上記特許文献6記載の砥石成形方法は、ワークテーブルの左右両端上に振り分けて固定型のロータリードレッサー(27)装置と首振り型の単石ダイヤモンドドレッサー装置(29)の2基を載置し、先に固定型のロータリードレッサー(27)装置を用いて砥石車(17)の左右移動による砥石車の厚み方向の外周面のドレス加工、および、砥石車(17)の上下移動による砥石車の直径方向前側面と後ろ側面の粗ドレス加工を行った後、次いで、首振り型の単石ダイヤモンドドレッサー装置(29)を用いて倣い用ドレス成形プログラムに従って前記砥石車(17)を倣い成形して仕上げる方法である。この2基の成形装置を用いる研削盤は、ワークピースの研削加工前、研削終了後、研削途中のいずれの場合でも砥石車のドレス加工を行うことができる利点を有する。   In the grinding stone forming method described in Patent Document 6, two units, a fixed rotary dresser (27) device and a swing-type single stone diamond dresser device (29), are placed on the left and right ends of the work table, First, using a fixed rotary dresser (27) device, dressing of the outer peripheral surface in the thickness direction of the grinding wheel by the lateral movement of the grinding wheel (17) and the diameter of the grinding wheel by the vertical movement of the grinding wheel (17). After performing rough dressing on the front side surface and the rear side surface, the grinding wheel (17) is then copied and finished using a swinging type single stone diamond dresser device (29) according to a copying dress forming program. Is the method. The grinding machine using these two molding apparatuses has the advantage that the grinding wheel can be dressed before grinding the workpiece, after grinding, or during grinding.

しかし、平面研削盤や成形研削盤において、ワークピースの大きい製品を加工する場合に、ワークテーブルの左右両端上にドレッサー装置が置かれるのは、ワークテーブルの左右寸法から判断して研削作業がし難いこととなるので、ワークピースの研削加工前または加工終了後に、ワークテーブル上に載置されていたロータリードレッサー装置(27)で粗ドレス加工を行い、ついで、ロータリードレッサー装置(27)を首振り型の単石ダイヤモンドドレッサー装置(29)に置き換え、首振り型の単石ダイヤモンドドレッサー装置(29)で仕上げドレス加工を行うことがある。   However, when machining products with large workpieces on surface grinders and forming grinders, the dresser devices are placed on both the left and right ends of the work table because of the grinding work, judging from the left and right dimensions of the work table. Since this is difficult, rough dressing is performed with the rotary dresser device (27) placed on the work table before or after the workpiece is ground, and then the rotary dresser device (27) is swung. Instead of a single-stone diamond dresser device (29), finish dressing may be performed with a swing-type single-stone diamond dresser device (29).

ロータリードレッサー装置を首振り型のロータリードレッサー装置とし、首振り型の単石ダイヤモンドドレッサー装置(29)と一体化した首振り型の砥石成形装置とすれば、この砥石成形装置の据え付け面積も小さくすることができる。   If the rotary dresser device is a swing type rotary dresser device and a swing type grindstone forming device integrated with the swing type single stone diamond dresser device (29), the installation area of the grindstone forming device is also reduced. be able to.

Claim 1 of the present invention provides
A grinding wheel that is rotatably supported around the grinding wheel axis of the grinding device,
An angle adjustment mechanism for rotating the forming wheel base by turning the turning shaft by driving the servo motor to adjust the angle of the forming wheel with respect to the grinding surface of the grinding wheel,
The forming grindstone base is provided at the longitudinal end of the axis of the swivel shaft, and a rotary dresser device and a single stone diamond dresser device are provided on the forming grindstone table. A diameter surface of the forming grindstone of the rotary dresser device is a diameter surface of the grinding wheel. Parallel and so that the vertical surface including the diameter of the forming wheel includes the forming axis of the single stone diamond wheel of the single stone diamond dresser device,
The base of the single stone diamond dresser device is provided so that the dovetail groove provided on the right side of the molding grindstone can move in the front-rear direction,
In the single stone diamond dresser device, a support portion for fixing the single stone diamond grindstone is provided so as to be movable up and down in the shank storage gripping cylinder, and the molding stone center axis of the rotary dresser device and the single stone It is a single stone diamond dresser device capable of making the diamond grinding wheel have the same molding axis height.
It is an object of the present invention to provide a swing-type grindstone molding apparatus characterized by this.

