Abstract

The invention relates to a device and method for offline rapidly detecting a hydraulic cylinder magnetic ring and belongs to the technical field of hydraulic cylinder detecting and repairing equipmentand methods. The device and method are used for offline rapidly detecting a hydraulic cylinder magnetic ring. The technical scheme is that an external power supply is connected with the +24Vdc powerline and the 0Vdc power line of a magnetic ruler; when the sensing rod of the magnetic ruler is inserted into the hydraulic cylinder, the state of the magnetic ring in the hydraulic cylinder can be determined by observing red and green LED indicator lamps at the end of a sensor head cover. The device and method for offline rapidly detecting the hydraulic cylinder magnetic ring are provided for thefirst time, and solves the long-term problem difficult to solve in the past very simply, and contributes to the detection of the magnetic ring of the hydraulic cylinder. The device is simple in structure and convenient to operate, can rapidly detect the magnetic ring without the disassembly of the hydraulic cylinder, thereby avoiding the rework caused by the missing of the magnetic ring found after the use of the hydraulic cylinder and the thermal shutdown caused thereby, greatly improving maintenance efficiency and saving a lot of working hours.

Description

technical field [0001] The invention relates to a device and method for fast offline detection of a hydraulic cylinder magnetic ring, and belongs to the technical field of hydraulic cylinder detection and maintenance equipment and methods. Background technique [0002] At present, the magnetostrictive displacement sensor (magnetic ruler for short) hydraulic cylinder is widely used in steel rolling equipment. The magnetic ruler hydraulic cylinder has the advantages of high precision, fast frequency response, large measurement range and easy automation. Limited to the steel rolling environment, most of the magnetic rulers are built-in, that is, inserted into the hydraulic cylinder. There is a magnetic ring on the magnetic scale, and the magnetic ring is located on the induction rod. Firstly, the magnetic ring and the piston are fixed, and then the induction rod is inserted into the hydraulic cylinder. The magnetic ring is located inside the hydraulic cylinder and cannot be in...
