Description

鑽銑一體式刀具Drilling and milling integrated tool

本新型是有關於一種刀具，特別是指一種鑽銑一體式刀具。The new model relates to a tool, in particular to a drilling and milling integrated tool.

參閱圖1與圖2，一種習知的攻牙刀具2，適用於設置在一機具1上。該機具1包含一可經驅動而轉動的旋轉件11，以及一由該旋轉件11延伸而能一併轉動，並用以連接該攻牙刀具2的安裝件12。該攻牙刀具2包含一適用於可脫離地連接該安裝件12且沿一軸線L1之方向延伸而呈柱狀的身部21，以及一由該身部21之一端沿該軸線L1延伸的攻牙部22。其中，該身部21適用於可脫離地連接在該安裝件12上，並隨該旋轉件11旋轉。該攻牙部22包括四型形成於外圍並分別位於對角位置且沿平行該軸線L1之方向延伸的攻牙面221(圖1與圖2因繪視角度只繪示三個)、四分別銜接該等攻牙面221之相鄰兩側且界定出二排屑槽220的排屑面222(圖1與圖2因繪視角度只繪示兩個)，以及數個間隔地凸設在每一攻牙面221並用以攻牙的齒刀223。Referring to Figures 1 and 2, a conventional tapping tool 2 is suitable for being set on a tool 1. The tool 1 includes a rotating member 11 that can be driven to rotate, and a mounting member 12 extending from the rotating member 11 and capable of rotating together, and used for connecting the tapping tool 2. The tapping tool 2 includes a cylindrical body 21 adapted to be detachably connected to the mounting member 12 and extending in the direction of an axis L1, and a tapping tool extending from one end of the body 21 along the axis L1牙部22. Wherein, the body 21 is suitable for being detachably connected to the mounting member 12 and rotating with the rotating member 11. The tapping portion 22 includes four tapping surfaces 221 formed on the periphery and located at diagonal positions and extending in a direction parallel to the axis L1 (only three are shown in FIG. 1 and FIG. 2 due to the drawing angle), four respectively The chip removal surfaces 222 that connect the adjacent two sides of the tapping surfaces 221 and define two chip removal grooves 220 (only two are shown due to the drawing angle in Figures 1 and 2), and are protruding at intervals. Each tapping surface 221 is used for tapping a tooth knife 223.

在使用該攻牙刀具2時，首先讓該軸線L1對準該旋轉件11之轉動中心，接著使該身部21套設於該安裝件12上定位，完成將該攻牙刀具2穩固地安裝於該機具1上。當該旋轉件11經驅動後，會一併帶動該攻牙刀具2以該軸線L1為轉軸而高速旋轉，並將該攻牙部22遠離該身部21之一端朝向一待處理的孔洞10推入，該等攻牙面221會一邊沿該孔洞10之延伸方向推進，一邊藉由該等齒刀223產生的切削力，將壁面切削成一螺紋101。然而，在攻牙作業前，必須預先執行鑽出孔洞的前置作業，須使用一用於鑽孔的鑽頭(圖中未繪示)在壁面或物件表面上鑽出該孔洞10，接著才能將該攻牙刀具2推入該孔洞10進行攻牙作業，使得整個加工步驟因需切換不同用途的工具施予加工才能完成該螺紋101，加工步驟不僅較繁瑣，還要因應不同規格之該孔洞10的尺寸，而對應其規格而更換不同該鑽頭與該功牙刀具2，不但使施工人員需要攜帶更多工具而不便利，施工效率也因而下降許多，故以上缺失有該改善。When using the tapping tool 2, first align the axis L1 with the center of rotation of the rotating part 11, and then set the body 21 on the mounting part 12 for positioning to complete the stable installation of the tapping tool 2 On the implement 1. When the rotating member 11 is driven, it will also drive the tapping tool 2 to rotate at a high speed with the axis L1 as a rotation axis, and push the tapping portion 22 away from the end of the body 21 toward a hole 10 to be processed When the tapping surface 221 advances along the extending direction of the hole 10, the cutting force generated by the tooth cutters 223 cuts the wall surface into a thread 101. However, before the tapping operation, the pre-operation of drilling the hole must be performed in advance. A drill bit for drilling (not shown in the figure) must be used to drill the hole 10 on the wall or object surface, and then the The tapping tool 2 is pushed into the hole 10 for tapping operation, so that the entire processing step needs to switch tools for different purposes to perform processing to complete the thread 101. The processing steps are not only cumbersome, but also corresponding to different specifications of the hole 10 The size of the drill and the tool 2 are changed according to its specifications, which not only makes it inconvenient for construction workers to carry more tools, but also reduces construction efficiency. Therefore, the above shortcomings can be improved.

