Abstract: A machining unit, particularly for machining the surface of cylindrical cavities, has a tool-holder assembly, including an electric actuator for adjustment of the radial tool position. The control signals of the actuator are transmitted to said actuator by a stationary electronic control unit via a wireless communication system. Also provided on board the tool-holder assembly is a system for electrical supply of the actuator, constituted, for example, by one or more batteries or else by an electrical-generation microsystem that exploits a portion of the flow of the high-pressure lubricant-coolant that is fed into the machining area.

Abstract: A cell for automated assembly operations, in particular for the assembly of components and accessories of multi-cylinder internal-combustion engines, includes a device for referencing the piece and clamping it in position, which includes a plate, provided with reference elements that are to engage, said plate being raisable vertically to take up the engine, setting the engine at a distance from the conveying device. The raisable plate is carried by a slide, which is mounted mobile in a direction parallel to the longitudinal direction of the line. The aforesaid slide is mounted so that it can slide on a supporting structure, which is in turn mounted oscillating about an axis parallel to the longitudinal direction of the conveying line on a structure that is rigidly connected to the fixed frame of the cell.

Abstract: A cell for automated assembly operations, in particular for the assembly of parts of multicylinder internal-combustion engines, has manipulator members that are designed for simultaneous assembly of a plurality of elements on a work piece and that are adjustable for varying the distance between the positions of said elements.
