Detailed description of the invention
Seeing Fig. 1, Fig. 2, in the present embodiment, the version of automobile clutch air-leakage test inflation mechanism is:
Air-leakage test inflation mechanism is on pull bar 10, from the top rod end of pull bar 10, connects from top to bottom and coaxially pacifies
Equipped with each sealing ring, being the lower sealing ring 5 of upper sealing ring 2, middle sealing ring 4 respectively, upper sealing ring 2 utilizes pull bar end cap 1 solid
Surely being arranged on the top of pull bar 10, middle sealing ring 4 and lower sealing ring 5 are axially movable on pull bar 10, lower sealing ring 5
Support is in fixing ring seat 9, and fixing ring seat 9 is fixedly installed in the setting height of pull bar 10 by elastic cylindrical pin 12, so that
Each sealing ring is maintained in clutch barrel chamber.
Sealing ring 3a it is pressed with, at middle sealing ring 4 and lower sealing ring 5 between the end face of upper sealing ring 2 and middle sealing ring 4
End face between be pressed with lower seal 3b；Upper sealing ring 3a and lower seal 3b are with its outer circumference surface and clutch bowl cavity wall
Form sealing surface, pull pull bar 10 can be formed between each sealing ring moving axially relative, bring the elastic deformation of sealing, from
And realize the function sealed.
The outer circumference surface of middle sealing ring 4 arranges an annular groove 4a along excircle, at middle sealing ring 4, lower sealing ring 5 and fixing
Having through gas injection passage in ring seat 9, gas injection passage end is connected with annular groove 4a, the other end and external gas tube 17 phase
Connect, after completing to seal, implement inflation by gas tube 17 through gas injection passage.
In being embodied as, as it is shown in figure 1, gas injection passage is Vertical Channel in lower sealing ring 5 and fixing ring seat 9, in
It sealing ring is inverted "L" shaped passage.
Between upper sealing ring 2, middle sealing ring 4 and lower sealing ring 5, adjacent end face is to match with male and fomale(M&F), and
Periphery is formed and accommodates upper sealing ring 3a and the seal groove of lower seal 3b respectively.At upper sealing ring 2, middle sealing ring 4 and
Between the adjacent end face of lower sealing ring 5, it is uniformly distributed with three axle springs 18 along the circumference, and is in different from axle spring 18
It is uniformly distributed with three axial circular pins 15 on position along the circumference, plays compressing sealing ring with axle spring 18 and axial circular pin 15
During realize the directional stability of thrust in the linearly increasing of thrust and compaction process.
In the present embodiment, the axially driving structure of pull bar 10 is set, is to be drawn by transit joint 7 with the piston rod in cylinder 16
Dynamic pull bar 10, cylinder 16 is fixedly installed on connecting plate 8 and base plate 11 by cylinder supports bar 6.
After automobile clutch 13 is fixed on upper sealing ring 2, it is made to pull downward on pull bar 10, pull bar 10 to cylinder 16 ventilation
Being connected by pull bar end cap 1 and bolt of cover 14 with upper sealing ring 2, at this moment pull bar 10 can drive upper sealing ring 2 to move downward,
Upper sealing ring 2 extrudes the upper sealing ring 3a that is disposed below, and band disorder of internal organs sealing ring 4 moves downward, and middle sealing ring 4 to
Lower motion can drive again and be arranged on lower seal 3b being positioned at lower section outside it and move downward, and extrudes lower sealing ring 5, by solid
Determine ring seat 9 and stop moving downward of lower sealing ring 5.
Pull bar 10 continues to move downward under the effect of cylinder 16, at upper sealing ring 2, middle sealing ring 4 and lower sealing ring 5
Under extruding, upper sealing ring 3a and the compacted expansion of lower seal 3b, thus with the inner surface of workpiece, i.e. clutch barrel chamber is interior
Sidewall forms gluing, sealing.When after the sealing ring inner surface gluing, sealing completely with workpiece, at the outer circumference surface of middle sealing ring 4
And forming the little space including annular groove 4a between the medial wall of clutch barrel chamber, automobile clutch barrel chamber is passed through in this little space
Medial wall on through hole be connected with automobile clutch.
Now, being inflated by gas tube and gas injection passage, compressed air is by the through hole on automobile clutch into the barrel chamber sidewall
Inside entrance automobile clutch, it is achieved the inflation to automobile clutch, subsequently, air-leakage test is carried out.
After completing air-leakage test, in cylinder piston rod be raised above drive pull bar 10 move upward, make upper sealing ring 2,
Distance between middle sealing ring 4 and lower sealing ring 5 three widens, and releases upper sealing ring and the compression of lower seal, by automobile
Clutch departs from from upper sealing ring 2, completes automobile clutch and separates with mechanism.
