柔性化微喷带激光打孔夹具的设计

Design of Flexible Micro-spraying Laser Drilling Fixture

针对厚度1.2mm以下的软质微喷带在激光打孔过程中存在的易变形、调试繁琐和对中操作不便等问题,专门设计了一套柔性化程度高和通用性强的微喷带激光打孔定位夹具。该夹具主要由支撑机构、对中机构和防打透机构3部分组成。通过实验改进,能够保证带宽在100mm以内微喷带的精确定位和对中,实现了微喷带动态在线速度57m/min的连续精密打孔,达到了预期的生产效果,适应微喷带的产业化发展要求,且为同类型零件的加工夹具设计提供了参考。

Aiming at the problems of easy deformation, complicated debugging and inconvenient operation the laser drilling process for the soft micro-spray belt with the thickness of 1.2 mm or less, a set of micro-spray belt laser drilling positioning fixture with high flexibility and versatility is designed. The fixture is primarily composed of a support mechanism, a centering mechanism and an anti-penetration mechanism. Through experimental improvement, it can ensure the precise positioning and alignment of the micro-spray belt with the bandwidth within 100 mm, and realize the dynamic continuous precision drilling of the micro-spray belt with a dynamic on-line speed of 57 m/min,which achieves the expected production effect and is suitable for the industrialization development requirements of the micro-spay belt, and serve as a reference for the processing fixtures design of the same type of parts.
