钉扣锁眼一体机的结构设计及仿真分析
Structural Design and Simulation Analysis of Nail Button and Eyelet Integrated Machine

根据市面上现有的钉扣机、锁眼机、振动盘，设计并集成一台具有自动给料装置、自动送料装置、自动定位装置、自动上料装置、自动下料装置和自动收料装置于一体的钉扣锁眼一体机，并用SolidWorks三维建模软件对各装置搭建三维模型。使用ABAQUS有限元仿真软件对机架进行静力学分析，判断机架是否满足设计要求，又对三种不同类型的机架进行模态分析，得到前6阶固有频率与振型，分析了产生不同频率的原因，对以后结构的优化设计具有指导意义。经实践证明，一体机能够实现对衬衫袖口同时完成钉扣和锁眼动作，提高了生产效率，解决了人工上下料的问题，降低工艺成本，符合企业的生产要求。
In accordance with the existing nail button machine, eyelet locking machine and vibration plate on the market, a nail button and eyelet locking machine integrated with automatic feeding device, au-tomatic delivery device, automatic positioning device, automatic loading device, automatic dis-charging device and automatic collecting device was designed and assembled in one machine. Moreover, a 3D model was constructed for each device by means of SolidWorks 3D modeling soft-ware. Based on ABAQUS software to conduct the static analysis of the rack was performed to deter-mine whether the rack meets the design requirements. Modal analysis method is used to analyze from 1st to 6th order natural frequency and vibration mode of the three different type of frame. Analyze the reasons for this situation and it has guiding significance for the optimization design of the structure in the future. After practice, it was proved that the all-in-one machine can realize the simultaneous completion of nail button and locking eyelet action on the shirt cuffs. This improves the production efficiency, addresses the issue of manual loading and discharging, and reduces the process cost, which complies with the production requirements of the enterprise.
