Abstract
The invention discloses a wood-grabbing cylinder for a loader. The wood-grabbing cylinder is characterized in that one end of a cylinder barrel and the bottom of the cylinder are welded together, the other end of the cylinder barrel is screwed with a guide sleeve through a thread, a piston rod is nested in the cylinder barrel through the guide sleeve, the tail end of the piston rod is provided with a set screw, a Glyd ring and a wear-resistant ring are arranged in an external groove of a piston, a first O-shaped ring is arranged in an internal groove of the piston, a dustproof ring, a piston rod sealing ring, a support ring and a step seal are arranged in an internal groove of the guide sleeve, and a second O-shaped ring and a check ring are arranged in an external groove of the guide sleeve. Through the setting, the wood-grabbing cylinder disclosed by the invention meets the action requirements, and ensures the reliability of connection.
Description
Technical field
The present invention relates to a kind of oil cylinder of loading machine, be specifically related to loader with grabbing the wood oil cylinder.
Background technique
At present loader log grabing oil cylinder volume is little, operating time work is long, and it is little to require it to possess volume, compact structure, good sealing and the characteristics such as durable in use.
Summary of the invention
The present invention is directed to the specific (special) requirements of present loader, a kind of compact structure is provided, the good loader of functional reliability is with grabbing the wood oil cylinder.
The present invention is achieved by the following technical solutions:
One end of cylinder barrel and cylinder bottom welding, the other end and guide sleeve screw by screw thread, piston rod is linked in the cylinder barrel by guide sleeve, end in piston rod inserts cylinder barrel is provided with piston, be provided with Cock screw at the piston rod tail end, Glais ring and wear ring are installed in the piston outer channel, an O type circle is installed in the internal channel, dust ring, rod seal circle, support ring and Si Te envelope are installed in the guide sleeve internal channel, the 2nd O type circle and back-up ring is installed in the outer channel.
By above setting, the present invention had both satisfied the requirement that excavator is grabbed the action of wood oil cylinder, had solved again the reliability that connects, and processing technology of the present invention is simple, assembled easy to maintenancely, was the brand-new mode of hydraulic jack in designing.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, piston rod, 2, guide sleeve, 3, cylinder barrel, 4, piston, 5, Cock screw, 6, cylinder bottom, 7, wear ring, 8, Glais ring, the 9, the one O type circle, 10, this special envelope, 11, back-up ring, 12, support ring, 13, the rod seal circle, the 14, the 2nd O type circle, 15, dust ring.
Embodiment
As shown in Figure 1, one end of cylinder barrel 3 of the present invention and cylinder bottom 6 welding, the other end and guide sleeve 2 screw by screw thread, piston rod 1 is linked in the cylinder barrel 3 by guide sleeve 2, an end that inserts in the cylinder barrel 3 at piston rod 1 is provided with piston 4, be provided with Cock screw 5 at piston rod 1 tail end, Glais ring 8 and wear ring 7 are installed in piston 4 outer channel, the one O type circle 9 is installed in the internal channel, dust ring 15, rod seal circle 13, support ring 12 and Si Te envelope 10 are installed in guide sleeve 2 internal channel, the 2nd O type circle 14 and back-up ring 11 is installed in the outer channel.
By above setting, the present invention installs wear ring 7 at piston 4 outer surface two ends grooves, plays a supportive role, eliminate the Metal Contact with cylinder barrel 3, bearing capacity is provided simultaneously, impact-absorbing, groove is installed Glais ring 8 in the middle of outer surface of piston, play the primary seal effect, have simultaneously low surface friction drag, elimination is creeped, and guarantees to have very high wear resistance, in piston 4 internal channel the one O type circle 9 is installed, fluid pressure pushes an O type circle 9 and reaches sealing effect; Piston 4 is screwed into Cock screw 5 at the piston tail end after piston rod 1 screws, prevent piston work relax, has also taken into account these characteristics of compact structure; Dust ring 15, rod seal circle 13, support ring 12, this special envelope 10 more than guarantee oil cylinder working seal reliability in guide sleeve internal surface groove.
