Abstract
The utility model provides a pressure boost hydro-cylinder, including master cylinder and auxiliary cylinder, the rodless chamber of master cylinder is equipped with first oil inlet, the master cylinder has the pole chamber to be equipped with first oil return opening, the rodless chamber of auxiliary cylinder is equipped with the second oil inlet, the auxiliary cylinder has the pole chamber to be equipped with the second oil return opening, first oil inlet with second oil return opening intercommunication. The utility model discloses a theory of operation does: when the main oil cylinder works, the pump firstly supplies oil to the auxiliary oil cylinder through the second oil inlet, and the piston of the auxiliary oil cylinder presses the oil in the auxiliary oil cylinder into the first oil inlet from the second oil return port, so that the oil is supplied to the main oil cylinder, and the piston rod of the main oil cylinder is pushed to move; the auxiliary oil cylinder indirectly supplies oil to the main oil cylinder, the pressure of the main oil cylinder can be improved only by selecting the low-pressure pump, and the cost is reduced.
Description
Technical Field
The utility model relates to an hydro-cylinder technical field specifically is a pressure boost hydro-cylinder.
Background
The oil cylinder is a hydraulic actuator which converts hydraulic energy into mechanical energy and makes linear reciprocating motion (or swinging motion). The reciprocating motion device has simple structure and reliable work, can avoid a speed reducer when the reciprocating motion is realized, has no transmission clearance, and moves stably, thereby being widely applied to hydraulic systems of various machines.
In order to increase the working pressure of the oil cylinder, a high-pressure pump is generally adopted for supplying oil, and the cost is higher.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problem that the oil cylinder for supplying oil by adopting a high-pressure pump is high in cost is solved.
The utility model provides a pressure boost hydro-cylinder, including master cylinder and auxiliary cylinder, the rodless chamber of master cylinder is equipped with first oil inlet, the master cylinder has the pole chamber to be equipped with first oil return opening, the rodless chamber of auxiliary cylinder is equipped with the second oil inlet, the auxiliary cylinder has the pole chamber to be equipped with the second oil return opening, first oil inlet with second oil return opening intercommunication.
The utility model discloses a theory of operation does: when the main oil cylinder works, the pump firstly supplies oil to the auxiliary oil cylinder through the second oil inlet, and the piston of the auxiliary oil cylinder presses the oil in the auxiliary oil cylinder into the first oil inlet from the second oil return port, so that the oil is supplied to the main oil cylinder, and the piston rod of the main oil cylinder is pushed to move; the auxiliary oil cylinder indirectly supplies oil to the main oil cylinder, the pressure of the main oil cylinder can be improved only by selecting the low-pressure pump, and the cost is reduced.
Furthermore, the auxiliary oil cylinder is arranged on the body of the main oil cylinder. So that the utility model discloses the structure is compacter.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a cross-sectional view of the present invention;
in the figure: 1. a master cylinder; 2. an auxiliary oil cylinder; 11. a first oil inlet; 12. a first oil return port; 21. a second oil inlet; 22. and a second oil return port.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model relates to a booster cylinder, which comprises a main cylinder 1 and an auxiliary cylinder 2, wherein the auxiliary cylinder 2 is arranged on the body of the main cylinder 1; as shown in fig. 2, a rodless cavity of the main oil cylinder 1 is provided with a first oil inlet 11, a rod cavity of the main oil cylinder 1 is provided with a first oil return port 12, a rodless cavity of the auxiliary oil cylinder 2 is provided with a second oil inlet 21, a rod cavity of the auxiliary oil cylinder 2 is provided with a second oil return port 22, and the first oil inlet 11 is communicated with the second oil return port 22.
The utility model discloses a theory of operation does: when the main oil cylinder 1 works, the pump firstly supplies oil to the auxiliary oil cylinder 2 through the second oil inlet 21, and the piston of the auxiliary oil cylinder 2 presses the oil in the auxiliary oil cylinder 2 into the first oil inlet 11 from the second oil return opening 22, so that the main oil cylinder 1 is supplied with oil, and a piston rod of the main oil cylinder 1 is pushed to move; the auxiliary oil cylinder 2 is used for indirectly supplying oil to the main oil cylinder 1, the pressure of the main oil cylinder 1 can be improved only by selecting a low-pressure pump, and the cost is reduced.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
