Description

射钉枪用传动部件、防卡齿组件以及射钉枪 技术领域
本发明属于紧固工具技术领域，具体涉及一种射钉枪用传动部件、防卡齿组件以及射钉枪。
背景技术
射钉枪是一种紧固工具，多用于建筑施工，目前，应用广泛的一种射钉枪为采用锂电池的电动射钉枪，这种射钉枪通过驱动电机以及相应的传动结构来推动活塞，进而活塞压缩供力弹簧或者压缩气体进行蓄能，射钉时，供力弹簧或气压驱动活塞运动，进而带动安装在活塞上的撞针将枪钉撞击射出实现打钉。
现有的射钉枪中，传动结构推动活塞一般是采用齿条和齿轮的传动方式，即在撞针上设置齿条，在驱动电机上设置缺齿齿轮，驱动电机通过减速增扭装置带动缺齿齿轮转动，由于齿条与缺齿齿轮上的齿牙相互啮合，从而在齿轮转动的过程中会带动齿条进行横向移动，以实现对供力弹簧或气体的压缩进行蓄能。当齿轮转动至与撞针之间无齿啮合(即缺齿部分与撞针相对应)的状态下，供力弹簧或气压会将撞针推出，撞针会将枪钉打出实现打钉。
根据上述原理所制成的射钉枪，在某些特定的情况下容易出现以下问题：当齿条上的齿槽与齿条未精准啮合，即齿牙直接碰撞到齿条上但未进入齿槽时就会造成卡齿，此时如果使用者在进行维修解除故障时就会容易造成枪钉意外击发而造成人身伤害，安全性不高。
发明内容
为解决上述问题，提供一种可预防卡齿的射钉枪用传动部件，设置有此种传动部件的防卡齿组件以及设置有此种防卡齿组件的射钉枪。

本发明提供的射钉枪用传动部件，还可以具有这样的技术特征，其中，齿销具有n个，齿销设置在转动部分的边缘处，
第一个齿销与相邻的第n个齿销之间形成第一间隙，其余的齿销中，每个齿销与相邻的齿销之间具有相同距离的第二间隙，第一间隙大于第二间隙。

本发明提供的射钉枪用传动部件，还可以具有这样的技术特征，其中，转动部分为截面形状为“工”字型的圆盘，该圆盘的边缘处设有若干用于安装齿销的安装孔，
其中一个安装孔为活动孔，该活动孔呈长圆形，
齿销为圆柱形，其余的安装孔具有与齿销相适配的形状。
本发明还提出了一种射钉枪用防卡齿组件，设置在射钉枪内，用于控制射钉枪进行射钉， 具有这样的技术特征，包括：击打部件，用于推动射钉枪的枪针打入目标物，传动部件，用于与击打部件配合并带动击打部件沿着打入方向做直线运动，其中，传动部件为如上所述的射钉枪用传动部件，击打部件上具若干齿槽，在传动部件转动过程中，齿销嵌入齿槽内以实现配合。

本发明提供的射钉枪用防卡齿组件，还可以具有这样的技术特征，其中，扣合部分具有与齿销相适配的弧线型形状，导入部分具有一段直线型形状，且该直线与弧线相切，齿槽的数量与齿销的数量相等。
本发明还提出了一种射钉枪，具有这样的技术特征，至少包括：射钉枪用防卡齿组件，该射钉枪用防卡齿组件为如上所述的射钉枪用防卡齿组件。
发明作用与效果
根据本发明所提出的射钉枪用传动部件、防卡齿组件以及射钉枪，由于在传动部件的配合部分具有若干个齿销，可通过该齿销与击打部件相配合来带动击打部件移动，采用齿销相比采用齿轮的齿牙具有更好的配合度，且若干个齿销中至少具有一个活动齿销，当活动齿销与击打部件相配合时若没有位于精准位置，则活动齿销会进行移动，从而让活动齿销配合到位，防止卡齿，避免枪钉误射，提升安全性。

如图5-图9所示，若干齿销4312中含有至少一个活动齿销4312’，转动部分4311上开设的安装孔中有一个安装孔为供该活动齿销4312’移动的长圆形的活动孔43112(如图5和图6A所示)，其他的安装孔与圆柱形的齿销具有相适配的形状。活动齿销4312’与转动部分4311之间设有弹性组件，该弹性组件具有：第一弹簧441，一端作用于转动部分4311，另一端作用于活动齿销4312’，转动部分4311内开设有用于安装第一弹簧441的容纳腔43113(如图6B所示)。弹性组件还具有位于第一弹簧441与活动齿销4312’之间的顶块442，顶块442朝向第一弹簧441的一侧设置有供第一弹簧441插入的限位孔4421或者供第一弹簧441套设的限位柱(本实施例的图7中为限位孔4421)；顶块442朝向活动齿销4312’的一端设有与活动齿销4312’接触的作用面。
