The spinning machine base 50 is divided into front and rear sides and left and right sides, and the spinning machine base 50 The left and right directions are the Z axis, and the direction of the right rear side of the spinning machine base 50 extending toward the left front is the X axis, and a machine tool spindle 51 is disposed on the left side of the top surface of the front half of the spinning machine base 50, and the spinning machine is also A workpiece clamp 52 is disposed on the right side of the top surface of the front half of the base 50, and a Z-axis drive structure 53 is disposed on the top surface of the rear half of the spinner base 50, and a Z-axis is provided along the top of the Z-axis drive structure 53. a Z-axis sliding seat 531 sliding in the axial direction; a bottom plate 54 is disposed on the Z-axis sliding seat 531, the bottom plate 54 is a long plate body extending in the X-axis direction, and two linear sliding rail groups are disposed on the left and right sides of the bottom plate 54 541, a turret carrier 542 is slidably disposed on the linear slide group 541, a ball screw nut 543 is fixed at the bottom of the turret carrier 542, and a turret 55 is coupled to the top surface of the turret carrier 542. A servo motor 56 is coupled to the rear end of the bottom plate 54 and extends forwardly at the front end of the servo motor 56 and is received by the servo motor 56. Moving ball screw 561 rotates, the ball screw 561 screwed into the ball seat 542 at the bottom of the carrier turret Screw nut 543.
前述現有旋壓機需要驅動刀塔55前進對工件進行加工時，如圖7、圖8所示，是以伺服馬達56帶動滾珠螺桿561旋轉，使螺合在滾珠螺桿561的滾珠螺桿螺帽543以及刀塔承載座542前進，帶動刀塔承載座542上的刀塔55一同前移進行加工。 When the conventional spinning machine needs to drive the turret 55 to advance the workpiece, as shown in FIGS. 7 and 8, the servo motor 56 drives the ball screw 561 to rotate, so that the ball screw nut 543 is screwed to the ball screw 561. The turret carrier 542 is advanced to drive the turret 55 on the turret carrier 542 to move forward together for processing.
前述現有旋壓機的滾珠螺桿561配合滾珠螺桿螺帽543的構造雖可驅動刀塔55前進或者後退，但由於滾珠螺桿561驅動作用力的位置是在刀塔55底部的位置，與刀塔55質量最重的本體之間有一段垂直的距離，因此當滾珠螺桿561轉動驅動刀塔承載座542與刀塔55滑動時，滾珠螺桿561的施力相對於刀塔55會產生額外的力矩，因此刀塔55沿線性滑軌組541滑動時會產生較大的靜摩擦力，如此一來除了組裝時需要採用負荷較大的線性滑軌組541以及伺服馬達56，因此使成本上升以外，亦無法以較為靈敏的方式帶動刀塔55前、後移動，不能提升旋壓機的加工精度。 The ball screw 561 of the above-described conventional spinning machine, in conjunction with the structure of the ball screw nut 543, can drive the turret 55 to advance or retreat, but since the position at which the ball screw 561 drives the force is at the bottom of the turret 55, and the turret 55 There is a vertical distance between the heaviest bodies, so when the ball screw 561 rotates to drive the turret carrier 542 to slide with the turret 55, the force applied by the ball screw 561 generates additional torque relative to the turret 55, thus When the turret 55 slides along the linear slide group 541, a large static friction force is generated. In this case, in addition to assembly, a linear load rail group 541 and a servo motor 56 having a large load are required, so that the cost cannot be increased. The more sensitive way to move the turret 55 forward and backward can not improve the machining accuracy of the spinning machine.
由於現有旋壓機驅動刀塔的作用位置是在刀塔的底部，因此造成刀塔滑動的靜摩擦力大而使刀塔移動的靈敏度降低以及構造成本較高的缺點；為此，本發明以刀塔推移構造直接推動刀塔，達到刀塔移動靈敏度高以及降低成本的功效。 Since the position of the existing spinning machine driving the turret is at the bottom of the turret, the static friction of the turret sliding is large, and the sensitivity of the turret movement is lowered and the construction cost is high; therefore, the present invention uses the knives.

當本發明設置在旋壓機時，是以底板的中間結合固定在旋壓機的Z軸線性驅動構造的Z軸滑動座上，並且底板前、後延伸的方向與旋壓機的X軸延伸的方向同向；當需要驅動刀塔前進、後退移動而對工件進行加工時，是以伺服馬達帶動第二時規皮帶輪旋轉，該第二時規皮帶輪會透過時規皮帶使第一時規皮帶輪以及與第一時規皮帶輪結合的旋轉管、滾珠螺桿螺帽一同旋轉，當滾珠螺桿螺帽旋轉時，會帶動與滾珠螺桿螺帽螺合的滾珠螺桿前進或 者後退，如此可利用滾珠螺桿將刀塔的刀塔本體向前推動或者向後拉動，使刀具對工件進行進刀或者退刀的動作。 When the present invention is disposed in the spinning machine, it is fixed on the Z-axis sliding seat of the Z-axis linear driving structure of the spinning machine with the middle of the bottom plate, and the direction of the front and rear extension of the bottom plate and the X-axis extension of the spinning machine The direction is the same direction; when the turret needs to drive the turret forward and backward to process the workpiece, the servo wheel drives the second timing pulley to rotate, and the second timing pulley transmits the first timing pulley through the timing belt. And the rotating tube and the ball screw nut combined with the first timing pulley are rotated together, and when the ball screw nut rotates, the ball screw screwed with the ball screw nut is advanced or The person retreats, so that the turret body of the turret can be pushed forward or pulled backward by the ball screw, so that the tool can feed or retract the workpiece.
