Description
Technical field
Field of mechanical technique is the utility model is related to, specifically a kind of brace type acoustical testing device.
Background technology
The acoustic testing method of main flow has two kinds at present, and one kind is suspension method, and one kind is disposed on foam-rubber cushion.Both
Method application with it is similar I take charge of brake class product when following points problem：It can not be used 1. tested sample is overweight, during suspension
Fine rule, thick line can influence the free vibration state of tested sample.It can be sunk when being placed on foam-rubber cushion, cause product bottom sound
Absorbed, it is less than normal to measure result.2. different series product structure is complicated, it is difficult to which testing sample is consolidated by two methods of main flow
It is scheduled on a certain angle or certain position.3. suspension method installation is complicated, position fixing process is difficult, requires very high to operating personnel.
The content of the invention
The utility model is overcome the deficiencies in the prior art, there is provided a kind of brace type acoustical testing device, the brace type are surveyed
The characteristic point by using the upright supports exemplar with rubber vibration isolation structure is put in trial assembly, avoids sinking or hawser fetters, together
When can with the position of the horizontal plane of column and height carry out 3D regulations, to adapt to a variety of different types of products.
To achieve the above object, a kind of brace type acoustical testing device, including fastener, moving guide rail, its feature are designed
It is：One end of fastener is provided with positioned at moving guide rail, the other end of fastener is using threaded support bar connection switching vibration isolation
One end of pad, the other end for vibration isolator of transferring connect top vibration isolator using another threaded support bar.
One end of described fastener is embedded in the groove of moving guide rail.
Described top vibration isolator and the vibration insulation structure that vibration isolator is elastomeric material of transferring.
Described switching vibration isolator is cylindrical structural, and a diameter of 1 ~ 1.5 centimetre of vibration isolator of transferring.
Described top vibration isolator is disc-shaped structure, and a diameter of 1 ~ 1.5 centimetre of top vibration isolator.
The utility model is compared with the existing technology, there is provided a kind of brace type acoustical testing device, the brace type test device
By using the characteristic point of the upright supports exemplar with rubber vibration isolation structure, avoid sinking or hawser constraint, while can be with
The position of the horizontal plane of column and height carry out 3D regulations, to adapt to a variety of different types of products.
The application of this test device, it is therefore an objective to the test knot for making each test to heavy parts to be stablized
Fruit, make result that there is repeatability and acoustics meaning.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Referring to Fig. 1,1 is top vibration isolator, and 2 be another threaded support bar, and 3 be switching vibration isolator, and 4 be threaded support bar, 5
It is moving guide rail for fastener, 6.
Embodiment
The utility model is described further below according to accompanying drawing.
As shown in figure 1, being provided with one end of fastener 5 positioned at moving guide rail 6, the other end of fastener 5 uses screw thread branch
One end of the connection switching vibration isolator 3 of strut 4, the other end of switching vibration isolator 3 connect top vibration isolation using another threaded support bar 2
Pad 1.
One end of fastener 5 is embedded in the groove of moving guide rail 6.According to the situation of actual test, the fixation of fastener 5
Mode is unrestricted, can be positioned in plane, can also be embedded in the groove of moving guide rail etc..
Top vibration isolator 1 and the vibration insulation structure that switching vibration isolator 3 is elastomeric material.
Switching vibration isolator 3 is cylindrical structural, and a diameter of 1 ~ 1.5 centimetre of vibration isolator 3 of transferring.
Top vibration isolator 1 is disc-shaped structure, and a diameter of 1 ~ 1.5 centimetre of top vibration isolator 1.
According to the situation of actual test, the shape of top vibration isolator 1 and vibration isolator 3 of transferring is unrestricted, can be cylinder
Shape or cuboid structure, its shape can enter line translation according to test environment and test request, to reach optimal
The effect of test.
During operation, the quantity of whole test device is unrestricted, and having reached fixed test product is advisable, and can select at 3 points
Or more can make exemplar maintain use state or test form the strong point, tested characteristic point is as close to vibration
Node, you can complete acoustical testing.
Support column tip designs damping structure；Support column at least possesses two grad vibration isolation structure；Support column position and characteristic point
Overlap；Support column height is adjusted to keep the test mode of sample requirement；Lay acoustical cotton in support column lower end；Arrange signal acquisition
Equipment and start to test.
It is simple in construction, it is easy to operate, and height can be adjusted according to the requirement of test, and can be according to tested test manufacture
The size of product, increase the quantity of brace type acoustical testing device, to reach stable fixed effect.
