Description

一种双把式拉铆枪 技术领域
本发明涉及铆接工具技术领域, 特别是涉及一种双把式拉铆枪。 背景技术
目前, 双把式拉铆枪被广泛应用于建筑、 汽车、 船舶、 飞机、 机 器、 电器、 家具等产品的铆接工序中, 通常包括铆枪座, 设置于铆枪 座两侧的两个把手, 设置于铆枪座前端的铆钉调节机构, 安装于所述 的铆钉调节机构内的铆钉抓持机构, 活动插设于所述的铆枪座的中心 孔内的拉杆, 通过螺栓固定在拉杆上的固定块以及连接固定块和把手 的连杆。 其中, 铆钉调节机构通常由套简、 调节螺帽和铆钉导嘴组成。 铆钉抓持机构通常由抓片座、 抓片、 顶杆和弹簧组成。 三瓣抓片设置 于抓片座前部的内腔中。 抓片座的后部与拉铆枪的拉杆连接。 当拉铆 枪的拉杆伸缩机构使拉杆向前时, 于拉铆枪拉杆的前端与拉杆连接的 抓片座同时向前。 铆钉从拉铆枪前端的导嘴插进, 因抓片座内腔有锥 型斜度, 导嘴将抓片往后推向抓片座内腔直径大的部位, 抓片松开, 抓片后部的顶杆顶住抓片, 铆钉随后就插入抓片中。 当拉铆枪的拉杆 伸缩机构使拉杆向后缩回时, 带动抓片座向后。 这时, 抓片座内腔的 锥型斜度使抓片闭紧同时将铆钉拔起。
但是, 现有的双把式拉铆枪的把手和拉杆较长, 拉杆前、 后两头 均伸出于铆枪座外。 把手和拉杆较长不仅使整把拉铆枪长度增大而导 致其体积增大, 不便于灵巧使用和携带、 包装及运输, 而且由于拉杆 前、 后两头均伸出于铆枪座外, 使拉铆枪操作时拉杆在伸缩活动时稳 定性差, 容易出现偏移及歪斜, 影响拉铆枪工作效率。
另外, 铆钉抓持机构的三瓣抓片斜插于抓片座内腔中, 由于抓片 座内腔的截面为圆形, 且没有设置与抓片相对应的导槽, 当拉铆枪操 作时, 拉铆枪拉杆前后伸缩, 抓片也随着在抓片座内腔中前后伸缩, 容易使抓片在抓片座内腔中滑动, 导致抓片稳定性、 定向性差, 甚至 还会出现抓片错位卡住现象。 发明内容
本发明要解决的问题是提供一种双把式拉铆枪, 以克服现有的双 把式拉铆枪体积大、 抓片稳定性、 定向性差的缺陷。
为达到上述目的, 本发明的技术方案提供一种双把式拉铆枪, 所 述拉铆枪包括铆枪座( 6 ), 设置在所述铆枪座( 6 )前端的铆钉调节机 构, 安装于所述铆钉调节机构内的铆钉抓持机构, 铆钉抓持机构固定 在拉杆(8) 的前端; 一端通过螺杆轴 (5)分别于所述铆枪座 (6)两 侧的配合孔与该铆枪座相铰接的两个把手 (9), 活动插设于所述铆枪 座 (6) 的中心孔 (12) 内的拉杆(8); 所述拉杆(8) 的全部或大部 带后部, 和该拉杆末端上的拉杆伸缩机构之固定片(7)及一端分别铰 接该固定片 (7) 两侧、 另一端分别靠近所述螺杆轴 (5) 旁铰接所述 把手(9) 头部的连杆(20)均安设于所述铆枪座(6)腔体内; 所述 固定片 (7)嵌设于所述的拉杆(8)末端的固定槽 (11) 中; 所述连 杆(20)的一端通过第二销杆(19)分别与所述的固定片(7)的左右 两侧铰接、 另一端通过第一销杆(21) 与所述把手 (9) 头部相铰接, 所述的把手 (9) 头部设有于与螺杆轴 (5)和第一销杆(21 ) 配合的 孔; 所述螺杆轴(5)与所述第一销杆(21 )之间的平行距离小于或等 于 9毫米; 所述的铆枪座(6)两侧开有把手配合槽(612); 所述把手 (9)的长度小于或等于 260毫米; 所述的第一销杆(21)在把手配合 槽内其端部不超出把手配合槽 (612)。
