Abstract

Dispositivo para medir la posición de la punta de una herramienta o elemento de máquina y método de aplicación; el dispositivo mide la posición de la punta de una herramienta o un útil de una máquina, en especial de una máquina-herramienta, caracterizado por la incorporación de sensores que realizan la medida simultánea y continua de fuerzas y para obtener la magnitud exacta del descentramiento de la punta de una herramienta de manera que se posibilita el control en línea con precisión de la posición exacta de la punta o útil.#Para ello se realiza el montaje colineal respecto a su eje de todos los componentes sobre una base de fijación y una plataforma superior ensamblados colinealmente. El dispositivo de soporte está unido al dispositivo de captura y procesamiento de datos para calcular la posición de la punta de la herramienta o útil de máquinas sobre la base de que el objeto, al desplazarse sobre la superficie plana, produce una fuerza cuyas proyecciones en el plano perpendicular al eje del dispositivo están relacionadas con la posición exacta de la herramienta.Device for measuring the position of the tip of a machine tool or element and method of application; The device measures the position of the tip of a tool or a tool of a machine, especially a machine tool, characterized by the incorporation of sensors that perform simultaneous and continuous measurement of forces and to obtain the exact magnitude of the runout of the tip of a tool so that in-line control is possible with precision of the exact position of the tip or tool. # For this purpose, the collinear assembly is made with respect to its axis of all the components on a fixing base and a platform top assembled collinearly. The support device is attached to the data capture and processing device to calculate the position of the tip of the tool or machine tool on the basis that the object, when traveling on the flat surface, produces a force whose projections in the plane perpendicular to the axis of the device are related to the exact position of the tool.
