Description
Technical field
This utility model belongs to machining equipment, a kind of digital controlled rotary indexing means in Digit Control Machine Tool.
Background technology
In Digit Control Machine Tool processing workpiece fabrication, need to use digital controlled rotary indexing mechanism that the workpiece such as drill bit, screw tap is carried out rotary index.Current numerical control scale-division mechanism generally includes output shaft, drives output shaft to carry out drive mechanism, the motor of drive transmission device, the flange for clamping workpiece being arranged on output shaft or fixture that indexing rotates, mainly has following several according to the difference of the drive mechanism kind of drive:
1, numerical control worm gear indexing mechanism, its structure is to drive output shaft by worm-and-wheel gear, is realized the rotary index of workpiece by the accurately output of the numerical-control motor control worm and gear anglec of rotation.This mode is the highest to the requirement on machining accuracy of worm and gear, relatively costly, and worm and gear is frictional drive, easily weares and teares, thus loses indexing accuracy.
2, Timing Belt or gear drive indexing mechanism, drives output shaft by Timing Belt or gear mechanism, is realized the rotary index of workpiece by the precise movement of numerical-control motor control Timing Belt or gear mechanism.Although this mode simple in construction, cost are relatively low, but Timing Belt or gear drive have bigger drive gap unavoidably, directly affects the raising of indexing accuracy.
3, direct driving motor indexing mechanism, this mode indexing accuracy is high, but owing to workpiece is directly installed on motor output shaft by needs, when processing large-scale workpiece, it is difficult to produce big specification direct driving motor installation supporting with it, limits the specification limit of processing workpiece.And due to direct driving motor many employings servomotor, with high costs, use field is restricted.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, low cost indexing accuracy digital controlled rotary indexing means high, nonabradable.
Digital controlled rotary indexing means of the present utility model includes output shaft, and output shaft front end is provided with the flange for clamping workpiece or fixture, and output shaft is driven by drive mechanism by numerical-control motor；Being also equipped with detecting the encoder of output shaft swing offset on described output shaft, the signal output part of encoder is connected to control unit, and the control signal outfan of control unit is connected to numerical-control motor drive circuit, is controlled numerical-control motor.
Further, described output shaft back segment is arranged in a cabinet by bearing, and encoder also is located in cabinet.
Further, described drive mechanism is Worm and worm-wheel gearing, and the worm gear of Worm and worm-wheel gearing is arranged on output shaft and is positioned at cabinet.
Further, described drive mechanism is synchronous belt drive mechanism or gear drive.
Further, described control unit includes PLC module or one-chip computer module or motion controller.
This utility model simple in construction, manufacture and easy for installation, low cost；Owing to the encoder by being arranged on output shaft directly gathers output shaft corner information, it is to avoid the median error of indexing process, indexing accuracy can be greatly improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment one；
Fig. 2 is the structural representation of this utility model embodiment two.
Detailed description of the invention
As it can be seen, this digital controlled rotary indexing means includes output shaft 1, output shaft front end is provided with the flange for clamping workpiece or fixture, and output shaft is driven by drive mechanism 3 by numerical-control motor 2；Being also equipped with detecting the encoder 4 of output shaft swing offset on described output shaft, the signal output part of encoder is connected to control unit 5, and the control signal outfan of control unit 5 is connected to numerical-control motor drive circuit 6, is controlled numerical-control motor.Output shaft 1 back segment is arranged in a cabinet 7 by bearing, and encoder 4 also is located in cabinet.Control unit 5 includes PLC module or one-chip computer module or motion controller.
Embodiment as shown in Figure 1, drive mechanism 3 is Worm and worm-wheel gearing, and the worm gear of Worm and worm-wheel gearing is arranged on output shaft 1 and is positioned at cabinet 7.
Embodiment as shown in Figure 2, drive mechanism 3 is synchronous belt drive mechanism.
During utility model works, drive output shaft to carry out indexing by numerical-control motor and drive mechanism and rotate, when the infomation detection of encoder reaches required Angle Indexing, control unit output stop signal, control numerical-control motor stall, complete indexing action.If output shaft rotates over indexing position, it is also possible to be modified rotating by controlling single control numerical-control motor.