在本实施例中，齿销4312具有n个，每个齿销4312一一对应一个齿槽4112，以活动齿销4312’为第一个齿销，用于嵌入第一个齿槽4112’中，将第一个齿销设置成可活动的，可以保证第一个齿槽4112’能够被更好地嵌入。如在触发时，活动齿销4312’若正好碰触到齿块4111上，由于活动齿销4312’被设置成可活动的，因此在齿块4111的反作用力下会推动活动齿销4312’在活动孔43112内做细微移动，并在第一弹簧441的作用下嵌入第一个齿槽4112’中(如图7所示)，使得第一个齿销(活动齿销4312’)和第一个齿槽4112’能够正常配合，以避免产生卡齿等情形。当齿销4312跟随转动部分4311进行持续的逆时针方向转动时，每一个齿销逐步嵌入每一个对应的齿槽内，从而将带动击打部件411逐渐向右移动(如图8和图9所示)。
如图6A所示，n个齿销4312排布在转动部分4311的边缘处，第一个齿销(活动齿销4312’)与相邻的第n个齿销4312”之间形成第一间隙L1，其余的每个齿销4312与相邻的齿销4312之间具有相同距离的第二间隙L2(第一个齿销与相邻的第二个齿销之间、第n个齿销与相邻的第n-1个齿销之间的间隙也为L2)，第一间隙L1的长度大于第二间隙L2的长度。当转动部分4311运行到第一间隙L1朝向击打部件411时，由于第一间隙L1之间没有设置齿销，因此此时的转动部分4311与击打部件411处于空齿状态，而处于该状态下的击打部件411就可以被蓄能机构触发沿击打方向移动，从而将枪钉打出。另外，相邻齿槽4112之间具有相同的距离，该距离与第二间隙L2之间具有相对应的关系，即相邻齿槽4112之间的横向长度与第二间隙L2的弧线长度几乎相等，从而使得每个齿销4312能够与每个齿槽4112相对应。

形轮廓，扣合部分4112b位于导入部分4112a的一侧具有一段直线型的形状，且该直线与弧线形的导入部分4112a相切；而扣合部分4112b位于齿块4111的一侧形成挡沿，用于与齿销4312扣合以实现配合。在转动部分4311转动过程中，每个齿销4312均顺着对应的齿槽4112的导入部 分4112a滑入扣合部分4112b内，在挡沿的阻挡下，齿销4312在跟随转动部分4311转动过程中会推着击打部件411进行移动。齿槽4112的数量大于或等于齿销4312的数量，使得齿销与齿槽之间能够存在空齿状态，从而便于撞针部分沿着击打方向将枪钉打出。
图10是本发明实施例中传递机构与击打机构配合结构的示意图。
如图10所示，限位部分433为与转动部分4311同轴设置的棘轮，棘轮与转动部分4311均套设在射钉枪的控制电机的输出轴51上，并且通过插销将棘轮与转动部分4311固定连接在一起，在控制电机的带动下与转动部分4311进行同步转动，棘轮的外周设有若干棘齿4331，限位部件432具有与棘齿4331相互配合的棘爪4321，用于嵌入相邻的棘齿之间。如图10所示，相邻的棘齿4331之间的间距小于齿槽4112的宽度，使得棘爪与棘齿配合的时候能够更加紧密牢固，不易脱出。实际过程中，相邻的棘齿4331之间的间距也可以设置成与齿槽4112的宽度相等，也同样能达到配合的效果，但配合紧密度没有本实施例中将相邻的棘齿4331之间的间距设置成小于齿槽4112的宽度的效果好。
