In order to solve the above technical problems, the present invention provides a kind of engine valve discone antenna surface air-tightness detection device, it is special
Sign is, including turns the connecting rod that main shaft is connected with platform, is provided with spring below the connecting rod, the spring is connected with compact heap
Connect, the compact heap is in contact with valve.
Foregoing engine valve discone antenna surface air-tightness detection device, it is characterized in that, regulation is provided with around the connecting rod
Set.
Foregoing engine valve discone antenna surface air-tightness detection device, it is characterized in that, regulation is provided with outside the compact heap
Mother, the female side of regulation are provided with locking nut.
Foregoing engine valve discone antenna surface air-tightness detection device, it is characterized in that, the compact heap side is provided with level pressure
Pin.
Foregoing engine valve discone antenna surface air-tightness detection device, it is characterized in that, the valve is arranged on valve seating.
Foregoing engine valve discone antenna surface air-tightness detection device, it is characterized in that, described turns to be connected with main shaft and shakes
Arm handle.
The beneficial effect that the present invention is reached：Valve structure of the detecting device of the present invention is simple, easy to operate, suitable high-volume
Product checking.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in figure 1, a kind of engine valve discone antenna surface air-tightness detection device, including with platform turn the company that main shaft is connected
Extension bar 1, described turns to be connected with rocker handle on main shaft.The lower section of connecting rod 1 is provided with spring 3, the spring 3 and compact heap
5 are connected, and the compact heap 5 is in contact with valve 8.The valve 8 is arranged on valve seating.It is provided with around the connecting rod 1
Adjusting set 2.The outside of compact heap 5 is provided with regulation mother 4, and female 4 sides of regulation are provided with locking nut 6.The compact heap 5 one
Side is provided with level pressure pin 7.
Operating method：The device with repacking table drill main shaft be connected, when being rotated down bench drill rocker handle, by mounted in
Connecting rod 1 on table drill main shaft, compact heap 5 is in contact with tested valve 8, continue to rotate bench drill handle, be enclosed on compact heap 5
Spring 3 compressed, until the level pressure pin 7 on compact heap 5 is in contact with regulation female 4.At this moment the power acted on tested valve 8
For a metastable numerical value, the big I of power is determined by adjusting mother 4.Numerical value available standards, which are dispelled, piles up on regulation mother 4
To determine.The decrement of spring 3 can be fixed once setting with locking nut 6.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
