Abstract
The utility model discloses an AGC hydraulic cylinder. The AGC hydraulic cylinder comprises a cylinder body, a cylinder cover, a dust cover, a cover plate, a piston, a displacement sensor, a displacement sensor installation block, a pressure sensor installation block, and a pressure sensor. The cylinder body is provided with an oil inlet opening. The cylinder cover is provided with an oil return opening. The piston is installed in the cylinder body. The cover plate is connected with the piston. The dust cover is connected between the cover plate and the cylinder cover. The displacement sensor is installed on the cylinder body through the sensor installation block. The pressure sensor is installed on the pressure sensor installation block which is connected with the cylinder body. According to the utility model, the stroke of the piston is measured accurately through the displacement sensor installed on the cylinder body, so the advantage of high-accuracy and high-response servo control can be realized.
Description
Technical field
The utility model relates to a kind of AGC oil hydraulic cylinder.
Background technique
Rolling mill AGC system is the accurate adjustment control system being applied on cold rolling and hot rolling mill, is also constituent element very important in automatic control system.It is bearing eliminating and reducing the products thickness tolerance producing in the operation of rolling of task, to guarantee product thickness precision.Oil hydraulic cylinder, as critical component in this system, remains in larger defect at aspects such as precision and response times at present.
Model utility content
The utility model object is to solve the deficiencies in the prior art, and the AGC oil hydraulic cylinder of a kind of highi degree of accuracy and high response is provided.
The utility model technological scheme adopting of dealing with problems is:
An oil hydraulic cylinder, comprises gray iron, dust-proof cover, cover plate, piston, displacement transducer, displacement transducer mounting blocks, pressure transducer mounting blocks, pressure transducer, has filler opening on cylinder body, has return opening on cylinder cap; Piston is arranged in cylinder body; Cover plate is connected with piston, and dust-proof cover is connected between cover plate and cylinder cap, and displacement transducer is arranged on cylinder body by installation of sensors piece, and pressure transducer is arranged on the pressure transducer mounting blocks being connected with cylinder body.
The beneficial effects of the utility model are: the utility model is accurately measured piston stroke by the displacement driver being arranged on cylinder body, realize highi degree of accuracy and high response servocontrol.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: cylinder body 1, cylinder cap 2, dust-proof cover 3, cover plate 4, piston 5, displacement transducer 6, displacement transducer mounting blocks 7, pressure transducer mounting blocks 8, pressure transducer 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the utility model provides a kind of AGC oil hydraulic cylinder, comprise cylinder body 1, cylinder cap 2, dust-proof cover 3, cover plate 4, piston 5, displacement transducer 6, displacement transducer mounting blocks 7, pressure transducer mounting blocks 8, pressure transducer 9, on cylinder body 1, have filler opening, on cylinder cap 2, have return opening; Piston 5 is arranged in cylinder body 1; Cover plate 4 is connected with piston 5, and dust-proof cover 3 is connected between cover plate 4 and cylinder cap 2, in order to guarantee the spatter property of piston 5.Displacement transducer 6 is arranged on cylinder body 1 by installation of sensors piece 7, in order to Measurement accuracy piston 5 strokes.Pressure transducer 9 is arranged on the pressure transducer mounting blocks 8 being connected with cylinder body 1, is used for measuring the pressure of piston 5 cylinder body 1 inner fluid when the interior motion of cylinder body 1.When the logical oil of filler opening, fluid promotes piston 5 and moves upward, now displacement transducer 6 converts the displacement signal of piston 5 to electrical signal, with roller gap just the value of establishing compare, by closed-loop system feed back to control system with these regulating piston 5 strokes make its promote other transmission devices according to predetermined displacement campaign to reach the requirement of accurate adjusting roller gap.After the operation of rolling completes, the logical oil of return opening, promotes piston 5 and moves downward, and piston 5 connection for transmission devices promote roll and get back to initial position, and roller gap is also got back to initial state.
