毕业设计（论文）--弹簧弹性力测试分选机.docVIP

摘 要 弹簧弹性力测试分选机是对大批量生产的弹簧依据其弹性系数不同，按照预先规定的指标进行测试自动筛选出合格与不合格产品，并在不合格产品范围内依据是否可以修复将弹簧进一步细分，自动流入不同的装料箱，以用于不同场合。随着计算机技术的发展，弹簧分选系统用电子控制技术代替机械式的分选系统，大大提高了分选系统的速度和准确性。 本文就弹簧分选的原理、系统任务分配、硬件控制系统的结构及软件设计等几方面进行了论述。 本文对弹簧分选机的工作原理做了详细说明。硬件控制器部分采用MCS-51单片机为主控制器，进行适当扩展与丰富的外围设备。成功的设计了气动回路和电机的驱动模块。根据实验结果，分选部分可以安全精确的把弹簧送到预定的地点。AD采集模块采用8位逐次逼近式采集芯片ADC0809。CPU控制程序在汇编语言环境下实现。 本课题的完成，为研发低成本的弹簧分选设备提供了思路。 关键词：弹簧分选；低成本；MCS-51单片机；AD采集；汇编程序设计 Abstract Automatic spring classification machine is the machine that can test large quantities of springs, which have different flexibility coefficients and used for the different situation, and sieve automatically the qualified different from the unqualified according to the rules proceeded in advance, also further subdivide the spring coil according to whether can repair within the scope of the unqualified, automatically afflux anticipate box. With the development of computer technology, the traditional mechanical method was replaced by electronic technology; the new method improves the accuracy and the speed of the systemic. Automatic spring classification method, the structure of control system and its application software design are all discussed in this paper. The automatic spring classification method was introduced in detail in this paper. Control hardware system adopts MCS-51 as the principal machine, we proceed the propriety of the enlarge to make communication with the periphery equipment. The successful pneumatic return circuit of design and drive module of the printer. The experiment result expresses, the sending parts designed can send the spring coil to the measured position safely, dependably and accurately. The block of A/D gather built with the chip of ADC0809, which made in USA by Intel. The source program was built on the environment of Compile Language. Accomplishment of this task offered new fashion for designing lower cost spring classification device. Key Words: Spring classification； Low cost； MCS-51 MCU； Compile Program
