Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of turret knife tower, particularly a kind of indexing means of turret knife tower turntable.
Background technology
Install different cutters on the turret knife tower additional, in its course of work, need constantly replace suitable cutter and carry out cutwork, the cutter that both will need to use forwards the workbench place to and carries out work, and transfer originally was in the cutter at workbench place, therefore, turret knife tower is provided with an indexing means, and this indexing means makes the cutter tower by cutter preset program rotation work.Under the general situation, driving the scheme that the cutter tower rotates is directly to rotate by motor direct-drive cutter tower, and this scheme has its outstanding one side, but its shortcoming also clearly, and, cutwork scope not high as positioning accuracy is limited in the single direction etc.
And Chinese patent application number is 200620160186.8 " revolving three-sixth turn power servo turret seat automatically arbitrarily " these shortcomings have been done further improvement, it discloses lathe seat, cutter tower tray, cutter tower and cutter tower whirligig, cutter tower tray periphery can be inserted with at least one cutter tower, then is respectively arranged with various required cutter in the cutter tower.Wherein, after the cutter tower that is provided with required cutter turns to the predetermined work zone with the cutter tower tray, cutter tower whirligig can rely on its contained servo motor interlock associated components, makes the cutter tower that is equipped with required cutter can do the arbitrarily rotation of 360 degree according to need, but and makes the processing action of cutter multi-angle.Cutter tower whirligig comprises servo motor, drive link, connect the travelling gear that is located at this drive link and be meshed with this travelling gear and connect the gear ring of establishing, this drive link and this servo motor connect, and can be located in this cutter tower tray, be meshed with the connector of those driven gears and this gear ring is eccentric, in order to drive this driven gear, make in this cutter tower of the further interlock of this driven gear and rotate this cutter tower.
This cutter tower whirligig adopts gear drive, can't locate by gear in aligned cutting tool, so locating accuracy is bad, thereby has influenced the processing to part; Secondly, use gear drive, make the volume of integral body of cutter tower become heavy.
Summary of the invention
The purpose of this utility model is the above-mentioned problem at the indexing means existence of existing turret knife tower turntable, and the indexing means of the turret knife tower turntable that a kind of compact conformation is simple, positioning accuracy is high is provided.
The purpose of this utility model can realize by following technical proposal: a kind of indexing means of turret knife tower turntable, described turret knife tower comprises cutter tower support and the rotating disk that is arranged on the cutter tower support, this indexing means is arranged between cutter tower support and the rotating disk, comprise and be arranged on rotating calibration rotating shaft on the cutter tower support, it is characterized in that, described rotating disk has the ennation of the tubular that extends vertically, above-mentioned calibration rotating shaft is arranged on the sidepiece of ennation and vertical mutually with ennation, in the calibration rotating shaft, be fixed with cylindrical cam, be provided with the step by step structure that when the calibration rotating shaft is rotated, drives the ennation rotation between cylindrical cam and the ennation.
The indexing means of this turret knife tower turntable can make angle of dial rotation under the drive of motor, make the cutter on the rotating disk move to the position that needs.Because rotating disk is rotating being connected on the cutter tower support, and the ennation on the rotating disk can drive dial rotation, calibration rotating shaft and ennation at the sidepiece of ennation vertically are provided with, make this calibration device become compact, when the rotating shaft of motor-driven calibration is rotated, cylindrical cam in the calibration rotating shaft drives angle of ennation rotation by step by step structure, thereby realizes angle of dial rotation.
In the indexing means of above-mentioned turret knife tower turntable, described step by step structure comprises several the uniform pins on the same circumference that is fixed on the ennation outside, have spiralling groove on the lateral surface of above-mentioned cylindrical cam, described pin has at least one to be in the groove and each root pin all can be from the lower end of groove and upper end turnover.The pin that is arranged on the ennation is in the groove of cylindrical cam, the rotary cylinder cam, because groove is spiralling, in the rotation process of cylindrical cam, pin can rise until making pin leave groove from the upper end of groove along groove; When a pin was pushed away groove, next adjacent pin then just was in the lower end of groove, entered circulation next time.Circulation each time, ennation are pushed angle of rotation, make angle of the corresponding rotation of rotating disk.Therefore, pin is to be distributed on the outside of ennation and just can to realize such linking on by individual circumference.
In the indexing means of above-mentioned turret knife tower turntable, the port of described groove lower end has one section straight trough inlet 14 along the surperficial circumferential straight setting of cylindrical cam.During work, rotating disk is by a latch-up structure that rotating disk is fixed, and when rotating rotating disk, latch-up structure need be opened and make rotating disk recovery rotation.Before opening latch-up structure, rotating disk is fixed and can not rotates, when cylindrical cam rotates, cylindrical cam cannot drive pin and rise along groove, therefore, end entrance has one section straight trough inlet 14 along the circumferential straight setting of cylindrical cam under groove, makes cylindrical cam can not interfere the rotation of cylindrical cam.After latch-up structure was opened, pin reached the terminal point of straight trough inlet, and beginning is risen along groove.
In the indexing means of above-mentioned turret knife tower turntable, described pin one end is fixed on the ennation by screw thread, and the other end is with roller, is connected by bearing between pin and the roller.Putting roller on the pin is in order to reduce the frictional force between pin and the groove.
In the indexing means of above-mentioned turret knife tower turntable, be fixed with indexing motor on the described cutter tower support, be provided with the transmission mechanism that the calibration rotating shaft is rotated between the rotating shaft of this indexing motor and the calibration rotating shaft.
In the indexing means of above-mentioned turret knife tower turntable, transmission mechanism comprises connecting axle, one end of connecting axle is connected by shaft joint with above-mentioned calibration rotating shaft, and the other end is fixed with gear wheel, is provided with the pinion with the gear wheel engagement in the rotating shaft of indexing motor.
In the indexing means of above-mentioned turret knife tower turntable, described indexing motor adopts servomotor or stepper motor.
Compared with prior art, the indexing means of this turret knife tower turntable has following advantage:
1, in the indexing means of this turret knife tower turntable, calibration rotating shaft and ennation vertical setting mutually make this calibration apparatus structure compact more, and volume reduces.
2, the structure that groove and pin be set between calibration rotating shaft and ennation realizes the step-by-step system to rotating disk, and is simple in structure, and stepping progress height.
