Embodiment Construction

[0029] figure 1 Shown is a changing device 15 according to the invention, which is configured to automatically change or exchange knives 16 ( Figure 5 to Figure 8 ). In this embodiment, the changing device 15 is configured to insert or remove a different tool 16 into or out of a spindle holding fixture 17 of a machine spindle 18 of the machine tool. For example, the tool 16 to be inserted can be removed from a storage location 19 of a tool magazine, not shown, and can be inserted into the spindle holding fixture 17 of the machine tool spindle 18 . will subsequently be based on Figure 5 to Figure 8 Describe the process.

[0030] In the described embodiment, the changing device 15 is configured for automatic changing of the knives 16 . Alternatively or additionally, the changing device 15 can also be configured for changing workpieces.

[0031] In this embodiment, the changing device 15 has a holding device 20 with at least one and according to the example exactly two hol...

Abstract

The invention relates to a change device for changing of tools and / or workpieces and provides a change device for changing or exchanging of tools and / or workpieces. The change device has a gripper device with at least one gripper arm that extends away from a rotation support body that is rotatably supported about the rotation axis and that has a holder for respectively one tool or one workpiece atits free end. By means of a rotary power train with a rotary drive motor and a rotary drive transmission, the gripper device can be rotated about the rotation axis. Particularly the rotary drive transmission has a belt gear. A first rotary position sensor is directly or indirectly coupled with the rotation support body and / or transmission output of the rotary drive transmission without interconnection of the rotary drive transmission for detection of the rotary position of the gripper device about the rotation axis.

Description

technical field [0001] The invention relates to a changing device configured to change tools and / or workpieces. The changing device is configured for use with machine tools with automatic tool change or workpiece change and can be integrated in the machine tool or can be arranged as a separate unit at or near the machine tool. Background technique [0002] Such replacement devices are known, for example, from EP 1 525 945 B1 or EP 1 013 373 B1. The changing device comprises a clamping device with two holders for the tool to be changed. The gripper unit is arranged on a shaft extending along the axis of rotation. By means of a rotary drive, the shaft can be moved about the axis of rotation. Thus, the clamping device is rotatably supported about the axis of rotation together with the shaft. [0003] Such a changing device must be able to perform tool or workpiece changes very quickly. Therefore, a high rotational acceleration or rotational speed is necessary. On the othe...
