Below, embodiments of the present invention are described.
Fig. 1 is the summary pie graph that completes testing fixture of automatic transmission.
The device that completes inspection (performance test etc.) that completes testing fixture 1 and be the automatic transmission 2 after having assembled in the final operation of the manufacturing process of automatic transmission, abnormity determining device 10 is monitor the vibration (vebrato) of the automatic transmission 2 in test and be determined with N/R device.
Be provided with multiple gear mesh in the inside of the gearbox of automatic transmission 2 and support bearing of the running shaft of each gear etc., in order to complete inspection, the automatic transmission 2 after the assembling of these gear equities completes links its input shaft and output shaft respectively after the assigned position that is positioned substrate plate 3 with input shaft combination apparatus 4 and output shaft combination apparatus 5.
In the time having started to check, based on the control signal control motor 7 and the automatic transmission control apparatus ATCU that carry out self-check control gear 6, carry out performance test and the gear noise test etc. of automatic transmission 2.
The various signals of the state of the automatic transmission 2 while having represented to check to 6 inputs of inspection control gear, for example, check control gear 6 by representing that the pulse signal of rotating speed of output shaft and the acceleration signal of the vibration of the automatic transmission 2 that expression is detected by laser vibrometer 8 are input to.
Acceleration signal from laser vibrometer 8 is also input to abnormity determining device 10 via inspection control gear 6, and the vibration (vebrato) that abnormity determining device 10 specifically completes the automatic transmission 2 in inspection according to the acceleration signal based on this input judges that automatic transmission 2 has or not extremely.
Below, the formation of specification exception decision maker 10.
Fig. 2 is the piece figure of abnormity determining device 10.
Fig. 3 is that explanation is as the figure of cutting apart under the frequency range of detected object and the third-octave unit of this frequency range of abnormality juding.
Fig. 4 is the figure of explanation vibration data and benchmark vibration data.
See that automatic transmission 2 has abnormal situation or the abnormal agnogenic situation of the automatic transmission 2 that is extremely associated with this etc. under, the sound of this situation message of loudspeaker 50 output notices.
CPU20 possesses: vibration data acquisition unit 21, benchmark vibration data generating unit 22, abnormality juding portion 23, data supplementing portion 24, reason particular portion 25, notice control device 26, registration portion 27.
The acceleration signal of vibration data acquisition unit 21 based on inputting from inspection control gear 6 obtains the vibration data of the timeliness variation of the vibration that represents automatic transmission 2.This vibration data obtains at each frequency band of having cut apart using the frequency range of regulation as the frequency range of the detected object of abnormality juding.
In mode of execution, the sense of hearing that is set at people as the frequency range of the object of abnormality juding can be served as sound and the frequency band (zone of audibility) of perception, and vibration data becomes each frequency band of the frequency range of this zone of audibility and obtains having cut apart with third-octave.
In order, using the vibration of automatic transmission 2 as voice capturing, to use the corresponding people's of third-octave sense of hearing sense.
In addition, in the following description, the frequency band of having cut apart using third-octave as the frequency range of zone of audibility is labeled as to " benchmark frequency band ".
At each benchmark frequency band, the vibration data group based on being stored in memory section 30 generates the benchmark vibration data that abnormality juding is used to benchmark vibration data generating unit 22.
Particularly, because vibration data group is made up of multiple vibration datas, change so obtain the timeliness of the mean value of the vibration acceleration calculating according to vibration data at each benchmark frequency band.And, change the benchmark vibration data that generates the timeliness variation that stipulates the vibration acceleration (vibration acceleration CLV ceiling limit value) that becomes the upper limit according to the timeliness of the mean value of obtaining.
In mode of execution, obtain vibration acceleration CLV ceiling limit value (μ+3 σ) according to the standard deviation of the average value mu of vibration acceleration, vibration acceleration, and generate the benchmark vibration data of the variation of the timeliness that has stipulated this vibration acceleration CLV ceiling limit value at each benchmark frequency band.
As shown in Figure 4, in the situation that vibration data in the past distributes in the scope of shade in the drawings, timeliness at the mean value of obtaining vibration acceleration according to all vibration datas in past changes after (solid line representing with mean value in reference to Fig. 4), the benchmark vibration data (double dot dash line representing with CLV ceiling limit value in reference to Fig. 4) changing in the timeliness of each benchmark frequency band generation regulation vibration acceleration CLV ceiling limit value.
