M413560 五、新型說明： 【新型所屬之技術領域】 本案與機床有關，特別是有關於一種雙主轴加工機。 【先前技術】 目前對工件進行三維空間加工的加工機，普遍是在一 三維位移裝置上裝一主軸（spindle)。加工時是將一刀具裝 在主軸上，主軸旋轉時帶動刀具對工件加工。由三維方向 移動主軸，能改變工件的加工位置與加工深度。 但要進行不同的加工模式時，必須將刀具從主轴上拆 下，更換新的刀具，相當不便。例如要對工件進行鑽孔與 拋光，必須先將鑽孔的刀具裝在主轴上，待鑽孔作業完畢， 再將鑽孔的刀具由主軸拆下，並將精切削的刀具裝在主轴 上。可知要改變加工模式，必須更換刀具，拖延完工的時 間。 且主軸設置在三維位移裝置時，是設置在三維位移裝 置的一側。因此主轴會對三維位移裝置產生力矩，導致影 響三維位移裝置的平衡與壽命。 【新型内容】 本新型之一技術態樣在於提供一種雙主軸加工機，利 用二主軸能縮短更換加工模式的時間。且二主軸彼此背對 的特徵，還能保持平衡，減少力矩。 根據本新型一實施方式，一種雙主軸加工機，包含一 4 =座、至）—x轴滑軌、—載件、二Y.軸滑軌、二z轴滑 X及一主軸。基座具有—支架。χ轴滑軌設置在基座。 虹件β又置在X轴滑轨’使载件能相對基座位移。二丫轴滑 刀別δ又置在支架的兩侧，且二丫軸滑軌彼此背對。二Ζ 勒滑軌分別設置在二Υ轴滑軌。二主轴分躲置在二Ζ抽 滑執。 【實施方式】 第1圖缚不本新型一實施方式之雙主軸加工機的立體 圖。如圖所不，雙主軸加工機包含一基座1〇〇、至少一 χ 轴滑軌200、-載件30〇、二γ轴滑軌4〇〇、二ζ轴滑執 500以及二主軸600〇基座1〇〇具有一支架11〇(ΐχ軸滑軌 200設置在基座1〇〇。載件3〇〇設置在χ軸滑軌2〇〇，使 載件300能相對基座1〇〇位移。二丫軸滑軌4〇〇分別設置 在支架110的兩側，且二γ軸滑軌4〇〇彼此背對。二2軸 滑執500分別設置在二γ軸滑軌4〇〇。二主軸6〇〇分別設 鲁’置在二Z軸滑軌500。 前述的X軸、丫軸及2軸，是指虛擬的方向，且χ軸、 丫軸及Z轴彼此垂直。前述的滑軌，是指由軌道與滑塊組 成的裝置，且滑塊能在執道上位移，以提供位移的功能。 前述的X軸滑軌200、Y軸滑軌400及2軸滑軌5〇〇，是 指前述滑軌的作動方向分別為χ軸、丫軸及z軸。 加工時’將工件放在载件300上，並在其中一主韩6〇〇 上裝设刀具，便能對工件加工。再者，利用X轴滑軌2〇〇、 Y軸滑執400及Z軸滑軌500，能使主軸6〇〇相對工件進 5 M413560 行二維空間的位移，以改變對工件的加工位置。至於驅動 X轴滑軌200、Y軸滑軌400及Z轴滑軌500作動的技術， 利雜缸或螺桿等技術都能収，由於已是冑知技術，故 不再贅述。 s要更換工件的加工模式時，不需拆下主軸6〇〇的刀 具，只要在另一主軸600上裝設刀具，便能直接用另一主 轴600對工件加工，以縮短更換加工模式。也就是說，二 =軸_能分別使料同刀具，需要更換加I模式時便不 鲁需拆，刀具，只要更換絲6GQ進行加玉即可，能讓加工 更為簡便。再者’由於主軸6⑼裝在ζ轴滑執5〇〇 滑軌500裝在Y軸滑軌_，且二丫轴滑軌_彼此背對， 因此二主軸6〇〇亦彼此背對。如此能保持平衡， ’ 轴600對支架11〇施加的力矩(t〇rque)。 其中’本案更包含-連接件7〇〇，分別與二主轴 連接。利用連接件7〇〇連接二主軸_，能減少主轴 對支架110施加的力矩，並轉換為連接件7⑻的 ^silefoixe)。再者，由於主軸6⑻是裝在z軸滑軌咖， α執500又|在丫軸滑軌伽，因此也能同時減 轴600對Ζ軸滑執5〇〇施加的力以及ζ轴滑轨 軸滑執400施加的力。 野丫 第2圖繪示第！圖之線2_2的剖視圖。如圖所 案更包含-驅動裝置_。驅動裝置_包含一螺 、 -^目820與—轴承咖。二軸承咖設置在基座1〇〇。 螺杯81G兩端分別與二轴承咖連接，且螺桿_沿 L伸—螺巾目82Q間隔設置在載件細。螺桿⑽與二螺 6 M413560 帽820螺合。 前述螺桿謂沿X轴延伸，是_桿_的延伸方向 與X轴滑軌200的作動方向相同。利用轴承_讓螺桿 • _原地空轉’能驅動螺帽咖位移，並帶動載件3〇〇利 用X軸滑轨200相對基座1〇〇位移。且利用二螺帽82〇 與螺桿810螺合’能増加螺㈣82〇冑载件3〇〇的支樓剛 •性’並提升載件300位移時的穩定度，以及消除螺桿81〇 ，螺帽820之間的間隙。至於驅動螺桿_旋轉的技術， 春最常使用的是馬達’由於已是習知技術，故不再贊述。另 外，二螺帽820更設置在載件3〇〇的兩端。能達到結構上 最大的支撐剛性。 參考第1圖，其中各Z軸滑執500包含一 z軸軌道 510及二Z軸滑塊520。二z軸滑塊520設置在Z軸軌道 510。各主軸600設置在各2軸滑軌5〇〇的z軸執道51〇。 也就是說，二Z軸滑塊520設置在Y軸滑執4〇〇，Z軸執 道510相對二Z軸滑塊520位移時，帶動主軸6〇〇位移。 籲如前所述使用二Z軸滑塊520，能提升剛性，也就是說， 讓Z軸滑塊520與Z軸軌道51 〇之間的相對位移更為穩定。 第3圖繪示本新型另一實施方式之雙主軸加工機的立 體圖。如圖所示，各Z轴滑軌500包含一 Z軸軌道51〇及 三Z軸滑塊520。三Z軸滑塊520設置在Z軸軌道51〇。 各主軸600設置在各Z軸滑軌500的Z軸軌道510。也就 是說，三Z轴滑塊520設置在Y轴滑軌400’Z軸軌道51〇 相對三Z軸滑塊520位移時，帶動主轴600位移。如前所 述使用三Z軸滑塊520，能提供比二Z軸滑塊520更高的 7 M413560 剛性，但會降低Z軸滑塊520與Z軸滑執500之間相對位 移的順暢度。根據使用者需求，能選擇適合的Z軸滑塊520 的數量。 參照第1圖，支架110具有一缺口 111。缺口 111與X 軸滑執200相對，使載件300能利用X轴滑軌200在缺口 111内位移。利用Y轴滑執400與Z轴滑執500，能使主 轴600由支架110向載件300上的工件位移。前述支架110 的形狀，一般稱為龍門（gantry)，具有較強的結構剛性與切 鲁 削穩定性，用於加工機相當合適。 【圖式簡單說明】 第1圖繪示本新型一實施方式之雙主軸加工機的立體 圖。 第2圖繪示第1圖之線2-2的剖視圖。 第3圖繪示本新型另一實施方式之雙主軸加工機的立 體圖。