Electro-hydraulic device for copying three-dimensional mechanical profiles that cannot be expressed analytically.

摘要

The invention refers to an electro-hydraulic device for copying three-dimensional mechanical profiles that cannot be expressed analytically, and is designed to be used mainly in the automotive industry, for the serial multiplication of vehicle parts. The device is made up of an incremental device (1) which supplies an analogue electrical signal at its output to two servo valves (2 and 3) and the hydraulic signals that are obtained at their output are transmitted to a hydraulic cylinder (4 and 5, respectively) with a position transducer (6 and 7, respectively) mounted onto its rod. The electro-hydraulic signals obtained at the output of the position transducers (6 and 7) are applied to a regulating neuronal network (8) which, by interpolation with spline functions in between the learned points on the surface of the spatial profile to be made, supplies an analogue electrical signal at its output, which is applied to another servo valve (9) that controls a third hydraulic cylinder (10) whose role is to engage the cutter (11).