In mode of execution, this benchmark vibration data is obtained in each CF center frequency of having cut apart the frequency band of the frequency range that becomes zone of audibility (benchmark frequency band) with third-octave.Such as, in other benchmark frequency band (4000Hz, 5000Hz etc.) beyond the benchmark frequency band that is therefore, 3150Hz in CF center frequency, also can similarly generate benchmark vibration data.
For example, in the case of certain gear mesh of automatic transmission have assembling abnormal, produce than the large vibration (vebrato) of vibration (vebrato) of anticipation in the part of this gear mesh.Therefore,, in the case of finding than the large vibration (vebrato: vibration acceleration) of the vibration (vebrato: vibration acceleration CLV ceiling limit value) that becomes the upper limit, be judged to be finding that this abnormal benchmark frequency band has extremely.
Therefore, the in the situation that of Fig. 4, between moment t1～t2, the vibration acceleration of vibration data exceedes by benchmark vibration data set upper limit value, and therefore, the benchmark frequency band that to be judged to be in this CF center frequency be 3150Hz has extremely.
In addition, abnormality juding portion 23 does not have abnormal in the situation that being judged to be automatic transmission 2, the vibration data of inputting from vibration data acquisition unit 21 is input to data supplementing portion 24, has abnormal in the situation that being judged to be automatic transmission 2, vibration data is outputed to reason particular portion 25.
At this, vibration data is to be judged as the vibration data while inspection that completes that there is no abnormal automatic transmission 2, the interior existence of memory section 30 complete passed examination the vibration data of automatic transmission part.
Therefore, complete passed examination in the past automatic transmission more, the vibration data that is contained in vibration data group is more, therefore, the benchmark vibration data being generated by this vibration data group generates in view of the real data in past, the reliability of benchmark vibration data improves.
In addition, vibration data is distinguished and is stored by each Test item (performance test described later and gear noise test etc.) of having carried out the kind of the automatic transmission that completes inspection and complete in inspection.
For example, the kind of automatic transmission is 100 kinds, in the situation that Test item is two, adds up to 200 vibration data groups to be present in memory section 30.
In addition, vibration data also can be distinguished and store by completing the environmental factor (temperature, humidity, time period) while checking and each factory or the each production line that completes inspection.
Impact that can be by environmental factor and carried out completing the deviation of the data that the difference etc. of the factory etc. of inspection causes reflects in benchmark vibration data, therefore, can more correctly be determined with without abnormal.
Reason particular portion 25 in the case of be judged to be the above-mentioned automatic transmission completing in inspection have abnormal, based on having found abnormal benchmark frequency band and having found abnormal moment, number of times etc. (being generically and collectively referred to as below abnormal item) and with reference to abnormal cause table 32, confirmed having or not of the corresponding abnormal reason of the item abnormal with this.
Abnormal cause table 32 is described.
In abnormal cause table 32, abnormal item and abnormal reason are registered accordingly.
For example, for example, certain time period midway of the speed change since 1 speed to 2 speed (from speed change 30 seconds), in the situation that benchmark frequency band 3150Hz has exceeded CLV ceiling limit value, the mode producing take this abnormal reason as assembling due to certain gear mesh has item (abnormal item) and abnormal reason when abnormal to store accordingly at abnormal cause table 32 by being judged to be automatic transmission.
Therefore, with reference to abnormal cause table 32, judge abnormal reason (or candidate of abnormal reason) by the abnormal item based on producing.
The correspondence of the abnormal item in abnormal cause table 32 and abnormal reason has been found out the result of reason and has generated in view of the abnormal each situation that has produced vibration (vebrato) for completing of past in inspection.
Therefore, have abnormal in the situation that being judged to be automatic transmission 2, reason particular portion 25 is based on determining the abnormal item (vibration data) that produces in abnormal automatic transmission and with reference to abnormal cause table 32, in the case of existing corresponding abnormal reason, the data that represent this abnormal reason are outputed to notice control device 26.In addition, in the case of not existing corresponding abnormal reason, the message of this situation is outputed to notice control device 26.
For example, in the time representing the data of specific abnormal reason from 25 inputs of reason particular portion, generate the instruction being used for notifying by Word message or sound signal by the specific abnormal reason of these data.
