Technical Field

[0001] The utility model belongs to the technical field of die-casting aluminum alloy processing equipment, and specifically relates to an anodizing device for die-casting aluminum alloy. Background Technique

[0002] Die-cast aluminum alloy products are mainly used in industries such as electronics, automobiles, motors, household appliances, and some communication industries. Some high-performance, high-precision, and high-toughness high-quality aluminum alloy products are also used in industries with relatively high requirements such as large aircraft and ships.

[0003] In the process of die-casting aluminum alloy production and manufacturing, it is necessary to use an aluminum alloy product as an anode and place it in an electrolyte solution. By using electrolysis, an alumina film is formed on its surface to protect the die-cast aluminum alloy product. Therefore, a corresponding anodizing device is required. However, in the actual use process of the existing anodizing device, clamping tools are needed to clamp and hang the aluminum alloy product in the oxidation tank. However, due to the close contact between the clamping tool and the aluminum alloy product, the contact part between the two is not easily oxidized. It is necessary for the operator to take out the die-cast aluminum alloy product, change the clamping position, and then put it into the oxidation tank again for secondary oxidation operation. This method is both time-consuming and laborious, so it needs to be improved. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Such as Figures 1 to 5As shown in the figure, the utility model provides an anodic oxidation device for die-cast aluminum alloy, which includes a fixing plate 1. At the top of the left side of the front end of the fixing plate 1, a fixing block 2 is fixedly installed. On the right side inside the fixing block 2, a movable block 3 is movably sleeved. The right end of the movable block 3 penetrates through the fixing block 2 and extends to the outside of the fixing block 2. On the right side of the bottom end of the movable block 3, a vertical plate 4 is fixedly installed. The top of the left end of the vertical plate 4 is movably connected to the right end of the fixing block 2. Inside the vertical plate 4, a positioning plate 5 is fixedly sleeved. At the bottom end of the vertical plate 4, a clamping block 6 is fixedly installed. On the right end of the fixing plate 1, a positioning block 7 is fixedly installed on the right side of the clamping block 6. At the top inside the fixing block 2, a limiting rod 8 is fixedly sleeved. On the outer surface of the limiting rod 8, a vertical block 9 is movably sleeved. The bottom end of the vertical block 9 is fixedly connected to the left side of the top end of the movable block 3. At the top of the left side of the rear end of the fixing plate 1, a driving motor 10 is fixedly installed. At the other end of the output shaft of the driving motor 10, a driving shaft 11 is fixedly sleeved. The front end of the driving shaft 11 penetrates through the fixing plate 1 and extends to the outside of the fixing plate 1 and is fixedly sleeved with a rotating plate 12. The outer surface of the rotating plate 12 is movably sleeved with the inner surface of the vertical block 9. Inside the rotating plate 12, a round rod 13 is movably sleeved. The outer surface of the round rod 13 is fixedly sleeved with the inner surface of the vertical block 9.

[0024] When the driving motor 10 is started, it will cause the driving shaft 11 to drive the rotating plate 12 to rotate, so that a thrust is generated on the outer surface of the round rod 13 by the inner surface of the rotating plate 12, pushing the round rod 13 to drive the vertical block 9 and the movable block 3 to move along the outer surface of the limiting rod 8, so that the movable block 3 drives the clamping block 6 to move through the vertical plate 4, and then cooperates with the positioning block 7 to clamp and fix the die-cast aluminum alloy. By moving the clamping block 6 left and right, under the action of gravity, different positions of the die-cast aluminum alloy can be clamped and fixed, so that the secondary oxidation operation is not required.

[0025] Reference Figures 1 to 5 As shown in the figure, at the top of the front end of the fixing plate 1, a cross plate 14 is fixedly installed below the driving motor 10. Inside the cross plate 14, a limiting plate 15 is movably sleeved. At the bottom of the rear end of the limiting plate 15, an oxidation tank 16 is fixedly installed.

[0026] As a technical optimization scheme of the utility model, the existence of the cross plate 14 and the limiting plate 15 will limit the movement of the fixing plate 1.

[0027] Reference Figures 1 to 4 As shown in the figure, on the left and right sides of the top end of the oxidation tank 16, fixing frames 17 are respectively fixedly installed. Inside the fixing frames 17, cathode plates 18 are fixedly sleeved.

[0028] As a technical optimization scheme of the utility model, due to the existence of the cathode plates 18, the oxidation operation on the outer surface of the die-cast aluminum alloy is realized.

