Description

气动打钉枪的送钉弹匝
本发明所属技术领域
本实用新型涉及气动工具的打钉枪， 特别是气动打钉枪的送钉弹匣。
在本发明之前的现有技术
现有公开各种 P630打钉枪钉槽送钉结构， 由于所打排钉高度有 12、 15、 18、
22、 25、 30六个品种之多， 在打钉时， 撞钉在每次打钉完成后， 作回返运动时， 由于摩擦力的作用， 往往容易把后续之钉往回拖动， 卡入枪嘴过钉槽， 形成卡钉， 影响作业； 因此现有的打钉枪均在弹匣中设置一游动调整尺作挡钉功能， 随所放 置排钉的高度， 移动调整尺， 阻挡后续之钉回拖并完成连续打钉作业； 另， 在送 钉、 打钉过程中， 由于排钉高度不同， 推钉块因为调整尺挡钉功能所战友空间的 限制， 不能过高 （超过 12.5mm)， 在打 22 以上排钉时， 排钉在推送过程中， 排 钉只是前端受力， 出现前高后低倾斜的现象， 使撞钉无法撞击到排钉后端或只撞 击到一部分， 出现咬钉或打空钉现象， 影响作业； 在公开的 630打钉枪钉槽送钉 结构中， 亦出现有自动调置挡钉位和辅助推钉之结构， 但因送钉结构放置于弹匣 盒中， 弹匣在置入不是连排的散钉时， 排钉在推钉块的推力下容易出现前、 后排 钉错位相咬现象， 使排钉不能顺畅送出， 影响打钉效率， 且排钉放置于弹匣中， 无法观察排钉之运动， 在打钉作业时， 作业者无法知道排钉是否打完， 容易失手 造成伤害。
本发明的目的
本实用新型的目的是提供一种可自动感应排钉位置， 进行自动调节挡钉、 自 动设置压钉机关， 且无前后排钉错位等咬钉现象、 使作业者可直接观察送钉运动 情况的气动打钉枪的送钉弹匣。
本发明的技术方案
本实用新型固接于主机体与手把上， 送钉弹匣上分布有钉槽主体、 推钉器、 钉槽主体压板等， 钉槽主体上设有多条平行分布的通槽， 钉槽主体右端接有与之 垂直的枪嘴和枪嘴面板， 使其能与主机体相连， 而排钉可通过枪嘴送出；
钉槽主体后侧与推钉器相连， 推钉器侧端上开有与钉槽主体上通槽相对应的 凹槽， 凹槽上放置的推钉块可穿入通槽内， 并在推钉器的带动下， 贴近钉槽来回 运动， 推钉块的末端有弹簧定位； 钉槽主体压板由弹簧片将其上沟槽内的压钉块卡合于钉槽主体前端通槽上； 钉槽主体顶端的枪嘴上开有与通槽相对应的槽， 使推钉块、 压钉块穿入并实 现自动感应挡钉功能。
采用上述技术方案由于钉槽主体上分布的通槽均是以排钉高度设置， 适合不 同型号排钉的放置， 通槽后部之推钉器上设置的推钉块与前部钉槽主体压板上设 置的压钉块相互卡合， 压钉块与推钉块可自动感应排钉高度， 并调节挡钉位置， 当使用 22mm高度以上排钉时， 有两块以上推钉块同步推钉， 使排钉在运动中受 力均匀， 不会倾斜， 避免出现打空钉和夹钉现象； 压钉块可将排钉紧紧贴合于钉 槽上， 避免在装入不成排的散钉或因排钉被震散后所出现前后排错位之咬钉的现 象； 本实用新型将推钉器放置于钉槽主体的后部， 使作业者可从外直接观察排钉 在弹匣中的运动情况， 增加了安全感， 也解决了现有气动打钉枪在使用 22mm高 度排钉时， 较易出现空钉、 卡钉等问题。
