Rotation clock unit for interchangeable arrangement of toggle lever clamps, centering devices, clinch devices, such as the term ground voltage, for use in the car body construction of the motor vehicle - industry, having a housing (7), with a rotary plate (19) for the detachable fastening of the respective clamping - and / or centering devices or the like, and the rotary plate (19) of a in the housing (7) in spaced roller bearings (3, 4) rotatably supported shaft (18) can be driven in a timed manner, with two in the housing (7) arranged at a distance from each other cylinders (34, 35), in which in each case of a longitudinally and sealingly guided piston (22, 23) is arranged, which can be charged alternately on both sides by pressure medium pressure, wherein each piston (22, 23) in each case a driving ram (24, 25) is operatively connected, the respective end with a molded-on part (26, 27) is provided, and the shaft (18) in the circumferential direction a plurality of spaced for the associated driving ram (24, 25) has equal protrusions, with which the driving ram (24, 25) with their formations (26, 27) force - and / or in a form-fitting manner in a timed manner by rectilinear stroke and the shaft (18) in this case in a direction of rotation (b) by a predetermined rotary angle measurement, and wheren="23" the longitudinal axis of the shaft (18) for the rotary plate (19) transversely to the longitudinal axes (32, 33) of the driving ram (24, 25) and the piston (22, 23) is arranged, wherein the one piston with its driving ram (24) with its cylinder (34) in each case in a plane above the other piston with its driving ram (25) and its cylinder (35) and, in addition, are laterally offset and at a distance (f) to the other piston with its driving ram is arranged in such a way that the cylinder (35) is constructed as a transport plug for a piston (23) on the one hand and the cylinder (34) for a piston formed as a locking piston (22), on the other hand, in different quadrants of a by the vertical axis (54) and transverse axis (55) of the housing (7) are formed rectangular coordinate system, with the rectilinear, imaginary line connecting the centers of the cylinder (34, 35) in each case an acute angle (α, β) with both the vertical axis (54) as well as with the transverse axis (55), and that any one of the driving ram (24) a pressure spring element (8) is associated which under elastic prestress, and has the tendency to the associated driving ram (24) in the direction of the drive shaft (18) and this in the case of need to move against undesired turning movement the form of - and / or non-positively blocked, characterized in that with an interrogator (40), which represents a structural unit which, in a recess (39) of the housing (7) between the roller bearings (3, 4) for the shaft (18) of the rotary plate (19) is arranged in an exchangeable manner, and the interrogator (40) and designed as a cassette is designed in the shape of a u -, and which in the side viewn="24" approximately in the surface of the housing (7) and has two spaced-apart webs, which the associated shaft (18) and the sensors surround.
