第一至九圖顯示本發明之外圓倒角修邊工具100的第一較佳實施例。首先，如第一圖所示，該外圓倒角修邊工具100主要包括一切削頭1以及插接至該切削頭1尾端的一轉接桿2。The first to ninth figures show a first preferred embodiment of the outer chamfering
如第二圖所示，該切削頭1具有一空圓錐體11、一體延伸自該空圓錐體11尾端的一柄部12，以及形成於該空圓錐體11內側的多個刀刃部13。其中，該空圓錐體11具有一內錐面111及一外錐面112。該柄部12的一端係一體連接該空圓椎體11的尾端，且另一端的端面軸向界定有一插接槽120（第三圖），供該轉接桿2插接。其中，該插接槽120係整個貫穿該柄部12並連通至該空圓錐體11之內部空間。As shown in the second figure, the
參閱第三至五圖，該切削頭1之空圓錐體11更於其周壁形成貫穿該內、外錐面111、112的多個排屑孔110。該些刀刃部13係分別緊鄰該些排屑孔110，且每一刀刃部13包括一主切削刃131與一副切削刃132。更詳而言之，如第四A圖所示，每一排屑孔110具有相對之一第一導斜面113及一第二導斜面114。該第一導斜面113鄰接該內錐面111之一第一區域111a且與該第一區域111a夾一鈍角，該第二導斜面114鄰接該內錐面111之一第二區域111b。值得注意的是，該第二區域111b被銑削形成一凹階14，該凹階14的一階面141與該第二導斜面114夾一銳角，且該凹階14的一階壁142鄰接該內錐面111之一第三區域111c。其中，該主切削刃131係形成於該第二導斜面114與該凹階14的階面141之間，而該副切削刃132係形成於該凹階14的階壁142與該內錐面111之第三區域111c之間。該主、副切削刃131、132之雙刀口設計使管件修邊的品質更臻完美。Referring to the third to fifth figures, the
在本較佳實施例中，該空圓錐體11具有四個排屑孔110，且每一排屑孔110於該空圓錐體11之內、外錐面111、112上分別具有長條形的一內開口110a及一外開口110b，如第六或七圖所示。每一排屑孔110係自該外開口110b朝著該空圓錐體11的一（順）時針方向側向傾斜至該內開口110a，以增加管件修邊的力道。然而，值得注意的是，如第六圖所示，該些排屑孔110之外開口110b的長軸之延伸方向交匯於該空圓錐體11之軸線，也就是說該些外開口110b並沒有採螺旋或朝著時針方向配置的設計。這樣的設計使得該空圓錐體11之該些排屑孔110較易於被精準加工製作出來。In the preferred embodiment, the
復參閱第二圖，該轉接桿2之兩端分別形成一第一接頭21及一第二接頭22，其中該第一接頭21係可拆離地卡合於該切削頭1之柄部12的插接槽120，而該第二接頭22係用以與一驅動工具（圖未顯示）相結合，例如電動/氣動/手動工具。在本實施例中，該轉接桿2之第二接頭22係一六角接頭，用以插接於該驅動工具之一套接孔。此外，呈六角形的該第二接頭22之周側形成有一定位環槽220，供該驅動工具卡扣固定。Referring back to the second figure, a
參閱第八圖，該切削頭1之柄部12的插接槽120由內而外包括一直筒段121及一多角段122，而該轉接桿2之第一接頭21包括相鄰的一圓柱段211及一角柱段212，分別對應卡合於該切削頭1之柄部12的插接槽120之直筒段121及多角段122。值得注意的是，該切削頭1之柄部12的插接槽120之直筒段121與該轉接桿2之第一接頭21的圓柱段211之間係採用靜配合（或稱精密配合），而該切削頭1之柄部12的插接槽120之多角段122與該轉接桿2之第一接頭21的角柱段212之間係採用餘隙配合。藉此，該轉接桿2一方面可被迫緊地插設於該切削頭1之柄部12的插接槽120內，且另一方面仍能有餘裕以方便該轉接桿2插拔於該插接槽120。Referring to the eighth figure, the
第八及九圖係顯示本發明外圓倒角修邊工具100對一工件（例如：管件或螺桿）進行倒角修邊作業的前、後示意圖。如圖所示，經過前進並轉動的切削過程後，該外圓倒角修邊工具100可於該工件3的端緣上形成一外圓倒角31。此外，由於該切削頭1之空圓椎體11呈類似喇叭狀，故可接收不同口徑的工件。Figures 8 and 9 are schematic diagrams showing the front and rear sides of the chamfering and trimming
第十及十一圖顯示本發明之外圓倒角修邊工具200的第二較佳實施例，在此實施例中的切削頭1結構及功能與前述第一較佳實施例中的切削頭1完全相同，兩實施例之差別在於該轉接桿2a之第二接頭22a係一SDS規格之四溝接頭，用以插接於一驅動工具（圖未顯示）之套接孔。Figures 10 and 11 show a second preferred embodiment of the outer chamfering
第十二及十三圖顯示本發明之外圓倒角修邊工具300的第三較佳實施例，在此實施例中的切削頭1a結構及功能與前述第一較佳實施例中的切削頭1大致相同，差別在於該切削頭1a之柄部12a於其周壁界定有一定位卡槽123，連通該插接槽120，而該轉接桿2之第一接頭21更具有一定位珠213，其受一內部的彈簧214之頂抵而彈性地凸伸於該角柱段212的一側邊，以在該轉接桿2b之第一接頭21a卡合於該切削頭1a之柄部12a的插接槽120時，對應地卡入該切削頭1a之柄部12a的定位卡槽123內，如第十三圖所示。如此，該轉接桿2b可以更加牢固地插設於該切削頭1a之柄部12a的插接槽120，增加使用壽命。Figures 12 and 13 show a third preferred embodiment of the outer chamfering
第十四及十五圖顯示本發明之外圓倒角修邊工具400的第四較佳實施例，在此實施例中的切削頭1b結構及功能與前述第三較佳實施例中的切削頭1a大致相同，兩實施例之差別在於該轉接桿2c不具有圓柱段，而完全被角柱段212所取代。因此，在本實施例中，該切削頭1b之柄部12b的插接槽120a之斷面完全呈多角形，而該轉接桿2c之第一接頭21b完全係一多角柱體，對應卡合於該切削頭1b之柄部12b的插接槽120a內。此外，該切削頭1b之柄部12b於其周壁界定有一定位卡槽123，連通該插接槽120a，而該轉接桿2c之第一接頭21b更具有一定位珠213，其受一內部的彈簧214之頂抵而彈性地凸伸於該多角柱體的一側邊，以在該轉接桿2c之第一接頭21b卡合於該切削頭1b之柄部12b的插接槽120a時，對應地卡入該切削頭1b之柄部12b的定位卡槽123內，如第十五圖所示。Figs. 14 and 15 show the fourth preferred embodiment of the outer chamfering
藉由上述設置，本發明之外圓倒角修邊工具利用雙刀口設計使管件修邊的品質更臻完美。再者，本發明之外圓倒角修邊工具採用易於加工的排屑孔110，但仍能維持良好的切削能力。此外，本發明之外圓倒角修邊工具因其配件具有可拆離的特性，故其切削頭可根據電動/氣動/手動工具之需要而選擇搭配適合的轉接桿，以對管件或柱體進行外圓倒角修邊作業，而不會受限於特定之電動/氣動/手動工具。With the above-mentioned settings, the outer chamfering edge trimming tool of the present invention utilizes the double-knife design to perfect the quality of the edge trimming of the pipe fittings. Furthermore, the round chamfering edge trimming tool of the present invention uses an easy-to-machine
