のみで研削部材２がワークＷに押し付けられる。Next, the operation of the automatic chamfering device of the present invention will be described. The grinding tool 3C that swings substantially horizontally will be described on behalf of each of the grinding tools 3A to 3C. The work W has a non-circular inner and outer shape, and the horizontal position and the height of the holder 4 are adjusted so that the grinding member 2 comes into contact with a chamfered portion of the work W at an appropriate angle. And First, in a state before grinding, the rod 7a of the grinding tool control device 7 is in a stretched state and the grinding tool 3C is forcibly rotated, and the grinding member 2 is at a position separated from the workpiece W. Then, when a start command is input from an operation panel (not shown) of the automatic chamfering device, the rod 7a of the grinding tool control device 7 contracts slowly. As described above, since the grinding tool 3C is urged toward the work W by the spring 5, the grinding tool 3C approaches the work W following the movement of the rod 7a, and finally the rod 7a separates and is attached by the spring 5. The grinding member 2 is pressed against the work W only by the force.

部９にあるワークＷを交換する。On the other hand, at a stage before the grinding member 2 comes into contact with the work W, the grinding tool 3C and the work holding means 1 are operated, and the grinding member 2 rotates at a high speed and the work W rotates at a low speed. Accordingly, chamfering is performed at the same time when the grinding member 2 comes into contact with the workpiece W. If the work W is set to be rotated before the chamfering by the grinding tool 3C is started as in this embodiment, only a part of the work W is not deeply excavated. As described above, the inner shape of the work W is non-circular, but since the grinding tool 3C is swingable and urged toward the work W by the spring 5, the grinding tool 3C follows the shape of the work W. 3C swings automatically. Next, when the work W makes one full rotation, the motor of the grinding tool 3C and the work holding means 1 is stopped, and then the rod 7a of the grinding tool control device 7 is extended. As a result, the grinding tool 3C is forcibly rotated in a direction away from the workpiece W, and returns to the initial state and stops. Thus, the chamfering operation is completed, and the work W in the work mounting section 9 is replaced.

転させればよい。When it is desired to increase the amount of chamfering or to increase the swinging speed of the grinding tool 3C due to the large undulation of the workpiece W, the cap body 18 is first fixed by hand to adjust the spring force. Loosen the member 6 and pull out the protrusion 6 a at the tip from the engaging portion 21 of the cap body 18. Then, the cap body 18 is rotated in a direction in which the spring 5 is wound, and the spring force adjusting member 6 is tightened at an appropriate position to fit the projection 6a into the engaging portion 21 of the cap body 18 to lock the cap body 18 in a fixed manner. . As a result, the force of the spring 5 is increased, so that the grinding member 2 is more strongly pressed against the workpiece W and the amount of chamfer increases, or
The swing speed of the grinding tool 3C is improved. When the spring force is reduced, the cap body 18 may be rotated in the opposite direction in the same manner.

が防止できる。The operation of the grinding tool 3C has been described above, but the operation is the same for the other grinding tools 3A and 3B. However, since the grinding tools 3A and 3B can press the grinding member 2 against the workpiece W by their own weight, the role of the spring 5 is exclusively to assist the swing of the grinding tools 3A and 3B. Actually, when the grinding tools 3A and 3B are used only by their own weight, a phenomenon occurs in which the grinding member 2 bounces and dances when the work W has a large step and the grinding tools 3A and 3B swing rapidly. . Even in such a case, the grinding tool 3A,
If the 3B is urged by the spring 5, the dancing phenomenon of the grinding member 2 can be prevented.

た効果がある。The automatic chamfering device of the present invention has a non-circular shape by adopting a configuration in which the grinding tool is made swingable and the grinding tool is urged toward the workpiece by the bias of a spring. Work piece chamfering can be completely automated.
In particular, since the grinding tool is urged by a spring, the orientation of the grinding tool can be freely set unlike the type of pressing against the work by its own weight, so three or more grinding tools are installed around the work. And three or more places can be chamfered at one time. In addition, the spring force acting on the grinding tool can be increased or decreased by the combination of the spring, the cap body, and the spring force adjusting member, so that the chamfer amount can be adjusted as necessary, or from a workpiece having a large undulation and complicated shape. A wide range of simple shapes can be handled accurately. In addition, since the spring is accommodated in the cap body, the chips do not adhere to the spring, and therefore, the troublesome and troublesome work of removing the chips attached to the spring is released, and the efficiency of daily care and cleaning is remarkably improved. improves. In addition, since the spring is not exposed, there is no danger that the work clothing will come into contact with the spring and become dirty or torn.