因此，本新型之目的，即在提供一種能同時鑽孔與絲攻的鑽銑一體式刀具。Therefore, the purpose of the present invention is to provide a drilling and milling integrated tool capable of simultaneously drilling and tapping.

於是，本新型鑽銑一體式刀具，包含一沿一軸線延伸而呈柱狀的基座、一設置於該基座之外周圍的銑牙單元，以及一設置於該基座之一端的鑽孔單元。該銑牙單元包括數個沿該軸線之方向延伸且相互間隔地設置在該基座之外周圍的銑牙件，相鄰兩銑牙件與該基座共同界定出一位於該等銑牙件之間的第一排屑槽，每一銑牙件包括數個彼此平行間隔設置的齒刀。該鑽孔單元包括數個圍繞該軸線分佈的鑽孔件，每一鑽孔件具有一往該軸線之延伸方向凸伸的鑽孔刃。Therefore, the novel integrated drilling and milling tool includes a base extending along an axis and in a columnar shape, a milling unit provided around the base, and a drilling hole provided at one end of the base unit. The milling unit includes a plurality of milling pieces extending along the axis and spaced apart from each other around the base. Two adjacent milling pieces and the base jointly define a milling piece located on the base In the first chip flute, each milling piece includes several tooth cutters arranged in parallel and spaced apart from each other. The drilling unit includes a plurality of drilling elements distributed around the axis, and each drilling element has a drilling edge protruding toward the extending direction of the axis.

本新型之功效在於：由於該等銑牙件與該等鑽孔件是沿該軸線之方向依序設置在該基座上的設計，因此配合一數控工具機的控制時，能先透過該等鑽孔刃鑽出一孔洞，同時，該孔洞會受到該等齒刀的切削作業而形成內螺紋，使得該孔洞同時成為一螺孔，因此僅需要上述單一的操作步驟，即可達到鑽孔銑牙一體化的功效，進而提升加工效率。The effect of the present invention is that since the milling parts and the drilling parts are arranged on the base in sequence along the axis direction, they can be controlled by a numerical control machine tool first. The drilling edge drills a hole, and at the same time, the hole is subjected to the cutting operation of the tooth cutters to form an internal thread, so that the hole becomes a screw hole at the same time, so only the above single operation step is required to achieve drilling and milling The effect of tooth integration, thereby improving processing efficiency.

在本新型被詳細描述之前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

參閱圖3，為本新型鑽銑一體式刀具的一第一實施例，適用於設置在一以電腦數值控制(Computer Numerical Control，CNC)的工具機或車床(圖3未繪示)。該第一實施例包含一沿一軸線L2延伸而呈柱狀的基座4、一設置在該基座4之外周圍的銑牙單元5，以及一設置在該基座4之一端的鑽孔單元6。Refer to FIG. 3, which is a first embodiment of the new drilling and milling integrated tool, which is suitable for a computer numerical control (CNC) machine tool or lathe (not shown in FIG. 3). The first embodiment includes a cylindrical base 4 extending along an axis L2, a milling unit 5 disposed around the base 4, and a drill hole disposed at one end of the base 4 Unit 6.

該基座4較佳由金屬所製成，藉由較強的材料強度，因而能承受較高壓的環境，藉此增長使用壽命。該基座4包括一呈圓柱狀並適用於連接該工具機的安裝部41，以及一由該安裝部41之一端沿該軸線L2延伸的加工部42。The base 4 is preferably made of metal. With strong material strength, it can withstand a higher pressure environment, thereby increasing the service life. The base 4 includes a cylindrical mounting portion 41 suitable for connecting to the machine tool, and a processing portion 42 extending from one end of the mounting portion 41 along the axis L2.

