Description
Technical field
The present invention relates to a kind of devices that can detect bolt tight condition, can especially identify the pad of bolt looseness state
Circle.
Background technology
Bolt looseness is the common phenomenon of engineering field, and current detection method mainly has corner monitoring method, screw-down torque
The methods of detection method, bolt axial force Sensor monitoring and pressure disc Sensor monitoring, wherein related to the present invention is pressure
Power washer sensor method.Existing pressure disc sensor can be divided into two classes：One kind is gasket type load cell, generally
It is made of components such as annular elastomeric, shell, strain gauge, pigtail splices, strain gauge usually constitutes Huygens's electric bridge, has four to draw
The characteristics of line, the detection device of rear end are strain gauge dynamometer, this kind of pressure disc sensor be large carrying capacity, precision it is high,
Can continuous monitoring bolt prefastening load situation of change, but due to size is big, thickness is thick, the influence to bolt fastening structure compared with
Greatly, it is high to add use cost, it is difficult to which large-scale application is usually applicable only to small-scale or provisional testing inspection field.
Another kind of is diaphragm pressure washer, is generally printed by film substrate and conductive coating, its main feature is that thickness is thin, cost
It is low, but bearing capacity is also small simultaneously, and stability, repeatability and environmental suitability etc. are poor, are usually applicable only to robot
The fields such as sense of touch detection, consumer electronics.
Invention content
In order to overcome existing pressure disc sensor bearing capacity and thickness, accuracy of detection and use cost it
Between contradiction, the present invention provides a kind of washer arrangement that can detect bolt looseness, and not only bearing capacity is very big for the washer, and
And thinner thickness, compact dimensions, common plain washer can be substituted and used.In addition, common plain washer is compared, it is of the present invention
Washer arrangement, which not only has, actively loosens detectability, also has certain passive anti-loose ability, due to being based on switching value,
Use cost is low, and stability, repeatability and good environmental adaptability are very suitable for large-scale application.
The technical solution adopted by the present invention to solve the technical problems is：A kind of washer arrangement of detection bolt looseness, by
The components compositions such as saucer washer, fixed shell, detection contact, sensing element, adjusting screw, lead and detection module.Dish
Washer has two panels, opposite to be stacked together, and is connect with fixed shell in outer edge；What saucer washer stacked relatively is formed on one side
Groove；Detection contact is placed in the groove of saucer washer, the other end for detecting contact is extend into fixed shell and sensitivity member
Part contacts；The back of sensing element is equipped with adjusting screw.Adjusting screw is used to adjust the sensitivity of sensing element, can be to difference
Bolt tightness respond.When bolt is tightened, the gap of saucer washer inner ring becomes smaller, detection trigger contact, transmits
To after sensing element, signal is tightened in sensing element generation；Conversely, when bolt looseness, the gap of saucer washer inner ring becomes larger, release
Contact is detected, after being transmitted to sensing element, sensing element, which generates, loosens signal, and the sensing element generates signal and connects by lead
It is connected in detection module.
The invention has the advantages that using beadlike form, easy for installation, large carrying capacity, compact-sized, size is small,
Bolt arrangement is not destroyed, in addition to can be with the elastic state of active detecting bolt, used saucer washer also has preferable passive
Anti-loosing effect.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is the schematic diagram of one embodiment of the present invention.
Fig. 3 is the schematic diagram of second embodiment of the present invention.
1, saucer washer in figure, 2, fixed shell, 3, detection contact, 4, sensing element, 5, adjustment stud, 6, lead, 7,
Detection module.
Specific implementation mode
In preferred embodiment shown in Fig. 1, fixed shell（2）It is ring-like, two saucer washers（1）It is placed by nesting
In fixed shell（2）In, detect contact（3）One end be placed on two saucer washers（1）Between groove in, detect contact
（3）The other end reach in fixed shell（2）, with sensing element（4）Contact adjusts stud（5）Positioned at sensing element（4）The back of the body
Portion.In this example, sensing element（4）Touch-switch is selected, after bolt is tightened, touch-switch is connected, and after bolt looseness, is touched
Switch disconnects, and touch-switch passes through lead（6）It is connected to detection module（7）.
In preferred embodiment shown in Fig. 2, fixed shell（2）It is square, two saucer washers（1）With fixed shell
（2）By being welded together, contact is detected（3）One end be placed on two saucer washers（1）Between groove in, detection
Contact（3）The other end reach in fixed shell（2）, with sensing element（4）Contact adjusts stud（5）Positioned at sensing element（4）
Back.In this example, sensing element（4）Touch-switch is selected, after bolt is tightened, touch-switch is connected, after bolt looseness,
Touch-switch disconnects, and touch-switch passes through lead（6）It is connected to detection module（7）.