In addition, be not present in abnormal cause table 32 in the abnormal reason corresponding with abnormal item, generate the instruction for this situation message is notified by Word message or sound signal.
In the case of worker notice is had abnormal and abnormal agnogenio true, impel the specific of this abnormal reason.
In addition the program that the CPU20 execution that, above-mentioned vibration data acquisition unit 21, benchmark vibration data generating unit 22, abnormality juding portion 23, data supplementing portion 24, reason particular portion 25, notice control device 26, the each function block of registration portion 27 possess by abnormity determining device 10 is stored in not shown ROM and memory section 30 realizes.
Below, illustrate automatic transmission manufacturing line complete inspection operation, the processing of the abnormality juding in specification exception decision maker 10 simultaneously.
Fig. 5 has illustrated the flow chart that checks operation.
Fig. 6 is that explanation judges with the abnormal sound that the each test that completes inspection operation is carried out abreast the flow chart of testing.
Check in operation completing of mode of execution, with the parallel abnormality juding test of carrying out the vibration (vebrato) based on automatic transmission of the each test that completes inspection of automatic transmission (parallel).
First, check in operation completing, by after having completed the input shaft of automatic transmission 2 of assembling of gear equity part and output shaft link with input shaft combination apparatus 4 and output shaft combination apparatus 5 respectively in unit assembling procedure, start the performance test (step 101) of automatic transmission.
Confirm to check according to the information of operating condition that represents the automatic transmission in this performance test whether the automatic transmission of object brings into play predefined performance and regular event (step 102) whether.
And (step 102: normal (OK)), carries out gear noise test (step 103) in the situation that this performance judgment is not pinpointed the problems.
In addition, complete and check in operation at this, test execute exception noise abreast with performance test and gear noise and judge test, in performance test and gear noise test, carry out respectively the N/R judgement that has of automatic transmission based on vibration (vebrato).
Therefore,, the in the situation that of no abnormal in gear noise test (step 104: normal), in step 105, in judging test with the abnormal sound of performance test and gear noise test execution abreast, be confirmed whether to be judged to be abnormal.
In abnormality juding test, being judged to be (step 105: no) in N/R situation, finish inspection operation.
On the other hand, in abnormality juding test, be judged to be abnormal in the situation that, to carry out production line action (step 106) and abnormal causal investigation operation (step 107), and item based on abnormal is carried out abnormal causal investigation, specific.
In addition, the in the situation that of noting abnormalities in performance test (step 101) and gear noise test (step 103) (step 102:NG or step 104:NG), also carry out production line action (step 106) and abnormal causal investigation operation (step 107), and make a service test and the abnormal causal investigation of gear noise in testing, specific.
In addition, reason extremely, again implement performance test and gear noise test for the automatic transmission of the abnormal reason of automatic transmission having been carried out to counter-measure in the case of specific, test execute exception noise abreast with these simultaneously and judge test.
And, the in the situation that of all not noting abnormalities, finished inspection operation in any test.
Secondly, the flowchart text abnormal sound based on Fig. 6 is judged test.
First,, in the time starting abnormal sound judgement test, vibration data acquisition unit 21, according to the waveform of the output signal of laser vibrometer 8, is obtained the vibration data (step 201) of the variation of the timeliness that represents vibration acceleration at above-mentioned each benchmark frequency band.Therefore, example as shown in Figure 4, each CF center frequency of each benchmark frequency band obtain become figure in the vibration data of the waveform that represents of solid line.
In the time obtaining vibration data, the vibration data (vibration data group) in past of benchmark vibration data generating unit 22 based on being stored in memory section 30 asked for the mean value of the vibration acceleration calculating according to the vibration data in multiple past timeliness at each benchmark frequency band changes.Then, change according to the timeliness of the mean value of obtaining, generating regulation at each benchmark frequency band becomes the benchmark vibration data of the timeliness variation of the vibration acceleration (vibration acceleration CLV ceiling limit value) of the upper limit.
Thus, generate the benchmark vibration data (double dot dash line being represented by CLV ceiling limit value in reference to Fig. 4) of the timeliness variation of regulation vibration acceleration CLV ceiling limit value at each benchmark frequency band.
