Description

Technical Field

[0001] The utility model relates to the technical field of anodizing production, in particular to a tooling hanger for anodizing aluminum alloys. Background Art

[0002] Anodizing is the electrochemical oxidation of metals or alloys. Aluminum and its alloys form an oxide film on the aluminum product (anode) under the action of an applied current in a corresponding electrolyte and specific process conditions. Unless otherwise specified, anodizing usually refers to sulfuric acid anodizing.

[0003] Currently, the hooks and connecting rods of some existing aluminum alloy anodizing tooling are usually formed in one piece. Therefore, when the hooks are worn or deformed and need to be replaced, the connecting rods can only be disassembled from the bottom of the lifting platform for replacement. The inconvenience of replacement also leads to a relatively low utilization rate of the connecting rods and is relatively inconvenient to use. For this reason, we propose a tooling sling for aluminum alloy anodizing to solve or improve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a tooling hanger for anodizing aluminum alloys, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: it includes a connecting rod, a cylinder arranged on one side of the bottom of the connecting rod, a fixed block fixed to the inner surface of the cylinder, an inverted L-shaped slide groove opened on the surface of the connecting rod close to the bottom side, a first placement groove opened on the surface of the connecting rod, the first placement groove is located at the bottom of the inverted L-shaped slide groove, a second placement groove opened on the surface of the connecting rod, the second placement groove is located at the top of the inverted L-shaped slide groove, a ring is sleeved on the surface of the connecting rod, and a limit plate is fixed to the bottom of the ring.

[0006] Furthermore, a cavity is provided inside the connecting rod, and a spring is fixed inside the cavity.

[0007] Furthermore, the connecting plate is fixed to the bottom of the spring, and the interior and surface of the connecting rod are provided with slots for the connecting plate to move.

[0008] Furthermore, a hook is fixed to the bottom of the cylinder, and two groups of fixing blocks are symmetrically fixed on the inner surface of the cylinder.

[0009] Furthermore, the limiting plate is located inside the inverted L-shaped sliding groove and the limiting plate can be inserted into the second placement groove.

[0010] Furthermore, two groups of inverted L-shaped sliding grooves, second placement grooves and first placement grooves are symmetrically opened on the surface of the connecting rod, and the number of the limiting plates is the same as the number of the second placement grooves.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by providing a cylinder, when the hook is worn and deformed and needs to be replaced, the cylinder can be directly removed from the bottom side of the connecting rod, so that the hook can be replaced alone without disassembling and replacing the connecting rod. The replacement is relatively convenient and the utilization rate of the connecting rod is improved, making it relatively convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5, including a connecting rod 1, a cylinder 2 arranged on one side of the bottom of the connecting rod 1, the connecting rod 1 can be inserted into the interior of the cylinder 2, a hook 3 is fixed to the bottom of the cylinder 2, and a fixed block 6 is fixed to the inner surface of the cylinder 2, and two groups of fixed blocks 6 are symmetrically fixed on the inner surface of the cylinder 2, an inverted L-shaped groove 5 is opened on the surface of the connecting rod 1 close to the bottom side, the fixed block 6 can be inserted into the interior of the inverted L-shaped groove 5, a first placement groove 7 is opened on the surface of the connecting rod 1, the first placement groove 7 is located at the bottom of the inverted L-shaped groove 5, the first placement groove 7 is connected to the interior of the inverted L-shaped groove 5 and the space opened by the first placement groove 7 is slightly larger than the fixed block 6, the fixed block 6 can be moved to the interior of the first placement groove 7 through the inverted L-shaped groove 5, and the second placement groove 9 is opened on the surface of the connecting rod 1, and the second placement groove 9 is located at the inverted L-shaped groove 5 At the top, the second placement slot 9 is connected to the internal space of the inverted L-shaped slide 5. The inverted L-shaped slide 5, the second placement slot 9 and the first placement slot 7 are symmetrically opened in two groups on the surface of the connecting rod 1. The ring 4 is sleeved on the surface of the connecting rod 1, and the limit plate 8 is fixed to the bottom of the ring 4. When the ring 4 moves, it will drive the fixed limit plate 8 to move. The number of limit plates 8 is the same as the number of the second placement slot 9. The limit plate 8 is located inside the inverted L-shaped slide 5 and the limit plate 8 can be inserted into the second placement slot 9. A cavity is provided inside the connecting rod 1, and a spring 10 is fixed inside the cavity. The connecting plate 11 is fixed to the bottom of the spring 10. The interior and surface of the connecting rod 1 are provided with slots for the connecting plate 11 to move. The two ends of the connecting plate 11 slightly protrude from the surface of the connecting rod 1 and are fixedly connected to the ring 4.

[0020] When the collar 4 moves, it will drive the fixed connecting plate 11 to move. When the connecting plate 11 moves, it will squeeze the spring 10 to deform the spring 10. When there is no external force interference, the spring 10 will push the connecting plate 11 to move. When the cylinder 2 is sleeved on the bottom of the connecting rod 1 so that the connecting rod 1 is inserted into the cylinder 2, the fixed block 6 can be inserted into the inside of the inverted L-shaped slide 5 and moved to the top side of the inverted L-shaped slide 5. At this time, the collar 4 is moved so that the collar 4 drives the limit plate 8 to move, so that the limit plate 8 can be moved to the inside of the second placement groove 9, so that the fixed block 6 can be rotated a certain angle when it is located at the top of the inverted L-shaped slide 5, so that the fixed block 6 can move When the spring 10 is in contact with the top of the fixing block 6, the fixing block 6 is pushed to the inside of the first placement groove 7. The spring 10 will apply a certain pressure to the limiting plate 8 through the connecting plate 11 and the collar 4, so that the limiting plate 8 can limit the position of the fixing block 6 to a certain extent, reduce or avoid the fixing block 6 from detaching from the inside of the first placement groove 7, and thus the cylinder 2 and the hook 3 are installed at the bottom of the connecting rod 1.

[0021] Working principle: when it is necessary to perform an anodizing process on the aluminum alloy, the anodizing operation can be performed by hanging the aluminum alloy workpiece on the surface of the hook 3 and immersing the hook 3 and the workpiece in the anodizing tank. After completion, the hook 3 and the aluminum alloy workpiece after anodizing are taken out of the anodizing tank together and the workpiece is removed from the surface of the hook 3. When the hook 3 is worn or deformed due to use and needs to be replaced, the ring 4 is pushed to drive the limit plate 8 to move, so that the limit plate 8 moves to the inside of the second placement groove 9. At this time, the limit plate 8 no longer restricts the position of the fixed block 6. By pushing the cylinder 2 to move, the cylinder 2 drives the fixed block 6 to move, so that the fixed block 6 can be moved out from the inside of the first placement groove 7. At this time, the cylinder 2 is rotated so that the cylinder 2 drives the fixed block 6 to rotate to the top side of the inverted L-shaped slide groove 5 and the cylinder 2 is moved downward to remove the cylinder 2 and the hook 3 from the bottom side of the connecting rod 1, thereby realizing the replacement of the hook 3 alone, without the need to disassemble and replace the connecting rod 1. The replacement is relatively convenient while improving the utilization rate of the connecting rod 1, and it is relatively convenient to use.

[0022] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
