Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments.
Fig. 1, 2 and 3 show a schematic structural diagram of an embodiment of the present invention, in which the displacement sensor is a magnetostrictive linear displacement sensor, and includes a cable 12, a base 13, a magnetic ring 14 and a measuring rod 15. The hydraulic oil cylinder mainly comprises a tail end mounting lug ring 1 and a connecting piece 2 which are connected in a welding mode, an oil cylinder tail end cover 4 and a cylinder body 7 can be connected in a welding mode, and the connecting piece 2 and the cylinder body 7 are connected through screws. The tail end cover 4 of the oil cylinder is provided with mounting holes and through holes for the oil inlet 1 and the displacement sensor 3. The piston 6 is arranged in the cylinder body 7 in a sealing mode, sealing can be achieved between the piston 6 and the cylinder body 7 through a sealing ring, the piston 6 is of a hollow structure, an inner hole is tapped and used for being connected with a piston rod 8 in a threaded mode, and sealing is achieved between the piston 6 and the piston rod 8 through a group of sealing rings. A magnetic ring 14 mounting hole and a measuring rod 15 mounting hole are formed in the middle of the piston rod 8, the diameter of the measuring rod 15 mounting hole is larger than that of the measuring rod 15, the hole depth is longer than that of the measuring rod 15, and a certain gap is guaranteed between the measuring rod 15 and the hole, and the measuring rod cannot be impacted when the piston rod retracts. The base 13 of the displacement sensor 3 is fixedly arranged on the tail end cover 4 of the oil cylinder, the magnetic ring 14 is arranged on the piston rod 8, and the rigid measuring rod 15 extends into the hole of the piston rod 8. The front end cover 10 of the oil cylinder is connected with the cylinder body 7, a sealing ring is arranged in the front end cover for sealing, and a plurality of groups of seals are arranged between the front end cover and the piston rod 8 for ensuring the sealing effect.
