Abstract
The utility model discloses an anti-rotation type translation telescopic oil cylinder, comprising a piston (3), a piston rod (5), a cylinder body (1), an anti-rotation nut (2) and an anti-rotation guide rod (4). The anti-rotation nut (2) and the piston (3) are fixedly installed, the anti-rotation guide rod (4) and the cylinder body (1) are fixedly installed, and the piston (3) and the piston rod (5) are fixedly installed. The square anti-rotation guide rod (4) penetrates through an inner square hole of the anti-rotation nut (2), and the cylinder body (1), the piston (3) and the piston rod (5) are coaxially installed. When the oil cylinder makes telescopic action, the piston (3) and the piston rod (5) make reciprocating action in the cylinder body (1) to drive the anti-rotation nut (2) to make reciprocating action on the anti-rotation guide rod (4). The appearance of the anti-rotation guide rod (4) forms oil cylinder action guidance through the inner square hole of the anti-rotation nut (2) so that the autoroatation of the oil cylinder can be eliminated. The telescopic oil cylinder has a simple structure, realizes single smooth motion and meets the requirement of accurate action of a high-precision mechanism.
Description
Technical field
The present invention relates to a kind of telescopic oil cylinder, particularly a kind of anti-rotatable translation telescopic oil cylinder.
Background technique
In a lot of engineering designs, the action of motion is to drive by telescopic oil cylinder to finish.Common telescopic oil cylinder is just made common flexible straight line motion, and common telescopic oil cylinder is made up of piston, piston rod, guide sleeve and cylinder body.Piston is fixedlyed connected with piston rod and is integral, piston rod pass guide sleeve and and piston, guide sleeve overlap successively in the cylinder body of packing into, wherein guide sleeve is fixedlyed connected with cylinder body and is integral, place the other end of the piston rod relative with piston, piston, piston rod, guide sleeve and cylinder body guarantee coaxial installation.Pressure oil acts on the piston, promotes to make expanding-contracting action with the piston rod of piston one.During common telescopic oil cylinder expanding-contracting action,, be a kind of compound straight line motion of rotation because the inequality that load over centre, circumference cooperate causes the action of oil cylinder piston bar can produce certain rotation.When mechanism action only had living space now to position constraint rather than connection constraints, wherein most typical was exactly pick-and-place mechanism, and this change of team certainly brings departing from of mechanism's pick-and-place device and pick-and-place target, caused the pick-and-place action to be lost efficacy, even caused mechanism destroyed.
The composite straight line motion of common telescopic oil cylinder can't realize the accurate of mechanism action, has significant limitation on the engineering application that mechanism drives.
The model utility content
The purpose of this utility model is to provide a kind of anti-rotatable translation telescopic oil cylinder, solves the action of oil cylinder piston bar and has rotation, the not high problem of mechanism's work accuracy.
A kind of anti-rotatable translation telescopic oil cylinder, comprising: piston, piston rod, guide sleeve and cylinder body also comprise: rotating-proof nut, anti-rotation guide rod.Piston rod is a hollow stem, and rotating-proof nut places piston inner hole and screw, the non-endoporus screw that goes out rod end of anti-rotation guide rod and cylinder body, and piston places piston rod one end and welding fixing, and piston is coaxial with piston rod; The anti-rotation guide rod is a square pole, and the rotating-proof nut center has square opening, and anti-rotation guide rod and rotating-proof nut square opening are complementary, the anti-rotation guide rod places the rotating-proof nut central bore, one end and cylinder body screw, the other end is unsettled, cylinder body and the coaxial installation of piston, piston rod and guide sleeve.
During the oil cylinder expanding-contracting action, the reciprocating action in cylinder body of piston, piston rod drives rotating-proof nut reciprocating action on the anti-rotation guide rod, when rotation trend may take place oil cylinder, the square profiles of anti-rotation guide rod forms the cylinder action guiding by square hole in the rotating-proof nut, eliminates the oil cylinder rotation.The effective sliding distance of rotating-proof nut on the anti-rotation guide rod can not be less than the flexible stroke of oil cylinder.
Telescopic oil cylinder of the present utility model is simple in structure, has realized single smooth motion on the forms of motion, helps the accurate control of mechanism action, has satisfied the demand of highi degree of accuracy mechanism precision maneuver.

Embodiment
A kind of anti-rotatable translation telescopic oil cylinder, comprising: piston 3, piston rod 5, guide sleeve 6 and cylinder body 1 also comprise: rotating-proof nut 2, anti-rotation guide rod 4.Rotating-proof nut 2 places piston 3 endoporus and screw, and anti-rotation guide rod 4 places cylinder body 1 non-ly goes out the endoporus of rod end and be connected with cylinder body 1 screw, and piston 3 places piston rod 5 one ends and welding fixing, and piston 3 is coaxial with piston rod 5; Anti-rotation guide rod 4 is a square pole, and rotating-proof nut 2 endoporus are square opening, and anti-rotation guide rod 4 places rotating-proof nut 2 central bore, and an end is connected with cylinder body 1 screw, the unsettled installation of the other end; Cylinder body 1 and piston 3, piston rod 5 and guide sleeve 6 coaxial being installed together.
During the oil cylinder expanding-contracting action, piston 3, piston rod 5 reciprocating action in cylinder body 1 drive rotating-proof nut 2 reciprocating action on anti-rotation guide rod 4, when rotation trend may take place oil cylinder, the square profiles of anti-rotation guide rod 4 forms the cylinder action guiding by square hole in the rotating-proof nut 2, eliminates the oil cylinder rotation.The effective sliding distance of rotating-proof nut 2 on anti-rotation guide rod 4 can not be less than the flexible stroke of oil cylinder.