In the time generating benchmark vibration data, abnormality juding portion 23, at relatively vibration data and benchmark vibration data of each benchmark frequency band, judges that each benchmark frequency band has or not (step 203) extremely.
In mode of execution, in the case of being had the part that exceedes vibration acceleration CLV ceiling limit value by the specific vibration acceleration of vibration data, being judged to be has at this benchmark frequency band extremely.
When be judged to be all not have (step 204: no) when abnormal under any benchmark frequency band, data supplementing portion 24 will be appended to memory section 30 from the vibration data that is judged to be not have abnormal automatic transmission to obtain.Thus, be contained in vibration data group vibration data increase by one.Therefore,, in the abnormality juding test after next time, the quantity of the vibration data while generating benchmark vibration data increases.
When being judged to be after any benchmark frequency band has extremely (step 204: be), whether reason particular portion 25 is based on having found the vibration data of abnormal benchmark frequency band and having confirmed and be present in abnormal cause table 32 by the corresponding abnormal reason of the specific abnormal item of vibration data with reference to the abnormal cause table 32 in memory section 30.
In the case of there being (step 207: be) abnormal reason, notify control device 26 to generate for exporting for notifying abnormal generation and the Word message of its reason and the instruction of acoustic information, and it is exported to display unit 40 and loudspeaker 50.Thus, notify abnormal generation and its reason (step 208) to worker.
On the other hand, in the case of not there is not (step 207: no) abnormal reason, notice control device 26 generates for exporting for notifying abnormal generation and the abnormal agnogenio true Word message of message and the instruction of acoustic information, and it is exported to display unit 40 and loudspeaker 50.Thus, notify abnormal generation and its agnogenio true message (step 209) to worker.
Thus, by the above-mentioned production line action (step 106) and the investigation operation (step 107) that check in operation (with reference to Fig. 5) of completing, based on investigating abnormal reason by the specific abnormal item of vibration data.
At this, in mode of execution, the frequency range of object that becomes abnormality juding is set in can be using people's the sense of hearing as sound and the frequency band (zone of audibility) of perception, and different frequency range (third-octave) unit that can vibrate by sound discrimination with people's the sense of hearing obtains vibration data.
Therefore, in the case of completing automatic transmission in inspection notes abnormalities, again implement to have found abnormal test, worker can grasp the abnormal sound now producing in automatic transmission by the sense of hearing of self, also can contribute to the specific of abnormal position.
In addition, in the case of specific the abnormal reason corresponding with abnormal item, can be via operation inputting part 60, the corresponding relation of abnormal item and abnormal reason is registered to abnormal cause table 32.
Therefore, notifying after abnormal agnogenio true message, input the situation of corresponding relation of abnormal item and abnormal reason from operation inputting part 60, in the abnormal cause table 32 of memory section 30, appended the data (step 111) of the corresponding relation that has stipulated abnormal item and abnormal reason.
At this, laser vibrometer 8 in mode of execution is equivalent to the vibration detection device in invention, vibration data acquisition unit 21 and step 201 are equivalent to the vibration data acquisition device in invention, benchmark vibration data generating unit 22 and step 202 are equivalent to the benchmark vibration data generating apparatus in invention, abnormality juding portion 23 and step 203 are equivalent to the abnormity determining device in invention, data supplementing portion 24 and step 206 are equivalent to the data supplementing device in invention, and memory section 30 is equivalent to the storage device in invention.
And then reason particular portion 25 and step 205 are equivalent to the abnormal cause specific device in invention, notice control device 26 and step 208 and step 209 are equivalent to the notifying device in invention.
As mentioned above, in mode of execution, a kind of abnormity determining device 10 is provided, it has judged abnormal in the automatic transmission 2 of inspection according to the vibration (vebrato) that completes the automatic transmission 2 in inspection, and be configured to and possess: laser vibrometer 8, its detection completes the vibration of the automatic transmission 2 in inspection; Vibration data acquisition unit 21, its with third-octave unit become the frequency range (zone of audibility) of the object of abnormality juding each benchmark frequency band obtain the vibration data that the timeliness that represents vibration that detected by laser vibrometer 8 changes; Benchmark vibration data generating unit 22, its vibration data group based on being stored in memory section 30 generates at each benchmark frequency band the benchmark vibration data that abnormality juding is used; Abnormality juding portion 23, it compares vibration data and benchmark vibration data at each benchmark frequency band, be determined with without abnormal at each benchmark frequency band, in the time that any one benchmark frequency band notes abnormalities, the automatic transmission 2 being judged to be in inspection has extremely, in the case of all benchmark frequency bands are no abnormal, the automatic transmission being judged to be in inspection does not have abnormal; Data supplementing portion 24, it will be appended to the vibration data group that is stored in memory section 30 from the vibration data that is judged to be not have abnormal automatic transmission 2 to obtain.
