Description

一种打钉机 技术领域
本实用新型属于机械制造技术领域，涉及一种打钉装置，具体是一种打钉机。
背景技术
打钉机即钉枪，包括电动钉枪，气动钉枪，瓦斯钉枪，手动钉枪等。气动钉枪也叫气动打钉机,现有的气动打钉机大多以气泵产生气压推动撞针作为电机,高压气体带动打钉机气缸里的撞针做锤击运动,将排钉夹中的排钉钉入物体中或者将排钉射出去。通常打钉枪枪身部装由枪体、气缸、平衡阀、开关组件、撞针组件、缓冲垫、枪嘴、枪槽等组成，利用压缩空气与大气压差，通过扳机开关使撞针在气缸内做往复运动；打钉机弹夹部装是由枪头、枪盖、固定弹夹、活动弹夹等配件组成，通过压簧或拉簧将钉送到枪盖槽内，当撞针从枪嘴出来时，将钉打出。
我国专利(公告号：CN204019481U；公开日：2014-12-17)公开了一种气动打钉装置，包括送钉系统、盖板、盖板螺钉、压块、压块螺钉、撞针，送钉系统的上端设置有过钉通道，撞针设置在过钉通道内，盖板和压块设于过钉通道上方，撞针可以在过钉通道内移动，盖板上设置有通孔，送钉系统的上端设置有盖板螺钉螺纹孔，通孔内设置有盖板螺钉，盖板螺钉穿过通孔，并旋紧于盖板螺钉螺纹孔，盖板上设置有磁铁孔，磁铁孔内设置有磁铁。
上述专利中没有公开具体的送钉系统结构，而采用现有技术中的气泵产生气压推动撞针作为电机，在结构上比较笨重，而且不能保证击发撞针的连续高效性。
发明内容
本实用新型针对现有的技术存在的上述问题，提供了一种打钉机，本实用新型所要解决的技术问题是：如何降低打钉机的体积和重量并保证打钉机能够连续高效击发。
为了解决上述技术问题，本实用新型的技术方案如下：
一种打钉机，其特征在于，所述打钉机包括封闭的缸体一和设置在缸体一外封闭的缸体二，所述缸体一的工作腔和所述缸体二的工作腔相互连通，所述缸体一内具有活塞一且活塞一上固连有撞针，所述撞针上具有限位部，所述打钉机还包括卡接件，所述缸体二内设有活塞二且活塞二由电机带动在所述缸体二的第一位置和第二位置之间往复移动；在活塞二处于第一位置时，所述活塞一向内移动后由所述卡接件卡接在撞针的限位部上，在活塞二处于第二位置时，所述电机带动所述卡接件脱离所述限位部。
其原理是：本打钉机通过电机带动活塞二在缸体二内往复移动，活塞二能够到达第一位置和第二位置两个极限点，活塞二到达第一位置时，缸体二内产生负压，由于缸体一与缸体二相连通，会对活塞一产生吸附，使活塞一向内移动，撞针也随之向缸体一内收缩，活塞一达到极限位置后，卡接件与撞针的限位部相卡接，限制撞针的移动，然后，电机带动活塞二进行下一个行程，活塞二向第二位置移动，缸体一和缸体二内产生高压气体，由于活塞一以及撞针受到卡接件和限位部的卡接限位，活塞一和撞针保持不动，当活塞二到达第二位置后，电机继续工作，触发卡接件，使得卡接件脱离限位部，在高压气体的推动下，撞针随着活塞一迅速有力的发射。打钉机通常还与能够放置钉子的弹夹部配合使用，弹夹内放置排钉，并且排钉的第一个钉子能够与撞针相对，通过撞针的撞击，将钉子打出钉入物体中或者将钉子射出去。本打钉机不需要额外的气压泵，只需要通电即可，减少了占用空间。
本技术方案中通过电机带动活塞二压缩空气，并通过该电机带动卡接件，实现排钉的快速连续击发。
在上述的打钉机中，所述电机为直流电机，所述直流电机的输出轴上固连有能够绕该输出轴轴线周向转动的铰接杆，所述铰接杆上枢接有与所述活塞二相连的连杆。该连杆一端枢接在铰接杆上，另一端铰接在活塞二上。作为替换方案，该连杆一端枢接在铰接杆上，另一端通过万向球连接在活塞二上。
