The diagram seen in the direction of the arrow after the -B line is cut corresponds to the above (A).
如圖1(A)及圖2(A)所示，本發明的分度裝置10中，旋轉軸14由周知的軸承20、22、24、26等可旋轉地支持在固定框架12上。前述旋轉軸14的一端側(圖示之例中為上端側)有刀具台16受螺栓18等所固定。在前述刀具台16例如安裝有圖未示的切削工具等。前述旋轉軸14是由設在另一端側(圖示之例中為下端側)而圖未示的馬達等驅動旋轉。或者，也可以在旋轉軸14的適當位置設置圖未示的蝸輪，並將與該蝸輪相咬合的蝸軸連結圖未示的馬達等來驅動旋轉軸14。如此的分度裝置10中，設有定位機構(或鎖固機構)30，用以使前述刀具台16的旋轉停止位置確實地停止在預定的位置上。 As shown in FIGS. 1(A) and 2(A), in the indexing device 10 of the present invention, the rotary shaft 14 is rotatably supported by the fixed frame 12 by well-known bearings 20, 22, 24, 26 and the like. One end side (the upper end side in the illustrated example) of the rotating shaft 14 has a cutter table 16 fixed by a bolt 18 or the like. For example, a cutting tool or the like not shown is attached to the above-described tool holder 16. The rotating shaft 14 is driven to rotate by a motor or the like (not shown) provided on the other end side (the lower end side in the illustrated example). Alternatively, a worm wheel (not shown) may be provided at an appropriate position of the rotating shaft 14, and a rotating shaft 14 may be driven by connecting a worm shaft engaged with the worm wheel to a motor or the like (not shown). In such an indexing device 10, a positioning mechanism (or locking mechanism) 30 is provided for reliably stopping the rotation stop position of the cutter table 16 at a predetermined position.
前述定位機構30是用於將前述旋轉軸14停止保持在預定的旋轉位置者，由移動構件32、支持構件34及50、旋轉軸14側 的擴徑部58、及球體70等所構成。前述移動構件32是設在前述固定框架12與前述旋轉軸14之間且可在該旋轉軸14的軸方向移動，並具有承受球體70的引導面38。本實施例中，前述引導面38是形成在前述旋轉軸14的軸方向上，且形成為具有與前述球體70的表面進行線接觸的曲面形狀的溝(參見圖1(B))。前述引導面38如圖1(A)所示，從軸方向截面看時是下側為垂直部40A而上側為傾斜部40B。而藉由前述引導面38可將球體70往前述旋轉軸14側壓入。 The positioning mechanism 30 is for stopping the rotation of the rotating shaft 14 at a predetermined rotational position, and is composed of the moving member 32, the supporting members 34 and 50, and the rotating shaft 14 side. The enlarged diameter portion 58 and the spherical body 70 are configured. The moving member 32 is provided between the fixed frame 12 and the rotating shaft 14 and is movable in the axial direction of the rotating shaft 14, and has a guiding surface 38 that receives the spherical body 70. In the present embodiment, the guide surface 38 is formed in the axial direction of the rotating shaft 14, and is formed to have a curved groove having a line contact with the surface of the spherical body 70 (see FIG. 1(B)). As shown in FIG. 1(A), the guide surface 38 is a vertical portion 40A on the lower side and an inclined portion 40B on the upper side when viewed in the axial direction. The ball 70 can be pressed into the side of the rotating shaft 14 by the guide surface 38.
又，前述移動構件32靠外周處形成有孔42，收容有做為賦與勢能機構之彈簧44的一端部44A側。該彈簧44的另一端部44B是抵接設於前述移動構件32上方的支持構件50的段部56。而移動構件32藉由前述彈簧44隨時被賦與朝向下方的勢能。 Further, the moving member 32 is formed with a hole 42 at its outer circumference, and accommodates one end portion 44A side of the spring 44 to which the potential energy mechanism is applied. The other end portion 44B of the spring 44 is a segment portion 56 that abuts against the support member 50 provided above the moving member 32. The moving member 32 is always given a potential energy directed downward by the aforementioned spring 44.
此外，前述移動構件32的底面，與設在該移動構件32下方的支持構件34之間，形成有空氣室36。前述固定框架12的側面形成有圖未示的通道，且該通道是形成在即使前述移動構件32在最低位置中也會與前述空氣室36相通的位置。前述通道中設有圖未示的供排氣裝置，該供排氣裝置是設在前述固定框架12的外側。藉由該供排氣裝置對前述空氣室36送氣，則前述移動構件32會上升(圖1(A)的狀態)，相反地從前述空氣室36抽氣，則前述移動構件32會因前述彈簧44的賦與勢能之力而下降(圖2(A)的狀態)。 Further, an air chamber 36 is formed between the bottom surface of the moving member 32 and the support member 34 provided below the moving member 32. A side surface of the fixing frame 12 is formed with a passage (not shown), and the passage is formed at a position where the moving member 32 communicates with the air chamber 36 even in the lowest position. An air supply and exhaust device (not shown) is provided in the passage, and the air supply and exhaust device is provided outside the fixed frame 12. When the air supply chamber 36 supplies air to the air chamber 36, the moving member 32 rises (the state of FIG. 1(A)), and conversely, the air member 36 draws air, and the moving member 32 is caused by the spring. The power of 44 is reduced by the power of potential energy (state of Figure 2 (A)).
