Abstract
In order to use moved masses which are as small as possible in a machine tool, in particular for the rotary machining of workpieces, comprising a machine frame, a tool carrier, a workpiece carrier, it is proposed to provide a parallel kinematic arrangement, which has three parallelogram guides connected in an articulated manner at one end to a receiving means for one of the carriers and at the other end to a slide and an N/C-controlled linear drive for each slide and by which the carrier arranged on the receiving means is movable relative to the machine frame in a three-dimensional movement space.
Claims29
A machine tool, for the rotary machining of workpieces, comprising:
- a machine frame,
- a workpiece carriers,
- a tool carrier arranged on the machine frame below said workpiece carrier, the tool carrier being adapted to be equipped with a plurality of tools, the plurality of tools being arranged in a two-dimensional pattern, each tool being spaced from the tool next to it, the two-dimensional pattern being adapted to provide at least one aperture in the tool carrier for the removal of chips which drop down,
- a parallel kinematic arrangement, which has three parallelogram guides each being connected in an articulated manner at one end to a receiving means for the workpiece carrier and at the other end to a slide, and
- an N/C-controlled linear drive for each of said slides, said N/C controlled linear drives enabling movement of the workpiece carrier arranged on the receiving means relative to the tool carrier arranged on the machine frame in a three-dimensional movement space.
A machine tool for the machining of workpieces, comprising:
- a machine frame,
- a tool carrier,
- a workpiece carrier,
- a parallel kinematic arrangement, which has three parallelogram guides each being connected in an articulated manner at one end to a receiving means for one of the workpiece carrier and tool carrier and at the other end to a slide,
- an N/C-controlled linear drive for each of said slides, said N/C controlled linear drives enabling movement of the carrier arranged on the receiving means relative to the machine frame in a three-dimensional movement space, and
- said machine frame comprising a base body adapted to be placed on a setting area and supports for the linear drives projecting from the base body on a side remote from said setting area.
A machine tool for the machining of workpieces, comprising:
- a machine frame having a base body,
- a tool carrier,
- a workpiece carrier,
- a parallel kinematic arrangement, which has three parallelogram guides each being connected in an articulated manner at one end to a receiving means for one of the workpiece carrier and tool carrier and at the other end to a slide, and
- an N/C-controlled linear drive for each of said slides, the respective linear drive being protected by a dimensionally rigid covering which is moved jointly with the respective slide in a rigid manner, the covering extending at least from the slide as far as the base body in all positions of the slide, and the covering being adapted to enter a covering-receiving means provided in the base body of the machine frame, said N/C controlled linear drives enabling movement of the carrier arranged on the receiving means relative to the machine frame in a three-dimensional movement space.
A machine tool for the machining of workpieces, comprising
- a machine frame having a base body,
- a tool carrier,
- a workpiece carrier,
- a parallel kinematic arrangement, which has three parallelogram guides each being connected in an articulated manner at one end to a receiving means for one of the workpiece carrier and tool carrier and at the other end to a slide, and
- an N/C-controlled linear drive for each of said slides, said N/C controlled linear drives enabling movement of the carrier arranged on the receiving means relative to the machine frame in a three-dimensional movement space
- a line train to the receiving means movable by the parallel kinematic arrangement,
- a line train protection moveable with respect to the carrier held on the receiving means and the machine frame, the line train protection comprising a tube which is mounted in a pivot bearing arranged on the machine frame on a side of the said carrier opposite to the base body, the tube being extendable in its longitudinal direction.
