下面结合附图给出本发明较佳实施例, 以详细说明本发明的技术方案。 如图 1 所示, 本实施例中的该无绳磁座钻包括: 控制单元 1 , 该控制单 元 1为该无绳磁座钻的中枢控制模块, 用于根据操作者的控制指令对该无绳 磁座钻中的各个必备模块以及各个可选模块进行统一控制; 与该控制单元 1 相连的电机 2 , 该电机 2被作为该无绳磁座钻上装配的各类钻削工具的旋转 驱动模块; 与该电机 2相连的变速箱 3 , 该变速箱 3用于将该电机 2的输出 转速调节至实际作业所需的合适转速, 以使得钻削工具能够以该合适转速对 工件进行理想的钻削加工; 与该控制单元 1相连的动力源 4 , 该动力源 4为 便携式无绳动力源, 其可以向该电机 2提供动力, 但该动力源 4与该电机 2 之间是否建立实际联接则将受到该控制单元 1 的控制, 下文中将对该控制方 式进行详细描述; 磁座 5 , 该磁座 5通过其磁场将该无绳磁座钻可靠地吸附 于作业面上, 该磁座 5可以选用电磁吸盘、 电永磁吸盘、 永磁吸盘或永磁吸 盘与电磁吸盘的结合, 在选用电磁吸盘及电永磁吸盘的情况下, 该磁座 5将 与该控制单元 1相连, 在选用永磁吸盘的情况下, 该磁座 5将不与该控制单 元 1相连, 在选用永磁吸盘与电磁吸盘的结合的情况下, 该磁座 5中的永磁 吸盘不与该控制单元 1相连而电磁吸盘则将与该控制单元 1相连, 以下将通 过各个实施例对上述不同情况进行详细说明。 其中, 该控制单元 1也可以具 有人机交互界面, 例如: 几个简单的供操作者对该无绳磁座钻进行控制的开 关, 以及几个简单的反映该无绳磁座钻的运行状态的指示灯; 或者, 该人机 交互界面也可以为较为复杂的控制面板, 该控制面板甚至可以具有显示屏, 以实时地对该无绳磁座钻的运行状态进行显示, 以供操作者进行监控, 而操 作者也可以通过该控制面板向该控制单元 1输入控制指令, 以对该无绳磁座 钻的运行进行控制, 特别地, 该控制单元 1还可以具有 ^警功能, 以在该无 绳磁座钻工作异常时通过该人机交互界面向操作者及时地发送警告提示。
实施例 1 如图 1所示, 在该实施例中, 该磁座 5釆用电磁吸盘 5a , 并且利用该动 力源 4向该电磁吸盘 5a提供产生磁场的动力。在该无绳磁座钻预备开始进行 作业以及作业结束时, 由该控制单元 1分别建立以及切断该动力源 4与该电 磁吸盘 5 a之间的联接, 以产生或消除该电磁吸盘 5 a的磁场, 而在该无绳磁 座钻的使用过程中, 该动力源 4则持续地与该电磁吸盘 5a保持联接, 从而保 证该无绳磁座钻的吸附可靠性。
当该动力源 4的能量即将耗尽时,为了防止由于该电磁吸盘 5a突然断电 失去吸附力而导致该无绳磁座钻从作业面上滑脱甚至坠落, 该控制单元 1可 以在该电机 2彻底耗尽该动力源 4的动力之前, 提前切断该动力源 4与该电 机 1之间的联接,使得该电磁吸盘 5a仍然能够依靠该动力源 4的剩余动力继 续运行, 甚至还可以降低该电磁吸盘 5a的工作电压, 只要其吸附力足以将该 无绳磁座钻维持在作业面上即可, 从而减少该电磁吸盘 5a的能耗, 使其磁场 维持更长的时间。 或者, 该控制单元 1也可以通过该人机交互界面发出警告, 以提示操作者该动力源 4的能量已经不足, 以便操作者及时地将该无绳磁座 钻移至不会发生坠落的安全位置, 并将该动力源 4更换或重新充满。 又或者, 该控制单元 1也可以在切断该动力源 4与该电机 1之间的联接的同时通过该 人机交互界面发出警告。
在该实施例中, 该便携式无绳动力源 4可以釆用三元锂电池、 磷酸铁锂 电池等各种锂基电池; 燃料电池; 镍镉电池、 镍氢电池、 镍辞电池等各种化 学电池; 以及其它各种移动动力源。 对于某些种类的动力源, 出于安全或寿 命等原因, 需要对其进行过载保护、 低压保护、 过热保护等多种保护措施, 因此, 当本发明的该动力源 4釆用了需要保护的动力源时, 可以根据需要为 该动力源 4加装动力源控制器或动力源传感器(图中未示), 以下将针对分别 加装这两种模块的情况进行说明。
