Since the device is provided with multiple product installation surfaces, various product installations and tests can be performed by replacing different connectors. By setting up multiple fixture mounting surfaces, it is possible to conduct tests in all directions of the product, and also conduct vibration and shock tests on multiple products at the same time. The test time and cost are greatly saved, and the efficiency is improved. It only takes about 10 minutes to change the direction once; the vibration force transmission of the vibration fixture is reasonable, which improves the quality of the vibration test; when changing the direction, it is not necessary to disassemble the test product, so the probability of the product being artificially damaged is greatly reduced.
Description
Technical field
The utility model is related to vibratory impulse testing experiment equipment technical field, more particularly to a kind of vibration impact experiment folder
Tool.
Background technology
Equipment, fastener on aerospace craft etc. can be received during rocket launching is gone up to the air with whole arrow
To the random vibration that air drag and flame accelerate to cause, accordingly, it would be desirable to the large number quipments on aerospace craft, fastening
Part etc. carries out vibratory impulse test, with the structural fatigue intensity of apparatus for checking, i.e., whether can be because by the actual use ring of simulation
Border and cause fatigue failure or damage.
In order to realize requirement of the product to vibratory impulse in laboratory, usual technical staff can design corresponding fixture and come
Into experiment, test products are fixed on testing stand by fixture, and practice operation realizes the environment of vibratory impulse.Existing
Have in technology, vibration tong demand is big, it is necessary to according to different shape of products, size, intensity etc. come design fixture, cause to shake
Dynamic test cost increases.When a direction for completing test product vibrates, it is necessary to change next measurement direction, change every time
The demolition, installation of product and the wiring of product are required for taking a significant amount of time during measurement direction, take around 1-2 hour, and every
During secondary replacing direction, the artificial damage for causing the abrasion of product appearance or attachment screw screw thread is all particularly easy to.
Furthermore, it is understood that if because vibration test causes the damage of product, related personnel can be carried out to product
Follow-up improvement, this also exactly first purpose of vibration impact experiment.But if after being dismounted for multiple times, occur in that artificial damage
Bad, related personnel may judge by accident to the damage of product, it is believed that be damage that vibration impact experiment is caused, then go to be changed
Enter, undoubtedly waste substantial amounts of time, money and resource；And the experiment to carrying out before is required for zero, again again
Tested, greatly increased experimentation cost.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of vibration impact experiment fixture, solution
Certainly existing vibration impact experiment high cost, the time-consuming, problem of easy artificial damage.
The utility model to achieve the above object, using following technical scheme：
A kind of vibration impact experiment fixture, it is characterised in that:Including jig main body, the jig main body includes at least two
Fixture mounting surface and two product mounting surfaces, described two product mounting surface upper bands have the connector for fixing product, institute
Two fixture mounting surfaces are stated to be fixed with vibration mechine by fastener.
Preferably, the jig main body is hollow square body.
Preferably, the jig main body has three fixture mounting surfaces, and three fixture mounting surfaces are mutually perpendicular to two-by-two,
Each fixture mounting surface is detachably mounted on vibration test table top.
Preferably, the product mounting surface is two, is mutually orthogonal to one another.
Preferably, fixing hole is carried on three fixture mounting surfaces.
Preferably, the quantity of the fixing hole on each fixture mounting surface is four, and square arrangement is set.
The beneficial effects of the utility model are:Relative to prior art, because the present apparatus sets multiple product mounting surfaces, lead to
Cross and change different connectors and can carry out the installation of multiple product with experiment.By setting multiple fixture mounting surfaces, can be right
The all directions of product are tested, and also can simultaneously carry out the vibration impact experiment of more than one piece product.When greatly saving experiment
Between and expense, improve efficiency.Changing the time in direction only needs 10 minutes or so；The vibration force transmission of vibration tong is closed
Reason, improves the quality of vibration test；Test products, therefore product need not be dismantled by the probability of artificial damage when changing direction
Greatly reduce.
Brief description of the drawings
Accompanying drawing 1 is stereogram of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.As shown in Figure 1,
A kind of vibration impact experiment fixture, including jig main body 1, the jig main body include at least two fixture mounting surfaces 2 and two
Individual product mounting surface 3, described two product mounting surface upper bands have the connector 4 for fixing product, and described two fixtures are installed
Face is fixed by fastener with vibration mechine.The fastener can select bolt and nut and fix, it is also possible to select other quick
Fixed structure.The jig main body is hollow square body, and in the utility model, the jig main body has three fixture peaces
Dress face, three fixture mounting surfaces are mutually perpendicular to two-by-two, and each fixture mounting surface is detachably mounted to vibration mechine
On face.The product mounting surface is two, is mutually orthogonal to one another.
For the ease of jig main body is arranged on vibration mechine, described in the utility model on three fixture mounting surfaces
