Description

本発明は、カムシャフトやクランクシャフト等の非真円形ワークの研削方法及び研削装置に関する。 The present invention relates to a grinding method and a grinding apparatus for non-round workpieces such as camshafts and crankshafts.

この種のワークの研削法としては、ワークをクランプ装置で保持して回転させながら、ワークの軸芯と直交する面上でワークと回転砥石を相対移動させるのが一般的である。しかし、この方法は、１つの回転砥石で１つのワークを研削しているため、加工能率が良くない。そこで、図７に示すように、２つのワークａ,ｂを互いに平行に配置し、回転砥石ｅを、その軸芯Ｏをワークａ,ｂの軸芯Ｏを結ぶ線分ｃの垂直二等分線ｄに沿わせて移動させる方法が提案されている（特許文献１参照）。 As a grinding method for this kind of work, it is common to move the work and the rotating grindstone relative to each other on a surface orthogonal to the axis of the work while holding and rotating the work with a clamping device. However, since this method grinds one workpiece with one rotating grindstone, the processing efficiency is not good. Therefore, as shown in FIG. 7 , two works a and b are arranged in parallel to each other, and the rotating grindstone e is divided into two perpendicular bisects of a line segment c connecting the axis O of the works a and b. A method of moving along the line d has been proposed (see Patent Document 1).

しかし、この方法によれば、回転砥石ｅのワークａに対する切込力ｆのうち、ワークａの研削に寄与する成分は、両者の接点Ｐからワークａの中心ｏに向かう方向の分力（以下、研削有効成分という）ｆ１のみであり、接点Ｐにおける接線Ｔ方向の分力（以下、研削無効成分という）ｆ２はワークａの研削には全く寄与しない。この研削無効成分ｆ２が大きくなると、回転砥石ｅが振動し、加工精度が劣化する原因となる。   However, according to this method, the component contributing to the grinding of the workpiece a out of the cutting force f of the rotary grindstone e with respect to the workpiece a is a component force in the direction from the contact point P of both to the center o of the workpiece a (hereinafter referred to as “a”). , Which is referred to as an effective grinding component) f1, and a component force f2 in the tangential direction T (hereinafter referred to as an ineffective grinding component) f2 does not contribute to the grinding of the workpiece a at all. When the grinding ineffective component f2 is increased, the rotating grindstone e vibrates, which causes a deterioration in processing accuracy.

また、ワークａは回転砥石ｅの回転と同じ回転方向で研削（以下、アップカットという）され、ワークｂは回転砥石ｅの回転と逆回転方向で研削（以下、ダウンカットという）され、図７で分かるとおり、ダウンカットのワークｂは、アップカットのワークａと比較して、ワークｂの回転砥石ｅに対する研削抵抗が小さく、各ワークａ,ｂ間には研削抵抗に差があり、精度よく同様に加工するには難しい。   Further, the workpiece a is ground in the same rotational direction as the rotation of the rotating grindstone e (hereinafter referred to as upcut), and the workpiece b is ground in the direction opposite to the rotation of the rotating grindstone e (hereinafter referred to as downcut). As can be seen, the down-cut workpiece b has a smaller grinding resistance against the rotating wheel e of the workpiece b than the up-cut workpiece a, and there is a difference in the grinding resistance between the workpieces a and b. It is difficult to process as well.

本発明は、このような事情に鑑み、切込力の研削無効成分の発生による加工精度の劣化を防止できる研削方法及び研削装置を提供することを目的とする。 In view of such circumstances, an object of the present invention is to provide a grinding method and a grinding apparatus that can prevent deterioration in processing accuracy due to generation of a grinding ineffective component of a cutting force.

上記目的を達成するために本発明は、互いに平行に配置して回転される複数のワークを、その軸芯と直交する面上で回転研削工具に対して移動させて非真円形に研削する研削方法において、上記各ワークを、回転駆動源により同一方向に回転させながら、且つ、上記回転工具に対する上記各ワークの接する箇所の研削位相を同一に保った状態で上記ワークと回転研削工具との相対周速を上記ワークの研削位相に応じて変化させ、移動手段により該ワークの軸芯と上記回転研削工具の軸芯を通る線に沿って該各ワークを移動させながら該各ワークの研削を行うことを特徴とする。 In order to achieve the above object, the present invention provides a grinding method in which a plurality of workpieces arranged and rotated in parallel with each other are moved with respect to a rotary grinding tool on a surface perpendicular to the axis of the workpiece and ground into a non-round shape. In the method, the respective workpieces and the rotary grinding tool are relatively rotated while the respective workpieces are rotated in the same direction by a rotational drive source and the grinding phase at the portion where the respective workpieces are in contact with the rotary tool is kept the same. The peripheral speed is changed in accordance with the grinding phase of the workpiece, and the workpiece is ground while moving the workpiece along a line passing through the axis of the workpiece and the axis of the rotary grinding tool. It is characterized by that.

