Description
Technical field
Detection device technical field is the utility model is related to, exactly, it is a kind of hand-transmitted vibration measurement connector.
Background technology
Hand-transmitted vibration is that mechanical oscillation caused by machine or instrument are delivered to people by the hand of operator in production process
The vibration of body or impact phenomenon, vibrate or impacted conference and certain injury is caused to human body, belong to the one of prevention and cure of occupational disease
Kind.The national standard put into effect in 1989《Hand-transmitted vibration specifications of surveys》Put into effect within GB11523-89 and 2001 year《The Chinese people are total to
With state's law on prevention and cure of occupational disease》, measurement and preventing and treating all to hand-transmitted vibration are made that clear stipulaties.
Fig. 1 is the schematic diagram of now widely used hand-transmitted vibration measurement apparatus.In figure：2 be vibrating sensor 221A25,
4 it is hand-transmitted vibration connector, 5 is measured workpiece.When measuring hand-transmitted vibration, connector 4 is adsorbed tested using following magnet 7
On workpiece 5, vibrating sensor 2 is arranged on above connector 4 using screw rod 6, and with the hexagonal nuts 3 below vibrating sensor 2
Standby tight, vibration data caused by measured workpiece 5 is connected to by the data above line connectivity port of vibrating sensor 2 with data wire
On HS5936 vibration measuring sets.
Above-mentioned prior art finds the defects of following and deficiency be present in actual use：1st, due to the absorption of magnet
Power is limited, and loosening and obscission often occurs, has a strong impact on the authenticity of measurement data；2nd, because can only be on connector
One vibrating sensor is installed on one direction, vibrated so can only also measure on measured workpiece caused by a direction；3rd, when
When the surface of measured workpiece is nonferromagnetic material, prior art will be unable to normally be measured；4th, screw rod is that upper and lower diameter is consistent
Standard component, being screwed into depth up and down can not accurately control, so easily being produced between vibrating sensor and connector when vibrating generation
It is raw to loosen.
The content of the invention
The utility model is the technological improvement carried out to connector in the prior art, and its purpose is exactly to carry a kind of installation jail
Gu, the true, accurate of measurement data, the distortion factor it is small, and go for the hand-transmitted vibration of various material surface measured workpieces
Measure connector.
The purpose of this utility model is achieved in that hand-transmitted vibration measurement connector includes：Vibrating sensor and pipe collar,
Vibrating sensor using connecting bolt be connected to hand-transmitted vibration measurement connector on, pipe collar by hand-transmitted vibration measure connector and by
Survey work piece together, it is characterised in that：Hand-transmitted vibration measurement connector except be provided with five following faces preceding screw, on
The left screw of screw, right screw and rear bolt hole, for installing connecting bolt, it is provided with below hand-transmitted vibration measurement connector logical
Hole, pipe collar can extend there through, and the diameter of connecting bolt and hand-transmitted vibration measurement connector connection part point is more than and vibrating sensing
The diameter of device coupling part, to ensure the firm connection of the two.
Compared with prior art the utility model has the advantages that：Firmly install, the vibration data data of acquisition are more true,
Accurately, vibration data signal attenuation is less；Measured workpiece can be measured simultaneously on three-dimensional by installing three sensors simultaneously
Caused mechanical oscillation data, can increase substantially operating efficiency；The vibration number of any material surface vibration workpiece can be measured
According to use range is more extensive；Being connected firmly between vibrating sensor and hand-transmitted vibration measurement connector, is not likely to produce pine
It is dynamic.

Embodiment
Embodiment 1
The utility model hand-transmitted vibration, which measures connector 4 and connecting bolt 14, to use stainless steel to make.Shaken except hand passes
Outside dynamic measurement connector 4 and connecting bolt 14, vibrating sensor 2 is prior art.Pipe collar 9 can be purchased in water-heated article market
, the pipe collar of not size according to the size of measured workpiece, is selected during use.
Five screws on hand-transmitted vibration measurement connector 4, preceding screw 5, upper screw 11, left screw 10, the and of right screw 12
The size of rear bolt hole 13 should be consistent, and vibrating sensor 2 can use one or more according to the difference of measurement direction of vibration.Even
The top screw thread of connecting bolt 14 should be corresponding with the screw thread on vibrating sensor 2, bottom and hand-transmitted vibration measurement connector 4 coupling part
Diameter be greater than top, with control it is respective be screwed into depth, ensure vibrating sensor 2 and hand-transmitted vibration measurement connector 4
Firm connection.
Pipe collar 9 is opened first during use, passes through, is closed tested from the through hole 6 below hand-transmitted vibration measurement connector 4
On workpiece 7, blending bolt 8 is fastened, then connecting bolt 14 is screwed into upper screw 11, vibrating sensor 2 installed above.With it is existing
Technology is identical, and vibration data caused by measured workpiece 7 is connected to by the data above line connectivity port of sensor 2 with data wire
On HS5936 vibration measuring sets.
221A25 can be selected in vibrating sensor 2, and HS5936 can be selected in vibration measuring set, and data wire can match somebody with somebody with vibration measuring set
Set obtains.
