Definitions

  • the invention relates to a tool drive for machine tools with a work spindle for receiving a tool head with a machine-mounted spindle motor for the rotary drive of the work spindle, with at least one electric motor arrangement for the actuator of an adjusting device arranged in the tool head.
  • the object of the invention is to develop a tool drive which enables a modular structure and simple retrofitting in existing machine tools and which also enables the use of relatively simple tool heads of small size.
  • the combinations of features specified in claims 1, 14 and 19 are proposed.
  • Advantageous refinements and developments of the invention result from the dependent claims.
  • the solution according to the invention is based on the idea that with an arrangement of the motor arrangement for the actuator in the work spindle, an inevitable synchronization of the spindle rotation with the rotation of the actuator in its rest position takes place, so that the positioning of the actuators via the actuator is facilitated.
  • the at least one motor arrangement is arranged in the work spindle and can be coupled via an output shaft to a rotary connection arranged on the tool head for the adjusting device.
  • the output shaft of the motor arrangement is arranged coaxially to the spindle axis, while the rotary drive for the adjusting device is arranged coaxially on the tool head.
  • a modified embodiment variant with several adjustment devices provides that at least two motor arrangements are arranged in the work spindle, which can be coupled to the associated adjustment device by means of output shafts concentric or eccentric to the spindle axis, each with a rotary drive arranged concentrically or correspondingly eccentrically on the tool head.
  • the eccentric output shafts are expediently arranged at equal angular distances from one another in the work spindle.
  • the power supply device expediently has an inductive transmission path with a machine-side primary coil and a spindle-side secondary coil.
  • the power supply device may also have a galvanic transmission path with mechanical includes sliding contacts on the side and slip rings on the spindle side. If at least two motor arrangements are provided, a power supply device with a common inductive or galvanic transmission path can be provided for this.
  • a preferred embodiment of the invention provides that the at least one motor arrangement has a stator arranged fixed to the spindle and a rotor coupled to the output shaft, the rotor being able to be rotatable coaxially or eccentrically to the axis of rotation of the work spindle and the output shaft being rigid or via an intermediate gear is connected to the rotor.
  • the motor arrangement and the secondary-side part of the power supply are arranged in a slide-in cassette for releasable use in the work spindle.
  • the motor arrangement can be arranged anywhere along the work spindle or the spindle cassette.
  • the motor arrangement is advantageously arranged together with the part of the power supply device on the secondary side at the end of the work spindle or the spindle cassette opposite the tool holder.
  • the machine-mounted spindle motor is expediently coupled to the work spindle via gear means, for example a toothed belt drive, a chain drive or a gear drive.
  • gear means for example a toothed belt drive, a chain drive or a gear drive.
  • the work spindle can be designed as a directly driven spindle rotor of a motor spindle, the spindle rotor forming the stator of the at least one electrical motor arrangement and the spindle rotor containing the at least one motor arrangement being incorporated in the delstator of the work spindle insertable cartridge can be formed.
  • the power supply device can comprise a galvanic or a wireless, in particular inductive, data transmission path for the control of the at least one motor arrangement in all the embodiment variants, wherein control electronics connected to the secondary side of the power supply device and the data transmission path can be arranged for the control of the at least one motor arrangement ,
  • the arrangement according to the invention allows the spindle rotor to contain at least two separate channels which can be connected to the tool head and which can be acted upon by air or various coolants and / or lubricants from the machine side via an at least two-channel rotary distributor.
  • the tool drive according to the invention is advantageously used for rotating and actuating facing heads or boring heads.
  • the tool drive according to the invention can be used to control an angle drive, in particular for an angle drilling head.
  • the rotary drive according to the invention has the advantage in facing slide valves that accuracy problems, such as can occur in linear actuators due to the heat of the connecting rod, are avoided. A further improvement in accuracy is achieved due to the motor arrangement integrated in the work spindle in that there is a closed power flow within the drive system.
