。Conventionally, a chuck device for holding a ring-shaped member in a skewer-like manner has a chuck body (1) as shown in FIGS. 3 and 4.
Linear guide holes (
2), a ball (4) biased by a spring (3) is movably inserted into the guide hole (2), and the ball (4) is chucked at the open end of the guide hole (2). Main body (1
) A stopper ring (5) having an inner diameter slightly smaller than the diameter of the ball (4) that can be fitted and locked in a slightly protruding manner is fitted onto the outer periphery of the chuck part (1a) of the ball (4) to make the ball (4) elastic. The chuck body (1)
The chuck part (1a) of the ring-shaped member (6) is inserted into the through hole (
When inserted into the guide hole (2), the ball (4), which comes into pressure contact with the stopper ring (5) and slightly protrudes from the outer periphery of the chuck part (1a) of the chuck body (1), resists the spring (3) and slides into the guide hole (2). ) is pressed against the circumferential surface of the through hole (6a) of the ring-shaped member (6) while moving backward in the direction opposite to the opening side. ) is held in the chuck body (1) in a skewered state by the ball (4).

持姿勢が正常であるか否かを検出する。The chuck device (1)) includes a cylindrical chuck body (13) to which a cylinder rod (12) is attached, and pins (15) installed in several notched grooves (14) at the tip of the chuck body (13). A plurality of chuck jaws (16) are pivotally connected to each other so that they can be expanded/contracted/closed via There is a chuck jaw operating shaft (
17) is composed of a chuck claw operating spring (18) that always presses the chuck jaw downward. The chuck main body (13) has a holding part (13a) at the lower end into which the through hole (19a) of the ring-shaped member (19) can be inserted, and the holding surface of the chuck claw (16) is formed from the outer periphery of this holding part (13a). (16a) is made to protrude slightly. The chuck jaw operating shaft (17) has a spherical part (17a) formed at the lower end, and this spherical part (17a) is pressed against a tapered surface (16b) provided on the chuck jaw (16) to remove the chuck jaw (16). Hold it extended towards the side. The chuck claw (16) forms a stopper part (16c) at the upper end,
By abutting a part of this stopper (16c) against the ceiling surface (14a) of the notched groove (14), the chuck claw (16)
expansion is regulated. In addition, (20) is the chuck body (1
3), one end of which is connected to the holding part (13a).
), and the other end communicates with an air pressure feeding passage (21) formed in a cylinder rod (12) connected to an air pressure feeding device such as a compressor.
) After the ring-shaped member (19) is held in the holding part (13a) of the ring-shaped member (19), air is fed under pressure and pressure fluctuations due to air leakage are detected by an appropriate means, thereby changing the holding position of the ring-shaped member (19). Detect whether it is normal or not.

) The ring-shaped part t has a different inner diameter by changing the shape of
It (19) can be held and also a small diameter ring-shaped member (19) can be held. Further, in the chuck device (1)), each chuck claw (16) that presses against the circumferential surface of the through hole (19a) of the ring-shaped member (19) sequentially moves (therefore, the ring-shaped member (19) ) has an automatic centering function that holds the chuck concentrically with respect to the chuck body (13).Furthermore, in the chuck device W(1)) e5, the chuck can be made larger. The holding part (13) of the chuck body (13)
There is a large gap between a) and the ring-shaped member (19), and this gap allows the ring-shaped member (19) to move relative to the chuck body (13). Even if there is misalignment between the mounting hole to be press-fitted and the chuck body (13), this can be absorbed.
