The invention relates to a manual large-diameter optical fiber cutting knife, which comprises a frame, an optical fiber clamp and a knife head assembly. The optical fiber clamp is divided into a dynamic clamp and a static clamp. The frame panel is provided with a linear guide rail, which is connected with the base of the dynamic clamp. The frame bottom plate is provided with a one-dimensional linear platform, a moving plate is arranged on the one-dimensional linear platform, and a pressure tester is arranged on the mobile plate. The push rod of the pressure tester is in contact with the end face of the base of the movable fixture. The advantages of the present invention are as follows: a set of dynamic fixtures and static fixtures are arranged on the frame and driven by a one-dimensional linear platform, so that the optical fiber can maintain a certain tension force while pressing. The tension force is displayed by a pressure tester. The new structure is simple and the operation is convenient. The fast clamping of the optical fiber and the online display of the tension force are realized, and the cutting quality of the optical fiber is guaranteed. Cutting of optical fibers from 125um to 1250um.
【技术实现步骤摘要】
一种手动大纤径光纤切割刀
本专利技术属于通信
,特别涉及一种手动大纤径光纤切割刀。
技术介绍
光纤切割刀用于切割像头发一样细的光纤,切好光纤经数百倍放大后观察仍是平整的,才可以用于器件封装、冷接、和放电熔接。现有光纤切割刀采用单独的光纤夹具,夹具上的压盖同时夹紧光纤的两端,适应于:单芯或多芯石英裸光纤,适应光纤包层直径范围:φ100-250um,由于其压紧力有限,切割过程容易出现光纤端面不齐、切不断,且不适用大纤径的光纤切割,急需一种能够保证光纤切割质量、适用大纤径的光纤切割刀。
技术实现思路
本专利技术的目的在于克服现有加工技术中压紧力有限,造成光纤端面切割不齐、切不断的问题,提供一种手动大纤径光纤切割刀。为实现上述目的,本专利技术采用以下技术方案:一种手动大纤径光纤切割刀,包括机架、光纤夹具和刀头组件,所述机架面板上设有光纤夹具和刀头组件,所述光纤夹具分为动夹具、静夹具,静夹具固定在机架面板一端,动夹具相对静夹具可以做直线移动,所述刀头组件设置在动夹具、静夹具之间。所述机架面板上开设有方孔,方孔底面设有直线导轨,直线导轨与动夹具底座连接,动夹具可在方孔内移动;所述机架底板上设有一维直线平台,一维直线平台上设有移动板,移动板上设有压力测试仪,压力测试仪的推杆与动夹具底座的端面接触配合。本专利技术的有益效果是:在机架上设置一组动夹具、静夹具,通过一维直线平台推动,使得光纤在压紧的同时维持一定的张紧力,张紧力的大小由压力测试仪显示,可以根据不同直径的光纤设定相应的张紧力大小。本新型结构简洁,操作方便,实现了光纤的快速夹紧,张紧力在线显示,保证了光纤切割质量 ...
