Claims

[Scope of utility model registration request]

In a tool attachment/detachment device for a tool presetter in which an ID element is embedded in a pull stud of a tool mounted in a spindle and a relatively large diameter read/write head is housed in the spindle, the outer diameter of the head of the pull stud and It has an inner diameter that is the same as or larger than that, and has an outer diameter that is the same as or larger than the outer diameter of the neck of the pull stud plus twice the diameter of the sphere, and that is connected to the neck of the pull stud. A clamp consisting of a reduced diameter part having a tapered hole that movably holds the sphere to be stopped, and an elongated hollow cylindrical part that is connected to the reduced diameter part through a stepped part and extends in the axial direction of the spindle. an elongated hollow cylinder fixed within the spindle to slidably support the clamping cylinder and forming a protrusion that protrudes inward at a position facing the sphere; The small diameter part has a size that allows the sphere to be pressed against the jaw, and the large diameter part on the base end side of the stepped part has a size that is twice the diameter of the sphere added to the outer diameter of the head of the pull stud. a sleeve formed of the same or larger dimensions; and a sleeve that is slidably supported by the clamping tube and holds the read/write head at a predetermined position inside the sleeve, and its distal end surface is attached to the clamping tube. a holder in contact with the stepped portion; a movable member coupled to the clamp tube and inserted therein; a pressing means connected to the movable member and reciprocating the movable member; A tool presetter tool characterized in that a spring is provided between the holder and the holder and bias the holder and the read/write head held by the holder in a direction to press the stepped portion of the clamping cylinder. Attachment and detachment device.
