Claims

[Scope of Claim for Utility Model Registration] (1) A pair of locking members are provided on a slide table which is equipped with a spindle unit having a rotating tool and is movable back and forth in a direction perpendicular to the axial direction of the rotating tool,
On the other hand, a positioning member movable in the axial direction under the action of the actuator is disposed, and a plurality of engaging portions having different widths in the forward and backward directions of the slide table are formed on the positioning member, and the slide The rotary tool is configured to be positioned coaxially with respect to the first and second processing parts, respectively, when the table is moved back and forth and the respective locking members engage with the predetermined engagement parts. Positioning mechanism. (2) Utility model registration In the mechanism described in claim 1, the slide table is engaged with a first piston rod extending from one end of the cylinder, and a second piston rod extending from the other end of the cylinder. The first and second piston rods are separated from each other by a predetermined distance.
A locking member is provided, and the slide table is moved forward and backward in a direction orthogonal to the axial direction of the rotary tool under the driving action of the cylinder, so that the first and second locking members are engaged with one of the engaging portions of the positioning member. A positioning mechanism configured to position the rotary tool coaxially with respect to the first and second processing parts when abutting the rotary tool. (3) In the mechanism set forth in claim 2 of the utility model registration claim, the positioning is performed by inserting the second piston rod into the positioning member and forming an opening so that each locking member abuts on a predetermined engagement portion. mechanism.
