【摘要】：薄壁軸承套圈是軸承零件系列中壁厚較薄的一種,其檢測精度要求極高。在成品測量過程中,現(xiàn)有的軸承專用檢測儀器存在一定的局限性,第一,可能會由于套圈的彈性變形得不到準確的測量結果;第二,傳統(tǒng)的接觸式測量可能會對軸承表面造成劃傷,影響產(chǎn)品質(zhì)量;第三,受測量原理的限制,無法一次完成多個參數(shù)的測量。因此,為了能夠得到更加準確的測量結果,需要開發(fā)一種新型測量儀器,完成薄壁軸承套圈的高精度測量。本文以薄壁軸承的非接觸測量儀器和非接觸測量方法為研究對象,在理論研究的基礎上,利用誤差分離技術、計算機技術以及OpenGL圖像技術,對測量軟件框架、測量系統(tǒng)、圖形重構等內(nèi)容展開研究。對薄壁類精密零件的特性做了分析,并對其測量手段、圓柱度誤差的分離計算方法進行了對比分析,最終將三點法作為研究重點以及新型儀器的測量方法。按照非接觸測量的要求和三點法測量原理,擬定了薄壁軸承外徑非接觸測量儀的測量方案,并對YZD-400型圓柱度測量儀進行了改造,使之適用于三點法測量。利用C#語言在Microsoft Visual Studio2010環(huán)境下編寫了圓柱度誤差的分離計算軟件,生成可操作的界面,軟件包含運動控制、數(shù)據(jù)采集、誤差分離、圖形重構等功能,并利用OpenGL圖形技術重構出圓柱體形貌特征。最后進行了實驗測量,經(jīng)過對標準件圓度誤差的多次測量,結果與標準件所標注精度一致,又與原裝傳感器做了對比測量實驗,兩者的測量結果相互符合,證明了新型儀器達到了所要求的測量精度,滿足了測量需求。該儀器的成功研制對于檢驗薄壁套圈類產(chǎn)品質(zhì)量,有效地提高產(chǎn)品合格率,具有一定的應用價值。
[Abstract]:Thin-wall bearing ring is a kind of thin wall thickness in bearing parts series, and its detection precision is very high. In the process of measuring the finished product, the existing special measuring instruments for bearing have some limitations. First, the elastic deformation of the ring may not get accurate measurement results; second, The traditional contact measurement may cause scratches on the bearing surface and affect the product quality. Thirdly, the measurement of multiple parameters can not be completed at a time because of the limitation of the measuring principle. Therefore, in order to obtain more accurate measurement results, it is necessary to develop a new measuring instrument to complete the high-precision measurement of thin-walled bearing rings. This paper takes the non-contact measuring instrument and non-contact measuring method of thin-walled bearing as the research object. On the basis of theoretical research, using error separation technology, computer technology and OpenGL image technology, the measurement software frame and measurement system are analyzed. Graphics reconstruction and other contents of the study. The characteristics of thin-walled precision parts are analyzed, and the measuring methods and the calculation methods of the cylindrical error are compared and analyzed. Finally, the three-point method is taken as the focus of the research and the measuring method of the new instrument. According to the requirements of non-contact measurement and the principle of three-point measurement, the measuring scheme of the non-contact measuring instrument for the outer diameter of thin-walled bearing is worked out, and the YZD-400 type cylindrical measuring instrument is modified to be suitable for three-point measurement. Using C # language in Microsoft Visual Studio2010 environment, the separation and calculation software of Cylindricity error is written, which can generate an operable interface. The software includes the functions of motion control, data acquisition, error separation, graph reconstruction, and so on. The shape of the cylinder was reconstructed by OpenGL technique. Finally, the experimental measurement is carried out. After several measurements of the roundness error of the standard parts, the results are consistent with the precision of the standard parts, and the results are compared with those of the original sensors. The results of the two measurements are in accordance with each other. It is proved that the new instrument achieves the required precision and meets the requirement of measurement. The successful development of the instrument has certain application value for testing the quality of thin-walled ring products and effectively improving the qualified rate of products.