当釆用动力源控制器时, 该动力源控制器可以根据该动力源 4的运行状 态自动地对该动力源 4做出保护动作, 由于该保护动作可能会突然造成对该 动力源 4的全部动力输出的切断,而这将使得该电磁吸盘 5a断电而失去吸附 力, 进而导致该无绳磁座钻从作业面上滑脱或坠落, 出于对使用安全的考虑, 在设置了动力源控制器的情况下, 该控制单元 1必须能够在该动力源控制器 切断该动力源 4的全部动力输出之前, 先行对该动力源 4的异常状况做出反 应, 例如: 切断该动力源 4与该电机 2之间的联接, 以防止该动力源 4达到 该动力源控制器的保护阔值而被切断全部的动力输出, 从而保留足够的动力 使得该电磁吸盘 5a仍然能够继续地吸附于作业面上,给操作者提供充分的处 理时间, 甚至还可能因为切断了该动力源 4与该电机 1之间的联接, 从而降 低了该动力源 4的负载, 而直接消除了该动力源 4的异常状况; 或者, 该控 制单元 1也可以通过人机交互界面发出警告, 以提示操作人员及时地对该动 力源 4的异常状况进行处理; 又或者, 该控制单元 1也可以在切断该动力源 4与该电机 1之间的联接的同时发出警告。 具体地例如: 当通过该动力源控 制器对该动力源 4进行过载保护时, 该控制单元中需要相应地设计有过载保 护模块, 并且, 该过载保护模块的预设过载保护电流阔值应当低于该动力源 控制器的预设过载保护电流阔值, 并且该过载保护模块对过载现象做出保护 动作的反应时间也应当小于该动力源控制器的反应时间, 由此, 当该动力源
4发生过载时, 该控制单元 1会在该动力源控制器做出保护动作之前, 切断 该动力源 4与该电机 2之间的联接, 和 /或, 通过该人机交互界面向操作者发 送过载警告; 当通过该动力源控制器对该动力源 4进行低压保护时, 该控制 单元中需要相应地设计有低压保护模块, 并且, 该低压保护模块的预设低压 保护电压阔值应当高于该动力源控制器的预设低压保护电压阔值, 并且该低 压保护模块对低压现象做出保护动作的反应时间也应当小于该动力源控制器 的反应时间, 由此, 当该动力源 4电压过低时, 该控制单元 1会在该动力源 控制器做出保护动作之前, 切断该动力源 4与该电机 2之间的联接, 和 /或, 通过该人机交互界面向操作者发送低压警告; 当通过该动力源控制器对该动 力源 4进行过热保护时, 该控制单元中需要相应地设计有过热保护模块, 并 且, 该过热保护模块的预设过热保护温度阔值应当低于该动力源控制器的预 设过热保护温度阔值, 并且该过热保护模块对过热现象做出保护动作的反应 时间也应当小于该动力源控制器的反应时间, 由此, 当该动力源 4发生过热 时, 该控制单元 1会在该动力源控制器做出保护动作之前, 切断该动力源 4 与该电机 2之间的联接,和 /或,通过该人机交互界面向操作者发送过热警告。
当釆用动力源传感器时, 该动力源传感器与该动力源 4以及该控制单元 1 均相连, 其可以探测获取该动力源 4 的运行状态, 并将该运行状态数据传 输给该控制单元 1进行处理, 而该控制单元 1则可以对该运行状态数据进行 判断, 在该动力源 4发生诸如过载、 低压、 过热等各种异常状况时, 及时地 切断该动力源 4与该电机 2之间的联接, 以起到对该动力源 4的保护作用, 和 /或, 该控制单元 1也可以通过该人机交互界面向操作者发送警告; 在执行 上述保护动作时, 该电磁吸盘 5a仍然能够维持在作业面上的吸附, 从而给操 作者提供充分的处理时间, 以免因该无绳磁座钻的突然滑脱或坠落而发生安 全事故。 另外, 要加以说明的是, 即使在釆用了动力源控制器而非动力源传 感器的情况下, 该动力源控制器也可以执行与该动力源传感器相同的功能, 即探测获取该动力源 4的运行状态, 并由该控制单元 1对该运行状态数据进 行与上述内容相同的后续处理。
