Claims

[Scope of utility model registration request]

A tool positioning device that positions a tool shank by fitting a key groove of a tool shank into a rotation prevention member disposed at a predetermined position on the spindle side of a tool presetter, wherein the rotation prevention member is positioned simultaneously on both sides of the key groove. a contact having a contact portion formed on the distal end side with a slope on at least one surface for abutting engagement; a guide portion slidably supporting the contact;
A tool positioning device for a tool presetter, comprising an elastic member housed in the guide portion and urging the contactor to press the contactor into the keyway.
