Abstract
The invention discloses a multi-roller straightener adjusting wedge detection device. The detection device is used for detecting a displacement of a multi-roller straightener adjusting wedge. A linear displacement sensor is fixed on a rack panel through a nut and pad. The tail part of the linear displacement sensor is connected with a digital displacement display meter through a data line. A long hole is formed in the adjusting wedge. The detection rod of the linear displacement sensor is inserted into the hole of the wedge. A non- magnetic screw and a non-magnetic pad fix a magnet ring on the end face of the adjusting wedge. A magnetic isolation pad is installed between the magnet ring and the adjusting wedge. When a speed reduction motor is rotating, the wedge is driven to move through a driving mechanism, sliding of the magnet ring on the detection rod of the linear displacement sensor is achieved. The electric signal outputted by the linear displacement sensor is transmitted to the digital displacement display meter through a data line and the displacement of the adjusting wedge is displayed. The multi-roller straightener adjusting wedge detection device can overcome defects that the displacement of the wedge is calculated according to rotation number of a speed reduction motor and a screw rod screw pitch and driving chain errors are existed effectively. The linear displacement sensor detects the displacement of the adjusting wedge directly through the magnet ring, and is advantaged by real, reliable and accurate data and high precision.
Description
Technical field
The present invention relates to technical field of metallurgical equipment, specifically a kind of device detected for multi-roll straightening machine drift.
Background technology
In metallurgy industry, multi-roll straightening machine, as finishing equipment, carries out continuous alternating bending straightening work to sheet material, to eliminate the shape wave defect of sheet material, improves board surface quality.According to the defect of strip width direction diverse location, multi-roll straightening machine has many group convexity jacking apparatus, can single action also linkage adjustment.Convexity jacking apparatus is as the important mechanism of multi-roll straightening machine, and the displacement of its main element drift determines the precision of straightener, so the displacement data detecting drift must truly, accurately.Existing technology installs absolute value encoder on the reducing motor driving drift movement, converses drift displacement according to reducing motor rotating cycle and screw mandrel pitch.But owing to there is transmission chain error, the data accuracy of conversion is poor.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of multi-roll straightening machine drift pick-up unit, to realize the object accurately detecting drift displacement.
For achieving the above object, linear displacement transducer nut of the present invention and pad are fixed on framework panel, afterbody is connected with digital displacement indicator gauge by data line, drift has elongated hole, linear displacement transducer test rod inserts in the hole of drift, magnet ring is fixed on the end face of drift by non-magnetic screw and non-magnetic pad, installs magnetism isolating spacer between magnet ring and drift; When reducing motor rotates, promote drift and move, realize magnet ring and slide on the test rod of linear displacement transducer by driving mechanism, the electric signal that linear displacement transducer exports to digital displacement indicator gauge, shows drift displacement by data line transfer.
The present invention compared with prior art, effectively can overcome and converse drift displacement according to reducing motor rotating cycle and screw mandrel pitch and there is the deficiency of transmission chain error, linear displacement transducer directly checks the displacement of drift by magnet ring, and data are true, reliable, accurate, and precision is high.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
Fig. 2 is the I-I enlarged drawing of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, linear displacement transducer 7 utilizes nut 5 and pad 6 to be fixed on framework panel, afterbody is connected with digital displacement indicator gauge 11 by data line 12, drift 8 has elongated hole, the test rod of linear displacement transducer 7 inserts in the elongated hole of drift 8, magnet ring 1 is fixed on the end face of drift 8 by non-magnetic screw 3 and non-magnetic pad 4, is provided with magnetism isolating spacer 2 between magnet ring 1 and drift 8.
Magnet ring 1 of the present invention is fixed on the end face of drift 8, when reducing motor 9 rotates, promotes drift 8 move by driving mechanism 10, realizes magnet ring 1 and slides at linear displacement transducer 7 test rod.The function of linear displacement transducer 7 is that a straight line mechanical displacement converts electric signal to.Usually by the fixed position of test rod fixation at linear displacement transducer 7, different resistances is measured by the displacement of magnet ring 1 on test rod.Test rod connects steady-state DC voltage, allows the small area analysis flowing through micromicroampere, the voltage between magnet ring 1 and top, is directly proportional to the length of magnet ring 1 movement.The electric signal that linear displacement transducer 7 exports transfers to digital displacement indicator gauge 11 by data line 12, display drift 8 displacement.
During work, the magnet ring 1 of linear displacement transducer 7 direct-detection drift 8 end face, avoids according to reducing motor 9 rotating cycle and screw mandrel pitch conversion drift displacement, eliminate transmission chain error, data are true, accurate, and precision is high, thus substantially increase the precision of multi-roll straightening machine.
