Description
Technical field
The utility model is related to the mechanisms that a kind of auxiliary carries out the muffler of automobile exhaust system gas leakage detection, belong to gas
Close property detection device technical field.
Background technology
Muffler in automobile exhaust system in a pre-installation will be detected its air-tightness, need to be by muffler before detection
Nozzle is blocked to seal, and traditional ferrule is blocked using artificial, and it is slow and easy because blocking not tight to block speed
Gas leakage is generated, the testing result of air-tightness is influenced.
Utility model content
To solve defect of the existing technology, the purpose of this utility model is to provide that a kind of sealing effect is good, speed is fast
For muffler of automobile exhaust system gas leakage detection sealing mechanism.
The technical solution of the utility model is：A kind of sealing mechanism for muffler of automobile exhaust system gas leakage detection,
Include the cope plate being slidably connected with guide rod and lower template, cylinder is located on the cope plate, the piston-rod end of the cylinder
Lower template is connected, limited block is fixed on guide rod lower part, and lower template is located at below limited block, on the cope plate and lower template respectively
Upper mold is installed and blocks rubber block and lower die closure rubber block, the upper mold blocks rubber block and lower die blocks rubber block and sets relatively
It sets.
The cope plate is slidably connected by linear bearing and guide rod.
The upper mold blocks rubber block and lower die to block rubber block section be semicircle, and two described semicircular are opened
Mouth is opposite.
Guide rod bottom end connecting bottom board.
Lower template is bolted in the piston-rod end.
The cope plate and lower template be it is rectangular, guide rod be four, four guide rods be connected to cope plate and
On four angles of lower template.
The utility model has the beneficial effects that：Two sealing devices are staggered relatively, are respectively used to sealing muffler both ends
Nozzle, in use, cylinder is ventilated, piston rod drives upper mold to block rubber block and lower die closure rubber block movement, and nozzle is close
Envelope, seal operation are easy, quick.
Description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model side view；
Fig. 3 is the utility model sectional side view；
Fig. 4 is the utility model vertical view.
Reference numeral is as follows in figure：1, guide rod, 2, cope plate, 3, lower template, 4, linear bearing, 5, cylinder, 6, limited block,
7, upper mold blocks rubber block, 8, lower die block rubber block, 9, bottom plate, 10, bolt.
Specific implementation mode
1-4 is described further the utility model below in conjunction with the accompanying drawings：
It is a kind of for muffler of automobile exhaust system gas leakage detection sealing mechanism, include be slidably connected with guide rod 1 it is upper
Template 2 and lower template 3, cylinder 5 are located on the cope plate 2, and the piston-rod end of the cylinder 5 connects lower template 3, limited block
6 are fixed on 1 lower part of guide rod, and lower template 3 is located at 6 lower section of limited block, upper mold is separately installed in the cope plate 2 and lower template 3
It blocks rubber block 7 and lower die blocks rubber block 8, the upper mold blocks rubber block 7 and lower die blocks rubber block 8 and is oppositely arranged.
The cope plate 2 is slidably connected by linear bearing 4 and guide rod 1.
It is semicircle that the upper mold, which blocks rubber block 7 and 8 section of lower die closure rubber block, and two described semicircular
Opening is opposite.
1 bottom end connecting bottom board 9 of the guide rod.
The piston-rod end connects lower template 3 by bolt 10.
The cope plate 2 and lower template 3 are rectangular, and guide rod 1 is four, and four guide rods 1 are connected to upper mold
On four angles of plate 2 and lower template 3.
It in seal operation, needs two sealing devices are staggered relatively to be used cooperatively, is respectively used to sealing muffler both ends
Nozzle, in use, cylinder 5 is ventilated, piston rod drives lower template 3 and lower die to block rubber block 8 and moves up, instantly molding
Stifled rubber block 8 is blocked stopping movement when being moved to 6 lower end of limited block, at this point, cylinder 5, cope plate 2 and upper mold block rubber
Block 7 is moved down along guide rod 1, until upper mold blocks rubber block 7 and fitted closely with lower die closure rubber block 8, by disappearing between the two
Sound device ferrule is lived, after the ferrule at muffler both ends, using airtight instrument or gas air tightness detection equipment to muffler
Air-tightness be detected.The utility model is easy to the seal operation to muffler, quick, and sealing effect is good, it is ensured that gas
Close property testing result it is accurate.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into modification.
