Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and in particular to a hanger for anodizing aluminum products. Background Technology

[0002] A mounting rack for anodizing aluminum products is a specialized device designed for mounting and securing aluminum products during the anodizing process. These racks are typically made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel or high-strength plastics, to withstand the corrosive effects of the electrolyte and temperature variations during anodizing. The rack design prioritizes the stable placement of the aluminum products, ensuring they are evenly subjected to the current during oxidation and preventing uneven oxidation due to poor contact. The rack structure is usually adjustable to accommodate aluminum products of different sizes and shapes, and provides sufficient clearance between multiple aluminum pieces to ensure the flow of the anodizing liquid and the smooth progress of the electrolytic reaction.

[0003] Patent CN217781300U discloses a hanger for anodizing aluminum products. Specifically, the patent discloses a technical solution comprising an outer frame, a positioning cylinder on the inner side of the outer frame, an inner cylinder fixedly connected to one side of the positioning cylinder, a positioning rod slidably connected to the inner wall of the inner cylinder, a pad fixedly connected to one end of the positioning rod, and a first positioning ring fixedly connected to one end of the positioning rod. This achieves the technical effect of "a first spring driving a locking block downwards, the locking block driving one side of a rope downwards via a second positioning ring, the rope driving three first positioning rings, and then the three first positioning rings driving three pads, with the first spring providing tension to the rope, causing the three pads to press against the surface of the parts, thereby pressing and fixing parts of different shapes. This solves the problem of existing aluminum product anodizing hangers requiring different clamps for clamping, making them difficult to use interchangeably, and requiring the installation of corresponding hangers according to the shape, thus reducing the practicality of the hanger."

[0004] In existing devices, the pad directly contacts the part for clamping. After long-term use, the surface of the pad may become smooth due to frequent friction, resulting in reduced friction between the pad and the part, unstable clamping, and the part is prone to loosening or even falling off during the anodizing process.

[0005] Therefore, we propose a fixture for anodizing aluminum products. Utility Model Content

[0027] Example

[0028] like Figure 1-5As shown, this utility model provides a technical solution: a hanger for anodizing aluminum products, including a support frame 1, which serves as the basic support structure for the entire hanger, providing installation positions for other components and ensuring the stability of the entire device. The support frame 1 has a first fixing plate 2 and a second fixing plate 3 inside. A connecting handle 6 is movably connected to the corresponding side of the first fixing plate 2 and the second fixing plate 3, serving to connect the clamping disc 5 and the fixing plate, allowing the clamping disc 5 to be installed in a suitable position. The clamping disc 5 is fixedly installed at the bottom of the connecting handle 6, serving as a rotating component, a quick-release component, and a fixing component. The mounting carrier for the component has a rotating component inside that can drive the clamping rod 12 to rotate, thereby clamping and fixing the aluminum product on the clamping block 13. The clamping disk 5 has a rotating component inside, and the bottom of the rotating component has a clamping rod 12. The clamping rod 12 has a quick-release component inside, and the side of the quick-release component away from the clamping rod 12 has a clamping block 13. The outer periphery of the clamping block 13 has a coating to increase friction and prevent the clamping from loosening due to long-term oxidation. The top of the clamping disk 5 has a fixing component, and the side of the fixing component away from the clamping disk 5 cooperates with the connecting handle 6.

[0029] The support frame 1 has sliding grooves on both sides inside, providing a track for the up and down movement of the first fixed plate 2, allowing the first fixed plate 2 to be adjusted in position within the support frame 1. The first fixed plate 2 is slidably connected inside the sliding grooves. A second fixed plate 3 is provided at the bottom of the first fixed plate 2 and is fixedly installed inside the support frame 1. A threaded hole is provided at the bottom of the second fixed plate 3. Screws 4 are provided on both sides of the first fixed plate 2. The screws 4 pass through the first fixed plate 2 and are threaded into the threaded holes at the bottom of the second fixed plate 3, allowing the distance between the first fixed plate 2 and the second fixed plate 3 to be adjusted, thereby adjusting the first fixed plate 2 to fix and release the entire hanger. The screws 4 pass through the first fixed plate 2 and are threaded into the interior of the second fixed plate 3.

