Description
Technical field
The utility model relates to a kind of numerical control rotating platform, refers to a kind of composite rotors numerical control rotating platform especially.
Background technology
Numerical control rotating platform is as one of the main function components of machining center, for the 4th axle or the 5th axle of Digit Control Machine Tool, because its precision and performance directly affect precision and the performance of lathe entirety, normal require to have high positioning precision, the rotating torque of super large and less volume.Traditional numerical control rotating platform mainly contains two kinds of structures, and one is that servomotor connects high accurate speed reducer, and this kind of structure, volume is little, Driving Torque is large, but positioning precision is lower.Two is adopt direct driving motor, its structure as shown in Figure 1, comprise stator casing 11 and the rotor 12 being arranged in stator casing 11, stator casing 11 one end has cannelure 111 around axle, be arranged with stator coil 15, permanent magnet 17 and magnetism gathering rings 16 in cannelure 111 successively, stator coil 15 is fixed on stator casing 11, and permanent magnet 17 is fixed on magnetism gathering rings 16, rotor 12 is fixed in magnetism gathering rings 16 one end, is provided with crossed roller bearing 13 between rotor 12 and stator casing 11.This kind of direct-drive type turntable, rotor 12 end face is directly as table top, permanent magnet 17 is driven to drive transmission by stator coil 15, its structure is simple, carry encoder, positioning precision is high, but due to the restriction of axial installing space, turntable height is lower, and then make stator coil 15, permanent magnet 17 can the rotating torque of installation volume and turntable all less, for making turntable have larger rotating torque, turntable height needs higher usually, namely the direct-drive type turntable under this kind of structure, less volume and larger rotating torque can not get both.
Summary of the invention
The purpose of this utility model is to provide a kind of composite rotors numerical control rotating platform.
For realizing the purpose of this utility model, now describe its technical scheme in detail: a kind of composite rotors numerical control rotating platform, comprise stator casing and rotor, rotor comprise rotating shaft and by rotating shaft one end circumferentially radially outward along stretching the rotating disk formed, rotating shaft is arranged in stator casing, crossed roller bearing is arranged with between rotating shaft and stator casing, in crossed roller bearing, outer shroud respectively with rotating shaft, stator casing compact siro spinning technology, rotating disk is positioned on stator casing, stator casing has groove ring towards the end of rotating disk around axle, the magnetism gathering rings that one end is fixedly connected with rotating disk is arranged with in groove ring, in groove ring in magnetism gathering rings, outside is respectively equipped with the inner ring permanent magnet and outer circle of permanent magnets that are all fixedly connected with it, the inner side of inner ring permanent magnet and the outside of outer circle of permanent magnets are respectively equipped with stator interior loop and stator exterior loop, stator interior loop and stator exterior loop are individually fixed in groove ring, outer wall.
The utility model composite rotors numerical control rotating platform, magnetism gathering rings both sides install stator interior loop and inner ring permanent magnet, stator exterior loop and outer circle of permanent magnets respectively, when stator interior loop and the energising of stator exterior loop, drive the inner ring permanent magnet be fixed on same magnetism gathering rings and outer circle of permanent magnets respectively, and then acting in conjunction is in rotor, that compares that tradition only has single stator coil and a permanent magnet directly drives numerical control rotating platform, and when structure height is identical, its exportable maximum rotation torque increasing is twice.The stators and rotators establishing two covers concentric in this composite rotors numerical control rotating platform another, although its radial width can be caused to become large, be mostly a kind of flat structure owing to counting by turntable, radial extension has larger space, can't affect it and install.Therefore, the utility model composite rotors numerical control rotating platform, not only structure is simple, and positioning precision is high, and when small volume, still exportable larger rotational torque.
