摘要： [Object] To link a finger support part easily and stably to a chuck main body part and to detach the finger support part safely and readily from the chuck main body part through a manual operation.
[Solution] An air chuck includes: a finger support part 2 including a pair of fingers 5; a chuck main body part 3 including an operation mechanism 6 operable to open and close the pair of fingers 5; and linking mechanisms 4 that detachably link the finger support part 2 to the chuck main body part 3. The linking mechanisms 4 each include: a linking shaft that extends from the finger support part 2; a shaft insertion hole 44 formed in a body 23 of the chuck main body part 3; a catch body 19 that becomes elastically caught on a catch surface 18a of the linking shaft when the linking shaft is inserted into the shaft insertion hole 44; and a delinking member 70 that is manually operated so as to release the catch body 19 caught on the catch surface 18a when the finger support part 2 is detached from the chuck main body part 3.

摘要： [Object] To prevent a pair of fingers that are included in a chuck unit from being freely displaced when the chuck unit is detached from an operation unit. [Solution] An air chuck 1 includes a chuck unit 2 including a pair of fingers 4a and 4b that capable of being freely opened and closed, an operation unit 3 that includes an operation mechanism 5, which opens and closes the pair of fingers 4a and 4b, connection mechanisms 6 for attaching the chuck unit 2 to the operation unit 3 such that the chuck unit 2 is freely attachable and detachable to and from the operating unit 3, and a locking mechanism 7 that locks the pair of fingers 4a and 4b such that the pair of fingers 4a and 4b are capable of being freely opened and closed when the chuck unit 2 is attached to the operation unit 3 and such that the pair of fingers 4a and 4b are not able to be opened or closed when the chuck unit 2 is detached from the operation unit 3.

摘要： A chuck apparatus (10) includes a pair of grip members (40) driven by a piston (32) via a pair of levers (42), and the levers are rotatably supported by a body (46) via lever shafts (44). A lever shaft protrudes from the attachment surface (46b) of the body to the transport device (68), and positioning with respect to the transport device is performed by using the protruding portion.

摘要： [Object] To keep a pair of fingers included in a finger support part from shifting freely when the finger support part is detached from a chuck main body part.
[Solution] An air chuck includes: a finger support part 2 including a pair of fingers 5 and a pair of lock shafts 13; a chuck main body part 3 including an operation mechanism 6 operable to open and close the fingers 5; and linking mechanisms 4 that detachably link the finger support part 2 to the chuck main body part 3. Each of the linking mechanisms 4 causes the corresponding lock shaft 13 to shift to a non-lock position so as to render the pair of fingers 5 capable of being opened and closed when the finger support part 2 is linked to the chuck main body part 3. Each of the linking mechanisms 4 causes the corresponding lock shaft 13 to shift to a lock position and locks the pair of fingers 5 so as to render the pair of fingers 5 incapable of being opened and closed when the finger support part 2 is detached from the chuck main body part 3.
