Abstract

The utility model discloses a wood gripping oil cylinder for a loading machine. The wood gripping oil cylinder for the loading machine is characterized in that one end of a cylinder barrel and a cylinder bottom are welded, the other end of the cylinder barrel and a guide sleeve are screwed by threads, a piston rod is sheathed in the cylinder barrel by the guide sleeve, a set screw is arranged at the tail end of the piston rod, a glyd ring and a wear-resistant ring are arranged in a piston outer groove, a first O-shaped ring is arranged in an inner groove, a dustproof ring, a piston rod seal ring, a support ring and a step seal are arranged in a guide sleeve inner groove, and a second O-shaped ring and a check ring are arranged in an outer groove. Through the arrangement, the wood gripping oil cylinder for the loading machine not only meets the requirement on the action of the wood gripping oil cylinder of an excavator, but also realizes the reliability in connecting.

Description

A kind of loader is with grabbing the wood oil cylinder

Technical field

The utility model relates to a kind of oil cylinder of loading machine, is 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 utility model provides a kind of compact structure for the specific (special) requirements of present loader, and the good loader of functional reliability is with grabbing the wood oil cylinder.

The utility model is achieved through 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 utility model had both satisfied the requirement that excavator is grabbed the action of wood oil cylinder, had solved again the reliability that connects, and the utility model processing technology 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 utility model.

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 the utility model cylinder barrel 3 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 utility model is installed 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.
