Abstract
This utility model discloses a fixing clamp for a hand-held vibration measurer, comprising a cylinder fixed station the top of which is provided with an installation hole for the vibration measurer probe, a standard sensor butt-joint bolt is positioned on the bottom of the fixed station; the side of the fixed station are provided with bolt holes communicating with the installation hole for the vibration measurer probe; and fixing bolts are installed within the bolt holes. The fixing clamp for the hand-held vibration measurer avoids the problems that the probe of the vibration measurer enables the stress on the standard vibration platform to be uneven because of human factors, that the data is unstable when the vibration signal is converting to the electric signal, and the damage on the standard vibration platform which is caused by the vibration detection probe detecting the standard vibration signal on the platform of the vibration measurer can be prevented. Furthermore, the fixing clamp for the hand-held vibration measurer can realizes one-person operation, reduce detection labor intensity and reduce the manpower resources.
Description
Technical field
The utility model belongs to vialog Calibration Technology field, relates to a kind of handy vibrometer stationary fixture.
Background technology
Vibration-testing is the important means that realizes equipment state and fault diagnosis, and the signals such as the amplitude of the vibration of rotary machine and rolling bearing, speed, acceleration and frequency are measured, and is the important instrument of judgement, analytical equipment ruuning situation.Work is at present to examine and determine according to the technical requirement of JJG676-2000 < < work vialog > > vertification regulation by the calibration method of vialog.Calibration equipment is handy vibrometer and standard vibration cover group (comprising standard transducer, power amplifier, conditioning amplifier, standard vibration machine and computer control system).During calibrating, grasp handy vibrometer, make the sensing probe of vialog and the standard vibration machine vibration table contact induction vibration frequency of standard vibration cover group, standard transducer converts vibration signal to electric signal, by power amplifier, computing machine to signal processing analysis, demonstrate the signals such as amplitude, acceleration, speed, frequency of vibration, complete the calibrating of vialog and judge that whether detected Vibration Meter is qualified effectively.There is following problem in the mode that vialog calibrating is held in above-mentioned employing:
(1) different verification workers is in when work, and because tightness and the support dynamics of everyone hand-held detected Vibration Meter are different, the measurement data of vialog can be affected, and causes examining and determine data unstable;
(2) standard vibration machine protective surface is that nonmetallic materials are made, and smooth surface is flexible, cracky and expensive.Therefore, often the metal sensing probe of detected Vibration Meter is placed on standard vibration machine and receives vibration signal, easily cause the wearing and tearing of standard vibration machine vibration table;
(3) verification process must be carried out by two verification workers simultaneously, and a verification worker is responsible for computer-controlled operation, the hand-held detected Vibration Meter of another verification worker, and for a long time vialog is vertically placed in to vibration table Monitoring Data.
Utility model content
The purpose of this utility model is providing a kind of handy vibrometer stationary fixture, to avoid direct hand held vibration appearance easily to cause the problem that calibrating data are unstable and standard vibration machine vibration table is easy to wear.
For this reason, the utility model adopts following technical scheme:
A kind of handy vibrometer stationary fixture, comprise cylindrical fixed station, the top of described fixed station is provided with vialog probe mounting hole, the bottom of fixed station is provided with standard transducer to connecting bolt, the side of fixed station is provided with the screw hole connecting with described vialog probe mounting hole, in described screw hole, is equipped with gib screw.
Further, described screw hole is three, and along circumference, is evenly distributed on the lateral surface of fixed station.
Further, the material of described fixed station is aluminium alloy or bakelite.Its material is mainly the requirement that will meet light weight.
The beneficial effects of the utility model are: (1) is avoided making standard vibration table top discontinuity, the unsettled problem of data when vibration signal converts electric signal to because human factor causes vialog probe; (2) avoid detecting the damage to standard vibration machine vibration table when vialog table top measurement standard vibration signal of Vibration Meter probe; (3) can realize one man operation, after vialog is fixing on fixture, without the another long-time hand-held vialog of collating staffing, make to be stabilized on standard vibration machine vibration table, alleviate calibrating labour intensity, save human resources.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for utilizing vibration calibrating schematic diagram of the present utility model.
In figure, 1-fixed station, 2-vialog probe mounting hole, 3-standard transducer is to connecting bolt, 4-screw hole, 5-gib screw, 6-handy vibrometer, 7-vibration gauge probe, 8-standard transducer, 9-vibration table, 10-standard vibration machine.
Embodiment
As shown in Figure 1, a kind of handy vibrometer stationary fixture, comprise cylindrical fixed station 1, the top of fixed station 1 is provided with vialog probe mounting hole 2, the bottom of fixed station 1 is provided with standard transducer to connecting bolt 3, the side of fixed station 1 is provided with the screw hole 4 connecting with vialog probe mounting hole 2, is equipped with gib screw (not shown) in screw hole 4; And screw hole 4 is three, and along circumference, be evenly distributed on the lateral surface of fixed station 1; The material of fixed station 1 is aluminium alloy or bakelite.
As shown in Figure 2, during use, by standard transducer, connecting bolt 3 is fixed the utility model stationary fixture and standard transducer 8, in the vialog probe mounting hole 2 of the vertical insertion stationary fixture of the probe of handy vibrometer 67, tighten the gib screw 5 being assemblied in screw hole, handy vibrometer 6 is vertically fixed in vialog probe mounting hole 2.Standard transducer 8 is placed on the vibration table 9 of standard vibration machine 10, the vibration frequency that stationary fixture can be experienced standard transducer 8 conducts on handy vibrometer 6, the series of problems of having avoided direct hand-held measurement to cause.
Claims (3)
