The workpiece in the groove is then rounded by the round grinding wheel, which avoids the positional deviation caused by the manual method and the mechanical arm placing the workpiece, and improves the accuracy of the spheronization. In addition, 200927380, the rounding fixture and the spheronization method can round and round multiple workpieces, which improves the spheronization efficiency. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1, a first embodiment of the present invention provides a rounding jig 100. The rounding jig 100 includes a clamping mechanism 12 and a base 14. The holding mechanism 12 is used to hold the workpieces 30 closely arranged together in a spheronization process. In the embodiment, the workpieces 30 are square. The clamping mechanism 12 includes a first clamping portion 122 and a second clamping portion 124. The first clamping portion 122 includes a first driver 126, a first rotating rod 128, and a first contact member 130. The first driver 126 is coupled to one end of the first rotating rod 128 for driving the first rotating rod 128 to rotate about a central axis of the first rotating rod 128. The end surface of the other end of the first rotating rod 128 is fixed with a first contact member 130 which is in contact with the workpiece 30 when the workpiece 30 is held by the clamping mechanism 12. The second clamping portion 124 includes a second driver 132, a second rotating rod 134 and a second contact member 136. The second driver 132 is coupled to one end of the second rotating rod 134 for driving the second rotating rod 134 to rotate about a central axis of the second rotating rod 134. A second contact member 136 is fixed to the end surface of the other end of the second rotating rod 134. The second contact member 136 is in contact with the workpiece 30 when the workpiece 30 is held by the clamping mechanism 12. The material of the first contact member 130 and the second contact member 136 is an elastic material such as a rubber or an elastic epoxy material. 200927380 The first clamping portion 122 is disposed opposite to the second clamping portion 124, wherein the central axes of the first rotating rod 128 and the second rotating rod 134 are on the same straight line. The first contact member 130 and the second contact member 136 are disposed opposite each other for contacting and holding the workpiece 30. The second clamping portion 124 is movable along the central axis direction of the second rotating rod 134, that is, the second contact member 136 can be moved in the direction of approaching and away from the first contact member 130, so that the clamping mechanism 12 can be clamped differently. Number 30 of workpieces of different thicknesses. It can be understood that the first clamping portion 122 can also be designed to move toward and away from the second clamping portion 124 in the direction of the central axis of the first rotating rod 128, and is not limited to the embodiment. The base 14 has a rectangular parallelepiped shape, and the surface 142 of the base 14 is provided with a V-shaped recess 144 for carrying the workpiece 30. The side walls of the recess 144 are two mutually perpendicular inclined faces 146, and two adjacent sides of the workpiece 30 are placed against the inclined faces 146. In this embodiment, it is preferable that the angle between the two inclined surfaces 146 and the surface 142 of the base 14 is 45 degrees, so that the workpiece 30 is more stable when placed in the groove 144, and the inclination is less likely to occur. It can be understood that the angle between the two inclined faces 146 can also be other angles, which can be determined according to the specific shape of the workpiece 30. The rounding jig 100 further includes two top blocks 16 which are cylindrical and have a radius of radial section equal to the radius of the finished circular workpiece of the workpiece 30 after predetermined rounding. The material of the top block 16 may be a material having a relatively large specific gravity such as iron, copper, or non-recorded steel. When the plurality of workpieces 30 are stacked to form a workpiece group and placed in the recess 144, the two top blocks 16 respectively abut against the two end faces of the workpiece group formed by the plurality of workpieces 30, and the axial direction and the V shape of the top block 16 The grooves 144 extend in the same direction so that the workpiece is closely aligned within the recess 200927380 slot 144. In addition, since the radius of the radial section of the top block 16 is equal to the radius of the finished circular workpiece after the workpiece 30 is rounded, the workpiece 30 can be compared with the top block 16 to determine whether the size of the workpiece 30 is appropriate. That is, whether the workpiece 30 can be rounded into a round finished workpiece that conforms to specifications. Referring to FIG. 2, a second embodiment of the present invention provides a method for rounding a plurality of workpieces 30 by using the rounding jig 100 of FIG. 1, which includes the following steps: (1) placing a plurality of workpieces 30 to be rolled into the base 14 In the recess 144, the crucible is placed and the workpiece 30 is superposed in the recess 144. (2) contacting the first contact member 130 of the first clamping portion 122 and the second contact member 136 of the second clamping portion 124 with the two workpieces 30 located at the outermost side of the plurality of workpieces 30, respectively, and the plurality of workpieces 30 clamping. (3) The base 14 is removed, and the workpiece is rounded by a round grinding wheel 18 (such as the round grinding wheel 18 in Fig. 5) to obtain a round finished workpiece. Referring to FIG. 1 and FIG. 3 to FIG. 5, the specific process of rounding the plurality of workpieces by the rounding jig 100 is as follows: In the step (1), the plurality of workpieces 30 to be rolled into the groove 14 of the base 14 are placed. The top block 16 is placed against the two workpieces 30 located at the outermost side of the plurality of workpieces 30 such that the plurality of workpieces 30 are close to each other and are closely arranged in the recesses 144. In the step (2), the first contact member 130 of the first clamping portion 122 and the second contact member 136 of the second clamping portion 124 are respectively adjacent to the end faces of the two top blocks 16. When the first contact member 130 and the second contact member 136 contact the two top blocks 16, respectively, but the two top blocks 16 are not under pressure, the two top blocks 200927380 16 are removed. Then, the first contact member 130 and the second contact member 136 are respectively brought into contact with the two outermost workpieces 30 of the plurality of workpieces 30 and clamped to the workpiece group. In this embodiment, the central axis of the first rotating rod 128 of the first clamping portion 122, the central axis of the second rotating rod 134 of the second clamping portion 124, and the central axis of the plurality of workpieces 30 are located on the same straight line. It can be understood that the top block 16 can also be removed before the start of the step (2) after the completion of the step (1), and is not limited to the embodiment. In step (3), the base 14 is removed, that is, the plurality of workpieces 30 are separated from the base 12, and at this time, the plurality of workpieces 30 are clamped between the first clamping portion 122 and the second clamping portion 124. The bottom is fixed. A round grinding wheel 18 is provided. The round grinding wheel 18 is connected to a driving device (not shown) for driving the round grinding wheel 18 to rotate. The rotating shaft of the round grinding wheel 18 and the first rotating rod 128 are provided. The center axis is parallel. The driving device is controlled to drive the round grinding wheel 18 to rotate, and at the same time, the first driving unit 126 and the second driving unit 132 are controlled to rotate the first rotating rod 128 and the second rotating rod 134, respectively. When viewed from the end of the first driver 26, the first rotating rod 128, the second rotating rod 134, and the round grinding wheel 18 rotate in the same direction, such as the rotation direction of the first rotating rod 128, the second rotating rod 134, and the round grinding wheel 18. Both are clockwise; the rotational speed of the first rotating rod 128 and the second rotating rod 134 are the same. The round grinding wheel 18 is brought close to the workpiece group, and the workpiece 30 is rounded to obtain a round finished workpiece. Compared with the prior art, the rounding jig 100 adopts a base 14 to closely arrange the plurality of workpieces 30 in the grooves 144 of the base 14, and then the first clamping portion 122 and the second clamping portion 124 are closely clamped. The workpiece 30 is arranged in the recess 11 of the base 14 in the 200927380 slot 144, and then the workpiece 30 is rounded by the round grinding wheel 18, thereby avoiding the positional deviation caused by the manual method and the mechanical arm placing the workpiece 30, thereby improving the accuracy of the rounding. In addition, the rounding jig 100 can round the plurality of workpieces 30 to improve the spheronization efficiency. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