M413560 V. New description: [New technical field] This case is related to machine tools, especially related to a double spindle machining machine. [Prior Art] At present, a processing machine that performs three-dimensional processing on a workpiece is generally provided with a spindle on a three-dimensional displacement device. When machining, a tool is mounted on the spindle, and when the spindle rotates, the tool is processed on the workpiece. Moving the spindle in three dimensions can change the machining position and depth of the workpiece. However, when different machining modes are required, it is quite inconvenient to remove the tool from the spindle and replace it with a new one. For example, to drill and polish a workpiece, the drilled tool must be mounted on the spindle. After the drilling operation is completed, the drilled tool is removed from the spindle and the fine-cut tool is mounted on the spindle. It can be seen that to change the machining mode, the tool must be replaced to delay the completion time. When the main shaft is disposed in the three-dimensional displacement device, it is disposed on one side of the three-dimensional displacement device. Therefore, the main shaft generates a torque to the three-dimensional displacement device, which affects the balance and life of the three-dimensional displacement device. [New content] One of the technical aspects of the present invention is to provide a two-spindle machining machine, which can shorten the time for replacing the machining mode by using the two spindles. And the characteristics of the two spindles facing each other can maintain balance and reduce torque. According to an embodiment of the present invention, a twin-spindle machining machine includes a 4=seat, a)-x-axis slide rail, a carrier member, two Y-axis slide rails, two z-axis slides X, and a spindle. The base has a bracket. The x-axis slide is placed on the base. The rainbow member β is placed on the X-axis slide rail to displace the carrier relative to the base. The two-axis slide δ is placed on both sides of the bracket, and the two-axis slides are opposite each other. The two-slide rails are respectively arranged on the two-axis slide rails. The two spindles are hidden in the second stroke. [Embodiment] Fig. 1 is a perspective view of a twin-spindle processing machine in accordance with one embodiment of the present invention. As shown in the figure, the twin-spindle processing machine comprises a base 1〇〇, at least one axle slide 200, a carrier 30〇, two γ-axis slides 4〇〇, a two-axis slide 500 and two spindles 600. The cymbal base 1 has a bracket 11 〇 (the cymbal slide rail 200 is disposed on the pedestal 1 〇〇. The carrier 3 〇〇 is disposed on the cymbal slide rail 2 〇〇 so that the carrier 300 can be opposite to the base 1 〇 〇 displacement. The two 丫 axis slides 4〇〇 are respectively disposed on both sides of the bracket 110, and the two γ-axis slide rails 4〇〇 are opposite to each other. The two 2-axis slides 500 are respectively disposed on the two γ-axis slide rails. The two spindles 6〇〇 are respectively disposed on the two Z-axis slide rails 500. The aforementioned