Abstract
The utility model discloses a portable fixing device of a vibrating sensor, which comprises a base, a vibrating sensor installing block and a connecting rod, wherein the bottom of the base is a magnet, the vibrating sensor installing block is connected with at least one of vibrating sensors, and the connecting rod is connected with the base and the vibrating sensor installing block. The portable fixing device has the following advantages which are not contained by the device which only detects the unidirectional vibration such as: 1. solving the repeatability for installing the vibrating sensor, and being convenient and fast to install when a vibration measuring point is changed; 2. saving the cost since the equipment to be measured does not need to be damaged and a spacer of the sensor does not need to be bought; 3. being compact in structure, light in weight, and convenient to manufacture and carry; 4. guaranteeing the data measuring quality adequately in consideration of the coupling between the fixing device and a structure to be measured; and 5. being capable of simultaneously collecting the vibration of the structure to be measured on three directions of some position, thereby being capable of describing the three-dimensional vibration mode of the structure, and obtaining the inherent frequency and vibration type of the structure by the spectrum analysis.
Description
Technical field
The utility model relates to the portable fixedly device of a kind of vibration transducer, relates in particular to a kind of stationary installation that can make things convenient for the vibration transducer Fast Installation when determining each order frequency vibration shape of structure in the mechanical oscillatory structure test process.
Background technology
At present, vibration-testing is a kind of method commonly used in the engineering test field.Structure and equipment are carried out vibration-testing and analysis, can check the operation conditions of machine to a certain extent, estimate running quality and its mechanics dynamic perfromance of research, and then seek vibration source, improve the vibration resistance of structure etc.In the test process of structure, often need in advance to beat on by geodesic structure the pad of bolt hole or gluing vibration transducer.Test need be at a plurality of position measurements, and this certainly will be at structure a plurality of positions punching or gluing pad.Punching difficulty and might destroy the intensity of structure relatively structurally in machine running process, and the pad on gluing is generally no longer taken off in the actual test process, this certainly will increase cost.The most important thing is to gather simultaneously the vibration on three directions of certain vibration position, also just can't determine the structural vibrations form.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of vibration transducer portable fixedly device, it has solved the inconvenience that vibration transducer is installed in the vibration-testing process, and the stationary installation that can gather the vibration data on three directions in certain position simultaneously.Characteristics such as having does not influence by geodesic structure, easy for installation, and dismounting is easy, and is reusable.
The utility model is realized by following measure:
The portable fixedly device of a kind of vibration transducer of the present utility model is characterized in that, comprising:
Base, bottom are magnet;
The vibration transducer mounting blocks is connected with at least one vibration transducer; With
Connecting link connects base and vibration transducer mounting blocks.
In order to measure the vibrating numerical on three directions in a position simultaneously, the vibration transducer mounting blocks is connected with a vibration transducer on the X in the space, Y, the Z-direction respectively.
Above-mentioned connecting link is a studs, for convenience detach and installation.
For the ease of installation and removal, above-mentioned vibration transducer mounting blocks is a square, is provided with an identical and threaded hole that match with the coupling bolt of connecting link end and vibration transducer on six faces of vibration transducer mounting blocks.
For base top install more firm, above-mentioned base top is the stationary installation base bonding with magnet, described stationary installation base is threaded with connecting link.
The beneficial effects of the utility model are: 1, solved the repeatability that vibration transducer is installed, and easy for installation quick when changing vibration pickup point; 2, do not destroy equipment under test, need not to buy the pad of sensor, save cost; 3, compact conformation, in light weight, be convenient to make and carry; 4, take into full account stationary installation and, guarantee the test data quality by the coupling of geodesic structure.5, can gather simultaneously by the vibration on three directions in certain position of geodesic structure, can describe out the three dimensions vibration mode of structure whereby, and then obtain the natural frequency and the vibration shape of structure, and this is that only to survey single direction vibration not available by spectrum analysis.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a side structure synoptic diagram of the present utility model.
Among the figure: 1 magnet, 2 stationary installation bases, 3 studs, 4 vibration transducer mounting blocks, 5 vibration transducers.
Embodiment
As shown in Figure 1, 2, the portable fixedly device of vibration transducer of the present utility model comprises: base, connecting link and vibration transducer mounting blocks 4.Base bottom is a magnet 1, and top is the stationary installation base 2 bonding with magnet 1, and magnet 1 is the identical circle of diameter with stationary installation base 2.Connecting link is a studs 3.Vibration transducer mounting blocks 4 is a square, be provided with a measure-alike threaded hole on six faces of vibration transducer mounting blocks 4, threaded hole all can match with coupling bolt and the studs 3 on the vibration transducer 5, can arbitrarily connect stud bolt 3 and vibration transducer 5.The other end of studs 3 can be screwed into the center of stationary installation base 2 by screw thread.Vibration transducer mounting blocks 4 is connected with a vibration transducer 5 on the X in the space, Y, the Z-direction respectively, can gather the vibration on three directions in same position simultaneously.
Its principle of work is: when concrete the use, only need the vibrating sensing stationary installation is moved to the smooth position that needs the moving data of vibration measuring (level and vertical direction all can), firmly be adsorbed on the equipment under test with magnet 1,1,2 or 3 vibration transducer 5 on the direction be installed then tested and get final product.Solved the inconvenience that vibration transducer 5 is installed in the vibration-testing process, can lay vibration measurement device in any smooth position of equipment, and can gather the vibration data on three directions in certain position simultaneously, having does not influence by geodesic structure, easy for installation, dismounting is easy, reusable advantage.Studs adopts the standard model, is convenient to buying.
The foregoing description is described to be in order to specify this patent; though describe by specific term in the literary composition; but can not limit the protection domain of this patent with this; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
