摘要:
A clamping device for clamping two parts which more particularly serves for fixing a workpiece palette on a workpiece table. A bolster provided with a projecting shape element is secured to the first part and a cooperating part provided with a recess for receiving the shape element is secured to the second part. A sliding element which runs through the projecting shape element has at least one peripheral recess, into which at least one clamping element is engaged. The clamping element can be moved in a through hole in the shape element and fits in a non-clamping position, and on sliding the sliding element the clamping element is thrust outward into the clamping position. In the clamping position the clamping element interlocks in a recess in the cooperating part.

A cutting machine having a workpiece changer possessing a receiving element for the workpieces and/or workpiece palettes, said receiving element pivots about a vertical axis and is linearly shiftable in a plane normal to such axis. A tool spindle moves on two parallel side walls which are divided by a transverse wall or by door which can opened or shut between a front machining area and a rear supply area. The radius of the receiving element extends at least partly into a supply area and the tool spindle is movable over the front machining area. Accordingly a person minding or controlling the functioning cutting machine is not hampered by workpiece changing.

A workpiece changer for transfer of workpiece palettes between a storage arrangement arranged in front of a machining machine for such workpiece palettes and a workpiece table, possesses a gripper device for receiving and putting down workpiece palettes and a rotary drive for swiveling the gripper device about a vertical axis. A linear drive serves to shift the gripper means between a first position on the storage arrangement and a second position on the workpiece table. The storage arrangement possesses at least one change station for the transfer and acceptance of workpiece palettes by the gripper device, a conveyor apparatus being provided for the supply and removal of workpiece receiving station to and from the change station. Accordingly, satisfactory access is provided to the workpiece table during machining and workpiece changing operations may be performed at a high speed on any desired machining machines.

The invention concerns a work carrier changeover device for machine tools, with a work carrier transfer device for moving the work carrier (16) between a machining station (15) and a tooling station (21). The work carrier transfer device has a coupling element (25) rotatable around a vertical axis and two opposing coupling points (26, 27) for the coupling of work carriers (16). The coupling element (25) is pivotably mounted at free end section of a swivel arm (24) capable of swivelling around a vertical axis.

A workpiece changer for shifting workpieces or workpiece palettes between a set-up station arranged in front of a machining machine and a workpiece table has a gripper means for accepting and depositing workpiece or workpiece palettes, there being a rotary drive for pivoting the gripper means about a vertical axis and a lifting means for lifting and lowering the gripper means. A linear drive serves for transferring the gripper means between a first position at the set-up station and a second position at the workpiece table. Accordingly while ensuring satisfactory access to the workpiece table during machining extremely high speed workpiece changing operations may be performed at any desired machining machine.
摘要:
A workpiece holding means for machine tools and more particularly for milling and/or drilling machines, comprising a pivoting bridge supported between two bearing walls. The bearing walls respectively laterally delimit a working area. At least one drive motor serves for pivoting the pivoting bridge, such motor being arranged outside the working area on at least one outer side of the bearing walls. The pivoting bridge is provided with a gear ring adjacent to one or both of the inner sides of the bearing walls, such gear ring being drivingly connected with the drive gear wheel driven by at least one drive motor. The bearing points or bearing pins of the pivoting bridge accordingly do not have to transmit any drive torque and are not subjected to any torque load so that more precise running and more precise positioning is possible.

A rotary drive adapted to perform a speed of rotation switching of a tool holding device, comprising an output drive shaft bearing the tool holding device, said output drive shaft being able to be moved into first and second axial positions by means of a setting drive. The output drive shaft is coupled in the first axial position with a power driven first drive gear wheel and in the second axial position with a concentric tubular shaft, which is adapted to be driven by a power driven second drive gear wheel by way of a worm drive.
摘要:
A machining center that includes a swivel bridge supported by a bearing wall and pivotable about a horizontal axis, at least one drive sprocket attached to a disc-type connector of the swivel bridge, and at least one drive system attached adjacent the bearing wall and operatively connected to the drive sprocket of the swivel bridge. The machining center is characterized by clamping of the swivel bridge being performed by a friction-locked clamping system which is arranged rotationally fixed about a bearing pin of the swivel bridge in a circular ring shape and which is operatively connected to the disc-type connector. A clamping force of the friction-locked clamping system is generated by an energy storage.
摘要:
A cutting machine comprises a workpiece changer possessing a receiving element for the workpieces and/or workpiece palettes, said receiving element being able to be pivoted about a vertical axis and to be linearly shifted in a plane normal to such axis. At least one slide arrangement is able to be power driven in the two horizontal directions for a tool spindle and is adapted to run on two parallel side walls of the cutting machine designed in the form of a gantry machine. The intermediate space between the side walls is divided by a transverse wall or by door, which during workpiece machining is closed and during the workpiece changing operation is at least partly open, into a front machining area and a rear supply area, the radius of pivoting of the receiving element, engaging a workpiece or a workpiece palette, extending at least partly into a supply area. Accordingly a person minding or controlling the functioning cutting machine is not hampered by workpiece changing.
