【正文】 port, has occupied a very important position in people39。s action is achieved by the cylinder during operation in the roller touches the limit switch is triggered PLC controls the motor, thus boosting the flip frame and rotating frame rotating, to achieve the engine block production line process. The graduation thesis contains flip frame of the motor, the motor rotating frame, roller motor OK. The main design of the flip frame transmission parts, transmission parts and rotating frame roller drive. And one of the gears, sprockets, bevel gear and to determine the size of the material, and checked. Second, the design of the PLC control of the ladder and the external wiring diagram, the final design of the pneumatic clamping device. Flip the engine block production line with rotating mechanism is the most basic tool for engine production line, which has a simple structure and high efficiency. Automatic process can not only reduce the labor intensity of the work and improve productivity. Can be said that 汽車發(fā)動機缸體翻轉(zhuǎn)機構(gòu)設計 4 the engine block production line with rotating mechanism is turning ordinary automobile manufacturing industry is the ideal tool. Keywords: engine block production line flip, rotate institutions PLC 汽車發(fā)動機缸體翻轉(zhuǎn)機構(gòu)設計 5 目錄 摘要 .................................................................................................................................................. 2 Abstract ........................................................................................................................................... 3 目錄 .................................................................................................................................................. 5 1 本課題的研究現(xiàn)狀、研究目的及意義 ............................................................................................ 6 內(nèi)外研究現(xiàn)狀 .................................................................................................................... 6 研究目的及意義 ................................................................................................................. 6 本課題主要研究內(nèi)容 .......................................................................................................... 7 2 電動機的選擇 ............................................................................................................................... 9 確定發(fā)動機缸體主要參數(shù) ................................................................................................... 9 輥道電動機 ........................................................................................................................ 9 翻轉(zhuǎn)架電動機 .................................................................................................................... 9 旋轉(zhuǎn)托盤電動機 ................................................................................................................. 9 電機尺寸的確定 ............................................................................................................... 10 3 傳動件設計 ................................................................................................................................ 12 齒輪設計 ......................................................................................................................... 12 齒輪材料，熱處理方式和精度等級 ........................................................................ 12 按齒根彎曲疲勞強度初步計算齒輪參數(shù) ................................................................. 12 確定傳動尺寸 ........................................................................................................ 13 校核齒面接觸疲勞強度 .......................................................................................... 14 旋轉(zhuǎn)架圓錐齒輪傳動設計 ................................................................................................. 15 齒輪材料及其精度等級 .......................................................................................... 15 精度等級 ............................................................................................................... 15 齒輪參數(shù) ............................................................................................................... 16 確定傳動尺寸 ........................................................................................................ 17 校核齒根彎曲強度 ................................................................................................. 18 鏈傳輸設計 ...................................................................................................................... 19 鏈式輸送機的工作原理 .......................................................................................... 19 鏈條設計
