Abstract
The utility model discloses a verifying device for a tension sensor of a rolling mill. The verifying device comprises a hydraulic jack and a standard sensor, a top rod end of the hydraulic jack is provided with a first screw hole, the surface of the standard sensor is provided with a second screw hole and a third screw hole, the verifying device also comprises a steel column body, an upper section and a lower section of the steel column body are a drawing-down cylinder, the cylinder surface is provided with outer thread, the upper section of the steel column body is screwed in the first screw hole of the top rod of the hydraulic jack, the lower section of the steel column body is screwed in the second screw hole of the standard sensor, the steel column body is provided with a through hole matched with the third screw hole, and a bolt is adopted to penetrate through the through hole for fixing. The verifying device for the tension sensor of the rolling mill is simple in structure, avoids damage to the standard sensor, enables forces of the hydraulic jack which are acted on the standard sensor and the verified tension sensor to lie in the same straight line, avoids generation of verification errors and ensures quality of strip steel rolling.
Description
Technical field
The utility model relates to metallurgical instrument field, relates in particular to a kind of calibration equipment for the milling train tension pick-up.
Background technology
Tension pick-up is a kind of a kind of sensor special that the belt steel rolling process is controlled that uses on the milling train, and it has played crucial effect to the quality of band steel.In order to guarantee in the operation of rolling, to keep constant controlled tension force with steel, need carry out the cycle verification to tension pick-up, to keep data that tension pick-up detected in check-verifying period accurately and reliably.The method of calibration of common tension pick-up generally be stacked in standard transducer online by on the verification tension pick-up device, and the action direction unanimity of confining force, two sensor reinforcings to being stacked together then, the size of the signal of exporting according to standard transducer and compared by the size of verification tension pick-up institute output signal is determined by the accuracy of verification tension pick-up.But in this checking procedure, need hydraulic jack to being stacked in two sensor reinforcings together, do not connect reliably owing to stack, when hydraulic jack is afterburning, the power that acts on the standard transducer just might be out-of-line and produce component, cause verification to produce error, thereby tension pick-up can not get accurate verification, influence checking precision, and then influenced the belt steel rolling quality; And hydraulic jack and standard transducer stack installs inconvenient instability, causes the damage of standard transducer.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of calibration equipment for the milling train tension pick-up.
To achieve these goals, the technical solution adopted in the utility model is: a kind of calibration equipment for the milling train tension pick-up, comprise hydraulic jack and standard transducer, the push rod end of hydraulic jack has first screw, the standard transducer surface has second screw and the 3rd screw, also comprise a steel column, the epimere of steel column and hypomere are the undergauge right cylinders, periphery is provided with external thread, the epimere of steel column is screwed in first screw of hydraulic jack push rod, and the hypomere of steel column is screwed in second screw of standard transducer; Have the through hole that is complementary with the 3rd screw on the steel column, and adopt bolt to penetrate fixing.
As preferably, the 3rd screw is two, opens on standard transducer symmetrically.
Compared with prior art, advantage of the present utility model is: simple in structure, and avoided the damage of standard transducer, and made hydraulic jack act on standard transducer and be in same straight line by the power of verification tension pick-up, avoid the generation of verify error, guaranteed the quality of belt steel rolling.
