HOLLOW GUIDE SHAFT BODY UNIT, AIR SPINNING DEVICE, SPINNING MACHINE, AND ASSEMBLY METHOD OF HOLLOW GUIDE SHAFT BODY UNIT

摘要

PROBLEM TO BE SOLVED: To provide a hollow guide shaft body unit in which a hollow guide shaft body and a guide pipe are precisely assembled on a predetermined line, an air spinning device, a spinning machine, and an assembly method of the hollow guide shaft body unit.;SOLUTION: A hollow guide shaft body unit 100 comprises: a first holder 130 on which a first screw part 135 whose center line is a line L is disposed; a hollow guide shaft body 110 and a guide pipe 120, which are supported by the first holder 130 so as to be positioned on the line L; and a second holder 140 on which a second screw part 143 that screws together with the first screw part 135 is disposed. A first curve surface 136a whose center line is the line L is disposed on the first holder 130. A second curve surface 144a that faces the first curve surface 136a is disposed on the second holder 140. A clearance between the first curve surface 136a and the second curve surface 144a is narrower than that between the first screw part 135 and the second screw part 143.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
