[0018] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0019] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, an improved large rotating shaft fixture includes two groups of fixture main bodies 1. A large rotating shaft workpiece 4 is placed on the two groups of fixture main bodies 1. Two mounting brackets 2 are symmetrically and fixedly installed on the fixture main body 1. A limiting component 3 is movably installed on the fixture main body 1 and the two mounting brackets 2. The limiting component 3 is composed of a bidirectional lead screw 11, an internal hexagonal rotating block 12 and a limiting block 13. There are two internal hexagonal rotating blocks 12 and they are symmetrically and fixedly installed at both ends of the bidirectional lead screw 11. There are two limiting blocks 13 and they are symmetrically installed on the bidirectional lead screw 11. When processing the large rotating shaft workpiece 4, the large rotating shaft workpiece 4 can be placed on the two groups of fixture main bodies 1, and the large rotating shaft workpiece 4 is located between four limiting support plates 6. Then, the limiting component 3 is used to further limit the large rotating shaft workpiece 4. The method is to simply rotate the bidirectional lead screw 11 on the mounting bracket 2, so that the limiting block 13 is sleeved on the large rotating shaft workpiece 4 through the limiting slot 15; when the large rotating shaft workpiece 4 needs to be flipped, the large rotating shaft workpiece 4 can be lifted upward, and then the large rotating shaft workpiece 4 is flipped around its axis. Then, the flipped large rotating shaft workpiece 4 is placed on the fixture main body 1, and at the same time, the large rotating shaft workpiece 4 is stuck in the limiting slot 15.

[0020] Finally, by setting the fixture main body 1, the mounting bracket 2 and the limiting component 3, it is convenient to flip and process the large rotating shaft workpiece 4, and at the same time, it can provide a stable support and fixing effect for the large rotating shaft workpiece 4, so as to ensure better machining accuracy of the large rotating shaft workpiece 4. At the same time, the large rotating shaft workpiece 4 can have a higher machining efficiency, and the qualified rate of machining the large rotating shaft workpiece 4 can be improved.

[0021] Further, the fixture main body 1 is composed of a mounting base plate 5, limiting support plates 6 and a connecting fixing plate 7. There are two limiting support plates 6 and they are symmetrically and fixedly installed at the upper end of the mounting base plate 5. The connecting fixing plate 7 is fixedly installed at the upper end of the mounting base plate 5, and the connecting fixing plate 7 is also fixedly installed at the inner ends of the two limiting support plates 6. The large rotating shaft workpiece 4 is placed between the two limiting support plates 6 on the fixture main body 1. The limiting support plates 6 on the fixture main body 1 can provide support for the large rotating shaft workpiece 4 and can also limit the large rotating shaft workpiece 4.

[0022] Further, the mounting bracket 2 is located outside the limit support plate 6. The mounting bracket 2 is composed of a fixed bottom plate 8 and a support block 9. The support block 9 is fixedly installed at the upper end of the fixed bottom plate 8, and the fixed bottom plate 8 is fixedly installed at the upper end of the mounting bottom plate 5. An installation through hole 10 is formed in the support block 9 on the mounting bracket 2, and the installation through hole 10 penetrates through the support block 9. The bidirectional lead screw 11 on the limit assembly 3 is rotatably installed in the two installation through holes 10 formed in the two support blocks 9. The hexagon socket rotating block 12 is located outside the support block 9. An installation slot 14 is formed at the lower end of the limit clamping block 13. The limit clamping block 13 is slidably sleeved on the connecting fixed plate 7 through the installation slot 14. An installation screw hole 16 is formed in the limit clamping block 13, and the limit clamping block 13 is installed on the bidirectional lead screw 11 through the installation screw hole 16. A limit slot 15 is formed at the upper end of the limit clamping block 13, and the limit clamping block 13 is clamped on the large rotating shaft workpiece 4 through the limit slot 15. When using the limit assembly 3 to further limit the large rotating shaft workpiece 4, a tool can be inserted into the hexagon socket rotating block 12, and then the bidirectional lead screw 11 is rotated through the hexagon socket rotating block 12. At this time, the bidirectional lead screw 11 will rotate in the installation through hole 10 on the mounting bracket 2. At this time, since the limit clamping block 13 is sleeved on the connecting fixed plate 7 and the limit clamping block 13 is threadedly connected to the bidirectional lead screw 11, the limit clamping block 13 will not rotate together with the bidirectional lead screw 11, and the limit clamping block 13 will move with the rotation of the bidirectional lead screw 11. Finally, when the limit clamping block 13 is sleeved on the large rotating shaft workpiece 4 through the limit slot 15, the further limitation of the large rotating shaft workpiece 4 by using the limit assembly 3 is completed.
