WORKPIECE POSITIONING DEVICE POSITIONING WORKPIECE AT TWO REFERENCE SURFACES

摘要

A workpiece positioning device (1) includes a first positioning block (Bx) positioning one surface of a workpiece at a first reference surface in a first direction, two second positioning blocks (By1, By2) positioning a different surface of the workpiece at a second reference surface in a second direction, seat blocks (Bz1, Bz2, Bz3) positioning the workpiece in a third direction perpendicular to the first direction and the second direction, a push cylinder (30) pressing the workpiece in one direction toward an intersection line between the first and the second reference surface, a first unit (10) contacting with the one surface of the workpiece and correcting a posture of the workpiece before the first positioning block contacts with the workpiece, and a second unit (20) contacting with the different surface of the workpiece and correcting the posture of the workpiece before the second positioning blocks contact with the workpiece.

1. A workpiece positioning device comprising:
a first positioning block that forms a first reference surface in a first direction, and positions one surface of a workpiece at the first reference surface; two second positioning blocks that form a second reference surface in a second direction, and position a different surface of the workpiece at the second reference surface; at least one seat block that positions the workpiece in a third direction perpendicular to the first direction and the second direction; a push cylinder that presses the workpiece in one direction toward an intersection line between the first reference surface and the second reference surface; a first unit that, before the first positioning block contacts with the workpiece, contacts with the one surface of the workpiece at friction lower than that of the first positioning block, and corrects a posture of the workpiece; and a second unit that contacts, before the second positioning blocks contact with the workpiece, with the different surface of the workpiece at friction lower than that of the second positioning blocks, and corrects the posture of the workpiece.