摩耗が少なく、切れ味を長く保持することができるロータリードレッサー装置および切れ味が良好な単石ダイヤモンドドレッサー装置を併用して砥石車を成形することになるので、単石ダイヤモンドドレッサー装置の単石ダイヤモンド砥石交換時期(寿命)を長くすることができる。   Since a grinding wheel is formed by using a rotary dresser device that has low wear and keeps the sharpness long, and a single stone diamond dresser device that has good sharpness, the single stone diamond wheel replacement of the single stone diamond dresser device Time (life) can be extended.

ロータリードレッサー装置を首振り型のロータリードレッサー装置とし、首振り型の単石ダイヤモンドドレッサー装置と一体化した首振り型の砥石成形装置としたので、この砥石成形装置の据え付け面積を小さくすることができる。かつ、ロータリードレッサー装置による砥石車のドレス加工プログラムと単石ダイヤモンドドレッサー装置による砥石車のドレス加工プログラムを設計する際、砥石車の右方向(X軸方向)にk長さ移動して単石ダイヤモンドドレッサー装置による砥石成形プログラムは、ロータリードレッサー装置による砥石車のドレス加工プログラムにおいて砥石車のX座標(X)をロータリードレッサー装置のロータリー成形砥石と単石ダイヤモンド砥石間の離間距離k分補正したX座標(Xi+k)に変更し、砥石車の高さ方向(Y軸方向)の砥石軸座標を(Yi+h)に変更するドレス加工プログラムで行うことができるので、ドレス加工プログラムのシステム設計が容易である。ここに、hは、ロータリー成形砥石の成形(ドレス)軸心と単石ダイヤモンド砥石の成形(ドレス)軸心高さの差の値である。 Since the rotary dresser device is a swing-type rotary dresser device and a swing-type grindstone molding device integrated with a swing-type single stone diamond dresser device, the installation area of the grinding stone molding device can be reduced. . Also, when designing a grinding wheel dressing program with a rotary dresser and a grinding wheel dressing program with a single stone diamond dresser, move the k length to the right (X-axis direction) of the grinding wheel and move the single stone diamond. In the grinding wheel forming program by the dresser device, the X coordinate (X i ) of the grinding wheel is corrected by the separation distance k between the rotary forming wheel of the rotary dresser device and the single stone diamond wheel in the dressing program of the grinding wheel by the rotary dresser device. It is possible to change to the coordinates (X i + k ) and change the grinding wheel axis coordinate in the height direction (Y axis direction) of the grinding wheel to (Y i + h ), so the system design of the dressing program is easy It is. Here, h is a value of a difference in height between the forming (dress) axis of the rotary forming grindstone and the forming (dress) axis of the single stone diamond grindstone.

The vertical surface (S x ) including the diameter of the rotary forming grindstone (27a) is such that the diameter surface of the grindstone (27a) is parallel to the diameter surface of the grinding wheel, and the forming axis of the single stone diamond grindstone (29a) It is possible to arrange them side by side so as to include the center plane (S x ). (See Figure 2)

単石ダイヤモンド砥石(29a)は市販品を用いることが可能であり、単石ダイヤモンドを固定する支持部がシャンク収納把持筒内に上下移動可能に設けられており、前記ロータリードレッサー装置の成形砥石(27a)の成形軸心(Y)と前記単石ダイヤモンド砥石(29a)の成形軸心(Y)の高さ(H)を同じくすることが可能である。図1において、ロータリー成形砥石(27a)の回転軸心と単石ダイヤモンド砥石(29a)軸心間の距離(k)は、100.75mmである。 As the single stone diamond grindstone (29a), a commercially available product can be used, and a support portion for fixing the single stone diamond is provided so as to be movable up and down in the shank storage gripping cylinder. It is possible to make the forming axis (Y H ) of 27a) the same as the height (H) of the forming axis (Y H ) of the single-stone diamond grindstone (29a). In FIG. 1, the distance (k) between the rotational axis of the rotary forming grindstone (27a) and the axis of the single stone diamond grindstone (29a) is 100.75 mm.

