Description

Technical Field

[0001] The present application relates to the field of aluminum cover processing, and in particular to an aluminum cover oxidation device. Background Art

[0002] Aluminum and its alloys are one of the most widely used, economical and practical materials at present, and are widely used in the production of various products; aluminum caps are often used in bottle caps of cosmetics, medical supplies, etc.

[0003] During the production process, the aluminum cover will be treated with a coarse sand surface treatment method. The steps are to degrease, alkaline wash, neutralize, acid etch, neutralize, alkaline etch, neutralize, anodize and seal the aluminum alloy workpiece in sequence. The anodizing step requires the use of an aluminum cover oxidation device.

[0004] Currently, a Chinese utility model application, publication number CN211227388U, discloses an aluminum cover oxidation device comprising a mounting frame and multiple brackets mounted on the mounting frame. The brackets are provided with multiple elastic expansion tabs for clamping the aluminum cover. The mounting frame is rotatably connected to multiple rotating shafts, which pass through the multiple elastic expansion tabs and, at one end, protrude from the mounting frame and are connected to worm gears. The mounting frame is rotatably connected to a worm that meshes with the multiple worm gears. A tensioning member is provided between the rotating shaft and the elastic expansion tabs to tighten the device as it rotates. This utility model provides a quick clamping effect.

[0005] The elastic support piece is supported on the inner side wall of the aluminum cover. Due to the low hardness of the aluminum cover, during the clamping process, the inner side wall of the aluminum cover is only subjected to the clamping force in opposite directions at both ends of the elastic support piece. The aluminum cover is subjected to uneven force in the circumferential direction, which can easily cause the aluminum cover to deform, resulting in poor quality of the aluminum cover. Utility Model Content

[0006] In order to reduce deformation of the aluminum cover during the clamping process, the present application provides an aluminum cover oxidation device.

[0007] This application provides an aluminum cover oxidation device, which adopts the following technical solution:

[0008] An aluminum cover oxidation device includes a frame and several clamping components for clamping the aluminum cover, the clamping components are all distributed on the frame, the clamping components include a cylinder, a deformable ring cover, a sealing plate and a driving member, the cylinder is arranged on the frame, a cavity is opened inside the cylinder, a connecting hole connected to the cavity is opened on the side wall of the cylinder, the sealing plate is located in the cavity and abuts against the inner side wall of the cavity, the connecting hole is always located on one side of the sealing plate, the driving member is used to drive the sealing plate to move, the deformable ring cover is sleeved on the cylinder, and the deformable ring cover covers the connecting hole.

[0009] By adopting the above technical solution, the aluminum cover is placed on the cylinder until the deformable ring cover is located inside the aluminum cover, and then the driving member is started, which drives the sealing plate to move, and the sealing plate moves toward the direction of the communicating hole. The side of the cylinder where the communicating hole is opened is squeezed, and the gas enters the deformable ring cover through the communicating hole. After the deformable ring cover is inflated, it abuts against the inner wall of the aluminum cover. The deformable ring cover abuts against the surrounding side of the inner wall of the aluminum cover, so that the inner wall of the aluminum cover is evenly stressed, the deformation of the aluminum cover during the clamping process is reduced, and the oxidation quality of the aluminum cover is improved.

[0010] Optionally, the frame includes an inner frame, an outer frame, several mounting plates and a control member, the inner frame is rotatably connected to the outer frame, the mounting plates are distributed on the inner frame, several clamping components are arranged on the mounting plates, and the driving member is used to drive the inner frame to rotate relative to the outer frame.

[0011] By adopting the above technical solution, during the oxidation process, the frame will generally be immersed in the electrolytic oxidation tank in a vertical state. The aluminum covers located at the highest and lowest points of the frame are inconvenient to pick up and place. The staff can first rotate the inner frame through the operating part, and the inner frame rotates relative to the outer frame until the inner frame is in a horizontal position, so that the aluminum cover can be placed on the clamping assembly on the mounting plate, which is convenient for operation, improves work efficiency and reduces the work intensity of the staff.

[0012] Optionally, the control member includes a worm wheel, a worm and a turntable, the worm wheel is coaxially arranged with the rotation axis of the inner frame, the worm wheel is arranged on the rotation axis of the inner frame, the worm is rotatably connected to the outer frame, the worm wheel is engaged with the worm, and the turntable is arranged on the worm.

