技术领域
本申请涉及电动工具技术领域，特别是涉及一种打钉设备。
背景技术
在许多工程建设、房屋建筑、室内外装修、家具制造、展会布置等领域中，都需要采用钉枪把需要固定的部件固定在基材上。目前，用的最多的是以压缩空气为动力源的气动钉枪。但是，气动钉枪的动力源——气泵是一个较为笨重的装置，移动携带不方便。因此以电为动力源的钉枪就应运而生了。而市面上的电动钉枪，以市电为电源的主要是电磁线圈驱动的电钉枪。电磁线圈驱动的钉枪不仅还需要拖一根电线，造成使用不方便；而且电磁线圈的驱动力明显不足，不能满足工程实际的需要。从发展趋势看已经逐渐被电池驱动的所谓无绳钉枪所取代。
目前，无绳钉枪的主要工作方式是用电机驱动蓄能机构，蓄能后快速释放打钉。蓄能的方式有：飞轮机构、弹簧机构、压缩气体机构(压缩气体机构又可分为常压方式和预压缩方式(高压方式))。这些方式在打击能量小于30焦耳的钉枪中都有很好的应用。但是，飞轮机构复杂，能量明显有极限，再提高很难；弹簧机构直接驱动打钉，效果很差；压缩气体机构特别是预压缩高压机构打钉效果较好，有领先其他两种蓄能驱动机构的趋势，但是这类机构的密封总是问题，密封寿命是这类机构的软肋。因此，目前的电动钉枪存在的主要问题是摩擦损耗大、能量不足、能效不高、打钉效果差，影响使用。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本 申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例一
本申请一实施例提供了一种打钉设备，该打钉设备能够将固定元件钉在基材上，进而使固定元件将需要固定的部件固定在基材上。在本实施例中，固定元件主要是指钉子，当然，在本申请的其他实施方式中，固定元件还可为其他与钉子相类似的固定件。本申请提供的打钉设备在获得较大打钉力的同时其结构仍然保持紧凑，具有较高的能效，提高打钉效果。
如图1至图4所示，本申请实施例一提供一种打钉设备，包括：支撑结构100、蓄能机构200，蓄能驱动机构300和传动打钉机构400，蓄能机构200设置于支撑结构100中，蓄能机构200能够储存或释放能量，蓄能驱动机构300设置于支撑结构100中，用于驱动蓄能机构200存储能量；蓄能驱动机构300包括动力部件310、与动力部件310连接的偏心部件320、与偏心部件320连接的直线运动部件330、单向锁止结构340及位置传感器，单向锁止结构340设置于偏心部件320和支撑结构100之间，单向锁止结构340限制偏心部件320沿单一方向转动，位置传感器能够检测偏心部件320的转动位置，动力部件310包括驱动电机311及安装于驱动电机311的输出轴上的减速器312，位置传感器与驱动电机311电连接，蓄能机构200驱动传动打钉机构400撞击钉子，以将钉子打入基材。蓄能时，动力部件310驱动偏心部件320转动，带动直线运动部件330做直线运动，使蓄能机构200储存能量。当蓄能机构200接近最大储存能量时，此时偏心部件320处于接近上死点位置，如图9所示。位置传感器检测到偏心部件320接近上死点位置时，即偏心部件320被驱动到上死点前0°-20°时，驱动电机311停止工作，单向锁止结构340对偏心部件320进行反向转动锁止；接到打钉指令时，驱动电机311带动偏心部件320转动，极短时间内通过上死点位置，蓄能机构200释放能量，驱动传动打钉机构400撞击钉子，以将钉子打入基材。位置传感器、单向锁止结构340以及电机的配合，实现了打钉设备的提前蓄能、快速打钉，节省了打钉等待时间，提高了打钉设备的工作效率。
减速器312设置在驱动电机311的输出轴上，偏心部件320与减速器312的输出端连接，并抵接在直线运动部件330上，驱动电机311输出的运动通过减速器312减速后再传递到偏心部件320上，这样能够增加扭矩，提高对蓄能机构200的储能驱动力。可选地，减速器312为行星减速器。本申请的打钉设备可以与交流电源连接，实现打钉设备的驱动；当然，本申请的打钉设备也可通过蓄电池来提供电能。
在其中一个实施例中，如图3及图4所示，直线运动部件330包括挺柱，挺柱的一端与偏心部件320抵接，挺柱的另一端与蓄能机构200连接。当然，在本申请的其他实施例中，直线运动部件330还可以为其他能够实现直线运动的结构。使用挺柱作为直线运动部件330，具有结构简单、稳定性强、互换性高的特点。
