The present invention also provides for a kind of RODIP chain and swing rod chain method of testing, and it comprises the following steps:
Step one, must do cleaning thoroughly the feature according to technique to test point before test, necessary after having cleaned
Measure at once；
Step 2, makes the equivalent center line of left main frame and right main frame be perpendicular to the operation track of chain, in like manner, makes left cleaning system
The equivalent center line of system and right cleaning systems is perpendicular to the operation track of chain, controls left test main frame and left cleaning systems
Equivalent distances must be exactly equal to the pitch of K chain link (K be exactly the above-mentioned initial value counted down), in like manner, controls right test main
The equivalent distances of machine and right cleaning systems also must be exactly equal to the pitch of K chain link；
Step 3, by the opening of test, the A part of stop sensor centering is placed on RODIP chain number one cross bar (or swing rod chain first
Number fork) at left end root, and the B part of sensor centering is placed on left cleaning systems, under the mechanism that above-mentioned K counts down, really
From the beginning of protecting first chain link of the measurement work number one cross bar from RODIP chain, to the S chain of the J cross bar of RODIP chain
Section end, the regulatory requirement further according to each factory arranges the time cycle of measurement, the time cycle of automatic pure cleaning automatically；Step
Four, when the opening of test, stop sensor are to when starting working after triggering for the first time, and cleaning gets started, and test job
Postponement starts, and starts the work that counts down of K value for the first time.The implication of K is as follows: test main frame is equal to the spacing of cleaning systems
The pitch of K chain link.At the end of counting down, only just get started measurement work；
Step 5, in test process, left and right test host synchronization ground to the chain link of process carry out pitch deformation quantity section by section
Test job, and record in the eeprom memory of main frame.The deformation quantity being once found to have a chain link exceedes marginal value 1,
Main frame is reported to the police, and drives spray equipment to spray labelling on problem chain link；
Step 6, when test open, stop sensor to second time trigger after power cut-off time, cleaning terminates at once, and
Carry out second time K value to count down at once.At the end of second time counts down, just terminate to measure work, and by result after measurement
Passing to the data of PC, input Microsoft Excel carries out reading, analyzing, and finally obtains a result.
Test position must be done before testing and be cleaned thoroughly.On the one hand, because of the knot of chain used by RODIP chain, swing rod chain
The absolute value that structure determines single chain link pitch deformation quantity is less, and therefore, the requirement to certainty of measurement is the highest, generally 0.1 milli
Rice.On the other hand and, because pretreating process causes the equivalent thickness that link surface phosphide deposits, because electrophoresis process causes chain link
The equivalent thickness of surface oil lacquering, has all reached the degree of 1.5 millimeters-3.5 millimeters, thus has defined certainty of measurement and flood
The interference of property.Therefore, test point must be done cleaning thoroughly before test, and, according to the feature of technique, cleaning completes
After must measure at once, it can not be allowed to measure again after running one week, because the interference layer of link surface is often during that week
Have been over the order of magnitude of 0.1 millimeter.
Practical experience teaches that: forever must clean before measurement；And sometimes need only to pure cleaning, it is not necessary to measure.
Such as: if interlude length, the interference of link surface once deposited the thickest, it is necessary to first carry out pure cleaning, limit is carried out after
The operation that cleaning is just measured, to guarantee the precision of test.
In order to further ensure that the precision of measurement, during must avoiding cleaning, part chain link is always subject to than other chain link
The phenomenon that more cleanings process.Because accumulation over time, part is by the chain link of more cleanings, and its test value is often
More smaller than the test value of other chain links, thus have impact on the precision of test.Therefore, it is necessary to take the method counted down to avoid
State embarrassment.Method particularly includes: when the opening of test, stop sensor are to when starting working after triggering for the first time, and cleaning is at once
Start, and test job is postponed starting, and start the work that counts down of K value for the first time.The implication of K: test main frame and cleaning system
The spacing of system is equal to the pitch of K chain link.At the end of counting down, only just get started measurement work.Opening, stop when test
Sensor second time is triggered after power cut-off time, cleaning terminates at once, and carries out second time K value at once and count down.When
At the end of second time counts down, just terminate to measure work.
Test can be carried out the most automatically, it is not necessary to artificially gets involved." one can also be taked when equipment management personnel needs
Keyed " method at once measure or carry out pure cleaning.The most automatically measure and need to design a special timing means, should
Device must be easy to arrange, and must arrange the time cycle of measurement automatically (such as: one according to the regulatory requirement of each factory
Week, surrounding, one month, three months, etc.), the time cycle of automatic pure cleaning.
In order to keep good left and right synchronicity, left main frame must be perpendicular to chain with the equivalent center line of right main frame
Operation track；In like manner, the equivalent center line of left cleaning systems and right cleaning systems also must be perpendicular to the operation rail of chain
Road.Meanwhile, in order to ensure the synchronicity testing main frame with cleaning systems, the equivalent distances of left test main frame and left cleaning systems must
Must be exactly equal to the pitch of K chain link (K be exactly the above-mentioned initial value counted down)；In like manner, right test main frame and right cleaning systems
Equivalent distances also must be exactly equal to the pitch of K chain link.In theory, above-mentioned two perpendicularity and the joint of two K chain links
A redundancy is had in value.In the practical operation of plant site, often utilize this redundancy as the means of checking.This
Rational checking means are provided for installation accuracy.