By such formation, the timeliness of the vibration (vebrato) based on completing the automatic transmission 2 in inspection changes to be determined with without abnormal, therefore, compare the only peak value based on vibration (vebrato) and be determined with N/R situation, can more correctly be determined with without abnormal.
In addition, be appended to vibration data group from the vibration data that is judged to be not have abnormal automatic transmission 2 to obtain, therefore,, along with the number of units of having carried out the automatic transmission that completes inspection increases, the vibration data of the generation of the benchmark vibration data of using for abnormality juding increases.Thus, increase for the vibration data of the generation of benchmark vibration data, thereby the precision of benchmark vibration data increases, and therefore, can more correctly have N/R judgement.
At this, possess in the automatic transmission of multiple gear mesh, decide the frequency band of the duty of shaking (vebrato) producing from the mate of gear according to the engagement number of times of gear, therefore, in the noise test of existing automatic transmission, only specific frequency band inspection is had to the abnormal of friction (vebrato).
Therefore, only can check that the specific part (gear mesh) that predetermines produces abnormal, in the case of vibration (vebrato) compound action producing from the multiple gear equities in automatic transmission, judge that as automatic transmission entirety vibration (vebrato) is as abnormal, can not tackle.
Not only the frequency range of the object that becomes abnormality juding is limited to specific frequency band, but also is set as all zones of audibility, therefore, can judge that automatic transmission entirety has the abnormal of friction (vebrato).
As automatic transmission, the device of manufacturing at multiple precision partss such as the multiple gear mesh of assembling and bearings, be difficult to vibrate according to which part prediction in advance of device abnormal that (vebrato) brings, what particularly the compound effect of the vibration (vebrato) of the part in device brought is extremely more difficult to anticipation.Therefore,, when the frequency range of object that becomes abnormality juding is only limited to specific frequency band, can not detect the abnormal of these anticipation difficulties.
As mentioned above, be set as all zones of audibility by not limiting the frequency range of the object that becomes abnormality juding, also can detect abnormal (the not specific exceptions noise) of envisioning difficulty.
In addition, at present, abnormal the having or not that the vibration (vebrato) of automatic transmission brings is that worker judges by the sense of hearing, and therefore, the deviation of worker's judgement (deviation of threshold value) is on there being N/R judgement to bring impact.
As above-mentioned formation, vibrate vibration data that the timeliness of (vebrato) changes and there is no being relatively determined with without abnormal of benchmark vibration data that the vibration data group of abnormal automatic transmission generates from being judged as the past by expression, thus, can further there is quantitatively N/R judgement, therefore, there is the reliability of N/R judgement to improve.
In addition, at present, the N/R judgement that has of being undertaken can be replaced with to the method for judging based on data by the sense of hearing, therefore, can carry out the not quantitative evaluation management of specific exceptions noise.In addition, owing to being accumulated about the information of specific exceptions noise not, so can be in initial reply automatic transmission manufacturing process.
Store abnormal cause table 32 at memory section 30, this abnormal cause table 32 is stored according to the corresponding relation of the specific abnormal item of the vibration data of having found abnormal benchmark frequency band and abnormal reason.
Also be configured to and possess: reason particular portion 25, its in the case of be judged to be automatic transmission 2 in inspection have abnormal, based on having found the vibration data of abnormal benchmark frequency band and having carried out the reason of specific exceptions with reference to abnormal cause table 32; Notice control device, it,, by pointing out at display unit 40, export as acoustic information from loudspeaker 50 specific abnormal reason as Word message etc., is given notice to worker.
By such formation, the abnormal cause table 32 based on being stored in memory section 30 carrys out the reason of specific exceptions, and notifies specific abnormal reason via display unit 40 etc.
Therefore,, have abnormal automatic transmission in adjustment is judged to be to complete inspection time, worker can promptly know the position that needs adjustment.