为了更进一步地提高该无绳磁座钻的使用安全性, 其还可以增设与该控 制单元 1相连的备用动力源 6 , 该备用动力源 6用于在该动力源 4无法正常 地向该电磁吸盘 5a提供动力时, 继续为该电磁吸盘 5a提供动力。 该控制单 元 1 可以控制该动力源 4为该备用动力源 6补充动力, 并在该备用动力源 6 已经充满时, 切断该动力源 4与该备用动力源 6之间的联接; 或者, 也可以 通过外接动力源为该备用动力源 6补充动力, 从而确保该备用动力源 6能够 时刻处于充满状态, 以备不时之需。 当该动力源 4能量耗尽, 或者是出现工 作异常, 例如发生过载、 低压、 过热、 电气联接不良等现象, 或者是被上述 的动力源控制器切断了全部的动力输出,从而可能会对该电磁吸盘 5a的正常 吸附产生影响时,该控制单元会控制该备用动力源 6向该电磁吸盘 5a提供动 力, 例如: 主动地切断该动力源 4与该电磁吸盘 5a的联接, 同时建立该备用 动力源 6与该电磁吸盘 5 a的联接, 以保证该电磁吸盘 5 a的正常运行; 与此 同时, 该控制单元 1同样可以通过切断该动力源 4与该电机 2之间的联接以 对该动力源 4实施保护; 和 /或, 通过该人机交互界面向操作者发送警告。 该 备用动力源 6可以釆用以下的动力源类型, 即: 三元锂电池、 磷酸铁锂电池 等各种锂基电池; 燃料电池; 镍镉电池、 镍氢电池、 镍辞电池等各种化学电 池; 以及其它各种移动动力源。
在该无绳磁座钻的使用中, 有时会因为作业面不清洁, 例如存在沙尘或 异物等等, 导致该电磁吸盘 5a无法与作业面良好吸附, 使得该无绳磁座钻有 滑脱或坠落的危险, 为了避免发生此状况, 还可以在该无绳磁座钻中加装磁 场传感器 7 , 该磁场传感器 7与该控制单元 1相连, 用于探测获取该电磁吸 盘 5a的运行状态, 并将该运行状态数据传输给该控制单元 1进行处理, 而该 控制单元 1则会根据该运行状态数据, 判断该电磁吸盘 5a的磁场是否正常, 即该无绳磁座钻是否与作业面处于良好的吸附状态。 例如, 在启动该无绳磁 座钻时,若该磁场传感器 7探测到该电磁吸盘 5a的磁场不足以维持其与作业 面之间的良好吸附, 则该控制单元 1将会阻止该动力源 4与该电机 2之间建 立联接, 从而确保该无绳磁座钻仅有在已经与作业面处于良好吸附的状态下 才能够开始进行钻削作业; 而在该无绳磁座钻的使用过程中, 当该磁场传感 器 7探测到该电磁吸盘 5a的磁场不足时,该控制单元 1也将及时地切断该动 力源 4与该电机 1之间的联接, 以防该电磁吸盘 5a从作业面上滑脱之后, 导 致产生整个无绳磁座钻绕该钻削工具旋转的危险, 和 /或, 通过该人机交互界 面向操作者发送警告。
为了更进一步地确保该无绳磁座钻在作业面上的可靠固定, 其还可以包 括机械安全装置, 该机械安全装置可以为例如链、 绳、 钳等形式, 以防止该 无绳磁座钻发生意外的滑脱或坠落。
实施例 2
该实施例中的该无绳磁座钻的结构与实施例 1非常类似, 以下将仅对它 们之间的不同之处进行说明。 如图 3所示, 在该实施例中, 该磁座 5釆用电 永磁吸盘 5b , 该电永磁吸盘 5b在正常运行时无需该动力源 4为其提供动力, 而仅在开启以及关闭时需要由该控制单元 1向其发出开 /关电信号, 例如, 操 作者可以通过该人机交互界面向该控制单元 1输入对该电永磁吸盘 5b的开关 指令, 而后由该控制单元 1根据接收到的指令, 开启或者关闭该电永磁吸盘 5b的磁场。