X-axis, 丫-axis and 2-axis are virtual directions, and the χ, 丫 and Z axes are perpendicular to each other. The slide rail refers to a device consisting of a track and a slider, and the slider can be displaced on the road to provide a displacement function. The aforementioned X-axis slide rail 200, Y-axis slide rail 400 and 2-axis slide rail 5〇〇 It means that the moving direction of the above-mentioned slide rails is the χ axis, the 丫 axis and the z axis respectively. When the workpiece is placed on the carrier 300 during processing, and the tool is mounted on one of the main Han 6 ,, the workpiece can be placed on the workpiece. machining. By using the X-axis slide 2〇〇, the Y-axis slide 400 and the Z-axis slide 500, the spindle 6〇〇 can be displaced into the 2 M413560 two-dimensional space relative to the workpiece to change the machining position of the workpiece. The technology of driving the X-axis slide rail 200, the Y-axis slide rail 400, and the Z-axis slide rail 500 can be received by the technology such as the miscellaneous cylinder or the screw, and is not described in detail because it is already known. s Replacement of the workpiece In the mode, it is not necessary to remove the tool of the spindle 6〇〇. As long as the tool is mounted on the other spindle 600, the workpiece can be directly processed by the other spindle 600 to shorten the replacement machining mode. _ can make the material the same tool, need to replace the I mode, it is not necessary to remove, the tool, just replace the wire 6GQ to add jade, can make the processing easier. Again, because the spindle 6 (9) is installed in the shaft The slide rails 500 are mounted on the Y-axis slide rails _, and the two-axis slide rails _ are opposite each other, so the two spindles 6〇〇 are also opposite each other. This can maintain balance, and the shaft 600 applies to the bracket 11〇. Torque (t〇rque). Which 'this case contains more - connecting pieces 7〇〇, respectively with two spindles Connection. By connecting the two main shafts _ with the connecting member 7 ,, the torque applied by the main shaft to the bracket 110 can be reduced and converted into the ^silefoixe of the connecting member 7 (8). Furthermore, since the main shaft 6 (8) is mounted on the z-axis slide rail, the α-execution 500 is on the 丫-axis slide rail, so that the force applied by the shaft 600 on the 滑-axis slipper 5 ζ and the 滑-axis slide rail can be simultaneously reduced. The force applied by the axle slip 400. No. 2 shows the first! A cross-sectional view of line 2_2 of the figure. As shown in the figure, the drive unit_ is included. The drive unit _ contains a screw, - 目 820 and - bearing coffee. Two bearing coffee sets are set on the base 1〇〇. The two ends of the screw cup 81G are respectively connected with the two bearing coffees, and the screw _ is arranged along the extension of the screw head 82Q at