一种塑料薄壁壳体零件装夹方案的设计

Design of a Clamping Scheme for Plastic Thin-walled Shell Parts

针对某产品中塑料薄壁壳体零件加工遇到的装夹难题,设计了一副仿形铣夹具,并通过在壳体内腔中浇注石膏填充物,提高了零件装夹时的整体工艺刚度。介绍了装夹设计的思路、基本原理及技术要点。

In order to solve the clamping problem encountered in the processing of plastic thin-walled shell parts in a product, a copy milling fixture is designed. Gypsum fillers are cast in the inner surface of the shell to increase the overall process stiffness when the parts are clamped. This paper introduces the basic principles and technical points of the clamping design.