該銑牙單元5包括二沿該軸線L2之方向螺旋延伸，且相互間隔地圍繞該加工部42之周圍的銑牙件51。每一銑牙件51包括數個沿該軸線L2之延伸方向間隔地設置，並沿垂直該軸線L2之方向延伸的齒刀511，其中，該等銑牙件51與該加工部42共同界定出二位於該等銑牙件51之間而彼此相互間隔，且沿該軸線L2之方向延伸而呈螺旋狀的排屑槽50(圖3因繪示角度只繪示一個)。特別說明的是，該銑牙單元5由該基座4一體延伸而形成，因此材料為與該基座4相同的金屬材料，能藉由材料較高的硬度，並配合該工具機轉動所產生的力矩，藉此產生較高的切削力，用來挖除材料而產生一螺紋312(圖3未繪示)。The tooth milling unit 5 includes two tooth milling pieces 51 extending spirally along the axis L2 and surrounding the machining portion 42 at intervals. Each milling piece 51 includes a plurality of tooth cutters 511 arranged at intervals along the extending direction of the axis L2 and extending in a direction perpendicular to the axis L2, wherein the milling pieces 51 and the processing portion 42 jointly define Two helical chip flutes 50 are located between the tooth milling pieces 51 and are spaced apart from each other, and extend along the axis L2 in a spiral shape (only one is shown in FIG. 3 due to the angle of drawing). In particular, the milling unit 5 is formed by integrally extending the base 4, so the material is the same metal material as the base 4, which can be produced by the higher hardness of the material and the rotation of the machine tool The torque of φ, thereby generating a higher cutting force, is used to dig out the material to produce a thread 312 (not shown in FIG. 3).

該鑽孔單元6包括二分別由該等銑牙件51延伸的鑽孔件61，每一鑽孔件61具有一往該軸線L2之延伸方向凸伸的鑽孔刃611。該等鑽孔刃611為呈塊狀的刀片，較佳為四曲線成形刀片，但不以此為限，該等鑽孔刃611可拆離地沿垂直該軸線L2之方向分別鎖接在該等鑽孔件61上。The drilling unit 6 includes two drilling parts 61 respectively extending from the milling parts 51, each drilling part 61 has a drilling edge 611 protruding in the extending direction of the axis L2. The drilling blades 611 are block-shaped blades, preferably quad-curved blades, but not limited to this. The drilling blades 611 are detachably locked to the axis L2 in a direction perpendicular to the axis L2. Wait for the drilled piece 61.

參閱圖4至圖6，定義每一鑽孔刃611在該基座4上投影出一投影線段62，每一投影線段62在徑向方向形成一鄰近該軸線L2的內端點621，以及一相反於該內端點621而鄰近該基座4之外周圍的外端點622。在該第一實施例中，該鑽孔單元6可依照加工需求而調整該等鑽孔刃611彼此間的相對位置，因而產生以下三種態樣：圖4所示的第一種態樣為該等投影線段62彼此相互平行，且該等內端點621彼此貼齊於該軸線L2上；圖5所示的第二種態樣為為該等投影線段62部分疊合，且該軸線L2是位於每一投影線段62的該內端點621與該外端點622之間；圖6所示的第三種態樣為為該等投影線段62彼此相間隔，該等內端點621間隔設置於該之該軸線L2之周圍。4 to 6, it is defined that each drilling edge 611 projects a projection line 62 on the base 4, and each projection line 62 forms an inner end point 621 adjacent to the axis L2 in the radial direction, and a Contrary to the inner end 621 and adjacent to the outer end 622 outside the base 4. In the first embodiment, the drilling unit 6 can adjust the relative positions of the drilling blades 611 to each other according to the processing requirements, thereby generating the following three aspects: the first aspect shown in FIG. 4 is this The equal projection line segments 62 are parallel to each other, and the inner end points 621 are aligned with each other on the axis L2; the second aspect shown in FIG. 5 is that the projection line segments 62 are partially overlapped, and the axis L2 is Located between the inner end point 621 and the outer end point 622 of each projection line segment 62; the third aspect shown in FIG. 6 is that the projection line segments 62 are spaced apart from each other, and the inner end points 621 are spaced apart Around the axis L2.

另參閱圖7至圖8，在垂直該軸線L2之方向的觀點下，該等鑽孔刃611之外周緣形成一條彎折的假想輪廓線C，因此在承載於相同尺寸之該基座4的情況，該假想輪廓線C會隨著該鑽孔單元6的不同態樣而呈現不同的曲率半徑。當該鑽孔單元6為第一種態樣時，如圖7所示該假想輪廓線C的曲率半徑較小，也就是說，在視覺上該假想輪廓線C的曲度較大；當該鑽孔單元6為第二種態樣時，如圖8所示該假想輪廓線C的曲率半徑較大而起伏較平緩，使得曲度相對於前述第一種態樣較小。7-8, from the point of view of the direction perpendicular to the axis L2, the outer periphery of the drilling blades 611 forms a curved imaginary contour line C. Therefore, when the base 4 of the same size is carried In some cases, the imaginary contour line C will present different radii of curvature with different aspects of the drilling unit 6. When the drilling unit 6 is in the first aspect, as shown in FIG. 7, the radius of curvature of the imaginary contour line C is small, that is to say, the curvature of the imaginary contour line C is visually larger; When the drilling unit 6 is in the second aspect, as shown in FIG. 8, the radius of curvature of the imaginary contour line C is larger and the fluctuations are relatively gentle, so that the curvature is smaller than that of the first aspect.