本实施例采用上述棘爪与棘齿的相互配合方式相比现有技术中采用棘爪直接与齿槽4112来配合要更加的紧密牢固，因为棘齿4331之间的间距远小于齿槽4112的宽度，不易出现现有技术中棘齿脱离的问题。实际中，限位部分433也可以是直接一体设置在转动部分4311上的棘齿(即将转动部分4311设置地更厚一些，直接在转动部分4311靠上部分的外周设置棘齿，此种实施方式未在图中示出)，此种方式既能保证限位部分433与转动部分保持同步转动，又能减少零件，但对转动部分的加工工艺有更高的要求。
如图4所示，蓄能机构42包括储能部件45、充气部件46和泄压部件47，储能部件45具有外缸体451和内缸体452，外缸体451含有外缸本体4511和盖设在外缸本体4511后端的后盖体4512，后盖体4512可拆卸设置，外缸本体4511的内侧中空设置形成气腔453，气腔453用于存储空气或氮气等气体。外缸本体4511的内部还安装有内缸体452。内缸体452呈长筒型的圆环结构，内缸体452内部安装有击打机构41，击打机构41的活塞部分412外周紧贴内缸体452的内壁，且在活塞部分412与内缸体452的内壁之间压设有密封圈413，活塞部分412固定有击打部件411，击打部件411的前端延伸出内缸体452及外缸本体4511的前端部与传动部件431配合。如图4所示，活塞部分412和密封圈413将内缸体452内部分成两个分离的部分，分别为第一腔体4521和第二腔体4522，且这两个部分的容积在活塞部分412移动的过程中会进行变化，第二腔体4522与气腔453相通，第一腔体4521则与第二腔体4522分离并且与外界相联通，内缸体452的前端设置有连通第一腔体4521与外界的内通孔4523。将后盖体4512设置成可拆卸的形式，方便将外缸体进行拆卸，从而替换或维修内部的击打机构41。为了让气腔内部形成密封空间，在后盖体4512与外缸本体4511的连接处设置有第一密封件4513，增强后盖体4512与外缸本体4511之间的连接紧密性，避免产生气腔453漏气等情况，在本实施例中，第一密封件4513选用密封圈(如图12所示)。
气腔453内充有空气或氮气，由于击打机构41安装在内缸体452内部，当击打部件411被传动部件431带动进行移动过程中，活塞部分412会朝向第二腔体4522的方向移动，第二腔体4522的容积逐渐缩小，从而位于气腔453内的气体被压缩，使得气腔内部的气压逐渐变大，实现能量的积蓄。当传动部件431的转动部分4311转动到第二间隙朝向击打部件411(即击打部件411处于空齿状态时)，在气腔453内的气压之下，可将击打机构41沿着击打方向推出，从而实现打钉。
图12是图4的B处局部放大图。
为了方便对气腔453内的气体进行补充，特在外缸本体4511靠近后盖体4512的一端设置有充气部件46。如图4和图12所示，外缸本体4511靠近后盖体4512处开设有一进气口4514，并在进气口4514一侧的外缸本体4511上开设有一个联通气腔453和进气口4514之 间的进气通道4531。充气部件46为一中部开设有充气通道461的充气嘴，充气嘴内端插设在进气口4514处，外端延伸出外缸本体4511裸露在外侧，方便用户对充气嘴进行充气。
图13是图4的C处局部放大图。
外缸本体4511的前端一侧设置有泄压部件47，在本实施例中，泄压部件47为一自动泄压阀，当气腔453内的气压逐渐增大并达到设定的临界值时，自动泄压阀会自动开启对气腔453内进行泄压，使得气腔453内的气压始终保持在该临界值以内，以保证外缸本体4511内部的安全性。另外，泄压部件47的外端裸露在外缸本体4511的外侧，在用户需要对外缸体进行拆卸检查时，也可先依靠人工将泄压阀打开，将气腔453内部的气体排出再进行拆卸，避免因为气腔内部气压过高，导致击打部件被误发伤到用户，增强产品的安全性。