接著說明擴徑部58。前述擴徑部58在本實施例中是與旋 轉軸14形成為一體，且成為直徑比該旋轉軸14大的略柱狀(或略圓筒狀)。該擴徑部58的外周面有球溝60面向前述移動構件32的引導面38而在前述旋轉軸14的軸方向形成。該球溝60如圖1(B)與圖2(B)所示，成為具有承受前述球體70之曲面的球溝60。 Next, the enlarged diameter portion 58 will be described. The aforementioned enlarged diameter portion 58 is in the present embodiment The rotating shaft 14 is formed integrally and has a slightly columnar shape (or a slightly cylindrical shape) having a diameter larger than the rotating shaft 14. The outer peripheral surface of the enlarged diameter portion 58 is formed in the axial direction of the rotating shaft 14 with the ball groove 60 facing the guiding surface 38 of the moving member 32. As shown in FIG. 1(B) and FIG. 2(B), the ball groove 60 has a ball groove 60 that receives the curved surface of the spherical body 70.
接著，前述支持構件50配置在前述移動構件32的上方，且具有筒部52配置在前述移動構件32的球溝38與前述擴徑部58的球溝60之間。該筒部52具有保持前述球體70的孔54。前述支持構件50是以適當方法固定在前述固定框架12側。又，前述支持構件50在前述筒部52的周圍形成有段部56，前述彈簧44的另一端部44B是抵接在該段部56。因此，前述移動構件32隨時受到前述彈簧44賦與往下方(刀具台16的相反側)的勢能。 Next, the support member 50 is disposed above the moving member 32, and has a tubular portion 52 disposed between the ball groove 38 of the moving member 32 and the ball groove 60 of the enlarged diameter portion 58. The cylindrical portion 52 has a hole 54 that holds the spherical body 70 described above. The aforementioned support member 50 is fixed to the side of the fixed frame 12 by an appropriate method. Further, in the support member 50, a segment portion 56 is formed around the tubular portion 52, and the other end portion 44B of the spring 44 abuts against the segment portion 56. Therefore, the moving member 32 is always biased by the aforementioned spring 44 to the lower side (opposite side of the tool holder 16).
接著說明本實施例的作用。圖2(A)顯示解鎖狀態。此狀態下未對前述空氣室36進行供氣，而移動構件32受前述彈簧44賦與往下方的勢能。因此，前述球體70受前述移動構件32的引導面38的傾斜部40B支持，而非垂直部40A。也就是從圖2(A)中虛線顯示的鎖固狀態開始，球體往徑方向外側移動，使前述球體70與擴徑部58的球溝60間的卡合解除。若從平面看此狀態，則如圖2(B)所示。也就是定位機構30的鎖固解除，此狀態下旋轉軸14藉由圖未示的驅動機構旋轉，藉此令旋轉軸14旋轉且前述刀具台16也旋轉，使得刀具台16所保持但圖未示的工具的旋轉角度改變。 Next, the action of this embodiment will be described. Figure 2 (A) shows the unlocked state. In this state, the air chamber 36 is not supplied with air, and the moving member 32 is biased downward by the spring 44. Therefore, the aforementioned spherical body 70 is supported by the inclined portion 40B of the guiding surface 38 of the moving member 32, instead of the vertical portion 40A. That is, starting from the locked state shown by the broken line in Fig. 2(A), the ball moves outward in the radial direction, and the engagement between the spherical body 70 and the ball groove 60 of the enlarged diameter portion 58 is released. If this state is seen from the plane, it is as shown in Fig. 2(B). That is, the locking mechanism of the positioning mechanism 30 is released. In this state, the rotating shaft 14 is rotated by a driving mechanism (not shown), whereby the rotating shaft 14 is rotated and the cutter table 16 is also rotated, so that the cutter table 16 is held but the figure is not The angle of rotation of the illustrated tool changes.