在其中一个实施例中，如图3所示，蓄能机构200包括蓄能弹簧，支撑结构100上具有安装空腔，蓄能弹簧安装于支撑结构100的安装空腔中。挺柱可以驱动蓄能弹簧，使蓄能弹簧储存能量；蓄能弹簧释放能量时，蓄能弹簧使挺柱反向运动。蓄能弹簧是用来实现 能量的存储与释放的。蓄能弹簧的轴线方向与挺柱的运动方向平行，避免蓄能时蓄能弹簧发生偏斜。蓄能弹簧的一端与支撑结构100连接，另一端与挺柱连接。进一步，蓄能弹簧为压缩弹簧或气体弹簧。压缩弹簧或气体弹簧设置于支撑结构100中，压缩弹簧或气体弹簧的一端与支撑结构100连接，另一端与挺柱连接。
如图4所示，在其中一个实施例中，传动打钉机构400包括杠杆传动部件及用于打钉的击钉部件420，杠杆传动部件的一端可转动地固定在支撑结构100上，杠杆传动部件具有中间支点，杠杆传动部件在中间支点处与直线运动部件330连接，杠杆传动部件的另一端与击钉部件420传动连接，直线运动部件330带动杠杆传动部件运动，使杠杆传动部件驱动击钉部件420撞击钉子。
如图2和图3所示，在另一个实施例中，传动打钉机构400包括液压传动部件410以及用于打钉的击钉部件420，支撑结构100中开设有连通腔110作为液压传动部件410的连通通路。
如图3及图5所示，作为一种可选择的实施方式，偏心部件320包括偏心轴321及套设于偏心轴321上的轴承。偏心轴321与动力部件310传动连接，轴承与直线运动部件330抵接，动力部件310驱动偏心轴321带动轴承转动，轴承带动直线运动部件330做直线运动。较佳地，轴承为滚动轴承，以减少运动传递的摩擦损耗，使得直线运动部件330做无侧向摩擦力直线运动，保证很高的蓄能能效。蓄能时，偏心轴321的偏心运动能够带动轴承做偏心转动，带动直线运动部件330做直线运动，驱动压缩蓄能机构200存储能量；蓄能机构200释放能量时，推动直线运动部件330做直线运动，并通过传动打钉机构400撞击钉子。
本实施例的打钉设备通过偏心轴321与滚动轴承322配合，实现了对直线运动部件330无侧向摩擦的直线驱动，极大的消除了侧向力产生的摩擦损耗，进而实现高效驱动蓄能机构200储存能量，提高了整个打钉设备的能效，减小了驱动力，使得整体尺寸减小，重量减轻，更加便于携带。对于使用蓄电池作为能源的打钉设备而言，减小摩擦损耗意味着大大的提高蓄电池单次充电的打钉数目，提高工作效率，提高了蓄电池的利用率。
当然，在本申请的其他实施方式中，偏心部件320包括转轴及套设于转轴上的偏心轴承。转轴与动力部件310传动连接，偏心轴承与直线运动部件330抵接，动力部件310驱动转轴带动偏心轴承转动，偏心轴承带动直线运动部件330做直线运动。蓄能时，直线运动部件330驱动蓄能机构200存储能量；蓄能机构200释放能量时，驱动直线运动部件330做直线运动，并通过传动打钉机构400撞击钉子。
在其中一个实施例中，如图3及图6所示，单向锁止结构340设置于支撑结构100与偏心部件320之间，可选的，单向锁止结构340可以是棘轮棘爪结构，也可以是其他能够实现单向锁止功能的结构，进一步，单向锁止结构340包括单向轴承，偏心部件320的一端或两端通过单向轴承转动设置于支撑结构100，单向轴承具有结构简单、互换性强、性能稳定、易于拆装的优点。
可选的，位置传感器可以是各种可探测偏心轴位置信息的光电传感器、角位移传感器或接近开关等，位置传感器也可以是其他能够检测偏心部件320转动位置的传感器。位置 传感器与驱动电机311电连接，当偏心部件320被驱动接近上死点位置时，位置传感器发出信号，控制驱动电机311停止工作。在一个具体的实施例中，位置传感器是光电式角位移传感器，当偏心轴321转动至接近最大蓄能状态的上死点位置时，光电式角位移传感器传出信号，驱动电机311停止转动。接到打钉指令时，驱动电机311带动偏心轴321越过上死点位置，打钉结束后，打钉设备自动进入下一个蓄能过程，驱动电机311带动偏心轴321转动蓄能，当位置传感器检测到偏心部件320处于上死点位置之前0°-20°时，驱动电机311停止工作，单向锁止结构340对偏心部件320进行反向锁止，使得偏心部件320既不会在蓄能机构200的驱动下反转，也不会越过上死点位置误打钉，打钉设备处于准备打钉状态。打钉设备在接收到下一个打钉指令时，偏心部件320只需再被驱动0°-20°，就可以实现打钉动作，大大缩短了打钉等待时间，保证了打钉效率。进一步，当位置传感器检测到偏心部件320处于上死点位置之前5°-10°时，驱动电机311停止工作，单向锁止结构340对偏心部件320进行反向锁止，使得偏心部件320既不会在蓄能机构200的驱动下反转，也不会越过上死点位置误打钉，打钉设备处于准备打钉状态。打钉设备在接收到下一个打钉指令信号时，偏心部件320只需再被驱动5°-10°，就可以实现打钉动作，大大缩短了打钉等待时间，保证了打钉效率。