其中, 所述铆钉抓持机构包括: 抓片座(2)、设于所述抓片座(2) 内腔中的抓片(1)、 抓片座(2) 中顶住抓片(1) 的顶杆(3)和顶杆 (3)后部的复位弹簧 (4), 抓片座 (2) 与抓片配合的内腔为正六角 锥形, 其六角锥形的角槽构成抓片导槽 (22), 所述抓片 (1 )嵌入所 述的抓片导槽 (22) 中。
其中, 所述抓片座(2)后部的内壁上设有与拉铆枪拉杆的头部相 适配的螺紋。
其中, 所述铆枪座 (6) 末端连接有集钉瓶 (10)。
其中, 所述把手( 9 )上开设有与各种规格的铆钉导嘴( 15 )相适 配的预留铆钉导嘴放置孔(16), 所述预留铆钉导嘴放置孔(16)内放 置有与之相适配的预留铆钉导嘴 (17)。
其中, 所述螺杆轴 (5) 与所述第一销杆(21 )平行且不接触。 其中, 所述铆枪座(6) 由前铆枪座(61)和后铆枪座(62)配合 构成, 所述后铆枪座(62)前部的把手配合槽插入所述前铆枪座(61) 后部的把手配合槽中, 并有一连接件将所述前铆枪座 (61) 和后铆枪 座 ( 62 )结合。
其中, 所述将前铆枪座 (61) 和后铆枪座 (62)结合的连接件是 所述螺杆轴 (5), 所述螺杆轴 (5)将两个把手 (9)铰接于所述铆枪 座 (6) 两侧的把手配合槽 (612) 内, 且所述的第一销杆(21)在铆 枪座两侧的把手配合槽 (612) 内。
其中, 所述拉杆(8)末端的固定槽(11)底面是四个平面, 每两 个相邻的所述的平面相互垂直; 所述固定槽 (11) 中嵌设有与之相适 配且相互平行的两个固定片(7), 两个固定片(7)两侧的中间铰接着 所述连杆( 20 )。
其中, 所述的拉杆(8) 末端的固定槽 (11)为圆环形槽。
与现有技术相比, 本发明的技术方案具有如下优点:
本发明的铆枪座两侧开有把手配合槽, 两个把手分别通过螺杆轴 于所述铆枪座两侧与铆枪座相铰接, 固定片两侧的连杆分别在铆枪座 腔体内与把手相铰接, 这样避免了把手张合时连接件端部与螺杆轴头 部的相互抵触, 使所述的螺杆轴与所述连接件的第一销杆近距离而不 碰着地平行, 所述螺杆轴与第一销杆之间的距离小于或等于 9毫米。 从而根据杠杆原理, 第一销杆与螺杆轴的距离越小, 力臂就越大, 把 手的长度就可以越短, 使把手的长度小于或等于 260毫米。 因此, 本 发明减小了整体体积, 节约了原材料, 并且不会影响使用效果。, 同时 因为第一销杆在铆枪座把手配合槽内活动, 其第一销杆轴端部不超出 铆枪把手配合槽的高度, 使第一销杆与螺杆轴的距离尽量靠近变为现 实。
另外, 本发明的拉杆全部或大部带后部, 和在该拉杆末端上的拉 杆伸缩机构的固定片、 该固定片两侧分别铰接所述把手头部的连杆均 安设于所述的铆枪座腔体内, 这使拉杆在伸缩活动时稳定性大幅度增 强, 避免拉杆出现偏移及歪斜, 使拉铆枪工作效率提高。 另外, 拉杆 伸缩机构的零部件安设于所述的铆枪座腔体内, 使拉杆的后部及拉杆 伸缩机构的固定片、 连杆均不露出于铆枪座外面, 显得产品外观上比 较整齐干净。
进一步, 本发明的铆钉抓持机构的抓片座中设有抓片导槽, 抓片 嵌入抓片导槽中, 当拉铆枪操作时, 抓片在抓片座内腔中沿着抓片导 槽前后伸缩, 使抓片不易在抓片座中滑动, 提高了抓片的定向性、 稳 定性, 抓片也不会出现错位卡住现象。 同时增加了抓片与抓片座内腔 的接触面积使抓片在工作中不易损坏。 附图说明