本發明的主要功效在於，由於本發明的刀塔推移構造是以滾珠螺桿直接推動刀塔質量最重的刀塔本體移動，因此滾珠螺桿推動或拉動刀塔本體的施力直接不會產生額外力矩，可降低承載刀塔重量的兩線性滑軌組的靜摩擦力以及伺服馬達帶動滾珠螺桿前、後移動的負載，因此本發明在組裝時可選用負荷較輕的線性滑軌組以及伺服馬達，能夠降低構造的費用而具有較佳的經濟效益，並且由於刀塔移動時的靜摩擦力降低，因此刀塔推移構造驅動刀塔動作時，能夠以更加靈敏的方式驅動而能夠提升旋壓機加工的精度。 The main function of the present invention is that since the turret shifting structure of the present invention directly drives the turret body with the heaviest mass of the turret directly by the ball screw, the force applied by the ball screw to push or pull the turret body directly does not generate additional torque. The static friction force of the two linear slide groups carrying the weight of the turret and the load of the servo motor driving the ball screw before and after the movement can be reduced. Therefore, the present invention can be used with a light load linear slide group and a servo motor. The utility model has the advantages of lowering the cost of the structure, and has better economic benefits, and the static friction force when the turret moves is reduced. Therefore, when the turret shifting structure drives the turret, the turret can be driven in a more sensitive manner to improve the precision of the spinning machine. .
此外，由於本發明的第二時規皮帶輪是透過具有彈性的時規皮帶帶動第一時規皮帶輪與滾珠螺桿螺帽旋轉而驅動滾珠螺桿前進、後退，其中具有彈性的時規皮帶能發揮傳動構造之間的緩衝效果，使得伺服馬達帶動滾珠螺桿螺帽的旋轉或者驅動滾珠螺桿前進、後退的動作皆能以更為平順的方式進行，提升旋壓機加工的品質。 In addition, since the second timing pulley of the present invention drives the ball screw to advance and retreat through the elastic timing belt to drive the first timing pulley and the ball screw nut, wherein the elastic timing belt can play the transmission structure. The buffering effect between the servo motor drives the rotation of the ball screw nut or drives the ball screw to advance and retreat in a smoother manner, improving the quality of the spinning machine.

本發明是設置在旋壓機使用，如圖1至圖3所示，該旋壓機40設有一旋壓機底座41，該旋壓機底座41分為前、後兩側與左、右兩側，該旋壓機底座41的左、右方向是Z軸，該旋壓機底座41右後方朝左前方延伸的方向是X軸，在旋壓機底座41前半部頂面的左側設有一機床主軸42，又在旋壓機底座41前半部頂面的右側設有一工件夾固器43，在旋壓機底座41後半部的頂面設有一Z軸線性驅動構造44，在Z軸線性驅動構造44的頂部設有一可受驅動而沿Z軸方向滑動的Z軸滑動座441。 The invention is arranged to be used in a spinning machine. As shown in FIG. 1 to FIG. 3, the spinning machine 40 is provided with a spinning machine base 41. The spinning machine base 41 is divided into front and rear sides and left and right sides. On the side, the left and right directions of the spinning machine base 41 are Z-axis, the direction of the right rear side of the spinning machine base 41 extending toward the left front is the X-axis, and a machine tool is disposed on the left side of the top surface of the front half of the spinning machine base 41. The main shaft 42 is further provided with a workpiece clamper 43 on the right side of the top surface of the front half of the spinning machine base 41, and a Z-axis linear drive structure 44 is disposed on the top surface of the rear half of the spinning machine base 41. The top of 44 is provided with a Z-axis slide seat 441 which is slidable in the Z-axis direction.
