Description
Technical field
The present invention relates to a kind of flowmeter and lead to vibration test vibration tong.In particular, the present invention is mounted on shaking table, and for all kinds of flowmeter is reliably connected with vibration table, and guaranteed flow meter can at a kind of device of communication in moving oil work that shakes.
Background technology
The object of vibration test is to do a succession of controllable vibration simulation in test, and whether test products, in life cycle, can bear the test of transport or vibration environment factor, also can determine the requirement standard of product design and function.According to statistics data display lifting 3% design level, by the recovery of increase by 20% and reduce 18% every unnecessary expenditure.Vibration simulation also has diverse ways according to different objects, as resonance search, resident, the scan round of resonating, random vibration and stress screening etc.Vibration test is the important component part of environmental test, and fixture plays very important effect in vibration test.Due to the restriction by factors such as product size, vibration table installation hole shape sizes, product needs fixture to be fixed connection when carrying out vibration test.The dynamic perfromance of fixture is the key factor affecting product testing true reappearance.Irrational jig Design, manufacture and install and use easy generation " cross vibration " and " owing to vibrate ", even if reach the requirement controlling spectrum reluctantly, also will increase the weight of the load of vibrational system, especially when the responding range of shaking table is less, contradiction can be more outstanding.The dynamic characteristic parameters such as the location of its rigidity, quality, center of gravity are the key factors affecting product testing true reappearance.At present, the fixture used in vibration test, often there is larger distortion in its stress transmitted.The major function of vibration test fixture is by the energy transferring of shaking table generation to testpieces, and the basic demand of design fixture has: 1) can easily be fixed on vibration table by testpieces; 2) quality of fixture wants light, and rigidity wants large, and himself natural frequency will try one's best height, and the lowest resonant frequency of separating test part is more far better; 3) easy to process, good manufacturability; 4) cycle of design processing is short.The weight of fixture is an important parameter in jig Design, often making jig Design overweight to improve the rigidity of fixture, too much " having eaten up " thrust of shaking table, having affected the maximum capacity to testpieces in design.Especially for the vibration test of large-scale experiment part, whether the weight of its fixture directly has influence on test and can be undertaken by the test condition of design.Therefore, in vibration test, test fixture design is an important step in vibration test, and the quality of jig Design is directly connected to the credibility of vibration test result, even has influence on the success or not of vibration test.The vibration test fixture of all kinds of flowmeter in prior art is all adopt to fill fuel oil in flowmeter inside, and with plug shutoff turnover oilhole, recycling clip clamping flowmeter, is connected to switching device and shaking table carries out vibration test.The defect of this vibration tong is mainly:
A) flowmeter is in off working state, can not simulate its real service condition in testing laboratory.
B) clip clamped position is uncertain, does not meet true installment state, and easily scratches flowmeter outward appearance.
C) weight of plug makes flowmeter stressed aggravation in vibration test, can not examine the anti-vibration intensity of flowmeter really.
D) oil work can not be led in flowmeter vibration test, the performance of flowmeter can not be monitored at any time, test can not be stopped in the very first time of pinpointing the problems, be analyzed, make test existing defects.
Therefore, need a kind of flowmeter vibration tong not having the brand new ideas of above-mentioned defect of design and use, complete the vibration test of flowmeter more accurately.
Summary of the invention
The weak point that object of the present invention exists for prior art, provides one can avoid scratching flowmeter surface, can lead to oil, and it is little to resonate, can meets different model flowmeter vibration test fixture accurately and reliably in flowmeter vibration test.
The object of the invention is by following technical scheme realize: a kind of versatility flowmeter vibration test fixture, comprise the shaking table card extender 1 be directly connected with vibration table by standard screws and the conversion support 2 be connected with shaking table card extender 1, it is characterized in that: conversion support 2 both sides are fixedly connected with the riser of band reinforcement respectively, riser is equipped with and is each passed through two risers, the front clamp device that coaxial symmetry in opposite directions connects firmly and rear clamp device, flowmeter is fixed between general clamping device 5 that front clamp device and rear clamp device communicate with oil pipe line, and connect oil pipe road by the outer side bayonet slot of riser.
The present invention has following beneficial effect compared to prior art:
The present invention utilizes front clamp device and rear clamp device fixed flow gauge, forward and backward clamp device installs fixed flow gauge by general clamping dress two ends into and out of hydraulic fluid port, vibration test simulation is arranged on the actual conditions of flowmeter in pipeline, the logical oil of flowmeter can be realized in vibration, the instrument and meters such as oscillograph can be utilized to observe the performance change situation of flowmeter in vibration test at any time, and the vibration test of different model flowmeter can be met.Flowmeter is fixed between general clamping device 5 that front clamp device and rear clamp device communicate with oil circuit, realize flowmeter at the communication in moving oil that shakes, the stress distortion of transmitting is little, avoid the situation of flowmeter possibility scratch surface in vibration test, front clamp device 3, rear clamp device 4 and general clamping device 5, its inside and outside surface flatness is good and consistent, ensure the stable of logical oil and coordinate the reliable of installation each other, overcome prior art plug weight and make flowmeter stressed aggravation in vibration test, truly can not examine the defect of flowmeter anti-vibration intensity.Shaking table card extender, front clamp device, rear clamp device and general clamping device are by duralumin (LY) materials processing; The set nut of conversion support and front clamp device, rear clamp device is processed by Steel material, welding, the cooperation between soft, hard material, ensure that the quality of assembly and assembly and the reliability coordinated between assembly with flowmeter and vibration test.
Clamp structure of the present invention is simple, flowmeter is fixed on vibration table and installs convenient fixing, quality is light, rigidity wants large, meets " lightweight ", " rigidity is large ", " intensity is enough " of vibration tong, " center of gravity is low ", " symmetry is good ", " structure is simple ", " easy for installation " several basic demand.And owing to installing the cooperation between reliable and soft, hard material, the resonance that fixture causes is less.In addition, the present invention can also as flowmeter lead to life of oil test installation change fixture to use, substantially increase its practicality.
