Abstract
The utility model relates to technical field of hydraulic equipment, especially a kind of self oiling oil cylinder.It is all manual operation that existing oil cylinder adds grease, waste time and energy, and piston easily causes the wearing and tearing of oil cylinder inner wall after long-time working in reciprocating mode, reduction of service life.This self oiling oil cylinder comprises cylinder body, be arranged on the end cap of cylinder base, be located at the piston rod of cylinder interior, bottom piston rod, be provided with piston, described internal piston is provided with oil storage tank, two ends, piston left and right are provided with circular groove, are provided with ball in circular groove, and oil storage tank is connected by drawing oil pipe with circular groove, piston base is provided with two flexible rods, end cap is provided with two grooves, and flexible rod one end is fixed in groove, and the other end is fixed on piston base by wrist pin.Oil cylinder after improvement is time saving and energy saving, increases work efficiency, and make oil cylinder in to-and-fro motion, complete lubrication to piston itself and oil cylinder inner wall, decrease the wearing and tearing of piston and inwall, noise is little, rubs little, and working life extends.
Description
Technical field
The utility model relates to technical field of hydraulic equipment, especially a kind of self oiling oil cylinder.
Background technique
Hydraulic jack to carry out the various operations such as lifting, bending, alignment, extruding, shearing, rivet welding, jacking, stretching, dismounting, punching, building iron extruding, bridge, engineering machinery, directly can carry out the special tool of pressure test to pressurized container.The piston portion of hydraulic jack in working order in stretch out oil cylinder; nature will be subject to oxide, the erosion of sour gas; this protects with regard to needing us to apply appropriate grease to it; in order to avoid weather as the piston of load-supporting part and may wreck at work; but adding grease is all manual operation; waste time and energy; and piston easily causes wearing and tearing at oil cylinder inner wall after long-time working in reciprocating mode; add the active force of upper piston to bottom head covers larger; accelerate its degree of wear, reduction of service life.
Model utility content
In order to overcome existing above-mentioned deficiency, the utility model provides a kind of self oiling oil cylinder.
The utility model solves the technological scheme that its technical problem adopts: a kind of self oiling oil cylinder, comprise cylinder body, be arranged on the end cap of cylinder base, be located at the piston rod of cylinder interior, piston is provided with bottom piston rod, described internal piston is provided with oil storage tank, and two ends, piston left and right are provided with circular groove, are provided with ball in circular groove.
According to another embodiment of the present utility model, comprise described oil storage tank further and be connected by drawing oil pipe with circular groove.
According to another embodiment of the present utility model, comprise described piston base further and be provided with two flexible rods.
According to another embodiment of the present utility model, comprise described end cap further and be provided with two grooves, flexible rod one end is fixed in groove, and the other end is fixed on piston base by wrist pin.
The beneficial effects of the utility model are, time saving and energy saving, increase work efficiency, and make oil cylinder in to-and-fro motion, complete lubrication to piston itself and oil cylinder inner wall, decrease the wearing and tearing of piston and inwall, noise is little, rubs little, and working life extends.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure, 1. cylinder bodies, 2. end cap, 3. piston rod, 4. piston, 5. oil storage tank, 6. circular groove, 7. ball, 8. draw oil pipe, 9. flexible rod, 10. groove.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of self oiling oil cylinder, comprise cylinder body 1, be arranged on the end cap 2 bottom cylinder body 1, be located at the piston rod 3 of cylinder body 1 inside, piston 4 is provided with bottom piston rod 3, described piston 4 inside is provided with oil storage tank 5, piston about 4 two ends are provided with circular groove 6, ball 7 is provided with in circular groove 6, described oil storage tank 5 is connected by drawing oil pipe 8 with circular groove 6, two flexible rods 9 are provided with bottom described piston 4, described end cap 2 is provided with two grooves 10, flexible rod 9 one end is fixed in groove 10, the other end is fixed on bottom piston 4 by wrist pin.
During work, piston rod 3 drives piston 4 to pump in cylinder body 1, flexible rod 9 stretches with piston about 4, play good buffer function, alleviate the damage of piston 4 pairs of end caps 2, the ball 7 at piston 4 two ends rolls at cylinder body 1 inwall, in rolling process, the lubricant oil in oil storage tank 5 is taken out of, set up that to draw oil pipe 8 are wastes in order to avoid lubricant oil, control each rolling and take the amount of lubricant oil out of, the setting of groove 10 can correct the position of flexible rod 9, avoid skew, can be used for again depositing flexible rod 9, can fit with end cap 2 when making piston 4 move to bottom.
Oil cylinder after improvement is time saving and energy saving, increases work efficiency, and make oil cylinder in to-and-fro motion, complete lubrication to piston itself and oil cylinder inner wall, decrease the wearing and tearing of piston and inwall, noise is little, rubs little, and working life extends.
