实施例1：Example 1:
请参阅图1-3，一种高导向性新型金刚石钻头，一种高导向性新型金刚石钻头，包括导向钻套1和配合钻把2，导向钻套1一端连接有导向钻筒3，配合钻把2一端连接有冲击钻头4，配合钻把2安装于导向钻套1内，冲击钻头4安装于导向钻筒3内。Please refer to Fig. 1-3, a new type of diamond drill bit with high steerability, a new type of diamond drill bit with high steerability, including a
冲击钻头4包括钻头本体41以及连接于钻头本体41端部的定位尖42和助切环尖43，且定位尖42位于助切环尖43的内侧中心处，钻头本体41作为主体提供冲击力，定位尖42主要起到定位导向的效果，助切环尖43采用尖角设计更有利于划破板材表面保证钻孔更容易切入，同时起到清角的作用。The
导向钻筒3上开设有与冲击钻头4相匹配的排屑槽，导向钻筒3端部靠近排屑槽处连接有减阻刃5，导向钻筒3端部远离排屑槽处连接有去毛刺刃6，减阻刃5主要作用是使刃口更锋利减小切削阻力，增加排屑的流畅性，去毛刺刃6采用反面角加尖角设计使得加工出的产品切口整洁，表面无毛刺不爆边。The
请参阅图4-5，导向钻套1内表面开设有多个均匀分布的桥接槽，桥接槽内镶嵌连接有相变充填包9，导向钻套1内开设有环形预警腔10，导向钻套1内还开设有多组连通于环形预警腔10与相变充填包9之间的迁移孔，迁移孔内滑动连接有预警棒8，且预警棒8延伸至相变充填包9内，相邻的相变充填包9之间连接有电热丝12，导向钻套1外端镶嵌连接有气体传感器11，且气体传感器11的测量端延伸至环形预警腔10内，配合钻把2上开设有多个均匀分布的充填孔7。Please refer to Fig. 4-5. A plurality of evenly distributed bridging grooves are formed on the inner surface of the
请参阅图6-7，相变充填包9包括连接于桥接槽内的形变膜91和填充于形变膜91内的充填珠92和助密实块93，形变膜91起到包裹充填珠92和助密实块93的作用，而充填珠92和助密实块93可以配合起来对充填孔7进行高密实度的填充，并基于相变特点进行断开和连接。Please refer to FIGS. 6-7 , the phase
配合钻把2内镶嵌安装有电磁铁，充填珠92采用磁性材料制成，通过配合钻把2内的电磁铁对充填珠92进行吸附，从而迫使充填珠92带动形变膜91进行形变主动寻找对应的充填孔7，并进行高密实度的填充。An electromagnet is installed in the
充填珠92具有多种尺寸，且充填珠92的总体体积大于充填孔7的体积，充填珠92的尺寸不一可以利用级配特点提高密实性，并更加容易对冲击钻头4传递来的冲击力进行多点密集的分散，有效改善震动问题，充填珠92需要满足在填充完充填孔7之后仍有余量存在桥接槽内，从而在相变后提高导向钻套1和配合钻把2连接处的强度。The filling
助密实块93采用热熔性树脂材料和导热石墨粉混合制成，且质量比为1:0.5-1，热熔性树脂材料在一定的温度下会熔化为流动相，冷却后重新恢复为固相，导热石墨粉不仅可以提高热熔性树脂材料的密实性，从而提高固化后的机械强度，同时可以快速均匀的导热，提高相变的反应即时性。The densification-assisting
预警棒8包括连接于迁移孔靠近相变充填包9一端开口处的堵漏环81以及相互连接的磁吸头82和预警管83，且磁吸头82连接于预警管83靠近相变充填包9的一端，堵漏环81一方面对预警管83进行导向移动，另一方面对迁移孔进行密封，避免助密实块93反向进入到迁移孔内导致充填孔7内填充密实度不够，进而降低导向钻套1和配合钻把2之间的连接强度，磁吸头82同样可以响应电磁铁的磁吸作用，迫使预警管83进入到相变充填包9内，不仅可以挤压助密实块93进入到充填孔7内充填珠92的缝隙内，提高密实程度，同时可以预留在剩余的助密实块93内，提高助密实块93固化后的强度，并提供预警作用。The
预警管83采用玻璃材质，预警管83内侧填充有混合有色粉末的易挥发材料，预警管83在受到一定的冲击力后会发生碎裂现象，可以提前间接感知到冲击钻头4的震动偏移，从而释放出内部的易挥发材料，气体传感器11在感受到气压变化后可以及时提示技术人员，有色粉末也有利于技术人员直接观察到，并且可以根据有色粉末判断偏移点，从而针对性的进行调整和维修。The
充填孔7可以为沿孔口方向先窄后宽的任意孔型，先窄后宽可以有效避免相变后的相变充填包9与充填孔7之间的径向偏移，可以充分提高连接后的强度。The filling
本发明可以实现创新性的采用导向钻套1与配合钻把2之间的配合，基于磁吸技术和相变充填包9的相变特点，在转变为液体流动相时，迫使相变充填包9发生形变主动靠近并进入到配合钻把2上预设的充填孔7中，然后通过预警棒8的作用提高填充的密实效果，然后重新转变为固相进行桥接，有效对导向钻套1和配合钻把2进行高强度的定位连接，从而间接提高冲击钻头4在工作时的导向性，极大的减弱径向震动和横向震动，并在发生偏移初期，利用预警棒8的易碎特点提前感知到偏移，然后碎裂释放出内部的易挥发材料，从而及时对技术人员进行预警，有利于及时作出调整和维修，减少精度偏差带来的损失，生产出更为优质的产品。The present invention can realize the innovative use of the cooperation between the