下面结合附图和实施例, 对本发明的具体实施方式作进一步详细 描述。 以下实施例用于说明本发明, 但不用来限制本发明的范围。 实施例 1 :
如图 1至图 8所示: 一种双把式拉铆枪,包括铆枪座 6 (图 1、 5 ), 设置在所述的铆枪座 6前端的铆钉调节机构, 安装于所述的铆钉调节 机构内的铆钉抓持机构, 铆钉抓持机构固定在拉杆 8的前端, 一端通 过螺杆轴 5分别于所述的铆枪座 6的两侧与该铆枪座相铰接的两个把 手 9, 活动插设于所述的铆枪座 6的中心孔 12内的拉杆 8。 该拉杆 8 的全部和该拉杆末端上的拉杆伸缩机构之固定片 7及一端分别铰接该 固定片 7两侧、 另一端分别靠近所述螺杆轴 5旁铰接所述把手 9头部 的连杆 20均安设于所述的铆枪座 6腔体内,所述的拉杆 8的长度缩短; 所述固定片 7嵌设于所述的拉杆 8末端的固定槽 11中; 所述连杆 20 的一端通过第二销杆 19分别与所述的固定片 7的左右两侧铰接、另一 端通过第一销杆 21与所述把手 9头部相铰接,所述的把手 9头部设有 于与螺杆轴 5和第一销杆 21配合的孔;所述螺杆轴 5与所述第一销杆 21之间的距离小于或等于 9毫米; 所述的铆枪座 6两侧开有把手配合 槽 612 (图 1、 7 ); 所述把手 9的长度小于或等于 260毫米; 所述的第 一销杆 21在把手配合槽内其端部不超出把手配合槽 612。
所述铆枪座 6由前铆枪座 61和后铆枪座 62配合构成, 所述后铆 枪座 62前部的把手配合槽插入所述前铆枪座 61后部的把手配合槽中, 并有一连接件将所述前铆枪座 61和后铆枪座 62结合(图 5-8 )。
所述将前铆枪座 61和后铆枪座 62结合的连接件是所述螺杆轴 5, 所述螺杆轴 5将两个把手 9铰接于所述铆枪座 6两侧的把手配合槽 612 内, 且所述的第一销杆 21在铆枪座两侧的把手配合槽 612内。
所述的拉杆伸缩机构主要包括: 插设于所述的铆枪座 6的中心孔 12内的拉杆 8 , 前端通过所述螺杆轴 5分别于所述的铆枪座 6的两侧 与该铆枪座相铰接的两个把手 9, 嵌设于所述的拉杆 8末端固定槽 11 中的所述固定片 7, —端通过第二销杆 19分别与所述的固定片 7的左 右两侧连接、另一端通过第一销杆 21与所述的把手 9头部相铰接的所 述连杆 20。 所述的螺杆轴 5与所述第一销杆 21近距离而不碰着地平 行。 因销杆的头部都会是平的而不露出来, 所以销杆(包括第一销杆 21和第二销杆 19在铆枪座内不会有活动障碍 (销杆头部不会刮擦到 铆枪座内壁), 进而使第一销杆 21与螺杆轴 5能设置得更近(图 6、 只要连杆的头部不会碰着螺杆轴就可), 从而使拉铆枪的力臂增大,其 把手可相应缩短。
所述的拉杆末端固定槽 11底面是四个平面,每两个相邻的所述的 平面相互垂直;所述的固定槽 11的一对中嵌设有与之相适配且相互平 行的两个固定片 7, 两个固定片 7两侧的中间铰接着所述的连杆 20。 所述的拉杆 8末端的固定槽 11也可为圆环槽。
所述的铆钉抓持机构 (图 9-12 ) 主要包括: 抓片座 2、 设于所述 抓片座 2内腔的抓片 1、 抓片座 2中顶住抓片 1的顶杆 3和顶杆 3后 部的复位弹簧 4, 而抓片座 2内腔壁上还设有抓片导槽 22, 与抓片配 合的内腔为正六角锥形, 其六角锥形的角槽构成抓片导槽 22, 所述抓 片 1嵌入所述的抓片导槽 22中。 所述抓片 1可以为两瓣或三瓣抓片。
