Description

Technical Field

[0001] This utility model relates to an anodizing hanger, specifically, to a multi-point positioning anodizing dyeing hanger. Background Technology

[0002] The process of using aluminum or aluminum alloy products as the anode and placing them in an electrolyte solution for electrolysis to form an aluminum oxide film on their surface is called anodizing of aluminum and aluminum alloys. The aluminum oxide film can be dyed to present various bright colors, increasing the decorative effect of metal products. At the same time, the aluminum oxide film can effectively resist the erosion of the atmosphere, water and other corrosive substances, extending the service life of metal products.

[0003] The utility model with authorization announcement number CN219470256U provides a hanger for anodizing aluminum alloy sheets. By setting several steel wires on the crossbar, the weight of the aluminum alloy is effectively distributed, making the support more stable. At the same time, the steel wires can also prevent the bottom surface of the aluminum alloy from being excessively affected during oxidation.

[0004] However, in the existing technology, in order to improve the quality and effect of aluminum alloy sheets in the cleaning and dyeing process and ensure that the surface treatment of aluminum alloy sheets is uniform and achieves the expected oxidation effect, it is usually necessary to move the aluminum alloy sheet in the anodizing equipment by the hanger. In the above-mentioned patent, after the aluminum alloy sheet is placed on the upper surface of the crossbar, if the opposite sides of the aluminum alloy sheet cannot be tightly attached to the two sets of steel wires located on both sides of the crossbar, the aluminum alloy sheet is prone to displacement on the upper side of the crossbar when the position of the hanger changes in the anodizing equipment. The moving aluminum alloy sheet will collide with the steel wires, and the dyed alumina film on the aluminum alloy sheet will be damaged due to the collision, resulting in the white lines of the aluminum alloy sheet being exposed, thus affecting the dyeing effect of the aluminum alloy sheet. Utility Model Content

[0005] The purpose of this invention is to provide a multi-point positioning anodizing dyeing 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 multi-point positioning anodizing dyeing fixture, including a base frame. An n-shaped upright is fixedly connected to the center of the upper surface of the base frame. Two hooks are symmetrically fixedly connected to the upper surface of the upright. Several partition frames are fixedly connected in a vertical array inside the upright. Several rotating plates are rotatably connected in a horizontal array inside the partition frames. One end of each rotating plate extends to the outside of the partition frame and is fixedly connected to a limiting rod. The limiting rod and the rotating plate form an L-shaped structure. A half-gear is fixedly connected at the connection between the rotating plate and the partition frame. A double-sided rack is slidably arranged inside the partition frame. Several half-gears inside the partition frame mesh with both sides of the double-sided rack. A displacement mechanism is arranged near one end of the partition frame. The displacement mechanism is used to drive the double-sided rack to move along the axial direction of the double-sided rack.

[0007] As a further improvement to this technical solution, a movable groove is provided at one end of the top of the partition frame, and a movable block is slidably disposed in the movable groove. The lower end of the movable block is fixedly disposed on the top of the double-sided rack.

[0008] As a further improvement to this technical solution, the displacement mechanism includes a threaded rod rotatably mounted on the inner side wall of the frame. The axis of the threaded rod is parallel to the axis of the double-sided rack, and a knob is coaxially fixedly connected to the other end of the threaded rod. The moving block is threadedly connected to the threaded rod.

[0009] As a further improvement to this technical solution, the top and bottom of the partition frame are provided with a number of holes arranged in a horizontal array. The axis of the holes is located between two adjacent half gears, and the diameter of the holes is greater than the width of the double-sided rack.

[0010] As a further improvement to this technical solution, several limiting rods on the same partition frame are symmetrically distributed with the double-sided rack axis as the axis of symmetry. When the rotating plate drives the limiting rods to rotate, the two limiting rods symmetrically arranged on both sides of the partition frame move closer to each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This multi-point positioning anodizing dyeing fixture, after placing the aluminum alloy sheet on the upper surface of the partition frame, moves the double-sided rack to make the rotating plate drive the limiting rods to rotate. This causes several limiting rods on the same partition frame to clamp and fix the aluminum alloy sheet placed on the upper surface of the partition frame, thereby limiting the change of position of the aluminum alloy sheet on the upper surface of the partition frame and preventing damage to the surface dyeing oxide film caused by collision between the aluminum alloy sheet and the limiting rods, thus ensuring the dyeing effect of the aluminum alloy sheet.

[0026] 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.

[0027] Example 1

[0028] Please see Figure 1 and Figure 2As shown, one of the objectives of this embodiment is to provide a multi-point positioning anodizing dyeing fixture, including a base frame 1, which is a square frame composed of four square tubes. An n-shaped upright frame 2 is fixedly connected to the center of the upper surface of the base frame 1. The upright frame 2 is an n-shaped frame composed of three square tubes. Two hooks 11 are symmetrically fixedly connected to the upper surface of the upright frame 2. The fixture is suspended in the anodizing equipment via the two hooks 11. Several partition frames 3 are fixedly connected in a vertical array inside the upright frame 2, and several horizontally arranged rotatable partition frames 3 are connected to the partition frames 3. The rotating plate 4 extends to the outside of the partition frame 3 and is fixedly connected to the limiting rod 41. The limiting rod 41 and the rotating plate 4 form an L-shaped structure. The limiting rod 41 is fixed on the upper side of the rotating plate 4, and the upper end of the limiting rod 41 is higher than the upper surface of the partition frame 3. After the worker places the aluminum alloy sheet on the upper surface of the partition frame 3, the two sides of the aluminum alloy sheet are located on the upper side of the rotating plate 4. The limiting rod 41, together with the upright frame 2, restricts the horizontal movement range of the aluminum alloy sheet, thereby preventing the aluminum alloy sheet from falling off the partition frame 3 and improving the stability of the partition frame 3 when placing the aluminum alloy sheet.

