Description

膠槍驅動裝置
本發明係有關於一種膠槍驅動裝置。
按，一般膠槍係用於工業或居家施工之填縫、接補等作業時使用，習知膠槍結構具有扳扣組件及推桿，利用按壓扳扣組件之方式，該扳扣組件即可帶動推桿滑動，以將膠體擠出，然而此使用方式過於費力，市面上便研發了一種電動驅動之膠槍，藉由馬達轉動以帶動滾珠螺桿滑移，以將膠體擠出，專利號TWI551031所揭露之膠槍驅動裝置即屬此類，習知電動膠槍使用完畢後，需要將螺桿退回至原點，以將空的膠管退出，習知退桿方式係控制馬達之電路系統使馬達反轉，以將螺桿退回至原點。
然而，由於習知電動膠槍之退桿方式係控制馬達之電路系統使馬達反轉，如此會使退桿時間過長而延誤作業時間，另外會使習知電動膠槍之電路系統的成本提高，且容易有故障之可能，而存在亟待改善之缺弊。
因此，有必要提供一種新穎且具有進步性之膠槍驅動裝置，以解決上述之問題。
本發明之主要目的在於提供一種膠槍驅動裝置，可利用馬達轉動帶動螺桿滑移以將膠體平穩地自膠管內擠出，且該膠槍驅動裝置具有離合裝置，可快速地將螺桿往復滑移，以達到快速拆裝膠管之功能。
為達成上述目的，本發明提供一種膠槍驅動裝置，其包括一殼體、一驅動組件、一螺桿、一傳動組件及一離合裝置。該殼體定義一軸向。該驅動組件設於該殼體，包括一馬達組件及一驅動齒輪，該馬達組件與該驅動齒輪係為轉動連結關係。該螺桿滑設於該殼體且不可相對該殼體轉動，該螺桿設有一螺旋溝槽。該傳動組件設於該殼體內，包括一傳動套及複數卡抵件，該傳動套係套設於該螺桿並徑向穿設有複數穿孔，該等卡抵件係分別容置於該等穿孔，該傳動套與該驅動齒輪為轉動連結。該離合裝置包括一限位組件及一制動件，該限位組件套設於該傳動套，該制動件可相對該殼體移動於一第一位置及一第二位置。其中，當該制動件位於該第一位置時，該制動件係徑向抵頂於該限位組件，該限位組件即將該等卡抵件限位抵頂於該螺旋溝槽，該螺桿即無法相對該傳動套沿該軸向滑移；當該制動件位於該第二位置時，該制動件係不徑向抵頂於該限位組件，該等卡抵件不受到該限位組件之限制而可選擇性地脫離該螺旋溝槽，該螺桿即可相對該傳動套沿該軸向滑移。
以下僅以實施例說明本發明可能之實施態樣，然並非用以限制本發明所欲保護之範疇，合先敘明。
請參考圖1至圖5，其顯示本發明之一較佳實施例，本發明之膠槍驅動裝置包括一殼體1、一驅動組件2、一螺桿3、一傳動組件4及一離合裝置5。
該殼體1定義一軸向11。
該驅動組件2設於該殼體1，包括一馬達組件21及一驅動齒輪22，該馬達組件21與該驅動齒輪22係為轉動連結關係。
該螺桿3滑設於該殼體1且不可相對該殼體1轉動，該螺桿3設有一螺旋溝槽31。於本實施例中該殼體1設有一防轉件12，該防轉件12具有一插孔121，該插孔121具有一平面段122，該螺桿3穿設於該插孔121並設有一對應該平面段122之凹陷段32，藉此該螺桿3即不可相對該殼體1轉動。
該傳動組件4設於該殼體1內，包括一傳動套41及複數卡抵件42，該傳動套41係套設於該螺桿3並徑向穿設有複數穿孔411，該等卡抵件42係分別容置於該等穿孔411，該傳動套41與該驅動齒輪22為轉動連結，當該馬達組件21帶動該驅動齒輪22轉動時，該驅動齒輪22即會帶動該傳動套41轉動。於本實施例中各該卡抵件42係為滾珠，各該卡抵件42滑設於該穿孔411。
該離合裝置5包括一限位組件51及一制動件52，該限位組件51套設於該傳動套41，該制動件52可相對該殼體1移動於一第一位置及一第二位置。於本實施例中該傳動套41遠離該制動件52之一端設有一外螺紋段413，該驅動齒輪22設有一內螺紋段221，該驅動齒輪22係套設於該傳動套41且該內螺紋段221係與該外螺紋段413相螺接，該驅動齒輪22及可帶動該傳動套41轉動，且可防止該驅動齒輪22與該傳動套41相互滑移。
