Can realize the output of great load, can use in the occasion of the big load of needs, and easy operation, the security is high.
Description
Technical field
The utility model relate to a kind of pressurizing cylinder, belongs to oil cylinder technical field.
Background technique
Hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion (or oscillating motion) by oil hydraulic cylinder.Its structure is simple, reliable operation.When realizing to-and-fro motion with it, can speed reducer be removed from, and there is no drive gap, stable movement, therefore be used widely in the hydraulic system of various machinery.
But existing oil hydraulic cylinder is normally driven by single supercharging mode, and the load of output is less, cannot meet and beat load requirements.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of pressurizing cylinder, can realize the output of larger load, can use needing the occasion of large load, and simple to operate, and Security is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of pressurizing cylinder, comprise master cylinder, first piston and the second piston is provided with in described master cylinder, the lower end of described second piston is provided with the first piston bar stretching out described master cylinder lower surface, hydraulic oil is filled with in master cylinder between described first piston and the second piston, master cylinder body above described first piston is provided with suction port, the side of described master cylinder is also provided with the secondary cylinder with described suction port UNICOM, the second piston rod is provided with in described secondary cylinder, the upper end portion of described master cylinder is provided with the 3rd piston and passes described first piston and the 3rd piston rod stretched to above described second piston, described secondary cylinder is also provided with the breathing pipe with described master cylinder top UNICOM.
Aforesaid a kind of pressurizing cylinder, is characterized in that: the bottom of described master cylinder is also provided with the muffler with described suction port UNICOM.
Aforesaid a kind of pressurizing cylinder, is characterized in that: the upper end of described secondary cylinder arranges briquetting, is provided with spring between described briquetting and described second piston.
The beneficial effects of the utility model are: by after suction port injecting gas, first piston is driven to promote downwards, by hydraulic oil transmission the second piston and first piston bar be pushed to downwards and to a certain degree stop afterwards, gas continues to enter secondary cylinder, by the second piston rod upwardly after, gas returns master cylinder, 3rd piston and the 3rd piston rod are promoted downwards, in the cavity of the 3rd piston press-in first piston 1, by hydraulic oil transmission, first piston bar is promoted, get to the output of pressure.
Accompanying drawing explanation
Fig. 1 is the plan view of a kind of pressurizing cylinder of the utility model;
Fig. 2 is the sectional view of a kind of pressurizing cylinder of the utility model;
Fig. 3 is the sectional view of a kind of pressurizing cylinder loaded state of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described further.
As shown in Figure 1-Figure 3, a kind of pressurizing cylinder, comprise master cylinder 1, first piston 11 and the second piston 21 is provided with in described master cylinder 1, the lower end of described second piston 21 is provided with the first piston bar 12 stretching out described master cylinder 1 lower surface, hydraulic oil 8 is filled with in master cylinder 1 between described first piston 11 and the second piston 21, master cylinder 1 cylinder body above described first piston 11 is provided with suction port 3, the side of described master cylinder 1 is also provided with the secondary cylinder 2 with described suction port 3 UNICOM, the second piston rod 22 is provided with in described secondary cylinder 2, the upper end portion of described master cylinder 1 is provided with the 3rd piston 13 and passes described first piston 11 and the 3rd piston rod 14 stretched to above described second piston 21, described secondary cylinder 2 is also provided with the breathing pipe 4 with described master cylinder 1 top UNICOM.
By after suction port injecting gas, first piston is driven to promote downwards, by hydraulic oil transmission the second piston and first piston bar be pushed to downwards and to a certain degree stop afterwards, gas continues to enter secondary cylinder, by the second piston rod upwardly after, gas returns master cylinder, 3rd piston and the 3rd piston rod are promoted downwards, in the cavity of the 3rd piston press-in first piston 1, by hydraulic oil transmission, first piston bar is promoted, get to the output of pressure.
The bottom of described master cylinder 1 is also provided with the muffler 5 with described suction port 3 UNICOM, and the upper end of described secondary cylinder 2 arranges briquetting 6, is provided with spring 7 between described briquetting 6 and described second piston 21.During unloading, suction port stops gas transmission, and gas is returned by muffler 5, and the second piston 21 in secondary cylinder 2 is resetted by spring 7, and oil cylinder realizes unloading.
In sum, a kind of pressurizing cylinder that the utility model provides, can realize the output of larger load, can use needing the occasion of large load, and simple to operate, and Security is high.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
