AI Technical Summary
Existing aluminum profile anodizing fixtures cause a shift in the center of gravity when fixing shorter aluminum profiles, resulting in uneven electrolyte flow, uneven oxide film formation speed and thickness, and affecting the quality of the oxide film.
A stable aluminum profile anodizing fixture was designed. By setting T-shaped grooves and T-shaped sliders on the top plate, and connecting clamping mechanisms on the vertical rod, the spacing of the clamping mechanisms is adjusted by a displacement mechanism, and the vertical rod is moved by worm gear, worm wheel and gear transmission, ensuring that the center of gravity of the fixture is located on the main shaft axis and keeping the aluminum profile in a horizontal state.
This effectively avoids the problem of uneven oxide film formation in aluminum profiles during the anodizing process, and improves the quality and consistency of oxide film formation.

Abstract
Description
Technical Field
[0001] This utility model relates to an anodizing fixture, specifically, to an anodizing fixture for aluminum profiles with good stability. Background Technology
[0002] The anodizing process of aluminum profiles uses an electrochemical oxidation method. The aluminum profile is placed in a sulfuric acid solution to form a conductive circuit system. Oxygen is generated at the cathode and at the anode, and combines with the surface of the aluminum profile to form a dense aluminum oxide film, thereby improving the protective, decorative, insulating and corrosion resistant properties of the aluminum profile surface.
[0003] The utility model with authorization announcement number CN216129698U provides a stable aluminum profile anodizing fixture. Through the combination of the fixture mechanism and multiple fixing mechanisms, aluminum profiles of different lengths can be effectively fixed, improving stability and preventing the aluminum profiles from shaking or falling during the anodizing process, thus improving the performance.
[0004] However, when the hanger provided by the aforementioned patent clamps and fixes shorter aluminum profiles, the second fixing rod needs to be close to the center of the fixing plate. Therefore, after the operator fixes the shorter aluminum profile on the hanger, the center of gravity of the hanger will be on one side of the hook axis. After the operator suspends the hanger inside the anodizing equipment through the hook, the hanger and the aluminum profile fixed on the hanger will tilt to one side. When the anodizing equipment performs anodizing treatment on the tilted aluminum profile, due to gravity, the tilted aluminum profile will cause uneven flow of electrolyte on the surface of the aluminum profile, resulting in uneven oxide film formation speed and thickness. Therefore, the oxide film quality on the surface of the aluminum profile will be poor, with some areas having no oxide film or thin and incomplete film layers. Utility Model Content
[0005] The purpose of this invention is to provide a stable aluminum profile anodizing fixture to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, one of the objectives of this utility model is to provide a stable aluminum profile anodizing fixture, including a top plate. T-shaped grooves are provided at both ends of the bottom of the top plate. A T-shaped slider is slidably disposed inside the T-shaped groove. A vertical rod is fixedly connected to the lower side of the T-shaped slider. Several clamping mechanisms are symmetrically and vertically arrayed and fixedly connected to the sides of two vertical rods that are close to each other. Two clamping mechanisms at the same height are used to clamp and fix the same aluminum profile. A displacement mechanism is provided on the top plate to drive the two vertical rods to move relative to each other. A hook assembly is provided on the upper side of the displacement mechanism.
[0007] As a further improvement to this technical solution, racks are fixedly connected to the sides of the two vertical rods that are close to each other. The connection between the racks and the vertical rods is located near the top of the vertical rods. The displacement mechanism includes a main shaft that is rotatably set at the center of the top plate. The lower end of the main shaft extends to the lower side of the top plate and is coaxially fixedly connected to a gear. The two racks mesh with the two sides of the gear respectively.
[0008] As a further improvement to this technical solution, the displacement mechanism also includes a worm gear coaxially fixed on the main shaft. The worm gear is disposed on the upper side of the top plate, and a worm is rotatably disposed on the upper side of the top plate. The worm meshes with the worm gear, and both ends of the worm are coaxially fixedly connected to knobs.
[0009] As a further improvement to this technical solution, the hook assembly includes a rotating sleeve rotatably mounted on the upper end of the main shaft. A hook is fixedly connected to the upper side of the rotating sleeve, and an extension plate is fixedly connected to one side of the rotating sleeve. A limit rod is fixedly connected to the upper side of the top plate, and the upper end of the limit rod passes through the extension plate and extends outward.
[0010] As a further improvement to this technical solution, guide grooves are provided on both racks, and positioning blocks are slidably arranged inside the guide grooves. The upper end of the positioning blocks is fixedly arranged on the lower side of the top plate.
