隨著精密機械發展快速以及自動化生產技術的進步,所生產的加工產品精度也相對提高,因此人工檢測方式已經漸漸被自動化檢測所取代,現今較常利用雷射以及機械視覺的檢測方式來取代傳統檢測方式。 本文主要建立三套量測系統,使用雷射二極體與四象限光電二極體建立一套旋轉軸量測系統,用以量測成型主軸水平和垂直方向傾斜角度誤差,此系統具有架設容易等優點;使用雷射位移計和數位量錶等建立一套真圓度及垂直度量測系統,用以量測攜帶圈真圓度、攜帶圈垂直度及攜帶圈夾塊真圓度,此系統具有操作方便及量測範圍廣等優點;使用雷射二極體與CCD等建立一套旋轉軸量測系統,用以量測鋼帶成型筒水平和垂直方向傾斜角度誤差,相較於雷射二極體搭配四象限光電二極體,有成本低和量測範圍廣等優點。 本系統在成型主軸量測部分,其解析度為0.2角秒;在攜帶圈真圓度和垂直度量測部分,其解析度為0.01mm;在攜帶圈夾塊真圓度量測部分,其解析度為1.5μm;在鋼帶成型筒量測部分,其解析度為1.2角秒。經實驗顯示,成型主軸水平方向傾斜角度誤差為-28.5角秒,垂直方向傾斜角度誤差為-31.3角秒;攜帶圈真圓度為0.148mm,攜帶圈垂直度為0.061mm,攜帶圈夾塊真圓度為0.398mm;鋼帶成型筒水平方向傾斜角度誤差為29.4角秒,垂直方向傾斜角度誤差為32.4角秒。 由上述結果可證實,本研究所開發的三套量測系統,可應用於成型機多項誤差量測,藉以提供現場人員進行機台校正。
With the rapid development of precision machinery and automated production technology advances, the processing accuracy of products are relatively enhance. Thus automatic detection method has been gradually replaced by manual inspection. Now, traditional detection methods are replaced by laser and machine vision detection methods. In this paper, to establish three kinds of measurement system. Using diode laser and quadrant photodiode make up a rotation axis measurement system for measuring horizontal and vertical inclined angle errors of spindle molding, to set up easily is advantage for the system; using a laser displacement meter and digital indicator to establish roundness and verticality measurement system for measuring carried ring' roundness, verticality and roundness of carried ring block, the advantage of this system is easy to operate and has a wide range of measurement; using diode laser and CCD to establish a measurement system of rotation axis for measuring horizontal and vertical inclined angle errors of steel forming tube, to compare with the diode laser and quadrant photodiode, the advantages of system is less cost and has wide range of measurement. In spindle molding measurement system, its resolution is 0.2 arcseconds; in roundness and verticality measurement system of carried ring, its resolution is 0.01mm; in roundness measurement system of carried ring block, its resolution is 1.5μm; in steel forming tube measurement system, its resolution is 1.2 arcseconds. The final answer is that the spindle error for the horizontal angle of inclination is negative 28.5 arcsenconds, and the vertical angle of inclination is negative 31.3 arcseconds. The roundness and verticality of the carried ring is 0.148 mm and 0.061 mm. The roundness for the carried ring block is 0.398 mm. The error of the horizontal and verticality inclination angle for the steel forming tube is 29.4 arcseconds and 32.4 arcseconds. This research is developed three measurement system. Can be used in molding machine error measurement. Thereby providing on-site staff calibration machine.
