Abstract
The utility model relates to a hydraulic jacking cylinder, which comprises a cylinder body and a piston rod disposed inside the cylinder body, and is characterized in that two ends of the cylinder body are provided with an upper flange and a lower flange which are respectively fixedly connected with two end surfaces of the cylinder body via bolts, and end surface centers of the upper flange and the lower flange close to the cylinder body are provided with guide sleeve structures embedded into an inner cavity of the cylinder body. The hydraulic jacking cylinder has the advantages of adopting the structure of the hydraulic jacking cylinder, utilizing the flanges with the guide sleeve structures to replace oil sealing structures of traditional bolts and guide sleeves, avoiding oil leakage due to bolt looseness caused by striking and improving sealing effect. The flanges with the structures only need to be clamped once when used for processing inner holes, outer circles and end surfaces, thereby simplifying processing technology and ensuring geometric tolerance.
Description
Technical field
The utility model relates to a kind of hydraulic pressure takes blame for others, and comprises cylinder body, is located at the piston rod in the cylinder body.
Background technique
In the hydraulic press industry, hydraulic pressure is taken blame for others up and down, and the oil sealing structure all adopts nut to lock the mode of guide pin bushing, adopt this oil sealing structure to have following shortcoming: guide pin bushing nut outside and inboard wall of cylinder block are by being threaded, to the angle of thread of nut and the processing request height of form and position tolerance; In use for some time because the screw thread of nut is in use yielding, be subjected to the limiting stopper bump of piston rod repeatedly after, the easily loosening oil leakage phenomenon that produces.
The model utility content
The technical problems to be solved in the utility model provides a kind of hydraulic pressure easy to process, that be not prone to oil leakage phenomenon and takes blame for others.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hydraulic pressure is taken blame for others, comprise cylinder body, be located at the piston rod in the cylinder body, its innovative point is: described cylinder body two ends are provided with upper and lower flange, described upper and lower flange is connected and fixed by the both ends of the surface of bolt and cylinder body respectively, and the end face center of the close cylinder body of described upper and lower flange is for embedding the guide sleeve structure of inner chamber of cylinder block.
Advantage of the present utility model is: upper and lower flange is annular guide sleeve structure near the both ends of the surface of cylinder body, play piston rod and sealed cylinder block effect in the guiding cylinder body, and be connected and fixed by bolt between upper and lower flange and the cylinder body, need not at the inboard machining internal thread of cylinder ends, easy to process, also can avoid adopting the oil leakage phenomenon that causes after the long-term use of traditional nut check guide pin bushing structure.Simultaneously, adopt the oil seal structure of this upper and lower flange, in the man-hour that adds of carrying out flange, endoporus, cylindrical and end face only need a clamping to get final product, and have guaranteed form and position tolerance.
Description of drawings
The structural representation that accompanying drawing is taken blame for others for the utility model hydraulic pressure.
Embodiment
As shown in drawings, the utility model relates to a kind of hydraulic pressure takes blame for others, and comprises cylinder body 1, piston rod 2, upper flange 3, lower flange 4.
Be provided with piston rod 2 in the above-mentioned cylinder body 1, two ends are provided with upper flange 3 and lower flange 4, this upper flange 3 and lower flange 4 are connected and fixed by the both ends of the surface of bolt and cylinder body 1 respectively, and upper and lower flange is the annular guide sleeve structure that embeds cylinder body 1 inner chamber near the end face center of cylinder body 1, and piston rod 2 passes the central bore of upper and lower flange 3,4.The central bore of upper and lower flange 3,4 cooperates with piston rod 2 by seal ring, guidance tape carries out oil sealing, guiding, and the cylindrical of its end face guide sleeve structure cooperates with cylinder body 1 by seal ring and carries out oil sealing.
Adopt the hydraulic pressure of this structure to take blame for others, substitute the oil sealing structure of nut and guide pin bushing, avoided nut to be impacted and looseningly caused leakage of oil, improved sealing effect with flange with guide sleeve structure.The flange of this structure only needs a clamping to get final product when the central bore of processing flange, cylindrical and end face, has guaranteed form and position tolerance.
Claims (1)
