The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As Fig. 1, this jig comprises location-plate 1 and positioning disk 2.Comprise location-plate datum level 3, ogive curve face 4 and elastic sheet 5 on the location-plate 1; Comprise positioning disk datum level 6, positioning disk cone key 7, the conical surface 8, V-type groove 9 and positioning round orifice 10 on the positioning disk 2.
Location-plate 1 is to be used for the element of fastening means or workpiece, and positioning disk 2 is the elements that are connected with machine tool chief axis or workbench; Instrument or workpiece accurately connect with the location with lathe makes location-plate cooperate the realization that is located by connecting with positioning disk by axial take-up device.
Uniform four identical openings on the datum level 3 of location-plate 1, between two faces of formation opening certain distance is arranged, and perpendicular to datum level, corresponding with the location-plate opening is that four cone keys 7 are arranged on positioning disk 2, also have on the positioning disk four with cone key 7 bar shaped datum level 6 uniformly at intervals.Along with location-plate 1 and positioning disk further vertically, conical surface platform 7 progresses into the opening of location-plate 1, and makes opening touch the conical surface 8, makes location-plate obtain radial location, when the datum level 3 of location-plate 1 and acquisition axial location after the datum level 6 of positioning disk 2 contacts
As Fig. 2, the side of location-plate 1, datum level 3 has formed arch shrapnel 5 with arched surface 4, and is thinner at an end of opening part, and thicker at root, makes shell fragment 5 existing certain elasticity roots that enough intensity be arranged again.
As Fig. 3, the upper end width of cone key is much smaller than the A/F of location-plate 1, can make conical surface you portion enter opening, and the arch hole of location-plate 1 has enough spaces to hold the cone key that enters opening.When any termination of opening contacted the conical surface 8 of conical surface platform 7, location-plate 1 can move along the conical surface 8, from the radial position of dynamic(al) correction opening and conical surface platform.When corresponding another side opening contacted with the conical surface, location-plate 1 open centre overlapped with the center of cone key, finished the radially correction of location-plate 1 and positioning disk 2 this moment.
As Fig. 4, though location-plate 1 is finished with positioning disk 2 radial locations, axially do not reach stable and connect, still there is small distance between the datum level 3 of location-plate 1 and the datum level 6 of positioning disk 2, when axial clamping force increased, location-plate 1 continued near positioning disk.Opening and the conical surface 8 of location-plate 1 produced the magnitudes of interference and produced strains this moment, this moment opening with the conical surface 8 relative to motionless and location-plate 1 integral body still can move to positioning disk, radial component then makes the enough big radial-thrust force of arch shrapnel generation.
As Fig. 5, location-plate continues under the axial clamping force effect when mobile vertically, and each corresponding surface of datum level 3 contacts with the datum level 6 of positioning disk 2 successively on the location-plate 1, and certain axial compressive force is arranged.Guarantee stability in contact, finish the axial location of location-plate 1.At this moment, the arch shrapnel of location-plate 1 opening part has axial deformation under clamped condition, so it always has a trend that deviates from positioning disk 2.When axial clamping force was eliminated, arch shrapnel 5 can eject positioning disk automatically and break away from positioning disk.
As Fig. 6, the datum level 6 of positioning disk 2 and cone key 7 all are in strip and are evenly distributed on radial position, the connecting of the suitable location-plate 1 with the different size specification of this bar shaped table top.
Further, as Fig. 1, little datum level 11 and cone key 12 is positioned at same radial position with relatively large datum level 6 and conical surface platform, and certain distance is axially arranged, its suitable and littler location-plate 1 is connected, and this positioning disk 2 comprises the neither conical surface platform 7 and the datum level 6 of coaxial aspect.
As Fig. 7, jig comprises location-plate 1 and the positioning disk 2 that is linked together; As Fig. 8,9, this jig comprises location-plate 1 and the positioning disk 2 that need reorientate.
As Fig. 9, location-plate 1 side comprises the V-type groove 9 of two correspondences, is parallel to each other and is parallel to datum level 3, and this V-type groove is convenient to the clamping of manipulator, and the positioning round orifice 10 in the V-type groove is longitudinal register points of manipulator simultaneously.
