【摘要】：针对目前带装球口的深沟球轴承人工装配生产效率低,需求量大的现状,采用经验设计与现代设计相结合的方法,研制一种轴承自动装球机。此装球机应用于轴承内外圈均带有装球口的深沟球轴承的自动装配。利用PLC控制整机进行上料、装球、出料等顺序工作,整个系统可以实现自动运行和故障自诊断等功能。本文的主要工作如下： (1)根据深沟球轴承自动装球机功能要求,逐个分析各个装置动作过程中预定方案以及可能出现的问题,给出各机构的工作原理图,并最终确定各装置的方案和整个动作过程。 (2)在确定设备总体方案的基础上,对自动装球机主要装置包括自动拨球、送球和装球装置,以及其他辅助装置进行具体结构设计,通过气缸驱动各机构完成相应动作,明确各装置相对位置,给出各装置结构图,详细说明工作原理,并利用ANSYS软件验证自动装球机轴承座和机架的强度和刚度是否满足要求。 (3)基于所设计的机械结构,对设备的电气控制系统进行功能分析,选择适合各装置的气缸类型,确定设备的气压传动系统,利用PLC实现设备的自动控制,做出设备运行流程图,给出自动装球机内外圈一次定位开始和第四次压球程序。 该设备已经应用于生产实际,装球成功率可达98%,平均速度为11s/个,降低了工人的劳动强度,提高了该类轴承的装配效率,增加了设备的自动化程度,实现了手工装配到自动装配的转变。
[Abstract]:Aiming at the present situation of low production efficiency and large demand of deep groove ball bearing with ball opening, the method of combining experience design with modern design is adopted. A kind of automatic ball loading machine for bearing is developed. The ball loader is applied to the automatic assembly of deep groove ball bearing with ball port on the inner and outer ring of bearing. The whole machine is controlled by PLC to carry on the sequence work such as feeding, charging and discharging. The whole system can realize the functions of automatic operation and fault self-diagnosis. The main work of this paper is as follows: 1) according to the functional requirements of automatic ball loader for deep groove ball bearings, the predetermined scheme and possible problems during the operation of each device are analyzed one by one, and the working principle diagram of each mechanism is given. Finally, the scheme of each device and the whole action process are determined. On the basis of determining the overall plan of the equipment, the main equipment of the automatic ball loader is designed, including the automatic ball, the ball feeding and the ball loading, as well as other auxiliary devices. Through the cylinder drive each mechanism to complete the corresponding action, determine the relative position of each device, give each device structure diagram, detailed description of the working principle. The strength and stiffness of bearing seat and frame of automatic ball loader are verified by ANSYS software. Based on the designed mechanical structure, the function of the electrical control system of the equipment is analyzed, the type of cylinder suitable for each device is selected, and the pneumatic transmission system of the equipment is determined. The PLC is used to realize the automatic control of the equipment, the flow chart of the equipment operation is made, and the program of the first positioning of the inner and outer ring of the automatic ball loader and the 4th times of ball pressing are given. The equipment has been used in production, the successful rate of ball loading can reach 98, the average speed is 11s / unit, the labor intensity of workers is reduced, and the assembly efficiency of this kind of bearing is improved. The automation degree of the equipment is increased, and the transformation from manual assembly to automatic assembly is realized.
