The specific embodiment
At Fig. 1, Fig. 2, Fig. 3, among Fig. 4, the utility model comprises circular index workbench 1, but active toothed disk 2, fixed gear plate 3, fastening fluted disc 4, base 9, revolution ball 5, upper push-rod 7 and lower support seat 10, base 9 centres are fixed with the upper end and are the lower support seat 10 of spill conical bore, revolution ball 5 is housed in the spill conical bore, the first half of revolution ball 5 is exposed the spill conical bore, the first half of revolution ball 5 is included in the spill conical bore of circular index workbench 1 downside centre bit, annular fixed gear plate 3 following supporting bases 10 are that center fixation is on base 9, but annular active toothed disk 2 is positioned at fixed gear plate 3 outsides, following supporting base 10 is fixed on circular index workbench 1 downside for the axle center, fastening fluted disc 4 warp beam sleeves of annular are installed on the lower support seat 10, following supporting base 10 is the axle center, but be installed in fixed gear plate 3 and active toothed disk 2 tops, fastening fluted disc 4 can rotate and can move up and down along the axis direction of lower support seat 10 around lower support seat 10, fastening fluted disc 4 moving downward or upward along the lower support axle, but can realize engagement with fixed gear plate 3 and active toothed disk 2, separate, the downside of circular index workbench 1 is equipped with the revolution locking key 6 that can cooperate with fastening fluted disc 4 lockings, when ball 5 rotations are changeed in 1 wraparound of circular index workbench, under the effect of revolution locking key 6, can drive fastening fluted disc 4 and rotate.But active toothed disk 2 is divided into 12 sections along the sector direction by 12 equal portions, is processed with the taper flank of tooth at three 30 ° of angles on the fixed gear plate 3, and the angle between adjacent two flank of tooth center lines is 120 °, and the fixed gear plate 3 between adjacent two flank of tooth is a shiny surface.But the upper disk surface of active toothed disk 2 is lower than the upper disk surface of fixed gear plate 3, but active toothed disk 2 downsides, three taper flank of tooth position of center line of fixed gear plate 3 are respectively equipped with a upper push-rod 7, be that angle between adjacent two upper push-rods 7 is a hexagonal angle, when but calibration need to finish fastening fluted disc 4 to mesh with fixed teeth with active toothed disk 2, fastening fluted disc 4 descends and promotes upper push-rod 7 and moves upward, but realize rigid engagement near fastening fluted disc 4 thereby promote active toothed disk 2, but active toothed disk 2 is fixed on the downside of circular index workbench 1 through set bolt 8, but the height and position of set bolt 8 fine-tuning active toothed disks 2, thereby but make the upper surface of active toothed disk 2 lower than the upper surface of fixed gear plate 3.
But be processed with the concave-convex tooth respectively on the taper surface of the utility model active toothed disk 2, fixed gear plate 3 and fastening fluted disc 4, these teeth have 72 teeth or 144 teeth on circumference ... Deng, promptly having can be the tooth of the quantity of 360 ° of angle five equilibriums, can carry out the calibration of special angle by being meshing with each other of concave-convex tooth, but 360 ° of angle active toothed disks 2 are divided into 12 five equilibriums, become 12 sections, but 3 of fixed gear plates stay 3 parts of tooth that are equivalent to 2 one sections of active toothed disk, remove and remove other profiles of tooth, but the utility model active toothed disk 2 also can be divided into 24 or 36 equal portions.
Present embodiment is to be the calibration purpose with 0 °, 90 °, 180 °, 270 ° 4 positions, fastening fluted disc 4 is when calibration begins, break away from fixed gear plate 3, under the effect of revolution locking key 6, but active toothed disk 2 and circular index workbench 1 can rotate together, circular index workbench 1 is the center by rotary motion mechanism with revolution ball 5, rotates on the slip face of deadweight of carrying workbench and stow loading.During circular index workbench 1 indexing position fixed turning to, fastening fluted disc 4 descends and at first meshes with fixed gear plate 3, and then next fastening by the fastening force of fixed gear plate 3 effects, promptly by three taper flank of tooth on the aforementioned fixation fluted disc 3 and 4 engagements of fastening fluted disc.But active toothed disk 2 engagement height are below fixed gear plate 3, be set at one section difference, therefore the engagement with fastening fluted disc 4 highly just produces the gap, but three taper flank of tooth position of center line of active toothed disk 2 downsides, fixed gear plate 3 are respectively equipped with a upper push-rod 7, upwards promote upper push-rod 7, but the section that then is pushed active toothed disk 2 moves up, thereby but the section of active toothed disk 2 and fastening fluted disc 4 mesh the revolution of restriction circular index workbench 1 by certain power.
The utility model circular index workbench 1 is be that the center is turned round with revolution ball 5, so can obtain high property and the runout precision of feeling relieved.
The utility model can carry out the adjustment of indexing accuracy in the following order:
1, but the set bolt 8 of fixing active toothed disk 2 is in relaxation state.
2, fastening fluted disc 4 is promoted downwards, engages fixed is on fixed gear plate 3.
3, measure the benchmark and the mechanical movement benchmark of circular index workbench 1, its margin of error is come round-off error by the centre of gyration is forwarded to the center.But (because of the section and 6 of the locking keys of revolution of the active toothed disk 2 outside the fixed gear plate 3 upper conical flank of tooth positions gapped, so can rotate)
4, upwards promote upper push-rod 7, but allow the section of active toothed disk 2 and 4 engagements of fastening fluted disc of fixed gear plate 3 upper conical flank of tooth positions.
5, tighten set bolt 8, but a section on the aforementioned active toothed disk 2 is fixed on the circular index workbench 1.
6, same operating procedure is carried out on 0 °, 90 °, 180 °, 270 ° 4 positions respectively, thus the indexing accuracy can adjust 0 °, 90 °, 180 °, 270 ° respectively the time.
