Abstract
Adjustable stoppers for limiting the angle at which pivotal gripper jaws are opened. The stoppers include a stop block and at least one stopper pad which is made from a shock absorbing material such as urethane. The stoppers are secured to a pivotal one of a pair of gripper jaw members of a parts gripper and positioned to abut the other of the pair of gripper jaw members. Stoppers which are provided with two or more stopper pads of different lengths are reversible and can be used to adjust the angle at which the jaw members open. A mounting assembly which includes a mounting plate, and clamping plate and a spherical collar therebetween can be used to mount a workpiece holder from the rear or at a side. Providing the mounting plate with a central circular bore allows a cylindrical support member to be inserted therein and thus axially aligned with the mounting plate. Inserting the cylindrical support member only into the spherical collar allows the support to be angularly aligned with respect to the mounting plate.
