Description

  The present invention relates to a processing device and a processing method for performing processing such as grinding.

  A rolling bearing having an inner ring and an outer ring and a plurality of rolling elements arranged between them is known. A track on which the rolling elements roll is formed on the outer peripheral surface of the inner ring and the inner peripheral surface of the outer ring, and this track is ground by a grinder in the process of manufacturing the rolling bearing (for example, refer to Patent Document 1). The grinding machine rotates an annular work such as an outer ring while holding it by a holding device such as a magnet catch, and further moves the grinding wheel to the grinding position to grind the surface to be ground (orbit) of the work. Is configured.

  By the way, when the rolling bearing is a tapered roller bearing, the inner race and the outer race are formed with tapered raceways inclined with respect to the axis. Also, when the type of tapered roller bearing (such as the product model number) changes, the angle of the raceway with respect to the shaft center may change. In a conventional grinding machine, a holding device for holding a work is configured to be capable of changing its posture in order to cope with a change in an angle of a track which is a surface to be ground.

  For example, FIG. 9 shows a grinder 110 including a holding device 131 capable of changing its posture according to the angle of the surface to be ground of the work W. The holding device 131 is rotatably provided around a vertical axis C, and has a small angle (see FIG. 9A) with respect to the axis O of the workpiece W and a large angle (see FIG. 9A). 9 (b)), the posture is changed. Further, the grinding machine 110 is provided with a work input part 136 for inputting the work W and a work discharge part 137 for discharging the work W after grinding, and follows the posture of the holding device 131. The work input part 136 and the work discharge part 137 are also configured to move.

As shown in FIG. 9, the grinder 110 receives the work W discharged from the grinder 110 and the loading side transfer device 191 that carries the work W from the previous process and loads the work W into the grinder 110. A discharge side transfer device 192 for transferring the work W is connected.
However, in the conventional grinder 110, when the posture of the holding device 131 changes according to the angle of the surface to be ground of the work W, the positions of the work input unit 136 and the work discharge unit 137 also change, and the work W transport path is changed. Changes are needed. In addition, the transfer path may also need to be changed due to changes in other dimensions of the work W (inner diameter, outer diameter, etc.). Therefore, before and after the attitude of the holding device 131 is changed, the loading side transport device 191 and the discharge side transport device 192 cannot be used in the same manner, and the transport devices 191 and 192 may be moved according to the type of the work W, It was necessary to change the equipment such as replacing the transport devices 191, 192 with different ones. The transfer devices 191 and 192 themselves do not perform substantial processing or the like, but simply transfer the work between the grinding device and the pre-process device or the post-process device, so that the process is as simple and inexpensive as possible. It is required to configure. Therefore, it is not preferable to change the equipment related to the transfer device according to the type of work. Further, in a work manufacturing facility, since the grinder 110 usually constitutes a part of the manufacturing line, the grinding machine 110 is simply transferred due to a relationship with another device on the same manufacturing line (for example, installation space limitation). There is a case where it is not possible to deal with the change of the kind of the work only by moving or exchanging the devices 191, 192, and it is necessary to change the whole manufacturing line.
