Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy cylindrical parts processing technology, and in particular to an anodizing device for aluminum alloy cylindrical parts. Background Technology

[0002] Anodizing of aluminum alloy cylindrical parts refers to the process of forming an oxide film on the surface of aluminum alloy cylindrical parts. This oxide film has protective, decorative, and functional properties, preventing further oxidation of the aluminum alloy and enhancing its corrosion resistance and wear resistance.

[0003] CN217026108U discloses an oxidation tank and apparatus for anodizing aluminum alloy cylindrical parts. By immersing the aluminum alloy cylindrical part to be anodized upside down in the electrolyte of the oxidation tank body, after anodizing is completed, the aluminum alloy cylindrical part to be anodized can be lifted directly by a simple lifting operation. The electrolyte inside the aluminum alloy cylindrical part to be anodized flows out directly from the bottom opening of the aluminum alloy cylindrical part under the action of gravity, without the need for secondary operation, which facilitates subsequent processes. Moreover, the setting of a negative pressure generating mechanism and an exhaust pipe can expel the air inside the aluminum alloy cylindrical part to be anodized immersed in the electrolyte, so that the electrolyte of the oxidation tank body can enter from the bottom opening of the aluminum alloy cylindrical part to be anodized and fill the interior of the aluminum alloy cylindrical part to be anodized, thereby ensuring the uniformity of anodizing inside the aluminum alloy cylindrical part.

[0004] The anodizing tank and apparatus used for anodizing aluminum alloy cylinders allow the electrolyte inside the cylinder to flow out directly from the bottom opening of the cylinder under gravity after the anodizing process is completed. However, residual electrolyte will remain on the inner wall of the cylinder, causing leakage during subsequent processing or handling, which will pollute the working environment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anodizing device for aluminum alloy cylindrical parts.

[0006] This utility model is achieved using the following technical solution: an anodizing device for aluminum alloy cylindrical parts, comprising an oxidation tank, a fixed frame fixedly connected to the top of the oxidation tank, a heat pump fixedly connected to the left end of the oxidation tank, an air outlet pipe connected to the output end of the heat pump, a movable component provided at the top of the oxidation tank, an electric telescopic rod provided at the lower end of the movable component, a hanger fixedly connected to the output end of the electric telescopic rod, an aluminum alloy cylindrical part provided inside the hanger, a fixed component provided at the upper end of the aluminum alloy cylindrical part, a negative pressure pump fixedly connected to the bottom of the oxidation tank, and an air extraction pipe connected to the top of the negative pressure pump.

[0007] Through the above technical solution, the heat pump delivers hot air to the inner wall of the aluminum alloy cylinder through the air outlet pipe, drying the residual electrolyte on the inner wall of the aluminum alloy cylinder and avoiding dripping when it is removed later, thereby avoiding environmental impact and improving practicality.

[0008] As a further improvement to the above solution, the moving component includes a motor, the output end of which is fixedly connected to a lead screw, and the surface of the lead screw is threadedly connected to a mounting base.

[0009] The above technical solution uses a motor to drive a lead screw to rotate, causing the mounting base to move to one side, thereby moving the position of the hanger and adjusting the position of the aluminum alloy cylinder.

[0010] As a further improvement to the above solution, the right end of the motor is fixedly connected to the left end of the fixing frame, both ends of the lead screw are rotatably connected to the inner wall of the fixing frame, a limiting groove is opened on the top of the fixing frame, and the top of the mounting base is slidably connected to the inner wall of the limiting groove.

[0011] The above technical solution limits the upper end of the mounting base by using a limiting groove, preventing the mounting base from rotating with the lead screw, thus enabling the mounting base to move left and right.

[0012] As a further improvement to the above solution, the bottom of the mounting base is fixedly connected to the top of the electric telescopic rod, and there are two electric telescopic rods, which are symmetrically distributed with the mounting base as the center.

[0013] The above technical solution uses an electric telescopic rod to push the hanger downwards, allowing the aluminum alloy cylinder to enter the oxidation tank for electrolysis.

[0014] As a further improvement to the above solution, the end of the air outlet pipe away from the heat pump extends into the interior of the oxidation tank, and the upper end of the exhaust pipe extends into the interior of the oxidation tank. Both the upper ends of the air outlet pipe and the exhaust pipe are provided with several through holes.

[0015] The above technical solution facilitates airflow through the air outlet pipe and air extraction pipe by using through holes in the air outlet pipe and air extraction pipe.

[0016] As a further improvement to the above solution, the fixing component includes an extension rod, an extension plate is fixedly connected to the top of the extension rod, a threaded rod is threadedly connected to the inner wall of the extension plate, and the lower end of the threaded rod passes through the extension plate and is rotatably connected to a pressing plate.

[0017] The above technical solution utilizes a rotating threaded rod to push the extrusion plate downwards, thereby pressing and fixing the aluminum alloy cylinder and ensuring stability during the anodizing process.

[0018] As a further improvement to the above solution, the bottom of the extension rod is rotatably connected to the inner wall of the hanger, and the bottom of the extrusion plate is in contact with the top of the aluminum alloy cylinder.

[0019] The above technical solution allows the extension plate to rotate via the extension rod, thereby adjusting the position of the extrusion plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model incorporates a heat pump, an air outlet duct, a moving component, an electric push rod, and a hanging device. Specifically, a motor drives a lead screw to rotate, causing the mounting base to slide to the left, moving the aluminum alloy cylinder. When it reaches the upper end of the air outlet duct, an electric telescopic rod pushes the hanging device downwards, allowing the air outlet duct to enter the interior of the aluminum alloy cylinder. The heat pump then activates, delivering hot air through the air outlet duct to the inner wall of the aluminum alloy cylinder to dry any residual electrolyte. This prevents electrolyte leakage during subsequent removal, thus improving the working environment and enhancing practicality.

[0022] This invention uses a fixing component, specifically by rotating an extension plate to rotate an extrusion plate to the upper end of an aluminum alloy cylinder, and rotating a threaded rod to push the extrusion plate downwards. The extrusion plate presses and fixes the aluminum alloy cylinder, ensuring stability during the anodizing process. Attached Figure Description