[0029] Reference Figures 2 to 4, a bracket 19 is fixedly installed at the top of the front end of the oxidation tank 16. A limiting groove 20 is opened on the left side of the front end of the bracket 19, and a limiting block 21 is movably sleeved at the right end inside the limiting groove 20.

[0030] As a technical optimization scheme of the present utility model, the inner surface of the limiting groove 20 and the outer surface of the limiting block 21 are both smooth, ensuring that the limiting block 21 will not get stuck when moving along the inside of the limiting groove 20.

[0031] Reference Figures 1 to 4 , a power motor 22 is fixedly installed at the left end of the bracket 19, and the other end of the output shaft of the power motor 22 is fixedly sleeved with a threaded rod 23.

[0032] As a technical optimization scheme of the present utility model, when the power motor 22 is started, the threaded rod 23 will rotate.

[0033] Reference Figures 2 to 5 , a rectangular block 24 is threadedly sleeved on the right side of the outer surface of the threaded rod 23. The bottom end of the rectangular block 24 is fixedly connected to the top end of the limiting block 21. The top end of the rectangular block 24 is hinged with a connecting rod 25, and the other end of the connecting rod 25 is hinged to the front side of the bottom end of the cross plate 14.

[0034] As a technical optimization scheme of the present utility model, when the rectangular block 24 drives the connecting rod 25 to move, a pulling force will be generated on the other end of the connecting rod 25 on the cross plate 14, pulling the cross plate 14 to move.

[0035] Reference Figure 1 and Figure 2 , a drain pipe 26 is fixedly sleeved at the bottom of the right inner wall of the oxidation tank 16. The right end of the drain pipe 26 penetrates through the oxidation tank 16 and extends to the outside of the oxidation tank 16 and is threadedly sleeved with a sealing cover 27.

[0036] As a technical optimization scheme of the present utility model, when the sealing cover 27 is opened, the solution inside the oxidation tank 16 will be discharged from the drain pipe 26.

[0037] Reference Figures 1 to 4 , four corner edges at the bottom end of the oxidation tank 16 are respectively movably installed with universal wheels 28. The number of the universal wheels 28 is four and they are respectively centrosymmetric about the center of the oxidation tank 16.

[0038] As a technical optimization scheme of the present utility model, due to the existence of the universal wheels 28, it will be convenient to move the oxidation tank 16.

[0039] The working principle and usage process of the present utility model:

[0040] First, the operator places the die-cast aluminum alloy product inside the positioning block 7 and makes the top end of the die-cast aluminum alloy product contact the positioning plate 5. Subsequently, the operator starts the driving motor 10, causing the driving shaft 11 to drive the rotating plate 12 to rotate. At this time, the inner wall of the rotating plate 12 will generate a thrust on the outer surface of the round rod 13, pushing the round rod 13 to drive the movable block 3, the vertical plate 4, and the clamping block 6 to move to the right through the vertical block 9, so as to cooperate with the positioning block 7 to clamp and fix the die-cast aluminum alloy product. Then, the operator can put the die-cast aluminum alloy product into the oxidation tank 16 for oxidation operation. When the oxidation is completed, the operator starts the driving motor 10 to release the clamping of the die-cast aluminum alloy product by the clamping block 6. At this time, under the action of gravity, the die-cast aluminum alloy product will move downward along the inner surface of the positioning block 7. When the initial contact part between the die-cast aluminum alloy product and the clamping block 6 is completely exposed, start the driving motor 10 again to make the clamping block 6 clamp the die-cast aluminum alloy product again. In this way, the oxidation operation can be continued to complete the oxidation of the initial clamping part of the die-cast aluminum alloy product. With the mutual cooperation of each mechanism, the operator does not need to take out the die-cast aluminum alloy product and adjust the clamping part during the oxidation process and then perform secondary oxidation, thus improving the working efficiency of the anodic oxidation device.

[0041] When the operator starts the power motor 22, the threaded rod 23 will rotate. At this time, the rectangular block 24 threadedly sleeved on the threaded rod 23 will drive the limiting block 21 and the bottom end of the connecting rod 25 to move along the inner surface of the limiting groove 20, so that the top end of the connecting rod 25 generates a pulling force on the cross plate 14, pulling the cross plate 14 to drive the fixed plate 1 to move downward along the outer surface of the limiting plate 15 until the die-cast aluminum alloy product is immersed in the solution inside the oxidation tank 16. In this way, the automatic loading and unloading of the die-cast aluminum alloy product can be realized, reducing the contact between the operator and the solution inside the oxidation tank 16, and thus improving the safety of using the anodic oxidation device.
