Claims

[Scope of utility model registration request]

A tool positioning device that positions a reference surface of a keyway of a tool shank by abutting a reference side surface of a rotation prevention member fixed at a predetermined position on the spindle side of a tool presetter, wherein the rotation prevention member is a contact that abuts and engages the keyway;
It is characterized by being composed of a main body that holds the contact and is fixed to the spindle side, and an elastic member that is housed within the main body and biases the contact to press the contact into the keyway. Tool positioning device for tool presetter.
