【0005】[0005]
この課題を解決するために本考案の構成では、冒頭に述べた形式の研削盤にお いて、内面研削用といし軸がといし車中心点を中心にして鉛直平面において、研 削盤に入力されたプログラムを介して所望の角度位置に自動的に旋回可能であり 、かつといしの目直しを目的として、水平位置において、工作主軸台の横に配置 された成形ローラのそばを通過可能であるようにした。 In order to solve this problem, in the structure of the present invention, in the grinding machine of the type described at the beginning, the grinding wheel for internal grinding is input to the grinding machine in the vertical plane centering on the center of the grinding wheel. It is possible to automatically swivel to a desired angular position via a programmed program and to pass by a forming roller located next to the machine headstock in a horizontal position for the purpose of dressing the grinding wheel. I did.
【0006】[0006]

In the horizontal position, internal grinding takes place, and in this position the grinding wheel can be dressed on the forming rollers arranged next to the machine headstock. Therefore, it is not necessary to adjust the dressing device for screw grinding to the screw pitch angle as well.
【0007】[0007]
次に図面につき本考案の実施の形態を説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.
【0008】 研削盤テーブル1には工作主軸台2を保持する横方向往復台3と、内面研削用 といし軸4を保持する研削テーブル5とが配置されている。さらに、2研削ユニ ットとして構成された円筒研削装置6が設けられており、該円筒研削装置の往復 台7は矢印X2の方向において可動であり、往復台7aは矢印Z2の方向におい て送り可能である。またX1で横方向往復台3の送り方向が示され、Z1で内面 研削用といし軸4の送り方向が示され、矢印A,C,S1,S2及びS3で内面 研削用といし軸4、円筒研削用といし軸8、工作主軸及び目直しローラ9の回転 ないし旋回方向がそれぞれ示されている。On the grinding machine table 1, there are arranged a transverse carriage 3 which holds a work headstock 2 and a grinding table 5 which holds an internal grinding wheel spindle 4. Furthermore, a cylindrical grinding device 6 configured as a two-grinding unit is provided, the carriage 7 of the cylindrical grinding device is movable in the direction of arrow X 2 , and the carriage 7 a is placed in the direction of arrow Z 2 . Can be sent. Further, X 1 indicates the feed direction of the lateral carriage 3, Z 1 indicates the feed direction of the grinding wheel shaft 4 for inner surface grinding, and arrows A, C, S 1 , S 2 and S 3 indicate for inner surface grinding. The rotational or swivel directions of the wheel spindle 4, the cylindrical grinding wheel spindle 8, the work spindle and the dressing roller 9 are shown respectively.
【0009】 作業経過は以下の通りである: (a) 円形面研削の場合には内面研削装置と円筒研削装置とが同時に作業を 行う。それというのはX1軸線が内面及び円筒研削ユニットのための送り軸線と して働くからである。The work progress is as follows: (a) In the case of circular surface grinding, the inner surface grinding machine and the cylindrical grinding machine work simultaneously. This is because the X 1 axis serves as the feed axis for the inner surface and the cylindrical grinding unit.
【0010】 内面研削時における精度に対する要求はしばしば円筒研削時におけるよりも高 いので、荒研削と仕上研削とから成る同時研削サイクル内で外径は最終寸法に研 削されることができ、次いで円筒研削ユニットは待期位置に引き戻される。Since the accuracy requirements for internal grinding are often higher than for cylindrical grinding, the outer diameter can be ground to the final dimensions in a simultaneous grinding cycle consisting of rough grinding and finish grinding, and then The cylindrical grinding unit is pulled back to the waiting position.
【0011】 内面研削用のといし車は目直しローラ9において中間目直しされ、この場合目 直しローラ9が固定されている工作主軸台2及び内面研削用のといし軸4は適当 に移動させられる。入力された距離/時間ダイヤグラムを介して任意の研削サイ クル(軸方向研削、プランジ研削、斜めプランジ研削、ないし平面研削)はほと んど制限されることなく自由に組み合わせることができる。内面研削用といし軸 は円形面研削中、といし車(ねじ研削用といし車を含む)の形削り中並びに自動 的なといし車交換中に水平な角度位置を占めている。The grinding wheel for internal grinding is intermediately dressed by a dressing roller 9, and in this case, the work headstock 2 to which the dressing roller 9 is fixed and the grinding wheel 4 for internal grinding are appropriately moved. To be Any grinding cycle (axial grinding, plunge grinding, oblique plunge grinding or even surface grinding) can be freely combined via the entered distance / time diagram, with almost no restrictions. The grinding wheel for internal grinding occupies a horizontal angular position during circular grinding, during shaping of grinding wheels (including grinding wheels for thread grinding) and during automatic wheel replacement.
【0012】 (b) ねじ研削のためには内面研削用といし軸4はプログラミングされたピ ッチ角にもたらされる。A軸線を介して行われるこの角度調節つまり鉛直方向に おける角度調節は、目直しからの引戻し動作中に行われる。ねじ研削サイクルの 経過中には荒研削サイクルに1回又は複数回の仕上研削サイクルが続く。荒研削 の前ないし仕上研削の前にといし車にもたらされる形状はその都度異なっている 。目直し、内面研削用といし車の角度調節及び自動的なといし車交換は、研削盤 に入力されたプログラムを介して自動的に行われる。(B) For thread grinding, the inner grinding wheel spindle 4 is brought to the programmed pitch angle. This angle adjustment, that is, the angle adjustment in the vertical direction, which is performed via the A axis, is performed during the pullback operation from the dressing. The rough grinding cycle is followed by one or more finishing grinding cycles during the course of the thread grinding cycle. The shape brought to the wheel before rough grinding or finish grinding is different in each case. Adjusting and adjusting the angle of the grinding wheel for internal grinding and automatic grinding wheel replacement are performed automatically through the program entered in the grinding machine.
【0013】 図2には自動的な旋回装置が略示されている。内面研削用のといし軸4は、と いし車中心に位置する旋回点10を中心にしてサーボモータ11及びボールロー ラスピンドル12を用いて、A軸線方向における0位置から破線で示されている 所望の角度位置へと旋回させられる。FIG. 2 schematically shows an automatic turning device. The grinding wheel shaft 4 for inner surface grinding is shown by a broken line from the 0 position in the A axis direction by using a servo motor 11 and a ball roller spindle 12 around a turning point 10 located at the center of the grinding wheel. Is swung to the angular position of.
【0014】 図3は水平位置における内面研削用といし軸の研削動作を示し、図4は角度を つけられた、つまり水平位置から幾分旋回させられたといし軸の研削動作を示し 、図5は研削軸マガジン13の正面図である。FIG. 3 shows the grinding operation of the wheel shaft for internal grinding in the horizontal position, and FIG. 4 shows the grinding operation of the wheel shaft at an angled, that is to say slightly swiveled from the horizontal position, FIG. FIG. 3 is a front view of the grinding shaft magazine 13.
【0015】 種々異なった工作物のためには種々様々なといしが必要である。といしの交換 は研削軸マガジン13を介して自動的に行われ、この研削軸マガジンは内面研削 装置の上に固定されていて研削軸交換のために油圧によってといし軸中心に向っ て下げられることができる。研削軸マガジンにおける装着は研削盤制御装置にお いて記憶され、かつ適当に制御されることができる。A variety of wheels are required for different workpieces.