由于该电永磁吸盘 5b 是无需任何动力便可以永久性地产生磁场的, 因 此, 在该实施例中, 无论该动力源 4的运行状态发生任何异常, 例如能量即 将耗尽, 或发生过载、 低压、 过热等现象时, 均不会对该电永磁吸盘 5b的正 常吸附产生影响, 因此可以充分地确保该无绳磁座钻的使用安全。 相应地, 在例如该动力源 4的能量即将耗尽时, 便无需再提前切断该动力源 4与该电 机 2之间的联接以为该电永磁吸盘 5b的正常吸附保留动力;在釆用了实施例 1 中所述的动力源控制器时, 也无需再将该控制单元设计为在该动力源控制 器动作之前对该动力源 4的异常状况做出反应; 也无需再设置实施例 1中所 述的该备用动力源 6 ; 当釆用了实施例 1 中所述的该磁场传感器 7时, 该磁 场传感器 7则相应地用于探测该电永磁吸盘 5b的磁场状态。
该实施例中的其余模块及相应模块的工作方法均与实施例 1相同。
实施例 3 该实施例中的该无绳磁座钻的结构与实施例 2非常类似, 以下将仅对它 们之间的不同之处进行说明。 如图 4所示, 在该实施例中, 该磁座 5釆用永 磁吸盘 5c , 该永磁吸盘 5c无需该动力源 4为其提供动力, 也无需受到该控 制单元 1 的控制, 便可以自发地持续地产生磁场, 从而将该无绳磁座钻可靠 地吸附于作业面上。 在该无绳磁座钻预备开始进行作业以及作业结束时, 该 永磁吸盘 5c 与作业面之间的吸附以及释放动作可以通过业内熟知的直接设 于该永磁吸盘 5c上的简单机械结构实现, 在此不做赘述, 也可以将对上述吸 附与释放动作的机械控制后台集成在该人机交互界面上, 从而操作者可以直 接在该人机交互界面上进行对该永磁吸盘 5c的吸附与释放动作的控制。
由于该永磁吸盘 5c 也是无需任何动力便可以持续性地产生磁场的, 因 此, 与实施例 2相比, 除了在釆用上述的磁场传感器 7时其探测对象将变为 该永磁吸盘 5c以外,该实施例中的其余模块及相应模块的工作方法均与实施 例 2相同。
实施例 4
该实施例中的该无绳磁座钻的结构与实施例 1非常类似, 以下将仅对它 们之间的不同之处进行说明。 如图 5所示, 在该实施例中, 在釆用了实施例 1中所述的该电磁吸盘 5a的基础上还增设了吸附力相对较小的永磁吸盘 5d , 该电磁吸盘 5a与该永磁吸盘 5d共同作为该无绳磁座钻的该磁座 5。 该永磁 吸盘 5d的吸附力应当被选择为: 当该电磁吸盘 5a因为断电而完全失去磁场 时,该永磁吸盘 5d仍然能够保证该无绳磁座钻可靠地吸附于作业面上。此处, 对该电磁吸盘 5a的控制方式与实施例 1中所述相同, 而对该永磁吸盘 5d的 控制方式则与实施例 3中所述的对永磁吸盘 5c的控制方式相同。
由于该永磁吸盘 5d是无需任何动力便可以永久性地产生磁场的, 因此, 在该实施例中, 与实施例 2的情况类似地, 无论该动力源 4的运行状态发生 任何异常, 例如能量即将耗尽, 或发生过载、 低压、 过热等现象时, 均不会 对该永磁吸盘 5d的正常吸附产生影响, 因此可以充分地确保该无绳磁座钻的 使用安全。 相应地, 在例如该动力源 4的能量即将耗尽时, 无需再提前切断 该动力源 4与该电机 1之间的联接以为该永磁吸盘 5d的正常吸附保留动力; 在釆用了实施例 1 中所述的动力源控制器时, 也无需再将该控制单元设计为 在该动力源控制器动作之前对该动力源 4的异常状态做出反应; 也无需再设 置实施例 1 中所述的该备用动力源 6 ; 当釆用了实施例 1 中所述的该磁场传 感器 7时, 该磁场传感器 7则相应地用于探测该电磁吸盘 5a与该永磁吸盘 5d的叠加磁场^ 态。
该实施例中的其余模块及相应模块的工作方法均与实施例 1相同。
本发明中所述的该控制单元 1除了可以实现上述的多种控制功能以外, 还可以对其增加诸如下述的各种辅助功能: 对该电机 2进行过载保护, 在该 人机交互界面上向操作者提供对该电机 2的转速进行人为调节的功能, 对该 无绳磁座钻的任意模块进行过热保护, 实现无需任何手动操作的自动钻削作 业, 对该无绳磁座钻的工作照明进行控制等等, 而所述的所有功能均可以利 用现有的硬件条件结合现有的编程手段加以实现,在此其实现方法不做赞述。