在上述的打钉机中，所述打钉机还包括壳体，所述缸体一和缸体二并排设置在壳体上，所述缸体一的尾端开设有通孔一，所述缸体二的尾端开设有通孔二，所述通孔一与通孔二通过通孔三相连通。这样的设计能够保证打钉枪的结构紧凑，通孔三的通道中可以储存压缩空气。
在上述的打钉机中，所述卡接件通过枢轴一连接在所述壳体上，所述壳体上还设有枢轴二，所述枢轴一上固连有连接板一，所述枢轴二上固连有拨块，所述拨块与所述连接板一之间设有连接板二，所述连接板二的两端分别与所述拨块与连接板一相铰接；所述拨块能够与所述铰接杆相抵靠。铰接杆在电机的带动下转动，每转动一周就能够触发拨块一次，拨块通过连接板二带动连接板一转动，再带动枢轴一转动，从而带动与枢轴一相连的卡接件动作，实现触发。
在上述的打钉机中，所述撞针为长条形的板体，所述限位部为开设在所述撞针侧壁上的凹槽。卡接件抵靠在凹槽上，使得撞针不能在缸体一内向前移动，结构简单，加工方便。
在上述的打钉机中，所述凹槽的槽壁包括一段抵靠面和一段弧面，所述抵靠面为平面且垂直于所述撞针的长度方向，所述弧面从撞针的侧壁延伸至所述抵靠面。在撞针的移动过程中，卡接件沿撞针的侧壁滑动，并最终抵靠在该抵靠面上，在电机作用下又能使卡接件脱离该抵靠面，抵靠面为平面且垂直于撞针的长度 方向，这样能够保证抵靠卡接时的稳定性，也能便于卡接件的脱离。
在上述的打钉机中，所述卡接件上连接有能够使所述卡接件的端部抵靠在撞针侧壁上的扭簧。扭簧能够保证卡接件抵靠在限位部里实现限位作用。
与现有技术相比，本实用新型具有以下优点：
1、本打钉机中通过电机带动活塞二压缩空气，并通过该电机触动卡接件，实现排钉的快速连续击发，结构紧凑，稳定可靠。
2、本打钉机中通过一个电机既能够压缩空气，也能够实现撞针的自动击发，自动化程度高。

打钉机通常还与能够放置钉子的弹夹部配合使用，弹夹内放置排钉，并且排钉的第一个钉子能够与撞针6相对，通过撞针6的撞击，将钉子打出钉入物体中或者将钉子射出去，由于采用一个电机7既压缩空气，又触发卡接件9，有序的结合从而实现排钉的快速连续击发。
如图2和图4所示，卡接件9通过枢轴一16连接在壳体1上，壳体1上还设有枢轴二17，枢轴一16上固连有连接板一18，枢轴二17上固连有拨块20，拨块20与连接板一18之间设有连接板二19，连接板二19的两端分别与拨块20与连接板一18相铰接；拨块20能够与铰接杆14相抵靠，铰接杆14在直流电机的带动下转动，每转动一周就能够触发拨块20一次，拨块20通过连接板二19带动连接板一18转动，再带动枢轴一16转动，从而带动与枢轴一16相连的卡接件9动作，实现触发。
如图2、图3、图5和图6所示，撞针6为长条形的板体，限位部8为开设在撞针6侧壁上的凹槽81，凹槽81的槽壁由抵靠面811和弧面812组成，抵靠面811垂直于撞针6的长度方向，弧面812从撞针6的侧壁延伸至抵靠面811；卡接件9能够抵靠在抵靠面811上，使得撞针6不能在缸体一2内向前移动；卡接件9上还连接有能够使卡接件9的端部抵靠在撞针6侧壁上的扭簧，能够保证卡接件9抵靠在限位部8里实现限位作用。
本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了1、壳体；2、缸体一；3、缸体二；4、活塞一；5、活塞二；6、撞针；7、电机；8、限位部；81、凹槽；811、抵靠面；812、弧面；9、卡接件；11、通孔一；12、通孔二；13、通孔三；14、铰接杆；15、连杆；16、枢轴一；17、枢轴二；18、连接板一；19、连接板二；20、拨块等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本实用新型的本质；把它们解释成任何一种附加的限制都是与本实用新型精神相违背的。
