Beschreibungdescription
Kraftspannfutter 300 mm - 5000 mm Die Erfindung nach dem Patentanspruch beinhaltet eine neue Art von Kraftspannfuttern, die neue bisher nicht gekannte Möglichkeiten eröffnet. Hatten früher in der Regel Kraftspannfutter oder auch Vorderendfutter genannt, eine Pressluftbetätigung oder hydraulische Betätigung der Backen, so ist das nach der Erfindung gänzlich anders. Eingebaute Spindeltriebe über Schnekken treiben zentrisch spannend die Grundbacken an, die ihrerseits verschiedene Aufsatzbacken tragen können. Die Selbsthemmung der Spindeltriebe und Schneckentriebe nach der Erfindung, sind ideale Eigenschaften der Spannmittel.Power chuck 300 mm - 5000 mm The invention according to the patent claim contains a new type of power chucks that offer new, previously unknown possibilities opened. In the past they usually had power chucks or front-end chucks called, a compressed air actuation or hydraulic actuation of the jaws, so is completely different according to the invention. Built-in spindle drives via worms centrically drive the base jaws, which in turn have various top jaws can carry. The self-locking of the spindle drives and worm drives according to the Invention, are ideal properties of the clamping devices.
Nach der Erfindung kann es sich um 2-Backen-, 3-Backen-, 4-Bakken-, 5-Backen- oder Mehrbackenkraftspannfutter oder Kraftspannplanscheiben handeln. Die Erfindung beinhaltet wesentliche Vorteile im Gebrauch. So entfällt zum Beispiel das lästige Peitschen der Pressluft durch die Räume. Extern von den Kraftspannfuttern wird durch ein elektrisches Steuerungssystem oder auch durch ein sehr einfaches elektrisches System der Spannmechanismus nach der Erfindung betätigt. So können extern, - interessant besonders bei CNC-Maschinen -, die Spannkräfte hoch variabel eingestellt werden. Die Geschwindigkeiten der Spannbacken sind bestimmbar und die Backenöffnungswege können nach Wunsch und Erfordernis länger oder kürzer eingestellt werden. Dies sind Dinge, die bei den bisher bekannten Systemen nicht erreichbar waren.According to the invention, it can be 2-jaw, 3-jaw, 4-jaw, Handle 5-jaw or multi-jaw power chucks or power chucks. the Invention has significant advantages in use. For example, it is not applicable the annoying whipping of compressed air through the rooms. External from the power chucks is made by an electrical control system or by a very simple one electrical system actuates the clamping mechanism according to the invention. So can external, - interesting especially with CNC machines -, the clamping forces can be set to be highly variable. The speeds of the clamping jaws can be determined and the jaw opening paths can be longer or shorter as desired and required can be set. These are things that the previously known systems did not were attainable.
Die Kraftspannfutter nach der Erfindung erlauben ferner einen 1 sehr leisten Lauf, vom Bedienungspersonal kaum wahrnehmbar. The power chucks according to the invention also allow a 1 very run, barely noticeable by the operating staff.
Der Spannmittel-Durchmesser kann etwa 300 mm - 5000 mm betragen. The clamping device diameter can be around 300 mm - 5000 mm.
Die Stromzuführung, die nicht Gegenstand dieser Erfindung ist, erfolgt in der Regel über Schleifringe oder Kontakte, die hinter dem Spannmittelflansch geschützt angeordnet sind. The power supply, which is not the subject of this invention, takes place usually via slip rings or contacts behind the clamping device flange are arranged protected.
Die Kosten für die neuen Kraftspannmittel nach der Erfindung sind geringer, so daß in breitem Maße ein Kraftspannmittel dort zur Verfügung stehen kann, wo es sonst aus finanziellen Gründen nicht angeschafft werden konnte. The costs for the new power clamping means according to the invention are less, so that a power clamping means are widely available there where it could otherwise not be purchased for financial reasons.
Da es sich bei den neuen Spannmitteln nach der Erfindung um eine sehr überschaubare mechanische Sache handelt, ausgestattet mit einem eingebauten Elektromotor, so ist ein leichter Service besonders in weit entfernte Länder gewährleistet. Since the new clamping means according to the invention is a very manageable mechanical thing, equipped with a built-in Electric motor, so an easy service is guaranteed especially in distant countries.
