Description

A kind of gas-liquid force increasing pressure cylinder
[technical field]
The utility model relates to a kind of pressure cylinder, particularly be a kind of improvement invention of gas-liquid force increasing pressure cylinder.
[background technique]
The gas-liquid force increasing pressure cylinder is as cylinder, oil hydraulic cylinder, it is a kind of executive component, because the gas-liquid force increasing pressure cylinder has the big Pressure characteristics of the flexibly quick and oil hydraulic cylinder of cylinder concurrently, so, be widely used on the various machinery equipment at many local cylinder, oil hydraulic cylinders of replacing.But existing its pressurized cylinder of gas-liquid force increasing pressure cylinder is generally two-part composition up and down, and two halves pressurized cylinder junction compresses for sealing or is threaded up and down, has the junction leakage of oil in various degree, and the flimsy defective of Sealing.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of gas-liquid force increasing pressure cylinder that solves pressurized cylinder leakage of oil problem.
For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:
A kind of gas-liquid force increasing pressure cylinder, comprise the upper end cap that is fixedly connected sequentially up and down together, last cylinder sleeve, pressurized cylinder, following cylinder sleeve, lower end cap, on described, lower end cap is respectively equipped with intake interface, described going up is provided with charged piston up and down successively and presses oily piston in the cylinder sleeve, charged piston and press between the oily piston and be provided with elastomer, described charged piston has the supercharging push rod, it is characterized in that: described pressurized cylinder is a monolithic construction, described pressurized cylinder is provided with intake interface, this intake interface communicates with the pressurized cylinder lower end surface, described pressurized cylinder has the shoulder hole of up/down perforation, the shoulder hole that described supercharging push rod passes oily piston of described pressure and described pressurized cylinder upper end matches, be socketed with piston rod in the shoulder hole of described pressurized cylinder lower end, the described cylinder sleeve bore of going up, press oily piston lower end, shoulder hole in the pressurized cylinder, the piston rod upper end surrounds the sealed volume of an oil storage.
The pressurized cylinder of this gas-liquid force increasing pressure cylinder partly adopts monolithic construction, and the pressurized cylinder of the existing gas-liquid force increasing pressure cylinder of replacement is the structure of two-part combination up and down, so just do not have pressurized cylinder leakage of oil problem.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
[embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and working principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1, this gas-liquid force increasing pressure cylinder comprises the upper end cap 2 that sets gradually up and down, last cylinder sleeve 6, pressurized cylinder 11, following cylinder sleeve 13, lower end cap 15, on, lower end cap is by screw rod 17, nut 1 compresses, with upper end cap, last cylinder sleeve, pressurized cylinder, following cylinder sleeve, lower end cap is fixed together, on, lower end cap is respectively equipped with intake interface 18,16, described going up is provided with charged piston 3 up and down successively and presses oily piston 7 in the cylinder sleeve 6, charged piston and press and be provided with pressure spring 4 between the oily piston, described charged piston lower end has supercharging push rod 5, described pressurized cylinder 11 is an integral body, shoulder hole with up/down perforation, the shoulder hole that described supercharging push rod 5 passes oily piston 7 of described pressure and described pressurized cylinder 11 upper ends matches, be socketed with piston rod 14 in the shoulder hole of described pressurized cylinder 11 lower ends, described cylinder sleeve 6 endoporus of going up, press oily piston 7 lower ends, shoulder hole in the pressurized cylinder 11, piston rod 14 upper ends surround the sealed volume 10 of an oil storage, described pressurized cylinder 11 upper ends also are provided with sealing gasket 9, and compress by the gland nut 8 that is threaded with pressurized cylinder, described pressurized cylinder 11 is provided with intake interface 12, and this intake interface communicates with the pressurized cylinder lower end surface.
When needs gas-liquid force increasing pressure cylinder is worked, at first source of the gas is to intake interface 12 air feed that are positioned at pressurized cylinder 11 sides, promote piston rod 14 and arrive specified position downwards rapidly, then, source of the gas is to intake interface 18 air feed that are positioned at upper end cap, it is downward to promote charged piston 3, supercharging push rod 5 heads into the shoulder hole of pressurized cylinder upper end, and the oil storage in the sealed volume 10 is compressed, and produces big oil pressure, thereby make piston rod have big thrust, to satisfy the real work needs; When the supercharging push rod heads into the shoulder hole of pressurized cylinder upper end, release from the gap between the shoulder hole of supercharging push rod and pressurized cylinder upper end for preventing the oil storage in the pressurized cylinder, sealing gasket 9 has played the effect of sealing.
In sum, adopt the gas-liquid force increasing pressure cylinder of technique scheme, solved pressurized cylinder leakage of oil problem, will produce good using effect in actual applications, and be subjected to users' welcome.
