A fixing device for bending processing of a shaft-shaped member, comprising:
- a sliding rail (100) disposed in a direction perpendicular to an axial direction of a workpiece (1) having a shaft shape;
- a panel support member (110) disposed on an upper side of the sliding rail (100) to be slidable in a longitudinal direction of the sliding rail (100);
- a fixed panel (200) including a pair of plate-shaped members fixedly disposed on one side of the panel support member (110) in the longitudinal direction of the sliding rail (100) to be spaced a certain interval apart in the axial direction of the workpiece (1), and a first opening (201) formed so that an edge facing a tilting panel (300) is recessed to form a semicircle;
- a tilting shaft (111) mounted parallel to the axial direction of the workpiece (1) at a center of the panel support member (110);
- the tilting panel (300) including a pair of plate-shaped members disposed on the other side of the panel support member (110) in the longitudinal direction of the sliding rail (100) to be spaced a predetermined interval apart in the axial direction of the workpiece (1), including a second opening (301) formed to be recessed in a semicircular shape in which an edge facing the fixed panel (200) is symmetrical to the first opening (201), and having a lower end toward the second opening (301) connected to be tiltable around the tilting shaft (111);
- a rotary plate (400) having a circular disk shape formed by detachably coupling first and second rotary plates (401 and 402) of a semicircular cross-sectional shape to each other to be inserted to be rotatable in the axial direction of the workpiece (1) inside the circular openings formed by the first and second openings (201, 301), having a driven gear (410) formed on an outer peripheral surface thereof, and having a clamp (420) formed to fix an outer peripheral surface of the workpiece (1) to a semicircular central edge of each of the first and second rotary plates (401 and 402);
- a drive gear (430) configured to engage with the driven gear (410) on the outer peripheral surface of the rotary plate (400);
- a first actuator (501) configured to provide a rotational driving force to the drive gear (430) to rotate the workpiece (1) fixed to the rotary plate (400) and the clamp (420);
- a second actuator (502) mounted on the tilting panel (300) and configured to tilt the tilting panel (300) around the tilting shaft (111) to open or close a boundary portion between the first and second openings (201 and 301);
- and
- a third actuator (503) mounted at an end of the panel support member (110) and configured to cause the panel support member (110) to slide in the longitudinal direction of the sliding rail (100).
