Description

本発明は、例えばカム軸またはクランク軸の軸受けまたはジャーナルのような、１つの軸の中心にある回転面を研磨するための同時研磨機に関する。   The present invention relates to a simultaneous polishing machine for polishing a rotating surface in the center of one shaft, for example a camshaft or crankshaft bearing or journal.

特許文献１から、研磨ディスクセットを有する、クランク軸の多数の軸受部を同時に研磨するための研磨機が公知である。
その際、この研磨ディスクセットに相対して位置して、このクランク軸の他方の側に、個別研磨ディスクが、支持要素座部の研磨のために設けられている。従って、付加的に、１つの支持要素座部が研磨される。
この仕上げの後、この個別研磨ディスクは後退され、且つ、支持要素が当接される。引き続いて、軸受部は、研磨ディスクセットでもって、完成した状態に研磨される。 From Patent Document 1, a polishing machine having a polishing disk set for simultaneously polishing a large number of bearing portions of a crankshaft is known.
In this case, an individual polishing disk is provided for polishing the support element seat on the other side of the crankshaft, positioned relative to the polishing disk set. Thus, additionally, one support element seat is ground.
After this finishing, the individual abrasive disc is retracted and the support element is abutted. Subsequently, the bearing portion is polished to a completed state with a polishing disk set.

従って本発明の課題は、冒頭に記載した様式の研磨機を発展させることであり、このことでもって、加工材料のための加工時間が従来技術に比して低減される。   The object of the present invention is therefore to develop a polishing machine of the type described at the outset, which reduces the processing time for the processing material compared to the prior art.

この課題は、請求項１の特徴を有する研磨機によって解決される。有利な実施形態は、従属請求項の対象である。   This problem is solved by a polishing machine having the features of claim 1. Advantageous embodiments are the subject matter of the dependent claims.

本発明の有利な観点に従い、研磨されるべき回転面は、２つの研磨ディスクセットに分配され、且つ、これら研磨ディスクセットが、軸の相対して位置している側に設けられており、従って、この軸に対して作用する、これら研磨力の法線力成分は、相互に相殺される。
更に、支持要素が設けられており、この支持要素が、研磨の際に、研磨ディスクセットと共に、加工材料へと送られ（zugestellt）、且つ、接線方向において加工材料に対して作用する切削力（Zerspankraefte）が収容される。その際、この支持要素のために、如何なる座部（Sitze）も予研磨される必要は無い。 In accordance with an advantageous aspect of the present invention, the rotating surface to be polished is distributed between two polishing disk sets, and these polishing disk sets are provided on oppositely positioned sides of the shaft, and therefore The normal force components of these polishing forces acting on this axis cancel each other.
In addition, a support element is provided, which, during polishing, together with the abrasive disc set is sent to the work material (zugestellt) and a cutting force acting on the work material in the tangential direction ( Zerspankraefte) is housed. In doing so, no Sitze need be pre-polished for this support element.

次に、本発明を、実施例に基づいて詳しく説明する。   Next, the present invention will be described in detail based on examples.

図１に従う同時研磨機は、加工材料スピンドル１、および、押し台２を、軸（加工材料）３の中心における締付けおよび駆動のために有している。これら軸３の加工のために、２つの、研磨スピンドル台６、６′が設けられている。これら研磨スピンドル台は、機械フレーム７における、水平方向移動台５、５′、および垂直方向移動台４、４′を介して、案内装置８の上を移動可能である。
これら研磨スピンドル台６、６′は、Ｘ軸線方向に、反対の方向内において、この軸３へと送られ、従って、この軸３に対して半径方向に作用する、これら研磨力の法線力成分は、相互に相殺される。
Ｚ方向内における、垂直方向移動台４、４′の駆動は、ボールローラスピンドルおよびモータ９を介して行われる。類似して、同様に、加工材料スピンドル１も、モータ９′を介して、位置移動可能に、機械フレームに設けられている。 The simultaneous polishing machine according to FIG. 1 has a work material spindle 1 and a push table 2 for clamping and driving at the center of a shaft (work material) 3. For the machining of these shafts 3, two grinding spindle stands 6, 6 'are provided. These polishing spindle tables are movable on the guide device 8 via horizontal moving tables 5, 5 ′ and vertical moving tables 4, 4 ′ in the machine frame 7.
These polishing spindle stands 6, 6 'are fed to this shaft 3 in the opposite direction in the X-axis direction, and thus the normal force of these polishing forces acting radially on this shaft 3 The components cancel each other out.
The vertical movement tables 4 and 4 ′ are driven in the Z direction through a ball roller spindle and a motor 9. Similarly, the work material spindle 1 is also provided in the machine frame so as to be movable via a motor 9 '.

