Abstract
The utility model provides a high frequency and high acceleration triaxial vibration testing clamp for a small sample, comprising a body. The body possesses a cubic structure, at least one surface of the body is provided with a model A and a model B simultaneously, the body is provided with a plurality of screwed holes, the clamp also includes a block cover, and the block cover is provided with a plurality of through holes. According to the high frequency and high acceleration triaxial vibration testing clamp for a small sample, the structure is simple, usage is convenient, the small sample to be measured is rapidly assembled, the directions of the model A and the model B on each surface are different from the directions of the corresponding adjacent model A and the model B, thereby the small sample is just required to be arranged for test at another surface, the axial transition of vibration is realized, the small sample is tightly compacted on the model A or on the model B by the block cover to be effectively fixed, thereby the small sample is prevented from flying out of a vibration platform in the vibration test process, and the test security and reliability are raised.
Description
Technical field
The utility model relates to a kind of fail-test fixture, particularly a kind of fixture of testing use for three shaft vibrations of small sample high frequency and high acceleration.
Background technology
Vibration test is in the transportation of expection and the resistivity of environment for use for evaluation components and parts, parts and complete machine.The major parameter of vibration test has the parameters such as acceleration, cross-over frequency, sweep rate, time of vibration, direction of vibration.Common vibration test is all to adopt the materials such as steel plate and screw rod to be fixed, and typically uses steel plate and clamps the product that need to test, then tie down steel plate with screw rod steel plate is fixed, thereby product to be measured is carried out vibration-testing.High frequency and high acceleration vibration-testing for small sample, often occur because sample is fixing insecure, cause the phenomenon that flies out in the sample test process or damage sample, therefore, if small sample is effectively fixed, become reliability testing field problem demanding prompt solution thereby carry out smoothly high frequency and high acceleration vibration-testing.
The utility model content
Existing small sample carries out high frequency and the high acceleration vibration-testing can not carry out effectively fixing problem in order to solve, and the utility model provides following technical scheme:
Three shaft vibration fixture for testings of a kind of small sample high frequency and high acceleration, this fixture comprises body, described body is cube structure, at least one face of described body offers model A and Model B simultaneously, described body is provided with a plurality of threaded holes, this fixture also comprises Ka Gai, and described card covers and offers a plurality of through holes.
As a kind of preferred version of the present utility model, described body is hollow-core construction.
As another kind of preferred version of the present utility model, the described model A of every one side is different with described Model B direction from the described model A of adjacent surface with described Model B.
As another preferred version of the present utility model, the material of described body and described Ka Gai is aluminium.
The utility model advantage is:
1, the utility model is simple in structure, and is easy to use, can fast small sample to be measured be installed;
2, because the model A of each face of the utility model and Model B are different with the Model B direction from model A on adjacent direction face, therefore, as long as carry out installation testing by small sample to be measured being changed a face, can realize vibrating shaft to conversion;
3, the utility model is pressed in model A or Model B by Ka Gai with small sample, effectively small sample is fixed, thereby guarantees that small sample can not fly out from shaking table in the vibration-testing process, has improved security and the reliability of test.

Fig. 2 is the clamped cover structure schematic diagram.
Number in the figure is:
1-body, 11-threaded hole, 2-model A
3-Model B 4-card covers 41-through hole
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.
As shown in accompanying drawing 1 the utility model structural representation and accompanying drawing 2 clamped cover structure schematic diagram, three shaft vibration fixture for testings of a kind of small sample high frequency and high acceleration, this fixture comprises body 1, body 1 is cube structure, at least one face of body 1 offers model A2 and Model B 3 simultaneously, body 1 is provided with a plurality of threaded holes 11, and this fixture also comprises card lid 4, and card covers and offers a plurality of through holes 41 on 4.
Each surface model A2 is different with Model B 3 directions from the model A2 of adjacent surface with Model B 3.By small sample is installed on different faces, realize the small sample disalignment to vibration-testing.The material of body 1 and Ka Gai 4 is aluminium, thereby has alleviated the weight of body 1, has improved the security of test.
A plurality of through holes 41 that card covers on 4 can be realized the pressing of various ways with model A2 or Model B 3, thereby realize the popularity of the utility model scope of application.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
