Specific embodiment
The preferred embodiment that the utility model is described below in conjunction with attached drawing, to one preferred embodiment of the utility model
In technical solution be clearly and completely described.
- Fig. 2 referring to Figure 1, the utility model include pedestal, and the top of pedestal is fixedly installed bottom plate 3, further includes
Upper mounted plate 1, at least one middle fixing plate 2, the matching used screw rod 7 of multiple groups and nut 6；Fixed plate 1, centre are solid
Fixed board 2 and 3 middle part of bottom plate offer the round hole penetrated for cylindrical air exhaust catalytic converter, and the edge of round hole is set
There is locating groove corresponding with cylindrical air exhaust catalytic converter edge；Along the circle on fixed plate 1 and bottom plate 3
Shape hole circumferentially equidistantly offers multiple screw holes, and the screw rod 7 may pass through screw hole and be fixed by nut 6；On the pedestal also
It is provided with the inlet chamber 8 of upper end opening, is provided with and communicated with air inlet pipe 4 with inlet chamber 8.
In the present embodiment, the open end of the inlet chamber 8 is equipped with spoiler 11, is uniformly provided on the spoiler 6
Multiple flow-disturbing holes.Add spoiler 11 make to be passed through air-flow it is more uniform.
In the present embodiment, the pedestal further includes bottom plate 10, and multiple mounting holes 5 are offered on bottom plate 10.Pass through mounting hole 5
Pedestal can be connect with shake table and carry out thermal vibration test.
In the present embodiment, it is fixedly installed multiple stiffening plates 9 between the bottom plate 10 and bottom plate 3, makes whole device
It is more firm.
Refer to Fig. 3, the working principle of the utility model are as follows:
When testpieces number is 1, catalytic converter testpieces 12 is placed on pedestal vertically, catalytic converter examination
The upper end-face edge for testing part 12 is caught in the locating groove of upper mounted plate 1, and the locating groove that lower edge is caught in bottom plate 3 carries out pre-
It is fixed；Then multiple screw rods 7 are extended through in upper mounted plate 1 and the corresponding screw hole of bottom plate 3, adjusts and determines catalyzed conversion
It is by tightening nut 6 that catalytic converter testpieces 12 is fixed behind the position of device testpieces 12；It is connect by pedestal with shake table,
Thermal exhaust is passed through in inlet chamber 8 by air inlet pipe 4 and carries out thermal vibration test.
When testpieces number is 2, since middle fixing plate 2 is equipped with positioning fluting, pass through between 2 testpieces
Between the connection pre-determined bit of fixed plate 2, be pre-positioned again by locating groove on upper positioning plate 1 and lower positioning plate 3 up and down, it is subsequent fixed
Mode is same as above.
Fixation for 2 or more testpieces, the number that need to only increase middle fixing plate 2 can be realized.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
