Abstract

PURPOSE: To apply press contact force between needles and a wire rod and surely clamp the wire rod, by providing a cam cylinder and various needles, radially compressing the cam cylinder and clamping the wire rod at three points with the chuck needles.
CONSTITUTION: When a rotary shaft 1 and a cam cylinder 2, integrally formed with the rotated in a direction A, each of the planetary needles 8 moves rolling in a direction B. Accordingly, the needles 8 make an orbital motion in a direction C around the cam cylinder 2 integrally with a cage 13. When the needle 8 makes orbital motion to reach a position of engagement to a peak 2a' on a peripheral cam surface 2a, the cam 2 is radially compressed inward, and three chuck needles 9 applied with this compression force are pressed toward an axial line position of the cam 2. Accodingly, a wire rod 6 inserted to a gap 7 is securely clamped at three points by the three chuck needles 9.