當本發明設置在旋壓機40時，是以底板11的中間結合固定在Z軸滑動座441，並且底板11前、後延伸的方向與旋壓機40的X軸延伸的方向同向；當需要驅動刀塔20前進、後退移動而以最前側的刀具23對工件進行加工時，請參看圖3至圖5所示，是以刀塔推移構造30驅動刀塔20前進、後退，驅動方式是以伺服馬達38帶動 第二時規皮帶輪381旋轉，該第二時規皮帶輪381會透過時規皮帶39使第一時規皮帶輪34以及與第一時規皮帶輪34結合的旋轉管33、滾珠螺桿螺帽35一同旋轉，當滾珠螺桿螺帽35旋轉時，會帶動與滾珠螺桿螺帽35螺合的滾珠螺桿36前進或者後退，如此可利用滾珠螺桿36將刀塔20的刀塔本體21向前推動或者向後拉動，使刀具23對工件進行進刀或者退刀的動作。 When the present invention is disposed in the spinning machine 40, the Z-axis sliding seat 441 is fixed in the middle of the bottom plate 11, and the direction in which the bottom plate 11 extends forward and backward is the same as the direction in which the X-axis of the spinning machine 40 extends; When it is necessary to drive the turret 20 to advance and retreat and to machine the workpiece with the tool 23 on the front side, as shown in FIGS. 3 to 5, the turret shifting structure 30 drives the turret 20 to advance and retreat, and the driving mode is Driven by servo motor 38 The second timing pulley 381 rotates, and the second timing pulley 381 rotates the first timing pulley 34 and the rotating tube 33 and the ball screw nut 35 combined with the first timing pulley 34 through the timing belt 39. When the ball screw nut 35 rotates, the ball screw 36 screwed with the ball screw nut 35 is driven forward or backward, so that the turret body 21 of the turret 20 can be pushed forward or backward by the ball screw 36, so that The cutter 23 performs an operation of infeeding or retracting the workpiece.
由於本發明的刀塔推移構造30是以滾珠螺桿36直接推動刀塔20質量最重的刀塔本體21移動，因此滾珠螺桿36推動或拉動刀塔本體21的施力直接不會產生額外力矩，可降低承載刀塔20重量的兩線性滑軌組12的靜摩擦力以及伺服馬達38帶動滾珠螺桿36前、後移動的負載，因此本發明在組裝時可選用負荷較輕的線性滑軌組12以及伺服馬達38，能夠降低構造的費用而具有較佳的經濟效益，並且刀塔推移構造30驅動刀塔20的移動能夠更加的靈敏而能夠提升加工的精度。 Since the turret shifting structure 30 of the present invention directly moves the turret body 21 of the turret 20 with the heaviest mass by the ball screw 36, the force applied by the ball screw 36 to push or pull the turret body 21 directly does not generate an additional torque. The static friction force of the two linear slide groups 12 carrying the weight of the turret 20 and the load of the servo motor 38 moving the front and rear of the ball screw 36 can be reduced, so that the present invention can be used to assemble a lightly loaded linear slide group 12 and The servo motor 38 can reduce the cost of the construction and has better economic efficiency, and the turret shifting structure 30 can drive the movement of the turret 20 to be more sensitive and can improve the processing precision.
此外，本發明的伺服馬達38如同一般的伺服馬達，是以多段角度依次旋轉的方式達到控制輸出旋轉角度的效果，因此當伺服馬達38轉動第二時規皮帶輪381時並非是以完全平順的方式轉動，但由於本較佳實施例的第二時規皮帶輪381是透過具有彈性的時規皮帶39帶動第一時規皮帶輪34與滾珠螺桿螺帽35旋轉而驅動滾珠螺 桿36前進、後退，藉由具有彈性的時規皮帶39的緩衝，使得滾珠螺桿螺帽35的旋轉或者滾珠螺桿36的進、退動作皆能以更為平順的方式進行。 In addition, the servo motor 38 of the present invention has the effect of controlling the output rotation angle in a manner of sequentially rotating at a plurality of stages, like a general servo motor. Therefore, when the servo motor 38 rotates the second timing pulley 381, it is not in a completely smooth manner. Rotating, but since the second timing pulley 381 of the preferred embodiment drives the first timing pulley 34 and the ball screw nut 35 to rotate through the elastic timing belt 39, the roller screw is driven. The rod 36 is advanced and retracted, and the rotation of the ball screw nut 35 or the advancement and retraction of the ball screw 36 can be performed in a smoother manner by the cushioning of the elastic timing belt 39.
承前述，由於本發明的第二時規皮帶輪381是透過具有彈性的時規皮帶39帶動第一時規皮帶輪34與滾珠螺桿螺帽35旋轉，因此滾珠螺桿36的進、退動作平順，加上滾珠螺桿36的軸心與刀盤22的中心以及刀具23的加工端231位於同一水平面，當刀具23加工接觸工件時反作用力會沿著滾珠螺桿36的軸向回推，使滾珠螺桿36推動刀塔20的作用力與刀具23的反作用力皆作用在滾珠螺桿36的軸向，藉由具有彈性的時規皮帶39的緩衝，同樣能使滾珠螺桿36平順地推動刀塔20，使刀具23對工件進刀的速度能更為一致且穩定，能將工件的表面加工得更為光滑無瑕疵。 As described above, since the second timing pulley 381 of the present invention drives the first timing pulley 34 and the ball screw nut 35 to rotate through the elastic timing belt 39, the ball screw 36 is smoothly moved forward and backward. The axis of the ball screw 36 is at the same level as the center of the cutter head 22 and the machining end 231 of the cutter 23. When the cutter 23 is in contact with the workpiece, the reaction force is pushed back along the axial direction of the ball screw 36, causing the ball screw 36 to push the knife. Both the force of the tower 20 and the reaction force of the cutter 23 act on the axial direction of the ball screw 36. By the cushioning of the elastic timing belt 39, the ball screw 36 can also smoothly push the turret 20 so that the cutter 23 is paired. The workpiece feed speed is more consistent and stable, and the surface of the workpiece can be made smoother and smoother.
