Definitions

  • the present invention relates generally to a universal machine tool and more specifically to a universal machine tool having a machining unit and a workpiece slide.
  • the machining unit is movable along a plurality of axes by means of a motor and includes a motor-driven work spindle for receiving the machining tools.
  • the workpiece slide is for the workpieces that are to be machined and is movable on a machine bed by means of a motor.
  • the work spindle is carried by a swiveling milling head which is turnable about a locating face that is inclined by 45 degrees with respect to the vertical plane.
  • the milling head is located on a vertical face wall of a support housing.
  • the support housing is attached to the face of a travelling stand so as to be vertically movable.
  • the travelling stand is mounted on guiding rails in the rear end of a machine bed so as to be movable by means of a motor.
  • a table slide having a workpiece table is located so as to be horizontally movable.
  • a workpiece slide is disclosed with at least one turnable workpiece accommodation and an associated rotary drive by which the workpiece accommodation can be driven for carrying out turning operations on the workpiece to be processed.
  • the universal machine tool according to the present invention provides the possibility to carry out turning operations by means of a rotary main cutting motion by the workpiece, in addition to milling, drilling, and threading operations by means of a rotary main cutting motion by the tool.
  • an effective, automatic complete machining of workpieces of even complicated shapes may be effected without any complicated re-clamping of the workpieces between a turning and a milling or drilling machine.
  • a higher machining accuracy is obtainable.
  • Another important advantage of the machine tool of the present invention is that the travelling paths of a work spindle provided for milling and drilling may also be used for the feeding and supply motions for turning operations, whereby the complexity of the construction and control technology may be decreased. Aside from the milling technology, the turning technology may also be covered by one control with the same user interface.
  • the workpiece accommodation may, for example, be formed as a horizontal rotary spindle including workpiece clamping means.
  • the rotary spindle is, for example, borne in a spindle head integrally formed with the workpiece slide.
  • the rotary spindle may, however, also be disposed in a separate spindle head which can be mounted on a workpiece slide if required.
  • the arrangement enables a simple retrofit or detachment of the rotary spindle for possibly changing machining tasks.
  • the workpiece slide may also include a horizontal workpiece table which is turnable about a vertical axis and includes an integrated rotary drive as a workpiece accommodation.
  • a machine tool having such a workpiece slide milling and turning operations can be carried out in one clamping position even on larger or bulky workpieces.
  • the range of applications of the machine tool can be widened, and machining accuracy may be enhanced.
  • the workpiece accommodation may, for example, be driven by a ring-shaped driving motor comprising a stator ring fixed, for example, to a console of the workpiece slide and a rotor ring fixed to the turntable resulting in a particularly compact embodiment.
  • the driving motor may, for example, be a collectorless ring-shaped torque motor enabling a direct drive with high dynamics and exact positioning without an additional gearing or coupling.
  • the workpiece accommodation may, with such little spatial requirements and weight, not only be driven with high dynamics for carrying out turning operations, but may also be positioned in arbitrary angular positions to carry out, for example, special milling or drilling operations.
  • a workpiece exchanger that can be inserted into the work spindle. Since the work spindle can carry out all of the movements required for a workpiece exchange at the rotary spindle, no separate driving motors or travelling elements are necessary in this case.
  • the workpiece exchanger may, for example, be a workpiece gripper provided with a plurality of gripper arms by which the finished workpieces are transported from the rotary spindle to a workpiece deposit.
  • the rotary spindle may also be supplied with new workpieces via the workpiece gripper.
  • a rod feeding magazine may also be provided by which the turning spindle is supplied with rod-shaped material.
  • the workpiece gripper may operate via an internal coolant supply in the work spindle. This way, additional operational components may be omitted.
  • an automatically operable three or more jaw chuck may be located on the rotary spindle.
  • the rotary spindle may also have an internal clamping cone for receiving different power jaw chucks.
  • FIG. 1 is a perspective side view of a universal machine tool for milling, drilling, and turning operations according to the present invention
  • FIG. 2 is a perspective, partially cross sectional side view of the universal machine tool of FIG. 1 including a rod feeding magazine and a protective cabin;
  • FIG. 3 is a partially cross sectional perspective view of an alternative workpiece slide comprising a turntable
  • FIG. 4 is a perspective view of the workpiece slide of FIG. 3 including a clamped workpiece and turning tools for explanation of the turning operations in the universal machine tool according to the present invention.
  • the universal machine tool shown in FIG. 1 includes a machine bed 1 on which a workpiece slide 2 is disposed so as to be movable along a y-axis in the direction of the double arrow 3 by means of a motor (not shown).
  • the workpiece slide includes a spindle head 4 which bears a horizontal rotary spindle 5 which is driven by means of a driving motor (not shown).
  • the rotary spindle is provided with an automatically operable three jaw chuck 6 as a means for clamping workpieces.
  • the rotary spindle may, however, also be provided with other workpiece clamping means and/or an internal clamping cone for receiving different power jaw chucks or the like.
