The transmission device for the numerical control rotary table solves the problems that an existing transmission device for the numerical control rotary table is easily abraded, and the transmission precision is not ensured. The transmission device for the numerical control rotary table comprises a box body, a motor, a cam shaft and an output shaft. The motor is fixedly connected to the side portion of the box body, the cam shaft is parallel to a motor shaft of the motor and transversely penetrates into the box body, the motor shaft of the motor penetrates through the box body and drives the cam shaft to rotate through a transmission mechanism, the output shaft is located on the cam shaft and longitudinally penetrates into the box body, the output shaft is sleeved with an output shaft sleeve, rolling pins are evenly distributed on the output shaft sleeve in the peripheral direction, and the camshaft is provided with an integrally formed cam meshed with the rolling pins. The transmission device for the numerical control rotary table has the advantages of being good in rigidity, high in transmission precision and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of numerical control rotating platform, particularly a kind of transmission device of numerical control rotating platform.
Background technology
Numerical control rotating platform is a kind of important machine tool accessories, its lathe that is applied as provides revolution coordinate, by the 4th axle, the 5th axle, drive that turntable completes decile, decile or continuous revolution are not processed, and make client's processed complex curved surface become possibility, have expanded the range of work of lathe.In recent years, along with domestic numerical control is along with domestic numerical control lathe is to high-speed and high-efficiency, high-precision, flexibility, the fast development of environmental protection aspect, user is also more and more urgent to the demand of numerical control rotating platform.
Current most numerical control rotating platform adopts driven by servomotor turbine and worm transmission mechanism, and to reach higher calibration and positioning precision, in assembling, worm and gear meshes closelyr, and the transmission accuracy of indexing means is higher.But adopt turbine and worm mechanism also to have some problems: after operation a period of time, turbine and worm will wear and tear, occur gap, transmission accuracy is assurance not, and the indexing accuracy of whole indexing means will reduce greatly.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides that a kind of precision is high, the transmission device of the numerical control rotating platform of good rigidly.
The purpose of this utility model can realize by following technical proposal: a kind of transmission device of numerical control rotating platform, comprise casing, motor, camshaft and output shaft, described motor is connected in casing sidepiece, described camshaft parallels with the motor shaft of motor and camshaft is laterally arranged in casing, the motor shaft of described motor is through casing and drive camshaft to rotate by transmission mechanism, described output shaft is arranged in camshaft top and output shaft is longitudinally arranged in casing, it is characterized in that, on described output shaft, be arranged with output sleeve, on described output sleeve, be circumferentially evenly distributed with needle roller, described camshaft has cam integrally formed and that be meshed with needle roller.
In the transmission device of above-mentioned a kind of numerical control rotating platform, on described camshaft, there are 5 cams, and the two ends of camshaft are connected by bearing with casing contact site.
In the transmission device of above-mentioned a kind of numerical control rotating platform, on described motor shaft, be fixed with gear one, described camshaft one end is fixed with the gear two being meshed with gear one.
As another kind of situation, in the transmission device of above-mentioned a kind of numerical control rotating platform, described motor shaft directly penetrates camshaft one end and is connected mutually with this end of camshaft.Motor shaft directly drives camshaft to rotate.
Compared with prior art, the transmission device of this numerical control rotating platform, utilize the cam drive on camshaft to drive the needle roller on output sleeve to roll, thereby make output shaft rotation, its rigidity that is that is shaped cam and integrated camshaft improves greatly, and 5 cams can embrace with a plurality of needle rollers, the precision of turntable and rigidity are improved.
