皮囊翻转吊具的设计

目的解决许多圆柱状零件由于缺少吊点,翻转十分困难,且存在单点受力应力集中的缺点,容易对零件造成损伤的问题。方法设计一种皮囊吊具,通过控制气压来调节皮囊和零件间的摩擦力,以夹持圆柱状零件并实现翻转。还通过计算吊具的变形和应力分布,证明该吊具可将单点受力转变为壳体整体受力。结果经过试验验证,该吊具能够成功实现从水平状态翻转到垂直状态以及从垂直状态翻转翻转到水平状态,并且能保持产品的稳定性。结论该设计简单可靠,具有一定的通用性,可供相关设计人员借鉴。

The Design of Rubber-bag Clamp

Objective It is difficult to turn the columned test product without any suspend hole, and stress concentration will lead to damage of the product. Methods This paper designed a new rubber-bag clamp, which could adjust the friction between the rubber-bag and the product to clamp and turn the columned test product. This paper also calculated the distortion and the stress distribution of the clamp, and the result showed that the clamp translated the local force into the global force. Results Through the experimental verification, the clamp could turn the product from horizontal to vertical state or from horizontal to vertical state, and meanwhile keep the stability. Conclusion This design was simple, reliable and generally applicable, which could provide reference for design of similar products.