具体的，如图13所示，外缸本体4511的前端一侧开设有泄压腔4515，外缸本体4511上开设有联通该泄压腔4515与气腔453的泄压通道4532。自动泄压阀具有泄压阀体471、泄压阀芯472、泄压弹簧473，泄压阀体471一端固定安装在泄压腔4515内，另一端延伸出并裸露在外缸本体4511的外侧。泄压阀体471中部开设有与泄压腔4514联通的泄压容腔474，泄压阀体471侧面设置有联通泄压容腔474及外界的泄压孔475，泄压阀芯472通过泄压弹簧473移动设置在泄压容腔474内，泄压容腔474的侧壁成型有与泄压阀芯472配合的限位阻挡面4741。在自动泄压阀关闭的状态下，泄压阀芯472在泄压弹簧473的作用下堵在泄压容腔474与泄压腔4515的联通处，此时，泄压阀芯472与限位阻挡面4741贴紧，气腔453内的气体无法排出。当气腔453内的气压逐渐增大并超过预设值时，气体会经过泄压通道4532及泄压腔4515进入泄压容腔474并逐步推动泄压阀芯472，当泄压阀芯472被推动离开限位阻挡面4741形成间隙时，气体可从该间隙经过并从泄压孔475排出，从而对气腔453内部进行泄压。当气腔453内的气压下降到预设值后，在泄压弹簧473的作用下，泄压阀芯472会被推动复位，使其与限位阻挡面4741紧贴。自动泄压阀在工作时无需人工启动，能够根据气腔453内部的变化自动开启，对气腔453形成保护。
图14是图4的D处局部放大图。
内缸体452的前端与外缸体451前端固定连接，并且在连接处设置有一缓冲垫454，缓冲垫454中部开设有供击打部件前端伸出的贯通孔4541。缓冲垫454的内端面用于对活塞部分412进行缓冲，活塞部分412被气腔453内的气压推动向前移动(击打方向)，活塞部分412可以一直移动到被缓冲垫454阻挡为止，缓冲垫454可给活塞部分412形成阻挡和缓冲，避免其直接与外缸本体的内侧面撞击，对活塞部分412形成保护。
如图13和图14所示，缓冲垫454的具体安装结构为：内缸体452为一截面呈圆环形的套筒结构，缓冲垫454的外周成型有安装凸环4542，外缸本体4511的前端的内侧形成有限位面4516以及限位凸台4517，缓冲垫454的前端抵设在该限位面4516上(如图4所示)，内缸体452的前端面抵设在安装凸环4542以及限位凸台4517上，从而实现缓冲垫454、内缸体452以及外缸本体4511三者之间的连接。如图14所示，内缸体452外周和外缸本体4511内壁之间设置有第三密封件455，第三密封件455为两个密封圈，并且外缸本体4511的前端在内通孔4523的外侧设置有外通孔4518，内通孔4523和外通孔4518相联通，从而将第一腔体4521与外界相联通。在横向截面上，内通孔4523和外通孔4518位于第三密封件的前侧，气腔453位于第三密封件的后侧，第三密封件455不仅能够起到加强连接紧密性的作用，还能够将气腔453与第一腔体4521隔开，形成两个独立的空间，避免气腔453与外界相联通而受到外界气压的影响。
图11是图3的A处局部放大图。
图15是本发明实施例中外缸本体的结构图。
图16是本发明实施例中外缸本体的结构剖视图。
如图15所示，外缸本体4511的前端设置有安装部分4519，安装部分4519成型有用于安装传动部件的凹槽4519a，凹槽4519a具有与传动部分的转动部分相适配的形状，即圆环形。安装部分4519位于凹槽4519a的一侧设置有安装槽4519b，限位部件432的棘爪4321安装在安装槽4519b中，凹槽4519a朝向安装槽4519b的一侧开设有供棘爪4321一端穿过的孔位4519c。
