As shown in FIG. 1, a typical spheronization device 10 includes a first clamping member 100, a second clamping member 110, and two of which are respectively threadedly coupled to the first clamping member 100 and the second clamping member 110. The drive shaft 120 and a grinding wheel 130. The central axes of the first clamping element 100, the second clamping element 110 and the transmission shaft 120 are on the same straight line. The central axis of the drive shaft 120 is aligned with the central axis of the grinding wheel 130 in the Y direction as shown in FIG. The first clamping element 100 cooperates with the second clamping element 110® to clamp and secure the workpiece 12 to be rounded. The center axis of the workpiece to be rolled 12 is generally required to be in line with the central axis of the drive shaft 120 to ensure the centering and spheronization accuracy of the workpiece 12 to be rolled. The drive shaft 120 is configured to drive the first clamping member 100 and the second clamping member 110 to rotate to drive the workpiece 12 to be rotated, thereby assisting the grinding wheel 130 in achieving rounding of the workpiece 12 to be rolled. During the spheronization process, the workpiece 12 to be ground is usually manually placed between the first clamping member 100 and the second clamping member 110 to be clamped at 200936315, which easily causes the position of the workpiece 12 to be ground. A deviation is generated such that a deviation occurs between the central axis of the workpiece 12 to be rolled and the central axis of the drive shaft 12', thereby reducing the accuracy of the rounding of the workpiece 12 to be rolled. Therefore, when a deviation occurs between the central axis of the workpiece 12 to be rolled and the central axis of the drive shaft 12, the deviation should be corrected to ensure the rounding accuracy of the workpiece 12 to be rolled. However, it is difficult for the spheronizing device to correct the deviation between the central axis of the workpiece 12 to be circled and the central axis of the transmission shaft 12, and therefore, it is necessary to disassemble the workpiece 12 to be re-installed and re-detected. Whether the central axis of the workpiece to be rolled 12 coincides with the central axis of the drive shaft 12 is repeated until the center axis of the workpiece 12 to be rolled coincides with the central axis of the drive shaft 120. The spheronization apparatus 1 is time consuming and labor inefficiently produced. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a device capable of correcting the deviation between the center axis of the workpiece to be rolled and the center axis of the drive shaft, thereby improving the production efficiency. & scoop: a type of spheronization device for spheronizing a workpiece, the spheron is mounted with a first drive shaft, - a second one of the first drive shaft opposite the first drive shaft and - and the first drive shaft and The second drive shaft is connected to the device: wherein the clamping fixture comprises: a base, the base is provided with at least one threaded hole; at least a bolt, the bolt is threaded through the threaded hole of the base.
