[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an anodizing coating fixture for aluminum alloy parts, including a support frame 1, a base at the bottom of the support frame 1, a mounting plate 3 at the top of the support frame 1, symmetrical hooks 4 fixedly mounted on one side of the mounting plate 3, two support plates 2 between the inner walls of the support frame 1, and adjustment structures at both ends of the support frame 1 for moving one of the support plates 2 up and down. Support components are also provided on the two support plates 2.

[0025] refer to Figure 1 , Figure 2 and Figure 3The adjustment structure includes an L-shaped support block 5 installed on one side wall of the support frame 1. A drive shaft 6 is rotatably installed in a shaft hole in the side wall of the L-shaped support block 5. One end of the drive shaft 6 is connected to a handle, and the other end of the drive shaft 6 is connected to a bearing seat on one side wall of the support frame 1. A drive gear 7 is also provided on the drive shaft 6. The drive gear 7 meshes with a drive rack 8 provided in a sliding frame located at the edge of the L-shaped support block 5 on one side wall of the support frame 1. One end of a support plate 2 is provided with a connecting block 9. One end of the connecting block 9 passes through a groove between one side wall of the support frame 1 and the sliding frame and is connected to one side of the drive rack 8. The other end of the support plate 2 is provided with an L-shaped slider 10. The L-shaped slider 10 slides on a slide rod 12 installed inside a fixed frame 11 on the other side wall of the support frame 1. Several corresponding fixing holes are provided between the fixed frame 11 and one side wall of the support frame 1. A pin is provided in one of the fixing holes. 13. One end of the pin 13 passes through the fixing hole opened on the side wall of the L-shaped slider 10. More specifically, by having the connecting block 9 at one end of one of the support plates 2 pass through the groove opened between the support frame 1 and the sliding frame and connect with the transmission rack 8, the L-shaped slider 10 at the other end of the support plate 2 slides on the slide rod 12. By rotating the handle, the transmission shaft 6 drives the transmission gear 7 to rotate, and the transmission gear 7 drives the transmission rack 8 to slide up and down along the sliding frame, thereby enabling the support plate 2 to move up and down to adjust its height, so as to accommodate aluminum alloy parts of different heights. Then, by inserting the pin 13 into the corresponding fixing hole between the fixing frame 11 and the support frame 1, and passing through the fixing hole opened on the L-shaped slider 10, the position of the support plate 2 is fixed, so as to adjust the distance between the support plates 2 according to the size of different specifications of aluminum alloy parts, so as to accommodate different specifications of aluminum alloy parts and improve practicality.

[0026] refer to Figure 3 and Figure 4The support assembly includes a fixing rod 14 installed in a groove on the top of the support plate 2. Multiple sliding seats 15 are provided on the fixing rod 14. Both ends of the sliding seats 15 pass through openings on both sides of the support plate 2 and are connected to a support rod 16. A hook 17 is provided on the support rod 16. A lever is provided on the top of the sliding seat 15. A corresponding limiting hole is also provided at the limiting groove 18 on the support plate 2 at the top of the sliding seat 15. A limiting bolt 19 is provided in the limiting hole, and a clamping plate 20 is provided on the limiting bolt 19. More specifically, by pushing the lever on the top of one of the sliding seats 15 on the support plate 2, the sliding seat 15 moves along... The fixed rod 14 slides, causing the two ends of the sliding seat 15 to slide within the openings on both sides of the support plate 2. This moves the support rods 16 and hooks 17 connected at both ends to adjust their positions, thereby adjusting the width between the sliding seat 15 and the support rods 16 and hooks 17 connected at both ends on the other support plate 2. Once the width is adjusted, the limiting bolt 19 is passed through the limiting groove 18 on the support plate 2 and matched with the limiting hole on the sliding seat 15. The clamping plate 20 is then pressed against the top of the support plate 2, thereby limiting and fixing the sliding seat 15. This facilitates the support of aluminum alloy parts of different widths, further improving its practicality.

[0027] refer to Figure 5 The two hooks 4 are equipped with limiting components inside. The limiting components include an L-shaped limiting plate 21. Two symmetrical connecting rods 22 are connected to one side of the L-shaped limiting plate 21. One end of the two connecting rods 22 passes through a through hole in the side wall of the hook 4 and is connected to a pull plate 23. A spring 24 is also connected to one side of the L-shaped limiting plate 21. The spring 24 is looped around the outer wall of the connecting rod 22 and the other end is connected to the inner wall of the hook 4. More specifically, when the support frame 1 is hung in the designated position, the connecting rod 22 and the L-shaped limiting plate 21 are contracted by pulling the pull plate 23, which compresses the spring 24. Then the hook 4 is hooked. At this time, the pull plate 23 is released, and the connecting rod 22 and the L-shaped limiting plate 21 will return to their original position under the action of the spring 24, so that the L-shaped limiting plate 21 can press against the hanging position to prevent shaking.

[0028] The implementation principle of the aluminum alloy anodizing coating fixture in this application embodiment is as follows: When performing anodizing coating on aluminum alloy parts, the operator first rotates the handle according to the specifications of the aluminum alloy parts, causing the transmission shaft 6 to drive the transmission gear 7 to rotate, so that the transmission gear 7 drives the transmission rack 8 to slide up and down along the sliding frame, thereby driving the support plate 2 to move up and down to adjust the height, so as to accommodate aluminum alloy parts of different heights. Then, the pin 13 is inserted into the corresponding fixing hole between the fixing frame 11 and the support frame 1, and passes through the fixing hole opened on the L-shaped slider 10, so that the position of the support plate 2 is fixed. Then, the sliding seat 15 on one of the support plates 2 is pushed to slide along the fixing rod 14, so that the sliding seat 15 drives the support rods connected at both ends. The positions of the support rod 16 and the support hook 17 are adjusted to adjust the width between them and the support rod 16 and the support hook 17 connected to the two ends of the sliding seat 15 on the other support plate 2. After the width is adjusted, the sliding seat 15 is fixed by the limit bolt 19 and the clamping plate 20, so that the workers can easily support aluminum alloy parts of different widths and improve the practicality. Then, the pull plate 23 is pulled to drive the connecting rod 22 and the L-shaped limit plate 21 to retract and squeeze the spring 24, so that the hook 4 at the top of the support frame 1 is hooked on the external copper busbar. At this time, the pull plate 23 is released, and the connecting rod 22 and the L-shaped limit plate 21 will be restored under the action of the spring 24, so that the L-shaped limit plate 21 can be pressed against the hook position to prevent shaking.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
