Dispositivo para el tratamiento térmico de una pieza de trabajo

摘要

The device comprises thermal machining tools adjustable vertical to a workpiece surface, and a drive for adjusting a working distance, where the drive is formed as a plunger drive for setting the working distance with the machining tools. The drive comprises a magnet for producing a magnetic field, and a coil arranged in the magnetic field, where the magnet and the coil are moveable relative to each other along a movement axis (10) as a function of an electric current. The magnet comprises a cavity, in which the machining tool mechanically connected with the plunger drive is arranged. The device comprises thermal machining tools adjustable vertical to a workpiece surface, and a drive for adjusting a working distance, where the drive is formed as a plunger drive for setting the working distance with the machining tools. The drive comprises a magnet for producing a magnetic field, and a coil arranged in the magnetic field, where the magnet and the coil are moveable relative to each other along a movement axis (10) as a function of an electric current. The magnet comprises a cavity, in which the machining tool mechanically connected with the plunger drive is arranged. The machining tools are led along the axis of movement, and the plunger drive is symmetrically arranged around the movement axis. A mechanical linkage takes place by a shift element such as a case rising up into the cavity. The cavity is formed as an internal bore of a permanent magnet (3) or continuous cylindric, and comprises a diameter of 20-70 mm. A first device for coarse adjustment and a second device for fine adjustment are provided for adjusting the working distance, where the first and second devices comprise a fine adjustment drive. A lifting range of the plunger drive is 5-30 mm. The machining tool is a burner or a laser comprising a lens, which is mechanically connected with the plunger drive as a part of the machining tool and arranged in the cavity. The lens is connected with the movable stored coil and the movable stored magnet of the plunger drive. The plunger drive comprises a pressure window, which outwardly seals the cavity. The burner comprises a burner shaft and a burner head connected with the burner shaft, where the burner shaft is mechanically connected with the plunger drive.
