Claims

[Scope of utility model registration request]

It consists of a main body part and a collet part which is integrally formed with the front end part of the main body part so as to be able to move out and retract from the machining hole of the workpiece, and which has elasticity in the radial direction, and communicates with the internal space of the collet part. a depth check member having a through hole passing through the depth check member, a support member that supports the main body of the depth check member so as to be movable in the axial direction of the machined hole, a drive mechanism that moves the support member, and the depth check member. a first spring interposed between the main body and the support member to bias the depth check member in the direction toward the machined hole; a first spring inserted into the through hole of the depth check member and moved in the axial direction of the machined hole; A hole diameter check rod freely supported by the support member, a second spring interposed between the hole diameter check rod and the support member to bias the hole diameter check rod in a direction toward the machined hole, and the collet. a tapered surface that is formed on at least one of the inner circumferential surface of the collet portion and the front end portion of the hole diameter check rod that are in sliding contact with each other, and whose diameter gradually decreases toward the distal end surface of the collet portion; and relative movement between the depth check member and the support member. and a hole diameter measuring means that detects the relative movement between the depth check member and the hole diameter check rod to measure the diameter of the machined hole. This is a machined hole depth and hole diameter measuring device.
