Abstract
A kind of multi-roll straightening machine drift detection means, displacement for detecting multi-roll straightening machine drift, linear displacement transducer is fixed on framework panel with nut and pad, afterbody shows that table is connected by data wire and digital displacement, elongated hole is provided with drift, in the hole of linear displacement transducer detection bar insertion drift, magnet ring is fixed on the end face of drift by non-magnetic screw and non-magnetic pad, and magnetism isolating spacer is installed between magnet ring and drift；When reducing motor rotates, promote drift to move by drive mechanism, realize that magnet ring is slided in the detection bar of linear displacement transducer, the electric signal of linear displacement transducer output shows table by data line transfer to digital displacement, shows drift displacement.The present invention can effectively overcome the shortcomings of to converse drift displacement according to reducing motor rotating cycle and screw mandrel pitch and there is transmission chain error, and linear displacement transducer directly checks the displacement of drift by magnet ring, and data are true, reliable, accurate, and precision is high.
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 carries out continuous alternating bending straightening work as finishing equipment to sheet material, with
The shape wave defect of sheet material is eliminated, board surface quality is improved.According to the defect of strip width direction diverse location, multi-roll straightening machine has
Multigroup convexity jacking apparatus, can be adjusted with single action also linkage.Convexity jacking apparatus as multi-roll straightening machine important mechanism, its
The displacement of main element drift determines the precision of straightener, thus detection drift displacement data must truly, standard
Really.Existing technology is to install absolute value encoder on the reducing motor of driving drift movement, is rotated and enclosed according to reducing motor
Number and screw mandrel pitch converse drift displacement.But due to there is transmission chain error, the data accuracy of conversion is poor.
The content of the invention
To overcome the deficiencies in the prior art, goal of the invention of the invention is to provide a kind of multi-roll straightening machine drift detection dress
Put, to realize the purpose of accurate detection drift displacement.
To achieve the above object, linear displacement transducer of the invention is fixed on framework panel with nut and pad, tail
Portion shows that table is connected by data wire and digital displacement, and elongated hole, linear displacement transducer detection bar insertion wedge are provided with drift
In the hole of iron, magnet ring is fixed on the end face of drift by non-magnetic screw and non-magnetic pad, is installed between magnet ring and drift every magnetic
Pad；When reducing motor rotates, promote drift to move by drive mechanism, realize magnet ring in the detection bar of linear displacement transducer
Slide, the electric signal of linear displacement transducer output shows table by data line transfer to digital displacement, shows drift displacement
Amount.
The present invention compared with prior art, can effectively overcome and converse wedge according to reducing motor rotating cycle and screw mandrel pitch
Iron displacement and the deficiency that there is transmission chain error, linear displacement transducer directly check the displacement of drift by magnet ring, number
According to true, reliable, accurate, and precision is high.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is Fig. 1 I-I enlarged drawings.
Embodiment
As shown in Figure 1 and Figure 2, linear displacement transducer 7 is fixed on framework panel using nut 5 and pad 6, and afterbody leads to
Cross data wire 12 to be connected with digital displacement display table 11, elongated hole is provided with drift 8, the detection bar of linear displacement transducer 7 is inserted
In the elongated hole for entering drift 8, magnet ring 1 is fixed on the end face of drift 8, magnet ring 1 and drift 8 by non-magnetic screw 3 and non-magnetic pad 4
Between magnetism isolating spacer 2 is installed.
The magnet ring 1 of the present invention is fixed on the end face of drift 8, when reducing motor 9 rotates, and drift is promoted by drive mechanism 10
8 movements, realize that magnet ring 1 is slided in the detection bar of linear displacement transducer 7.The function of linear displacement transducer 7 is line straightening machine
Tool displacement is converted into electric signal.Generally detection bar fixation is existed in the fixed position of linear displacement transducer 7 by magnet ring 1
Displacement in detection bar measures different resistances.Detection bar connects steady-state DC voltage, it is allowed to the low current flowed through micromicroampere,
Voltage between magnet ring 1 and top, the length moved to magnet ring 1 is directly proportional.The electric signal that linear displacement transducer 7 is exported passes through
Data wire 12 is transmitted to digital displacement display table 11, shows the displacement of drift 8.
During work, linear displacement transducer 7 directly detects the magnet ring 1 of the end face of drift 8, it is to avoid revolved according to reducing motor 9
Turn-take and count and screw mandrel pitch conversion drift displacement, eliminate transmission chain error, data are true, accurate, and precision height, so that
Substantially increase the precision of multi-roll straightening machine.