如图6和图7所示，在其中一个实施例中，蓄能驱动机构300还包括单向离合器部件350，单向离合器部件350安装在动力部件310的输出轴与偏心部件320之间。如图8及图11所示，蓄能机构200储存能量时，单向离合器部件350处于连接位置，动力部件310通过单向离合器部件350驱动偏心部件320转动，偏心部件320驱动直线运动部件330做直线运动，以驱动蓄能机构200蓄能。蓄能机构200释放能量时，如图9及图10所示，单向离合器部件350处于分离位置，蓄能机构200驱动直线运动部件330做直线运动，并通过传动打钉机构400撞击钉子，以将钉子打入基材。单向离合器部件350的作用在于使蓄能机构200在打钉时能够迅速释放能量，提高打钉时机构的运动速度，保证打钉效果。
单向离合器部件350在动力部件310驱动偏心轴321转动蓄能时，总是处于连接位置。当偏心轴321在蓄能机构的驱动下，转速超过动力部件310的输出轴转速时，单向离合器部件350总是处于分离位置。单向离合器部件350驱动偏心轴321转动时，偏心轴321驱动直线运动部件330使蓄能机构200储存能量，这时单向离合器部件350处在连接位置，驱动电机311通过单向离合器部件350与偏心轴321传动连接，此时，驱动电机311的动力通过单向离合器部件350传递到偏心轴321上，以驱动偏心轴321运动。蓄能机构200释放能量时，如图9及图10所示，蓄能机构驱动直线运动部件330运动，直线运动部件330推动偏心轴321转动，偏心轴321的转速超过动力部件310的输出轴转速，单向离合器部件350处于分离位置。这样偏心轴321能够在直线运动部件330的驱动下自由快速旋转，只消耗很少的能量，使得蓄能机构200上蓄积的大部分能量迅速通过传动打钉机构400撞击钉子，将钉子打入基材。如图11所示，当蓄能机构200释放能量完毕，单向离合器350重新进入接触状态并进行下一次蓄能的过程。
本申请的打钉设备通过单向离合器部件350实现了驱动电机311动力的单向传递，保证了驱动电机311的驱动力能够驱动偏心轴321带动直线运动部件330向蓄能机构200储 存能量，同时又能保证打钉时蓄能机构200上的能量迅速释放，保证打钉效果。作为一种可实现的方式，如图5至图7所示，单向离合器部件350包括装设在偏心部件320上的驱动销351、连接轴352和驱动盘353。驱动盘353与减速器312的输出轴传动连接，连接轴352与驱动盘353转动连接且有大于90°的转角间隙，驱动销351与连接轴352转动连接且有大于90°的转角间隙。蓄能机构200蓄能时，驱动盘353与连接轴352、连接轴352与驱动销351均处于驱动接触状态。动力部件310通过驱动盘353、连接轴352及驱动销351接触并驱动偏心部件320转动，偏心部件320驱动直线运动部件330运动，以驱动蓄能机构200蓄能。蓄能机构200释放能量时，驱动销351的转速大于连接轴352的转速，驱动销351与连接轴352分离，同理，连接轴352与驱动盘353分离，蓄能机构200驱动传动打钉机构400撞击钉子，以将钉子打入基材。
进一步，驱动销351的数量是两个，两个驱动销351设置在偏心轴321靠近减速器312的一端的端面上，两个驱动销351的连线穿过偏心轴321的转动中心。连接轴352的两侧分别设置有传动拨块3521，两个传动拨块3521沿偏心轴321的转动方向相对固定。驱动盘353的中心具有传动通孔，传动通孔的侧壁上设置有两个传动突起3531，两个传动突起3531的连线穿过驱动盘353的转动中心。蓄能机构200蓄能时，减速器312的输出端带动驱动盘353转动，驱动盘353的两个传动突起3531与连接轴352一侧的传动拨块3521接触，进而驱动盘353驱动连接轴352转动。连接轴352另一侧的传动拨块3521与两个驱动销351接触，进而连接轴352驱动偏心轴321转动。偏心轴321驱动直线运动部件330运动，进而驱动蓄能机构200蓄能。蓄能机构200释放能量时，直线运动部件330驱动偏心轴321快速转动。驱动销351的转速大于连接轴352的转速，驱动销351与连接轴352分离。当驱动销351反向与连接轴352一侧的传动拨块3521接触并带动连接轴352转动时，连接轴352的转速大于驱动盘353的转速。连接轴352另一侧的传动拨块3521与驱动盘353的传动突起3531分离。蓄能机构200在释放能量过程中，只带动偏心部件320转动，使得蓄能机构200上蓄积的大部分能量迅速通过传动打钉机构400撞击钉子，将钉子打入基材。在其他的实施例中，单向离合器部件350还可以是楔块式单向离合器、滚柱式单向离合器、棘轮式单向离合器或者其他类型的单向离合器。