如上所述使刀具台16旋轉預定角度後，若要停止旋轉軸14的旋轉而鎖固，則如圖1(A)所示，以圖未示的供排氣裝置對前述空氣室36送氣形成驅動機構。如此可令前述移動構件32對抗前述彈簧44的賦與勢能之力往旋轉軸14的軸方向(圖示之例中為上方)移動。前述移動構件32一上升，則該移動構件32的引導面38所保持的球體70會受前述引導面38的垂直部40A往上推，且從前述支持構件50的孔54內往旋轉軸14側移動，嵌入前述擴徑部58的球溝60。由於被推入旋轉軸14側的球體70受前述引導面38的垂直部40A限制往外側的移動，因此如圖1(B)示，藉由球體70與球溝60的嵌合，可確實地將旋轉軸14鎖固在預定的停止位置。 After the cutter table 16 is rotated by a predetermined angle as described above, if the rotation of the rotary shaft 14 is stopped and locked, as shown in FIG. 1(A), the air chamber 36 is blown by an air supply and exhaust device (not shown). Drive mechanism. In this way, the moving member 32 can be moved against the axial direction of the rotating shaft 14 (upward in the illustrated example) against the force of the spring 44. When the moving member 32 ascends, the ball 70 held by the guiding surface 38 of the moving member 32 is pushed up by the vertical portion 40A of the guiding surface 38, and from the inside of the hole 54 of the supporting member 50 toward the rotating shaft 14 side. The ball groove 60 of the enlarged diameter portion 58 is moved and inserted. Since the ball 70 pushed to the side of the rotating shaft 14 is restricted from moving outward by the vertical portion 40A of the guiding surface 38, the fitting of the ball 70 and the ball groove 60 can be surely shown as shown in Fig. 1(B). The rotating shaft 14 is locked at a predetermined stop position.
在進行如上的鎖固動作時，承受前述球體70的球溝60是具有與前述球體70的表面進行線接觸的曲面形狀的溝(R溝)。也就是，藉由以R溝來保持球體70，因球體70與球溝60間發生摩擦，故能以較大的負載來鎖固。當鎖固狀態解除時，一旦以前述圖未示的供排氣機構從前述空氣室36排出空氣，則移動構件32會因彈簧44的賦與勢能之力而下降，前述球體37往徑方向外側移動，因此該球體70與球溝60之卡合所造成的鎖固會解除，令旋轉軸14可旋轉(圖2(A)及(B))。 When the above-described locking operation is performed, the ball groove 60 that receives the spherical body 70 is a curved groove (R groove) having a line contact with the surface of the spherical body 70. That is, by holding the ball 70 in the R groove, since the ball 70 and the ball groove 60 are rubbed, it can be locked with a large load. When the lock state is released, once the air is exhausted from the air chamber 36 by the air supply and exhaust mechanism (not shown), the moving member 32 is lowered by the force of the spring 44, and the ball 37 is radially outward. Moving, the locking caused by the engagement of the ball 70 with the ball groove 60 is released, and the rotating shaft 14 is rotatable (Figs. 2(A) and (B)).
如此，依據實施例1，由於將分度裝置10構成為包含：旋轉軸，其一端側固定有刀具台；固定框架，是可旋轉地支持該旋 轉軸；移動構件，設於前述固定框架與前述旋轉軸之間並可在該旋轉軸的軸方向移動，且具有承受球體的引導面，以該引導面將前述球體往前述旋轉軸側壓入；球溝，在前述旋轉軸的外周面上，面向前述移動構件的引導面而形成在前述旋轉軸的軸方向，並具有承受前述球體的曲面；及支持構件，配置在前述移動構件的引導面與前述旋轉軸側的球溝之間，具有保持前述球體的孔，且固定於前述固定框架，因此具有如下的效果： Thus, according to the first embodiment, the indexing device 10 is configured to include a rotating shaft, and a cutter table is fixed to one end side thereof; the fixed frame is rotatably supported by the rotating frame a rotating shaft; the moving member is disposed between the fixed frame and the rotating shaft and movable in an axial direction of the rotating shaft, and has a guiding surface that receives the spherical body, and the guiding body presses the spherical body toward the rotating shaft side; The ball groove is formed on the outer circumferential surface of the rotating shaft so as to face the axial direction of the rotating shaft facing the guiding surface of the moving member, and has a curved surface that receives the spherical body; and a supporting member disposed on the guiding surface of the moving member The ball groove on the side of the rotating shaft has a hole for holding the spherical body and is fixed to the fixed frame. Therefore, the ball has the following effects:
(1)能以較簡單的構造來確實地將刀具台16的旋轉鎖固在預定位置。 (1) The rotation of the cutter table 16 can be surely locked in a predetermined position with a relatively simple configuration.
(2)由於旋轉軸14的擴徑部58的球溝60與球體70的表面進行線接觸，因此會發生摩擦力，能以較大的負載來鎖固。 (2) Since the ball groove 60 of the enlarged diameter portion 58 of the rotary shaft 14 is in line contact with the surface of the spherical body 70, frictional force is generated and can be locked with a large load.
