Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3As shown, this utility model provides an auxiliary device for machining precision aluminum alloy parts, including a machining table 1. Two positioning plates 4 are provided on the upper surface of the machining table 1. A positioning baffle 6 is fixedly provided on the upper surface of one positioning plate 4, and an adjusting mechanism 2 is fixedly provided on the upper surface of the other positioning plate 4. A fixing mechanism 3 is provided inside the adjusting mechanism 2. The adjusting mechanism 2 includes an adjusting frame 20, the lower surface of which is fixedly connected to the upper surface of the positioning plate 4. A lifting screw 21 is rotatably provided on one side of the adjusting frame 20, and a lifting frame 27 is slidably provided inside the adjusting frame 20. Lifting rods 26 are fixedly provided on both sides of the lifting frame 27. A lifting screw groove 28 is provided at one end of one lifting rod 26 away from the lifting frame 27, and the lifting screw groove 28 is threadedly connected to the lifting screw 21. A fastening device is fixed at the other end of the lifting rod 26 away from the lifting frame 27. The screw 25 has a fastening nut 24 threaded on its outer side. When using the adjustment mechanism 2, the lifting screw 21 is first rotated. Since the lifting screw 21 is threadedly connected to the lifting screw groove 28, the rotation of the lifting screw 21 will drive the connected lifting rod 26 and lifting frame 27 to slide up and down within the adjustment frame 20. The sliding of the lifting frame 27 drives the fixing mechanism 3 to move synchronously, thereby achieving precise height adjustment. After adjusting to the appropriate height, the other lifting rod 26 is tightened with the fastening nut 24, which fixes the fastening nut 24 relative to the adjustment frame 20, ensuring the stability of the lifting frame 27 after adjustment. During the adjustment process, the design of the adjustment groove 22 and the lifting groove 23 ensures that the lifting rod 26 and the lifting frame 27 can slide smoothly within the adjustment frame 20, improving the smoothness and accuracy of the adjustment.

[0018] The upper surface of the processing table 1 is provided with multiple positioning holes 7 distributed at equal intervals. Positioning openings 5 ​​are provided on both sides of the positioning plate 4. Adjustment grooves 22 are provided on both sides of the adjustment frame 20. The inner side of the adjustment groove 22 slides against the outer side of the lifting rod 26. Lifting grooves 23 are provided on both sides of the lifting frame 27. The lifting grooves 23 slide against the inner side of the adjustment frame 20. The positioning holes 7 and positioning openings 5, together with bolts, can adjust and fix the position of the positioning plate 4 on the processing table 1. The design of the adjustment grooves 22 and lifting grooves 23 ensures that the lifting rod 26 and the lifting frame 27 can slide smoothly in the adjustment frame 20, improving the smoothness and accuracy of the adjustment.

[0019] The fixing mechanism 3 includes a fixing frame 30, which is fixedly connected to the inner side of the lifting frame 27. A fixing rod 39 is slidably provided on the inner side of the fixing frame 30. A fixing head 37 is fixedly provided at one end of the fixing rod 39, and a moving plate 31 is fixedly provided at the end of the fixing rod 39 away from the fixing head 37. A moving screw 35 is rotatably provided on one side of the moving plate 31. The moving screw 35 is threadedly connected to the inner side of the fixing frame 30. In the fixing mechanism 3, the moving screw 35 is first rotated by rotating the knob 33. Since the moving screw 35 is threadedly connected to the inner side of the fixing frame 30, the rotation of the moving screw 35 will drive the moving plate 31. The fixed rod 39 on the moving plate 31 slides within the fixed frame 30. The sliding of the fixed rod 39 drives the fixed top head 37 to move closer to the workpiece, cooperating with the positioning baffle 6 until the workpiece is tightly clamped. During the clamping process, the positioning accuracy of the workpiece can be ensured by observation or measurement. When it is necessary to release the workpiece, simply rotate the knob 33 in the opposite direction, and the moving plate 31 and the fixed rod 39 on it will slide in the opposite direction under the drive of the moving screw 35, thereby releasing the workpiece. In addition, the design of the clamping groove 36 and the clamping handle 38 can further increase the stability of the moving screw 35 after clamping, avoid loosening, and ensure the stability during the processing.

[0020] A movable groove 34 is provided on one side of the movable plate 31. The movable groove 34 is rotatably connected to the movable screw 35. A knob 33 is fixedly provided at one end of the movable screw 35. Multiple anti-slip grooves 32 distributed in a ring are provided on the outer side of the knob 33. A clamping groove 36 is provided on the lower surface of the fixed frame 30. A clamping handle 38 is inserted into one side of the fixed frame 30. The movable screw 35 can be rotated more conveniently and stably through the knob 33 and the anti-slip groove 32. The design of the clamping groove 36 and the clamping handle 38 can further increase the stability of the movable screw 35 after clamping, avoid loosening, and ensure stability during the processing.

[0021] Working principle: When using the adjustment mechanism 2, firstly, by rotating the lifting screw 21, since the lifting screw 21 is threadedly connected to the lifting screw groove 28, the rotation of the lifting screw 21 will drive the connected lifting rod 26 and lifting frame 27 to slide up and down in the adjustment frame 20. The sliding of the lifting frame 27 drives the fixing mechanism 3 to move synchronously, thereby achieving precise height adjustment. When the appropriate height is reached, the other lifting rod 26 is tightened by tightening the fastening nut 24, which can fix the fastening nut 24 relative to the adjustment frame 20, ensuring the stability of the lifting frame 27 after adjustment. During the adjustment process, the design of the adjustment groove 22 and the lifting groove 23 ensures that the lifting rod 26 and the lifting frame 27 can slide smoothly in the adjustment frame 20, improving the smoothness and accuracy of the adjustment.

[0022] In the fixing mechanism 3, the movable screw 35 is first rotated by rotating the knob 33. Since the movable screw 35 is connected to the inner thread of the fixing frame 30, the rotation of the movable screw 35 will drive the movable plate 31 and its fixed rod 39 to slide within the fixing frame 30. The sliding of the fixed rod 39 will drive the fixed top head 37 to move closer to the workpiece, and cooperate with the positioning baffle 6 until the workpiece is tightly clamped. During the clamping process, the positioning accuracy of the workpiece can be ensured by observation or measurement. When it is necessary to release the workpiece, simply rotate the knob 33 in the opposite direction, and the movable plate 31 and its fixed rod 39 will slide in the opposite direction under the drive of the movable screw 35, thereby releasing the workpiece. In addition, the design of the clamping groove 36 and the clamping handle 38 can further increase the stability of the movable screw 35 after clamping, avoid loosening, and ensure the stability during the processing.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
