Specific implementation mode
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
A kind of numerically-controlled machine tool index table as shown in Figure 1 has pedestal 15, workbench 4 and is mounted on the bottom
Supporting rack 18 between seat 15 and workbench 4, supporting rack 18 and the middle position of workbench 4 are equipped with central shaft 7, central shaft
7 are arranged with piston 8 on supporting rack 18 and are fixed by bearing arrangement 16,
Equipped with lower sealing block 21 between piston 8 and supporting rack 18, the upper sealing block 5 being fixed on lower sealing block 21,
The lower end of workbench 4 is equipped with groove, and end-toothed disc 10 is fixed on the inner wall of groove, opposite with groove inner wall
The lower end-toothed disc 11 that setting is engaged with upper end-toothed disc 10 is fixed on the supporting rack 18 answered；
The lower end of workbench 4 is equipped with gear wheel 12, and holder 22, holder 22 are equipped between workbench 4 and supporting rack 18
It is upper that the pinion gear engaged with gear wheel 12 is equipped with by axis, worm couple 19 is also equipped on axis；
The cavity formed between piston 8 and upper sealing block 5 is upper oil cavitie 9, the sky formed between piston 8 and lower sealing block 21
Chamber is lower oil cavitie 17, is connect with oil duct 14 on upper oil cavitie 9 and lower oil cavitie 17.
Microswitch 13 is also equipped on supporting rack 18.
Axis is to float to be arranged, and has thrust ball bearing 20 in the axial direction of axis, and resist spiral by thrust ball bearing 20
Above spring 23.
It is so that oil is entered lower oil cavitie 17 by oil duct 14 that specific workbench 4, which needs to unclamp when indexing, and piston 8 is made to transport upwards
It is dynamic, while thrust bearing 6 makes central shaft 7 move upwards, to which workbench 4 also moves up, end-toothed disc 10 and lower end in realization
Fluted disc 11 is disengaged from, to realize that indexing action is ready.
After the completion of the indexing of workbench 4, needing to decline makes workbench 4 clamp, and fluid can enter upper oil cavitie 9 from oil pipe 14,
Make that piston moves downward, central shaft 7 drives workbench 4 to decline, and upper end-toothed disc 10 and lower end-toothed disc 11 are from new engagement, and with closing
End-toothed disc 10 and the positioning of the bolt of the circle distribution on lower end-toothed disc 11 slightly position, and realize the clamping and positioning of workbench 4.
When workbench needs indexing, certain altitude is risen to, pinion gear and gear wheel 12 is made to engage, standard is carried out for indexing
It is standby, microswitch 13 is pushed by push rod 1, sends out signal, pressure oil enters hydraulic motor from pipeline makes its rotation.Pass through worm gear
Worm gear pair 19, upper end-toothed disc 10 and lower end-toothed disc 11 drive workbench 4 to carry out indexing rotary motion.When the angle of revolution of workbench 4
When spending close to the angle of required indexing, block 2 makes microswitch 1 act, and reduce-speed sign is sent out, when hydraulic motor stops operating
Afterwards, i.e., workbench completes dividing movement, solenoid valve power-off.Pressure oil enters hydraulic cylinder epicoele from pipeline, pushes piston 8 with work
Make platform decline, then upper lower tooth disk completes positioning and clamping again from new engagement.
There is the transmission worm gear worm gear pair 19 of index table self-locking performance, i.e. movement cannot reach worm screw from worm gear.But work as
Workbench declines, and from when new engagement, fluted disc drives gear wheel 12, worm gear to will produce small turn for upper end-toothed disc 10 and lower end-toothed disc 11
It is dynamic.For this purpose, axis is designed to floating structure, and it is axial to be resisted above a helical spring with upper and lower two thrust ball bearings, it works
When the small revolution of platform, worm gear drives worm screw compressed spring to do micro axial movement, completes positioning and clamps.
The above embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with this skill
The personage of art can understand the content of the utility model and be implemented, and the protection model of the utility model can not be limited with this
It encloses, it is all according to equivalent change or modification made by the spirit of the present invention essence, it should all cover the protection model in the utility model
In enclosing.
