Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of detection of cold rolling mill oil cylinder position sensor dresses It sets, the present apparatus is realized to the Function detection after the offline periodic detection of position sensor and reparation, without carrying out disintegration failure Confirmation is analyzed by detecting the index for making the data of position sensor, performance have a quantization, to judge position sensing The reliability of device, state stability guarantee the quality for rolling plate.
In order to solve the above technical problems, the detection device of the utility model cold rolling mill oil cylinder position sensor includes lifting Rack, servo motor, electric cylinder, displacement measurement probe, normal data show table and mounting seat, and the elevator platform, which is equipped with, to be risen Drop plate and detection platform, the servo motor are installed on the lifter plate by side plate, and the electric cylinder is set to by L-bracket The lifter plate, the servo motor drive the electric cylinder telescopic displacement, and institute's displacement measurement probe is set to the electric cylinder And the telescopic displacement data of electric cylinder are detected, the signal output end of institute's displacement measurement probe connects the normal data and shows table Show that telescopic displacement data detected, the mounting seat are set to the detection platform and are used to install measured position sensor, The electric cylinder and measured position sensor are located at same axis and vertical with the detection platform.
Further, the present apparatus further includes that limit switch, the limit switch interval up and down are set to the lifter plate simultaneously up and down And limit the telescopic displacement distance of the electric cylinder.
Further, the axis of institute's displacement measurement probe and the depth of parallelism of electric cylinder telescopic displacement axis are less than 0.02mm.
Since the detection device of the utility model cold rolling mill oil cylinder position sensor uses above-mentioned technical proposal, i.e., originally The servo motor of device is installed on the lifter plate of elevator platform by side plate, and electric cylinder is set to lifter plate, servo by L-bracket Motor driven electric cylinder telescopic displacement, displacement measurement probe are set to electric cylinder and detect the telescopic displacement data of electric cylinder, displacement The signal output end connection normal data of measuring probe shows that table shows telescopic displacement data detected, and mounting seat, which is set to, to be risen The detection platform of drop rack for installing measured position sensor, electric cylinder and measured position sensor be located at same axis and It is vertical with detection platform.The present apparatus realizes the Function detection to the offline periodic detection of position sensor and after repairing, without into The confirmation of row disintegration failure is analyzed by detecting the index for making the data of position sensor, performance have a quantization, thus Judge reliability, the state stability of position sensor, guarantees the quality for rolling plate.
Detailed description of the invention