[0013] By adopting the above technical solution, when it is necessary to drive the inner frame to rotate relative to the outer frame, the staff rotates the turntable, the turntable drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the inner frame to rotate relative to the outer frame. The worm wheel has self-locking ability. When the turntable is not operated, the inner frame is always kept in a horizontal state, which is convenient for placing the aluminum cover.

[0014] Optionally, the mounting plate is rotatably connected to the inner frame, and the frame is further provided with a retaining member for keeping the cylinder in a vertical state at all times.

[0015] By adopting the above technical solution, the mounting plate can be rotatably connected to the inner frame, and the retaining member ensures that the cylinder on the mounting plate is always in a vertical state, making it convenient for the staff to place the aluminum cover vertically on the cylinder, thereby improving the rationality of the equipment.

[0016] Optionally, the retaining member includes a plurality of retaining gears, a retaining rack and a mating gear, the mating gear is coaxially arranged with the worm, the mating gear is arranged on the inner frame, the length direction of the retaining rack is parallel to the distribution direction of a plurality of mounting plates, the retaining rack is slidably connected to the inner frame along the length direction of the retaining rack, the mating gear is meshed with the retaining rack, a plurality of retaining gears correspond one-to-one to a plurality of mounting plates, the retaining gear is arranged on the rotation axis of the mounting plate, and the retaining gear is meshed with the retaining rack.

[0017] By adopting the above technical solution, when the staff rotates the turntable, the turntable drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the inner frame to rotate relative to the outer frame until the inner frame is in a horizontal state. The rotation of the inner frame will drive the matching gear to rotate, and the matching gear drives the maintaining rack to slide relative to the inner frame. The sliding of the maintaining rack drives the maintaining gear to rotate, and the rotation of the maintaining gear drives the mounting plate to rotate, so that the cylinder on the mounting plate is always in a horizontal state. The inner frame and the mounting plate can be driven to rotate only by the operating member, and the cylinder is always in a horizontal state, which is convenient for staff to operate and control and has a reasonable structure.

[0018] Optionally, the driving member includes a driving plate and a driving column, the length direction of the driving column is parallel to the sealing plate, one end of the driving column is arranged on the sealing plate, and the driving plate is arranged on the other end of the driving column. The side wall of the inner frame is provided with an arc groove, and the driving plate is slidably connected in the arc groove. When the inner frame rotates from a horizontal state to a vertical state, the distance from the driving plate to the rotation axis of the mounting plate gradually decreases.

[0019] By adopting the above technical solution, during the process of the inner frame rotating from a horizontal state to a vertical state, the mounting plate is always in a horizontal state through the retaining member, and the mounting plate will drive the driving plate to move around the rotation axis of the mounting plate. The distance from the driving plate to the rotation axis of the mounting plate gradually decreases, and the driving plate drives the driving column to move, and the driving column drives the sealing plate to move. The sealing plate allows the air pressure in the cylinder to enter the deformable ring cover through the connecting hole, and the deformable ring cover gradually presses against the inner wall of the aluminum cover to achieve a clamping effect. The driving member achieves a linkage effect through the rotation of the mounting plate, further improving the convenience of the equipment.

[0020] Optionally, the cylinder is provided with a guiding slope for facilitating the placement of the aluminum cover.

[0021] By adopting the above technical solution, the guiding slope makes it easier for the staff to place the aluminum cover on the cylinder.

[0022] Optionally, the frame is provided with a hook for facilitating crane lifting.

[0023] By adopting the above technical solution, since the electrolytic oxidation cell is relatively large, a crane or other equipment is conventionally used for lifting, so that the oxidation device can be put into the electrolytic oxidation cell as a whole. The hook also facilitates the lifting operation by the crane.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The sealing sheet changes the internal air pressure of the cylinder to make the deformable ring cover contact the inner wall of the aluminum cover. The aluminum cover is clamped with balanced force, which reduces the deformation of the aluminum cover and increases the electrolyte capacity of the aluminum cover.

[0026] 2. The driving member is used to drive the inner frame to rotate relative to the outer frame. The inner frame in a horizontal state is convenient for workers to take and place the aluminum cover;

[0027] 3. The retaining piece keeps the cylinder on the mounting plate in a horizontal state at all times, thereby improving the stability of the aluminum cover when placed on the cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