(3)由於以移動構件32的R溝形狀的引導面38及支持構件50的孔54來保持球體70，而可固定球體70的位置。因此，無需將球體70設在旋轉軸14的整個周邊，只需設置必要個數(本實施例中為4個)即可。 (3) Since the spherical body 70 is held by the guide surface 38 of the R groove shape of the moving member 32 and the hole 54 of the support member 50, the position of the spherical body 70 can be fixed. Therefore, it is not necessary to provide the sphere 70 over the entire circumference of the rotary shaft 14, and it is only necessary to provide the necessary number (four in the present embodiment).
又，本發明不受上述實施例所限定，可在不脫離本發明要旨的範圍內加入各種變更。例如包含下述： Further, the present invention is not limited to the above embodiments, and various modifications can be added without departing from the spirit and scope of the invention. For example, include the following:
(1)前述實施例中所示的形狀、尺寸乃是其中一例，可視需求作適當的變更。關於材料也可以在達成同樣效果的範圍內使用各種公知的材料。 (1) The shape and size shown in the foregoing embodiments are examples, and may be appropriately changed as needed. Regarding the material, various well-known materials can also be used within the range in which the same effects are achieved.
(2)前述實施例中是設置4個球體70，但這也只是其中一例，可以在達成同樣效果的範圍內適當增減球體70的數量。 (2) In the foregoing embodiment, four balls 70 are provided, but this is only one example, and the number of the balls 70 can be appropriately increased or decreased within a range in which the same effect is achieved.
(3)前述實施例中是將移動構件32的引導面38及擴徑部58的球溝60形成為具有與前述球體70的表面進行線接觸的曲面的R溝，但只要至少將球溝60形成為R溝即可，移動構件32側的引導面38未必要是R溝。 (3) In the above embodiment, the guide surface 38 of the moving member 32 and the ball groove 60 of the enlarged diameter portion 58 are formed as R grooves having a curved surface in line contact with the surface of the spherical body 70, but at least the ball groove 60 is provided. It is sufficient to form the R groove, and the guide surface 38 on the side of the moving member 32 is not necessarily the R groove.

(5)前述實施例中是利用空氣壓作為使移動構件32移動的手段，但這也只是其中一例，可以採用運用其他流體的公知機構。 (5) In the foregoing embodiment, the air pressure is used as a means for moving the moving member 32, but this is only one example, and a known mechanism using other fluids may be employed.
(6)雖然在前述實施例1中未圖示，但也可以設置公知的各種感測器(行程感測器、壓力感測器、移位感測器等)來檢測移動構件32的移動量。 (6) Although not shown in the first embodiment, various known sensors (stroke sensors, pressure sensors, shift sensors, etc.) may be provided to detect the amount of movement of the moving member 32. .
(7)本發明的分度裝置可適用於具有刀具台的各種工具機。 (7) The indexing device of the present invention can be applied to various machine tools having a tool table.
依據本發明，作成為包含：旋轉軸，其一端側固定有刀具台；固定框架，是可旋轉地支持該旋轉軸；移動構件，設於前述固定框架與前述旋轉軸之間並可在該旋轉軸的軸方向移動，且具有承受球體的引導面，以該引導面將前述球體往前述旋轉軸側壓入； 球溝，在前述旋轉軸的外周面上，面向前述移動構件的引導面而形成在前述旋轉軸的軸方向，並具有承受前述球體的曲面；及支持構件，配置在前述移動構件的引導面與前述旋轉軸側的球溝之間，具有保持前述球體的孔，且固定於前述固定框架。因此，能以較簡單的構造來將刀具台的旋轉鎖固在預定的停止位置，故可適用於刀具台的分度裝置之用途。 According to the invention, the rotary shaft has a cutter table fixed to one end side thereof; the fixed frame rotatably supports the rotary shaft; and the moving member is disposed between the fixed frame and the rotating shaft and is rotatable Moving in the axial direction of the shaft and having a guiding surface for receiving the spherical body, and pressing the spherical body toward the rotating shaft side with the guiding surface; The ball groove is formed on the outer circumferential surface of the rotating shaft so as to face the axial direction of the rotating shaft facing the guiding surface of the moving member, and has a curved surface that receives the spherical body; and a supporting member disposed on the guiding surface of the moving member A hole for holding the spherical body is formed between the ball grooves on the side of the rotating shaft, and is fixed to the fixed frame. Therefore, the rotation of the tool table can be locked at a predetermined stop position with a relatively simple structure, so that it can be applied to the use of the indexing device of the tool table.
惟以上所述者，僅為本發明的實施例而已，當不能以此限定本發明實施的範圍，凡是依本發明申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本發明專利涵蓋的範圍內。 However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
