The whole efficiency of examination.
The technical scheme is that a kind of catalyst converter air-tightness detection device of offer, including the end being arranged on opposite side
Fixture and aerating device, setting inflation through hole in described end-fixture, side ports of described inflation through hole are filled with described
Device of air connects, and the other end is connected with the fixed part with workpiece end outline to be detected cooperation, and described end-fixture sets
Put the travel mechanism for the linear movement carrying out relatively drawing close by end-fixture described in both sides, described in both sides between end-fixture
It is additionally provided with and lift platform.Preferred as the present invention, described lifting is provided with the arc agreeing with outer wall profile on the downside of workpiece on platform
Shape frame.
Preferred as the present invention, described travel mechanism includes movable stand, and described movable stand is with described end-fixture even
Connect, described movable stand is provided with sinciput cylinder.
Preferred as the present invention, described aerating device is inflator pump.
Preferred as the present invention, described fixed part medial wall is provided with the sealant layer for increasing sealing.
So design is to eliminate the gap between fixed part and catalyst converter, lift-off seal performance.
Preferred as the present invention, described sealant layer is internally provided with and strengthens sealing effect by inflating extended volume
The air bag of fruit.So design makes the sealing of fixed part be lifted with air pressure and be lifted, and completely solves the mistake of air pressure lifting
The problem that in journey, sealing declines.
Preferred as the present invention, described inflation through hole includes first through hole and and the work led to described airbags
The second through hole that part is connected.So it is ensured that inflate simultaneously.
Preferred as the present invention, described first through hole is annular through-hole and the outside being enclosed in described second through hole,
Described first through hole and the central axes of described second through hole.So it is ensured that inflation when air pressure equalisation.
The invention has the advantages that：
The present invention has good airproof performance, the high advantage of testing efficiency.

Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in figure 1, the first embodiment of the present invention includes end-fixture 1 and the aerating device being arranged on opposite side
2, in end-fixture 1 setting inflation through hole 3, inflation through hole 3 side ports be connected with aerating device 2, the other end be connected with and
The fixed part 4 of workpiece end outline cooperation to be detected, end-fixture 1 is provided for carry out relatively both side ends fixture 1
The travel mechanism 5 of the linear movement drawn close, is additionally provided between both side ends fixture 1 and lifts platform 6.Lift and be provided with contract on platform 6
Close the arc frame 7 of outer wall profile on the downside of workpiece.Travel mechanism 5 includes movable stand 8, and movable stand 8 is connected with end-fixture 1, mobile
Sinciput cylinder 9 is provided with frame 8.Aerating device 2 is inflator pump.The concrete setting of fixed part 4 is according to catalyst converter two ends shape
Difference and change, so being exactly to fit design with outline with outline cooperation, be highly important designing points.Mobile
The move mode of mechanism 5 must be linear, could very stable compress catalyst converter so when air pressure is lifted.Mobile
The effect one of mechanism 5 is to clamp catalyst converter, and two is to keep sealing, and this point effect is mainly reflected in gas replenishment process
In, the lifting of catalyst converter internal gas pressure leads to fixed part 4 to move toward both sides, thus leading to sealing to reduce, and travel mechanism 5 is necessary for
Dynamically coordinate this relative movement to move clamping catalyst converter again and ensure sealing.Same is that aerating device 2 is permissible
It is substituted for charging device, such as water pump etc..
As shown in Figure 2 to Figure 3, the second embodiment of the present invention includes being arranged on the end-fixture 1 of opposite side and fills
Device of air 2, setting inflation through hole 3 in end-fixture 1, side ports of inflation through hole 3 are connected with aerating device 2, and the other end is even
It is connected to the fixed part 4 with workpiece end outline to be detected cooperation, end-fixture 1 is provided for enter both side ends fixture 1
The travel mechanism 5 of the linear movement that row is drawn close relatively, is additionally provided between both side ends fixture 1 and lifts platform 6.Lift and set on platform 6
It is equipped with the arc frame 7 agreeing with outer wall profile on the downside of workpiece.Travel mechanism 5 includes movable stand 8, and movable stand 8 is with end-fixture 1 even
Connect, movable stand 8 is provided with sinciput cylinder 9.Aerating device 2 is inflator pump.It is provided with close for increasing on fixed part 4 medial wall
The sealant layer 10 of envelope property, rubber layer 10 adopts silica gel material, and silica gel is susceptible to deformation, adaptability to changes is good, simultaneously silica gel
Sealing also than ordinary rubber more with outstanding.Sealant layer 10 is internally provided with and strengthens sealing effect by inflating extended volume
The air bag 11 of fruit, the sealing property so becoming big sealant layer 10 with air pressure also strengthens therewith, preferably sealant layer 10
The no any lines in surface be smooth planar surface.Inflation through hole 3 include first through hole 3-1 that is connected with air bag 11 and with
The second through hole 3-2 that workpiece is connected.First through hole 3-1 is annular through-hole and the outside being enclosed in the second through hole 3-2, and first leads to
