Machine-tool for high speed machining adopting an ergonomic arrangement for functional parts thereof
Patent number: 6192572Abstract: A high speed machining machine-tool including a mechanical module having a machining station and a driving station and an equipment module with “n” number different parts located up line. The module bases are connected to a common supporting frame, with the mechanical module being fixedly connected thereto. The equipment module is connected to the machine so as to slide on its longitudinal axis. The different mobile parts of the machine-tool adopt two positions: a first, so-called “folded” position, in which the equipment module and all its parts engage each other and the mechanical module; a second, so-called “extended” position, in which the whole equipment module or a subset of its component parts have slid on the supporting frame towards the rear so as to form a transversal handling passage running through and through the machine. The invention is useful for high speed machining.Type: GrantFiled: May 27, 1999Date of Patent: February 27, 2001Assignee: Renault AutomationInventor: André Azema -
Patent number: 6116830Abstract: A telescoping protective cowling for removing part of a machine tool. The device includes at least three elements consisting of panels and one of which is stationary or relative to the frame and provided with a window with inside edges restricting the freedom of movement of a moving part. The second panel is slidable relative to the first panel along two axes, is longer than the window of the first panel and is provided with a window within which the moving part is free to move. The third panel is movable and substantially larger than the window in the first panel and receives the moving part in its central portion. As a result, the movements of the moving part in the plane of the two axes in the window in the first panel means that the second panel has a proportional mobility and is thus able to fill the opening of the window in the first panel after it has been left clear by the third panel following the movements of the moving part.Type: GrantFiled: June 18, 1998Date of Patent: September 12, 2000Assignee: Renault AutomationInventor: Andre Azema