所述抓片座 2后部的内壁上设有与拉铆枪拉杆的头部相适配的螺 所述的铆枪座 6末端连接有集钉瓶 10。
所述的把手 9上可以开设有与各种规格的铆钉导嘴 15相适配的预 留铆钉导嘴放置孔 16, 所述的预留铆钉导嘴放置孔 16内放置有与之 相适配的预留铆钉导嘴 17。
所述的把手 9的末端套设有把手套 18。
本实施例由于拉杆长度缩短, 整个拉杆和拉杆伸缩机构的零部件 安设于所述的铆枪座腔体内, 这一结构使整把拉铆枪整齐干净, 而且 使整个拉铆枪体积进一步缩小, 使本产品小巧玲珑, 便于灵巧使用和 便于携带、 包装及运输。
本拉铆枪使用时, 首先, 将两个把手 9相分开, 此时, 拉杆 8在 连杆 7的带动作用下向前部运动, 导嘴将抓片顶开, 铆钉进入抓持机 构内。 因铆钉抓持机构固定在拉杆 8上, 所以铆钉抓持机构一起向前 运动; 合起把手 9时, 在顶杆和复位弹簧的作用下铆钉抓持机构抓住 铆钉向后运动并将铆钉拉断。 拉断后的铆钉通过拉杆 8的中心孔掉入 集钉瓶内。 由于拉杆 8和拉杆末端的拉杆伸缩机构的固定片及连杆均 安设于所述的铆枪座 6腔体内, 拉杆 8的前后运作均在铆枪座 6的中 心孔 12内,拉杆 8的前后运作就会十分稳定。 同时由于铆钉抓持机构 的抓片座 2中设有抓片导槽 22 , 所述抓片 1嵌入所述的抓片导槽 22 中, 使工作时抓片不易在抓片座中滑动, 使整个产品定向性、 稳定性 提高, 抓片也不会出现错位卡住现象。 拉杆和铆钉抓持机构的以上设 计使本发明的性能和工作效率大大提高。
实施例 2
另一种情况是: 有时需要拉铆枪前部的铆钉调节机构的调节座较 长的产品时, 操作中则需要拉杆较长地伸向铆钉, 此时拉杆 8的大部 及其后部, 和该拉杆末端的拉杆伸缩机构之固定片 7及一端分别铰接 该固定片 7两侧、 另一端分别靠近所述螺杆轴 5旁铰接所述把手 9头 部的连杆 20均安设于所述的铆枪座 6腔体内。拉杆仍需保持原有的长 度, 拉杆前部会仍然露出铆枪座, 其它结构与实施例 1相同。
但由于拉杆前部露出铆枪座的部分的外层有抓片座及调节座的掩 遮, 外部不能直接看到拉杆前部而不会使产品显得零乱。 而拉杆后部 却在铆枪座 6腔体内,因此拉杆的导向性、 稳定性仍会很好。 实施例 2 产品的体积仍然小于一般的拉铆枪。 虽然体积不如实施例 1能进一步 缩小, 但仍然具有实施例 1的其它优点。
另外, 本发明的实施例还可以做出一些改进和调整, 如实施例中 连杆 20与固定片 7铰接时,连杆设于两固定片之间,连杆的另一端由 销杆铰接于筐型的手柄的筐壁之中; 连杆也可设于固定片之上。 连杆 设于固定片之上时, 连杆的另一端则由销杆铰接于手柄之上。 但不管 怎么连接, 销杆的头部都会是平的而不露出来, 销杆的头部即不可能 与很大的螺杆轴的头部相抵触, 又不会刮擦到铆枪座内壁, 其目的是 销杆在铆枪座内不会有活动障碍进而使第一销杆与螺杆轴能设置得更 近, 进而使力臂增大。
以上所述仅是本发明的优选实施方式, 应当指出, 对于本技术领 域的普通技术人员来说, 在不脱离本发明技术原理的前提下, 还可以 做出若干改进和润饰, 这些改进和润饰也应视为本发明的保护范围。
