Abstract: A joint arrangement including a drive member rotatable about a rotation axis, the drive member including a drive member press fit surface and a drive member shape lock structure; an attachment portion having an attachment thread; and a driven member including a driven member press fit surface, a driven member shape lock structure and a through hole; wherein the joint arrangement is configured such that the driven member can be rigidly connected to the drive member by means of a press fit between the drive member press fit surface and the driven member press fit surface by threadingly engaging the attachment thread with an attachment member passing through the through hole; and wherein the joint arrangement is configured such that a shape lock is provided between the drive member shape lock structure and the driven member shape lock structure when the driven member is connected to the drive member.

Abstract: An industrial robot having a first part and a second part that are arranged to be movable with respect to each other where at least one cable extends from the first part to the second part via an internal cavity. An excess of cable extends freely through the internal cavity from the first part to the second part. At least one cable is connected to at least one of the parts via a releasable contact point that is located inside the internal cavity.

Abstract: An industrial robot comprising a manipulator with a control system, where the manipulator comprises a hollow, first robot unit (9) and a second robot unit (10) rotatable around an axle (A). The first robot unit (9) and the second robot unit (10) are arranged for rotation and/or bending in relation to each other and the second robot unit (10 includes a robot tool (11). Cables (12) are drawn through the first robot unit (9) and arranged coaxially and detachably connected with a first end (13), to the second robot unit (10), via a connection device. The connection device comprises a body (14), fixed to the first end (13) of the cables in at least one wire and the body (14) is arranged with sockets (19) for connection of power supply to the robot tool (11).

Abstract: An industrial robot with an upper robot arm (1) that comprises a first arm part 2) arranged to rotate at a second arm part (3), whereby a cable set (4) extends through both arm parts whereby a guiding device (6) for the cable set is arranged at the upper robot arm where the guiding device comprises cavities (21, 22) running through it arranged to guide at least one line within it in a sideway direction and to allow the displacement of at least one line within it in a longitudinal direction. The present invention also relates to a guiding device for a cable set for an industrial robot with a rotatable robot arm and to a use of the guiding device for an industrial robot with a rotatable robot arm.

Abstract: Device for guiding a cable set arranged at a manipulator equipped with a control device where the cable set forms an external loop/a slack in the transition between a first and a second manipulator part joined by a link including a guiding device that freely surrounds the cable set characterized in that the guiding device can be opened and includes a suspension device so that it can be suspended to rotate freely in the link section between the two manipulator parts.
