The inner side of the limiting rod 16 extends into the interior of the slider 8.

[0026] As a technical optimization of this utility model, the limiting mechanism 12 can limit the slider 8 and prevent it from shaking.

[0027] refer to Figure 2 A limiting groove 17 is provided on the outer side of the slider 8, and the inner side of the limiting rod 16 is engaged inside the limiting groove 17.

[0028] As a technical optimization of this utility model, by setting the limiting groove 17, the limiting rod 16 can be more securely engaged inside the slider 8, avoiding the phenomenon of falling off.

[0029] refer to Figure 5 Vertical grooves 18 are provided on both sides of the front of the base 1, and the back of the slider 8 is slidably connected to the inside of the vertical grooves 18.

[0030] As a technical optimization of this utility model, the vertical groove 18 enables the slider 8 to slide more smoothly inside the base 1, reducing the friction between the slider 8 and the base 1.

[0032] As a technical optimization of this utility model, the design of the grip bar 19 makes it easier for users to pull the rear plate 10, thus increasing user convenience.

[0033] refer to Figure 4 The bottom of the rear plate 10 is provided with a groove 20, and the top of the vertical plate 9 is slidably connected to the inside of the groove 20.

[0034] As a technical optimization of this utility model, the groove 20 enables the vertical plate 9 to slide more smoothly inside the rear plate 10, reducing the friction between the vertical plate 9 and the rear plate 10.

[0039] The working principle and usage process of this utility model are as follows: First, the user presses the start button of the motor 4, and the motor 4 starts to run. Its output end drives the transmission disk 5 to rotate. When the transmission disk 5 rotates, the transmission pin 6 fixed on the top front of the transmission disk 5 also makes a circular motion. Since the transmission pin 6 is sleeved in the transmission frame 7, the circular motion of the transmission pin 6 drives the transmission frame 7 to move upward. The upward movement of the transmission frame 7 drives the vertical plates 9 fixed on both sides of its top to move upward. The upward movement of the vertical plates 9 drives the rear plate 10 to move upward, thereby causing the support fixed on the bottom rear side of the rear plate 10 to move upward. The rod 11 moves upward, causing the support rod 11 to move to a suitable height and contact the bottom of the external workpiece, providing stable auxiliary support for the workpiece. This achieves the effect of providing auxiliary support for the workpiece after the clamping is released. Then, when the slider 8 moves to the appropriate position, the moving plate 15 is released. Under the elastic force of the spring 14, the moving plate 15 moves inward, causing the limiting rod 16 to move inward, so that the limiting rod 16 is engaged in the limiting groove 17 on the outside of the slider 8, and the slider 8 is re-limited and fixed, ensuring that the slider 8 is in a stable position and achieving the effect of positioning it.

[0040] In summary, this aerospace parts milling fixture changes the traditional phenomenon where the workpiece falls directly after being released from the clamp. It uses a support rod 11 that moves upward to provide auxiliary support for the external workpiece, increasing the mass of the external workpiece and ensuring the accuracy of subsequent processing.
