的在於提供-種免除工件翻轉、避紋位誤差而增進加工 效率及加工品質的上下倒角刀具。 根據上述之目的，本新型之一態樣是在提供一種上下 ㈣刀具’用以切削-工件的周緣’以形成—倒角；該上 下倒角刀具包含：一圓形刀盤；至少一刀台，等間距地設 於圓形刀盤的外周，刀台具有一内側面及一與該内側面相 接續的前錐部，該前錐部具有相交的一上斜面與一下斜面 ^以及至少一切削體，其具有一前切削錐部，該前切削錐 部具有相交的一上切削斜面與一下切削斜面，切削體設於 4 M443594 的下切削斜面233切削工件300的頂面周緣，而在該頂面 周緣處切削形成一上倒角310(如第5圖所示）；之後，機 器移動其轉動件260使得圓形刀盤21〇位於工件3〇〇的下 方，同樣地，圓形刀盤210被轉動件260帶動旋轉，並沿 著工件300的頂面周緣移動，上下倒角刀具2〇〇乃以其突 出的上切削斜面232切削工件300的底面周緣，而在該底 面周緣處切削形成一下倒角320(如第6圖所示）。 如此，依據本新型第一實施例之上下倒角刀具，在不 需翻轉工件3〇〇的情況下，即可分別對工件的頂面周緣及 底面周緣切削加工而分別形成上倒角31〇及下倒角32〇。 其省卻了工件300翻轉及重新定位的時間，並避免重新定 位所可能產生的誤差，因而增進加工效率及品質；而且依 據本新型第-實施例之上下㈣刀具，係以下切削斜面 233及上切削斜面232分別對工件期切削形成上倒角 310及下倒肖320，減少以同一切削斜面同時用來切削形 鲁成上倒角及下倒角的使用頻率，因而相對地可增加本新型 上下倒角刀具200的使用壽命。 第7圖是緣示依照本新型一第二實施例之上下倒角 刀具並結合於一轉動件的側視圖。在該第二實施例當中， 係以兩個相同的上下倒角刀具上下叠設於轉動件 260 ’其兩者倒角刀具2〇〇之彼此切削體23〇之間的間距 即為工件30G的厚度。依據該第二實施例之上下倒角刀 具’以-次的切削加工，即可利用位於上方之倒角刀且 200的下切削斜δ 233及位於下方之倒角刀具的上^刀 7 M443594 第1圖是緣示一習知倒角刀具的剖視示意圖。 、第2圖是緣示依照本新型一第—實施例之上下倒角刀 具並結合於一轉動件的仰視立體圖。 第3圖是緣示第2圖所示上下倒角刀具的側視圖。 第4圖是緣示第2圖所示上下倒角刀具的仰視圖。 第5圖是繪示第4圖所示上下倒角刀具的使用示意圖 ，顯示依該倒角刀具的下切削斜面對—讀切削形成上倒 角的使用狀況。 • 帛6圖是繪示第頓所示上下倒角刀具的另一使用示 意圖，顯示依該倒角刀具的上切削斜面對一工件切削形成 下倒角的使用狀況。 、第7圖是繪示依照本新型一第二實施例之上下倒角刀 具並結合於一轉動件的侧視圖。 、第8圖是繪示依照本新型一第三實施例之上下倒角刀 具並結合於一轉動件的側視圖。 • 第9圖是繪示第8圖所示上下倒角刀具的仰視圖。 【主要元件符號說明】 100 : :習知倒角刀具 111 : 刀台 120 : 切削體 130 : 轉動件 210 : 圓形刀盤 220 : 刀台 110 ： 刀座 112 ： 下斜面 121 ： 下切削斜面 200 ： 本新型下倒角刀具 211 ： 刀槽 221 ： 内側面 9 M443594 222 ： 224 : 231 ： 233 ： 250 : 300 : 320 : 前錐部 下斜面 前切削錐部 下切削斜面 螺栓 工件 下倒角 223 :上斜面 230 :切削體 232 :上切削斜面 240 :刀襯 260 :轉動件 310 :倒角（上倒角）It is to provide a top and bottom chamfering tool that eliminates workpiece turning and avoids streaking errors and improves machining efficiency and machining quality. According to the above object, one aspect of the present invention provides an upper and lower (four) cutter 'for cutting - the circumference of the workpiece' to form a chamfer; the upper and lower chamfering tool comprises: a circular cutter head; at least one cutter table, Equally spaced on the outer circumference of the circular cutter head, the cutter table has an inner side surface and a front taper portion continuous with the inner side surface, the front taper portion having an upper inclined surface and a lower inclined surface and at least one cutting body. The front cutting cone has an upper cutting bevel and a lower cutting bevel, and the cutting body is disposed on the lower cutting bead 233 of 4 M443594 to cut the periphery of the top surface of the workpiece 300, and at the periphery of the top surface The cutting forms an upper chamfer 310 (as shown in Fig. 5); after that, the machine moves its rotating member 260 such that the circular cutter head 21 is positioned below the workpiece 3〇〇, and likewise, the circular cutter 210 is rotated. The piece 260 rotates and moves along the periphery of the top surface of the workpiece 300. The upper and lower chamfering tools 2 are cut by the upper cutting bevel 232 of the workpiece to cut the periphery of the bottom surface of the workpiece 300, and the chamfer is cut at the periphery of the bottom surface. 320 ( Shown in FIG. 6). In this way, according to the upper chamfering tool of the first embodiment of the present invention, the top chamfer 31 and the bottom periphery of the workpiece can be separately cut without cutting the workpiece 3〇〇, respectively. Lower chamfer 32〇. The utility model saves the time for the workpiece 300 to be reversed and repositioned, and avoids the error which may be generated by repositioning, thereby improving the processing efficiency and quality. Moreover, according to the fourth embodiment of the present invention, the following cutting bevel 233 and the upper cutting are performed. The inclined surface 232 respectively forms the upper chamfering 310 and the lower chamfering 320 on the workpiece period, and reduces the use frequency of the same cutting bevel surface for cutting the upper chamfering and the lower chamfering at the same time, thereby relatively increasing the novel up and down The service life of the angle cutter 200. Fig. 7 is a side elevational view showing the upper chamfering cutter in accordance with a second embodiment of the present invention and coupled to a rotating member. In the second embodiment, two identical upper and lower chamfering tools are stacked on top of each other on the rotating member 260', and the distance between the two chamfering tools 2's cutting bodies 23〇 is the workpiece 30G. thickness. According to the second embodiment, the lower chamfering tool 'in the next cutting process can use the chamfering knife located above and the lower cutting inclination δ 233 of 200 and the upper chamfering tool of the chamfering tool 7 M443594 1 is a cross-sectional view showing a conventional chamfering cutter.
