Universal Flowmeter Vibration Test Fixture

Abstract

A universal flowmeter vibration test fixture proposed by the present invention includes a vibration table adapter plate (1) directly connected to the vibration table surface and a conversion bracket (2) connected to the vibration table adapter plate, and the two sides of the conversion bracket are fixed respectively. It is connected with a vertical plate with reinforcing ribs, and the vertical plate is equipped with a front clamping device (3) and a rear clamping device (4) that pass through the two vertical plates and are fixedly connected coaxially and symmetrically. The flowmeter is fixed on the front clamping device Between the universal clamping device (5) communicated with the oil pipeline on the rear clamping device, and connect the oil pipeline through the card slot on the outside of the vertical plate. The invention installs the fixed flowmeter through the oil inlet and outlet ports at both ends of the universal clamping device, and can realize the oil flow of the flowmeter in the vibration, and overcomes the stress of the flowmeter in the vibration test intensified by the weight of the plug in the prior art, which cannot To truly assess the defects of the flowmeter's anti-vibration strength. The invention has the advantages of simple structure, convenient installation and fixing of the flowmeter, light weight and high rigidity, and meets the four basic requirements of the vibrating fixture.

Description

technical field [0001] The invention relates to a vibrating fixture for a flowmeter through-vibration test. More specifically, the present invention is installed on a vibrating table, is a device for reliably connecting various flowmeters with the vibrating table surface, and ensuring that the flowmeter can work through oil in vibration. Background technique [0002] The purpose of the vibration test is to do a series of controllable vibration simulations in the test, to test whether the product can withstand the test of transportation or vibration environmental factors during the life cycle, and to determine the required standards for product design and function. According to statistical data, improving the design level by 3% will increase recycling by 20% and reduce unnecessary expenditures by 18%. There are different methods for vibration simulation according to different purposes, such as resonance search, resonance dwell, cyclic scanning, random vibration and stress sc...

AI Technical Summary

Problems solved by technology

[0003] a) The flowmeter is in a non-working state, and its real use cannot be simulated in the laboratory

[0004] b) The clamping position of the clamp is uncertain, which does not conform to the actual installation state, and it is easy to scratch the appearance of the flowmeter

[0005] c) The weight of the plug increases the stress on the flowmeter during the vibration test, and the anti-vibration strength of the flowmeter cannot be truly assessed

[0006] d) During the vibration test of the flowmeter, it is not possible to work through the oil, and the performance of the flowmeter cannot be monitored at any time, and the test cannot be stopped and analyzed at the first time when a problem is found, so that the test has defects
