Abstract
The invention relates to a hydraulic cylinder which comprises a cylinder barrel, a piston rod, a guide sleeve, a supporting disc and a cover plate. The piston rod is arranged in the cylinder barrel in the mode of being capable of moving horizontally in a reciprocating mode. The guide sleeve is fixedly connected to the front end of the cylinder barrel. The piston rod is sleeved with the guide sleeve. The supporting disc is fixedly connected with the front end of the piston rod. The cover plate is fixedly connected to the rear end of the cylinder barrel in a sealed mode. Compared with the prior art, the hydraulic cylinder is simple in structure, an output shaft operates precisely, and dustproof airtightness is high.
Description
Technical field
The present invention relates to a kind of oil hydraulic cylinder.
Background technique
At present, common oil hydraulic cylinder, when expanding-contracting action, because load over centre, circumference coordinate unequal reason, causes producing certain rotation during piston rod action, produces the straight line motion being compounded with rotation.When due to need of work, connection is not carried out to piston rod when piston rod is installed and retrain, but when needing the straight line motion exporting accurate subsidiary rotation, the anti-rotation of piston rod will become extremely important, so need this Resolving probiems of oil hydraulic cylinder.
Summary of the invention
Technical problem to be solved by this invention is to provide the oil hydraulic cylinder that a kind of structure is simple, output shaft runs precisely, dust sealing is strong.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of oil hydraulic cylinder, comprise cylinder barrel, piston rod, guide sleeve, supporting disk and cover plate, described piston rod can horizontal reciprocating movement be placed in described cylinder barrel, described guide sleeve is fixedly connected on the front end of described cylinder barrel, and described guide sleeve is sleeved on described piston rod, described supporting disk is fixedly connected with the front end of described piston rod, and described cover plate fixed seal connection is in the rear end of described cylinder barrel.
Further, the front end sleeve of described piston rod is equipped with dust ring, and described dust ring is fixedly embedded in described guide sleeve.
Further, described piston rod is also set with seal ring, and described seal ring is fixedly embedded in described guide sleeve, described seal ring is in the rear side of described dust ring.
Further, described piston rod is also set with support ring, and described support ring is fixedly embedded in described guide sleeve, described support ring is in the rear side of described seal ring.
Further, be provided with the exhaust tube that can be communicated with described cylinder barrel inside and its outside in described cover plate, the lower end of described cover plate is provided with the bleed valve that can seal described exhaust tube.
The invention has the beneficial effects as follows: guide sleeve can lead to piston rod, avoid piston rod to run and occur deviation, piston rod is run more accurate; Dust ring and seal ring can carry out dust-proof and sealing in piston rod running, avoid being mixed into impurity in cylinder barrel, are convenient to maintenance, extend the working life of this device.
Accompanying drawing explanation
