摘要攻丝是机械零部件制造、装配过程中非常重要的一个环节。攻丝可以采用手动攻丝机或者专业的攻丝设备攻丝,一般现在的螺纹孔都是先加工螺纹底孔,然后再在底孔上攻丝。使用传统的攻丝方法,加工过程复杂,攻丝的效率低且耗费劳动力,不利于大批量的加工。因此工厂为了节省劳动力,提高攻丝效率,就发明了高效的自动攻丝机。76448
基于51单片机的自动攻丝机具有操作简单、攻丝效率高、定位准确迅速等优点,避免了传统攻丝工艺上的各种缺点,因此受到了各行各业的广泛应用。研究基于51单片机的自动攻丝机有利于更加深刻的掌握机械、单片机的知识,是非常好的实践,而且能够了解更多的最新行业发展动向。

SCM Control System Of Automatic Tapping
Abstract Tapping mechanical parts manufacturing and assembly process is very important aspect。 Tapping can be used manually or professional tappers tapping tapping equipment, ships are now threaded hole machining starting hole first, and then tapping on the bottom outlet。 Using traditional tapping method, process complexity, low efficiency and tapping labor-intensive,is not conducive to high-volume processing。 Therefore, the factory in order to save labor and improve the efficiency of tapping, invented a highly efficient automatic tapping machine。
51 microcontroller-based automatic tapping machine has a simple operation, high efficiency tapping, fast and accurate positioning, etc。, to avoid the shortcomings of traditional tapping workmanship, it has been widely used in all walks of life。 Based on 51 single-chip automatic tapping machine in favor of a more profound grasp of machinery, SCM knowledge, is a very good practice, but also to learn more about the latest industry developments。
