Abstract: The work-piece clamping device is provided with a clamping lever (14) which is pivotally mounted in a holder and is connected, in articulated manner, via an intermediate member (13) to an actuating member (7) which is secured against rotation and can be moved axially by a drive. The rotary drive consists, in this case, of a threaded spindle (3), rotatably mounted on the holder and driveable by a reversing motor (1), with a self-locking thread pitch which is in engagement with the moveable actuating member (7) provided with an internal thread, and of an axial spring (19) which becomes active in between actuating member and spindle when the clamping end position is reached and prevents wedging of the thread. The reversing motor (1) is connected to the threaded spindle (3) with interposition of an axial coupling (2). The threaded spindle (3) is mounted, on the coupling side, so as to be axially displaceable in a limited manner in a bearing (20) arranged axially displaceably in the holder (H) and provided with the axial spring (19). The coupling-side end of the threaded spindle (3) is arranged so as to be fixed in terms of rotation but axially displaceable in the axial coupling (2). Lastly, the axial spring (19) is arranged between the bearing (20) and a coupling-side support (20') on the holder (H). As a result of this design according to the invention, self-wedging of the thread is prevented, independently of the position in which the lever (14) assumes the actual clamping end position. <IMAGE>

Abstract: An apparatus for inserting tubes (20) into openings in tube sheets or baffles (13) in a heat exchanger such as a steam condenser (12), includes at least one, preferably two, drive members (97,103) such as air inflated tires mounted on wheels, in cooperating relationship on opposite sides of the tube for advancing the tube (20). The tires (97,103) are canted in opposite directions at acute angles for simultaneously rotating the tube (20) on its own axis, whereby the tube (20) rotates as it advances through the baffles (14). The rotation distributes stresses on the tube (20) to help prevent damage to the tube and assist in clearing the tube openings (18) within the condenser (12). The tube (20) is firmly frictionally engaged by the tires (97,103) and a predetermined amount of friction is selected and maintained to allow the tires to slip on the tube when an obstruction is encountered to help reduce damage to the tube and to facilitate passage of the tube into the condenser. A hole cleaner or pilot (130) is mounted on the leading end of the tube (20) with a wire brush (148) which rotates within the openings (18) as the tube advances, thereby cleaning them ahead of the tube. Suitable stops (150) are provided to control the fixed position of the tube (20) in the condenser (12).

Abstract: Selective compliance in up to six degrees of freedom in a magnetically levitated fine motion device, or robot wrist, with limited motion in X, Y, Z, ROLL, PITCH, YAW, is provided by controlled actuation currents applied to six electrodynamic forcer elements (5). The wrist has a stator support base (9) defining a dual periphery, carrying a number of stator magnet units (4). A shell flotor unit nests within the stator support base dual periphery, and carries forcer coils at locations corresponding to respective magnet units (4). The magnet unit (4) and related flotor coil (3) form a forcer element (5). There are a number of forcer elements (5). The vector sum of all the translational forces and rotational torques established at the forcer elements determines the X, Y, Z, ROLL, PITCH, YAW motion of the flotor. The flotor carries an end effector which may be a tool. Position and orientation of the flotor is monitored by light emitting diodes (7) and lateral effect colls. Coil currents are controlled as a composite of present position, desired final position, and desired compliance. As the fine motion device approaches its final position, the control unit changes forcer coil current patterns at various sets of forcer elements (5), to provide selected compliance in one or more degrees of freedom while approaching and finally while maintaining the desired position. Cooling is provided as needed; docking and locking provision is made to allow de-energizing the coils for cooling, motion of the base, or shutdown.
