Abstract: Disclosed herein is a tool-inclining system, which is characterized in that it is provided with a structure that is simple, compact, and able to operate according to an altogether reliable mode of operation. The system comprises: a base for securing said system to a structure that is to carry said tool, such as a robot arm; a support on which said tool is to be fixed, said support being configured in such a way that said tool fixed to said support defines a working axis (S); a connection member for connection of said support to said base, said member allowing a given angular movement of said support so that said working axis displaces, starting from a neutral position, according to a tilting movement; and fluid countering means or elastic countering means, which act on said support so as to exert an action that counters said tilting movement.

Abstract: A device for connecting a tool to an arm of a robot, comprising: —a body (2; 32) having an annular wall provided with openings (6; 36), received within which are one or more balls (8; 38), which are mobile within said openings between an inoperative position and an operative position, in said operative position said balls projecting from said wall to engage corresponding portions of said tool and clamping the latter on said arm; and —a piston (4; 34), configured for co-operating with said balls and governed fluid-dynamically between a first position and a second position, wherein, in said second position, —said piston forces said-balls into said operative position, and, in said first position, said piston releases said balls so that they can move into said inoperative position.

Abstract: Described herein is a tool-change device, in particular for industrial robot arms, of the type comprising: an annular body designed to be mounted on the wrist of a robot arm, and having a first face and a second face opposite to one another, outer side walls, and inner side walls; and an apparatus for fixing said body to a connection body coupled to said tool. The device is able to provide a totally internal connection between the connections of the robot and the tool.
