There is disclosed a presettable tool supporting device for machine tools which permits the tool to be preset in its tool holder away from the machine and then quickly and easily mounted on the machine in an accurately predetermined position, thus eliminating the need for adjusting the tool on the machine. The disclosed tool supporting device generally comprises a tool holder having means for affixing a tool thereto, a base member having attaching means for semi-permanently attaching the base member to a machine tool, locating means preferably in the form of complementary corrugated surfaces engageable with one another when the tool holder is placed in engagement with the base member to locate each with the other along two major axes while permitting relative movement between the two along a third major axis, stop means for locating the tool holder with respect to the base member in a predetermined position along the third axis, and releasable locking means for detachably locking the tool holder to the base member in said predetermined position. Several embodiments are disclosed, including one in which the locking means is accessible from the side and another in which access is from the top, and a further one in which locating and locking is accomplished on a second set of axes in addition to the first set. Alternative stop means and locking means are also disclosed. |
