【摘要】：目的精密軸承性能與軸承球體表面質(zhì)量密切相關(guān),表面的精密快速檢測對于保證軸承球體質(zhì)量非常重要,因而提出一種適用于在線光學(xué)檢測的新球體全展開方法。方法分析目前已提出的幾種球體全展開方法,并指出它們在實際應(yīng)用中的不足,對新的展開機構(gòu)的展開原理進行分析,并進行了理論分析推導(dǎo)。建立了新的展開機構(gòu)模型,通過Adams軟件虛擬仿真,并通過設(shè)定不同的仿真參數(shù),探究不同參數(shù)對球體全表面展開檢測軌跡的影響。將子午線檢測和螺旋線檢測時光斑的覆蓋率做了對比。結(jié)果新機構(gòu)可實現(xiàn)球體均勻全覆蓋展開,適于激光散射和干涉這種光斑面積較小的檢測方法,全覆蓋時間受進動和轉(zhuǎn)動速度的影響。進動速度一定時,主軸轉(zhuǎn)動速度越大,螺旋線間距越大,不影響全覆蓋時間;主軸轉(zhuǎn)動速度一定時,進動速度越大,螺旋線間距越小,全覆蓋時間越短。在仿真時間為15 s、主軸轉(zhuǎn)動速度為400(°)/s的情況下,得到最優(yōu)進動速度為12(°)/s。結(jié)論對于新的球體展開機構(gòu),通過對轉(zhuǎn)動和進動速度以及聚焦位置的調(diào)整,可實現(xiàn)對不同直徑球體表面的均勻全覆蓋檢測。
[Abstract]:Objective the precision bearing performance is closely related to the surface quality of bearing ball. The rapid and accurate surface detection is very important for ensuring the quality of bearing ball. Therefore, a new sphere full deployment method suitable for online optical inspection is proposed. Methods several spheroid full deployment methods have been analyzed, and their shortcomings in practical applications are pointed out. The deployment principle of the new deployable mechanism is analyzed, and theoretical analysis and deduction are carried out. A new deployment mechanism model is established, through Adams software virtual simulation, and by setting different simulation parameters, we explore the influence of different parameters on the detection trajectory of the whole surface of the sphere. The coverage rate of the time spot detected by the meridian detection and the spiral line detection is compared. Results the new mechanism can achieve uniform uniform coverage, which is suitable for laser scattering and interference. The full coverage time is influenced by precession and rotation speed. When the precession speed is constant, the greater the spindle speed is, the greater the distance between the helical lines will not affect the total coverage time. When the spindle speed is constant, the larger the precession speed is, the shorter the distance between the helical lines is, and the shorter the total coverage time is. When the simulation time is 15 s and the rotation speed of the spindle is 400 (degree) /s, the optimal precession speed is 12 (degree) /s. Conclusion for the new sphere deployable mechanism, the uniform coverage of spheres with different diameters can be achieved by adjusting the rotation and precession speed and the focusing position.
