Document Type and Number:
Japanese Patent JP2021098580
Kind Code:
A
Abstract:
To provide a positioning structure which enables even an unskilled person to carry out highly accurate positioning.SOLUTION: The position and the angle of an article 2 fixed on a pedestal 1 are changed from a temporarily placed state to a fixed state. A largest surface among a plurality of pedestal abutment surfaces which are a plurality of surfaces of the pedestal 1 is set as a main pedestal abutment surface. A largest surface among a plurality of article abutment surfaces which are a plurality of surfaces of the article is set as a main article abutment surface. When the article 2 is fixed on the pedestal 1, the article 2 is slightly moved and then positioned to be fixed from the temporarily placed state where the main article abutment surface is slidably bonded to the main pedestal abutment surface. In the temporarily placed state of the article 2, a gap T is generated between the pedestal abutment surfaces and the article abutment surface opposite to each of the pedestal abutment surfaces. The article 2 is slightly moved to be fastened to the pedestal 1 in a direction for narrowing the gap T. A feed screw mechanism 4 is provided for this purpose. A stepped part 5 is provided as a positioning guide in a place orthogonal to the abutment surface.SELECTED DRAWING: Figure 1
