Abstract

In order to grasp items in a chuck, such as a shaft or housing, it is necessary to have a device which will engage the object being grasped and not unduly damage it due to excessive force while at the same time executing the grasping under simple control. The chuck assembly shown in the drawing will perform the grasping and releasing of objects in response to a rotation of a threaded shaft and the actuation of a single air cylinder. For an object to be grasped, chuck jaws 10 must be caused to slide inwardly in the jaw support 12. Jaw support 12 is threadedly engaged with shaft 14 and then locked in place rigidly with a setscrew 16. Pivotally carried on the chuck support 12 by mounting bolts 18 are jaw actuators 20.
