The course of work and principle：The outer surface most bottom of the slot bottom of lower arcuate slot 57 and cylindrical frame (70) when original state
Portion is located at same straight line, and when using the detection fixture, one end of staff's bellows first is placed on lower arcuate slot 57,
And flicking down, at this moment first pressure sensor 53 experiences pressure value, and transmits the signal in controller 11, this time control
Device 11 processed controls the starting of the second cylinder 59, drives the upper arc groove 58 on movable block 52 to compress bellows downwards, works as first pressure
When sensor 53 is experienced pressure value and is greater than the set value, indicate that bellows has compressed, at this time the record of controller 11 first first
The data that infrared range-measurement system 56 measures, twice of the distance of the slot bottom of lower arcuate slot 57 to 51 upper surface of fixed block and the data
It is exactly the diameter of bellows, then controller 11 subtracts half jin of cylindrical frame (70) radius of bellows and record and is somebody's turn to do
Data are A, and controller 11 controls motor 60 and rotates, and are stopped after driving elevator 3 to move down the distance of A, this when cylinder
The axis of 70 axis of shape frame and bellows will be on same straight line, after the completion, and it is dynamic that controller 11 controls the first cylinder 2
Make to drive cylindrical frame 70 mobile to the direction of bellows, when bellows touches elasticity pressing piece 78, elasticity pressing piece 78
It can snap fit onto the ripple gap of bellows, bellows can will can not be moved to the right with normal movement to the left, be worked as ripple at this time
When pipe contacts top plate 75 and continues to be moved to the left, spring 75 will withstand top plate 75 upwards, and such second pressure sensor 76 will
The pressure that bellows can be perceived, when exceeding setting value, the first cylinder 2 stops, and at this moment controls electromagnetic gas valve 12 and opens, makes gas
Body pours in aeration tank 74, then enters in bellows into circular through hole 79 excessively, since elasticity presses the snap action of piece 78,
In the moment that electromagnetic gas valve 12 is opened, the stability of bellows ensure that, after completing air-leakage test, manually turn unlock rod
815 make to solve the tightening of lock ring 81, make to move in the inside aeration tank 74 of driving cog bar 82 in this way, drive driving wheel 83 to rotate, in turn
It drives master bevel gear 83 to rotate, and then rotates drive rod 85 under the drive from bevel gear 86, and then make 80 turns of the first screw rod
It is dynamic to drive sliding shoe 810 downwards, and then hinge bar 813 is driven to pull downward on elasticity pressing piece 78, it is detached from elasticity pressing piece 78
The ripple gap of bellows, and then bellows is made normally to remove aeration tank 74, after removal, motor 60 drives the movement of elevator 3 to make
The slot bottom of lower arcuate slot 57 and the outer surface bottommost of cylindrical frame (70) are located at same straight line again, and whole process effectively saves
It saves labor costs, accelerates clamping efficiency and precision, reduce testing cost.
Based on above-mentioned, using device for detecting airtightness of corrugated tube of the invention detection fixture, for the wave of different size
Line pipe, when carrying out bellows air-leakage test, operator only needs for bellows to be placed on clamping device, machine to be held
After structure clamps, elevating mechanism automatic adjustment makes the center of bellows core and aeration tank be located along the same line, then in cylinder
Inflation mechanism is closely connect with bellows under drive, elasticity pressing piece is automatically by ripple pipe clamp, after detection, operator
Member turns the unlock rod in unlocking mechanism and completes unlocking motion, which effectively saves human cost, accelerates clamping efficiency and essence
Degree reduces testing cost.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.Institute
Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
