Abstract
The utility model discloses a split type piston rod displacement sensor hydraulic cylinder and relates to the technical field of design of displacement sensor hydraulic cylinders. The split type piston rod displacement sensor hydraulic cylinder comprises a cylinder tube, a piston which is arranged inside the cylinder tube and a piston rod which is connected with the piston, the two ends of the cylinder tube are provided with a front end cover and a rear cover respectively, the portion, on the rear cover, of the tail end of the piston rod is connected with a displacement sensor, a sensing rod of the displacement sensor is inserted into the piston rod, the piston rod comprises a first body, a second body and a third body, the two ends of the second body are welded with the first body and the third body respectively, a first through hole and a second through hole are formed in the center of the second body and the center of the third body respectively, and the first through hole and the second through hole are in the same axis. An original whole piston rod deep drilling mode is converted into a split type welding forming mode when the strength of the piston rod is ensured, the split type piston rod displacement sensor hydraulic cylinder is very convenient and rapid to use, meanwhile, cost is saved, and the split type piston rod displacement sensor hydraulic cylinder can be suitable for hydraulic cylinders of any standard.
Description
Technical field
The utility model relates to the design field of displacement transducer oil hydraulic cylinder.
Background technique
The Displacement Feedback oil hydraulic cylinder is except the characteristics with oil hydraulic cylinder, can be according to the accurate feedback displacement signal of operating mode needs, measuring speed, position signal, under the cooperation of control system, give full play to the mechanization of oil hydraulic cylinder, the function of automation, realize high speed, accurate industrial automation.The induction rod of built-in displacement sensor stretches into hydraulic cylinder piston rod inside, and the motionless piston rod of the sensor piston of ining succession does reciprocating linear motion, and sensor in time feeds back stroke and the transmission of signal of oil cylinder.Built-in displacement sensor oil hydraulic cylinder key is the processing of piston rod sensing hole, particularly stroke length can't can realize with daily bit bore technique, need outside specialized factory, process, increased the oil cylinder cost, grow the time of delivery, can not satisfy the allegro market demand.
Summary of the invention
The utility model purpose is to provide a kind of simple and reasonable, Split piston bar displacement transducer oil hydraulic cylinder of saving cost for above defective.
The utility model comprises cylinder barrel, is installed in the piston in the cylinder barrel, the piston rod that is connected with piston; At described cylinder barrel two ends front cover and bonnet are set respectively; Described piston rod tail end, on bonnet the connecting position displacement sensor, the induction rod of described displacement transducer inserts in the piston rod; Described piston rod comprises the first noumenon, the second body and the 3rd body, weld with the first noumenon and the 3rd body respectively at the two ends of described the second body, at the center of described the second body and the 3rd body the first through hole, the second through hole are set respectively, described the first through hole and the second through hole are on same axis.
The utility model is on the basis that guarantees piston rod intensity, and the unitary piston rod drilling deep hole by original changes the Split type welding moulding into, and is very easy to use quick, provides cost savings simultaneously the oil hydraulic cylinder of applicable any specification.