如图11所示，棘爪4321具有定位端4321a、限位端4321b以及连接段4321c，定位端4321a通过一转轴4321d转动安装在安装槽4519b内，限位端4321b穿过凹槽4519a的侧壁上的孔位4519c延伸进入凹槽4519a内部与位于凹槽4519a内的棘轮上的棘齿4331相互配合；连接段4321c为连接定位端4321a和限位端4321b的部分，连接段4321c的一侧设置有第二弹簧4322，安装部分4519上插设有一定位螺钉4323，用于给第二弹簧4322的一端提供支撑，第二弹簧4322的两端分别抵设在定位螺钉4323和连接段4321c上，在第二弹簧4322的作用下，能够让棘爪4321的限位端4321b更好地与棘齿4331相配合，使限位端4321b嵌设在棘齿4331内，避免棘轮的反向转动。同时，如图15所示，安装部分4519上对应转轴4321d及定位螺钉4323开设有定位孔4519d、4519e，分别用于安装转轴4321d及定位螺钉4323。棘齿4331与棘爪4321的配合能够阻止棘轮进行反向转动，由于棘轮与转动部分同轴设置，即可以避免转动部分进行反向转动，从而可以避免击打部件被误射，具有更强的安全性。
图17是本发明的实施例中内缸体的结构图。
图18是图4的E处局部放大图。
如图4所示，内缸体452安装在外缸本体4511内部，内缸体452的前端通过第三密封件455与外缸本体4511内壁相连并锁紧限位。为了能够让内缸体452更加稳定地设置在外缸本体4511内部，如图17所示，在内缸体452远离第三密封件455的一端设置有凸环4524，凸环4524的一侧设置有一圆形的定位环456，定位环456上开设有供气体穿过的气孔4561。如图18所示，定位环456的内周套设在内缸体452的外周，并且一侧被凸环4524抵住，定位环456的外周则被后盖体4512朝向外缸本体4511一侧的端面进行阻挡，从而使得定位环456能够被限位在后盖体4512与凸环4524之间，增强结构之间的连接稳定性。第三密封件455和定位环456分别在内缸体452的前后两端，对内缸体452的前后两端都形成支撑，让内缸体452能够更加稳定地固定在外缸本体4511的内部。
本实施例的工作原理：
射钉枪的控制装置50中的控制电机开启，带动传动部件431进行转动，转动部分4311在转动过程中，从第一个齿销(活动齿销4312’)开始逐步与击打部件411上的齿槽4112相互配合，从而带动击打部件411及活塞部件412在内缸体452内部朝向击打方向的反方向进行移动，活塞部件412在移动过程中，第二腔体4522的容积逐渐变小，从而对气腔453内的气体进行压缩，气腔453内的气压逐渐升高进行蓄能，当转动部分4311持续转动到与击打部件411之间形成空齿状态时，在气腔45内的气压推动下，将活塞部件412及击打部件411沿着击打方向推出，从而让击打部件411将枪钉打出完成射钉工作。
在转动部分4311转动过程中，棘轮也跟随转动部分4311进行转动，棘爪4321与棘轮外周的棘齿4331相互配合，对棘轮起到阻止反转的作用，从而较好的避免了在工作过程中击打部件误发的情况，增强安全性。
实施例作用与效果