当然，在本申请的其他实施方式中，偏心部件320包括转轴及套设于转轴上的偏心轴承。转轴与动力部件310传动连接，偏心轴承与直线运动部件330抵接，动力部件310驱动转轴带动偏心轴承转动，偏心轴承带动直线运动部件330做直线运动。蓄能时，直线运 动部件330驱动蓄能机构200存储能量；蓄能机构200释放能量时，驱动直线运动部件330做直线运动，并通过液压传动部件410带动击钉部件420撞击钉子。
本实施例的打钉设备通过偏心轴与滚动轴承配合，实现了对直线运动部件330无侧向摩擦的直线驱动，极大的消除了侧向力产生的摩擦损耗，进而实现高效驱动蓄能机构200储存能量，提高了整个打钉设备的能效，减小了驱动力，使得整体尺寸减小，重量减轻，更加便于携带。对于使用蓄电池作为能源的打钉设备而言，减小摩擦损耗意味着大大的提高蓄电池单次充电的打钉数目，提高工作效率，提高了蓄电池的利用率。
在其中一个实施例中，支撑结构中开设有连通腔110，液压传动部件410包括由连通腔110相互连通的第一缸体411和第二缸体413，连通腔110及第一缸体411和第二缸体413均固定设置于支撑结构，连通腔110及第一缸体411和第二缸体413之间封闭有液体，第一缸体411内设置有第一活塞412，第一活塞412与第一缸体411的内壁动配合，击钉部件420远离钉子的一端设置有第二活塞414，第二活塞414与第二缸体413的内壁动配合。蓄能机构200与击钉部件420通过相互连通的不同内径的缸体连通，通过使用不同内径的缸体，能够轻松地实现蓄能机构200与击钉部件420之间不同的传动比。蓄能过程中，在直线运动部件330的推动下，第一活塞412沿第一缸体411轴向向连通腔110外方向运动，压缩蓄能机构200中的气体弹簧(或机械弹簧)蓄能，液体流向第一缸体411内；第二活塞414在负压和回程弹簧(图上没有标出)的作用下沿第二缸体413的轴向向连通腔110内方向运动。释放能量时，蓄能机构200推动第一活塞412沿第一缸体411的轴向向连通腔110内方向运动，挤压液体，受挤压的液体驱动第二缸体413中的第二活塞414沿轴向向连通腔110外方向运动，带动击钉部件420做直线运动，将钉子打入基材。在其中一个实施例中，直线运动部件330包括挺柱，挺柱的一端与偏心部件320抵接，挺柱的另一端与蓄能机构200连接。
在其中一个实施例中，如图15所示，蓄能机构200包括蓄能弹簧，支撑结构上具有安装空腔，蓄能弹簧安装于支撑结构的安装空腔中。挺柱可以驱动压缩蓄能弹簧，使蓄能弹簧储存能量；蓄能弹簧释放能量时，蓄能弹簧使挺柱反向运动。蓄能弹簧是用来实现能量的存储与释放的。蓄能弹簧的轴线方向与挺柱的运动方向平行，避免蓄能时蓄能弹簧发生偏斜。蓄能弹簧的一端与安装空腔的顶壁相接触，另一端与第一活塞412的一侧相抵接，第一活塞412的另一侧与挺柱相连接。进一步，蓄能弹簧为压缩弹簧(图15)或气体弹簧(图13、图14)。压缩弹簧或气体弹簧设置于支撑结构中，压缩弹簧或气体弹簧的一端与支撑结构抵接，压缩弹簧或气体弹簧的另一端与第一活塞412相连接，第一活塞412的另一端与挺柱连接。如图13、图14所示，在另一个实施例中，蓄能机构200通过对封闭气体的压缩和释放完成蓄能以及能量释放的过程。
在其中一个实施例中，蓄能驱动机构300还包括单向离合器部件340，单向离合器部件340安装在动力部件310的输出轴与偏心部件320之间。蓄能机构200储存能量时，单向离合器部件340处于连接位置，动力部件310通过单向离合器部件340驱动偏心部件320转动，偏心部件320驱动直线运动部件330做直线运动，以驱动蓄能机构200蓄能。蓄能机构200释放能量时，单向离合器部件340处于分离位置，蓄能机构200驱动直线运动部 件330做直线运动，并通过液压传动部件410带动击钉部件420撞击钉子。单向离合器部件340的作用在于使蓄能机构200在打钉时能够迅速释放能量，提高打钉时机构的运动速度，保证打钉效果。
