Abstract
The utility model provides a clamp for a high frequency vibration test, comprising a pedestal and an installing plate vertically arranged on the pedestal. The pedestal is provided with a location hole, and the installing plate is provided with screwed holes. A plurality of screwed hole are provided and anomaly distributed. Two sides of the installing plate are respectively provided with a reinforcement member. The pedestal, the installing plate and the reinforcement member are prepared from aluminum alloy. The utility model provides the advantages as following: the structure is simple, usage is convenient, product fixation is firmer, and the problem of product flying out under a high frequency and large acceleration test condition caused by weak fixation among the product, a screw and a steel plate is overcome.
Description
Technical field
The utility model relates to a kind of fail-test fixture, particularly a kind of fixture that carries out high-frequency, high acceleration vibration for product.
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.For some product, higher for the requirement of frequency and acceleration.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 carry out vibration-testing.The method in process of the test, often can the situation that product flies out from shaking table occur because fixing firm not for frequency and the demanding product of acceleration in vibration processes, cause sample to damage, impact test effect.Therefore, how safety, the vibration test of carrying out efficiently high-frequency and high acceleration become fail-test field problem demanding prompt solution.
The utility model content
For the vibration test that solves existing high-frequency and high acceleration easily produces the problem that product flies out, the utility model provides following technical scheme:
A kind of fixture for the dither test, this fixture comprises base and the installing plate of at right angle setting on described base, offers pilot hole on described base, offers threaded hole on described installing plate.
As a kind of preferred version of the present utility model, described threaded hole has a plurality of, and is irregular distribution.
As another kind of preferred version of the present utility model, the both sides of described installing plate are separately installed with reinforcement.
As another preferred version of the present utility model, the material of described base, described installing plate and described reinforcement is aluminium alloy.
The utility model advantage is: the utility model is simple in structure, and is easy to use, fixing more firm to product, thus avoided because of screw rod and the steel plate fixed product is insecure issues in high-frequency and high acceleration test condition the problem that the production product fly out.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure is:
1-base, 11-pilot hole, 2-installing plate
21-threaded hole, 3-reinforcement
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, a kind of fixture for the dither test, this fixture comprises that diameter is 40cm, thickness is cup dolly 1 and the square installing plate 2 of at right angle setting on base 1 of 4cm, offer a plurality of pilot holes 11 on base 1, be used for this fixture and be fixed in shaking table, offer a plurality of threaded holes 21 on installing plate 2, and a plurality of threaded holes are irregular distribution, to adapt to the needs of multiple different product test.
Be separately installed with two triangle reinforcements 3 in the both sides of installing plate 2, be used for guaranteeing the intensity of this fixture, improved the security of fixture in process of the test.
The all material of this fixture comprises that the material of base 1, installing plate 2 and strong part 3 is all aluminium alloy.
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.
