Description

Cylinder assembly for electrohydraulic integrated push rod Technical Field The utility model relates to the technical field of electro-hydraulic push rods, in particular to a cylinder barrel assembly for an electro-hydraulic integrated push rod. Background The electrohydraulic push rod is a hydraulic driving manipulator integrating machine, electricity and liquid, is suitable for reciprocating push-pull straight reciprocating rotation at a certain angle, is driven by a servo motor, a cylinder and the like in general, and is widely applied to the departments of metallurgy, mine, electric power, coal, machinery, traffic, grain, chemical industry, cement, water conservancy, building materials, transportation and the like. The cylinder barrel of the existing electro-hydraulic push rod hydraulic cylinder is usually externally connected with an oil pipe, the oil way is exposed outside for a long time, so that the ageing of the surface of the oil way is accelerated, and because the cylinder barrel of the hydraulic cylinder is usually provided with a plurality of oil ways, the external oil way is also wound, and the oil pipe is difficult to find during maintenance. Disclosure of utility model The utility model aims to solve the technical problem of providing a cylinder barrel assembly for an electrohydraulic integrated push rod, which can avoid long-term exposure of an oil way to the external environment and solve the problem that the oil way is exposed to the outside and is easy to age. In order to solve the technical problems, the technical scheme adopted by the utility model is as follows. The cylinder assembly for the electrohydraulic integrated push rod comprises a cylinder body, wherein a cylinder cavity which is completely penetrated is formed in the center of the cylinder body, the cylinder cavity is assembled with a piston rod in a sliding mode, a cylinder head sealing piece is arranged at the front end of the cylinder cavity, a cylinder tail sealing piece is arranged at the rear end of the cylinder cavity, the piston rod penetrates through the cylinder head sealing piece, a long oil pipe and a short oil pipe which are axially arranged along the cylinder body are respectively arranged in the outer side wall of the cylinder body, an oil outlet of the long oil pipe is communicated with the cylinder cavity which is located at the front side of the right end of the piston rod, and an oil outlet of the short oil pipe is communicated with the cylinder cavity which is located at the rear side of the right end of the piston rod. Above-mentioned cylinder assembly for electro-hydraulic integrated push rod, the bottom of cylinder main part is provided with the stabilizer blade that is used for carrying out the support to the cylinder main part, and the quantity of stabilizer blade is two. Above-mentioned cylinder assembly for electro-hydraulic integrated push rod is located the cylinder main part lateral wall of piston rod right-hand member front side and is located the cylinder main part lateral wall of piston rod right-hand member rear side and installs the cylinder exhaust seat with cylinder inner chamber intercommunication respectively.
