Abstract
The invention discloses an electro-hydraulic angle turning device capable of accurately controlling angles, and relates to industries such as engineering machinery and ferrous metallurgy. The electro-hydraulic angle turning device comprises a support base, a rack cylinder and a gear are arranged on the support base, and the rack cylinder mainly comprises a cylinder barrel, a piston rod, pistons at two ends of the piston rod, and glands at two ends of the cylinder barrel. The piston rod is provided with teeth meshed with the gear. A magnetostriction displacement sensor is penetratingly arranged on one of the two glands, a magnetic ring is connected to the piston close to the gland, the detection end of the magnetostriction displacement sensor is penetratingly arranged in the magnetic ring, and linear displacement analog signals provided by the magnetostriction displacement sensor are converted into gear swing angles under the control of a PLC (programmable logic controller). One of the glands is connected with a sensor shield, and the other end of the magnetostriction displacement sensor is arranged in the sensor shield. The electro-hydraulic angle turning device has the advantages that the linear displacement analog signals provided by the magnetostriction displacement sensor are converted into the gear swing angles under the control of the PLC, operators are enabled to know working conditions more visually, and thus, working efficiency is improved.
Description
Technical field
