Abstract
The utility model discloses a concealed anti-reversion self-directing hydraulic cylinder, which comprises an outer cylinder barrel, wherein the rear end of the outer cylinder barrel is fixedly provided with a rear flange; a hollow piston rod is arranged inside the outer cylinder barrel through sliding fit; the front end of the hollow piston rod penetrates through an opening at the front end of the outer cylinder barrel and extends out of the opening; an inner cylinder barrel is fixedly arranged in the hollow piston rod; a piston rod is arranged inside the inner cylinder barrel through the sliding fit; the front end of the piston rod penetrates through openings at the front ends of the inner and outer cylinder barrels and extends out of the openings; the front ends of the hollow piston rod and the piston rod are fixed together through a front flange; an axial guide groove is formed on an outer wall of the hollow piston rod; a guide pin is fixedly arranged on an outer wall of the outer cylinder barrel; and the guide pin is in sliding fit with a groove wall of the guide groove and moves along the guide groove. According to the concealed anti-reversion self-directing hydraulic cylinder, hydraulic equipment can be ensured to linearly move and do not turn over, and the concealed anti-reversion self-directing hydraulic cylinder has extremely high strength and rigidity and high bearing and operating capacity.
Description
Technical field
The utility model relates to smelting hydraulic equipment field, is specifically related to a kind of built-in anti-reverse from leading oil hydraulic cylinder.
Background technique
Oil hydraulic cylinder is the device that hydraulic pressure can be converted into mechanical energy, and large-scale smelting equipment commonly used in smelting process, when molten iron in the ladle is used to a certain degree, needs the shutoff of jumping a queue of the smelting mouth in the ladle is prevented that impurity flows out in the ladle.Receive the restriction of environment, condition, operating mode in the work, existing oil hydraulic cylinder can not guarantee straight line motion and be easy to generate upset, strength and stiffness and to bear the ability of running lower.
The model utility content
The purpose of the utility model provides a kind of built-in anti-reverse from leading oil hydraulic cylinder; Be set with the mode of structure of box type piston bar outward through piston rod; When hydraulic oil is done the time spent, promote piston rod, piston rod drives the box type piston bar through front end flange and ejects together; And be milled with guiding groove on the box type piston bar; Guide finger is installed, in big ouput force and receive condition, environment, operating mode restriction occasion and need to guarantee still can guarantee proper functioning and requirement under the demand that straight line motion can not overturn in the outer cylinder.
The technological scheme of the utility model is following:
A kind of built-in anti-reverse is from leading oil hydraulic cylinder; Include outer cylinder; The rear end of said outer cylinder is installed with rear flange, it is characterized in that: through the free stopper rod of being indecisive and changeable that is slidingly installed, the front end of said box type piston bar passes the perforate of outer cylinder front end and stretches out in the described outer cylinder; Box type piston bar internal fixation is equipped with inner cylinder tube; Through the piston rod that has been slidingly installed, the front end of said piston rod passes the perforate of passing inside and outside cylinder barrel front end successively and stretches out in the described inner cylinder tube, and the front end of said box type piston bar and piston rod is fixed together through forward flange; The outer wall of said box type piston bar is provided with axial guiding groove, is fixed with guide finger on the outer wall of said outer cylinder, and the cell wall of described guide finger and guiding groove is slidingly matched and moves along guiding groove.
Described built-in anti-reverse is characterized in that: be provided with seal ring between the fitting surface of the front end of said box type piston bar and outer cylinder front inner wall from leading oil hydraulic cylinder.
Described built-in anti-reverse is characterized in that from leading oil hydraulic cylinder: the rear end of said box type piston bar is with successively from inside to outside and tightly overlaps and copper sheathing.
The beneficial effect of the utility model:
The utility model is the structure that piston rod is set with the box type piston bar outward, does the time spent when hydraulic oil and promotes piston rod, and piston rod drives the box type piston bar through end flange and ejects together; Be milled with guiding groove on the box type piston bar; And guide finger is installed on outer cylinder, makes oil hydraulic cylinder self that very high guiding accuracy arranged, and can not reverse; And the guide mechanism design has improved the integrity of structure in outer cylinder.