根据本实施例提出的射钉枪用传动部件、防卡齿组件以及射钉枪，由于本实施例的传动部件431含有转动部分4311和配合部分，转动部分用于与射钉枪的驱动电机相连，并通过驱动电机驱动进行转动，配合部分为若干分布在转动部分的齿销4312，通过齿销4312与击 打部件411的齿槽4112来配合，从而实现传动部431件与击打部件411之间的配合，驱动击打部件411进行移动。采用齿销4312与齿槽4112的配合相比齿轮与齿条的配合更易咬合因此传动更加稳定。同时，本实施例的齿销4312至少有一个为活动齿销4312’，在传动部件431与击打部件411相互配合的时候，齿销4312需要逐一嵌入击打部件411的齿槽4112内，在实际使用过程中，容易出现齿销4312与齿槽4112没有完全对齐，导致齿销4312直接与齿块4111相碰撞无法正常咬合驱动而卡齿的情况，将齿销4312设置成可活动的，活动齿销4312’与齿块4111发生碰撞时活动齿销4312’在撞击力的作用下会进行细微移动，精准地嵌入到齿槽4112内，避免传动部件431与击打部件411卡住，进而避免了因两者卡住而产生枪钉的意外击发而造成的人身伤害，进一步增强安全性。
本实施例由于在传动部件431上直接设置与用于限制击打部件411移动的限位部件432配合的限位部分，从而无需再在击打部件411上另外设置与限位部件432配合的结构，简化了击打部件411的结构，且由于限位部件432与击打部件411之间没有直接接触，因此在击打部件411发射时无需解除限位部件432之间的限位关系，即无需在限位部件432处设置专门驱动限位部件432转动的电磁阀等驱动装置，简化结构，降低成本，从而也解决了因电磁阀失效带来的缺陷，让整个射钉枪在工作时更加高效、稳定及安全。
本实施例的限位部分433为与转动部分同轴设置的棘轮，且外周设有若干棘齿4331，限位部件432为与棘齿4331相互配合的棘爪4321，用于嵌入相邻的棘齿4331之间，将棘轮设置成与转动部分4311同轴，使得转动部分4311与棘轮能够进行同步转动，棘爪4321与棘轮相互配合从而可以限制转动部分4311反向转动，进而实现对击打部件411移动的限制，提升安全性，且棘轮和转动部分4311直接由同一个驱动电机带动，无需另置动力源，简化结构，降低成本，减轻重量，方便携带和使用。
本实施例的棘轮上的棘齿4331之间的间距小于击打部件411上的齿槽4112的宽度，相比棘爪4321直接与齿槽4112配合具有更稳定的连接性，间距越小，棘爪4321配合的紧密性及精确性更高，大大减少甚至杜绝了棘爪4321脱齿的肯能性，从而降低击打部件411误发的概率，提升安全性能。
本实施例的蓄能机构包括内外两个缸体，内外两个缸体之间设置气腔，内缸体452设置在外缸体451的外缸本体4511内，内缸体452内部设置击打机构41，通过传递机构43带动击打机构41来实现气腔内气压变化来实现打钉，外缸本体4511的后侧设置有可拆卸的后盖体4512，方便拆卸从而对位于内缸体452内部的击打机构41进行维护或替换。
本实施例的蓄能机构42由于设置有通向气腔453的泄压部件47，当气腔453内的气压增加并超过预先设定好的安全临界值时，泄压部件47会自动开启对气腔453内进行泄压，使得气腔内的气压能够始终处于安全临界值以内，保证设备的安全性能；同时，蓄能机构42还设置有通向气腔453的充气部件46，可以在有需要时对气腔453内部进行充气，非常方便。
本实施例的蓄能机构的外缸体451直接一体成型有安装部分4519，安装部分4519用来安装传动部件431，将安装部分4519制成一个通用件，在需要适用不同的枪针时只需要替换相适应的击打部件411及传动部件431即可，而无需更换整个设备，适用性广；当用户需要进行多种情况的施工时，无需携带各种不同枪钉的射钉枪，只需要携带适配的击打部件及传动部件即可，携带非常便捷。
上述实施例仅用于举例说明本实施例的具体实施方式，而本发明不限于上述实施例的描述范围。
