摘　　要：动力工具通常带有套筒和接杆,为避免操作工在紧固操作过程中直接接触旋转的套筒和接杆,设计了既安全又便于安装的热塑性聚氨酯(TPU)套筒接杆护套小总成。针对套筒接杆护套小总成,运用SolidWorks和Teamcenter软件进行3D建模与整车环境虚拟评估;利用3D打印技术制备TPU试样,通过正交试验方法分析打印工艺参数对试样硬度和拉伸性能的影响,得到了较为理想的套筒接杆护套小总成3D打印工艺参数组合:打印层高0.2 mm,壁厚1.2 mm,打印温度220℃,打印速度35 mm·s^(-1)。在该优化工艺条件下打印的套筒接杆护套小总成满足使用要求。Power tools usually come with sleeves and extensions.To avoid direct contact between workers and rotating sleeves and extensions during fastening operations,a thermoplastic polyurethane(TPU)sleeve and extension sheath small assembly was designed to be both safe and easy to install.For the sleeve and extension sheath small assembly,SolidWorks and Teamcenter softwares were used for 3D modeling and virtual assessment of the vehicle environment.TPU samples were trial-produced using 3D printing technology,and through the orthogonal experimental method,the influence of printing process parameters on the hardness and tensile properties of the samples was analyzed,and an ideal combination of 3D printing process parameters of the sleeve and extension sheath small assembly was obtained:printing layer height 0.2 mm,wall thickness 1.2 mm,printing temperature 220℃,and printing speed 35 mm·s^(-1).The sleeve and extension sheath small assembly printed under this process condition met the usage requirements.
