Description

一种多孔系壳体内腔射流去毛刺专用夹具 技术领域
本实用新型涉及工装夹具技术领域，尤其涉及一种多孔系壳体内腔射流去毛刺专用夹具。
 背景技术
高压液态射流去毛刺技术是利用水力喷射所具有的物理作用和切割作用来去除毛刺的一种柔性加工工艺方法。其原理是利用增压泵对水加压，高压水从特制的喷嘴中喷射出去，压能被转化为动能，产生的高速射流强烈冲击到工件上。如果壁面存在毛刺，则毛刺根部将产生极大的局部应力，足以破坏其结构，毛刺在射流冲击作用下从工件本体上脱落，从而达到清洗目的。相对于现有技术，这种去毛刺工艺具有去毛刺能力稳定、生产效率高、易于实现自动化等优点。
目前，现有的多孔系壳体内腔射流去毛刺夹具仍存在一些不足之处，首先现有的多孔系壳体内腔射流去毛刺夹具夹持效果不佳，现有的多孔系壳体内腔射流去毛刺夹具多是直接控制两个夹持板对多孔系壳体进行夹持，由于多孔系壳体通孔较多且分布不均，使得现有的多孔系壳体内腔射流去毛刺夹具夹持时容易将部分通孔挡住，使得部分通孔无法正常完成去毛刺，从而降低了多孔系壳体内腔射流去毛刺夹具的使用效果；其次，现有的多孔系壳体内腔射流去毛刺夹具缺乏多孔系壳体的位置调节装置，使得在对多孔系壳体不同位面的通孔进行清理时需要不断移动喷嘴，从而降低了多孔系壳体内腔射流去毛刺夹具的便捷性。