单向离合器部件340在动力部件310驱动偏心轴转动时，总是处于连接位置。当偏心轴的转速超过动力部件310的输出轴转速时，单向离合器部件340总是处于分离位置。单向离合器部件340驱动偏心轴转动时，偏心轴驱动直线运动部件330使蓄能机构200储存能量，这时单向离合器部件340处在连接位置，动力部件310通过单向离合器部件340与偏心轴传动连接，此时，动力部件310的动力通过单向离合器部件340传递到偏心轴上，以驱动偏心轴运动。蓄能机构200释放能量时，蓄能机构200通过液压传动部件410带动击钉部件420完成击钉动作。同时直线运动部件330运动，直线运动部件330推动偏心轴转动，偏心轴的转速超过动力部件310的输出轴转速，单向离合器部件340处于分离位置，使偏心轴不能带动减速器312的输出轴转动。这样偏心轴能够在直线运动部件330的驱动下自由快速旋转，只消耗很少的能量，使得蓄能机构200上蓄积的大部分能量迅速通过液压传动部件410输出并撞击钉子，实现打钉操作。
本申请的打钉设备通过单向离合器部件340实现了驱动电机311动力的单向传递，保证了驱动电机311的驱动力能够驱动偏心轴带动直线运动部件330向蓄能机构200储存能量，同时又能保证打钉时蓄能机构200上的能量迅速释放，保证打钉效果。可选地，单向离合器部件340可以是楔块式单向离合器、滚柱式单向离合器、棘轮式单向离合器或者其他类型的单向离合器。

在图16和图17中，打钉设备100包括作为支撑结构的主架110、弹性蓄能机构140、蓄能驱动机构120、传动打钉机构150。蓄能驱动机构120、传动打钉机构150、弹性蓄能机构140均由主架110支撑连接。
可选择的，支撑结构可以是主架支撑结构，主架支撑结构包括外壳和主架110，外壳罩设在主架110上，通过外壳和主架110共同承载各个运动机构；当然，支撑结构也可以是壳体支撑结构，壳体支撑结构只包括外壳或壳体，外壳或壳体的内壁上设置有伸出部，各个运动机构均安装于伸出部上。
蓄能机构为弹性蓄能机构140。弹性蓄能机构140安装在支撑结构中的主架110上。蓄能驱动机构120安装在支撑结构中的主架110上，蓄能驱动机构120为本申请的打钉设备100的动力源，能够将能量存储在弹性蓄能机构140中，以实现驱动其他各个零部件运 动，进而实现打钉操作。传动打钉机构150可运动地安装在支撑结构中的主架110中，传动打钉机构150通过直线运动部件与弹性蓄能机构140连接。弹性蓄能机构140是用来实现能量的存储与释放的；蓄能时，蓄能驱动机构120驱动弹性蓄能机构140运动，使得能量存储在弹性蓄能机构140中；当能量释放时，弹性蓄能机构140能够通过直线运动部件驱动传动打钉机构150运动，通过传动打钉机构150将钉子打入基材。
具体的，蓄能驱动机构120包括动力部件、与动力部件传动连接偏心部件及与偏心部件连接的直线运动部件。动力部件固定在支撑结构中的主架110上，偏心部件安装在动力部件的输出轴上，直线运动部件连接偏心部件与弹性蓄能机构140。动力部件驱动偏心部件转动，偏心部件的转动通过直线运动部件变成直线运动，直线运动部件驱动弹性蓄能机构140储存能量；弹性蓄能机构140释放能量时，弹性蓄能机构140通过直线运动部件推动传动打钉机构150，带动传动打钉机构150撞击钉子。
较佳地，动力部件包括驱动电机121及减速器124，通过驱动电机121为弹性蓄能机构140的蓄能提供动力；减速器124设置在驱动电机121的输出轴上，偏心部件与减速器124的输出端连接，并连接至直线运动部件上，驱动电机121输出的运动通过减速器124减速后再传递到偏心部件上，这样能够增加扭矩，提高对弹性蓄能机构140的储能驱动力。可选地，减速器124为行星减速器。
本申请的打钉设备100可以与交流电源连接，实现打钉设备100的驱动，此时，驱动电机121为交流电机；当然，本申请的打钉设备100还可通过蓄电池来提供电能，实现打钉设备100的驱动，此时，驱动电机121为直流电机。
本实施例中，直线运动部件可以为挺柱126；当然，在本申请的其他实施例中，直线运动部件还可以为其他能够实现直线运动的结构。作为一种可选择的实施方式，偏心部件包括偏心轴122及套设于偏心轴122上的轴承125。偏心轴122与动力部件传动连接，轴承125与挺柱126抵接，动力部件驱动偏心轴122带动轴承125转动，轴承125带动挺柱126做直线运动。较佳地，轴承为滚动轴承125，以减少运动传递的摩擦损耗，使得挺柱126做无侧向摩擦力直线运动，保证很高的蓄能能效。蓄能时，偏心轴122的偏心运动能够带动轴承做偏心转动，带动挺柱126做直线运动，驱动压缩弹性蓄能机构140存储能量；弹性蓄能机构140释放能量时，推动挺柱126做直线运动，带动传动打钉机构150做打钉运动。
