A groove 601 is also opened on one side of the base 6 for mounting the adjustable die body 5.
[0033] Figure 3 is a schematic structural diagram of the workpiece 3 to be processed provided by the prior art. As Figure 3 shown in the figure, the workpiece body is cylindrical, and holes need to be drilled on its cylindrical side wall, that is, the processing hole 301. For this reason, a positioning sleeve 4 is provided in this embodiment. As Figure 4 , Figure 5 shown in the figure, there are two mounting sleeves, and the two mounting sleeves are respectively inserted through the mounting holes at the top and the bottom of the base 6. Figure 6 is a schematic structural diagram of the positioning sleeve provided by an embodiment of the present invention. As Figure 6 shown in the figure, each end of the positioning sleeve 4 is provided with a flanging protruding outward for being stuck on the edge of the mounting hole 602, which is convenient for installation and extraction. The size of the mounting sleeve can be adjusted according to the size of the workpiece 3 to be processed, ensuring an interference fit between the outer wall of the positioning sleeve 4 and the mounting hole 602, and the inner diameter of the positioning sleeve 4 being adapted to the outer diameter of the workpiece 3 to be processed.
[0034] Figure 7 is a schematic structural diagram of the adjustable die body provided by an embodiment of the present invention. As Figure 7 shown in the figure, the adjustable die body 5 is generally circular, and is covered with guiding holes 502. The sizes of the guiding holes 502 are different and are made according to the hole processing requirements of different types of workpieces 3 to be processed.

When the adjustable die body 5 is installed in place, the outer surface of the adjustable die body 5 is flush with the side surface of the base 6.
[0035] Figure 8 is a side sectional view of the adjustable multi-hole drilling die device provided by an embodiment of the present invention. As Figure 8As shown, before processing, the adjustable die body 5 is first installed into the groove 601, and the two positioning sleeves 4 are inserted into the mounting holes 602 at the top and bottom of the base 6. At this time, the workpiece 3 to be processed is inserted into the positioning sleeve 4 at the top. According to the position of the hole to be drilled on the workpiece 3 to be processed, the adjustable die body 5 is rotated until the guiding hole 502 of the corresponding size is rotated to the position of the hole to be drilled, and the guiding hole 502 is used for the drilling operation.

In addition, the adjusting screw 1 passes through the fixed pressing plate 2 and is threadedly connected to the fixed pressing plate 2, and the end is in contact with the end of the workpiece 3 to be processed. When the adjusting screw 1 is rotated, the pressing degree on the workpiece 3 to be processed can be adjusted. For workpieces 3 of different models, the pressing degree on the workpiece 3 to be processed can be ensured by adjusting the fixed screw 7 and the adjusting screw 1, so as to prevent the workpiece 3 to be processed from rotating under the action of the drilling force during drilling, thereby affecting the drilling accuracy.

Actually, it can be set according to the actual workpiece model.
[0046] As an alternative embodiment, the positioning sleeve 4 is in interference fit with the mounting hole 602.
