Claims

[Claims for Utility Model Registration] (1) A machine tool in which a tool gripping part that grips a tool is held movable relative to a workpiece that is fixedly supported on a table in the X direction and the Y direction perpendicular to the workpiece. A positioning block that is used when machining a workpiece and is attached to a predetermined position of the workpiece to determine the reference position of the tool gripping part in the X and Y directions with respect to the workpiece, an engaging part with which a corner part of the workpiece is engaged. and a circular hole portion whose upper end is opened on the upper surface of the block body and whose axis coincides with the apex of the corner portion of the workpiece when the workpiece is engaged with the engaging portion;
1. A positioning block used for workpiece machining, comprising fixed support means for fixing and supporting the block body to the workpiece. (2) a vertical engagement surface in which the engagement portion is in close contact with one side of the corner portion of the workpiece; and a vertical engagement pin that abuts on the other side of the corner portion of the workpiece;
2. The positioning block for use in processing a workpiece according to claim 1, further comprising a horizontal engagement surface in close contact with an upper surface at a corner portion of the workpiece. (3) Claim 1 characterized in that the inner circumferential surface of the circular hole portion is a conical surface whose diameter increases upwardly.
Positioning block used for machining the work described.
