Abstract
The utility model relates to a double-swing milling head driven by AC permanent-magnet synchronous external-rotor torque motors, belonging to the technical field of the design and the manufacturing of the double-swing milling head driven by the AC permanent-magnet synchronous external-rotor torque motors. The double-swing milling head consists of an upper unit and a lower unit. The upper unit is provided with the AC permanent-magnet synchronous external-rotor torque motors. A left AC permanent-magnet synchronous external-rotor torque motor is arranged at the left end in the A-axis direction of a cross hollow shaft and a right AC permanent-magnet synchronous external-rotor torque motor is arranged at the right end in the A-axis direction of the cross hollow shaft. Since an intermediate transmission link arranged in the scheme of using a traditional servo motor to drive a turntable is omitted, the rotational inertia, the elastic deformation, the backlash, the motion lag, the friction, the vibration, the noise and the wear caused at the intermediate link are eliminated. The utility model has the advantages of compact structure, simple transmission structure, high rigidity, less mechanism parts, high response sensitivity, no wear and no backlash. The double-swing milling head can be used for accurately machining pentahedrons. Moreover, the utility model solves all kinds of problems existing in the traditional mechanical transmission structure.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of the double-pendulum milling head that is driven by AC permanent-magnet synchronous external rotor torque motor.
Background technology
The traditional mechanical type transmission scheme of double-pendulum milling head is that power source is realized by transmission mechanism.Power source adopts servomotor (servo-hydraulic motor), and with it as a unit independently.Middle transmission link adopts gear type transmission, rack-and-pinion transmission or worm-gear type transmission.Although in this traditional scheme, be electrically connected and lack, the cost of entire product is lower, and problem is; Machining accuracy for gear, tooth bar or worm gear is had relatively high expectations usually; And, make the precision and the stability decreases of double-pendulum milling head system in the course of time because the existence of middle transmission link has produced rotary inertia, elastic deformation, backlass, motion delay, friction, vibration, noise and wearing and tearing.In addition, this is added to eliminating the mechanical facility that drive gap is taked with regard to the complicated mechanical drive mechanism, makes transmission mechanism complicated more.Because by the existence of drive gap, make its positioning accuracy can be very not high, do not satisfy the more requirement of high manufacturing accuracy.In addition, the torque motor of available technology adopting internal rotor.The torque motor of inner rotor core and outer-rotor structure is compared, and under the condition of equal volume, the moment of torsion that the torque motor of inner-rotor-type produces is less.From magnetic line of force characteristic, the rotation of inner rotor balance is poor; In addition because rotor is interior, stator outside, the diameter of rotor is less, the brake structure design is comparatively complicated, and identical brake weight acts on the less plane, braking effect is not obvious.Although selected for use hydraulic jack to clamp double-pendulum milling head, the structure that designs in order to eliminate drive gap to guarantee transmission accuracy is complicated more, and these double-pendulum milling heads do not have the automated exchanged cutter function yet, and these structures can not satisfy the requirement of numerical control of machine toolsization.
Summary of the invention
At the problems referred to above, the purpose of this utility model is the double-pendulum milling head with automated exchanged cutter function that provides a kind of fine high accuracy, AC permanent-magnet synchronous external rotor torque motor efficient, simple in structure directly to drive for machinery manufacturing industry, traditional driving, drive mechanism have been replaced with the built-in type torque motor, solving in the prior art problems such as inertia, elastic deformation, backlass, motion delay, friction, vibration, noise and wearing and tearing that rotate owing to existing of intermediate link, thereby the running accuracy and the balance of double-pendulum milling head have been improved.
Structure of the present utility model is as shown in drawings: be made of upper and lower Unit two.Last unit has the AC permanent-magnet synchronous external rotor torque motor.Having ready-packaged joint on the rotor of this motor.In the lower end of last ready-packaged joint ready-packaged joint is once arranged.Lower end at AC permanent-magnet synchronous external rotor torque motor rotor has sensing unit.Lower unit is made of shell and movement.One cross hollow shaft is arranged in the enclosure.In cross hollow shaft hollow, an electric main shaft is arranged.At the axial left end of cross hollow shaft A one left AC permanent-magnet synchronous external rotor torque motor is arranged.At the axial right-hand member of cross hollow shaft A one right AC permanent-magnet synchronous external rotor torque motor is arranged.Have left motor fixed cover in the outside of lower unit left end outer rotor torque motor.Have right motor fixed cover in the outside of right-hand member outer rotor torque motor.Left and right torque motor fixed cover connects firmly on following ready-packaged joint.
Pass through technique scheme, the present invention has omitted the middle transmission link that is provided with in the scheme of traditional driven by servomotor turntable by the double-pendulum milling head that the AC permanent-magnet synchronous external rotor torque motor drives, thereby eliminate rotary inertia, elastic deformation, backlass, motion delay, friction, vibration, noise and wearing and tearing that intermediate link produces, therefore improve the running accuracy and the stationarity of double-pendulum milling head.The utility model adopts outer rotor torque motor directly to drive double-pendulum milling head, has compact conformation, simple, the good rigidly of drive mechanism, and mechanism's parts are less, reaction sensitivity is high, nothing is worn and torn, the characteristics of no backlass.Pentahedron processing can be carried out accurately, especially gantry Machining Center can be widely used in the high-grade, digitally controlled machine tools.
