[0020] The following will further describe the specific implementation manners of the present utility model in conjunction with the appended Figure 1-7 drawings.

[0021] The moving scroll keyway milling device includes a bottom plate 1. The bottom plate 1 is a rectangular plate - type structure. At the center of the top of the bottom plate 1, a base 2 is installed through a first positioning pin 14 and fastened by a first hexagon socket head bolt 3. The base 2 is a hollow cylindrical structure. On both opposite sides of the base 2, cut surfaces are provided. At one of the cut surfaces, a positioning block 6 is arranged. The positioning block 6 is installed on the bottom plate 1 through a second positioning pin 7 and fastened by a third hexagon socket head bolt 8. On the surface of the other cut surface, a stainless steel bead screw 13 is installed. At the top of this cut surface, a limit block 11 is installed. The limit block 11 is installed in the groove 15 of the base 2 and fastened by a bolt passing through the bolt hole 12. The stainless steel bead screw 13 is installed in the threaded hole 16 of the base 2. On the other two opposite sides of the base 2, a first corner cylinder 4 and a second corner cylinder 9 are arranged. The first corner cylinder 4 is installed on the bottom plate 1 through a second hexagon socket head bolt 5, and the second corner cylinder 9 is installed on the bottom plate 1 through a fourth hexagon socket head bolt 10.

[0022] During operation, the workpiece is installed on the base 2. The stainless steel bead screw 13 presses the workpiece against the side surface 17 of the positioning block 6. The tail of the workpiece's scroll line leans against the limit block 11, and the first corner cylinder 4 and the second corner cylinder 9 are used to press the workpiece.