In test process, left and right test host synchronization ground to the chain link of process carry out pitch deformation section by section and measure
Trial work is made, and records in the eeprom memory of main frame.Once it is found to have the deformation quantity of a chain link more than the first marginal value,
Main frame is reported to the police, and drives spray equipment to spray labelling on problem chain link.
In test process, measured is carried out by telecommunications network in real time by left and right test main frame away from deformation quantity
Relatively, the absolute value of the difference of the pitch deformation quantity of left and right two chain links of the most same sequence number exceedes the marginal value 2 of setting,
Main frame is reported to the police, and drives spray equipment to spray labelling on problem chain link.
By the opening of test, the A part of stop sensor centering is placed on No. 1 cross bar of RODIP chain (or swing rod chain the 1st pendulum
Bar) at left end root, and the B part of sensor centering is placed on left cleaning systems, and under the mechanism that above-mentioned K counts down, just can be really
Guarantor's measurement work is from the beginning of first chain link of the RODIP chain No. 1 cross bar (or No. 1 fork of swing rod chain), to RODIP chain
The S chain section end of J cross bar (or J fork of swing rod chain).Wherein J is total horizontal stroke of whole piece RODIP chain
Bar number (or total fork logarithm of whole piece fork chain), S be chain number between two cross bars of RODIP chain (or
Chain number in one fork pitch of fork chain).
The data of PC it are uploaded to after measuring under such scheme, just can be so that reading, being easy to the order lattice of analysis
Formula is inputted Microsoft Excel by program.In the left area of form, the order from No. 1 cross bar to J cross bar lists each
The left and right pitch deformation quantity of individual cross bar, and both differences.Once cross bar pitch deformation quantity is more than the 3rd marginal value, just with
Yellow color alerts.It addition, the left and right pitch difference of each cross bar has determined that the crooked degree of this cross bar, once exceed and face
Dividing value cross bar exists for, because of the crooked excessively risk that cannot work, just warning with red color.For swing rod chain, it should by above-mentioned
Cross bar pitch makes fork pitch into, and meanwhile, the most left and right fork pitch difference, more than the 4th marginal value, may result in fork card
Dead accident.
In this Microsoft Excel, if the total chain number of chain is N, then the rule of listing of chain link is not to N from 1,
But first chain link in one cross bar pitch of correspondence is to the rule of S chain link.That is: in the right half area of Microsoft Excel,
In corresponding left area in each cross bar pitch first chain link to the deformation quantity of the left and right pitch of each chain link of S, and two
The difference of person.Once the pitch deformation quantity of chain link is more than the first marginal value, just with yellow color alerts.The once left and right pitch of chain link
Difference exceed marginal value 2, just warn with red color.For swing rod chain, above-mentioned cross bar pitch is expressed as fork pitch.
According to the Microsoft Excel of above-mentioned aligned transfer, the problem cross bar (problem fork) in corresponding form, problem chain link,
It become convenient substantially that find the problem cross bar on actual RODIP chain and actual swing rod chain, problem fork, problem chain link.For
RODIP chain, the in situ quantitation management work of swing rod chain provide a great convenience.
In measuring at the scene, measurement process can be caused serious interference effect by the left and right end root of cross bar/fork, and one
The just equivalence of individual root adds a chain link more, and whole piece chain adds up to get off, and the error of chain number/chain link ordinal number often reaches
40-50 saves, and some is even up to 70-80 joint.Such system cannot use at all.Use the signal of optical system imaging, and
Through tight logical calculated, completely solving cross bar/fork root affects a difficult problem for measurement process.
In view of the factor of synchronous head, all of employing imaging method carries out the system of chain link distortion measurement, all uses positive light
Pulse is as the basis measured.But, for the chain link distortion measurement of RODIP chain and swing rod chain, owing to required precision is high
And surface exists the interference layer of flooding property, cleaning systems are essential.And according to the relative property of position, cleaning position must be chain
What son ran meets face, peak, here it is test point.So, test point is exactly in the initial position of shading, and this is with traditional
Use positive light pulse just the opposite as the mechanism of Fundamentals of Measurement, therefore, it is necessary to use negative light pulse as the basis measured.And
The problem that negative light pulse method exists synchronous head interference.Eliminate synchronous head interference by program, the expense of control chip can be increased,
Increase cooccurrence probabilities, can disturbed test work；Increase a control chip and process this problem, then there is this chip and former core
Coordinate synchronization problem between sheet, or can disturbed test work.Therefore, synchronous head interference is eliminated by the method for hardware circuit
It it is a rational method.
In order to improve the stability of whole system, reduce fixing link and the link that communicates as far as possible, therefore, will automatically test institute
Within the timing subsystem needed is arranged in left test main frame, the most additionally it is separately provided.
In order to improve the stability of whole system, all of communication link all uses differential mode amplification circuit.
In order to protect optical system to improve the working life of whole system, two optical systems are all provided with and automatically open
The optical protective cover opening and being automatically switched off.Automatic opening protection function cover when starting to measure, terminates to be automatically switched off protective cover, no when measuring
Need artificial intervention.
In sum, for having there is the nonsynchronous problem of left and right chain or the problem driving engagement to lose efficacy in the present invention
RODIP chain and swing rod chain, the position at problem chain link place can be detected, it is simple to reject problem chain link thus eliminate major accident
Hidden danger is for not yet forming the asynchronous problem of left and right chain or driving RODIP chain and the swing rod chain of engagement Problem of Failure, permissible
By the regular on-line checking of automatization, prevent from forming above two problem, ensure that the long-term steady of RODIP chain and swing rod chain
Fixed operation.
