Description
Technical field
The present invention relates to cylinder engine technical field, particularly a kind of telescopic cylinder, specifically a kind of selflubricating synchronous working cylinder.
Background technique
The sealing of tradition cylinder adopts rubber seal, and this seal form exists following shortcoming:
1) the necessary periodical repair of cylinder, cannot long storage periods be realized: rubber seal must with corresponding lubricating grease, lubricant oil with the use of, and lubricating grease is thick, dry and cracked with becoming sticky after cylinder storage certain hour, and make seal ring swell, the frictional force of motive sealing is increased, thus causes piston etc. normally to work.Therefore, cylinder must periodical repair, cylinder is decomposed, cleaning, the seal ring that more renews assemble, debug.Loaded down with trivial details service work needs a large amount of manpower and materials of cost and time, and especially for weaponry, the series of problems that service work brings shows particularly outstanding.
2) multi cylinder poor synchronization: due to the difference existed between cylinder individuality, for requiring the situation that multiple cylinder synchronization combining uses, the synchronism in working procedure between each cylinder is poor, is unsuitable for synchronism and requires high occasion.
Summary of the invention
The object of the invention is to solve above-mentioned problems of the prior art, and provide a kind of selflubricating synchronous working cylinder, this cylinder is applicable to the occasion that axial installation dimension is little and stroke is grown.
The present invention is achieved through the following technical solutions:
A kind of selflubricating synchronous working cylinder, comprises cylinder body, air input joint, adjustment ring, piston rod, termination, large piston, cylinder sleeve, small piston, one-level guide sleeve and secondary guide sleeve; Air input joint is arranged in the left port of cylinder body, adjustment ring, large piston, cylinder sleeve and one-level guide sleeve is settled from left to right successively in cylinder body, adjustment ring and air input joint are connected and fixed, large piston and cylinder sleeve are connected and fixed, large piston offers vent, one-level guide sleeve is arranged on cylinder body right output port, and cylinder sleeve interts in one-level guide sleeve and one-level guide sleeve is spacing to cylinder sleeve; Small piston, piston rod and secondary guide sleeve is settled from left to right successively in cylinder sleeve, small piston and piston rod are connected and fixed, secondary guide sleeve is arranged on cylinder sleeve right output port, and piston rod interts in secondary guide sleeve and secondary guide sleeve is spacing to piston rod, and termination is arranged in the right output port of piston rod; Between air input joint and cylinder body, large between piston and cylinder sleeve, inboard wall of cylinder block is all provided with rubber seal near the position of right output port and inboard wall of cylinder liner near the position of right output port; Vent on cylinder body, air input joint, adjustment ring, large piston, large piston, cylinder sleeve, small piston, piston rod, one-level guide sleeve, secondary guide sleeve and termination are all positioned on same axis.
Cylinder of the present invention is a kind of multiple cylinder synchronous working, the telescopic cylinder directly used after long storage periods (10-20), solves the problem of the non-maintaining and cylinder poor synchronization of cylinder long storage periods.Cylinder intake air flow of the present invention adopts inlet hole orifice size control methods, by adding the tolerance of tight air input joint inlet hole machining, the difference between different air input joint charge flow rates (inlet hole size) is controlled in less scope.Cylinder of the present invention measures piston stroke and original volume, is adjusted the volume of adjustment ring, control the difference of the original volume of coefficient each cylinder in less scope by the method (duplicate removal method) of repair adjustment ring.
Further, large piston and small piston are all provided with C shape seal ring, and C shape seal ring open at one end is towards the inlet end of cylinder.C shape seal ring sectional shape is in " C " shape, there is steel spring supporting inside, outside parcel by polytetrafluoroethylmaterial material forms, during assembling, " C " shape open at one end is towards the inlet end of cylinder, in using process, after the open at one end of C shape seal ring is subject to gas pressure, C shape seal ring is open configuration, and fitting with inboard wall of cylinder block, large (little) piston packing bottom land respectively in the two ends of opening, reaches the effect of sealing.
Cylinder sleeve is provided with cushion pad by one end that the holding of one-level guide sleeve is spacing, piston rod is established by one end that the holding of secondary guide sleeve is spacing and is also provided with cushion pad.During the shoulder of the spacing holding of I and II guide sleeve on cylinder sleeve and piston rod, the cushion pad of setting can reduce the collision between it, thus protects I and II guide sleeve, cylinder sleeve and piston rod.
The outer wall that large piston contacts with inboard wall of cylinder block is coated with polytetrafluoroethylene solids oiling agent, the outer wall that small piston contacts with inboard wall of cylinder liner is coated with polytetrafluoroethylene solids oiling agent, the madial wall of one-level guide sleeve and secondary guide sleeve is coated with Molykote.The polytetrafluoroethylene solids oiling agent of spraying can make cylinder body and form anode oxide film and teflon friction pair between (little) piston and dynamic seal ring (rubber seal) greatly; Molykote can make to form anode oxide film and molybdenum disulfide friction pair between cylinder sleeve and one-level guide sleeve, between piston rod and secondary guide sleeve.
The beneficial effect that the present invention compared with prior art has is:
1) synchronism is good
Cylinder of the present invention adopts the technology such as self-lubricating solid, charge flow rate and original volume control, and coefficient multi cylinder synchronism is higher.
2) storage life is long, non-maintaining
Cylinder of the present invention adopts solid lubrication, and avoid the tedious work of maintenance that oil lubrication brings, maintenance, therefore do not need periodic maintenance, storage life is long.
3) good economy performance
Every technical matters that cylinder of the present invention adopts is better, is not very high to the required precision of cylinder, therefore good economy performance.
4) cylinder engine science of the present invention, structure is simple, and with low cost, applied range, can be widely used in the machinery industry using gas as power.