成形砥石(27a,29a)の成形軸心とは、砥石車(17)の研削面に成形砥石の刃先が接触して砥石車をドレッシングしている際の接触点軌跡と成形砥石(27a,29a)の直径方向または高さ方向を結ぶ直線が交差する旋回軸心点であって、成形砥石(27a,29a)の刃先の旋回軸心とも言える。ロータリー成形砥石(27a)の直径方向に位置する前記旋回軸心とこの旋回軸心を含む平面(S)の成形砥石直径の最高の高さ位置間の距離(h)は市販品のロータリー成形砥石で0.3〜1.2mm、単石ダイヤモンド砥石(29a)の前記旋回軸心と単石ダイヤモンド砥石頭頂高さ間の距離(h)は0.1〜0.3mmであるので、両方の成形砥石(27a,29a)刃先の旋回(成形)軸心が同一高さ(H)となるよう、ドレス成形開始前の単石ダイヤモンド砥石の砥石頭頂高さをh(h=hr-hs)だけ上げて支持アーム(8c)に把持されている単石ダイヤ

The forming axis of the forming wheel (27a, 29a) is the contact point locus when the grinding wheel is dressed by the tip of the forming wheel coming into contact with the grinding surface of the grinding wheel (17) and the forming wheel (27a, 29a). ) In the diameter axis direction or the height direction intersecting the axis of rotation intersects, and can also be said to be the axis of rotation of the cutting edge of the forming grindstone (27a, 29a). The distance between the highest height position of the shaped grinding wheel diameter of a plane containing the swivel axis and the swivel axis located in the diametrical direction of the rotary molded grinding wheel (27a) (S X) ( h r) Rotary commercial products The distance (h s ) between the swivel axis of the single stone diamond grindstone (29a) and the height of the single stone diamond grindstone head height is 0.1 to 0.3 mm with a molding grindstone of 0.3 to 1.2 mm. The whetstone top height of the single stone diamond whetstone before starting dress molding is set to h (h = hr-hs) so that the turning (forming) axes of both forming whetstones (27a, 29a) have the same height (H). ) And the height of the single stone diamond grindstone (29a) held by the support arm (8c) is adjusted. (See Figure 1)

この首振り型の砥石成形装置(100)を用いて研削装置(1)の砥石軸(16)に軸承された砥石車(17)の研削面をドレス加工する操作は次のように行われる。   The operation of dressing the grinding surface of the grinding wheel (17) supported by the grinding wheel shaft (16) of the grinding device (1) using the swing-type grinding wheel molding device (100) is performed as follows.

1)ドレス加工前にロータリー成形砥石(27a)の直径方向を含む垂直面(S)の延長上に単石ダイヤモンド砥石(29a)の頭頂と成形軸心を含む垂直面(S)が存在するよう単石ダイヤモンド砥石(29a)基部を前後方向に移動する。(図2参照) 1) there is a vertical plane (S X) containing parietal and molding axis of a single stone diamond wheel on the extension of the vertical plane (S X) (29a) comprising a diametrical direction of the rotary molded grinding wheel (27a) before dress machining The base of the single stone diamond grindstone (29a) is moved in the front-rear direction. (See Figure 2)

