Abstract
(A1) Die Erfindung betrifft eine Spannvorrichtung zum Verspannen zweier Fuegepartner, welche ein mit einem gasfoermigen oder fluessigen Medium befuelltes oder befuellbares Reservoir umfasst, das zumindest teilumfaenglich durch ein flexibles Element begrenzt wird, wobei die zu verspannenden Fuegepartner mit dem flexiblen Element derart in Kontakt gebracht werden koennen, dass durch einen im Reservoir erzeugbaren Druck ueber das flexible Element eine Kraft auf mindestens einen der zu verspannenden Fuegepartner ausgeuebt werden kann. Die Erfindung betrifft darueber hinaus ein mit dieser Spannvorrichtung durchgefuehrtes Verfahren zum Laserstrahlfuegen von zwei Fuegepartnern.
WO 2010069599 A1 UPAB: 20100712 NOVELTY - The clamping device has a reservoir (10) filled with a gaseous or liquid medium and bordered on a portion of the circumference by a flexible element (3) e.g. film or membrane. Joining parts (1, 2) to be braced are brought in contact with the flexible element such that force (F) is applied to one of the joining parts by pressure (P) that is generated in the reservoir by the flexible element. The flexible element is formed from a polymer e.g. silicon or Teflon. The flexible element is designed with a transparent surface for radiation of a laser radiation source. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for laser beam joining of two joining parts. USE - Clamping device for bracing two joining parts i.e. three dimensional joining parts. ADVANTAGE - The joining parts to be braced are brought in contact with the flexible element such that the force is applied to one of the joining parts by the pressure that is generated in the reservoir by the flexible element, thus enabling fast and flexible bracing of different shaped, complex three dimensional joining parts while effectively avoiding mechanical tensioning and additional cracking of the joining parts.
