Abstract
A tool holder (1) includes a clamping member (4) for clamping and holding a tool (5), a holder body (2) having, at a leading end thereof, a receiving portion (25) for receiving the clamping member (4) along an axis (AX) and an operational member (N) for attaching the clamping member (4) to the holder body (2). The clamping member (4) clamps the tool (5) by an operation of the operational member (N). Vibration is applied to a contact portion (T) between the clamping member (4) and the holder body (2) when the clamping member (4) clamps the tool (5).
Claims14
A tool clamping method for a tool holder, the tool holder comprising:
- a clamping member for clamping and holding a tool;
- a holder body having, at a leading end thereof, a receiving portion for receiving the clamping member along an axis;
- and
- an operational member for attaching the clamping member to the holder body;
- said method comprising the steps of
- inserting the tool into the clamping member,
- axially pressing the clamping member into clamping engagement with the holder body by activating the operational member,
- when the clamping member clamps the tool during the clamping operation, applying vibration to a contact portion between the clamping member and the holder body as the clamping member is axially pressed into engagement with the clamping tool, to axially align the clamping member with the holder body, and
- ceasing vibration application when the clamping is completed.
A tool holder comprising:
- a clamping member for holding by clamping a tool;
- a holder body having, at a leading end thereof, a receiving portion for receiving the clamping member along an axis;
- an operational member for attaching the clamping member to the holder body and clamping the tool by activating the operational member;
- and
- a vibration generator positioned for applying vibration to a contact portion between the clamping member and the holder body as the clamping member is slid into contact with the holder body to axially align the clamping member with the holder body when the clamping member clamps the tool during the clamping operation.
