  • the invention relates to a gearless, integrated spindle drive for an industrial processing machine, in particular for a numerically controlled machine tool, with a main spindle and a main spindle motor assigned to it, with a first driven pivot axis and with at least one further pivot axis for positioning the main spindle.

  • Servomotors are usually used for this.
  • a conventional design has a C-axis, which is realized by a servo motor with gear transmission, while the A-axis has another servo motor with belt transmission and downstream gear transmission.
  • the main disadvantage here is that there is a so-called “soft” point between the respective motor as an actuator and the actually driven axis, especially the machining tool rigidly coupled to the axis. This results in poor mechanical rigidity, which is undesirable is.
  • this object is achieved by an integrated spindle drive for driving and for positioning. nation of a main spindle with a first driven swivel axis and with at least one further swivel axis for positioning the main spindle, the first and the second swivel axis being directly drivable via respectively assigned high-pole permanent magnet excited synchronous motors and the respective permanent magnet excited rotor being integrated into the respective swivel axis.
  • first pivot axis is arranged perpendicular to the second pivot axis and the second pivot axis is arranged perpendicular to the main spindle.
  • the second pivot axis is integrated in the first pivot axis and is interrupted by the main spindle and is divided into two partial axes lying on a line.
  • the two partial axes are rigidly connected and coupled via the first swivel axis.
  • a multi-pole permanent magnet synchronous motor is assigned to at least one partial axis.
  • a further advantageous embodiment of the gearless, integrated spindle drive according to the invention is distinguished by a particularly simple and therefore inexpensive implementation, in that an encoder system is assigned only to the partial axis having the high-pole permanent magnet-excited synchronous motor.
  • a further advantageous embodiment of the gearless integrated spindle drive according to the invention provides for synchronization of the high-pole, permanent magnet-excited synchronous motors assigned to the two partial axes via a configuration as master and slave or parallel connection.
  • the motor with the encoder system acts as the master motor, to which the slave motor is synchronized.
  • a gantry arrangement can be selected. However, a separate measuring system is required for each partial axis.
  • Torque motors have proven to be particularly suitable as multi-pole permanent magnet synchronous motors, in particular versions with low speeds and high torque.
  • Such suitable torque motors are e.g. offered by the Swiss company ETEL (for more information, see website http://www.etel.ch/dds/tma).
  • a particularly compact design can be achieved if each rotor of a torque motor is built directly on the shaft of the corresponding swivel axis.
  • the poles or Partial poles are magnetized on the corresponding shaft to generate an excitation field, the shaft itself serves as a rotor.
  • a shrink ring with permanent magnets for generating an excitation field can be mounted on the corresponding shaft.
  • the embodiment according to the invention thus does not require a gearbox and enables greater mechanical rigidity through directly driven swivel axes. In addition, a more compact structure is made possible with the same performance.

  • the A-axis is also divided into two sub-axes AI and A2. This enables a particularly compact structure.
  • a drive attachment B is shown, which is installed, for example, permanently or can represent a slide.

  • the C axis C is rotatably connected to the drive mounting B via a bearing LG1, usually a fixed bearing, and is driven by a first torque motor Ml.
  • a torque motor is a brushless, multi-pole, permanent magnet-excited synchronous motor (for more information, see the information on the website above).
  • the C-axis is guided as a circular shaft Wl through a corresponding hole in the drive mounting B.
  • Stator of this first torque motor Ml is housed in the area of this bore around the shaft Wl in the drive mounting B.

  • the poles or partial poles can also be magnetized onto the shaft.
  • the tolerances are to be dimensioned such that an effective air gap is established between the surface of the permanent magnets and the inner surface of the stator. It goes without saying that the permanent magnets must be matched to the stator winding with regard to the desired high number of pole pairs.
  • the C axis has a U-shaped fork (ü) in the region adjacent to the shaft W1.
  • the space within this isosceles fork serves to accommodate the main spindle H with the corresponding main spindle drive HM.
  • This is usually a permanent magnet synchronous motor (1FE1) or an asynchronous motor (1PH2).
  • the main spindle H with drive HM is supported by a second swivel axis A, the A axis, in the fork above the C axis.
  • the fork U has respective bores in both legs for receiving the A axis. Due to the space required by the main spindle H with the main spindle drive HM, the A-axis is divided into two partial axes AI and A2 (closely hatched), which are however fixed to each other via a rigid connection V (closely hatched).
  • This rigid connection V also carries the main spindle drive HM with the main spindle H.
  • the main spindle and the A axis with the partial axes AI and A2 are arranged perpendicular to one another.
  • the A axis is also arranged perpendicular to the C axis.
  • each partial axis AI or A2 is arranged in the respective leg of the fork ü like the C-axis in the machine attachment B.
  • the partial axis A2 consists of a shaft, which in turn takes over the function of the rotor L2 of a torque motor M2.
  • the shaft of the partial axis in the area of the stator winding has poles or sub-poles to generate the excitation field and accordingly in turn serves as rotor L2.
  • the other partial axis AI has the same structure in the opposite leg of the fork ü.
  • the partial axis AI forms a further torque motor M3 with the stator winding there and the property as rotor L3.
  • Both partial axes AI and A2 are slidably mounted in the fork U via respective bearings LG2 and LG3.
  • At least one bearing should be designed as a fixed bearing.
  • the second bearing can then be designed as a floating bearing.
  • positions can also occur due to operational reasons that can result in strong forces on this floating bearing, it is advisable to provide fixed bearings for both bearings LG2, LG3.
  • a single torque motor is also sufficient to drive the A-axis, in which case the other partial axis is only slidably supported in the fork U.
  • the embodiment shown in FIG. 1 with two torque motors M2 and M3 is recommended in order to achieve the greatest possible torque and to be able to apply correspondingly greater forces.
  • At least one partial axis must have an encoder system G, here the partial axis A2. However, it must then be ensured that the connection of the two partial axes has sufficient rigidity. In this case, an encoder system G that is capable of supplying current, speed and position signals to a higher-level controller (not shown) is sufficient. Above all, this can be a numerical control. If these conditions are not met, separate encoder systems should be available for both partial axes A2, A3 or both torque motors M2, M3.

Abstract

L'invention concerne un dispositif d'entraînement de broche sans engrenage intégré, servant à entraîner et à positionner une broche principale avec deux arbres pivotants menés qui peuvent être entraînés directement chacun respectivement par un moteur synchrone à aimant permanent et comportant un grand nombre de pôles, qui lui est affecté, en particulier par un moteur-couple, le rotor à aimant permanent de chacun de ces moteurs étant intégré dans l'arbre pivotant correspondant. Un tel système est obtenu par enfilage sur l'arbre d'une frette pourvue d'aimants permanents ou bien par magnétisation de pôles/pôles partiels sur l'arbre.