[0029] After placing the aluminum alloy sheet on the upper surface of the partition frame 3, if the opposite sides of the aluminum alloy sheet cannot be tightly attached to the two sets of limiting rods 41 located on both sides of the partition frame 3, the aluminum alloy sheet is prone to displacement on the upper side of the partition frame 3 when the position of the hanger changes in the anodizing equipment. The moving aluminum alloy sheet will collide with the limiting rods 41, resulting in damage to the dyed oxide film on the surface of the aluminum alloy sheet due to the collision. To solve this problem, refer to... Figure 3 and Figure 4A half-gear 42 is fixedly connected at the connection between the rotating plate 4 and the partition frame 3. The central axis of the half-gear 42 is on the same straight line as the axis of hinge between the rotating plate 4 and the partition frame 3. A double-sided rack 5 is slidably arranged inside the partition frame 3. Several half-gears 42 inside the partition frame 3 mesh with both sides of the double-sided rack 5. A displacement mechanism 6 is located near one end of the partition frame 3. The displacement mechanism 6 drives the double-sided rack 5 to move along its axial direction. When the displacement mechanism 6 drives the double-sided rack 5 to move, the meshing transmission between the half-gears 42 and the double-sided rack 5 causes the half-gears 42 to drive the corresponding rotating plate 4 to rotate. The rotating plate 4 then drives the corresponding limiting rod 41 to rotate. Several limiting rods 41 on the same partition frame 3 are symmetrically distributed around the axis of the double-sided rack 5. When the rotating plate 4 drives the limiting rods 41 to rotate, the two limiting rods 41 symmetrically arranged on both sides of the partition frame 3 approach each other. When the two symmetrically distributed limiting rods 41 contact the opposite sides of the aluminum alloy plate, the several limiting rods 41 on the same partition frame 3 clamp and fix the aluminum alloy plate placed on the upper surface of the partition frame 3. This restricts the change of position of the aluminum alloy plate on the upper surface of the partition frame 3, avoids damage to the surface dyeing oxide film of the aluminum alloy plate due to the interaction between the aluminum alloy plate and the limiting rods 41, ensures the dyeing effect of the aluminum alloy plate, and guarantees the aesthetics and yield of the aluminum alloy plate.

[0030] The structure of displacement mechanism 6 is detailed below, referring to... Figure 5 A movable groove 32 is provided at one end of the top of the partition frame 3. The axis of the movable groove 32 is on the same vertical plane as the axis of the double-sided rack 5. A movable block 51 is slidably disposed in the movable groove 32. The lower end of the movable block 51 is fixedly disposed on the top of the double-sided rack 5. The displacement mechanism 6 includes a threaded rod 61 rotatably disposed on the inner wall of the upright frame 2. The axis of the threaded rod 61 is parallel to the axis of the double-sided rack 5, and the other end of the threaded rod 61 is coaxially fixedly connected to a knob 62. The movable block 51 is threadedly connected to the threaded rod 61. When the worker holds the knob 62 and turns the threaded rod 61, the movable block 51 moves horizontally along the axis of the threaded rod 61 through the threaded connection between the threaded rod 61 and the movable block 51. The moving movable block 51 drives the double-sided rack 5 to move synchronously with the movable block 51 inside the partition frame 3. Figure 6 When the moving block 51 moves the double-sided rack 5 away from the center of the partition frame 3, the double-sided rack 5 drives several rotating plates 4 and several limiting rods 41 to rotate synchronously, so that the distance between the two limiting rods 41 symmetrically arranged on both sides of the partition frame 3 is reduced, thereby restricting the change of position of the aluminum alloy plate on the upper surface of the partition frame 3 and avoiding damage to the surface oxide film of the aluminum alloy plate due to collision with the limiting rods 41.

[0031] To increase the contact area between the aluminum alloy sheet and the electrolyte solution, and to improve the anodizing effect of the anodizing equipment on the aluminum alloy sheet, several perforations 31 are horizontally arrayed at the top and bottom of the partition frame 3. The axis of the perforation 31 is located between two adjacent half gears 42, and the diameter of the perforation 31 is larger than the width of the double-sided rack 5. After the worker places several aluminum alloy sheets on the upper surface of several partition frames 3, the worker immerses this fixture in the electrolyte solution in the anodizing equipment. The electrolyte solution can contact the lower side of the aluminum alloy sheet through the perforations 31, thereby improving the anodizing effect of the anodizing equipment on the aluminum alloy sheet.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
