摘要: 为提高单进气嘴非接触气爪的吸附性能和气爪结构加工的方便性,根据气爪型腔内部流场特性和3D打印原理,提出了一种基于3D打印技术的旋涡流气爪结构优化设计方案。基于对非接触气爪工作原理的理论分析和气爪型腔内部流场特征的仿真研究,以提高气爪吸附性能为目的对气爪型腔结构进行优化设计,应用3D快速成形加工技术加工出通过仿真计算设计的气爪结构模型。实验结果表明:优化后的气爪型腔产生的负压比优化前负压增大一倍,气爪的吸附力提升57%,在气爪加工方面,采用3D打印技术比传统的机械加工技术更具便捷性,且气爪型腔内部复杂结构更容易被加工出来。

Abstract: In order to improve the absorption capability of the single air-inlet non-contact pneumatic grippers and make the pneumatic gripper structures processing more convenient, based on the features of flow field characteristics of pneumatic grippers and the theory of 3D printing, an advanced swirling flow pneumatic gripper design proposal was developed. Aiming at improving the absorption capability of pneumatic grippers, the model of pneumatic gripper cavities was well designed through simulation analysis of non-contact pneumatic gripper's operational principles and flow field characteristics of pneumatic grippers. The claw structure model was built with 3D rapid prototyping technology and was developed with the simulation calculation design. Experimental results show that the negative pressures by improved pneumatic gripper cavities are twice as high as before.Also, the absorption capability increaseds by 57 %. With respect to the processing of pneumatic grippers, compared with traditional machining technology, 3D printing technology is more convenient and the complicated inner parts of pneumatic gripper cavities may be produced more easily.

Key words: swirling flow, non-contact handling, 3D printing, adsorption performance