  • a travelling stand 9 On the rear part of the machine bed 1 are mounted guiding rails 7 and 8 on which a travelling stand 9 is guided so as to be horizontally movable along an x-axis via a motor-driven threaded spindle 10 .
  • a support housing 11 On the front side of the travelling stand is a support housing 11 that is vertically movable up and down along a z-axis in the direction of the double arrow 12 .
  • the support housing has a face wall 13 that is inclined by 45 degrees with respect to the vertical plane and extending obliquely downward.
  • a swiveling milling head 14 Mounted on the face wall is a swiveling milling head 14 including a work spindle 15 turnable by means of a motor (not shown).
  • the milling head and work spindle form a machining unit that is turnable about a swiveling axis 16 which is perpendicular to the face wall.
  • the work spindle is borne within the swiveling milling head in an angle of 45 degrees with respect to the swiveling axis.
  • the work spindle can thus be turned from a vertical machining position indicated by solid lines to a horizontal machining position indicated by broken lines.
  • a chip conveyer 17 is located for removing the chips produced during the machining process.
  • the tools for turning operations may also be inserted into the work spindle 15 .
  • the tools may be disposed in corresponding clamps or tool accommodations which are deposited in a tool magazine (not shown) and can be inserted into the work spindle by means of an appropriate tool exchanger (not shown).
  • a tool carrier for indexable inserts can be inserted into the work spindle. The rotary main cutting motion is then generated by the motor-driven rotary spindle.
  • the feeding motion along the y-axis is created by moving the workpiece slide 2 with the rotary spindle arranged thereon while the feeding motions along the x- and z-axes are created by moving the travelling stand 9 and the support housing 11 .
  • complex turning motions may be carried out with high precision by a controlled movement along the individual travelling and turning axes.
  • the common tools for milling, drilling, boring, and threading processes or the like can also be inserted into the work spindle. Therefore, all other types of machining, such as milling, drilling, boring, reaming, and threading can also be carried out on the workpieces clamped to the turning spindle before or after the turning operations. Thus, complete machining without any complicated re-clamping between different types of machines is enabled.
  • a workpiece exchanger 18 shown in FIG. 1 for exchanging the workpieces clamped to the rotary spindle 5 may also be insertable into the work spindle 15 .
  • the insertion of the workpiece exchanger into the work spindle may be performed by an automatic tool exchanger (not shown).
  • the workpiece exchanger is deposited in a tool magazine (also not shown) during the machining process.
  • the workpiece exchanger may, for example, be a workpiece gripper provided with a plurality of gripping arms 19 insertable into the work spindle via a clamping cone.
  • the gripping arms may be operated by the internal coolant supply of the work spindle in an efficient embodiment.
  • a well known rod feeding magazine 35 is located in front of the machine bed 1 .
  • rod shaped workpieces may be transported to the rotary spindle 5 formed as a hollow shaft and clamped by the three jaw chuck 6 .
  • a protective cabin 36 used to enclose the machine tool, is shown as well.
  • FIG. 3 another workpiece slide 20 is shown which can be used instead of the workpiece slide 2 illustrated in FIGS. 1 and 2.
  • This workpiece slide 20 comprises a console 21 on which a horizontal turntable 22 is borne via a ring bearing 23 so as to be rotatable about a vertical axis.
  • a driving motor 25 In a ring space 24 , vertical to the rotational axis of the turntable within the console, is located a driving motor 25 .
  • the driving motor includes an inner stator ring 26 fixedly connected to the console on the inner wall of the ring space and an outer rotor ring 27 fixed to the bottom side of the turntable.
  • a tappet 28 protruding downward.
  • the driving motor may be a collectorless ring-shaped torque motor enabling, in addition to high dynamics for carrying out turning operations, an exact positioning for carrying out milling and drilling operations in different angular positions even without a coupling or gearing.
  • Clamping by the turntable 22 of FIG. 3 or the rotary spindle 5 of FIG. 1, for carrying out a milling process on a workpiece which is not rotationally driven, may be accomplished by the motor or a separate clamping means which can be activated if required.
  • one or more flyweight sensors by which an unacceptable flyweight can be detected and by which the machine tool can be turned off, may be disposed on the turntable or the rotary spindle.
  • FIG. 4 shows an embodiment for turning operations in a machine tool according to the present invention including the workpiece slide 20 according to FIG. 3.
  • a table 31 to be machined is clamped upside down.
  • turning tools 32 , 33 , and 34 which can be inserted into the work spindle 15 shown in FIG. 1, different turning operations may be carried out with a corresponding drive of the turntable.
  • turning operations on the inner and outer side of the turntable may be carried out with the turning tools 32 and 34 , and recessing works may be effected by the turning tool 33 .
  • Many other turning operations will be known to one of ordinary skill in the art.
  • the turning spindle may, for example, be disposed in a separate spindle head which is, for example, detachably mounted on a table slide.
  • the workpiece slide may additionally comprise a rotary spindle turnable about a horizontal axis as well as a workpiece table turnable about a vertical axis.