the interval of the carrier. The screw (10) is screwed with the two screw 6 M413560 cap 820. The aforementioned screw extends along the X axis, and the direction in which the rod _ extends is the same as the direction in which the X-axis slide 200 is moved. Using the bearing _ let the screw • _ idling in place can drive the nut displacement and drive the carrier 3 to displace the X-axis rail 200 relative to the base 1 。. And the two nuts 82 螺 are screwed with the screw 810 to 'suppleen the screw (four) 82 〇胄 carrier 3 〇〇 刚 刚 ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” ” The gap between 820. As for the technique of driving the screw_rotation, the most commonly used spring is the motor', which is a conventional technique and is therefore not mentioned. In addition, the second nut 820 is disposed at both ends of the carrier 3〇〇. The structural maximum rigidity can be achieved. Referring to Figure 1, each Z-axis slide 500 includes a z-axis track 510 and two Z-axis slides 520. Two z-axis sliders 520 are disposed on the Z-axis track 510. Each of the spindles 600 is disposed on the z-axis of each of the two-axis slides 5〇〇. That is to say, the two Z-axis sliders 520 are disposed on the Y-axis slide 4 〇〇, and when the Z-axis 510 is displaced relative to the two Z-axis slides 520, the spindle 6 〇〇 is displaced. The use of the two Z-axis sliders 520 as described above can increase the rigidity, that is, the relative displacement between the Z-axis slider 520 and the Z-axis track 51 更为 is more stable. Fig. 3 is a perspective view showing a twin spindle processing machine according to another embodiment of the present invention. As shown, each Z-axis slide 500 includes a Z-axis track 51A and a three-Z-axis slider 520. The three Z-axis slider 520 is disposed on the Z-axis rail 51〇. Each spindle 600 is disposed on a Z-axis rail 510 of each Z-axis rail 500. That is to say, the three Z-axis slider 520 is disposed to displace the spindle 600 when the Y-axis rail 400'Z-axis rail 51 is displaced relative to the three-Z-axis slider 520. Using the three Z-axis sliders 520 as previously described provides a higher 7 M413560 stiffness than the two Z-axis sliders 520, but reduces the smoothness of the relative displacement between the Z-axis slider 520 and the Z-axis slider 500. The number of suitable Z-axis sliders 520 can be selected according to user needs. Referring to Fig. 1, the bracket 110 has a notch 111. The notch 111 is opposed to the X-axis slide 200 so that the carrier 300 can be displaced within the notch 111 by the X-axis slide 200. With the Y-axis slide 400 and the Z-axis slide 500, the spindle 600 can be displaced from the holder 110 to the workpiece on the carrier 300. The shape of the aforementioned bracket 110, generally referred to as a gantry, has a strong structural rigidity and a cutting stability, and is suitable for a processing machine.
