Between be additionally provided with and lift platform.As it is of the present utility model preferably, described lifting be provided with platform agree with workpiece downside outer wall
The arc frame of profile.
Include movable stand as of the present utility model preferred, described travel mechanism, the movable stand is pressed from both sides with the end
Tool connection, is provided with sinciput cylinder on the movable stand.
It is inflator pump as of the present utility model preferred, described aerating device.
As of the present utility model preferred, the fluid sealant for increasing sealing is provided with described fixed part madial wall
Layer.So design is to eliminate the gap between fixed part and catalyst converter, lift-off seal performance.
As it is of the present utility model preferably, described sealant layer is internally provided with close to strengthen by inflating extended volume
Seal the air bag of effect.So design causes that the sealing of fixed part is lifted as air pressure is lifted, and completely solves air pressure lifting
During sealing decline problem.
As it is of the present utility model preferably, described inflation through hole include the first through hole led to the airbags and
The second through hole being connected with workpiece.This ensures that inflate simultaneously.
As of the present utility model preferred, described first through hole is for annular through-hole and is enclosed in the outer of second through hole
Side, the central axes of described first through hole and second through hole.This ensures that air pressure equalisation during inflation.
The utility model has the advantages that：
The utility model possesses good airproof performance, testing efficiency advantage high.

Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, the first embodiment of the present utility model includes being arranged on end-fixture 1 and the inflation of opposite side
Device 2, sets inflation through hole 3 in end-fixture 1, the side ports for inflating through hole 3 are connected with aerating device 2, other end connection
There is the fixed part 4 coordinated with workpiece end outline to be detected, be provided for carrying out both side ends fixture 1 in end-fixture 1
The travel mechanism 5 of the relative linear movement drawn close, is additionally provided between both side ends fixture 1 and lifts platform 6.Lift and set on platform 6
There is the arc frame 7 for agreeing with workpiece downside outer wall profile.Travel mechanism 5 includes movable stand 8, and movable stand 8 is connected with end-fixture 1,
Sinciput cylinder 9 is provided with movable stand 8.Aerating device 2 is inflator pump.The specific setting of fixed part 4 is according to catalyst converter two ends
The difference of shape and change, be highly important designing points so it is exactly to be fitted with outline design to coordinate with outline.
The move mode of travel mechanism 5 must be linear, very stable could be compressed catalyst converter so when air pressure is lifted.
The effect one of travel mechanism 5 is that, in order to clamp catalyst converter, two is that, in order to keep sealing, this point effect is mainly reflected in inflation
During, air pressure lifting causes fixed part 4 to be moved toward both sides in catalyst converter, and so as to cause sealing to reduce, and travel mechanism 5 is just
Must dynamically coordinate this relative movement move and clamp again catalyst converter guarantee sealing.Same is aerating device 2
Charging device, such as water pump can be substituted for.
As shown in Figure 2 to Figure 3, second embodiment of the present utility model include being arranged on the end-fixture 1 of opposite side with
And aerating device 2, inflation through hole 3 is set in end-fixture 1, the side ports for inflating through hole 3 are connected with aerating device 2, another
End is connected with the fixed part 4 coordinated with workpiece end outline to be detected, is provided for both side ends fixture in end-fixture 1
