Abstract: The invention concerns a device for tightening threaded joints in two subsequent steps, namely a first step during which a joint is tightened to a predetermined torque snug level and a second step during which the joint is further tightened up to a final predetermined pretension level.

The power tool (10) comprises an electric brushless motor which is supplied with power from a variable frequency output inverter (11), and the gradual increase in angle speed of the power tool (10) is accomplished by a gradually increased output frequency and voltage from the power supply means (11).

Abstract: When using hand-held electrically or pneumatically driven tools, for instance angled nut tighteners, different socket wrenches or box spanners (6) are used for different work processes. In order to enable a socket to be fitted quickly to a tool, the tool is provided with a manouverable socket holder (9), which also enables the socket to be readily removed from the tool. The socket holder includes a radially movable device (10) which is connected to the tool and which can be moved to positions in which it is excentric with or concentrical with the output shaft of the tool. A spring means (13) is provided for activation of the locking device to its excentric position relative to the output shaft, such as to hold a socket firmly thereto.

The power supply includes a power converter (11) with a variable frequency and voltage output and a current responsive power shut-off device. A retardation responsive inertia device (28) is coupled to the motor rotor (25) via a spring (32) and a cam (29, 30) for corotation with the motor rotor (25) and for activation of a switch (12) as a certain predetermined retardation magnitude in the motor rotor (25) is exceeded. The latter is used for obtaining a fast torque interruption of the initial tightening step of the two-step tightening process, whereas the final tightening step is discontinued automatically as a predetermined current magnitude in the power supply is reached.

Abstract: A torque impulse power tool primarily intended for tightening threaded joints comprises a housing (10), a rotation motor (11), a torque impulse generating mechanism (13), and a reduction gearing (12) coupling the impulse mechanism (13) to the motor (11). A torsion spring (21) is associated with the reduction gearing (12) to reduce substantially the difference in deceleration between the motor (11) and the impulse mechanism (13) by yielding elastically to the driving and inertia forces of the motor (11) and the gearing (12) during each impulse generation. The torsion spring (21) is connected to absorb the reaction torque peaks developed in the gearing (12) or the driving torque peaks between the gearing (12) and the impulse mechanism (13).

Abstract: An electrical cable (20) is wrapped on and can be unwound from a reel (34) rotatable in unison with a brake drum (33) on a support (13,27). A clock spring (32) on the support (13,27) constantly urges the reel (34) to rewind the cable (20). A brake cord (36) fixed to the support (13,27) is wrapped in the rewind direction around the drum (33) and connected via a train of chain links (A,B,c) to a spring (41) that tensions the cord (36) to act as a frictional one way clutch against the drum (33) to hinder rewinding in any selected unwound position of the cable (20). To release clutch action, a further train of chain links (C,D,E) is interposed between the spring (41) and a control connection (45), by pulling of which the tension of spring (41) can be relieved to allow rewinding.

Abstract: A portable screw fastener driving tool is driven electrically from a solid state inverter and intended to be coupled to any selected one in a set of screw fastener engaging members, each demanding a drive enabling tightening of the engaged fastener by parameters (e.g. torque, angle, speed) specific to its size or type. Code elements are provided on the members in a binary code pattern specific for each member. Sensors on the tool read the code pattern on the member connected to the tool and serve it electrically to a decoding unit which transforms the read binary pattern to signals adapted to control the inverter the way the member demands.
