Patent number: 11446758Abstract: An insulation part for supporting an electrically conductive nozzle in an insulated manner, and a laser machining head with a housing (10), through which a working laser beam path (11) is guided. The working laser beam path (11) exits on the machining side through an electrically conductive nozzle (17). The electrically conductive nozzle (17) is supported on an insulation part (18), which is supported on the housing (10), and which, for the capacitive distance measurement, is electrically connected to an oscillating circuit (24) of a distance measuring circuit (22). To monitor the presence of an inexpensive insulation part (18) in a user-friendly manner, the insulation part (18) comprises a ferromagnetic body (26) and a sensor (27) for detecting the ferromagnetic body (26) is provided on the housing (10). The sensor is connected to a monitoring circuit (29) that, in the absence of an insulation part (18), outputs a warning signal.Type: GrantFiled: July 28, 2017Date of Patent: September 20, 2022Assignee: PRECITEC GMBH & CO.

Patent number: 7075293Abstract: An inductive measurement is carried out of the distance between a workpiece (3) and a working head (1), which bears an induction coil (8), through which an alternating current flows and which is part of a resonance circuit whose oscillation frequency is monitored for changes which occur as a consequence of changes in the distance between the workpiece (3) and working head (1). In this case, the working head (1) acts on the workpiece (3) with a material (2) having a dielectric constant greater than 1. The frequency of the alternating current is in the megahertz region or just therebelow. Last but not least, the induction coil is screened from external electric fields in order to avoid the influence of parasitic capacitances.Type: GrantFiled: January 27, 2003Date of Patent: July 11, 2006Assignee: Precitec GmbHInventors: Georg Spörl, Jürgen Walz

Patent number: 6509744Abstract: The invention relates to a method and a device for measuring the distance between a sensor electrode and a workpiece. The sensor electrode forms, with the workpiece, a measuring capacitor through which an alternating current flows. A voltage present at the sensor electrode is tapped as a measuring voltage. In order to be able to remove the disturbing influence on the impedance of the measuring capacitor of a plasma forming between the sensor electrode and workpiece, the real part and the imaginary part from the measuring voltage are analyzed and used to determine the distance between the sensor electrode and the workpiece.Type: GrantFiled: February 16, 2000Date of Patent: January 21, 2003Assignee: precitec GmbHInventors: Stephan Biermann, Georg Spörl

Patent number: 6469523Abstract: The invention relates to a method for temperature compensation of an LC oscillator (8) having a machining head (4) and serving for the capacitive measurement of a distance between the machining head (4) and a workpiece (7), in which an output signal (S) of the LC oscillator (8) is transmitted to an evaluation unit (2) arranged separately from the machining head (4). The temperature (T) of the LC oscillator (8) is measured with the aid of the temperature sensor (29) and supplied to the evaluation unit (2). In the evaluation unit (2), temperature compensation of the output signal (S) of the LC oscillator (8) is effected using the measured temperature (T) and a temperature coefficient (K) which is assigned to the machining head (4) and can likewise be transmitted from the machining head (4) to the evaluation unit (2).Type: GrantFiled: February 15, 2001Date of Patent: October 22, 2002Assignee: Precitec KGInventors: Georg Spörl, Stephan Biermann

Patent number: 5366164Abstract: A nozzle for a device for machining materials, can be rigidly connected at its end opposite the nozzle tip to a connector head of the device. The connection of the nozzle with the connector head is made by a connecting element (7; 17) made of a brittle material and comprising a break-off region (11; 20). If a collision between the nozzle tip and a workpiece to be machined takes place accidentally, then the connecting element breaks in the break-off region in order to prevent further, even greater damage to the connector head, nozzle or workpiece. The break-off region is crossed by an electrical conductor (14; 27) which breaks in the event of a collision, so that in this way an alarm signal for stopping the device can be generated.Type: GrantFiled: March 10, 1992Date of Patent: November 22, 1994Assignee: Precitec GmbHInventors: Manfred Jagiella, Michael Holzmann, Georg Sporl, Ahmet Topkaya
