Mostly the feature dimension detection of all kinds of workpieces is whether to exceed design or the scope of technological design (roughing) tolerance of permission for its mismachining tolerance, judges the credit rating of work pieces process with this and disposes foundation.The precision workpiece of the most large quantities of a large amount of high-efficiency and continuous processing, generally requires and entirely examines the product after processing.Therefore, this kind of detection without understanding and to record its actual error amount be how many, and be actually needed be the accuracy rating of detection and high efficiency that detection operates.Based on this thinking, the workpiece sorting gauge head of the present invention is provided with measurement 6 and spacing thimble 3, and when measurement 6 contacts spacing thimble 3, the display lamp 14 in testing circuit sends signal, shows that detected size reaches capacity (upper poor or allowance below nominal size).And, spacing thimble 3 is connected with sleeve pipe 8 by fine thread, and screw thread uses less helical pitch so that workpiece sorting gauge head has the highest accuracy of detection, can reach below 0.005mm.
The on-line measuring device of the present invention is applicable to either simplex sequence grinding, is also applied for multiple operation (including corase grind, half fine grinding and fine grinding) grinding；May be used for bistrique and compensate the on-line checking of timing it can also be used to the on-line checking of grinding eyeglass (or workpiece) quality.
In conjunction with Fig. 1, Fig. 3 referring to Fig. 4, it, when bistrique compensates on-line checking, can follow the steps below:
1) the follow-up operating side at grinding station 31 arranges detection station 32, and the on-line measuring device of the nearside a set of present invention of configuration at detection station, detection for grinding rear lens, to determine the opportunity that bistrique compensates, measurement 6 should be made when being arranged on line detector the most corresponding with the lens gripper axle center of detection station 32 respectively, in order to measure a 6 alignment eyeglass center and carry out the measurement of grinding thichness；
2) governor motion described in actuating, the position of spacing thimble 3 is adjusted, the scale 9 on turn handle 2 is made to make zero, the standard specimen eyeglass of grinding process it is built at lens gripper, described standard specimen eyeglass refers to the standard eyeglass of the median thickness according to grinding process technological design, such as, the technological design thickness of this operation grinding eyeglass is A ± a, then the thickness of standard specimen eyeglass should be [A]=[(A+a)+(A-a)]/2=A (mm)；When some workpiece or eyeglass are according to the needs of fit dimension, and in its technological design, difference is asymmetric with allowance below nominal size, such as (A+a, A-b), then the thickness of standard specimen eyeglass should be [A]=[(A+a)+(A-b)]/2 ≠ A(mm).Then the fluid cylinder 22 of on-line measuring device is started, make measurement 6 decline, and make its lower end and standard finished products lens contacts, close down fluid cylinder 22 when display lamp is bright, now stop nut 24 described in turn is allowed to be in close contact with described support plate 21, then is locked by locking nut 25；
3) start fluid cylinder 22 and mention gauge head 6, then set grinding wheel feed compensation dosage by described governor motion according to the bistrique of tested grinding process and promote described spacing thimble 3, for the eyeglass that precision instrument is supporting, general grinding wheel feed compensation dosage is about 0.01 ~ 0.02mm, i.e. lens thickness after grinding adjusts more than or equal to reply bistrique decline minimum restraining position during this grinding wheel feed compensation dosage in time with the upper difference of standard specimen thickness [A]；
4) start equipment for grinding and carry out eyeglass grinding, it is sampled detecting to the eyeglass completing grinding according to the frequency set, according to being ground the soft, crisp, soft, firmly different of eyeglass material, 50 ~ 100 eyeglasses of general grinding need to adjust grinding wheel feed amount to compensate once, but in view of the present invention on-line checking speed quickly, in order to ensure eyeglass grinding quality, may be set to grinding 20 ~ 30 detect once, it is beneficial to reduce the abrasion measuring head, the service life of extension detection device.When gauge head decline based on stop nut 24 spacing put in place after display lamp 14 still do not work, then illustrate that the eyeglass of grinding is in the margin of tolerance of technological design, it is not necessary to carrying out the compensation of grinding wheel feed amount, grinding can be normally carried out；Not yet put in place and time display lamp 14 is shinny when gauge head spacing decline based on stop nut 24 puts in place or declines, then illustrate that the lens thickness of grinding the most maybe will be beyond the margin of tolerance of technological design, i.e. should stop grinding, adjust, according to setting compensation amount, the lower position that bistrique declines.
Carry out the detection of grinding lens thickness according to the method described above, to select to determine the opportunity that grinding wheel feed amount compensates, owing to detection speed is exceedingly fast, 2 ~ 3s is the most only needed to complete, moreover carry out when not stopping grinding operation, thus the efficiency of grinding process is not affected.Secondly, according to the method described above detection device is adjusted, the upper difference that the error of grinding eyeglass can be made to allow far below technological design, is greatly improved the grinding accuracy of eyeglass.Certainly, the above-mentioned 3rd) in step, also described spacing thimble 3 can be promoted according to the upper difference close to grinding eyeglass technological design thickness, the most suitably strengthen grinding wheel feed compensation dosage, so can reduce the frequency of grinding wheel feed compensation adjustment in the case of ensureing grinding accuracy, shorten the accumulative compensating operation time, improve the production efficiency of grinding process.
In conjunction with Fig. 1, Fig. 3 referring to Fig. 5, the on-line measuring device of the present invention can also be used for the on-line checking of grinding (or processing) quality, its method is based on the judgement to product tolerance extreme value, in most cases, as long as the actual size of product all belongs to certified products in the range of error allowed, and without understanding in detail or recording its actual size value.Whether finished product actual size can be made in the range of design allowable error and judging accurately by the on-line measuring device of the present invention, and be achieved in product quickly check judgement, so being particularly well-suited to the inspection of a large amount of Continuous maching product.The method that crudy judges can sequentially include the following steps:
