Definitions

  • the invention according to the patent claim includes a new type of power chuck, which opens up new hitherto unknown possibilities.
  • power chucks or front end chucks usually had compressed air actuation or hydraulic actuation of the jaws, but this is completely different according to the invention.
  • Built-in spindle drives via screws drive the base jaws in an exciting, centric manner, which in turn can carry different top jaws.
  • the self-locking of the spindle drives and worm drives according to the invention are ideal properties of the clamping means.
  • the invention can be 2-jaw, 3-jaw, 4-jaw, 5-jaw or multi-jaw power chucks or power chucks.
  • the invention includes significant advantages in use. For example, there is no annoying whipping of the compressed air through the rooms.
  • the tensioning mechanism according to the invention is actuated by an electrical control system or also by a very simple electrical system. In this way, the clamping forces can be set in a highly variable manner externally, particularly interesting for CNC machines.
  • the speeds of the jaws can be determined and the jaw opening paths can be set longer or shorter as desired and required.
  • the power chucks according to the invention also allow a very quiet run, barely noticeable by the operating personnel.
  • the clamping device diameter can be about 300 mm - 5000 mm.
  • the power supply which is not the subject of this invention, generally takes place via slip rings or contacts which are arranged behind the clamping device flange in a protected manner.
  • the new clamping devices according to the invention are a very manageable mechanical thing, equipped with a built-in electric motor, easy service is guaranteed, especially in distant countries.

Abstract

Dans le corps du mandrin (1) est disposé un système d'entraînement des mâchoires de serrage qui est composé de 2, 3, 4, 5 tiges filetées ou plus, ces tiges étant entraînées par une transmission à vis sans fin et par une chaîne ou courroie dentée (5) entraînée par un moteur électrique (4) et qui agit simultanément sur toutes les transmissions à vis. Les tiges filetées agissent chacune sur un écrou (6) relié à une partie inférieure de la mâchoire (7) guidée qui agit avec les autres parties de la mâchoire de façon centrée. On obtient donc un mandrin de serrage dont les parties inférieures des mâchoires sont entraînées de façon centrale par des tiges filetées et des transmissions à vis sans fin; l'effet autobloquant des tiges et transmissions à vis est idéal pour le mandrin de serrage. A l'extérieur du mandrin de serrage, on agit sur le dispositif tendeur par une commande électrique.
