【摘要】：除锈钢刷专用生产设备是专门用于生产除锈钢刷的自动化机械设备，在除锈钢刷的自动化加工设备的设计开发过程中有着异常重要的作用。机械设备的自动化程度直接关系到企业的经济效益和工人劳动力的节省。自动化程度高的专用生产设备不仅可以提高生产效率还可以有效地增强钢刷的除锈性能。本文着眼于除锈钢刷专用生产设备各个功能模块的结构设计和动力学的分析研究。分别从以下几点进行论述：（1）对除锈钢刷现有的机械加工设备的工作原理进行分析和研究。对除锈钢刷专用生产设备的两种整体结构设计方案进行分析对比，然后研究了设备整体的动力传递路线和各执行件的驱动方式，并以此为依据确定了本文的整体结构设计方案和各个功能模块的机构组成和动力传递方式。阐述了机械设备的整体结构，在原有机械的基础上，改进了其压入方式，增加了锁口模块、尾部扎紧模块和尾部切平模块。最后，按各个动作执行件的动作要求，绘制机械运动循环简图。由于，除锈钢刷的加工工艺较复杂，设备的执行机构多，为了让分析和设计更清晰、明了，本文以各个功能模块为单元进行设计、分析。（2）用Pro/ENGINEER软件以各个功能模块为单元建立了各自的主要零部件模型，其中包括：槽轮机构和凸轮机构的设计。凸轮本文采用参数化设计，先用解析几何法求得凸轮轮廓曲线的各重要参数，再对虚拟模型进行参数化设计，使其可实现参数化再生，以利于轮廓曲线的修改。用虚拟装配技术同样以各功能模块为单元将零部件组装起来，验证各零部件的设计尺寸合理。（3）建立各功能模块的数字样机，添加材料属性、驱动属性、约束属性，建立各功能模块的功能虚拟样机进行并进行运动仿真，验证了各个零部件之间没有出现运动干涉现象，凸轮轮廓曲线设计合理，不会出现自锁，执行件能按机械运动循环简图的设计要求完成周期动作。同时，还对锁口模块的增力连杆机构做增力性能分析，，分析在输入一定转矩的情况下，锁口机构能够输出足够的冲压力使工件达到完全锁紧的目的。最后将设备整体模型总装起来，以机械运动循环简图为依据，设定各功能模块驱动件的相对位置，做整体的运动仿真，验证各模块间能相互配合完成除锈钢刷的生产动作。
[Abstract]:The special production equipment for rust removing steel brush is a kind of automatic mechanical equipment which is specially used to produce rust removing steel brush. It plays an extremely important role in the design and development of the automatic processing equipment for rust removing steel brush. The degree of automation of mechanical equipment is directly related to the economic benefit of enterprises and the saving of labor force of workers. The special production equipment with high degree of automation can not only improve the production efficiency but also enhance the rust removal performance of steel brushes. This paper focuses on the structural design and dynamic analysis of each functional module of the special production equipment for rust removing steel brush. The main contents are as follows: 1) the working principle of the existing machining equipment for rust-removing steel brush is analyzed and studied. This paper analyzes and compares two kinds of integral structure design schemes of the special production equipment for rust removing steel brush, and then studies the power transfer route of the whole equipment and the driving mode of each actuator. Based on this, the whole structure design scheme, the mechanism composition and the power transfer mode of each function module are determined. The whole structure of the mechanical equipment is expounded. On the basis of the original machinery, the indentation mode is improved, and the lock port module, the tail fastening module and the tail cutting flat module are added. Finally, according to the action requirements of each action executive, draw the mechanical motion cycle diagram. Because the processing technology of rust-removing steel brush is more complex and the equipment has many executing agencies, in order to make the analysis and design more clear and clear, this paper designs each functional module as the unit. The main parts models of each functional module are established by using Pro-ENGINEER software, including the design of grooving wheel mechanism and cam mechanism. In this paper, the parameterized design of cam is adopted. The important parameters of cam contour curve are obtained by analytic geometry method, and then the parameterized design of virtual model is carried out, which can realize parameterized regeneration, which is beneficial to the modification of contour curve. Using the virtual assembly technology, the components are also assembled with each functional module as the unit to verify that the design size of each component is reasonable. (3) to establish the digital prototype of each functional module, to add material attribute, drive attribute, constraint attribute, etc. The function virtual prototyping of each function module is established and the motion simulation is carried out. It is verified that there is no movement interference between the parts and components, the cam contour curve is designed reasonably, and the self-locking does not occur. The actuator can complete the periodic action according to the design requirements of the mechanical motion cycle diagram. At the same time, the force enhancement performance of the force-enhancing link mechanism of the lock port module is analyzed, and it is analyzed that the locking mechanism can output enough punching pressure to make the workpiece achieve the purpose of complete locking under the condition of input a certain torque. Finally, the overall model of the equipment is assembled, based on the mechanical motion cycle diagram, the relative position of each functional module driver is set up, and the whole motion simulation is done to verify that each module can cooperate with each other to complete the production of rust-removing steel brush.
