[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-3This utility model provides a technical solution: a deformation-resistant fixing fixture for machining aluminum cast automotive parts housings, including a base 1. A horizontal adjustment mechanism is provided on both sides of the top of the base 1. The horizontal adjustment mechanism includes a side plate 2. A side plate 2 is fixed on both sides of the top of the base 1. A first lead screw 3 is threaded through the middle of the side plate 2. A first handle 4 is fixed to one end of the first lead screw 3. The other end of the first lead screw 3 is rotatably connected to the middle of a movable plate 5 via a bearing. The bottom of the movable plate 5 is in contact with the top of the base 1. A guide rod 6 is fixed to one end of the movable plate 5. The end of the guide rod 6 penetrates the interior of the side plate 2. An up-and-down adjustment mechanism is provided on the movable plate 5, and a clamping mechanism is provided on the up-and-down adjustment mechanism.

[0019] The up-down adjustment mechanism includes a through groove 7. The inside of the movable plate 5 is provided with a through groove 7. A movable block 8 is installed inside the through groove 7. The lower end of the second lead screw 9 is rotatably installed at the center of the top of the movable block 8 via a bearing. The upper end of the second lead screw 9 passes through the top of the movable plate 5 and is fixed with a second handle 10. The second lead screw 9 is threadedly connected to the movable plate 5.

[0020] The clamping mechanism includes a third lead screw 11. The third lead screw 11 is threaded through the interior of the movable block 8. Rubber blocks 12 and third handles 13 are fixed to both ends of the third lead screw 11, respectively. The rubber blocks 12 are located near the center of the base 1. The through groove 7, movable block 8, second lead screw 9, second handle 10, third lead screw 11, rubber blocks 12, and third handles 13 are all symmetrically distributed about the central axis of the movable plate 5. The through groove 7 and movable block 8 are both designed as rectangular structures when viewed from above. The movable block 8 and the through groove 7 form a sliding connection. Under the limitation of the through groove 7, the height of the movable block 8 can be adjusted when the second lead screw 9 is rotated forward or backward, thereby adjusting the height of the third lead screw 11. This allows the end of the third lead screw 11 to contact the center of the aluminum cast automotive part housing, ensuring the fixing effect of the aluminum cast automotive part and reducing the probability of deformation of the aluminum cast automotive part.

[0021] The guide rods 6 are symmetrically distributed about the central axis of the movable plate 5, and the guide rods 6 are slidably connected to the side plate 2. Under the guidance of the guide rods 6, the movable plate 5 can move horizontally, thereby adjusting the distance between the third lead screws 11, so that the third lead screws 11 can clamp the housing of cast automotive parts of different sizes.

[0022] Working principle: When using this aluminum cast automotive part housing to process the anti-deformation fixing fixture, first place the aluminum cast automotive part housing at the center of the top of the base 1, then rotate the first handle 4, the first handle 4 drives the first lead screw 3 to rotate. Since the first lead screw 3 is threadedly connected to the side plate 2, and the guide rod 6 is slidably connected to the side plate 2, and the other end of the first lead screw 3 is rotatably connected to the middle of the movable plate 5 through the bearing, the movable plate 5 and the third lead screw 11 move closer to the aluminum cast automotive part housing. After the position of the movable plate 5 is adjusted;

[0023] Next, rotate the second handle 10, which drives the second lead screw 9 to rotate. Since the second lead screw 9 is threadedly connected to the movable plate 5, and both the through groove 7 and the movable block 8 are designed as rectangular structures from a top view, and the movable block 8 and the through groove 7 are slidably connected, and the lower end of the second lead screw 9 is rotatably mounted at the center of the top of the movable block 8 through a bearing, the second lead screw 9 can drive the movable block 8 and the third lead screw 11 to move upward or downward. When the end of the third lead screw 11 is aligned with the middle of the aluminum cast automotive part housing, rotate the two third handles 13 on the left movable plate 5, so that the two third handles 13 drive the two third lead screws 11 to rotate. Since the third lead screw 11 and the movable block 8 are threadedly connected, the rubber blocks 12 at the ends of the two third lead screws 11 on the left side contact the outside of the aluminum cast automotive part housing. Similarly, the rubber blocks 12 at the ends of the two third lead screws 11 on the right side are in close contact with the outside of the aluminum cast automotive part housing, thus completing the fixation of the aluminum cast automotive part housing.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
