本発明は、数値制御（ＮＣ）シェービング盤におけるカ
ッタと被削歯車との自動位置決めに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field] The present invention relates to the automatic positioning of a cutter and a workpiece gear in a numerically controlled (NC) shaving machine.
従来のＮＣシェービング盤ではカッタと被削歯車との関

してみて不具合があるとデータを微調整し、再び計測す
るという作業を繰り返していた。With conventional NC shaving machines, the relationship between the cutter and the workpiece gear, especially the axis position or axis intersection angle, is determined by manually moving the machine in advance and inputting the coordinate data, and then measuring it and fine-tuning the data if there is a problem. The process of adjusting and measuring again was repeated.
ここで、その位置決め方法を説明すると、中心距離の位

なので省略する。Here, the positioning method will be explained. In the procedure for positioning the center distance and setting the axis intersection angle, first align the width center of the gear to be cut with the turning center of the cutter. This task is easy and will be omitted.
次に、被削歯車に赤ペンキ等を塗り、手動で被削歯車と

カッタ全回転石せる。Next, paint the gear to be cut with red paint, etc., and manually bring the gear to be cut and the cutter closer together. The point where the workpiece gear and cutter mesh and there is no backlash is set as a temporary center distance, and the cutter rotates fully at this point.
この時の赤ペンキの当シ具合をみなから軸交差角と中心
距離とを微調整する。At this time, finely adjust the axis intersection angle and center distance depending on how well the red paint is applied.
当りが一様になったら、切込みｔ与えて加工する。加工
後、被削歯車のオーバピンを測定し。When the contact is uniform, give a depth of cut t and process. After machining, measure the overpin of the gear to be cut.

削歯車を２０００〜５０００個加工すると刃付けをする
。刃付後は再度上記の精度出し作業が必要である。If the overpin is within the accuracy standard tolerance, measure the tooth trace and tooth profile using a precision measuring instrument. Generally, several trial cuttings are required before the accuracy is acceptable through precision measurement, which is a time-consuming process. Also, the shaving cutter is fitted with a blade after 2,000 to 5,000 gears have been processed. After setting the blade, it is necessary to perform the above-mentioned accuracy work again.

それ等もあつ几。For those who have to manually move the machine for each product, enter the coordinates as data, measure it, and if a problem is found, fine-tune the data and measure again. It was a few hours ago. Also, this work was required every time the cutter blade was reattached. Furthermore, did you make a mistake in transferring the data? There is also a risk that this may occur.
本発明は、このような従来の不具合に鑑み。The present invention was developed in view of such conventional problems.
