Publication number: 20070281528Abstract: Pressing device for the relative axial movement of two parts, which are arranged coaxially with respect to one another and are moveable relative to one another only by means of a high pressing power, such as for example collet chucks or sleeves, into corresponding bores of tool or collet chuck holders. The device has an outer housing which coaxially surrounds the parts which are to be pressed and which can be swung open along an axial plane. Half-inserts can be inserted into said outer housing, which half-inserts comprise in each case two fixed plates with engagement edges for the engagement on one of the parts which are to be pressed, and an axially moveable pressure plate with an engagement edge for the engagement on the second part which is to be pressed.Type: ApplicationFiled: June 1, 2007Publication date: December 6, 2007Inventors: Martin Bronnimann, David Gerber, Ernst Gerber, Peter Tester

Patent number: 7140616Abstract: The invention relates to a sealing device which is provided with an annular circumferential groove in a preceding sealing washer and having a sealing body disposed in the groove. The width and depth of the groove are larger than the cross-section of the sealing body so that the sealing body can be axially moved in the groove and may be forced against the wall of the groove and the tool shank by inner pressure provided, for example, by a coolant.Type: GrantFiled: October 26, 2000Date of Patent: November 28, 2006Assignee: Rego-Fix AGInventor: Ernst Gerber

Patent number: 7066696Abstract: A heat shrink tool holder for holding tools and machine parts in an axial bore comprises a sleeve between the bore of the holder and the tool shank or machine part. The sleeve is a reducing sleeve that transfers a holding action exerted by the holder in its cold state to the tool shank or part. The sleeve is made of a material with a low thermal conductivity, like ceramic, and may be interchangeable or firmly fixed to the holder.Type: GrantFiled: February 28, 2005Date of Patent: June 27, 2006Assignee: Rego-Fix AGInventor: Ernst Gerber

Patent number: 7059030Abstract: Pressing device for the relative axial displacement of two mutually coaxial parts that can only be displaced towards one another by using a high pressing power, for example collet chucks or clamping sleeves, into corresponding holes in tool or collet chuck holders. The device has a housing (7) consisting of two at least partially separable shells, which can be placed coaxially around the parts to be pressed. In the closed state, the housing has coaxial annular contacting edges (19, 20) for engaging with one of the parts to be pressed. In the inner chamber (21) of the housing there is an axially displaceable pressing plate (22) with an annular contacting edge (23) for engaging with the second part to be pressed. The press plate is displaced by a number of pressure cylinders (13, 14) arranged in a ring at equal angular distances between the housing and the press plate.Type: GrantFiled: May 4, 2004Date of Patent: June 13, 2006Assignee: Rego-Fix AGInventor: Ernst Gerber
