Abstract
The invention discloses a rapid air inlet hydraulic cylinder, which is applied to the field of hydraulic equipment. The rapid air inlet hydraulic cylinder comprises a cylinder body, a piston rod and an oil supplying controller, wherein the oil supplying controller is arranged on the cylinder body; the inside of the piston rod is hollowed to form a rod inner cavity; the rod inner cavity is communicated with a third oil port; the cylinder body is provided with a first oil port and a second oil port; the rapid air inlet hydraulic cylinder is provided with two oil cavities; under the control of the oil supplying controller, the piston rod can extend rapidly in a non-use stroke through the oil cavity in the rod inner cavity; and stable running of the piston rod can be realized by using the oil cavity corresponding to the second oil port. Compared with the conventional hydraulic cylinder, the rapid air inlet hydraulic cylinder has the advantages that: the speed switching of the hydraulic cylinder in the stroke can be realized without any other auxiliary mechanisms, and the working efficiency is increased.
Description
Technical field
The present invention relates to a kind of oil hydraulic cylinder, especially relate 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, reliability height.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 by valve body or other additional devices are installed, the cost height, and economic benefit is low.
Summary of the invention
At above-mentioned technical problem, the object of the present invention is to provide a kind of quick empty feed liquor cylinder pressure, it advances piston rod fast in non-use stroke, stablize low cruise in using stroke, and is not only simple in structure, with low cost, and the efficient height.
The objective of the invention is to be achieved through the following technical solutions:
A kind of quick empty feed liquor cylinder pressure, comprise piston rod, cylinder body, first and second hydraulic fluid port and oil controller, described first and second hydraulic fluid port all is connected with corresponding oil pocket, wherein, the inside of described piston rod is hollow shape and forms the bar inner chamber, described bar inner chamber is communicated with the 3rd hydraulic fluid port, and the volume of described bar inner chamber is less than the volume of the oil pocket that is connected with second hydraulic fluid port.
Especially, described oil controller is arranged on the cylinder body.
Beneficial effect of the present invention is, the piston rod inside of described quick empty feed liquor cylinder pressure is provided with the bar inner chamber, the bar inner chamber is communicated with the 3rd hydraulic fluid port, when oil hydraulic cylinder is in non-use process, pressure oil is 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, the 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 advance fast in non-use process, stablizes low cruise in the use process, not only simple in structure but also high working efficiency.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of the quick empty feed liquor cylinder pressure of the present invention.
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 refer to shown in Figure 1ly, Fig. 1 is the structural representation of the quick empty feed liquor cylinder pressure of the present invention.In present embodiment, described quick empty feed liquor cylinder pressure comprises cylinder body 1, piston rod 2, 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 described cylinder body 1, described 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 described bar inner chamber 6 is less than the volume of the oil pocket that is connected with second hydraulic fluid port.
Working procedure is as follows: in the time of in non-use stroke, first hydraulic fluid port 3 is communicated with fuel tank, oil controller 7 control fuel tanks are only given bar inner chamber 6 fuel feeding, pressure oil enters 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, this moment, piston rod 2 entered the F.F. state.After piston rod 2 touches load, oil hydraulic cylinder enters the use stroke, oil controller 7 will be controlled 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, the oil chamber volume that cause is communicated with second hydraulic fluid port 4 is big, 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.
Above-mentioned quick empty feed liquor cylinder pressure has been realized the conversion of piston rod 2 speed in stroke and the non-use stroke by the optimization of this body structure of oil hydraulic cylinder, 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.
Claims (2)
