The side being connect with alignment pin on block is equipped with sealing surface.This automobile exhaust pipe sealing detection is deposited in use with plug
In following deficiency：It is sealed by the end face opposing crimp of the sealing surface and automobile exhaust pipe nozzle that then pass through plug ontology,
When detecting the quantity of gas leakage in automobile exhaust pipe, gas is easy to leak from automobile exhaust pipe nozzle, causes to judge partial automobile by accident
Exhaust pipe is unqualified, and percent defective is higher；And the sealing surface requirement on machining accuracy of plug ontology is high, causes production cost
It is high.
Utility model content
Problem to be solved in the utility model is to provide a kind of automobile exhaust pipe sealing detection plug, it can be solved
When detecting the quantity of gas leakage in automobile exhaust pipe, gas is easy to leak from automobile exhaust pipe nozzle, causes to judge partial automobile by accident
Exhaust pipe is unqualified, the problem that percent defective is higher and production cost is high.
To solve the above-mentioned problems, the technical solution adopted in the utility model is：This automobile exhaust pipe sealing detection is used
Plug, includes plug ontology and power cylinder, and the plug ontology is equipped with coupling block and stretches into the positioning of automobile exhaust pipe nozzle
Axis pin, is coated with motion bar in the alignment pin, and described motion bar one end passes through the coupling block and the power cylinder
Piston rod connects, and the other end is equipped with limiting stand raised outward, and set is equipped between the limiting stand and the alignment pin
Elastic sealing element on the motion bar.
With in plug technical solution, more specific technical solution can also be above-mentioned automobile exhaust pipe sealing detection：It is described
The outside of elastic sealing element is abutted against with automobile exhaust inside pipe wall.
Further, the elastic sealing element is in annulus cylindricality, the length of L, internal diameter d, outer diameter D, internal diameter d < long
Spend L < outer diameter Ds.
Further, the motion bar is connect by screw thread with the piston rod of the power cylinder, the coupling block with it is described
The cylinder body of power cylinder is fixedly connected.
Further, the elastic sealing element is made of rubber material.
By adopting the above-described technical solution, the utility model has the advantages that compared with prior art：
1, the utility model is coated with motion bar in alignment pin, and motion bar one end passes through the work of coupling block and power cylinder
Stopper rod connects, and the other end is equipped with limiting stand raised outward, is equipped between limiting stand and alignment pin and is sleeved on motion bar
On elastic sealing element.When being sealed property detects, start power cylinder, the piston rod retraction of power cylinder drives motion bar to dynamic
Power cylinder direction move, after so that elastic sealing element is squeezed cross section increase, swelling between automobile exhaust inside pipe wall and motion bar,
Good seal when detecting the quantity of gas leakage in automobile exhaust pipe prevents gas from being leaked from automobile exhaust pipe nozzle, avoids mistake
It is unqualified to sentence automobile exhaust pipe, percent defective is relatively low；And plug ontology requirement on machining accuracy is low, and production cost is low.
2, the outside of elastic sealing element and automobile exhaust inside pipe wall abut against, can be quick after elastic sealing element is squeezed
Swelling prevents gas from leaking between automobile exhaust inside pipe wall and motion bar.Elastic sealing element be in annulus cylindricality, the length of L,
Internal diameter is d, outer diameter D, internal diameter d < length L < outer diameter Ds, and elastic sealing element is made to have enough deflections, ensures good seal.
3, motion bar is connected by the piston rod of screw thread and power cylinder, and coupling block is fixedly connected with the cylinder body of power cylinder, makes
Motion bar and elastic sealing element are convenient for disassembly and assembly, replace and are easy after elastic sealing element abrasion.