[0011] As a further improvement to this technical solution, the clamping mechanism includes a mounting frame fixedly connected to the side wall of the vertical rod. Two bottom columns are symmetrically fixedly connected to the bottom surface inside the mounting frame. A movable plate is provided at the upper end of the mounting frame. Two top columns are symmetrically fixedly connected to the lower side of the movable plate. The lower end of the top column passes through the upper side wall of the mounting frame and extends into the interior of the mounting frame. The two top columns are respectively located directly above the two bottom columns, and the ends of the top columns and bottom columns that are close to each other are both set as ball heads.
[0012] As a further improvement to this technical solution, the clamping mechanism also includes a threaded rod rotatably disposed on the side of the mounting bracket, the threaded rod being threadedly connected to the movable plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This stable aluminum profile anodizing fixture utilizes a worm gear to drive a worm wheel, main shaft, and gears. This causes two racks to move two vertical rods relative to each other, allowing the operator to adjust the spacing between the two clamping mechanisms at the same height according to the length of the aluminum profile. This ensures that the two clamping mechanisms at the same height can clamp and fix the ends of aluminum profiles of different lengths. Simultaneously, the distance between the two vertical rods and the main shaft remains constant, ensuring that the fixture's center of gravity is located on the axis of the main shaft and the hook. Therefore, after suspending the fixture inside the anodizing equipment via the hook, the fixture and the several aluminum profiles fixed to it remain horizontal, preventing uneven oxide film formation during anodizing and thus improving the quality of the anodizing process.

[0027] 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.
[0028] Example 1
[0029] Please see Figures 1-5 As shown, one of the objectives of this embodiment is to provide a stable aluminum profile anodizing fixture, including a top plate 1. T-shaped grooves 11 are provided at both ends of the bottom of the top plate 1. T-shaped sliders 21 are slidably disposed inside the T-shaped grooves 11. Vertical rods 2 are fixedly connected to the lower side of the T-shaped sliders 21. The T-shaped grooves 11 and T-shaped sliders 21 cooperate to restrict the separation of the vertical rods 2 from the top plate 1. Several clamping mechanisms 5 are symmetrically and vertically arrayed and fixedly connected to the sides of the two vertical rods 2 that are close to each other. Two clamping mechanisms 5 located at the same height are used to clamp and fix the same aluminum profile, keeping the aluminum profile fixed on this fixture in a horizontal state and improving the quality of the aluminum profile anodizing treatment. The structure of the clamping mechanism 5 is detailed below, referring to... Figure 5The clamping mechanism 5 includes a mounting bracket 51 fixedly connected to the side wall of the vertical rod 2. The mounting bracket 51 is a C-shaped structure with an opening on one side, and the opening of the mounting bracket 51 is close to the center of the top plate 1. Two bottom posts 52 are symmetrically fixedly connected to the bottom surface inside the mounting bracket 51. At the same time, a movable plate 53 is provided at the upper end of the mounting bracket 51. Two top posts 54 are symmetrically fixedly connected to the lower side of the movable plate 53. The top posts 54 are vertically arranged, and the lower end of the top posts 54 penetrates through the upper side wall of the mounting bracket 51 and extends into the mounting bracket 51. The two top posts 54 are respectively located directly above the two bottom posts 52, and the ends of the top posts 54 and the bottom posts 52 that are close to each other are all set as ball heads. The ball heads can reduce the contact area between the top posts 54, the bottom posts 52 and the aluminum profile, so that the aluminum profile can form an oxide film more fully on the surface during anodizing, thereby improving the quality of the anodizing treatment of the aluminum profile. The clamping mechanism 5 also includes a rotatable part set on the upper side of the mounting bracket 51. The threaded rod 55 is threadedly connected to the movable plate 53. The operator inserts both ends of the aluminum profile into the two mounting brackets 51 at the same height, and positions the two top posts 54 inside the mounting brackets 51 on the upper side of the aluminum profile and the two bottom posts 52 inside the mounting brackets 51 on the lower side of the aluminum profile. The operator then screws the threaded rod 55 on the two mounting brackets 51 one after the other. Through the threaded connection between the threaded rod 55 and the movable plate 53, the movable plate 53 moves the two top posts 54 closer to the two bottom posts 52 until the top posts 54 and bottom posts 52 contact the upper and lower sides of the aluminum profile, respectively. The aluminum profile is then clamped and fixed on the fixture. After fixing several aluminum profiles in a vertical array on the fixture in this way, the fixture is suspended in the anodizing equipment. After immersing several aluminum profiles in the electrolyte in the anodizing equipment, the several horizontally positioned aluminum profiles can be anodized.
