Abstract
A tool holder on which a nonrotational tool is mounted is mounted on a spindle of a machining center. A tool holder body of the tool holder includes a positioning pin that is inserted into the machining center and a locking mechanism. When the positioning pin is not inserted into the machining center, the locking mechanism locks the rotation of the tool holder body relative to a drive shaft. When the positioning pin is inserted into the machining center, the locking mechanism allows the rotation of the tool holder body relative to the drive shaft.
Claims1
A tool holder on which a nonrotational tool of a machining center is mounted, the tool holder comprising:
- a sleeve that is fitted to a spindle on which the tool holder is mounted;
- a drive shaft that is connected to the sleeve;
- a tool holder body that is supported to be rotatable relative to the drive shaft;
- and
- a tool holding unit which is fixed to the tool holder body and on which the nonrotational tool is mounted,
- wherein the tool holder body includes a positioning pin that is inserted into the machining center, and a locking mechanism,
- the locking mechanism locks the rotation of the tool holder body relative to the drive shaft when the positioning pin is not inserted into the machining center, and
- the locking mechanism allows the rotation of the tool holder body relative to the drive shaft when the positioning pin is inserted into the machining center.
