【摘要】：随着机械自动化的发展,装配过程的自动化的作用越来越重要。自动化装配的重要目的是提高生产效率、降低装配成本、稳定与改善产品质量、减轻劳动强度以及取代特殊条件下的人工装配劳动。轴承是机械工业使用广泛、要求严格的配套件和基础件,被人们称为机械的关节。轴承装配过程中的浪形轴承保持架正反面自动分离这一环节,目前,仍没有有效的解决方案,基本上是人工分离,不利于装配自动化的实现。为了实现浪形轴承保持架正反面自动分离,以及一些与浪形轴承保持架相类似的具有正反形状特征的导磁性零件的自动分离,本文设计了一种新的电磁增强式离心分离装置,并利用Pro/e软件对离心分离装置的各个部件进行了建模。其工作原理是离散分单的保持架输送到离心分离装置的底盘工作台上并随工作台旋转到磁极下方时,受到惯性离心力、摩擦力和电磁力的作用,由于保持架的正反面形状不同,使保持架的正反面受到的电磁力大小不同,也就是保持架正反面受到的摩擦力不同。调节电机的转速,可以改变惯性离心力的大小。通过比较保持架正反面受到的惯性离心力和摩擦力的大小关系,实现保持架正反面的自动分离。为了验证离心分离方法的可行性,利用Pro/E软件对此装置的关键部分建模,并导入Ansys有限元仿真软件中,对保持架正反面受到电磁力的大小进行了仿真分析,分析结果验证了离心分离装置的可行性。离心分离装置只是初步的开发设计,需要更进一步的优化,这样才更能保证了轴承自动化装配过程中的实时性、效率性、经济性,同时也为一些与浪形轴承保持架相类似的其他零件的正反面自动分离提供了依据和方法。
[Abstract]:With the development of mechanical automation, the automation of assembly process is becoming more and more important. The important purpose of automatic assembly is to improve production efficiency, reduce assembly cost, stabilize and improve product quality, lighten labor intensity and replace manual assembly labor under special conditions. Bearings are widely used in the mechanical industry, demanding strict accessories and basic parts, known as mechanical joints. At present, there is still no effective solution for the automatic separation of the front and back faces of the wavy bearing cage in the process of bearing assembly, which is basically manual separation, which is not conducive to the realization of assembly automation. In order to realize the automatic separation of the front and back surfaces of the wave bearing cage and some magnetic conductive parts with positive and negative shape similar to the wave bearing cage, a new electromagnetic enhanced centrifugal separation device is designed in this paper. Pro/e software is used to model the components of centrifugal separation unit. The operating principle of the cage is that when the cage is transported to the platform of the centrifugal separator and rotated to the bottom of the magnetic pole with the table, it is subjected to the action of inertia centrifugal force, friction force and electromagnetic force, due to the different shapes of the front and back sides of the cage. The electromagnetic force on the front and back sides of the cage is different, that is, the friction force is different between the front and back sides of the cage. Adjusting the speed of the motor can change the size of the inertia centrifugal force. By comparing the relationship between the inertia centrifugal force and the friction force on the front and back sides of the cage, the automatic separation of the front and back sides of the cage is realized. In order to verify the feasibility of centrifugal separation method, the key parts of the device are modeled by Pro/E software, and the magnitude of electromagnetic force on the front and back sides of the cage is simulated and analyzed by using the Ansys finite element simulation software. The analysis results verify the feasibility of centrifugal separation device. Centrifugal separation device is only preliminary development and design, need further optimization, so as to ensure the real-time, efficiency and economy of bearing automatic assembly process. At the same time, it also provides the basis and method for automatic separation of the front and back surfaces of some other parts similar to the wave bearing cage.