參閱圖9與圖10，使用該第一實施例時，先將該基座4安裝於該工具機(圖9與圖10未繪示)上，並透過電腦數值的計算與控制，操作該第一實施例對一物件3執行加工作業。首先，先將該鑽孔單元6沿一與該軸線L2相互平行之副軸線L3自轉，並對準該物件3推進而執行初步鑽孔作業，產生一小孔(圖未繪示)。接著，由於受到該工具機的控制，該第一實施例將會以該軸線L2為轉軸而高速自轉，且圍繞該副軸線L3而在該小孔內公轉，並沿該副軸線L3之方向繼續推進。透過等鑽孔刃611配合自轉所產生的力矩，藉此產生較高的切削力，將該小孔挖除出一圍繞該副軸線L3而延伸且內徑大於該小孔內徑的孔洞31，以達成鑽孔的作業。同時，透過該實施例以該副軸線L3為中心公轉，並沿該副軸線L3之方向繼續推進。當該銑牙單元5接觸圍繞該孔洞31之一壁面311時，該等齒刀511會開始切削該壁面311而產生與該等齒刀511型態吻合的缺口，隨著該銑牙單元5一邊圍繞該副軸線L3轉動而切削該壁面311，一邊沿該副軸線L3之方向推進，使得所述缺口會沿該副軸線L3之方向螺旋延伸而產生該螺紋312，在單一步驟下同時完成銑牙的作業。特別說明的是，由於鑽孔步驟及銑牙步驟全程都依照電腦的精密計算與精準控制，包括自轉速度與公轉速度皆能精準控制，所以該等齒刀511能不間斷地切削該壁面311產生延續的缺口，進而加工出相同螺距及相同大小的該螺紋312。該工具機也能調整該第一實施例與該副軸線L3間的距離，進而預測加工後之孔洞31的內徑大小，能依照不同的需求將該物件3加工出不同尺寸的孔洞31。9 and 10, when using the first embodiment, the base 4 is first installed on the machine tool (not shown in FIGS. 9 and 10), and the computer is used to calculate and control the numerical value. An embodiment performs processing operations on an object 3. First, the drilling unit 6 rotates along a secondary axis L3 that is parallel to the axis L2, and is aligned with the object 3 to advance to perform a preliminary drilling operation to generate a small hole (not shown). Then, due to the control of the machine tool, the first embodiment will use the axis L2 as the rotation axis to rotate at a high speed, and revolve in the small hole around the secondary axis L3, and continue along the direction of the secondary axis L3 Advance. Through the moment of the drilling edge 611 cooperated with the rotation to generate a higher cutting force, the small hole is dug out a hole 31 extending around the secondary axis L3 and having an inner diameter larger than the inner diameter of the small hole. To achieve drilling operations. At the same time, through this embodiment, it revolves around the secondary axis L3 and continues to advance in the direction of the secondary axis L3. When the milling unit 5 touches a wall surface 311 surrounding the hole 31, the tooth cutters 511 will start to cut the wall surface 311 to produce a gap that matches the shape of the tooth cutters 511. Rotate around the secondary axis L3 to cut the wall surface 311, while advancing in the direction of the secondary axis L3, so that the notch will spirally extend in the direction of the secondary axis L3 to produce the thread 312, and complete milling in a single step Homework. In particular, since the drilling step and the milling step are all accurately calculated and controlled by the computer, including the rotation speed and revolution speed can be accurately controlled, the tooth cutters 511 can cut the wall surface 311 without interruption. The continuous gap is further processed to produce the thread 312 with the same pitch and the same size. The machine tool can also adjust the distance between the first embodiment and the secondary axis L3 to predict the inner diameter of the hole 31 after processing, and can process the object 3 into holes 31 of different sizes according to different requirements.

需要另外說明的是，由於該第一實施例的尺寸加大時，則在銑牙步驟中所受到的扭力亦會增加，因此須調整該等銑牙件51的數量，以達到較高的結構強度來滿足加工的扭力需求，也就是說，該等銑牙件51之數量可以為兩個、四個、六個，或是其他數量，而該等鑽孔件61之數量則延續該等銑牙件51而形成相對應數量。除了上述說明以外，該第一實施例還能呈現不同結構型態的實施態樣。如圖11所示，能改變該等銑牙件51的延伸形狀，藉此應對不同的加工規格與需求，故該等銑牙件51之延伸形狀不以上述呈螺旋狀為限，該等銑牙件51亦可以是沿平行該軸線L2之方向延伸。It should be noted that when the size of the first embodiment increases, the torque received during the milling step will also increase, so the number of milling parts 51 must be adjusted to achieve a higher structure Strength to meet the processing torque requirements, that is, the number of milling parts 51 can be two, four, six, or other numbers, and the number of drilling parts 61 continues the milling The teeth 51 form a corresponding number. In addition to the above description, the first embodiment can also present implementation aspects of different structural types. As shown in Figure 11, the extended shape of the milling parts 51 can be changed to meet different processing specifications and requirements. Therefore, the extended shape of the milling parts 51 is not limited to the above-mentioned spiral shape. The teeth 51 can also extend in a direction parallel to the axis L2.