かかる構成によれば、回転研削工具に対して各ワークが両者の軸芯を結ぶ線上で接した状態で研削されるので、回転研削工具のワークに対する切込力の全てが研削有効成分となり、研削無効成分が発生しなく、回転研削工具の振動の発生を防止することができる。   According to such a configuration, since each workpiece is ground in contact with the rotary grinding tool on the line connecting both axes, the cutting force of the rotary grinding tool with respect to the workpiece becomes an effective grinding component. Ineffective components are not generated, and the vibration of the rotary grinding tool can be prevented.

また、各ワークの回転研削工具に対する相対周速が同一になるので、各ワークの相対周速を最適値に設定する際、相対周速の遅い方のワークに合わせる必要がなく、加工能率の低下を防止できる。 Also , since the relative peripheral speed of each workpiece with respect to the rotating grinding tool is the same, it is not necessary to match the workpiece with the slower relative peripheral speed when setting the relative peripheral speed of each workpiece to the optimum value, resulting in reduced machining efficiency. Can be prevented.

上記回転研削工具の周方向に上記ワークを等分配置するのが好ましい。   It is preferable to equally arrange the workpieces in the circumferential direction of the rotary grinding tool.

かかる構成によれば、各ワークに対する切込力の反力の合成ベクトルがゼロになり、回転研削工具の軸受荷重が軽減される。また、本発明に係る研削装置は、互いに平行に配置して回転される複数のワークを、非真円形に研削する研削装置において、回転研削工具を回転自在に支承する砥石台と、上記各ワークを同一方向に回転させつつ、該ワークをクランプするクランプ手段と、上記ワークを、該ワークの軸芯と上記回転研削工具の軸芯を通る線に沿って移動させながら研削を行う移動手段と、上記移動手段の移動量、上記クランプ手段の回転駆動を制御する制御手段とを有し、上記クランプ手段における上記ワークを回転させる回転駆動源は、上記ワークに応じて複数設けられてそれぞれ独立して制御され、上記制御手段は、上記クランプ手段により、上記回転工具に対する上記各ワークの接する箇所の研削位相を同一に保った状態で上記ワークと回転研削工具との相対周速を上記ワークの研削位相に応じて変化させて制御することを特徴とする。 According to such a configuration, the resultant vector of the reaction force of the cutting force with respect to each workpiece becomes zero, and the bearing load of the rotary grinding tool is reduced. In addition, a grinding apparatus according to the present invention includes a grinding wheel table that rotatably supports a rotary grinding tool in a grinding apparatus that grinds a plurality of workpieces arranged parallel to each other into a non-round shape, and each of the above-described workpieces. Clamping means for clamping the workpiece while rotating the workpiece in the same direction, moving means for performing grinding while moving the workpiece along a line passing through the axis of the workpiece and the axis of the rotary grinding tool, the amount of movement of the moving means, have a control means for controlling the rotation of the clamping means, the rotation drive source for rotating the workpiece in the clamping means, independently provided in plural according to the work The control means is configured so that the workpiece and the rotary grinding tool are maintained in a state in which the grinding phase of the part where each of the workpieces contacts the rotary tool is kept the same by the clamp means. The relative peripheral speed and controls is varied in accordance with the grinding phase of the work.

本発明によれば、１つの回転研削工具で複数のワークを同時に研削する際に、回転研削工具のワークに対する切込力の全てが研削有効成分となり、研削無効成分は発生しなくなるので、回転研削工具の振動発生がなくなり、加工精度の劣化を防止することができる。   According to the present invention, when a plurality of workpieces are simultaneously ground with a single rotary grinding tool, all of the cutting force of the rotary grinding tool on the workpiece becomes a grinding effective component and no grinding invalid component is generated. The occurrence of vibration of the tool is eliminated, and deterioration of machining accuracy can be prevented.

