Description

The automatic vibration measuring device of bearing

(1) technical field

The utility model relates to a kind of full-automatic vibration measuring machine of deep groove ball bearing that is applied to.

(2) background technology

In the Production of bearing industry, what traditional vibration measuring operation adopted is by manually-operated vibration measuring machine.This kind vibration measuring machine operation get up to need artificial the bearing test station of packing into to be carried out certain pretightning force to the test bearing end face then, debates vibration gauge the bearing outer ring vibration signal is amplified the quality that sound that the back transforms and numerical value are judged bearing through listening.Its shortcoming that also exists is: production efficiency is low and quality bearing quality is different with custom because of individual's hearing; Bearing quality stable poor, and present full-automatic vialog costs an arm and a leg owing to adopt digital processing; Efficient is low, can't in bearing industry, promote.

(3) summary of the invention

In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of automatic vibration measuring device that cost can be judged the bear vibration quality automatically of taking into account.

The technical scheme that the utility model solves its technical matters is:

The automatic vibration measuring device of bearing; Comprise vialog; Described vialog comprises control circuit, and described control circuit comprises the vibration signal of gathering is carried out the amplifying signal amplification module, and the output terminal one tunnel of described signal amplification module connects and is used for crest comparison module that vibration signal and standard value are compared; The high counting number module that the output terminal connection one of crest comparison module is used for counting, the output terminal of described high counting number module connects controller;

One the tunnel directly connects described high counting number module, the continuous time of described high counting number module count vibration signal, the output terminal of described high counting number module also through one continuous time comparison module connect described controller;

The maximum peak value comparison module that one tunnel connection one compares the maximum peak value and the standard extreme value of vibration signal, the output terminal of described maximum peak value comparison module connects controller.

Vibration signal is sampled; Output is amplified through the signal amplification module in the back; Through high counting number module this signal is carried out high counting number and handle, the continuous time that draws this vibration signal is through comparison module comparison continuous time; Allow noise to be judged as high noisy during continuous time when signal exceeds continuous time, finish this test loop in advance; Signal after the amplification also compares through a crest comparison module and standard value; If vibration signal overgauge value then export high level, if less than standard value then output low level, the output terminal of crest comparison module connects high counting number module; High counting number module is calculated the high level number; Controller reads the crest number and compares with setting value, if greater than setting value, then is judged as high noisy; Vibration signal also compares itself and standard extreme value through the maximum peak value comparison module simultaneously; Judge whether the standard extreme value of setting before the bear vibration maximal value is greater than test; If overgauge extreme value; Also will be judged as high noisy, and just start corresponding action after controller is judged and accomplish product selecting, and get into next product test circulation.The bear vibration quality of requirements is provided with: 1. vibration signal overgauge continuous time value; 2. at the appointed time the crest sum of vibration signal overgauge value greater than setting value; 3. at the appointed time the vibration signal maximal value greater than the maximum peak value setting value.More than three kinds of situation be judged as high noisy when one or more occurring.

The beneficial effect of the utility model is: the utility model utilizes existing equipment to carry out automatic improving, and minimizing equipment drops into; Reduce operative employee's number and alleviate operative employee's labour intensity, reduce personal error, guaranteed the quality of product.

(4) description of drawings

Fig. 1 is the electrical block diagram of the utility model.

(5) embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

As shown in Figure 1, the automatic vibration measuring device of bearing comprises vialog; Described vialog comprises control circuit, and described control circuit comprises the vibration signal of gathering is carried out amplifying signal amplification module 1, and the output terminal one tunnel of signal amplification module 1 connects and is used for crest comparison module 2 that vibration signal and standard value are compared; The high counting number module 3 that the output terminal connection one of crest comparison module is used for counting; The output terminal of high counting number module connects controller 5, and the vibration signal after the amplification compares through crest comparison module 2 and standard value, if vibration signal overgauge value then export high level; If less than standard value then output low level; The output terminal of crest comparison module connects high counting number module 3, and high counting number module is calculated the high level number, and controller reads the crest number and compares with setting value; If greater than setting value, then be judged as high noisy; The output terminal of signal amplification module 1 also have one the tunnel directly to connect described high counting number module 3, the continuous time of high counting number module count vibration signal, the output terminal of high counting number module is also through the described controller of continuous time comparison module 4 connections; Vibration signal is sampled; Output is amplified through the signal amplification module in the back; Through high counting number module this signal is carried out high counting number and handle, the continuous time that draws this vibration signal is through comparison module 4 comparisons continuous time; Allow noise to be judged as high noisy during continuous time when signal exceeds continuous time, finish this test loop in advance; The maximum peak value comparison module 6 that also has one tunnel connection one that the maximum peak value and the standard extreme value of vibration signal are compared of signal amplification module output terminal, the output terminal of maximum peak value comparison module 6 connects controller.Vibration signal also compares itself and standard extreme value through the maximum peak value comparison module; Judge whether the standard extreme value of setting before the bear vibration maximal value is greater than test; If overgauge extreme value; Also will be judged as high noisy, and just start corresponding action after controller is judged and accomplish product selecting, and get into next product test circulation.

Simultaneously the bear vibration quality of requirements is provided with: 1. vibration signal overgauge continuous time value; 2. at the appointed time the crest sum of vibration signal overgauge value greater than setting value; 3. at the appointed time the vibration signal maximal value greater than the maximum peak value setting value.More than three kinds of situation be judged as high noisy when one or more occurring.The utility model utilizes existing equipment to carry out automatic improving, and minimizing equipment drops into; Reduce operative employee's number and alleviate operative employee's labour intensity, reduce personal error, guaranteed the quality of product.