參閱圖12，為本新型鑽銑一體式刀具的一第二實施例，與該第一實施例的差異之處為該等鑽孔刃611的連接關係。具體而言，該等鑽孔件61分別由該等銑牙件51一體延伸，每一鑽孔刃611由個別的鑽孔件61沿該軸線L2之方向一延伸而呈圓弧狀。因此，該第二實施例在製造程序上，可直接在模具中成形，使得製程較簡單，因而能配合市場需求而大量生產。Refer to FIG. 12, which is a second embodiment of the new drilling and milling integrated tool. The difference from the first embodiment is the connection relationship of the drilling edges 611. Specifically, the drilling elements 61 are respectively integrally extended by the milling elements 51, and each drilling edge 611 is extended by a respective drilling element 61 in the direction of the axis L2 to form an arc shape. Therefore, in the manufacturing process of the second embodiment, it can be directly formed in the mold, making the manufacturing process relatively simple, and thus can be mass-produced according to market demand.

參閱圖13，為本新型鑽銑一體式刀具的一第三實施例，與該第一實施例的差異之處為該等銑牙件51的連接關係。具體而言，該基座4之外周圍向內凹陷形成數個相互間隔的連接槽40，該等銑牙件51分別可脫離地設置於該等連接槽40內，並透過螺絲固定在該基座4上。該第三實施例可在加工現場快速地替換不同規格的銑牙件51，來滿足不同的加工需求，藉此提升通用性。Refer to FIG. 13, which is a third embodiment of the new drilling and milling integrated tool. The difference from the first embodiment is the connection relationship of the milling parts 51. Specifically, the outer periphery of the base 4 is recessed inward to form a plurality of connecting grooves 40 spaced apart from each other. The milling parts 51 are respectively detachably disposed in the connecting grooves 40 and fixed to the base by screws. Seat 4. The third embodiment can quickly replace tooth milling parts 51 of different specifications at the processing site to meet different processing requirements, thereby improving versatility.

參閱圖14，為本新型鑽銑一體式刀具的一第四實施例，與該第三實施例的差異之處為該鑽孔單元6係可脫離地螺接於該基座4上，除了能在耗損時簡便地替換，也能因應不同的加工需求更換所需的專用工件，使得該第四實施例比該第三實施例可以滿足更多的加工需求。Refer to Figure 14, which is a fourth embodiment of the new drilling and milling integrated tool. The difference from the third embodiment is that the drilling unit 6 is detachably screwed to the base 4, except for the ability to It can be easily replaced when it is worn out, and the required special workpieces can also be replaced according to different processing requirements, so that the fourth embodiment can meet more processing requirements than the third embodiment.

綜上所述，本新型鑽銑一體式刀具藉由該鑽孔單元6與該銑牙單元5一同設置在該基座4上的設計，配合該等鑽孔刃611與該等齒刀511的作用下，僅需單一個操作步驟即可同時執行鑽孔與銑牙的作業，以達到鑽孔銑牙一體化的功效，藉此提高施工效率。另外，透過以電腦數值控制的工具機操作，將該鑽銑一體式刀具能圍繞著該副軸線L3推進，藉此加工出一尺寸比自身結構還大，且內徑規格能自由改變的螺孔30，來提升加工的變化性與準確性，故確實能達成本新型之目的。To sum up, the new drilling and milling integrated tool of the present invention uses the design that the drilling unit 6 and the milling unit 5 are arranged on the base 4 together, and it is matched with the drilling edges 611 and the tooth cutters 511. Under the action, only a single operation step can perform drilling and milling operations at the same time, so as to achieve the integrated effect of drilling and milling, thereby improving construction efficiency. In addition, through the operation of a computer numerically controlled machine tool, the drilling and milling integrated tool can be advanced around the secondary axis L3, thereby processing a screw hole whose size is larger than its own structure and whose inner diameter can be freely changed. 30, to improve the variability and accuracy of processing, so it can indeed achieve the purpose of new cost.
