Problems solved by technology

[0005] In the vibration test, the product needs to be clamped by the fixture. During the test, the existing fixture will gradually loosen the clamping of the product, and the clamping effect is not good. The product is prone to parallel displacement during the vibration process, which affects the detection. Effect

Abstract

The invention discloses a vibration test clamp structure. The clamp structure comprises a clamp base, the clamp base is hollow. A middle partition plate which is transversely arranged is arranged in the clamp base, inserting holes which are evenly distributed are formed in the middle partition plate, a boss is fixedly connected to the upper end face of the clamp base, a plurality of sets of pressing clamping blocks which are arranged in a rectangular array shape are movably installed at the upper end of the boss, and the side faces of the pressing clamping blocks are attached to one another. The invention relates to a clamp, in particular to a vibration test clamp structure, and belongs to the technical field of vibration test. The pressing clamping blocks distributed in an array mode arearranged at the lower end of the product, when the product is placed on the pressing clamping blocks, the pressing clamping blocks are stressed to move downwards, grooves matched with the product areformed, parallel limiting is formed on the product, then the product is clamped through the clamp, the clamping stability of the clamp is improved, and the detection effect is improved.

Description

technical field [0001] The invention relates to a fixture, in particular to a vibration test fixture structure, and belongs to the technical field of vibration testing. Background technique [0002] The vibration measurement in the environmental vibration test (VIB07) includes two types: one is the vibration measurement of objects that cause noise radiation; the other is the environmental vibration measurement. The most commonly used vibration methods can be divided into two types: Sine vibration and Random vibration. [0003] Vibration test is to simulate the impact of various vibration environments encountered by the product in the transportation, installation and use environment, and to determine whether the product can withstand various environmental vibrations. [0004] The most commonly used vibration methods can be divided into two types: sinusoidal vibration and random vibration. Sinusoidal vibration is a test method often used in laboratories to simulate vibrations...
