초록 ▼

An adjustable stroke gripper assembly includes an adjustment member carried by a housing. The adjustment member is movable between at least a first and a second position, whereby when in the first position, retraction of the drive member moves the pair of jaws of the gripper assembly to a first open position defining a first angle therebetween, and when the adjustment member is moved to the second position, the pair of jaws open to a second open position defining a second angle which is different than the first angle. The adjustment member of the gripper assembly permits the stroke of the gripper to be adjusted to grasp workpieces of differing dimensions, and also to enable the use of the gripper assembly in environments wherein clearance requires the jaws to open to a particular angle. Furthermore, the adjustment member permits the jaw angle to be varied without replacing the pair of jaws.

대표청구항 ▼

1. A gripper assembly for use with a drive assembly having a drive member, wherein the drive member has an extended position and a retracted position, said gripper assembly comprising:a housing connected to the drive assembly; a jaw assembly carried by said housing, said jaw assembly having a pair of jaws, said pair of jaws having a closed position when the drive member is in the extended position, and at least a first open position and a second open position when the drive member is in the retracted position, wherein said first open position defines a first angle between said pair of jaws and said second open position defines a second angle between said pair of jaws; a connection assembly operably connecting said jaw assembly to the drive member; and an adjustment member carried by said housing, said adjustment member having a first contact surface and movable between at least a first position and a second position, wherein said pair of jaws open to said first open position and said connection assembly does not contact said first contact surface when said adjustment member is in said first position, and wherein said pair of jaws open to said second open position and said connection assembly contacts said first contact surface when said adjustment member is in said second position.
