portion, the support surface becomes, or the like to correspond to the inclined surface 38 of the screw or other fastener in combination. 螺紋件38的扩大的夹头可具有任何方便的形状,如锥形,球形,或另外的形式,以对应钻头保持件12和插件35的类似表面。 Expanding collet threaded member 38 may have any convenient shape, such as conical, spherical, or another form, similar to a corresponding drill holder member 12 and the surface 35 of the plug. 在典型形式中,通过偏置孔36和70的轴线,当用螺紋件38固定插件35到槽30时,将使插件35向下靠到底表面32。 In a typical form, through the biased aperture 36 and axis 70, when 35 to 30 when the plug 38 is fixed with a screw groove, will in the end plug 35 downwardly against the surface 32. 钻头插件35还包括插件35宽度方向的刃脊或侧面80,各侧面80包括螺旋延伸的边缘82,和径向向内定位的间隙表面84。 35 further comprises an insert plug drill 35 in the width direction of the side edges or ridges 80, each side 80 comprises a helical edge 82 extending radially inwardly and positioned clearance surface 84. 边缘表面82是圆柱形,围绕插件35的旋转轴线18形成,并可接触钻出孔的边缘。 Edge surface 82 is cylindrical, formed around the axis of rotation 18 of the plug 35, and the contact edge of the drilled hole. 但是,与现有技术的扁钻插件不同,边缘82的尾侧是螺旋的,其中边缘宽度从扁钻插件35的一个侧面上的切削刃到扁钻插件35的相对侧面螺旋增加,如图3C所示。 However, the prior art plug with a flat drilling different, the trailing side edge 82 of the spiral, wherein the width of the flat edge of the drill plug on one side of the cutting edge 35 to the opposite flat sides of the drill plug screw 35 increases, as shown in FIG 3C Fig. 螺旋边缘82导致侧面80的几乎全部径向宽度能够接触孔,如图3B的顶视图所清楚显示。 Spiral side edges 82 cause almost all of the radial width of the contact hole can be, 3B a top view of FIG 80 clearly shown. 因此, 螺旋延伸的边缘82提高了工具组件10操作时的稳定性,防止发出更多声响。 Thus, the helically extending edge 82 increases the stability during operation of tool assembly 10, to prevent sound emitted more. 尽管第一实施例的扁钻组件可提供更高的稳定性,但因为边缘产生摩擦,更多的表面区与孔接触可导致热量增加,这可能不适合某些用途。 While flat drilling assembly according to the first embodiment can provide greater stability, but because the edge of the friction, the more surface area in contact with the bore can cause increased heat, which may not be suitable for certain applications. 现在参考图4A到4E,显示了本发明的第二实施例的扁钻插件35、,其包括平行的螺旋边缘82、,其中边缘的前侧也是螺旋的。 Referring now to FIGS. 4A to 4E, it shows a second embodiment of flat drill insert of the present invention comprising 35 ,, 82 ,, parallel helical edge which is the front edge of the spiral. 平行的螺旋边缘82、与第一实施例的不同之处在于,设置了螺旋释放槽86 , 使得边缘宽度从插件35、的一侧的切削刃保持到插件35、的另一侧的后位,如图4C清楚显示。 Helical edge 82 parallel to the first embodiment is different from the embodiment in that a spiral groove 86 is released, so that the width of the edge from the cutting edge side of the retaining plug 35, the plug 35 to the rear position of the other side, 4C clearly shown in FIG. 添加的螺旋释放槽86减少了插件35、和孔之间的接触区,这样就减少了插件35、和孔之间的摩擦,从而降低了搡作温度并允许有更高的速度(SFM)或钻进速率,并可增加工具寿命。 Add helical groove 86 reduces the release of 35, and the contact area between the plug hole, thus reducing the friction between the 35 and the plug hole, thereby lowering the temperature for shoving and allow higher speeds (SFM) or drilling rate, and increase tool life. 平行的螺旋边缘82、还导致侧面80、的几乎全部径向宽度能够接触孔, 如图4B的顶视图清楚显示。 Parallel spiral edges 82, 80 also causes the side, almost all of the radial width of the contact hole can be top view clearly shown in FIG 4B. 因此,钻头插件35、提供了比现有技术扁钻插件更好的稳定性。 Thus, the plug drill 35 is provided over the prior art flat plug drill better stability. 此外,边缘宽度可比现有技术的减少,这样可减少插件的侧面80、产生的热量,可进一步增加工具的寿命和/或允许工具以更高速度操作,同时保持工具的寿命。 In addition, reducing the width of the edge than the prior art, this reduces side plug 80, the heat generated can be further increased tool life and / or allow the tool to operate at a higher speed while maintaining tool life. 现在参考图5A到5E,本发明的第三实施例的扁钻插件35、、包括平行的螺旋边缘82、、,其具有边缘82、、附近的螺旋开槽或凹槽88。 Referring now to FIGS. 5A to 5E, flat third embodiment of the present invention comprises a drill plug 35 ,, 82 ,,, edges parallel to the helical edge 82 ,, having a helical groove or slot 88 near. 开槽88可帮助槽中的钻屑离开孔,并可帮助钻屑形成。 Slot 88 can help cuttings slot exit aperture, and help cuttings formed. 此外,开槽88 可防止钻屑保留在螺旋边缘的前边,这可能发生在某些用第二实施例的插件35、、进行加工的场合。 In addition, the cuttings retained prevented slot 88 in the front edge of the spiral, which may occur in the case of the second embodiment of the plug with some 35 ,, for processing. 设置开槽88不防碍平行的螺旋边缘82、' 在侧面8(T的几乎整个径向宽度上接触孔,如图5B的顶视图所示。 这使得插件35'、可保持前面实施例提供的高稳定性。开槽88位于从孔70径向向外的地方,使得标准连接得到保持。如前面实施例所示,边缘宽度可以比现有技术的减少,这样将减少由于摩4^插件35、、的侧面80"产生的热量,这样就增加了工具寿命和/或允许工具在高速下操作, 同时可保持工具的使用寿命。应当理解,与平面型扁钻插件结合的螺旋边缘并不限于文中扁钻插件所显示的特征,螺旋边缘的结构可结合其他特定类型的扁钻插件几何形状。因此,螺旋边缘可独立于特定形式的连4^部分,刃部,点半径等,这些可在不同平面型扁钻插件之间变化。例如,如图6A到7B所示,不同类型的角部处理可设置到没有限定的螺旋边缘的扁钻插件。图6A显示了插件 Slot 88 disposed parallel to the coil does not interfere with the edge 82 '8 (the entire radial width of the contact hole is almost the T side, top view shown in FIG. 5B. This enables the plug 35', maintaining the previous embodiments may be provided high stability. 88 slotted hole located radially outward from the place 70, such that the standard connection is being maintained. as shown in the foregoing embodiment, the edge width can be reduced over the prior art, which would reduce the friction plug 4 ^ the side surface 35 ,, 80 "the heat generated, thus increasing the tool life and / or allow the tool to operate at high speed, while maintaining tool life. it should be appreciated that the drill plug with flat planar spiral edges are not bonded limited to the features described in the flat drill widget is displayed, the structure of the helical edges may be combined with other specific types of flat drill plug geometry. Thus, the helical edges may be independent of the particular form of even 4 ^ portion, the blade portion, the point radius, which can be vary between different planar flat drill insert. For example, as shown in FIG. 6A to 7B, the processing of different types of corners may be provided is not limited to a helical edge of the flat plug drill.
