Description
Technical field
The utility model relates to a kind of field of mechanical technique, relates in particular to a kind of anchor clamps.
Background technology
Space product in order to check the working condition of product under true environment, according to the GJB regulation, must carry out random vibration test, with checking reliability of products and environmental suitability in development and production run.And in test, in order to make product be installed on the vibration table with holding water and to realize the requirement of multidirectional test, usually adopt anchor clamps to connect product and shaking table, and be delivered on the product the vibration signal on the vibration table is distortionless by anchor clamps, realization is to the test examination of product, with checking reliability of products and environmental suitability, effectively exposing product initial failure and hidden danger of quality improve the dependability of product greatly.If jig Design is not good, anchor clamps and be subjected to synthetic deviation of gravity center shaking table axis of trial product or anchor clamps rigidity deficiency then easily produce resonance, the anchor clamps vibration level will be increased greatly and put on the product, cause the product stress excessive and damage; Another may be because jig Design is improper, adopts sealing or semienclosed box structure, in test can interference temperature, moisture field, and be subjected to trial product the undertesting phenomenon can occur, cause and transmit magnitude and be attenuated, and reach test examination requirement.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of Frequency transfer of providing is good, change easy, the easy to operate random vibration test anchor clamps of direction.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions:
Random vibration test anchor clamps of the present utility model are made up of clamp body 1, installing plate 2 and reinforcement 3.Wherein: installing plate 2 is fixed in clamp body 1 diametrical position and vertical with it, is T type structure; Be provided with four reinforcements 3 between installing plate 2 and the clamp body 1, be symmetricly set in two of installing plate ends respectively.
Above-mentioned random vibration test anchor clamps, wherein: clamp body 1 is a circular slab, which is provided with shaking table corresponding hole when docking is installed.
Above-mentioned random vibration test anchor clamps, wherein: installing plate 2 is the special-shaped slab construction of hollow, which is provided with two groups of position, corresponding hole and irregular cavities 4 when installed by trial product to dock; Installing plate 2 upper surfaces are circular arc, and installing plate 2 lower surfaces and clamp body 1 are by being welded to connect, and installing plate 2 adopts transition fit with clamp body 1.
The utility model compared with prior art, by above technical scheme as can be known, each part of anchor clamps is by being welded to connect, good rigidly reaches the purpose that suppresses resonance thereby make anchor clamps become the excited frequency that a complete firm body reduces vibration.Do not have soft materials such as liner when installed by trial product on anchor clamps, thereby improved the natural frequency of anchor clamps, make the rank natural frequency (fundamental frequency) of winning be higher than the highest test frequency of product, Frequency transfer is good.Anchor clamps adopt T type structure, structural symmetry, and the effect of eccentricity is avoided in center of gravity and shaking table dead in line, and product can be fixed on the both sides of installing plate simultaneously.Anchor clamps adopt reinforcement jockey body and installing plate, have improved the rigidity of anchor clamps.Anchor clamps can satisfy the vibration test of product Y, Z both direction, and it is easy, easy to operate to change direction, and can be used for the impulse test of product.Thereby be a kind of efficient, practicality and frequency characteristic random vibration test anchor clamps preferably.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
