By the way, in a conventional processing machine, when a workpiece is machined using a machining center, a hole is formed in the workpiece, and then the edge of the hole drilled in the workpiece is formed. When performing the chamfering, the chamfering can be performed at the same position by changing the processing tool, and a series of processing can be automated. However, in order to automate a series of processing using a machining center, the machining center itself becomes large and large, and the equipment cost becomes expensive. For example, in the case of a long work such as a track rail, when a large number of holes such as mounting holes are formed at a certain pitch, the hole pitch may be machined to the same pitch because the work is long. At present, it is difficult, holes are formed within an allowable range, and the hole pitch varies at present. Therefore, the pitch between the holes drilled in the workpiece varies, so in simple and simple processing such as chamfering holes such as mounting holes, the chamfering of the hole edges using a machining center is not performed. Currently, it is processed manually.

In order to automate the chamfering of a hole in a workpiece without using a large-scale processing machine such as a machining center, a processing machine corresponding to a positional shift of a hole such as a mounting hole formed in the workpiece. Need to be adjusted. If the chamfering of the hole is performed without adjusting the processing machine in accordance with the misalignment of the hole, the position of the hole and the chamfer will be misaligned, and the chamfered surface will be distorted, resulting in a poor finish. Would. Therefore, at present, it is desired to develop a position shift adjusting / transmitting device such as a processing jig device that eliminates or absorbs the position shift and automates the boring or chamfering process in the processing machine.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to form a hole or chamfer in a workpiece by transmitting a driving force from a first rotating body such as a chuck in a processing machine to a second rotating body such as a working tool. Even if the positions of the rotation centers of the first rotating body and the second rotating body are slightly displaced, the rotation axis is corrected by a pair of linear motion rolling guide units in accordance with the displacement.

In the adjustment transmitting device, the track rail 71 and the track rail 74 move relative to each other, and the slider 72 and the slider 73 do not move relative to each other.

The position shift adjusting transmission device shown in FIG. 15 applies the principle of the torque transmission type coupling shown in FIG. 17 to a processing tool device incorporated between a chuck of a processing machine and a rotary tool.

As described above, the misalignment adjusting transmission device according to the present invention is formed at intervals along the longitudinal direction of a long workpiece such as a track rail. When applied to machining where the edge of a hole such as a mounting hole is chamfered, even if the rotation axis of the chuck of the processing machine and the rotation axis of the processing tool are eccentric, the amount of eccentricity is determined by a pair of independent axes. It can be adjusted and absorbed through a linear motion rolling guide unit which moves relatively to the workpiece, and can perform chamfering with high accuracy on the edge of a hole formed in the workpiece. In addition, the torque transmitted from the chuck to the processing tool is smoothly transmitted without changing the rotation angular velocity of the chuck in the processing machine, so that there is no distortion in the chamfering and no misalignment between the hole and the hole chamfer. Therefore, automation of the processing machine can be simplified, and efficient processing can be achieved.