当然，在本申请的其他实施方式中，偏心部件包括转轴及套设于转轴上的偏心轴承。转轴与动力部件传动连接，偏心轴承与挺柱126抵接，动力部件驱动转轴带动偏心轴承转动，偏心轴承带动挺柱126做直线运动。蓄能时，挺柱126驱动弹性蓄能机构140存储能量；弹性蓄能机构140释放能量时，驱动挺柱126直线运动，带动传动打钉机构150运动，完成打钉动作。
可选地，支撑机构还具有导向功能，如在支撑结构的主架110上，为挺柱126上开设导向槽，导向槽为挺柱126做直线运动提供配合，使得挺柱126只能够沿导向槽的轴向做直线运动，以保证弹性蓄能机构140顺利蓄能与能量释放。
在本实施例中，偏心部件包括偏心轴122及设置在偏心轴122上的滚动轴承125。驱 动电机121能够驱动偏心轴122做转动，由于偏心轴122与挺柱126之间通过滚动轴承125连接，偏心轴122与滚动轴承125的内圈连接，滚动轴承125的外圈与挺柱126抵接。这样，偏心轴122转动时，偏心轴122的转动通过滚动轴承125的内圈实现，不会带动滚动轴承125的外圈转动，而且，偏心轴122的偏心运动能够带动滚动轴承125整体做偏心转动，进而使得挺柱126做直线运动。由于挺柱126的端部与弹性蓄能机构140连接，挺柱126的直线运动能够驱动弹性蓄能机构140蓄能；弹性蓄能机构140释放能量时，推动挺柱126做与蓄能时相反的直线运动，驱动传动打钉机构150运动，完成打钉动作。
本申请的打钉设备100通过偏心轴122与滚动轴承125配合，实现了对挺柱126无侧向摩擦的直线驱动，极大的消除了侧向力产生的摩擦损耗，进而实现高效驱动弹性蓄能机构140储存能量，提高了整个打钉设备100的能效，减小了驱动力，使得整体尺寸减小，重量减轻，更加便于携带。对于使用蓄电池作为能源的打钉设备100而言，减小摩擦损耗意味着大大的提高蓄电池单次充电的打钉数目，提高工作效率，提高了蓄电池的利用率。
举例说明，本申请的打钉设备100使用300瓦的电机在减速比约为100的行星减速器的条件下，采用本申请的方案驱动弹簧蓄能机构蓄能，获得了65焦耳的弹性蓄积能量，而目前电钉枪在同样条件下只能获得小于35焦耳的蓄能。可以理解的是，本申请的打钉设备100采用其他类型的电机相较于比目前的电钉枪在同样条件而言，也能够更好的蓄积能量，保证打钉效果。
参见图17至图19，图18为图17所示的打钉设备100中偏心轴122与滚动轴承125配合的主视图，图19为图18所示的偏心轴122与滚动轴承125配合的左视图。蓄能驱动机构120还包括单向离合器部件123，单向离合器部件123安装在动力部件的输出轴与偏心部件之间。弹性蓄能机构140储存能量时，单向离合器部件123处于连接位置，动力部件通过单向离合器部件123驱动偏心部件转动，偏心部件驱动挺柱126做直线运动，挺柱126驱动弹性蓄能机构140蓄能。弹性蓄能机构140释放能量时，单向离合器部件123处于分离位置，弹性蓄能机构140驱动挺柱126做直线运动，挺柱126驱动传动打钉机构完成打钉动作。单向离合器部件123的作用在于使弹性蓄能机构140在打钉时能够迅速释放能量，提高打钉时机构的运动速度，保证打钉效果。
单向离合器部件123在动力部件驱动偏心轴122转动时，总是处于连接位置。当偏心轴122的转速超过动力部件的输出轴转速时，单向离合器部件123总是处于分离位置。单向离合器部件123驱动偏心轴122转动时，偏心轴122驱动挺柱126使弹性蓄能机构140储存能量，这时单向离合器部件123处在连接位置，驱动电机121通过单向离合器部件123与偏心轴122传动连接，此时，驱动电机121的动力通过单向离合器部件123传递到偏心轴122上，以驱动偏心轴122运动。弹性蓄能机构140释放能量时，弹性蓄能器推动挺柱126运动，挺柱126推动偏心轴122转动，偏心轴122的转速超过动力部件的输出轴转速，单向离合器部件123处于分离位置，挺柱126驱动传动打钉机构150快速运动。弹性蓄能机构140释放能量，弹性蓄能机构140能够驱动挺柱126运动，进而带动偏心轴122运动，使单向离合器部件123处于分离位置，使偏心轴122不能带动减速器124的输出轴转动。这样偏心轴122能够在挺柱126的驱动下自由快速旋转，只消耗很少的能量，使得弹性蓄 能机构140上蓄积的大部分能量迅速通过传动打钉机构输出并撞击钉子，实现打钉操作。
