Description

Technical Field

[0001] This utility model relates to the field of anodizing equipment technology, specifically to an anodizing fixture. Background Technology

[0002] Aluminum parts are widely used in the industrial field and are a basic material for both military and civilian industries. However, aluminum parts are easily corroded when exposed to air for a long time. Anodizing aluminum parts to form a dense oxide film on their surface can significantly improve their corrosion resistance and wear resistance. Using aluminum alloy parts as the anode, an electrolytic method is used to form an oxide film on its surface. The metal oxide film changes the surface state and properties, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface.

[0003] Anodizing of aluminum parts is now widely used in the market. Anodizing aluminum parts involves placing the anodized aluminum parts and their alloys in a suitable electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and electrolyzing them under specific conditions and applied current. The aluminum parts need to withstand high voltage and current during the anodizing process, so it is essential to ensure that the clamping fixture maintains good contact with the aluminum parts. However, most aluminum parts anodizing fixtures are fixedly installed and cannot be adjusted according to the size of the aluminum parts during use, which limits their application. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hanger for anodizing, comprising a device base, on which two symmetrical support columns are mounted, and a common top mounting plate is mounted on the top of the two support columns. A transmission cavity is formed in the top mounting plate, and a drive gear is rotatably mounted in the transmission cavity. A servo motor is mounted on the top of the top mounting plate, and the output shaft of the servo motor is mounted on the drive gear. Two transmission sliders are slidably mounted in the transmission cavity, and each of the two transmission sliders has a tooth groove that meshes with the drive gear. Mounting blocks are mounted at the bottom of the two transmission sliders and at the center of the bottom of the top mounting plate. A hanger bracket is mounted on the mounting block, and several hanging rods are arranged at intervals on the hanger bracket.

[0008] Preferably, two symmetrical rectangular sliding holes are provided on the bottom inner wall of the transmission cavity, and the bottoms of the two transmission sliders pass through the two rectangular sliding holes and are connected to the mounting block.

[0009] Preferably, the mounting block has a mating groove, and the top of the hanger bracket is provided with a mating block that matches the mating groove. The mating groove and the mating block are connected and fixed by fixing bolts.

[0010] Preferably, the top of the device base is provided with a guide groove, and three guide sliders are slidably arranged in the guide groove. The three guide sliders are respectively installed at the bottom of three hanger brackets.

[0011] Preferably, a guide slide rod is arranged in the guide groove, and a sliding hole adapted to the guide slide rod is opened on the guide slide block.

[0012] Preferably, two mutually symmetrical limiting grooves are formed on the inner wall of the transmission cavity, and limiting sliders are slidably arranged in the limiting grooves. The two limiting sliders are respectively installed on the two transmission sliders.

[0014] Compared with the prior art, the present invention provides a fixture for anodizing, which has the following advantages:

[0015] This invention utilizes a combination of transmission sliders, drive gears, hanger brackets, and hanger rods. When hanging aluminum parts of different sizes, a servo motor drives the drive gear to rotate, causing the two transmission sliders to move closer or further apart. This, in turn, causes the two mounting blocks to move closer or further apart, thus adjusting the distance between the hanger brackets on the left and right sides and the central hanger bracket. This allows the device to accommodate aluminum parts of different sizes, improving its adaptability. Furthermore, the use of connecting blocks and grooves facilitates the replacement of hanger brackets with different models of hanger rods for different aluminum parts, further enhancing the device's adaptability.

The top of the two support columns 4 is mounted on the same top mounting plate 2. A transmission cavity 9 is opened in the top mounting plate 2. A drive gear 10 is rotatably mounted in the transmission cavity 9. A servo motor 3 is mounted on the top of the top mounting plate 2. The actuation output shaft of the servo motor 3 is mounted on the drive gear 10. Two transmission sliders 11 are slidably mounted in the transmission cavity 9. Both transmission sliders 11 have tooth grooves 13 that mesh with the drive gear 10. Mounting blocks 14 are installed at the bottom of the two transmission sliders 11 and at the center of the bottom of the top mounting plate 2. A fixture bracket 5 is mounted on the mounting block 14. Several hanging rods 8 are arranged at intervals on the fixture bracket 5.

[0025] By employing the coordinated structure of the transmission slider 11, drive gear 10, hanger bracket 5, and hanger rod 8, the drive gear 10 can be rotated by the servo motor 3 when hanging aluminum parts of different sizes. This causes the two transmission sliders 11 to move closer or further apart, which in turn causes the two mounting blocks 14 to move closer or further apart. This allows for adjustment of the distance between the hanger brackets 5 on the left and right sides and the hanger bracket 5 in the middle of the device, enabling the device to adapt to aluminum parts of different sizes and improving its adaptability. Furthermore, the docking block 19 and docking groove 18 facilitate the replacement of hanger brackets 5 with different models of hanger rods 8 according to different aluminum parts, further enhancing the adaptability of the device.

[0026] Specifically, in this embodiment, two symmetrical rectangular sliding holes 12 are provided on the bottom inner wall of the transmission cavity 9, and the bottoms of the two transmission sliders 11 pass through the two rectangular sliding holes 12 respectively and are connected to the mounting block 14.

[0027] The rectangular sliding hole 12 can be used to limit the movement range of the transmission slider 11 and the mounting block 14.

[0028] Specifically, in this embodiment, the mounting block 14 is provided with a docking groove 18, and the top of the hanger bracket 5 is provided with a docking block 19 that is adapted to the docking groove 18. The docking groove 18 and the docking block 19 are connected and fixed by fixing bolts 6.

[0029] The interaction between the docking block 19 and the docking groove 18 facilitates the replacement of different models of hanging rods 8 with the hanging bracket 5 according to different aluminum parts, further improving the adaptability of the device.

[0030] Specifically, in this embodiment, a guide groove 16 is provided on the top of the device base 1, and three guide sliders 17 are slidably arranged in the guide groove 16. The three guide sliders 17 are respectively installed at the bottom of the three hanger brackets 5. A guide rod 20 is arranged in the guide groove 16, and a sliding hole 15 adapted to the guide rod 20 is provided on the guide slider 17.

[0031] The guide groove 16, guide slider 17 and guide rod 20 work together to guide the movement direction of the hanger bracket 5 and ensure the stability of the hanger bracket 5 during movement to a certain extent.

[0032] Specifically, in this embodiment, two mutually symmetrical limiting grooves are provided on the inner wall of the transmission cavity 9, and limiting sliders are slidably arranged in the limiting grooves. The two limiting sliders are respectively installed on the two transmission sliders 11.

[0033] By cooperating with the limiting slide, the moving direction and range of the transmission slider 11 can be limited.

[0034] Specifically, in this embodiment, four movable wheels 7 arranged in a matrix are installed at the bottom of the device base 1, which facilitates the movement of the device and ensures its mobility.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
