In use, the semi-finished workpiece 4 that has been roughly processed is first fixed on the connecting plate 2, the first filler 3 is inserted into the insert hole 5 and the top end of the first filler 3 is ensured to extend out of the top end of the insert hole 5, and then the semi-finished workpiece 4 is further processed. Since the insert hole 5 is blocked by the first filler 3 and the outer peripheral wall of the first filler 3 tightly adheres to the inner peripheral wall of the insert hole 5, the workpiece 4 and the first filler 3 form a tightly combined assembly during the fine processing, and the first filler 3 and the workpiece 4 are milled together during the fine processing. Since the first filler 3 tightly adheres to the insert hole 5 to provide support for the insert hole 5, the outer edge of the top end of the insert hole 5 is not easy to deform during the milling process. In addition, since the first filler 3 blocks the outer edge of the top end of the insert hole 5, the outer edge of the top end of the insert hole 5 is not easy to form burrs during the milling process. Even if small burrs are formed, the burrs will not extend into the insert hole 5 due to the blocking of the first filler 3, and the burrs can be removed more conveniently during the subsequent deburring process. In addition, the first filler 3 also blocks the cutting chips from entering the insert hole 5, thereby protecting the insert hole during the processing compared with the existing jig. The top end of the limiting block 7 abuts against the upper wall of the gap, and the bottom end of the limiting block 7 abuts against the bottom surface of the bottom plate 1, so as to fix the first filler 3 and prevent the first filler 3 from shaking up and down.

The second filler 8 plays a role in protecting the opening 9 during processing in the embodiment, and its principle is the same as that of the first filler 3. The second filler 8 tightly fits the opening 9 to provide support for the opening 9, so that the outer edge of the top end of the opening 9 is not easy to deform during milling. In the embodiment, the first filler 3 and the second filler 8 are consumables, and new first filler 3 and second filler 8 need to be replaced each time.

[0025] Optionally, the embodiment further comprises a gasket 10, the gasket 10 is sleeved on the first bolt, and the gasket 10 is located between the workpiece 4 and the connecting plate 2. By replacing gaskets 10 of different thicknesses, the distance between the workpiece 4 and the connecting plate 2 can be adjusted.