以下、本発明の実施形態を添付図面に基づいて詳細に説明する。図１は本実施の形態に係る研削方法を説明する図、図２は本実施の形態に係る研削装置の平面図である。 Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 is a diagram, Figure 2 illustrating the grinding method according to the present embodiment is a plan view of a grinding apparatus according to the present embodiment.

図２において、１は基台で、この基台１には一対のスライドテーブル２を矢印Ｘ方向に移動自在に設置してある。基台１の中央部でスライドテーブル２,２の間には、ガイドレール３を固設してある。ガイドレール３には、砥石台４をスライドテーブル２の移動方向Ｘと直交する回転軸方向Ｚに移動自在に設置してある。砥石台４は回転研削工具としての砥石５を備えている。各スライドテーブル２,２にはクランプ装置６が設けてあり、この装置６でワーク７を保持してモータ８で回転駆動させるように構成してある。   In FIG. 2, reference numeral 1 denotes a base, and a pair of slide tables 2 are installed on the base 1 so as to be movable in the arrow X direction. A guide rail 3 is fixed between the slide tables 2 and 2 at the center of the base 1. On the guide rail 3, a grindstone table 4 is installed so as to be movable in a rotation axis direction Z perpendicular to the movement direction X of the slide table 2. The grindstone table 4 includes a grindstone 5 as a rotary grinding tool. Each slide table 2, 2 is provided with a clamp device 6, which is configured to hold a work 7 with this device 6 and to rotate it with a motor 8.

この研削装置では、各ワーク７,７は砥石５の周方向二等分箇所に接する状態で同時研削される（図１参照）。つまり、ワーク７,７は、その軸芯Ｏと直交する面上であって、砥石５とワーク７の軸芯Ｏを結ぶ線Ｌに沿って移動する。また、ワーク７,７は研削位相を同一に保った状態で同一方向に回転する。ここで、研削位相とは、ワーク７の頂点Ｐと軸芯Ｏを挟んで反対側に位置する点Ｐｏを基準とした場合、ワーク７の砥石５に対する接点の、軸芯Ｏから見た方位角のことをいう。   In this grinding apparatus, the workpieces 7 and 7 are simultaneously ground while being in contact with the circumferentially bisected portion of the grindstone 5 (see FIG. 1). That is, the workpieces 7 and 7 move on a plane orthogonal to the axis O and move along a line L connecting the grindstone 5 and the axis O of the workpiece 7. Further, the workpieces 7 and 7 rotate in the same direction while maintaining the same grinding phase. Here, the grinding phase refers to the azimuth angle of the contact point of the workpiece 7 with respect to the grindstone 5 as viewed from the axis O when the vertex Po located on the opposite side across the vertex P of the workpiece 7 and the axis O is used as a reference. I mean.

図３はカムシャフトとしてのワーク７のプロフィールを示す図で、カムシャフト７は、軸となるベース円部７ａと、内燃機関の弁をリフトアップする為のリフト部７ｂとからなり、このリフト部７ｂの頂点がカムシャフト７の頂点Ｐである。いま、頂点Ｐと軸芯Ｏを挟んで反対側に位置する点Ｐｏを研削位相０度、頂点Ｐを研削位相１８０度とすると、ワーク７を保持しているクランプ装置６は、回転駆動するモータ８によって、ワーク７の砥石５に対する接点の軸芯方位角（研削位相）に応じて変化する回転数で、回転駆動される。研削位相０度のときのワーク７の回転数を１００（相対値）とした場合、リフト部、特に頂点Ｐ（研削位相１８０度）付近は、ワーク７の回転数を、例えば５０程度（相対値）に落とした方がよいことが分かっている。モータ８は、図示しないワーク回転制御機器で研削位相をセンシングし、研削位相に応じた回転数になるように制御されている。   FIG. 3 is a view showing a profile of a work 7 as a camshaft. The camshaft 7 includes a base circle portion 7a serving as a shaft and a lift portion 7b for lifting up a valve of the internal combustion engine. The vertex 7b is the vertex P of the camshaft 7. Now, assuming that the point Po located on the opposite side across the vertex P and the axis O is a grinding phase of 0 degrees and the vertex P is a grinding phase of 180 degrees, the clamping device 6 holding the workpiece 7 is a motor that rotates. 8, the workpiece 7 is rotationally driven at a rotational speed that changes in accordance with the axial azimuth (grinding phase) of the contact point of the work 7 with respect to the grindstone 5. When the rotational speed of the workpiece 7 when the grinding phase is 0 degree is 100 (relative value), the rotational speed of the workpiece 7 is about 50 (relative value), for example, in the vicinity of the lift portion, particularly at the apex P (grinding phase 180 degrees). ) Is known to be dropped. The motor 8 senses the grinding phase with a workpiece rotation control device (not shown) and is controlled so as to have a rotational speed corresponding to the grinding phase.

