The invention relates to an arrangement for testing the specified characteristics and individual setting of a tool, in particular a self-driving torque wrench. The arrangement comprises a stand 15 and, acting counter to this via a screw connection 22, preferably provided with a buttress thread, a yoke 19, between which buildable spring devices 6 can be arranged, which for each configuration provides a calculable clamping force for a given compression of the spring device 6 representing what is known as the joint rigidity. The screw connection 22 is intended to apply a compression force to the spring device inserted between the stand 15 and the yoke 19 by applying a given torque to the screw connection 22 by means of the tool intended for testing. The buildable spring device 6 consists of at least one rigidly assembled pack of preferably cup springs for each specified torque and joint rigidity. <IMAGE> |
