Abstract
The utility model discloses a quick air-intake hydraulic cylinder applied to the field of hydraulic equipment, which comprises a cylinder body, a piston rod, and an oil supply controller arranged on the cylinder body. The interior of the piston rod is hollow and is formed as the core space of the piston rod. The core space of the piston rod is communicated with a third oil port. The cylinder body is provided with a first oil port and a second oil port. The quick air-intake hydraulic cylinder is provided with two oil chambers. Under the control of the oil supply controller, the piston rod can quickly stretch out through the oil chambers in the core space of the piston rod during the non-use stroke. Meanwhile, the stable operation of the piston rod can be realized through the oil chamber provided corresponding to the second oil port. Compared with a conventional hydraulic cylinder, the speed conversion of the above quick air-intake hydraulic cylinder during a stroke can be realized without other attachment mechanisms. Therefore, the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, especially relates to a kind of quick empty feed liquor cylinder pressure.
Background technique
In industrial control procedure, a large amount of hydraulic control systems of using, wherein, oil hydraulic cylinder is the core parts of hydraulic control system.Oil hydraulic cylinder is a kind ofly can change hydraulic pressure into mechanical energy, makes machinery realize the device of linear reciprocating motion or swing, its transmission stable working, and reliability is high.But when oil hydraulic cylinder load-bearing than heavy load the time, because thrust is directly proportional with effective work area, its cylinder diameter is also just bigger accordingly, and this just makes piston rod stretch out the slow of change.The piston rod of traditional oil hydraulic cylinder is advanced slower in non-use stroke, loses time, and manufacturing efficiency is low; The production needs be can't agree with, and the oil hydraulic cylinder that production needs, not only complex structure agreed with through valve body or other additional devices are installed; Cost is high, and economic benefit is low.
The model utility content
To above-mentioned technical problem, the purpose of the utility model is to provide a kind of quick empty feed liquor cylinder pressure, and it advances piston rod fast in non-use stroke, in using stroke, stablizes low cruise, and is not only simple in structure, with low cost, and efficient is high.
The purpose of the utility model is to realize through following technological scheme:
A kind of quick empty feed liquor cylinder pressure; Comprise piston rod, cylinder body, first and second hydraulic fluid port and oil controller; Said first and second hydraulic fluid port all is connected with corresponding oil pocket, and wherein, the inside of said piston rod is hollow shape and forms the bar inner chamber; Said bar inner chamber is communicated with the 3rd hydraulic fluid port, and the volume of said bar inner chamber is less than the volume of the oil pocket that is connected with second hydraulic fluid port.
Especially, said oil controller is arranged on the cylinder body.
The beneficial effect of the utility model does, the piston rod set inside of said quick empty feed liquor cylinder pressure has the bar inner chamber, and the bar inner chamber is communicated with the 3rd hydraulic fluid port; When oil hydraulic cylinder was in non-use process, pressure oil was full of the bar inner chamber rapidly, because bar inner chamber compression area is little; Piston rod obtains motion speed faster, when oil hydraulic cylinder is in the use process, and second hydraulic fluid port incoming pressure oil; Because the oil pocket area of second hydraulic fluid port is greater than the oil pocket area of the 3rd hydraulic fluid port, pressure oil is big to the active force of piston rod, and piston rod will be stablized low cruise; Than conventional cylinder; It can make piston rod in non-use process, advance fast, in the use process, stablizes low cruise, not only simple in structure but also high working efficiency.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the quick empty feed liquor cylinder pressure of the utility model.
Among the figure:
1, cylinder body; 2, piston rod; 3, first hydraulic fluid port; 4, second hydraulic fluid port; 5, the 3rd hydraulic fluid port; 6, bar inner chamber; 7, oil controller.
Embodiment
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the quick empty feed liquor cylinder pressure of the utility model.In present embodiment, said quick empty feed liquor cylinder pressure comprises cylinder body 1, piston rod 2, and piston rod 2 is enclosed within the inner chamber of cylinder body 1; Offer first hydraulic fluid port 3 and second hydraulic fluid port 4 on the said cylinder body 1; Said piston rod 2 inside are hollow shape and form bar inner chamber 6, and bar inner chamber 6 is communicated with the 3rd hydraulic fluid port 5, and oil controller 7 is arranged on the cylinder body 1; Control is to the fuel feeding of hydraulic fluid port, and the volume of said bar inner chamber 6 is less than the volume of the oil pocket that is connected with second hydraulic fluid port.
Working procedure is following: in the time of in non-use stroke; First hydraulic fluid port 3 is communicated with fuel tank, and oil controller 7 control fuel tanks are only given bar inner chamber 6 fuel feeding, and pressure oil gets into bar inner chamber 6 through the 3rd hydraulic fluid port 5; Because bar inner chamber 6 volumes are little; So pressure oil will be full of bar inner chamber 6 rapidly, just promote piston rod 2 subsequently and advance fast, piston rod 2 gets into the F.F. states at this moment.After piston rod 2 touched load, oil hydraulic cylinder got into and uses stroke, oil controller 7 will control fuel tank to first hydraulic fluid port 3 and 5 mouthfuls of oil-breaks of the 3rd oil; Second hydraulic fluid port 4 replaces the 3rd hydraulic fluid port 5 to feed pressure oil; Cause is big with the oil chamber volume that second hydraulic fluid port 4 is communicated with, and the effective work area of pressure oil is also big, so piston rod 2 will obtain enough big thrust; Piston rod 2 is stablized low cruise, reaches job requirement.
The optimization implementation of above-mentioned quick empty feed liquor cylinder pressure through this body structure of oil hydraulic cylinder the conversion of piston rod 2 speed in stroke and the non-use stroke; Piston rod 2 is advanced in non-use stroke fast; In using stroke, stablize low cruise, improved the working efficiency and the stability of oil hydraulic cylinder.
