Claims14
A fitting device for a removable tool holder (17) for receiving insertion tools of a machine tool (10) comprising:
- a protective sleeve (12) arranged around the tool holder (17) that forms a releasable sliding fit (18) with a drive tube (16);
- and at least one locking element (24) securing the tool holder (17);
- whereby the locking element (24) is oriented in a direction perpendicular to said sliding fit (18) so that for removing the tool holder (17) from the fitting device the protective sleeve (12) of the tool holder (17) is removed, then the at least one locking element (24) is completely removed, and then the tool holder (17) is separated from the fitting device, wherein the tool holder (17) and the drive tube (16) have bore holes (13, 14) extending in the direction perpendicular to the sliding fit (18) and aligned with one another, and the locking element (24) is inserted in the bore holes (13, 14) of the tool holder (17) and the drive tube (16).
A fitting device for a removable tool holder (17) for receiving insertion tools of a machine tool (10) comprising:
- a protective sleeve (12), a tool holder (17), a drive tube (16), four locking elements (24), and an internal ring (23) in protective sleeve (12) wherein:
- the protective sleeve (12) is arranged around the tool holder (17),
- the tool holder (17) forms a releasable sliding fit (18) with the drive tube (16),
- four bore holes (14) are located in the drive tube (16),
- four bore holes (13) are located on a circumference of the tool holder (17),
- the four locking elements (24) are cylindrical pins insertable into the bore holes (14) of drive tube (16) and the bore holes (13) of tool holder (17) securing the tool holder (17), and
- the four bore holes (13) on a circumference of the tool holder (17) are covered by the internal ring (23) of the protective sleeve (12) so that:
- for removing the machine tool holder (17) from the fitting device the protective sleeve (12) of the tool holder (17) is removed, then the four locking elements (24) are completely removed, and then the tool holder (17) is separated from the fitting device.
