Conventionally, in machine tools that process workpieces sequentially using multiple spindles, workpiece conveyance involves transferring the workpiece between the chucks of each spindle or transferring the workpiece to or from the spindle chuck. A device is provided that includes a rotating plate having a plurality of arms and a gripping device detachably fixed to the tip of the arm with bolts. By the way, when machining a workpiece that has an eccentric part and a concentric part in sequence using multiple spindle chucks, the conveyance device moves the spindle chuck that processes the eccentric part to a position that is offset from the center of rotation of the spindle by a dimension corresponding to the amount of eccentricity. It is necessary to transfer the workpiece at a position concentric with the rotation center of the main spindle for machining a concentric part. Therefore, each time the transfer device receives a workpiece from one of the spindle chucks and transfers it to the other, the dimension from the center of rotation of the rotating plate to the gripping position of the gripping device must be changed. However, in the above-mentioned conventional technology, the gripping device is fixed to the rotary plate with bolts, so the machine must be stopped during processing and the bolts must be loosened to relocate the gripping device, or the gripping device must be removed. It was necessary to take measures such as replacing it. Therefore, the conventional conveyance device is not suitable for practical use when machining a workpiece having an eccentric portion and a concentric portion.
