Universal flowmeter vibration test clamp

Abstract

The invention provides a universal flowmeter vibration test clamp which comprises a vibration table adapter plate (1) directly connected with the surface of a vibration table and a switching support (2) connected with the vibration table adapter plate. Vertical plates with reinforcing ribs are fixedly connected to the two sides of the switching support respectively, a front clamping device (3) and a rear clamping device (4) are assembled on the vertical plates, penetrate through the vertical plates respectively and are coaxially, oppositely, symmetrically and fixedly connected, a flowmeter is fixed between universal clamping devices (5) which are arranged on the front clamping device and the rear clamping device and communicated with oil pipelines, and the flowmeter is communicated with the oil pipelines through clamping grooves in the outer sides of the vertical plates. The flowmeter is fixedly mounted through an oil inlet and an oil outlet in the two ends of each universal clamping device, oil can pass through the flowmeter in the vibration process, and the defect that in the prior art, the weight of a plug enables stress on the flowmeter to be increased in a vibration test, and vibration resistance strength of the flowmeter can not be truly tested is overcome. The universal flowmeter vibration test clamp is simple in structure, the flowmeter is convenient to mount and fix, weight is low, rigidity is high, and four basic requirements of a vibration clamp are met.

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...

Problems solved by technology

[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