Be configured to and also possess registration portion 27, it does not exist the abnormal item of corresponding abnormal reason and the corresponding relation of new abnormal reason in the case of inputting via operation inputting part 60, and abnormal item and new abnormal reason are registered in abnormal cause table 32 accordingly.
By such formation, can wait promptly to notify to have produced to worker not have the abnormal of corresponding abnormal reason.In addition, in the case of specific reason extremely, specific abnormal reason and the corresponding relation that produces this item (abnormal item) when abnormal are re-registered in abnormal cause table 32, therefore, in the case of after the automatic transmission of carrying out complete inspection in detect same abnormal the reason of specific exceptions rapidly.
Benchmark vibration data generating unit 22 forms as follows, the timeliness of asking for the mean value of the vibration acceleration calculating according to the multiple vibration datas that form vibration data group at each benchmark frequency band changes, and stipulates according to the timeliness variation one-tenth in next life of the mean value of obtaining the benchmark vibration data that the timeliness of the vibration acceleration (vibration acceleration CLV ceiling limit value) that becomes the upper limit changes.
In abnormity determining device 10, carry out completing while inspection of automatic transmission at every turn, do not have the vibration data of abnormal automatic transmission to be appended in the vibration data that forms vibration data group by being judged to be, thereby the female group while generating benchmark vibration data increase.
Therefore, by formation as above, generate the benchmark vibration data in view of the inspection real data in past, therefore, can have or not extremely in view of the inspection data judging in past.
Frequency range is set the frequency band (zone of audibility) that can serve as sound perception for people's the sense of hearing,
Benchmark frequency band is the frequency band of having cut apart the frequency range (zone of audibility) of the object that becomes abnormality juding with third-octave.
Third-octave is that people (worker) can differentiate the minimum unit as the vibration of sound with ear, and therefore, to being judged to be abnormal automatic transmission, worker carries out sense of hearing judgement in addition, can detect thus abnormal position.
A kind of abnormality determination method is provided, judged automatic transmission 2 abnormal of inspection according to the vibration (vebrato) that completes the automatic transmission in inspection, wherein, obtain the vibration data of the timeliness variation of the vibration that has represented the automatic transmission in inspection at each benchmark frequency band of having cut apart the frequency range (zone of audibility) of the object that becomes inspection with the frequency range of regulation, the benchmark vibration data used of abnormality juding that the vibration data getting and the vibration data group based on being stored in storage device are generated compares at above-mentioned each benchmark frequency band, when in the time that any one benchmark frequency band notes abnormalities, the automatic transmission being judged to be in inspection has extremely, when no abnormal in all benchmark frequency bands, the automatic transmission being judged to be in inspection does not have abnormal, to be appended to the vibration data group that is stored in storage device from the vibration data that is judged to be not have abnormal automatic transmission to obtain.
By such formation, the timeliness of the vibration (vebrato) based on completing the automatic transmission 2 in inspection changes to be determined with without abnormal, therefore, compare the only peak value based on vibration (vebrato) and be determined with N/R situation, can more correctly be determined with without abnormal.
In addition, owing to being appended to vibration data group from the vibration data that is judged to be not have abnormal automatic transmission 2 to obtain, so along with the number of units of having carried out the automatic transmission that completes inspection increases, the vibration data of the generation of the benchmark vibration data of using for abnormality juding increases.Thus, because the vibration data of the generation for benchmark vibration data increases, thereby the precision of benchmark vibration data increases, and therefore, can more correctly have N/R judgement.
At this, completing of automatic transmission checks performance test and the gear noise test with automatic transmission, and be configured to, use the abnormal sound of the abnormality determination method of mode of execution to judge test and performance test and gear noise test execution abreast, completing in inspection, all no abnormal in judging test and judge any test of test with the abnormal sound that gear noise test is carried out abreast in performance test and gear noise pass the test and with the abnormal sound that performance test is carried out abreast, complete automatic transmission in inspection qualified.
By such formation, completing inspection with automatic transmission existing carries out abreast abnormal sound and judges test, therefore, can not change significantly existing operation and the equipment that completes inspection, and can have N/R judgement based on vibration (vebrato).
In mode of execution, example detect the situation of the vibration of automatic transmission 2 with laser vibrometer 8, as long as but can export vibrational waveform, also can adopt other vibration detection device.