ところで、ワーク７の軸芯Ｏと直交する面上でワーク７と砥石５とを相対移動させればよいのであるから、図４に示すように、砥石５の直径を変化させるようにしてもよい。ここで、砥石５は本体部５ａと可動部５ｂからなり、可動部５ｂをアクチュエータ（移動手段）１００で半径方向に沿って往復動させるようにしてある。このようにすると、ワーク７を砥石５に対して接近・離反させる移動機構が不要になり、一対のスライドテーブル２の省略によりコンパクト化が可能になる。   Incidentally, since the work 7 and the grindstone 5 have only to be relatively moved on a surface orthogonal to the axis O of the work 7, the diameter of the grindstone 5 may be changed as shown in FIG. . Here, the grindstone 5 includes a main body portion 5a and a movable portion 5b, and the movable portion 5b is reciprocated along the radial direction by an actuator (moving means) 100. If it does in this way, the movement mechanism which makes the workpiece | work 7 approach / separate with respect to the grindstone 5 will become unnecessary, and compactization will be attained by abbreviate | omitting a pair of slide table 2. FIG.

ワーク７,７の同時研削に際しては、砥石５とワーク７,７を回転させながら、砥石５に対してワーク７,７を接近・離反を繰り返すように、図２の矢印Ｘ方向に移動自在なスライドテーブル（接動機構）２を移動させる。このスライドテーブル２は、図示しない接動機構を移動制御する制御機器によって、その移動位置がセンシングされ、移動量の制御が行われる。つまり、ワーク７,７は、その移動量を研削位相に応じて変化させることによって、非真円形に研削される。   When the workpieces 7 and 7 are simultaneously ground, the workpieces 7 and 7 can be moved in the direction of the arrow X in FIG. 2 so that the workpieces 7 and 7 are repeatedly moved toward and away from the grindstone 5 while rotating the grindstone 5 and the workpieces 7 and 7. The slide table (contact mechanism) 2 is moved. The moving position of the slide table 2 is sensed by a control device that controls the movement of a contact mechanism (not shown), and the amount of movement is controlled. That is, the workpieces 7 and 7 are ground into a non-round shape by changing the movement amount according to the grinding phase.

その際、各ワーク７,７は砥石５に対して両者の軸芯Ｏを結ぶ線Ｌ上で接した状態で研削されるので、砥石５のワーク７に対する切込力ｆの全てが研削有効成分となり、研削無効成分は発生しなる。このため、砥石５の振動発生がなくなり、加工精度の劣化を防止することができる。   At that time, since the workpieces 7 and 7 are ground in a state where they are in contact with the grindstone 5 on a line L connecting both the axes O, the cutting force f of the grindstone 5 to the workpiece 7 is all effective grinding components. Thus, an ineffective grinding component is generated. For this reason, generation | occurrence | production of the vibration of the grindstone 5 is lose | eliminated, and deterioration of a processing precision can be prevented.

ところで、加工精度を良くするためには、前述のように、砥石５とワーク７の相対周速をワーク７の研削位相に応じた最適な値にするのが好ましい。そこで、各ワーク７,７をその研削位相を同一に保った状態で、砥石５の回転方向と同一方向に回転させることによって、各ワーク７,７の砥石５に対する相対周速を同一にしている。前述のダウンカットなしの、アップカットのみの加工となり、各ワーク７,７の砥石５に対する研削抵抗差がなくなるのでよい。   By the way, in order to improve the processing accuracy, it is preferable to set the relative peripheral speed of the grindstone 5 and the workpiece 7 to an optimum value corresponding to the grinding phase of the workpiece 7 as described above. Therefore, the relative peripheral speeds of the workpieces 7 and 7 with respect to the grindstone 5 are made the same by rotating the workpieces 7 and 7 in the same direction as the rotation direction of the grindstone 5 while maintaining the same grinding phase. . Only the up-cut is performed without the down-cut described above, and the difference in grinding resistance between the workpieces 7 and 7 with respect to the grindstone 5 may be eliminated.