本申请的打钉设备100通过单向离合器部件123实现了驱动电机121动力的单向传递，保证了驱动电机121的驱动力能够驱动偏心轴122带动挺柱126向弹性蓄能机构140储存能量，同时又能保证打钉时弹性蓄能机构140上的能量迅速释放，保证打钉效果。可选地，单向离合器部件123可以是楔块式单向离合器、滚柱式单向离合器、棘轮式单向离合器或者其他类型的单向离合器。在本实施例中，单向离合器部件123为棘轮式离合器。棘轮式离合器包括棘轮1231和棘爪1232，棘轮1231套设在减速器124的输出轴上，棘爪1232设置在偏心轴122上。棘轮式单向离合器在接合时，棘爪1232勾在棘轮1231上，减速器124将把驱动扭矩传递到棘轮1231上，棘轮1231转动并带动棘爪1232推动偏心轴122旋转，偏心轴122通过滚动轴承125推动挺柱126做直线运动，使得弹性蓄能机构140蓄能。蓄能完成后，偏心轴122通过死点后，棘轮式单向离合器处于分离的状态，棘爪1232越过棘轮1231，挺柱126被弹性蓄能机构140推动运动，偏心轴122不带动减速器124运动，而自行快速旋转，弹性蓄能机构140积聚的能量迅速通过打钉机构输出，完成打钉动作。棘轮式单向离合器还包括弹性件1233，弹性件1233设置在偏心轴122上，并与棘轮1231抵接，以保证单向离合器在蓄能和能量释放过程中的单向离合功能。
作为一种可实施方式，作为支撑结构的主架110包括用于安装蓄能驱动机构120的安装部及用于连安装传动打钉机构150的连接部。在本实施例中，安装部与连接部均为主架110的一部分。安装部具有安装孔，动力部件安装于安装部上，且偏心轴122穿设安装孔，安装部上具有安装空腔，弹性蓄能机构140设置于安装空腔中。而且，主架110可采用一体成型方式加工出来，减少装配工序，同时还能保证机构的可靠性。
进一步地，弹性蓄能机构140包括蓄能弹簧，主架110具有安装空腔，蓄能弹簧安装于支撑结构的安装空腔中。挺柱126可以驱动蓄能弹簧，使蓄能弹簧储存能量；蓄能弹簧释放能量时，蓄能弹簧释放使挺柱126反向运动。蓄能弹簧是用来实现能量的存储与释放的。蓄能弹簧的轴线方向与挺柱126的运动方向平行，避免蓄能时蓄能弹簧发生偏斜。蓄能弹簧的一端与安装空腔的顶壁相接触，另一端与挺柱126相接触。
较佳地，蓄能弹簧为压缩弹簧或气体弹簧。压缩弹簧或气体弹簧设置于支撑结构中，压缩弹簧或气体弹簧的一端与支撑结构抵接，压缩弹簧或气体弹簧的一端与挺柱126抵接。
参见图17和图20，图20为图17所示的打钉设备100中杠杆传动部件151的立体图。可选地，传动打钉机构150包括杠杆传动部件151及用于打钉的击钉部件，杠杆传动部件151的一端可转动地固定在支撑结构上，杠杆传动部件151具有中间支点1511，杠杆传动部件151在中间支点1511处与挺柱126连接，杠杆传动部件151的另一端与击钉部件传动连接。挺柱126带动杠杆传动部件151运动，使杠杆传动部件151驱动击钉部件撞击钉子。弹性蓄能机构140释放能量时，弹性蓄能机构140带动挺柱126运动，将能量迅速通过杠杆传动部件151输出，进而驱动击钉部件运动，使得击钉部件撞击钉子完成打钉操作。可选地，击钉部件包括撞针滑块，杠杆传动部件151的一端与撞针滑块连接，当然，在本申请的其他实施方式中，击钉部件还可为顶杆或者其他能够实现撞击钉子的部件。
进一步地，杠杆传动部件151的中间支点1511与杠杆传动部件151和击钉部件的连接 处之间的距离为杠杆传动部件151的中间支点1511与杠杆传动部件151和支撑结构的连接处之间的距离的5倍～10倍。杠杆传动部件151的中间支点1511到两端的距离能够调节杠杆传动部件151的输出速度，当杠杆传动部件151的中间支点1511与杠杆传动部件151和击钉部件的连接处之间的距离大于杠杆传动部件151的中间支点1511与杠杆传动部件151和支撑结构的主架110的连接处之间的距离后，能够将弹性蓄能机构140释放时的运动速度加倍成击钉部件的运动速度，具体的，弹性蓄能机构140释放时的运动速度加倍成5倍～10倍的击钉部件的运动速度，使得击钉部件撞击钉子的打钉速度是弹性蓄能机构140的运动速度的5倍～10倍，进而提高撞针的撞击速度，使得打钉效果大大增加。