2)ドレス加工前にロータリー成形砥石(27a)の成形軸心と単石ダイヤモンド砥石(29a)の成形軸心の高さ(Y)が同一となるよう単石ダイヤモンド砥石(29a)の高さ位置を調整する。(図1参照) 2) molding axis forming the axis of the height of the heart and a single stone diamond grindstone (29a) (Y H) the height of the same and so as single stone diamond wheel (29a) of the rotary molded grinding wheel (27a) before dress machining Adjust the position. (See Figure 1)

この首振り型の砥石成形装置(100)のロータリードレッサー装置(27)の駆動モーター(27m)を駆動させてロータリー成形砥石(27a)を回転軸(27c)廻りに回転させる。   The drive motor (27m) of the rotary dresser device (27) of the swing-type grindstone forming device (100) is driven to rotate the rotary forming grindstone (27a) around the rotation shaft (27c).

研削装置(1)の砥石軸(16)に軸承された直径305mmの砥石車(17)の回転を開始し、次いで、この砥石車をX軸左方向に移動し、次いでY軸方向に下降させてドレス開始点位置にあるロータリー成形砥石(27a)に回転接触させて粗ドレス成形を開始する。   The rotation of the grinding wheel (17) having a diameter of 305 mm supported by the grinding wheel shaft (16) of the grinding apparatus (1) is started, and then the grinding wheel is moved leftward in the X axis and then lowered in the Y axial direction. Then, the rotary dressing grindstone (27a) at the dress start point position is brought into rotational contact to start coarse dressing.

ドレス加工プログラムに従ってサーボモータ(12m)駆動によりモーター軸(12c)を回転させることによりこのモーター軸(12c)の外周に取り付けられたウオーム(12b)が旋回軸(14)の外周に取り付けられたウオームホイール(12a)の歯筋と噛み合って旋回軸(14)を旋回させることにより成形砥石台(8)が旋回され、ロータリー成形砥石(27a)の旋回が追従して砥石車(17)の研削面の厚み方向の粗ドレッシング加工を行う。すなわち、サーボモータ(12m)の駆動によりモーター軸(12c)が回転し、従動回転するウオーム(12b)の歯筋とウオームホイール(12a)の歯筋が噛みあって回転し旋回軸(14)を旋回させる。この旋回軸(14)の旋回(X軸方向への移動)により成形砥石台(8)が旋回されるので噛み合うウオームホイール(12a)の歯筋の傾斜角度に追従して成形砥石(27a)の高さ(Y軸方向)位置(砥石車の
研削面に対し、成形砥石の刃先が接触する砥石成形点の位置のこと)および左右方向(X軸方向)位置が微少に変更されるので、旋回されるロータリー成形砥石(27a)は(X,Y)座標位置を微少に変えながら砥石車(17)の研削面廻りの形状に追従してドレス成形することが可能となる。
The worm (12b) attached to the outer periphery of the motor shaft (12c) by rotating the motor shaft (12c) by driving the servo motor (12m) according to the dressing program is attached to the outer periphery of the turning shaft (14). The grinding wheel base (8) is turned by meshing with the tooth traces of the wheel (12a) to turn the turning shaft (14), and the turning of the rotary forming wheel (27a) follows and the grinding surface of the grinding wheel (17). A rough dressing process in the thickness direction is performed. That is, the motor shaft (12c) is rotated by the drive of the servo motor (12m), the tooth traces of the worm (12b) and the tooth traces of the worm wheel (12a) are meshed with each other, and the swivel axis (14) is rotated. Turn. Since the forming wheel head (8) is turned by the turning (movement in the X-axis direction) of the turning shaft (14), the forming wheel (27a) follows the inclination angle of the tooth trace of the worm wheel (12a) to be engaged. Since the height (Y-axis direction) position (the position of the grinding wheel forming point where the cutting edge of the grinding wheel contacts the grinding surface of the grinding wheel) and the left-right direction (X-axis direction) position are slightly changed, turning The rotary forming grindstone (27a) to be dressed can follow the shape around the grinding surface of the grinding wheel (17) while slightly changing the (X, Y) coordinate position.

