Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
Please refer to Fig.1-2, a kind of hydraulic power unit for hydraulically operated fixture oil cylinder, including the first dynamic equipment 11.1,
Two dynamic equipments 11.2, the gas solenoid valve 5 for control cylinder action, the air accumulator 3 for pressure caching, the gas for pressurize
With check valve 2, filter 9 and leakage alarm switch 6 for sensing exterior oil circuit oil leak, one end of gas check valve 2
Shut-off valve 1 is connected, gas connects air accumulator 3, the other end connection gas three elements 4, the gas of air accumulator 3 with the other end of check valve 2
With the other end connection gas solenoid valve 5 of three elements 4, it is dynamic that gas solenoid valve 5 is also respectively connected with the first dynamic equipment 11.1 and second
Power device 11.2, it is dynamic that the first dynamic equipment 11.1 is also respectively connected with leakage alarm switch 6, filter 9, silencer 12, oil cylinder 8 and second
Power device 11.2, filter 9 are also connected with fuel tank 10, and the second dynamic equipment 11.2 is also connected with oil cylinder 8 and filter 9.
Leakage alarm switch 6 is made of measurement bar 6.1, fixing bolt 6.4, fixing bracket 6.2 and travel switch 6.3.Let out
Oil pressure gauge 7 is additionally provided among leakage alarm switch 6 and oil cylinder 8.Gas is 25 ventilation solenoid valves with solenoid valve 2.
The present invention operation principle be：As described in Figure 1：Including the first assistor 11.1, gas solenoid valve 5, air accumulator 3,
Gas check valve 5, filter 9, leakage alarm switch 6.First assistor 11.1 and the second assistor 11.2 provide air pressure conversion
For hydraulic pressure and supercharging executive component；Gas is with solenoid valve 5 as cylinder action control element；Air accumulator 3 caches element as pressure,
Ensure that oil cylinder 8 in clamping process, reduces pressure oscillation caused by air pressure fluctuation；Gas, as pressurize member original paper, is protected with check valve 5
When card input compressed air pressure is decayed suddenly, output oil pressure will not follow unexpected decay；Gas is with three elements 4 as input gas
Purification and input air pressure regulating element；Alarm switch 6 is revealed as exterior oil circuit oil leak sensing element.
Control instruction drive magnetic valve commutates, and compressed air enters the second dynamic equipment 11.2, and the second assistor 11.2 is fuel-displaced
End exports high oil pressure, and high pressure oil promotes fixture oil cylinder 8 to perform pinching action, because compressed air and assistor are constantly in after clamping
On-state, maintains output oil pressure constant（The energy is no longer consumed after compression）；After machining, M order-drivens gas solenoid valve 5
Commutate, compressed air is connected with air in the second dynamic equipment 11.2, and oil pressure disappears.Compressed air connects the first dynamic equipment at the same time
In 11.1, the first dynamic equipment 11.1 input high pressure oil, promotes fixture oil cylinder 8 to perform release action.
Leakage alarm switch 6 is made of measurement bar 6.1, fixing bolt 6.4, fixing bracket 6.2 and travel switch 6.3；Its
Operation principle is：After oil leak occurs in outer clamp oil circuit, assistor push-plate will move forward to extreme position, at this time push-plate with
Measurement bar 6.1 contacts, and measurement bar 6.1 is moved rearwards, and starts travel switch 6.3, and travel switch 6.3 connects alarm signal, with
This realizes output alarm signal function.
For the present invention using compressed air as power source, substitution motor provides the mode of power.It is real by varying piston cylinder diameter ratio
Low pressure is now inputted, exports high oil pressure function（Booster principle）；The present invention is using 4.0-240 assistors as supercharging and gas-liquid
Conversion element, its pressure ratio use 1:7.2, its oil pressure after being pressurized meets oil pressure requirement needed for most hydraulically operated fixtures；
This equipment feature is：Source of the gas is just consumed after assistor action only when the execution of fixture oil cylinder acts, so energy consumption is low, separately
Due to hydraulic oil, only the hydraulic oil in fixture cylinder action just flows, so hydraulic fluid temperature will not be excessive, avoids hydraulic oil newborn
Change problem, hydraulic oil is without periodic replacement.
