Description

防抱死的内锥钻夹头 技术领域
本实用新型涉及内锥钻夹头。 背景技术
手枪电钻是一种非常常用的电动工具。手紧钻夹头和扳手钻夹头是应用于手 枪电钻中最经典和普遍的钻夹头，但它们会因受到冲击而导致夹持钻具松动， 因 此， 它们在冲击电钻中的应用存在问题。尽管钻夹头的基本结构已经定型， 即使 微小的改进也需付出比较大的心血，但一直以来， 技术人员仍然持着地试图改良 上述经典钻夹头的结构。 比较重大的改进出现在上世纪 90年代， 技术人员终于 找到了如何克服上述钻夹头如何克服受冲击后所夹钻体容易松动的解决办法，即 在上述钻夹头中引入自锁机构，从而克服了电钻受到冲击时容易发生的夹持钻具 松动的问题。
实际上，在自锁式结构应用于手枪电钻的钻夹头之前或同一时期， 在欧美几 个有影响力的钻夹头制造企业也在开发另一种钻夹头， 同样也为了克服上述问 题， 这就是内锥钻夹头。
内锥钻夹头设有与驱动机器配合连接的连接体，连接体的后部设有用于与驱 动机器连接的连接孔， 所述连接体的前端为锥形头并在锥形头上设置有外螺纹， 所述钻夹头还设有可相对连接体转动的钻体，所述钻体套在连接体外， 钻体中设 有围绕连接孔轴线分布的夹爪孔，所述钻夹头的夹爪穿过所述夹爪孔与所述外螺 纹螺纹连接，所述螺纹连接的螺纹为反向螺纹。 由于内锥钻夹头的螺纹是反向螺 纹， 使内锥钻夹头有自紧功能， 其钻具越钻越紧， 这样， 即使受到冲击， 也不会 因此而发生松动，或即使有松动迹象，但马上又因为电钻的工作而被夹紧，而且， 内锥钻夹头相较于同样具有自紧功能的自紧钻夹头， 体积、 重量都要小得多。
上述问题似乎已被内锥钻夹头所解决了， 但实际上还远未结束。
内锥钻夹头的优势所在恰恰是其引发问题的所在，由于内锥钻夹头的钻具越 钻越紧， 再加上工作中金属材料发热膨胀， 使内锥钻夹头与钻具的螺纹结合力越 来越大而产生了抱死现象， 操作人员几乎无法手握电钻拧松钻夹头。
随着自锁结构的广泛应用， 由于内锥钻夹头所存在的上述缺陷， 而内锥钻夹 头的优点所对应的功能， 自锁结构也能实现， 因此， 内锥钻夹头已没有存在的基 础，被逐渐被打入冷宫被人遗忘，时至今日，具有自锁结构的钻夹头盛行于市场， 而内锥钻夹头几乎看不到有批量产品出现。
一切似乎已被定论，对于机床用的钻夹头由自紧钻夹头担当， 对于电钻用的 钻夹头， 由手紧钻夹头和扳手钻夹头担当，如需进一步提高性能，增加自锁结构。
但随着相关产业的不断发展， 无绳电钻也即由蓄电池供电的电钻进一步流 行， 而且， 随着技术的进步， 无论蓄电池容量和电钻电机功率都提高很快， 但是 手紧钻夹头乃至扳手钻夹头的夹持力却成为了瓶颈，难以充分发挥电钻电机的功 率， 制约了手枪电钻的进一步发展。 发明内容
本实用新型所要解决的技术问题是提供一种防抱死的内锥钻夹头，为充分利 用目前高功率的手枪电钻电机的效能，促进手枪电钻的进步，提供一种解决方案。 为此， 本实用新型采用以下技术方案： 设有与驱动机器配合连接的连接体， 连接 体的后部设有用于与驱动机器连接的连接孔，所述连接体的前端为锥形头并在锥 形头上设置有外螺纹，所述钻夹头还设有可相对连接体转动的钻体， 所述钻体套 在连接体外，钻体中设有围绕连接孔轴线分布的夹爪孔， 所述钻夹头的夹爪穿过 所述夹爪孔与所述外螺纹螺纹连接，所述螺纹连接的螺纹为反向螺纹， 所述连接 体自其前端向后开设有与所述连接孔同轴的前部孔段，所述前部孔段侵入或穿过 所述外螺纹所在的连接体区段，所述连接体自其前端向后开有贯穿前部孔段孔壁 的槽， 所述槽的深度到达所述外螺纹中或向后一直透过所述外螺纹。
进一步地， 本实用新型具有 1个或多个所述槽。
进一步地， 当本实用新型具有多个所述槽时， 所述多个槽沿前部孔段的周向 均匀分布， 所述多个槽的深度一致。
本实用新型还可设有与连接体同轴的旋转套， 所述旋转套处在旋转体之外， 旋转套和连接体之间设有自锁结构，所述自锁结构包括设置在连接体上的一圈棘 齿、 处在连接体和旋转套之间的弹簧片、旋转套上的控制弹簧片工作的凸轮， 所 述钻体上具有转位槽，所述旋转套上被配有与转位槽配合的键使得旋转套在正反 两个方向上能带动钻体旋转；旋转套内表面还设有分别对应自锁状态和非自锁状 态的定位凹槽， 弹簧片具有与棘齿配合的锁端、与定位凹槽配合的凸起、 与凸轮 面配合的凸起。
所述钻体连接与其同步转动的内套， 所述弹簧片的所述凸起卡在内套上 由于采用本实用新型的技术方案， 本实用新型为内锥钻夹头赋予了新的理 念， 反其道行之， 采用简单的容易实现的技术手段使内锥钻夹头具有适度的弹性 平衡功能。在工作中钻夹头由于载荷变化和惯性的连续作用， 夹持钻具的力越来 越大， 过度自紧时， 所述连接体前部孔段的槽使连接体上的外螺纹所在区域的孔 壁在反作用力的作用下具有微小的弹性变形性能，使前部孔段的孔壁向连接体中 心方向有微小变形， 这样螺纹接触面就比正常要小， 接触面小其相互之间摩擦力 小， 从而防止了抱死现象的出现， 使内锥钻夹头松开钻具的操作比较轻松。 从而 使钻夹头既具有较高的夹持力， 防止受到冲击时松动， 又使内锥钻夹头松开钻具 的操作比较容易， 在应用于高功率的手枪电钻时， 能够充分发挥其作用， 从而使 本已退出舞台的内锥钻夹头起死回生，反而成为手枪电钻适应新技术进步的一个 行之有效、 行至较易的解决方案。 附图说明