其中，當該制動件52位於該第一位置時，該制動件52係徑向抵頂於該限位組件51，該限位組件51即將該等卡抵件42限位抵頂於該螺旋溝槽31，該螺桿3即無法相對該傳動套41沿該軸向11滑移，另外當該傳動套41被該驅動齒輪22帶動轉動時，由於該螺桿3無法相對該殼體1轉動，容置於該等穿孔411之該等卡抵件42在隨著該傳動套41轉動時即會帶動該螺桿3相對該殼體1沿該軸向11滑動；當該制動件52位於該第二位置時，該制動件52係不徑向抵頂於該限位組件51，該等卡抵件42不受到該限位組件51之限制而可選擇性地脫離該螺旋溝槽31，當使用者握持該螺桿3並欲帶動該螺桿3滑動時，該等卡抵件42會受到該螺旋溝槽31之推擠而徑向朝外跳脫，該螺桿3即可相對該傳動套41沿該軸向11滑移，以達到快速拆裝膠管（未繪示）之功能。
具體而言，該制動件52係套設於該傳動套41並可相對該傳動套41沿該軸向11滑動，該制動件52包括一環壁521，當該制動件52位於該第一位置時（如圖4所示），該環壁521係套束於該限位組件51，該限位組件51即無法徑向朝外擺動，該限位組件51即會穩固地將該等卡抵件42抵頂於該螺旋溝槽31，當該制動件52朝該第二位置移動時（如圖5所示），該制動件52係朝遠離該限位組件51之方向移動且該環壁521係脫離該限位組件51，該限位組件51即不受到該環壁521之套束而可徑向朝外擺動。
進一步地說，該限位組件51包括至少二夾持片511及一彈性扣件512，該至少二夾持片511圍構呈圓筒狀，該彈性扣件512套設於該至少二夾持片511，以常態地將該至少二夾持片511朝該傳動套41徑向抵頂，於本實施例中該限位組件51包括四該夾持片511且該等夾持片511係未相互連結，其中當該制動件52位於該第一位置時，該環壁521係套束於該等夾持片511，該等夾持片511即無法徑向朝外擺動；當該制動件52位於該第二位置時，該至少二夾持片511即脫離該環壁521之束縛，當該螺桿3欲滑動時，該等卡抵件42會受到該螺旋溝槽31之推擠而徑向朝外跳脫，該等卡抵件42即會將該等夾持片511徑向朝外抵頂，並掙脫該彈性扣件512之拘束，使該彈性扣件512彈性變形，該等卡抵件42即可順利跳脫該螺旋溝槽31，該螺桿3即可順利地相對該傳動套41沿該軸向11滑移，要說明的是，於本實施例中該等夾持片511係未相互連結，於其它實施例中該等夾持片511之一端可相互連接而形成一套筒狀，該等夾持片511之另一端係為可樞擺之自由段亦無不可。
較佳地，該傳動套41沿周向設有至少二凸緣412，各該夾持片511設有一凹槽513，該等凸緣412係分別卡抵於一該凹槽513，以使各該夾持片511無法相對該傳動套41沿該軸向11移動，以免當該螺桿3相對該殼體1滑動時帶動該等夾持片511滑動，於其它實施例中該等凹槽513與該等凸緣412為相反設置亦無不可，不以此為限。
於本實施例中該環壁521係朝該限位組件51之方向漸擴，該限位組件51朝向該環壁521之一端設有一漸縮段514，當該制動件52位於該第一位置時，該環壁521係套束於該漸縮段514，可避免該環壁521之端面與該漸縮段514之端面相互抵頂而無法順利套束。
詳細的說，於本實施例中該離合裝置5另包括一彈性件53及一撥桿54，該彈性件53係彈抵設於該殼體1與該制動件52之間，以使該制動件52具有朝該第一位置移動之趨勢，該撥桿54樞設於該殼體1且一端係卡抵於該制動件52，藉由按壓該撥桿54遠離該制動件52之一端以將該制動件52移動至該第二位置，因此於操作時，使用者僅需一手按壓該撥桿54將該制動件52移動至該第二位置，另一手握持該螺桿3，即可將該螺桿3快速滑移。
綜上，本發明之膠槍驅動裝置，當該制動件位於該第二位置時，該制動件係不徑向抵頂於該限位組件，該等卡抵件不受到該限位組件之限制而可選擇性地脫離該螺旋溝槽，當使用者握持該螺桿並欲帶動該螺桿滑動時，該等卡抵件會受到該螺旋溝槽之推擠而徑向朝外跳脫，該螺桿即可相對該傳動套沿該軸向滑移，以達到快速拆裝膠管之功能。
