Abstract
The invention discloses a high-performance hydraulic cylinder with an oil distribution device, belonging to the hydraulic cylinder technical field, which solves the defects that air remaining in a traditional hydraulic cylinder cannot be completely discharged during the working process because of floating in the upper part of the inner cavity of the cylinder, and thus Disel effect occurs due to the instantaneous high pressure of the air, it's easy to result in internal leakage and external leakage of the hydraulic cylinder, which drastically reduces the service life of the hydraulic cylinder. The invention mainly comprises a cylinder, in which a cylinder cover and a cylinder bottom are provided and inside which a piston and a piston rod are provided, the piston rod penetrating into the cylinder cover, in which an oil channel is provided and the inner end face of which is provided with a counter bore that is provided with an oil distribution disc inside. The big end face and check end of the oil distribution disc are separately provided with an oil hole and a groove, and the groove matches with the oil channel. The hydraulic cylinder is mainly used for engineering machinery.
Description
Technical field
The invention belongs to oil hydraulic cylinder technical field, specifically, particularly relate to a kind of high performance hydraulic cylinder with distributing device.
Background technique
The section hydraulic cylinder of prior art limits by mounting point in engineering machinery, and its hydraulic fluid port is positioned at below oil hydraulic cylinder or side.Air residual in oil hydraulic cylinder floats on inner chamber of cylinder block top, all cannot discharge in the course of the work with fluid.During hydraulic cylinder works, air produces Di Saier effect by instantaneous high pressure, probably burns Sealing and makes it lose efficacy, thus causing the internal leakage of oil hydraulic cylinder and outer seepage, having had a strong impact on the usability of oil hydraulic cylinder, reducing the working life of oil hydraulic cylinder.
Summary of the invention
Inner chamber of cylinder block top is floated in order to solve air residual in conventional cylinder in prior art, all cannot discharge with fluid in the course of the work, make air be subject to instantaneous high pressure and produce Di Saier effect, easily cause the internal leakage of oil hydraulic cylinder and outer seepage, the defect in serious reduction oil hydraulic cylinder working life, the invention provides a kind of high performance hydraulic cylinder with distributing device.
The present invention is achieved by the following technical solutions:
With a high performance hydraulic cylinder for distributing device, comprise cylinder body, cylinder body is provided with cylinder cap and cylinder bottom, is provided with piston and piston rod in cylinder body, and piston rod is through cylinder cap, and cylinder cap is provided with oil duct; Cylinder cap interior edge face is provided with counterbore, is provided with oil distribution casing in counterbore.
The large end face of described oil distribution casing and seam end are respectively equipped with oilhole and groove, and groove coordinates with oil duct.
Compared with prior art, the invention has the beneficial effects as follows:
Add oil distribution casing, make hydraulic oil above being changed into by original below or side into and out of hydraulic fluid port of cylinder cap, the air making to retain in oil hydraulic cylinder inner chamber of cylinder block top is successfully discharged along with the outflow of hydraulic oil, thus effectively the generation of solution Sealing Yin Disaier effect is burnt and Problem of Failure, improves the working life of oil hydraulic cylinder.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial enlarged drawing of part A in Fig. 1;
Fig. 3 is the plan view of oil distribution casing;
Fig. 4 is the left view of oil distribution casing.
In the drawings, 1, cylinder cap; 2, cylinder body; 3, oil distribution casing; 4, oilhole; 5, cavity; 6, groove; 7, oil duct; 8, seam end; 9, large end face; 10, piston; 11, cylinder bottom; 12, piston rod.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
With a high performance hydraulic cylinder for distributing device, comprise cylinder body 2, cylinder body 2 is provided with cylinder cap 1 and cylinder bottom 11, is provided with piston 10 and piston rod 12 in cylinder body 2, and piston rod 12 is through cylinder cap 1, and cylinder cap 1 is provided with oil duct 7; Cylinder cap 1 interior edge face is provided with counterbore, is provided with oil distribution casing 3 in counterbore; The large end face 9 of described oil distribution casing 3 and seam end 8 are respectively equipped with oilhole 4 and groove 6, and groove 6 coordinates with oil duct 7.
When mounted, the seam end 8 of oil distribution casing 3 coordinates with cylinder cap 1 counterbore in the present invention; The position of oil distribution casing 3 upper oil hole 4 and groove 6, determines according to the position of oil duct 7 on the top position of hydraulic cylinder works state and cylinder cap 1 respectively.
The present invention in use, primer fluid cylinder pressure, hydraulic oil promotes piston rod 12 and stretches out, hydraulic oil enters cylinder cap 1 by the oilhole 4 on the large end face 9 in oil distribution casing 3, groove 6 and oil duct 7 is flowed through successively after cavity 5, the air making to retain in oil hydraulic cylinder cylinder body 2 inner chamber top is successfully discharged along with the flowing of hydraulic oil, efficiently solves Sealing Yin Disaier effect and produces and burn and Problem of Failure; Meanwhile, can prevent the particulate pollutant of oil hydraulic cylinder bottom deposit etc. from flowing into oil duct 7 and contaminated liquid pressing system.
