Detection technique method and utility machine structure main contents that the present invention adopts are described below:
(1) the detection technique method that adopts workpiece and adapter standard sample to contrast: be called for short " relative method " and detect.The standard that adapter detects is according to the limit of wear that is " railway maintenance procedure " regulation, and abrasion value refers to compare with the original product design size and determine, and judge according to this workpiece qualified, treat Jia Xiu or scrap three kinds of states, and separated.This method is to adopt the accurately standard sample of processing of a process, is called for short standard specimen (Fig. 1), and its material is identical with various adapter with shape, and the size that detects the position is identical with prototype adapter product design figure correspondingly-sized, improves the 1-2 level but make precision.Equipment is at first demarcated standard specimen before to workpiece sensing, and equipment respectively detects the position dimensional data to standard specimen and carries out acquisition process and memory retention; When subsequent workpiece detected, the data of demarcating take standard specimen can obtain the detection numerical value of each workplace abrasion value of workpiece as benchmark compares computing.The superiority of relative method is: one, can directly obtain " railway maintenance procedure " middle workplace abrasion value data that require, and real result is reliable; Its two because that standard specimen is made precision is high, except can detecting each workplace abrasion value, can also detect each workplace change in location situation (being the morpheme error), provide useful information that workpiece quality is controlled comprehensively; When its three pairs of standard specimens are demarcated, also to equipment state, confirm such as the rational position to sensor probe, its essence is the effect nuclear to equipment state, this point is very necessary.The range of the various sensors that equipment adopts is that reference work surface wear limit is determined, requires to make this range as far as possible little, and is not excessive to guarantee enough accuracy and self size, in order to make the detection module miniaturization, anti-locking mechanism is interfered.The position of each sensor probe when the state of demarcation reserves abundant work range (abrasion value), needs to guarantee workpiece sensing, and this work range can be in the timing signal collection, industrial computer screen display, thereby the good working state of the equipment of assurance.
Adopt the prerequisite condition of standard specimen relative method to have: 1. design determines that various adapter " standard sample " detects the standard size at position.When definite standard specimen corresponding site processing dimension tolerance, the female surface size is got the plus tolerance value, and male surface is got the minus tolerance value, and the average error value is less than 5% of the limit of wear value, and surface accuracy improves 1-2 grade than originating in design; Standard specimen saddle face circular arc still adopts " excessively cooperating " with bearing, but dimensional accuracy improves a grade.The standard specimen material adopts former adapter material, can guarantee long-term request for utilization.The detail of design of various adapter standard sample is included " adapter checkout equipment technical conditions " in, through the expert authenticate by.2. it is qualified to detect through national standard metrological service after standard specimen is made, and opens proof, carries out mark.3. adopt the standard specimen relative method to detect, must behind the workpiece location, gather simultaneously the detection data of each workplace, objectively require accurate detent mechanism is set, adopt a centralized detecting station, to guarantee the accuracy of detection requirement.Adopt the standard specimen relative method to detect adapter and proposed by applicant, rolling stock section tried out in east, Chengdu.
(2) adopt the method for measuring the constant chord height, detect saddle face garden arc dia abrasion value, in saddle face circular-arc detection mechanism, be provided with fixedly chord length locating piece, the contact that high-precision sensor is installed in the centre position contacts with the measured workpiece arc surface, measure the height of constant chord, when constant chord left and right sides crest line with after the saddle face contacts, utilize the fixedly slight change of action, can detect saddle face arc diameter numerical value change, x represents action with variable, variable y represents detected arc diameter, 2k represents that fixedly chord length is two crest lines distances of locating piece (See Figure), according to fixing action formula: x/k=k/ (y-x), mathematical function formula: y=x+k is arranged then
2/ x; When x, y get on the occasion of, and meaningful when x＜k, the method is applicable detection to " D type " axletree saddle face (φ 230) and " E type " axletree saddle face (φ 250) abrasion value simultaneously, choose the 2k value and be slightly larger than diameter one half (such as 2k=130mm), be suitable for the detection and location requirement to various model adapters.In practical ranges, the increment size of variable y is about 8-12 times of variable x minimizing value, and the x value is by the high-precision sensor collection, display precision reaches μ m level, the numerical value of y value is pressed mathematical model by the microcomputer calculation process, and with " calibration value " relatively, can finish the detection to saddle face face of cylinder abrasion value.
Judge whether the abrasion of saddle face diameter reach the limit value of rules regulation, require to satisfy two conditions, whether the abrasion of first saddle face are even, the saddle face still is arc surface after the abrasion, it two is whether sensor detection display precision is enough, be described below: the first, the former design size of saddle face " D axle " saddle face diameter y=φ 230
+ 0.10 -0.05And " axle E " saddle face diameter y=φ 250
+ 0.10 -0.05Adopt " transition fit " (9 class precision) with corresponding wheel set bearing cylindrical, according to the bearing working principle, in service, bearing inner ring is " interference fit face " with wheel to axletree, must rotate with axletree at wheel; And cylindrical and saddle face " transition fit " produce the utmost point to relatively rotate slowly in the utilization process, and produce in a small amount even wear, and in the serviceable life that can improve bearing top circle, this is normal.Rules regulation locomotive repair limit is: the abrasion value 0.5mm of saddle face diameter, when near this abrasion value, be equivalent to saddle face dimensional accuracy and be down to approximately 12 grades of dimensional accuracies by 9 class precisions, because outer race abrasion value relative to the saddle face is little, the uniform contact that still can keep the arc surface transition fit, so the saddle face still can keep the geometrical property of circular arc.The second, saddle face displacement transducer selected range is 3mm, and accuracy of detection is 0.1% grade, and its display precision is 0.003mm; When the fixedly chord length 2k=130mm of locating piece, if when action x reduced 0.003mm, the increment of saddle face diameter y was about 0.03mm.The limit value of scrapping by the maintenance procedure regulation is 0.5mm, is feasible if leave 0.05mm synthetic determination error, and visible saddle face examine of diameter accuracy value 0.03mm can satisfy real requirement.
Adopt the high accuracy displacement sensor of small-range, can satisfy simultaneously the detection to D axle (φ 230) and the various adapter saddle face of E axle (φ 250).This case is chord length 2k=130-0.1 fixedly, can satisfy workpiece and accurately locate needs; Owing to adopting fixing chord length to be slightly larger than half of bearing outside diameter, the measured circle cambered surface is contained covered the main support face of bearing working roller, make this scope circular arc quality controlled, can make the contact stress on the bearing roller face of cylinder controlled, prolong the serviceable life of bearing, thereby guaranteed the repair quality of adapter.