図１内において、軸３として、クランク軸３が図示されている。
このクランク軸は、同時に、２つの研磨ディスクセット１０、１０′でもって加工される。
これら両方の研磨ディスクセット１０、１０′は、それぞれに、多数の個別研磨ディスク１３から構成されている。従って、全ての、研磨されるべき、中心にある回転面１２は、唯一の加工ステップ内において、完成した状態に研磨され得る。
ここで図示されたクランク軸３の場合、中間軸受部、ジャーナル１５、および、フランジ外周面１６が具体的である。その際、これら個別研磨ディスク１３の幅、および、これら個別研磨ディスクの相互の間隔は、このクランク軸の上での、回転面１２の間隔および寸法に適合されている。 In FIG. 1, a crankshaft 3 is shown as the shaft 3.
This crankshaft is simultaneously machined with two abrasive disc sets 10, 10 '.
Both of these abrasive disc sets 10, 10 ′ are each composed of a number of individual abrasive discs 13. Thus, all of the central rotating surface 12 to be polished can be polished to a finished state within a single processing step.
In the case of the crankshaft 3 shown here, the intermediate bearing portion, the journal 15, and the flange outer peripheral surface 16 are specific. In this case, the width of the individual polishing disks 13 and the distance between the individual polishing disks are adapted to the distance and dimensions of the rotating surface 12 on the crankshaft.

スピンドル軸線１４、１４′の方向内における、研磨ディスクセット１０、１０′の互い違いの位置ずれにもかかわらず、この軸３の撓みは、無視可能である。何故ならば、
これら研磨ディスクセット１０、１０′が、相対して位置している側で、この軸３に対して作用するからである。
同じ効果は、極度に曲げに敏感な軸３のために、更に、加工されるべき回転面１２よりも多数の個別研磨ディスク１３が設けられていることによって補強され得る。 Despite the staggered misalignment of the abrasive disc set 10, 10 'in the direction of the spindle axis 14, 14', this deflection of the shaft 3 is negligible. because,
This is because the polishing disk sets 10 and 10 'act on the shaft 3 on the side where they are positioned relative to each other.
The same effect can be reinforced by the provision of a greater number of individual abrasive discs 13 for the extremely bend-sensitive shaft 3 than the rotating surface 12 to be machined.

図２は、請求項３に従う配設に関している。ここで、ほぼ軸３の中間において、１つの回転面１２において、２つの個別研磨ディスク１３、１３′が、同時に係合している。
図３は、請求項４に従う配設を示しており、その際、２つの回転面１２において、２つの個別研磨ディスク１３、１３′が、同時に係合している。 FIG. 2 relates to an arrangement according to claim 3. Here, approximately in the middle of the shaft 3, the two individual polishing disks 13, 13 ′ are simultaneously engaged on one rotating surface 12.
FIG. 3 shows an arrangement according to claim 4, in which two individual abrasive discs 13, 13 ′ are simultaneously engaged on the two rotating surfaces 12.

図４および５内において、カム軸の加工が図示されている。
この図４は、請求項５の特徴に相応しており、その際、軸３の全ての回転面１２において、２つの個別研磨ディスク１３、１３′が、同時に係合している。要するに、図５は、請求項６に従う配設を図示している。 In FIGS. 4 and 5, the machining of the camshaft is illustrated.
FIG. 4 corresponds to the features of claim 5, in which two individual abrasive discs 13, 13 ′ are engaged simultaneously on all rotating surfaces 12 of the shaft 3. In short, FIG. 5 illustrates an arrangement according to claim 6.

図６内において、支持要素１７の配設が図示され
ている。
この支持要素は、研磨の際に、個別研磨ディスク１３、１３′と共に同時に送られ、その際、接線方向において加工材料に対して作用する切削力が相殺される（kompensiert）。これら個別研磨ディスク１３，１３′が、Ｘ軸線方向に、反対の方向内において送られる間、この支持要素１７はＹ方向において送られる。 In FIG. 6, the arrangement of the support elements 17 is illustrated.
This support element is simultaneously fed with the individual abrasive discs 13, 13 ′ during polishing, whereby the cutting forces acting on the workpiece in the tangential direction are offset (kompensiert). This support element 17 is fed in the Y direction while these individual abrasive discs 13, 13 'are fed in the opposite direction, in the X-axis direction.
