cylindrical of described positioning sleeve is connected with flexure strip, the bottom of described flexure strip is provided with the radial locating dowel extended, and to there being the through hole passed for locating dowel on described positioning sleeve, described locating dowel is inserted in the installing hole of surface of the work by through hole.
Further, the bottom of described locating dowel is projection curved vertically, and this projects through workpiece spindle to the locating hole moving forward into out surface of the work.
Further, the free end of described rotating shaft is the screw rod through pedestal, and described screw rod is combined with the nut that can move axially clamping mechanism.
The beneficial effects of the utility model: revolving body workpieces circumference drilling jig of the present utility model, comprise pedestal and fixture, the rotating shaft that described fixture connects successively, disk, joint pin and positioning sleeve, described rotating shaft and pedestal are rotatably assorted, described rotating shaft, disk and positioning sleeve are coaxially arranged, described joint pin is that circumference is uniform multiple, and described positioning sleeve is by fixing for workpiece circumference.Rotated by this fixture clamping workpiece circumference batch (-type), boring accurate positioning.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is floor map of the present utility model;
Fig. 3 is A-A sectional view (90-degree rotation) in Fig. 2.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the revolving body workpieces circumference drilling jig of the present embodiment, comprise pedestal 1 and fixture 2, the rotating shaft 21 that described fixture 2 connects successively, disk 22, joint pin 23 and positioning sleeve 24, described rotating shaft 21 is rotatably assorted with pedestal 1, described rotating shaft 21, disk 22 and positioning sleeve 24 are coaxially arranged, described joint pin 23 is that circumference is uniform multiple, the concrete quantity of joint pin 23 wants the quantity of machining hole identical with workpiece 100 circumference, specific in the present embodiment, workpiece 100 to be processed the 5 row holes 101 that circumference is uniform, so, the quantity of joint pin is 5, 5 joint pins be positioned at same circumferentially and circumference equiangularly namely 72 ° of intervals, workpiece 100 clamping together rotates with positioning sleeve 24 in positioning sleeve 24.The clearance-type rotating drive to fixture 2 can be realized by sheave, sheave has slotted eye, slotted eye is radially extended to center position by sheave circumference, and sheave rotates, and joint pin 23 enters in slotted eye, joint pin can make fixture 2 rotate 72 ° in a slotted eye, the slotted eye of sheave contacts with 5 joint pin clearance-types successively, thus the clearance-type realizing fixture 2 rotates, and fixture 2 often rotates once, just hole once by drilling machine to workpiece, boring accurate positioning.
Positioning sleeve 24 can in an interference fit by workpiece 100 clamping, and to drive workpiece 100 to rotate, but such installation way Problems existing is, workpiece 100 is in positioning sleeve 24 dismounting inconvenience.And in the present embodiment, the cylindrical of positioning sleeve 24 is connected with flexure strip 3, flexure strip 3 has the root connected with positioning sleeve and the end that can radial upwards swing, the bottom of its end is connected with the radial locating dowel 31 extended, to there being the through hole 25 passed for locating dowel on positioning sleeve 24, locating dowel 31 is inserted in the installing hole 102 of surface of the work by through hole 25, realize workpiece 100 clamping on positioning sleeve 24 in the installing hole 102 being inserted workpiece by locating dowel 31, when positioning sleeve 24 rotates, the locating dowel 3 of flexure strip makes workpiece rotate with it by the hole wall of transmission installing hole 102, during dismounting workpiece, as long as make the locating dowel 31 place end of flexure strip 3 is put, locating dowel 31 leaves the installing hole 102 on workpiece 100.
During for making dismounting workpiece, locating dowel 31 automatically disengages and enters installing hole 102, the bottom of locating dowel 31 is projection 32 curved vertically, when installing workpiece, workpiece moves axially, and flexure strip is so that certain elastic force to be put, protruding 32 slide at surface of the work, when projection 32 is relative with the installing hole 102 of surface of the work, protruding 32 enter in installing hole 102, complete clamping workpiece.After the boring of workpiece circumference, travelling workpiece backward, because protruding 32 is axially curved, installing hole 102 moves axially in process and can upwardly 32 make locating dowel 31 leave installing hole 102, thus completes automatic threshing workpiece.
As the further improvement of technique scheme, the free end of described rotating shaft 21 is the screw rod 26 through pedestal 1, and described screw rod 26 is combined with the nut 4 that can move axially clamping mechanism.Adjusting nut 4 can make screw rod 26 and fixture 2 move axially, thus matches with support, realizes workpiece spindle to accurate location.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
