Claims

[Scope of utility model registration request]

(1) A device that measures the position of a reference block for positioning a workpiece using a predetermined main position of a machine tool as the origin, and must meet the following conditions (A), (B), and (C). A reference position measuring device featuring: A dial gauge 4 that measures the position of the shank 2 inserted into the spindle hole and the reference block 3 attached to the shank 2 that positions the workpiece 1 with the spindle position as the origin.
and a reference ring 5 having a reference surface 51 that serves as the zero point of the dial gauge 4. (B) The reference ring 5 is slidably mounted on the shank 2, and the dial gauge 4 is fixedly mounted on the shank 2 at a position where its contact 41 abuts the reference surface 51 of the reference ring 5. ing. (C) The reference ring 5 is slidable on the shank 2 so as to be able to come into contact with and release from the reference surface 51 of the contactor 41.

(2) The reference ring 5 has its inner diameter surface as a reference surface ' 5
1. A reference position measuring instrument as set forth in claim (1) of the utility model registration claim. φ

(3) The reference ring 5 is characterized by being able to slide on the shank 2 in the axial direction to position the contactor 41 outside the reference rejig 5 and release the contact with the reference surface 51. A reference position measuring device according to claim (2) of the utility model registration claim.

(4) The reference ring 5 has a partial cutout 52 on its reference surface 51, and rotates on the shank 2 to position the contactor 41 outside the cutout 52 to prevent contact with the reference surface 51. The reference position measuring instrument according to claim (2) of the utility model registration claim, which is characterized in that it can be canceled.
