Also including air-leakage detector, described air-leakage detector is connected to accumulator and source of the gas by trachea, described
Source of the gas is for supplying to described air-leakage detector；
Being further fixed on sealing detection on the table to block up and electromagnetic valve, described sealing detection is blocked up for described hydraulic cylinder
Seal；
It is connected by trachea and described sealing detection are stifled on described air-leakage detector.
As the improvement of the present invention, described fixture includes latch segment and the first cylinder, and described first cylinder front end connects
Described latch segment, by latch segment locked hydraulic cylinder described in described first air cylinder driven, described first cylinder is connected by trachea
Described electromagnetic valve.
As a further improvement on the present invention, described electromagnetic valve is connected by trachea with described source of the gas, on described electromagnetic valve
Being connected to the second cylinder by trachea, in the front end of described second cylinder, fixed described sealing detection is blocked up.
Preferred as the present invention, described air-leakage detector is connected to power supply by wire, and described power supply opens with described
Dynamic switch is connected.
Compared with prior art, it is an advantage of the current invention that: by the air-tightness to manual transmission clutch hydraulic cylinder
Automatically detection, effectively solves the product bug that hydraulic cylinder leakage of oil causes, improves the Detection capability of product, assembles at part
Before detect, eliminate fault and reprocess man-hour, improve product quality simultaneously, it is ensured that manual transmission clutch hydraulic cylinder
Safety and reliability in car load.

Detailed description of the invention
With reference to Fig. 1, the embodiment being used for clutch hydraulic cylinder air-tightness automatic detection device in the present invention is done furtherly
Bright.
As it is shown in figure 1, the present embodiment is a kind of for the automatic air-tightness detection device of clutch hydraulic cylinder, include work
Platform 1, workbench has the table top of a level, is provided with positioning seat 2 on table top, for carrying hydraulic cylinder to be detected,
Make it during detection, play not occur to be firmly locked at by hydraulic cylinder on positioning seat, positioning seat is provided with folder
Tool, fixture includes latch segment 3 and the first cylinder 4, and latch segment one end is fixed on the first cylinder, and the other end is erected at positioning seat
Top, when hydraulic cylinder is put on positioning seat and put in place, is pressed by under the first air cylinder driven latch segment, by hydraulic locking cylinder in location
On seat.
It is that this is by an air-leakage test to hydraulic cylinder internal injection gas on the detection bubble-tight process nature of hydraulic cylinder
Instrument 5 realizes, and air-leakage detector is that special air-tight detects device, by squeezing into air in hydraulic cylinder, detects hydraulic pressure
The air-tightness of cylinder is the most qualified.This air-leakage detector 5 is also secured on workbench 1, on air-leakage detector by trachea even
Then accumulator 6, source of the gas 7 and a sealing detection block up 8, and the effect that sealing detection is blocked up is can be used to the oil of sealing fluid cylinder pressure
Pipe pipeline, to its internal transmission compressed air, the oil connection gas leakage on hydraulic cylinder, acting on of accumulator 6 when preventing from detecting
In the pressure differential detection tank as air-leakage detector, air-leakage detector needs to squeeze into air pressure to hydraulic cylinder and accumulator simultaneously
Detection pressure reduction, thus judge testing result.Source of the gas is for the first cylinder in the present embodiment, the second cylinder 9, air-leakage test
Instrument supplies.
Owing to having tappet on hydraulic cylinder, when hydraulic cylinder air pressure inside rises, tappet can be promoted to stretch out to outside, in order to
Preventing from tappet from excessively stretching out generation to damage, the side of positioning seat is provided with limiting plate 10, this limiting plate can limit tappet
Range.Opposite side at positioning seat is provided with pneumatic on-off valve 11, when hydraulic cylinder is fixed on positioning seat, and hydraulic cylinder
Now mutually touch with pneumatic on-off valve, thus trigger activate switch valve, and signal is passed to by holding wire the startup of outside
Switch 12.Further comprises electromagnetic valve 13, electromagnetic valve is connected by trachea with above-mentioned source of the gas, is connected to by trachea thereon
One cylinder 4 and the second cylinder 9, sealing detection is stifled to be fixed on the second cylinder, by the second air cylinder driven its with the oil on hydraulic cylinder
Pipe joint contacts.Additionally, air-leakage detector is connected to power supply 14 by wire, power supply is connected with described activate switch, by opening
Move switch open or close above-mentioned power supply.
Specific works flow process is as follows:
Hydraulic cylinder is arranged in positioning seat 2, touches pneumatic on-off valve 11, makes activate switch 12 to work, press startup
Switch 12, the first cylinder 4 drives latch segment 3 to be pressed on hydraulic cylinder, the second cylinder 9 drive sealing detection block up 8 with hydraulic cylinder oil pipe
Interface docks, and air-leakage detector 5 is started working and squeezed into setting air pressure to hydraulic cylinder and accumulator respectively, and detection hydraulic cylinder is airtight
Property, qualified after show OK, again press activate switch device and return in situ, air-leakage test process completes.
The above makes the preferred embodiment of the present invention, for the person of ordinary skill of the art without departing from this
On the premise of bright principle, it is also possible to make some modification and improvement, these also should be regarded as protection scope of the present invention.
