Description
【発明の詳細な説明】 本発明は自動加圧型遊星研磨機に関する。[Detailed description of the invention] The present invention relates to an automatic pressure type planetary polishing machine.
近年研磨に利用されている遊星研磨機は、第1図に示す
ように、二個の同一の大きさの回転砥石111,112
の最も接近し合う位置に断面が円形の被研磨物2を砥石
111.112双方によって適当に押圧しながら保持し
、回転砥石111.112は各中心回転軸121.12
2が両者の中心点21(被研磨物2の円形断面の中心点
と一致する。)を中心に回転することに伴って公転し、
これによって、被研磨物2を一様に研磨することを特徴
とするものである(第1図では回転砥石 111゜11
2の回転軸121.122と共に回転する方向を黒矢印

す。)。As shown in Fig. 1, a planetary polishing machine that has been used for polishing in recent years uses two rotating grindstones 111 and 112 of the same size.
The object to be polished 2, which has a circular cross section, is held at the closest position by both grinding wheels 111 and 112 while being appropriately pressed.
2 revolves around their center point 21 (which coincides with the center point of the circular cross section of the object to be polished 2),
As a result, the object to be polished 2 is uniformly polished (in Fig. 1, the rotating grindstone 111°11
The direction of rotation with the rotating shafts 121 and 122 of 2 is indicated by a black arrow c''), and the direction of revolution is indicated by a white arrow c5).
、しかし、従来の遊星研磨機では回転軸121゜122
の中心点22からの距離が一定であるために、研磨に伴
い回転砥石111.112の外周部が摩滅し、これによ
って回転砥石の半径が漸次減少し、被研磨物2を適当な
抑圧によって保持しつつ研磨することが不可能となる。However, in the conventional planetary polishing machine, the rotation axis is 121°122
Since the distance from the center point 22 is constant, the outer peripheries of the rotating grindstones 111 and 112 are worn out during polishing, and as a result, the radius of the rotating grindstones gradually decreases, and the object 2 to be polished is held with appropriate pressure. It becomes impossible to polish while polishing.
このために、一時研磨機の作動を停止して、回転軸12
1.122の中心点22からの距離を調整するという煩
雑な作業が不可欠であるが、これによっても調整直後の
回転砥石の半径は漸次減少してゆくので、一様な研磨を
行うことは困難であった・
本発明は、このような点を克服することを目的とするも
のであるが、これは回転軸121.122に両者の中心
位置22の方向へ一定の相等しい力を作用させると同時
に回転軸121.122を該中心位置22へ移動可能と
することによって達成できる。For this purpose, the operation of the polishing machine is temporarily stopped and the rotating shaft 12 is
1. The complicated work of adjusting the distance from the center point 22 of 122 is essential, but the radius of the whetstone gradually decreases immediately after adjustment, making it difficult to perform uniform polishing. The purpose of the present invention is to overcome this problem by applying a constant and equal force to the rotating shafts 121 and 122 in the direction of the center position 22 of both. This can be achieved by simultaneously allowing the rotating shafts 121 and 122 to move to the center position 22.
何故ならば、このような構成によって、たとえ研磨に伴
って回転砥石121.122の半径が減少しても、回転
軸121.122が前記の力によって減少した半径に相
当する距離だけ、中心位置22の方向に移動し、これに
よって相変らず、一定の押圧力で被研磨物2を保持する
ことになるからである。This is because, with such a configuration, even if the radius of the rotary grindstone 121, 122 decreases due to polishing, the rotation axis 121, 122 can move from the center position 22 by a distance corresponding to the radius decreased by the aforementioned force. This is because the object to be polished 2 is held with a constant pressing force.
又本発明はこのような課題を解決したものであるが、回
転軸121.122を中心位置方向に移動させる駆動力

ことを特色とするものである。The present invention has solved this problem, and is characterized in that the driving force source for moving the rotating shafts 121 and 122 in the direction of the center position is fixed instead of rotating together with the rotation @ 121 and 122. It is something.

軸121.1.22は中心位置22の方向に移動する。The rotational movement ring 34 transfers the pressing force transmitted from the rod 31 to the rod 351.3521 rotation linkage 361.36.
2. Rotating shaft 121.1 via crank 371.372
In addition to the 22 supports 131.132, this causes the axis of rotation 121.1.22 to move in the direction of the central position 22.

ことによって調整する。Here, the moving speed of the rotating shafts 121, 122 to the center position 22 is determined by the motor (
Adjustment is made by controlling the number of pulses delivered to the pulse motor 4 per unit time so that the rotational torque of the motor (not shown) is constant.
このように調整する理由は、回転砥石 111.112

被研磨物に対する抑圧力は、前記トルクに比例すること
になる以上、前記押圧力を一定とするためには、回転に
要するトルクが一定となっている状態を維持することが
必要とされるからである。The reason for adjusting in this way is that the rotating whetstone 111.112
The magnitude of the pressing force against the object to be polished is proportional to the kinetic frictional force accompanying rotation, while the torque required to rotate the rotating grindstone is proportional to the kinetic frictional force received from the object to be polished. This is because force is proportional to the torque, so in order to keep the pressing force constant, it is necessary to maintain a constant torque required for rotation.
回転トルクは回転エネルギーを角速度で割ることによっ
て得られるので消費電力と回転数とを測定することによ
って回転トルクをほぼ検知することができる。Since rotational torque is obtained by dividing rotational energy by angular velocity, rotational torque can be approximately detected by measuring power consumption and rotational speed.

る通常の自動制御方式によって達成される。In addition, the method of controlling the number of pulses delivered to the pulse motor so as to keep the rotational torque constant is to feed back the difference between the reference value of torque and the actually detected rotational torque, and to deliver this. This is accomplished by a so-called conventional automatic control method that converts the number of pulses into increases and decreases.

ない。With the planetary polishing machine of the present invention configured as described above, even if the rotating grinding wheels become worn out, the complicated work of stopping the operation and adjusting the distance between the rotating grinding stones is unnecessary, and the object to be polished is always maintained at a constant level. Since it is supported by the pressing force of ゛, there is no need to worry about uneven polishing due to wear of the rotating grindstone.
又押圧力を生じさせる駆動力源(例えばシリンダー3又
は、パルスモータ−4)を回転軸121.122 と共
に公転せずに固定させているので該駆動力源が破損する
恐れもなく、機械全体の寿命を維持することができる。In addition, since the driving power source (for example, cylinder 3 or pulse motor 4) that generates the pressing force is fixed without rotating together with the rotating shaft 121, 122, there is no risk of the driving power source being damaged, and the entire machine is The lifespan can be maintained.
