Abstract

A constant pressure P is built up in a pressure chamber. As a rule, compressed air is extracted for this purpose from the mains network, cleaned and microadjusted to an appropriate pressure level. The corresponding working pressure is represented electronically via a transducer module. The measuring-head holder (6) is clamped in the corresponding receptacle of the machine tool or measuring machine. If the machine traverses the measuring head, in the event of the wall being touched the push rod (2) is deflected with the feeler ball (1), the valve disc (3) rises, and the pressure P drops and generates a corresponding electronic signal. This signal is a direct indicator of the position of the wall of the workpiece in the machine co-ordinate system. <IMAGE>

Description

BESCHREIBUNG Koordinaten Meßkopf mit pneumatischem Regelkreis In einer Druckkammer wird ein konstanter Druck P aufgebaut. Im Regelfall wird hierzu Pressluft aus dem Leitungsnetz entnommen,gereinigt und auf ein entsprechendes Druckniveau feinstgeregelt.DESCRIPTION Coordinate measuring head with pneumatic control loop in one A constant pressure P is built up in the pressure chamber. As a rule, compressed air is used for this taken from the pipeline network, cleaned and brought to an appropriate pressure level finely regulated.

Über einen Wandlerbaustein wird der entsprechende Arbeitsdruck elektronisch dargestellt. The corresponding working pressure is electronically transmitted via a converter module shown.

Der Meßkopfhalter (6) ist in die entsprechendeAufnahme der Werkzeug - oder Meßmaschine eingespannt. The measuring head holder (6) is in the corresponding holder of the tool - or measuring machine clamped.

Verfährt die Maschine den Meßkopf,so wird bei Wandberührung die Stösselstange (2) mit der Tastkugel (1) ausgelenkt, der Ventilteller (3) hebt ab, der Druck P fällt ab und erzeugt ein entsprechendes elektronisches Signal.Dieses Signal ist ein direkter Indicator für die Position der Werksückwåndung im Maschinen-Koordinaten-reuz. If the machine moves the measuring head, the pushrod is activated when it comes into contact with the wall (2) deflected with the probe ball (1), the valve disc (3) lifts off, the pressure P drops out and generates a corresponding electronic signal. This signal is a direct indicator for the position of the back wall in the machine coordinate system.

STAND DER TECHNIK Es ist bekannt, daß derartige Aufgaben von elektronisch arbeitenden Meßköpfen gelöst werden.BACKGROUND ART It is known that such tasks can be performed electronically working measuring heads are solved.

Besonders bei Koordinaten-Meßmaschinen wird diese Lösung verwendet.(ZEISS Koordinaten-Meßmaschinen, RENISHAHN-Meßkopf ) Diese Meßköpfe sind sehr aufwendig im Aufbau und dadurch empfindlich im Einsatz. This solution is used especially with coordinate measuring machines (ZEISS Coordinate measuring machines, RENISHAHN measuring head) These measuring heads are very complex under construction and therefore sensitive in use.

Infrarotbetriebene Meßköpfe sind stark von der Umweltbedingung abhängig. Infrared driven measuring heads are strongly dependent on the environmental conditions.

AUFGABE Der pneumatische Meßkopf erfüllt diese Aufgabe durch seinen sehr einfachen, aus wenigen Teilen bestehenden Aufbau. Die Signalübertragung ist durch einen dünnen Schlauch gegeben,der unanfällig gegen Staub,Späne, Kühlmittel oder Temperatur ist.TASK The pneumatic measuring head fulfills this task with its very simple structure consisting of a few parts. The signal transmission is given by a thin hose that is not susceptible to dust, chips, coolant or temperature is.

Eine weitere Verbesserung wird erreicht, wenn nach Anspruch 2 die Meßkugel (1) mit Düsen ausgestattet wird. Verunreinigungen an der Werkstückwand werden abgeblasen. A further improvement is achieved if, according to claim 2, the Measuring ball (1) is equipped with nozzles. Contamination on the workpiece wall are blown off.

VORTEILE Das System löst diese Aufgabe durch seinen vereinfachten Aufbau und durch die erhöhte Robustheit sehr leicht und kostengünstig.ADVANTAGES The system solves this task with its simplified Structure and very light and inexpensive due to the increased robustness.
