Abstract

A gripping/clamping device for gripping/clamping objects includes a drive that drives an actuator, and a jaw movably coupled to the actuator. An elastically deformable spring element is provided between the actuator and the jaw. A braking unit is provided, by either the actuator, or a movably coupled component provided between the actuator and the drive, that is fixed when an object is gripped. The elastically deformable spring element is elastically deformed. The drive has a rotating drive shaft. The braking unit fixes the rotating drive shaft. A drive transmission with an output shaft is downstream of the drive shaft. The drive transmission is provided between the drive and the actuator. The actuator is a pinion that rotates about a rotational axis. The elastically deformable spring element is provided between the jaw and a gear rack section disposed on the jaw meshing with the pinion.
