Abstract
The invention provides a rotary oil cylinder and aims to overcome the defects of complex structure and the like in a hydraulic cylinder which can realize rotating movement. The oil cylinder comprises a cylinder block, an end cover, a screw rod, a piston, guide rods and a bearing, wherein the two ends of each guide rod are embedded into the end cover; the end cover is fixed to the cylinder block through a bolt; each guide rod can rotate around the axis of the guide rod but cannot perform movement with other degrees of freedom; two guide rods pass through the piston; and the outer surface of the end cover is in close fit with the inner surface of the cylinder block. When the end cover is fixed to the cylinder block, the screw rod is supported on the cylinder block through a bearing matched with the end cover, passes through the center of the piston and is in close fit with the piston through the screw thread. The rotary oil cylinder can convert linear movement into rotating movement through a spiral structure.
Description
Technical field
The present invention relates to a kind of rotating hydraulic cylinder, is exactly a kind of hydraulic actuator with spinfunction specifically.
Background technique
Along with the extensive use of modern hydraulic technology, hydraulic actuator can be realized multiple multi-form motion, at the existing deficiencies such as hydraulic cylinder structure complexity that rotatablely move of can realizing, proposes rotating hydraulic cylinder a kind of simple in structure, easy to use.
Summary of the invention
In order to overcome the existing deficiencies such as hydraulic cylinder structure complexity that rotatablely move of can realizing, the invention provides a kind of novel rotating hydraulic cylinder.
The present invention realizes by the following technical solutions: a kind of rotating hydraulic cylinder, form by cylinder body, end cap, screw rod, piston, guide rod, bearing.In the present invention, the guide rod two ends embed in the end cap, and end cap is by being bolted on the cylinder body, and guide rod can not produce the motion of other degrees of freedom except producing around self rotational.Two guide rod symmetric arrangement are passed piston, and outer surface of piston and inner surface of cylinder block closely cooperate.When end cap was fixed on the cylinder body, screw rod was by being engaged in bearings on the end cap on cylinder body, and screw rod passes the piston center, closely cooperated by self screw thread and piston.When piston when the effect lower edge of hydraulic coupling screw rod direction is moved because guide rod is fixed on the cylinder body, piston can not rotate, and rotatablely moves so screw rod produces, thereby realizes the spinfunction of oil cylinder.
The present invention utilizes helix structure that straight line motion is transformed the characteristic that rotatablely moves, and by the pressure of liquid, has realized the function that rotatablely moves of oil cylinder simply, efficiently.