図4に示すロータリードレッサー装置(27)においては、旋回軸(14)の旋回角度が60度可能になっている。即ち、ロータリー成形砥石(27a)は前後方向(Z軸方向)に成形軸心(旋回軸心)がそれぞれ溝加工用砥石車の直径を含む垂直面の前後に対しプラスマイナス30度の角度旋回可能に構成されている。言い換えれば歯筋の噛み合せによるロータリー成形砥石刃先の溝加工用砥石車(17)の研削面に対する最大接触角度のマイナスポイントライン60度からマイナスポイントライン45度、マイナスポイントライン30度、谷部分のゼロポイントラインを経由するまではロータリー成形砥石(27a)の砥石車(17)に対する高さ位置は減少し、プラスポイントライン30度、プラスポイントライン45度、プラスポイントライン60度に到るまではロータリー成形砥石(27a)の砥石車(17)に対する高さ位置を増加させる。   In the rotary dresser device (27) shown in FIG. 4, the turning angle of the turning shaft (14) can be 60 degrees. In other words, the rotary forming grindstone (27a) can be turned in the front-rear direction (Z-axis direction) by an angle of plus or minus 30 degrees with respect to the front and rear of the vertical surface including the diameter of the grinding wheel for grooving. It is configured. In other words, the maximum contact angle with the grinding surface of the grinding wheel (17) of the rotary forming grindstone blade edge by meshing the tooth traces is 60 degrees minus point line 45 degrees, minus point line 30 degrees, trough part zero Until passing through the point line, the height position of the rotary forming wheel (27a) with respect to the grinding wheel (17) decreases, and until it reaches the plus point line 30 degrees, plus point line 45 degrees, plus point line 60 degrees, the rotary The height position of the forming wheel (27a) with respect to the grinding wheel (17) is increased.

ドレス加工プログラムを設計するに当たって、ドレス成形開始点位置を定めるのは、旋回軸の回転角度、正逆の旋回軸回転方向、旋回軸の回転停止時間を定めるのに重要な要因となる。砥石車(17)が先端楔状(尖角状)の溝切り成形用砥石車である場合、砥石車(17)直径方向下端と成形砥石(27a)直径方向下端が接触する点位置をドレス成形開始点位置とすると、成形砥石(27a)前側半分のドレッシング加工が終えたらサーボモータ(12m)の回転方向を逆にすることにより旋回軸(14)旋回方向を逆にし、ドレス成形開始点位置を通過させて成形砥石(27a)前側半分のドレッシング加工を行う。ドレス成形開始点位置を成形砥石(27a)が上昇可能なプラスポイント60度位置で砥石車(17)研削面の前側位置で接する点位置とすると旋回軸(14)の旋回方向は同一でよく、砥石車(17)研削面の前側ドレス成形開始点位置から砥石車(17)直径方向下端を通過し、砥石車(17)研削面の後ろ側ドレス成形終了点位置までの軌跡で成形砥石(27a)は粗ドレスッシング加工を行う。ウオームホイール(12a)歯筋の傾斜は、歯筋形状による。従って、図4では旋回角度がプラスマイナスポイント60度の例を示したが、ウオームおよびウオームホイールの歯筋形状によっては、プラスマイナスポイント45度、あるいは、プラスマイナスポイント30度の場合もありうる。   In designing the dressing program, determining the dress forming start point position is an important factor in determining the rotation angle of the pivot axis, the forward and reverse pivot axis rotation directions, and the rotation stop time of the pivot axis. When the grinding wheel (17) is a wedge-shaped (pointed-point) grooving grinding wheel, dress molding starts at the point where the grinding wheel (17) diameter lower end and the shaping wheel (27a) diameter lower end contact. Assuming the point position, when the dressing of the front half of the forming grindstone (27a) is completed, the turning direction of the servo motor (12m) is reversed to reverse the turning direction of the turning shaft (14) and pass the dress forming start point position. Then, the front half of the forming grindstone (27a) is dressed. If the dress forming start point position is a point position that contacts the front side position of the grinding wheel (17) at a plus point of 60 degrees where the forming wheel (27a) can rise, the turning direction of the turning shaft (14) may be the same, Grinding wheel (27a) along the trajectory from the grinding wheel (17) grinding surface front side dress molding starting point position to the grinding wheel (17) diameter lower end and to the rear dressing finishing point position of grinding wheel (17) grinding surface ) Performs rough dressing. The inclination of the worm wheel (12a) tooth trace depends on the shape of the tooth trace. Accordingly, FIG. 4 shows an example in which the turning angle is 60 degrees plus or minus point. However, depending on the shape of the tooth traces of the worm and the worm wheel, there may be a plus or minus point 45 degrees or a plus or minus point 30 degrees.

