WORK POSITIONING METHOD IN MACHINE TOOL, AND WORK POSITIONING DEVICE

摘要

PROBLEM TO BE SOLVED: To considerably reduce the labor and shorten the time required for positioning a work by a worker.;SOLUTION: The work 2 is placed on a work table 3, and the position of the work is regulated by abutting two surfaces 2A and 2B orthogonal to each other on regulation units 3A and 3B, respectively. Next, three first positioning members 8 are disposed at the positions on which a first abutting part 6 is abutted on other two surfaces 2C and 2D. A nut 9 is moved in adjustment grooves 5A and 5B, a bolt 10 is screwed to the nut 9 via a stepped opening 15 of each first positioning member 8, and each first positioning member 8 is fixed to the work table 3. Next, a surface 12A of a second positioning member 12 is allowed to slide along a surface 7A to form an accommodation part 7 of the first positioning member 8 to accommodate a bolt 14 to a screwing groove 18 via an opening 13A. The second positioning member 12 is fixed by a holding piece 13 and the bolt 14 so as to press and hold the work 2.;COPYRIGHT: (C)2003,JPO