可选地，传动打钉机构150还包括作为击钉机构的滑道滑块机构，滑道滑块机构与支撑结构的主架110相连，滑道滑块机构与杠杆传动部件151连接。弹性蓄能机构140释放的能量通过挺柱126传递到杠杆传动部件151上，使得杠杆传动部件151能够驱动滑道滑块机构中滑块运动，进而驱动击钉部件即撞针将钉子打入基材中。具体的，滑道滑块机构包括滑道以及可滑动设置于滑道中的滑块。滑块与击钉部件固定连接，滑块在杠杆传动部件151的作用下在滑道中沿轴向做直线运动，进而使得撞针撞击钉子，实现打钉动作。
杠杆传动部件151上还设置滚轮152，滚轮152可滚动地设置在杠杆传动部件151与滑块相连接的一端上。滑块上开设沿杠杆传动部件151运动方向的滑槽，滚轮152可滚动地设置在滑槽中。由于弹性蓄能机构140释放的能量时，挺柱126会带动杠杆传动部件151的端部做弧形运动，为了避免杠杆传动部件151带动滑块的运动与滑道发生干涉，在杠杆传动部件151与滑块的连接处设置滚轮152，在滑块上开设滑槽，滚轮152能够在滑槽中滚动，这样杠杆传动部件151的端部轨迹为弧线时，杠杆传动部件151能够通过滚轮152在滑槽中移动，避免杠杆传动部件151在驱动滑块运动时产生干涉及减少侧向力，使得杠杆传动部件151能够无障碍的驱动滑块沿滑道做直线运动，保证滑块的高速运动，进而提高滑块驱动击钉部件的撞击速度，保证打钉效果，同时，杠杆传动部件151与滑块通过滚轮152配合还能降低摩擦，以减小打钉时的摩擦损耗。
更进一步地，传动打钉机构150还包括连杆，连杆的一端与杠杆传动部件151转动连接，连杆的另一端与挺柱126转动连接。也就是说，杠杆传动部件151的中间支点1511通过连杆与挺柱126连接，使得弹性蓄能机构140释放的能量通过挺柱126与连杆传递到杠杆传动部件151上，保证杠杆传动部件151运动灵活可靠。
本申请的另一实施方式中，打钉机构还可包括带传动部件及击钉器。也就是说，通过带传动部件替换杠杆传动部件151，参见图21。需要说明的是，本申请的杠杆传动部件151还可以替换除带传动部件之外其它能够实现弹性蓄能结构140的能量输出给击钉部件的结构。
具体的，带传动部件包括传动带153，击钉部件包括击钉器154及套设于击钉器154上的复位弹簧1541。挺柱126上设置两个动滑轮1261，滚动轴承125的外圈与挺柱126抵接，动滑轮1261可转动地连接在挺柱126上。传动带153绕过两个动滑轮1261和击钉器154尾部连接，且传动带153的两端固定在作为支撑结构的主架110上。弹性蓄能机构140位于传动带153与挺柱126围成的空间，且弹性蓄能机构140抵接在挺柱126与主架 110上。复位弹簧1541套设在击钉器154上，并抵接在主架110上。偏心轴122的偏心运动通过滚动轴承125带动挺柱126做上升运动时，压缩弹性蓄能机构140存储能量，同时，两个动滑轮1261上移，放松传动带153，击钉器154在复位弹簧1541回复力作用下上移，张紧传送带153；弹性蓄能机构140释放能量时，挺柱126做下降运动，动滑轮1261向下移动张紧传动带153，推动击钉器154加速下移，形成撞击钉子的打击运动，完成将钉子打入基材的动作。
可选地，打钉设备100还包括储钉盒170，储钉盒170与支撑结构相连，储钉盒170的出料口对应撞针设置。储钉盒170是用来存储钉子的，打钉设备100还包括钉子自动输送机构，自动输送机构设置在储钉盒170中，以实现钉子的自动输送。打钉设备100工作时，撞针将钉子打到基材里后，储钉盒170中的自动输送机构将钉子送到撞针处，杠杆传动部件151再次驱动击钉部件撞击钉子，将钉子打钉到对应位置的基材上，如此循环往复，实现自动化操作，方便实用。
本申请的打钉设备100进行打钉作业时，驱动电机121产生的动力通过减速器124减速后输出到单向离合器部件123上，单向离合器部件123处于连接位置，单向离合器部件123的棘轮1231与偏心部上的棘爪1232相配合驱动偏心轴122转动，偏心轴122通过滚动轴承125的作用带动挺柱126做直线运动，并压缩弹性蓄能机构140，使得蓄能弹簧存储能量；当偏心轴122转动通过死点，蓄能弹簧释放能量，挺柱126在弹性蓄能机构140的驱动下运动，由于棘爪1232与棘轮1231分离，偏心轴122不带动减速器124运动，而自行快速旋转，使得蓄能弹簧积聚的能量迅速通过杠杆传动部件151输出，带动滑块沿滑道运动，滑块驱动击钉部件运动，使得击钉部件撞击钉子，完成打钉动作。
