[Problems to be solved by the device]

 This had the following drawbacks. (A) Since the outer diameter of the part to be rolled of the mating processed material varies, it is disadvantageous and difficult to design and manufacture the rolling tool in accordance with them, in terms of cost and delivery. there were. (B) Therefore, a rolling tool with a certain specification is used for mating processed materials of various outer diameters, and in many cases it is not possible to obtain a glossy and clean finished surface peculiar to rolling processing. It was The present invention has been made to solve these drawbacks.

[0004]

[Means for Solving the Problems]

 In order to obtain a clean rolling surface, it is necessary to divide the outer circumference of the hand-worked material into integers at the tip pitch in the direction perpendicular to the axis of the rolling tool. By dividing this by an integer value, the groove initially carved on the tip of the rolling tool and the tool tooth tip will match after one rotation, and will follow the groove carved first. This is because the rolling process proceeds. If it is not divided by an integer value, the groove initially carved in the tip of the rolling tool and the tool tip will not match after one revolution, and uniform rolling cannot be performed. ， It will not be possible to obtain a clean rolled surface. Therefore, in order to obtain a clean rolling surface, it is indispensable to design the outer circumference of the mating work material by an integer value at the tooth tip pitch perpendicular to the axis of the rolling tool. In particular, in the case of a type in which the teeth of the rolling tool have a helix angle, as shown in Fig. 5, assuming that the helix angle is K0 and the pitch of the teeth of the rolling tool is PN, the tip pitch in the direction perpendicular to the axis is shown. P can be represented by PN / cos (K0). The inventor noticed that the tooth pitch P in the direction perpendicular to the axis is a function of the helix angle K0, and that the tooth pitch P perpendicular to the axis changes by changing the helix angle K0 of the rolling tool. .. However, changing the twist angle K0 itself of the rolling tool means that rolling tools having different twist angles are manufactured and then replaced, and the rolling of the same specifications, which is the object of the present invention, is performed. This is against the situation of dealing with building tools. Here, the inventor has found that by changing the mounting angle of the rolling tool itself to the support portion, the pitch dimension at right angles to the axis can be changed even in the rolling tool having a constant helix angle. It was That is, as shown in FIG. 6, by rotating the mounting angle of the rolling tool by the angle K1 in the direction shown in the figure, the relative twist angle K between the mating workpiece and the rolling tool tooth tip becomes ( K0 + K1), and if it is rotated by an angle K1 in the direction opposite to that in FIG. 6, the relative twist angle K becomes (K0-K1). In this way, the relative twist angle K can be freely changed by changing the mounting angle of the rolling tool. When the relative helix angle is K, the tooth tip of the rolling tool is to divide the outer circumference of the mating work material by the axial tip tooth pitch, PN / cos (K). As described above, according to the present invention, by changing the mounting angle of the rolling tool, the tooth pitch at right angles to the axis that divides the outer circumference of the mating workpiece can be adjusted, and even in mating workpieces of various outer diameters, It is possible to divide the outer circumference by the integer value of the tip pitch dimension at right angles to the axis, and with a rolling tool of a fixed specification, it is possible to perform beautiful rolling even on mating workpieces of various outer diameters. It's about trying to be able to get a face.

Therefore, as shown in FIG. 1, a rolling tool (1) is rotatably engaged with a holding member (3) by a pin (2), and the holding member (3) is supported by a supporting member. (4) Engage rotatably. Further, the mounting angle of the holding member (3) with respect to the support member (4) is finely adjusted by an angle adjusting mechanism (5) having a speed reducing function by a combination of a worm gear (51) and a gear (52) meshing therewith. And

As shown in FIGS. 2 and 3, the angle adjusting mechanism engages the rolling tool (1) by rotating a rotary knob (53) arranged on the support member (4). The holding member (3) that is held is configured so that it can be rotated by an arbitrary minute angle. When the holding part material (3) has a zero mounting angle, that is, when rolling is performed in the conventional state, the outer circumference of the mating material (6) is aligned with the tooth pitch at right angles to the axis of the rolling tool (1). When it is not divisible by the numerical value, the rotary knob (53) is rotated, the holding member (3) is rotated, and the mounting angle of the rolling tool (1) is changed by a small amount, so It is possible to change the tip pitch dimension perpendicular to the axis that engraves the outer circumference of (6), and when rotating an appropriate amount of angle, the outer circumference of the mating workpiece (6) is divided by an integer value and carved. You will be able to. As described above, according to the rolling device of the present invention, even if the outer diameter of the mating work material (6) is various, the rolling tool (1) having a constant specification is used to perform a clean rolling. It is possible to obtain a surface / finished surface.

[Effect of the device]

 According to the rolling apparatus of the present invention, even for mating workpieces having various outer diameters, the rolling angle of the rolling tool is finely adjusted by the adjusting knob, so that the rolling tool of a certain specification is used. However, the outer circumference of the mating processed material can be divided by an integer value by the tooth tip pitch dimension perpendicular to the axis, and a clean rolled surface with a finished surface can be obtained.
