Description
Technical field
The utility model relates to the Machining of Shaft-type Parts apparatus field, particularly a kind of grinding rod size automatic measurement module.
Background technology
The making of accurate axial workpiece normally processes a kind of bar-shaped blank material earlier, again by technologies such as cuttings, further processes the various characteristic sizes of part.This blank material is called grinding rod, and the dimensional accuracy of himself at first will reach certain technical indicator, could guarantee that like this subsequent technique satisfies the requirement on machining accuracy of part feature size.
Grinding rod is processed as the process of accurate axial workpiece, is normally containing translation shaft (trunnion axis that moves along direction of feed) and be fixed on the translation shaft, be used for that the grinding machine of the rotating shaft (Xuan Zhuan rotating shaft vertically) of clamping bar finishes.Can also utilize the numerical control module that is installed in the computer to be connected with mechanical device, thereby the motion process of above-mentioned translation shaft, rotating shaft is preestablished and operated from a distance.
Grinding rod carries out grinding by centerless grinder to outer surface to be made, and its precision index comprises diameter and the circularity in bar cross section.In the zones of different of bar, there is the minor variations of diameter of section, circularity, when scope that this variation out-of-size allows, form overproofly, do not allow to be directly used in following process; Under the long situation of bar self length, the also corresponding increase of overproof probability appears particularly.Therefore before grinding rod is processed as accurate axial workpiece, need in advance diameter, circularity detection to be carried out in the cross section of bar zones of different, to guarantee that its dimensional discrepancy fluctuation control is within the error range that allows.
In correlation technique, adopt the contact type measurement instrument that the size index of grinding rod is carried out preliminary examination.Yet when these instruments of use, there is following problem: one, the sampling observation point is limited, detects the coverage rate deficiency, and the measurement result degree of accuracy is low; Its two, measurement result is subjected to artificially, subjective factor influences bigger; Its three, the contact probability that improves the bar damage even scrap repeatedly; Its four, operation is loaded down with trivial details, labour intensity is big, efficient is low, the cost height.
The utility model content
Inaccurate, the bar scrappage height of measurement result that causes at existing employing contact tool detection grinding rod diameter and circularity, and cost height, inefficient above-mentioned defective and problem, the purpose of this utility model provide a kind of be installed on the existing equipment, with the noncontact mode automatically operation, faster, the result of measuring speed grinding rod size automatic measurement module more accurately.
For achieving the above object, the utility model provides following technical scheme: a kind of grinding rod size automatic measurement module, it is characterized in that, comprise: gauge head, computing module, described gauge head is arranged in grinding machine and is used for the rotating shaft of clamping bar along the far-end of bar direction of feed, it is by base, and symmetry signal generator, signal receiver mounted thereto formed, the numerical control module that is used for the feeding of control bar in described computing module and the grinding machine is connected, by input port outer signal receiver, described numerical control module is connected with signal generator.
Preferred as technique scheme, the input port of described computing module is connected by netting twine with signal receiver.
Preferred as technique scheme, described computing module is installed in the computer.
Preferred as technique scheme, the vertical height of described signal generator, signal receiver is greater than the diameter of grinding rod.
Grinding rod size automatic measurement module provided by the utility model, can be installed on the existing process equipment and use, change the contactless automatic measurement that realizes for grinding rod diameter and circularity by feeding and the rotation of controlling grinding rod, the overlay length that reads optical signal, and by computer program calculating, analysis to measure result.This module takes full advantage of existing resource, need not to install in addition fully, compares with measurement manually, and its measuring speed is faster, the measurement point coverage rate is wider, reading is more objective, and can avoid damaging bar, and simplifies working process, liberates human resources.Therefore, this automatic measurement module can improve grinding rod dimensional measurement result's accuracy, and is conducive to control cost, raises the efficiency, reduces scrappage.
