Embodiment Construction

[0015] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. as attached figure 1 As shown, a vibration shock test fixture includes a fixture main body 1, and the fixture main body includes at least two fixture installation surfaces 2 and two product installation surfaces 3, and the two product installation surfaces are provided with connections for fixing products Part 4, the two fixture installation surfaces are fixed to the vibration test bench by fasteners. The fasteners can be fixed by bolts and nuts, or other fast fixing structures can also be selected. The main body of the fixture is a hollow cube. In the present invention, the main body of the fixture has three fixture installation surfaces, two of which are perpendicular to each other, and each fixture installation surface can be detachably fixed on the vibration test table superior. There are two produc...

Abstract

The present invention relates to the technical field of vibration impact test equipment and provides a vibration impact test fixture which comprises a fixture body which comprises at least two fixture mounting surfaces and two production installation surfaces. The production installation surfaces are provided with connection pieces for fixing a product, and the two production installation surfaces are fixed to a vibration test platform through fasteners. Since the device is provided with multiple installation surfaces, the installation and test of multiple products can be carried out through replacing different connection pieces. Through arranging the multiple fixture installation surfaces, each direction of the product can be tested, and the vibration impact tests of multiple products can be carried out at the same time. The test time and cost are greatly saved, and the efficiency is improved. About 10 minutes are needed in one time of changing a direction. The vibration force transfer of the vibration fixture is reasonable, and the quality of the vibration test is improved. The removal of the test product is not needed in changing a direction, and thus the probability of the man-made damage of the product is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of vibration and shock test equipment, in particular to a vibration and shock test fixture. Background technique [0002] During the launching process of the rocket, the equipment and fasteners installed on the spacecraft will be excited by the random vibration caused by the air resistance and flame acceleration along with the whole rocket. Fasteners, etc. are subjected to vibration and shock tests to assess the structural fatigue strength of the equipment, that is, whether it will cause fatigue failure or damage due to the simulated actual use environment. [0003] In order to meet the vibration and shock requirements of the product in the laboratory, technicians usually design corresponding fixtures to complete the test, fix the test product on the test bench through the fixture, and run the test bench to realize the vibration and shock environment. In the prior art, there is a large demand for vibration ...