[0030] When anodizing aluminum profiles of different lengths, there is a problem that the two ends of the aluminum profile cannot be simultaneously inserted into the two mounting brackets 51 located at the same height, resulting in the aluminum profile being unable to be stably clamped and fixed on the fixture. To solve this problem, a displacement mechanism 4 is provided on the top plate 1. The displacement mechanism 4 is used to drive the two vertical rods 2 to move relative to each other. The structure of the displacement mechanism 4 is detailed below, referring to... Figure 2 , Figure 3 and Figure 4A rack 3 is fixedly connected to each of the two vertical rods 2 on their sides, with the connection point between the rack 3 and the vertical rod 2 located near the top of the vertical rod 2. Guide grooves 31 are provided on both racks 3, and positioning blocks 12 are slidably disposed inside the guide grooves 31. The upper end of the positioning blocks 12 is fixedly disposed on the lower side of the top plate 1. The displacement mechanism 4 includes a main shaft 41 rotatably disposed at the center of the top plate 1. The lower end of the main shaft 41 extends to the lower side of the top plate 1 and is coaxially fixedly connected to a gear 44. The two racks 3 mesh with the two sides of the gear 44 respectively. The positioning blocks 12 and the guide grooves 31 cooperate to restrict the racks 3 to move only along the axis of the racks 3, thereby ensuring stable meshing between the racks 3 and the gear 44. The displacement mechanism 4 also includes a worm gear 42 coaxially fixed on the main shaft 41. The worm gear 42 is disposed on the upper side of the top plate 1, and a worm 43 is rotatably disposed on the upper side of the top plate 1. The worm 43 meshes with the worm gear 42. Each end is coaxially fixed with a knob. The operator rotates one of the knobs to drive the worm 43 to rotate. Through the meshing transmission between the worm 43 and the worm wheel 42, the worm wheel 42 drives the main shaft 41 and the gear 44 to rotate. Through the meshing transmission between the gear 44 and the two racks 3, the two racks 3 drive the two vertical rods 2 to move relative to each other along the axis of the T-shaped slide groove 11. At the same time, the self-locking transmission of the worm 43 and the worm wheel 42 restricts the position change of the vertical rods 2 when the worm 43 is not rotated. This allows the operator to adjust the distance between the two vertical rods 2 according to the length of the aluminum profile, and thus adjust the distance between the two clamping mechanisms 5 at the same height. This allows the operator to fix the two ends of aluminum profiles of different lengths in the two clamping mechanisms 5 at the same height. This allows the fixture to stably fix aluminum profiles of different lengths, and then cooperate with the anodizing equipment to perform anodizing treatment on aluminum profiles of different lengths.
[0031] Meanwhile, a hook assembly 6 is provided on the upper side of the displacement mechanism 4. The hook assembly 6 is used to suspend the fixture inside the anodizing equipment. The structure of the hook assembly 6 is described in detail below, referring to... Figure 3The hook assembly 6 includes a rotating sleeve 61 rotatably mounted on the upper end of the main shaft 41. A hook 62 is fixedly connected to the upper side of the rotating sleeve 61, and an extension plate 63 is fixedly connected to one side of the rotating sleeve 61. A limit rod 13 is fixedly connected to the upper side of the top plate 1. The upper end of the limit rod 13 passes through the extension plate 63 and extends outward. The limit rod 13 and the extension plate 63 cooperate to restrict the rotation of the rotating sleeve 61, so that when the main shaft 41 rotates, the rotating sleeve 61 will not rotate with the main shaft 41, thereby fixing the position of the hook 62. The operator can hook the hook 62 onto the hook groove or hook ring reserved inside the anodizing equipment to hang the hook. The fixture is suspended inside the anodizing equipment. The connection between the hook 62 and the rotating sleeve 61 is coaxially set with the rotating sleeve 61 and the main shaft 41. At the same time, no matter where the two vertical rods 2 are moved to under the top plate 1, the distance between the two vertical rods 2 and the main shaft 41 is the same. The center of gravity of the fixture is always located on the axis of the main shaft 41. Therefore, after the fixture is suspended inside the anodizing equipment by the hook 62, the fixture and several aluminum profiles fixed on it can be kept in a horizontal state, avoiding uneven oxide film formation on the surface of the aluminum profiles during anodizing treatment, thereby improving the quality of anodizing treatment of aluminum profiles.
