Abstract
The utility model discloses a sensor built-in rolling mill AGC hydraulic cylinder. The sensor built-in rolling mill AGC hydraulic cylinder comprises a cylinder body, a cylinder cover, a piston, a displacement sensor and a sensor installation block. The cylinder body is provided with an oil inlet opening and a sensor installation seat. The cylinder cover is provided with an oil return opening. The piston is installed in the cylinder body. The displacement sensor is installed on the cylinder body through the sensor installation block. 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 the built-in rolling mill AGC oil hydraulic cylinder of a kind of sensor.
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 flat thickness deviation of system 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 built-in rolling mill AGC oil hydraulic cylinder of sensor of a kind of highi degree of accuracy and high response is provided.
The utility model technological scheme adopting of dealing with problems is:
The rolling mill AGC oil hydraulic cylinder that sensor is built-in, comprises gray iron, piston, displacement transducer and installation of sensors piece, has filler opening and sensor installation seat on cylinder body, has return opening on cylinder cap; Piston is arranged in cylinder body; Displacement transducer is arranged on cylinder body by installation of sensors piece.
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, piston 3, displacement transducer 4, installation of sensors piece 5.
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 sensor built-in rolling mill AGC oil hydraulic cylinder, comprises cylinder body 1, cylinder cap 2, piston 3, displacement transducer 4 and installation of sensors piece 5, has filler opening and installation of sensors piece 5 on cylinder body 1, on cylinder cap 2, has return opening; Piston 3 is arranged in cylinder body 1; By locating stud, make piston 3 when moving up and down, have stable stroke, be unlikely to deflect and circumferentially move; Displacement transducer 4 is arranged on cylinder body 1 by installation of sensors piece 5, in order to Measurement accuracy piston 3 strokes.When the logical oil of filler opening, fluid promotes piston 3 and moves upward, now displacement transducer 4 converts the displacement signal of piston 3 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 3 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 3 and moves downward, and piston 3 connection for transmission devices promote roll and get back to initial position, and roller gap is also got back to initial state.