又、砥石車(17)がワークの平面研削(研磨)用の砥石外周面が直線状の砥石車であるときは、旋回軸(14)の旋回を停止し、砥石車(17)の方を砥石幅だけX軸方向に移動させつつドレッシング成形するドレス加工プログラムとする必要がある。   Further, when the grinding wheel (17) is a grinding wheel whose surface for grinding a surface of the workpiece is a linear grinding wheel, the turning of the turning shaft (14) is stopped, and the grinding wheel (17) is moved. It is necessary to provide a dressing program for performing dressing molding while moving the grinding wheel width in the X-axis direction.

ロータリー成形砥石(27a)による砥石車(17)の研削面の厚み方向の粗ドレッシング加工を終えたら砥石車(17)を上昇させ、次いで、砥石車(17)を右方向にk距離(100.75mm)移動させ、単石ダイヤモンド砥石(29a)の頭頂上方に位置(仕上げドレス開始待機位置)させる。一方、旋回軸(14)はサーボモータ(12m)により旋回されてドレス開始点待機位置に戻される。また、ロータリードレッサー装置(27)の駆動モーター(27m)は稼動を停止される。   After finishing the rough dressing process in the thickness direction of the grinding surface of the grinding wheel (17) by the rotary forming grinding wheel (27a), the grinding wheel (17) is raised, and then the grinding wheel (17) is moved to the k distance (100. 75 mm) and moved above the crown of the single stone diamond grindstone (29a) (finishing dress start standby position). On the other hand, the turning shaft (14) is turned by the servo motor (12m) and returned to the dress start point standby position. Further, the operation of the drive motor (27m) of the rotary dresser device (27) is stopped.

ドレス加工プログラムに従ってサーボモータ(12m)駆動によりモーター軸(12c)を回転させることによりこのモーター軸(12c)の外周に取り付けられたウオーム(12b)が旋回軸(14)の外周に取り付けられたウオームギアー(12a)の歯筋と噛み合って旋回軸(14)を旋回させることにより成形砥石台(8)が旋回され、単石ダイ
ヤモンド砥石(29a)の旋回が追従して砥石車(17)の研削面の厚み方向の仕上げドレッシング加工を行う。
The worm (12b) attached to the outer periphery of the motor shaft (12c) by rotating the motor shaft (12c) by driving the servo motor (12m) according to the dressing program is attached to the outer periphery of the turning shaft (14).

Finish dressing in the thickness direction of the surface.

単石ダイヤモンド砥石(29a)による砥石車(17)の研削面の厚み方向の仕上げドレッシング加工を終えたら砥石車(17)を上昇させ、次いで、砥石車(17)を左方向に100.75mm(k)移動させて粗ドレス成形開始待機位置に戻す。一方、旋回軸(14)はサーボモータ(12m)により旋回されてドレス開始点待機位置に戻される。   After finishing the dressing process in the thickness direction of the grinding surface of the grinding wheel (17) with the single stone diamond grinding wheel (29a), the grinding wheel (17) is raised, and then the grinding wheel (17) is moved 100.75 mm to the left ( k) Move to return to the rough dress forming start standby position. On the other hand, the turning shaft (14) is turned by the servo motor (12m) and returned to the dress start point standby position.