[0030] The rotating assembly includes a cylinder 7, a rack 8, and a gear 9. The cylinder 7 is fixedly installed inside the clamping disk 5, serving as the power source for the rotating assembly. The output end of the cylinder 7 is fixedly connected to the rack 8. When the rack 8 moves linearly under the drive of the cylinder 7, it drives the gear 9 to rotate around its axis. A gear 9 is provided on one side of the rack 8, and the teeth of the gear 9 mesh with those of the rack 8. The gear 9 is rotatably connected inside the clamping disk 5. When the gear 9 rotates, the clamping rod 12 moves within the moving groove inside the gear 9. At the same time, the slide rail 10 and the slider 11 serve as guides and limiters, ensuring that the clamping rod 12 can only move in a specific direction, thus allowing the clamping rod 12 to rotate. The movement is more stable and accurate, allowing the clamping block 13 to better fix the aluminum product. The rotating assembly also includes a slide rail 10, a slider 11 and a connecting rod 14. The slide rail 10 is fixedly installed inside the clamping plate 5. The slider 11 is slidably connected inside the slide rail 10. The bottom of the slider 11 is fixedly connected to the connecting rod 14. When the gear 9 rotates under the drive of the rack 8, the trajectory of the moving groove forces the connecting rod 14 to drive the slider 11 to move in a straight line along the slide rail 10. At the same time, the clamping rod 12 moves together with the connecting rod 14. The end of the connecting rod 14 away from the slider 11 is fixedly connected to the clamping rod 12. The gear 9 has multiple sets of moving grooves inside, and the connecting rod 14 is slidably connected inside the moving grooves.

[0031] The quick-release assembly includes a quick-release head 15, a quick-release seat 16, and a connecting collar 17. The quick-release head 15 is fixedly connected inside the clamping rod 12. Both ends of the quick-release head 15 have protruding structures. The end of the quick-release head 15 away from the clamping rod 12 is provided with the quick-release seat 16. The quick-release seat 16 has grooves on both sides. The protruding structures of the quick-release head 15 are adapted to the grooves of the quick-release seat 16. This design allows the quick-release head 15 and the quick-release seat 16 to quickly and accurately align. The connecting collar 17 is slidably connected to the outer periphery of the quick-release head 15. The end of the quick-release seat 16 away from the quick-release head 15 is fixedly connected to the clamping block 13. When the clamping block 13 needs to be installed, the protruding structure of the quick-release head 15 is aligned with the groove of the quick-release seat 16 and inserted. Then, the connecting collar 17 is slidably inserted so that it fits on the connection part between the quick-release head 15 and the quick-release seat 16, which serves to fix them and prevent them from separating.

[0032] The fixing assembly includes a locking strip 18, a spring 19, a fastening rod 20, and a handle 21. The locking strip 18 is rotatably connected to the top of the clamping disc 5. One end of the spring 19 is fixedly installed inside the connecting handle 6. The end of the spring 19 away from the connecting handle 6 is fixedly connected to one end of the fastening rod 20. The fastening rod 20 is slidably connected inside the connecting handle 6. When it is necessary to fix the connecting handle 6, the locking strip 18 is rotated to engage with the fastening rod 20. The spring 19 is in a stretched state, allowing the fastening rod 20 to fix the locking strip 18 to the connecting handle 6. The fastening rod 20 engages with the locking strip 18. The end of the fastening rod 20 away from the locking strip 18 is rotatably connected to the handle 21. When it is necessary to adjust the position of the connecting handle 6, the handle 21 is rotated. The handle 21 drives the fastening rod 20 to slide inside the connecting handle 6, causing the fastening rod 20 to disengage from the locking strip 18.

