Abstract
The utility model discloses a kind of universal chucks suitable for the vibration test of ternary catalyzing unit heat, it is characterized in that, including bottom plate, bottom plate is equipped with bracket, the side of bracket is equipped with inclination mounting plate, and the angle tilted between mounting plate and bottom plate is 45 °, tilts the top of mounting plate equipped with the exhaust mounting plate for fixing products export flange, the lower part of mounting plate is vented equipped with the hoop component for fixing product, the input end and inclination mounting plate of product are connected and fixed.The utility model substantially increases the first-order modal of chucking appliance system, reduces to exemplar failure energy, to greatly reduce so that preventing, exemplar caused by resonating because of fixture fails, and ensure that test is gone on smoothly, test result is also more accurately presented.
Description
Technical field
The utility model relates to a kind of universal chucks of automobile three-way catalysts heat vibration test, belong to automobile exhaust equipment skill
Art field.
Background technique
With requiring to be increasingly stringenter to ternary catalyzing unit product durability in the market, in the hot end to exhaust system
During (ternary catalyzing unit) carries out heat vibration test, the magnitude of vibration acceleration, which has, to be increased considerably.Existing heat vibration fixture
As shown in Figure 1 comprising bottom plate 1, bottom plate 1 are equipped with bracket 1 and bracket 2 10, one 9 connection outlet mounting plate 11 of bracket, branch
Frame 2 10 connects import mounting plate 12, forms a complete fixture by these components, but when installing product 7, into
Outlet can only be attached with flange, however the import of existing ternary catalyzing unit is various informative, and versatility is poor.And this
For structure during carrying out wired meta analysis, first-order modal frequency is relatively low, is easy to produce resonance, this kind with ternary catalyzing unit
Structure is in the case where constantly harsh in face of current vibration test condition, during carrying out heat vibration test, the examination of fixed exemplar
The case where testing fixture and exemplar, often failing during the test.
Summary of the invention
Problem to be solved in the utility model is: how to improve the first-order modal of chucking appliance system, and then reduces resonance pair
Chucking appliance system generate destruction, thus reduce test during because fixture design it is improper due to generate product failure the phenomenon that.
To solve the above-mentioned problems, the utility model provides a kind of extension clamp suitable for the vibration test of ternary catalyzing unit heat
Tool, which is characterized in that including bottom plate, bottom plate is equipped with bracket, and the side of bracket is equipped with inclination mounting plate, tilts mounting plate and bottom
Angle between plate is 45 °, tilts the top of mounting plate equipped with the exhaust mounting plate for fixing products export flange, exhaust peace
The lower part of loading board is equipped with the hoop component for fixing product, and input end and the inclination mounting plate of product are connected and fixed.
Preferably, the inclination mounting plate is equipped with the installation notch for adapting to the product of different size, is applicable to
The exemplar of different length, size, versatility are stronger.
Preferably, the hoop component includes the clip one below product and the clip two set on product side.
The utility model passes through the bracket and inclination mounting plate for increasing not only light weight on bottom plate but also having rigidity, constructs a vibration
Dynamic platform expanding table, the installation center of gravity of exemplar is reduced with this；It is shown by model analysis, the first-order modal of chucking appliance system has significantly
It improves.
The utility model structure is simple, suitable for mass production, easy for installation, and operability is stronger, can be applied to ternary and urges
Change in the vibration test of device heat, is effectively reduced because of product failure caused by resonating with fixture.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing heat vibration fixture；
Fig. 2 is the structural schematic diagram of the universal chuck provided by the utility model suitable for the vibration test of ternary catalyzing unit heat.
Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
Embodiment
As shown in Fig. 2, for a kind of universal chuck suitable for the vibration test of ternary catalyzing unit heat provided by the utility model,
Including bottom plate 1, bracket 2 is equipped on bottom plate 1 by welding, the side of bracket 2 is equipped with inclination mounting plate 3, inclination installation
Guarantee that angle is 45 ° between plate 3 and bottom plate 1 by welding.Be vented mounting plate 6 by nut and inclination mounting plate 3 into
The outlet(discharge) flange of row connection, product 7 is attached by nut and exhaust mounting plate 6.The clip 1 of hoop component lower end passes through
It is weldingly fixed on inclination mounting plate 3, the hoop component that clip 25 and clip 1 form is as fixed system, fixed product 7
Entrance.The input end 8 of product 7 is connect by nut with inclination mounting plate 3.
