One end of this screw member 4 is connected to the stepping motor 1 via the rotational connection member 3, and the other end is supported by the bearing 2. A guide bar 5 is installed parallel to the screw member 4, and a moving member 6 is attached to the guide bar 5.

問題があった。By the way, the screw member 4, which is a conventional intermittent feed component used in the feed mechanism of this woodcutter, is as shown in its unfolded state in FIG. Therefore, by using a thread cutting lathe etc., it can be processed relatively easily and with high precision.
Rotation angle of 00.45°, 90°, 135°, 180'
, 225°, 270°, and 315°, if the movement of the moving member 6 is to be stopped intermittently at 8 points, the position of the moving member 60 may change proportionally due to variations in the rotation angle of the screw member 4 or discrepancies in rotation control. There was a problem with reliability because the system would shift and it would not be possible to stop at the proper position. Furthermore, as mentioned above, feed amount errors tend to occur due to deviations in the rotation control of the stepping motor 1, so in order to reduce this error, it is necessary to use a highly accurate, that is, expensive, stepping motor, or to use a spiral #- It is conceivable to use a special screw part with a 9° advance angle θ, but using an expensive stepping motor would be a cost disadvantage, and it would be difficult to machine a specially shaped spiral groove. This requires an NC lathe, a special thread cutting lathe, etc., and there is also the problem that it becomes an expensive part for intermittent feeding.

ッター１０を連続回転すれば良い。A new V-shaped groove A2 is formed at a position shifted 16 pitches in the axial direction from the groove A2 formed by the groove A2. Further, when the cutter 10 and the workpiece 14 rotate, as shown in FIG. Cutting blade a1
A V-shaped groove A having the same depth is formed. Therefore,
The groove A formed by this cutting edge a is the groove A formed by the cutting edge a2.
, there is a deviation in the axial direction, and the groove A1 due to the cutting edge a1
There is a selling pitch deviation in the axial direction. However, the depth of the groove A2 formed by the small-diameter cutting blade a2 is shallower than the depth of the groove A1°A formed by the large-diameter cutting blades a1 and cutting blades a3. and the cutting edge a3.
The connecting portion of A is chamfered by the groove A formed by the cutting edge a2. Thereafter, by rotating the cutter 10 once, a groove with a relatively long linear bottom formed by a large-diameter cutting blade and a chamfering groove formed by a small-diameter cutting blade are formed on the outer circumference of the workpiece 14. , a total of 16 pieces alternately in the circumferential direction, and
6 cut J-10 blade rows (121 rows of a-t in this example) in a state that is sequentially shifted by a pitch in the axial direction.
It is formed with a threaded portion of the same length. Note that it is difficult to cut a groove of the desired depth with one contact trajectory, so in this case, the feed amount of the cutter 10 is reduced to reduce the cutting amount of each cutting edge 1301 times (and The workpiece 14 and cutter 10 may be rotated continuously.

The groove portions 16 are parallel to the perpendicular line Yic orthogonal to the axis X of the shaft 15, that is, the advance angle 01 is zero, and eight groove portions are formed at equal intervals in the circumferential direction and are shifted by one pitch in the axial direction. Further, eight chamfered portions 17 are provided at equal intervals in the circumferential direction, and are arranged on the shaft 1 .

も使用可能である。The pointed end 8 of the moving member 6 shown in FIG. 1 described above is slidably fitted into the spiral groove 18 of the intermittent feed component having such a structure. In a feeding mechanism equipped with such an intermittent feeding component, when the pointed end portions 8 slide within the chamfered portions 17 as the shaft 15 rotates,
When the movable member 6 moves in a predetermined direction in accordance with the advance angle θ2 of the chamfered portion 17 and the tip portion 8 comes into the groove portion 16,
The power supply to the stepping motor 1 is cut off, and the movement of the moving member 6 is stopped. In this manner, the movable member 6 is fed intermittently by being fed at the chamfered portion 17 and stopped at the groove portion 16, but each movement of the movable member 6 is smoothed by the chamfered portion 17. As mentioned above, groove 1
6, the advance angle θ1 is zero, so even if the rotation angle of the intermittent feeding component deviates somewhat, the stopping position of the # moving member 6 is appropriate. Because of this tx, the accuracy of the stepping motor is not required to be very high, and even inexpensive stepping motors can be used.

Moreover, since the accuracy of the spiral groove is determined by the IR degree of each cutting edge of the cutter, it is possible to provide a spiral groove 149 in the stack. If a member having such a spiral shape is used for the intermittent feeding rock 44, etc., it is possible not only to increase the stopping position of the moving member without using a high-precision, high-turn stepping motor, but also to increase the stopping position of the moving member. can be sent smoothly.