[0033] The working process of this utility model:

[0034] Step 1: The support frame 1 serves as the basic support structure for the entire hanger, providing installation positions for other components. The first fixing plate 2 is placed into the sliding grooves on both sides inside the support frame 1, allowing the first fixing plate 2 to move up and down along the sliding grooves. The second fixing plate 3 is fixedly installed inside the support frame 1, located at the bottom of the first fixing plate 2. By rotating the screws 4 on both sides of the first fixing plate 2, the screws 4 pass through the first fixing plate 2 and are threaded into the threaded holes at the bottom of the second fixing plate 3. When the screws 4 are rotated clockwise, the distance between the first fixing plate 2 and the second fixing plate 3 decreases; when the screws 4 are rotated counterclockwise, the distance between them increases. After adjusting the distance according to actual needs, the first fixing plate 2 achieves the initial fixation of the entire hanger. The connecting handle 6 serves to connect the clamping plate 5 and the fixing plate. The clamping plate 5 is fixedly installed at its bottom. The connecting handle 6 is installed on the corresponding side of the first fixing plate 2 and the second fixing plate 3, so that the clamping plate 5 is in a suitable position, providing a foundation for the subsequent installation of other components.

[0035] Step two: The rotating assembly is installed inside the clamping disk 5. The cylinder 7, as the power source, is fixedly installed inside the clamping disk 5, and its output end is fixedly connected to the rack 8. When the cylinder 7 is activated, the output end performs a linear extension and retraction motion, driving the rack 8 to move in a straight line. Since the gear 9 on one side of the rack 8 meshes with the tooth surface of the rack 8, the linear movement of the rack 8 will drive the gear 9 to rotate around its axis. The gear 9 is rotatably connected inside the clamping disk 5, and multiple sets of moving grooves are opened inside the gear 9. The slide rail 10 is fixedly installed inside the clamping disk 5, and the slider 11 is slidably connected inside the slide rail 10. The bottom of the slider 11 is fixedly connected to the clamping rod 12 through the connecting rod 14. The connecting rod 14 is slidably connected to the gear 9. When gear 9 rotates, the trajectory of the moving groove forces connecting rod 14 to drive slider 11 to move linearly along slide rail 10. At the same time, clamping rod 12 moves together with connecting rod 14. Slide rail 10 and slider 11 play a guiding and limiting role, ensuring that clamping rod 12 can only move smoothly and accurately in a specific direction. Clamping rod 12 is provided with quick release assembly. Clamping block 13 is provided on the side of quick release assembly away from clamping rod 12. The outer periphery of clamping block 13 is coated to increase friction and prevent clamping from loosening under long-term oxidation. As clamping rod 12 moves, clamping block 13 gradually approaches aluminum product and finally clamps and fixes aluminum product.

[0036] Step 3: The fixing assembly is set on the top of the clamping plate 5. The locking strip 18 is rotatably connected to the top of the clamping plate 5. One end of the spring 19 is fixedly installed inside the connecting handle 6, and the other end is fixedly connected to one end of the fastening rod 20. The fastening rod 20 is slidably connected inside the connecting handle 6. The end of the fastening rod 20 away from the locking strip 18 is rotatably connected to the handle 21. In the initial state, the spring 19 is in its natural state, and the fastening rod 20 and the locking strip 18 are not engaged. When it is necessary to fix the connecting handle 6, rotate the locking strip 18 to make it in the appropriate position, and then pull the handle 21. The handle 21 causes the fastening rod 20 to slide inside the connecting handle 6. At the same time, the spring 19 is stretched, aligning the fastening rod 20 and the locking strip 18. Release the handle 21. The elasticity of the spring 19 causes the fastening rod 20 to fix the locking strip 18 and the connecting handle 6, thereby fixing the entire clamping system to the connecting frame and preventing... Long-term use causes wear and tear on the device, leading to loosening of the connection parts. When it is necessary to adjust the position of the connecting handle 6, pull the handle 21. The handle 21 drives the fastening rod 20 to slide inside the connecting handle 6, causing the fastening rod 20 to disengage from the locking strip 18. At this time, the locking strip 18 can be rotated and the connecting handle 6 moved to adjust it to a suitable position. Then, the connecting handle 6 can be fixed again according to the above steps. If the clamping block 13 is damaged in the anodized environment, it needs to be replaced easily. Slide the connecting collar 17 to disengage it from the connection between the quick-release head 15 and the quick-release seat 16. Then pull out the quick-release head 15 to remove the original clamping block 13. Align the quick-release seat 16 on the new clamping block 13 with the protruding structure of the quick-release head 15 and insert it. Then slide the connecting collar 17 to fit it on the connection between the quick-release head 15 and the quick-release seat 16 to fix it and complete the replacement of the clamping block 13.