従来から知られている研削装置、例えば、特開平２００１−３１５０４８号公報に示すような両頭研削盤においては、ワークの一方向側に砥石台が２基備わっており、一方の砥石があるカムのカムプロフィールを研削しているとき、同時に他方の砥石が他のカムのカムプロフィールを研削することになる。例えば、４気筒ＤＯＨＣ内燃機関で使用するカムシャフトは、合計８個のカムのプロフィールを研削することになる。この場合、同じ気筒内のカムは配設ピッチが小さいため、前述の両頭研削盤で研削すると、異なる気筒のカムを研削せざるをえず、研削位相を同一にすることはできない。   In a conventionally known grinding apparatus, for example, a double-headed grinding machine as shown in Japanese Patent Application Laid-Open No. 2001-315048, two grinding wheel platforms are provided on one side of a workpiece, and a cam with one grinding wheel is provided. When grinding the cam profile, the other wheel simultaneously grinds the cam profile of the other cam. For example, a camshaft used in a 4-cylinder DOHC internal combustion engine will grind the profile of a total of 8 cams. In this case, since the cams in the same cylinder have a small arrangement pitch, if the above-mentioned double-head grinding machine is used for grinding, the cams in different cylinders must be ground, and the grinding phase cannot be made the same.

このため、ワークの相対周速を最適値に設定する場合、相対周速の遅い方のカムのプロフィールに合わせる必要があり、砥石の台数分に相当する加工能率の向上を期待することはできない。砥石の台数が２の場合、加工能率は１.２〜１.４倍になることが分かっている。これに対して、本実施形態の場合、各ワーク７,７の砥石５に対する相対周速を同一にしているので、相対周速の遅い方のワーク７に相対周速を合わせる必要がなく、加工能率の低下を防止することができる。つまり、ワーク７を保持するクランプ装置６の台数に比例して加工能力を向上させることができる。ただし、砥石５の両側にクランプ装置６を配置するだけでよいので、設置スペースをあまり大きくしなくても済む。   For this reason, when setting the relative peripheral speed of the workpiece to the optimum value, it is necessary to match the profile of the cam having the slower relative peripheral speed, and it is not possible to expect an improvement in machining efficiency corresponding to the number of grindstones. It is known that when the number of grindstones is 2, the machining efficiency is 1.2 to 1.4 times. On the other hand, in this embodiment, since the relative peripheral speeds of the workpieces 7 and 7 with respect to the grindstone 5 are the same, it is not necessary to match the relative peripheral speed to the work 7 having the slower relative peripheral speed, and machining A reduction in efficiency can be prevented. That is, the machining capability can be improved in proportion to the number of clamping devices 6 that hold the workpiece 7. However, since it is only necessary to dispose the clamping device 6 on both sides of the grindstone 5, the installation space does not have to be increased.

なお、一対のクランプ装置６,６は、それぞれ独立したスライドテーブル２,２に設けられ、且つ、それぞれ独立したモータ８,８によって、各ワーク７,７の砥石５に対する接点の軸芯方位角（研削位相）に応じて変化する回転数で回転駆動されるので、ワーク７,７は異機種混合でもよく、フレキシブルに加工することができる。   The pair of clamping devices 6 and 6 are provided on the independent slide tables 2 and 2, respectively, and the axis azimuth of the contact point of the workpieces 7 and 7 with respect to the grindstone 5 by the independent motors 8 and 8 ( The workpieces 7 and 7 may be of different types and can be processed flexibly.

また、２つのワーク７,７を砥石５の周方向に等分箇所に配置してあるので、各ワーク７,７に対する切込力ｆの反力の合成ベクトルがゼロになり、砥石５の軸受荷重を軽減することができる。ワーク７の数が３つの場合には、図５に示すようにワーク７を砥石５に対して周方向に３等分配置すればよい。なお、砥石５の軸受荷重をあまり考慮する必要がない場合には、図６に示すようにワーク７を等分配置しなくてもよい。   In addition, since the two workpieces 7 and 7 are equally divided in the circumferential direction of the grindstone 5, the resultant vector of the reaction force of the cutting force f with respect to each workpiece 7 and 7 becomes zero, and the bearing of the grindstone 5 The load can be reduced. When the number of workpieces 7 is three, the workpieces 7 may be arranged in three equal parts in the circumferential direction with respect to the grindstone 5 as shown in FIG. In addition, when it is not necessary to consider the bearing load of the grindstone 5 very much, it is not necessary to arrange | position the workpiece | work 7 equally as shown in FIG.
