DEVICE FOR MACHINING SHAPED BODIES OF REVOLUTION Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: machining tool is moved synchronously with three drives along corresponding coordinates relative to the radial position of the tool on the part surface. A carriage horizontal displacement pickup is connected to the input of a pulse distributor which second output is connected to the input of a reading storage device. A grinding head is suspended on the carriage by a hinged lever. The first output of the pulse distributor is connected to the input of a reversible counter which outputs are connected to address inputs of the storage device. The counting direction selection output of the reversible counter is connected to additional outputs of the storage device by a trigger and a decoder. The main outputs of the storage device are connected to corresponding drive inputs through digital-to-analog converters. The information of the speed of horizontal, vertical displacement of the tool and part rotation is delivered from main outputs in pictures depending on the signal from the pickup output. EFFECT: improved structure. 4 dwg
