【摘要】：随着市场竞争的日趋激烈,劳动力成本的增加,国内各企业争相开展自动化设备的研发,用先进的自动化设备替代传统的人工作业方式。目前,在各大中型企业中,工业机器人被广泛应用于搬运、焊接、喷涂、装配等大劳动劳动和工作环境恶劣的场合,但对部分中小型企业而言较高成本的工业机器人不符合中小型企业自身的实际生产需求,故仍有部分中小企业中依旧采用传统的人工作业方式,工作环境恶劣,劳动强度大,生产效率低下,次品率较高。特别在危险程度较大,工作环境较恶劣的冲压车间,存在着部分中小型企业依旧采用传统的人工手动操作进行坯料和成品的上下料,随着《中华人民共和国新劳动法》的颁布和实施,“用工荒”和“招工难”的问题进一步凸显,自动化程度较低的部分中小型企业急需对现有设备进行升级改造并引进低成本的自动化设备。本课题所研发的机械手臆在实现电机硅钢片生产过程中的坯料和成品片自动上下料。鉴于已为电机制造企业开发过一台用于电机定子硅钢片冲压的自动上下料机械手,但在运行过程中存在较多问题,无法适应多型号、小批量电机硅钢片的实际生产需求。本论文依据电机制造企业的实际生产需要和电机硅钢片生产工艺要求,在结合已开发的电机定子硅钢片上下料机械手的实际运行状况的情况下,对机械手进行了大量的改进工作,并在改进定子片冲压生产的上下料机械手的基础上对用于转子片冲压生产的上下料机械手进行了研发。在开发过程中本文从原机械手在结构设计、零件加工工艺、装配及后期维护等方面出发并结合调试和运行过程中遇到的一些列问题,对原机械手的各模块的缺陷和不足以及运行过程中的故障提出了相应的改进或解决方案,并在后续的优化过程中进行了实施和验证,并在此基础上针对电机转子片的冲压过程中的实际需求开发了用于电机转子硅钢片冲压自动上下料机械手。机械手的总体结构设计基于SolidWorks三维建模软件,各零部件的建模和虚拟装配均在该软件下完成;其次,对重要零部件进行了强度和刚度的分析;最后在装配和调试过程中解决现场出现的问题。
[Abstract]:With the increasingly fierce market competition, the increase in labor costs, to carry out research and development of automation equipment, domestic enterprises, with advanced automation equipment to replace the conventional ways of work. At present, the large and medium-sized enterprises, industrial robots have been widely used in handling, welding, spraying, assembly and other large labor and poor working environment on the occasion, but on the part of small and medium-sized enterprises of industrial robot high cost does not meet the actual production needs of small and medium sized enterprises, they still have the traditional work industry still uses part of small and medium-sized enterprises, poor working environment, high labor intensity, low production efficiency, high defect rate. Especially in the larger degree of risk. Stamping workshop environment is bad, there are some small and medium-sized enterprises are still using the traditional manual operation of billet and finished loading, with "the The promulgation and implementation of the people's Republic of China new labor law "," labor shortage "and" recruitment difficult "to further highlight the problems of low degree of automation of small and medium enterprises need to upgrade existing equipment and the introduction of low cost automation equipment. The research and development of mechanical hand in chest dynamosheet in the production process of billet and finished piece automatic feeding. In the light of the motor manufacturing enterprises in the development of a platform for automatic motor stator silicon steel sheet stamping on the manipulator, but there are many problems in the operation process, can not adapt to the multi type and small batch production demand dynamosheet this dissertation. On the basis of motor manufacturing enterprise's actual production needs and dynamosheet production process requirements, motor stator silicon steel sheet has been developed in combination with the actual operation situation of the manipulator on the condition of mechanical hand For a large number of improvements, and improvements in the stator stamping production on the basis of the manipulator on the rotor for sheet stamping production by manipulator are developed. In the process of development from the original mechanical hand in structure design, parts processing, assembly and post maintenance aspects and meet with the debugging and running process of some problems, failure of each module of the manipulator and the insufficiency as well as the operation process and puts forward the corresponding improvement or solution, and has been implemented and verified in the subsequent optimization process, and based on the actual demand for the stamping process of motor rotor the development for automatic manipulator of motor rotor. The overall structure design of silicon steel sheet stamping manipulator based on 3D modeling software SolidWorks, modeling of parts and virtual assembly in the The software is completed under the software; secondly, the strength and stiffness of the important parts are analyzed. Finally, the problems in the field are solved in the process of assembly and debugging.
