Description

Rounding device

The present invention relates to the field of workpiece spheronization, and more particularly to a spheronization apparatus for centering and spheronizing a workpiece.

The spheronization device is widely used to grind workpieces of various shapes into a circular shape (see "High Efficiency Deep Grinding of a Low Alloy Steel with Plated CBN Wheels", CIRP Annals-Manufacturing Technology, pp. 241-244, Volume 51, Issue 1, 2002). 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 central axis of the workpiece to be rolled 12 is generally required to be on the same line as the central axis of the drive shaft 120 to ensure the centering and spheronization accuracy of the workpiece 12 to be rolled. The driving 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 to achieve rounding of the workpiece 12 to be rolled.

During the spheronization process, the workpiece 12 to be ground is usually placed between the first clamping member 100 and the second clamping member 110 for clamping, which is easy to cause the position of the workpiece 12 to be ground. The deviation causes a deviation between the central axis of the workpiece 12 to be rolled and the central axis of the transmission shaft 120, 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 120, the deviation should be corrected to ensure the accuracy of the rounding of the workpiece 12 to be rolled.

However, it is difficult for the spheronization apparatus 10 to correct the deviation between the central axis of the workpiece 12 to be circled and the central axis of the transmission shaft 120. Therefore, the workpiece 12 to be spheronized needs to be detached and reinstalled, and the workpiece to be circulated again is detected. Whether the central axis of 12 coincides with the central axis of the drive shaft 120 is repeated until the central axis of the workpiece to be rolled 12 coincides with the central axis of the drive shaft 120. The spheronization apparatus 10 is time consuming and labor intensive, and the production efficiency is low.

In view of the above, it is necessary to provide a spheronization apparatus 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 production efficiency.
