Abstract

印刷线路板切割机刀轴,涉及印刷线路板切割机。刀轴由上下螺纹轴、每个螺纹轴上套合的若干个刀片,对锁在每个刀片两侧的锁紧螺母组成,其特征在于:锁紧螺母的轴向厚度为6mm。优点在于:锁紧螺母轴向厚度削减成6mm,两相邻刀片间距缩小到7~8mm,则可切分7~25mm间距切缝的线路板,提高工效。

Description

印刷线路板切割机刀轴
技术领域:
本实用新型涉及印刷线路板切割机,特别是印刷线路板切割机刀轴。
背景技术:
印刷线路板在生产过程中需要在包含有若干个线路板子单元的整板上进行切割切分每个子单元板。切分是在由机架、动力传动机构、刀轴结构、传送结构上进行。刀轴由上下螺纹轴、每个螺纹轴上套合的若干个刀片,对锁在每个刀片两侧的锁紧螺母组成,上下螺纹轴两轴端套合在机架两侧的轴承座上,两轴相向转动由动力传动机构带动。刀轴外螺纹的设计是为了可以按各种线路板切缝间距随机固定刀片,一次性切割可以产生多道切割线。上下刀轴两侧分别设置有双层传送带,线路板由一侧双层传送带夹缝中夹持进给到上下刀片的刀口,上下刀片相向转动切割线路板后,被切分的线路板由后双层传动带夹持送出。
现有刀轴上从两侧将刀片定位的两个对锁的锁紧螺母其单个螺母轴向厚度为25mm,其厚度设计主要从金属刚性来考虑对应于M25外螺纹螺纹轴的强度,但未考虑到被切割的是胶木板材质的印刷线路板,不需要太大的螺母锁紧力。如此设计的结果是相邻两刀片的间距要大于25mm,则无法同时切分小于25mm间距的线路板切缝。但生产中常有小于25mm间距的切缝,只能分两次切分,效率低。
发明内容:
本实用新型的目的在于克服上述缺陷,提供一种印刷线路板切割机刀轴。
本实用新型的方案是:刀轴由上下螺纹轴、每个螺纹轴上套合的若干个刀片,对锁在每个刀片两侧的锁紧螺母组成,其特征在于:锁紧螺母的轴向厚度为6mm。
本实用新型的优点在于:锁紧螺母轴向厚度削减成6mm,两相邻刀片间距缩小到7~8mm,则可切分7~25mm间距切缝的线路板,提高工效。
附图说明:
图1为本实用新型结构示意图。
图2为图1的A-A剖视图。
具体实施方式:
本实用新型由上下螺纹轴3、每个螺纹轴3上套合的若干个刀片1,对锁在每个刀片1两侧的锁紧螺母2组成,其特征在于:锁紧螺母2轴向厚度为6mm。
