Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a barrel plating device for surface treatment of corrosion-resistant fasteners. Background Technology

[0002] Surface treatment of corrosion-resistant fasteners is a crucial process to ensure their long-term stable operation in various environments. Common surface treatment methods for corrosion-resistant fasteners include electroplating and hot-dip galvanizing. Barrel plating is required for surface treatment of corrosion-resistant fasteners. Barrel plating takes place inside a barrel, which is a container that holds small parts as they are continuously tumbled and plated. A typical barrel is hexagonal prism-shaped and placed horizontally. One side of the barrel wall is open; during barrel plating, the fasteners are loaded into the barrel through the opening, and then the barrel door is closed to seal the opening. By sequentially placing the barrels into different tanks containing treatment solutions (such as cleaning solutions, pickling solutions, zinc solutions, electroplating solutions, etc.), the treatment solution comes into contact with the fasteners through several small holes on the barrel. Driving the barrel to rotate causes the fasteners to tumble inside, ensuring full contact with the treatment solution and achieving surface treatment.

[0003] However, existing barrel plating devices, such as the patent with publication number CN221217960U, disclose a barrel plating tank roller for electroplating. The device places the part to be electroplated into the barrel plating tank body, covers the opening with a cover plate, and rotates the fixing strip on the cover plate so that one end of it is inserted into the fixing opening. Then, the barrel plating tank body is rotated by a motor to achieve barrel plating.

[0004] The above-mentioned device still requires manual operation of the cover plate to open and close the opening, which cannot achieve automated opening and closing. The operation is time-consuming and labor-intensive, and the labor intensity is high. In addition, when the cover plate is open, if the cover plate is in the downward position, the hand is likely to come into contact with the discharged fastener at the moment the opening is opened, which is prone to danger. Utility Model Content

[0005] Therefore, it is necessary to provide a barrel plating apparatus for surface treatment of corrosion-resistant fasteners to address the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides a barrel plating device for surface treatment of corrosion-resistant fasteners, including a mounting frame and a barrel. The barrel has several filter holes, and fixed shafts are fixed at both ends of the barrel. The fixed shafts are coaxially arranged with the barrel and rotatably mounted on the mounting frame. The barrel has an opening, and a cover plate for opening and closing the opening is installed at the opening. A rotating shaft and a rotating sleeve are rotatably mounted on the barrel. The rotating shaft and the rotating sleeve are connected in a transmission connection. The cover plate is fixedly connected to the rotating shaft. The rotating sleeve is coaxially mounted on one of the fixed shafts. A first cylindrical gear is mounted on the rotating sleeve. A power push rod and a self-locking motor are fixedly mounted on the mounting frame. A rack is connected to the output end of the power push rod. The rack is used to mesh with the first cylindrical gear. A second cylindrical gear is mounted on the output end of the self-locking motor. A third cylindrical gear is mounted on one of the fixed shafts and meshes with the second cylindrical gear.

[0007] Preferably, a worm gear is rotatably mounted on the roller, a first bevel gear is fixedly mounted on the worm gear, a second bevel gear that meshes with the first bevel gear is mounted on the rotating sleeve, and a worm wheel that meshes with the worm gear is mounted on the rotating shaft.

[0008] Preferably, a fixing frame is fixed on the roller, and a torsion spring is fitted on the rotating sleeve. One end of the torsion spring is connected to the rotating sleeve, and the other end is connected to the fixing frame.

[0009] Preferably, a guide rail is fixed on the mounting bracket, and the rack is fixedly connected to the slider of the guide rail.

[0010] Preferably, the output end of the power push rod is fixed with a connecting plate, and the connecting plate is fixedly connected to the rack.

[0011] Preferably, the top of the mounting bracket is fixed with a lifting lug.

[0012] Preferably, the roller is fixed with a fixed seat on both sides of the opening, and the rotating shaft is rotatably mounted on the fixed seat.

[0013] Preferably, an extension plate is fixed on the roller, and the worm gear is rotatably mounted on the extension plate via bearings.

[0014] The beneficial effects of this technical solution are as follows: By setting a rotating sleeve that is coaxial with the fixed shaft and connected to the rotating shaft for transmission, the power push rod drives the rack, the first cylindrical gear, and the rotating sleeve to rotate, thereby driving the rotating shaft and the cover plate to move, realizing the function of automatically opening and closing the cover plate, reducing the labor intensity of workers, improving the safety of operation, and improving the efficiency of loading and unloading materials.

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 4This application provides a barrel plating apparatus for surface treatment of corrosion-resistant fasteners, including a mounting frame 1 and a roller 2. The roller 2 has a plurality of filter holes 3. Fixed shafts 4 are fixed at both ends of the roller 2 and are coaxially arranged with the roller 2. The fixed shafts 4 are rotatably mounted on the mounting frame 1. The roller 2 has an opening 5, and a cover plate 6 for opening and closing the opening 5 is installed at the opening 5. The cover plate 6 also has a plurality of filter holes 3. A rotating shaft 7 and a rotating sleeve 8 are rotatably mounted on the roller 2. The rotating sleeve 8 is rotatably mounted on the roller 2 through a bearing. The rotating shaft 7 and the rotating sleeve 8 are connected in a transmission connection. The cover plate 6 is fixedly connected to the rotating shaft 7, and the rotating sleeve 8 is coaxially fitted into one of them. A first cylindrical gear 9 is mounted on the fixed shaft 4 and the rotating sleeve 8. A power push rod 10 and a self-locking motor 11 are fixedly mounted on the mounting bracket 1. The power push rod 10 is an electric cylinder, but it can also be a pneumatic cylinder or a hydraulic cylinder. A rack 12 is connected to the output end of the power push rod 10. The rack 12 is used to mesh with the first cylindrical gear 9. The self-locking motor 11 is a motor with a brake device, or a motor equipped with a worm gear 18 and a worm 15 reducer. A second cylindrical gear 13 is mounted on the output end of the self-locking motor 11. A third cylindrical gear 14 is mounted on the fixed shaft 4 away from the rotating sleeve 8. The third cylindrical gear 14 meshes with the second cylindrical gear 13.

[0022] Because the rotating sleeve 8 and the fixed shaft 4 are coaxially arranged, the center of the first cylindrical gear 9 can always be determined regardless of the rotation angle of the roller or the position of the cover plate 6. Thus, when loading or unloading is required, the power push rod 10 can be controlled to drive the rack 12, which can accurately mesh with the first cylindrical gear 9, thereby driving the first cylindrical gear 9, the rotating sleeve 8, and the rotating shaft 7 to rotate. The rotating shaft 7 then drives the cover plate 6 to move, automatically opening and closing the opening 5. During loading, the opening 5 is located above the roller 2. When the cover plate 6 opens the opening 5, fasteners can be placed inside the roller 2. After the cover plate 6 closes the opening 5, the mounting bracket 1 is moved, causing the mounting bracket 1 to move the roller 2 to the treatment tank for surface treatment. The self-locking motor 11 drives the second cylindrical gear 13, the third cylindrical gear 14, the fixed shaft 4, and the roller 2 to rotate, ensuring that the fasteners inside the roller 2 are in full contact with the treatment liquid in the treatment tank. During unloading, if... Figure 4 As shown, opening 5 is located at the bottom of roller 2. After the drive cover plate 6 rotates to open opening 5, the fasteners can be directly discharged under gravity.

[0023] In a preferred embodiment, to enable the rotating shaft 7 to drive the rotating sleeve 8, a worm gear 15 is rotatably mounted on the roller 2. Two extension plates 25 are fixed on the roller 2, and the worm gear 15 is rotatably mounted on the extension plates 25 via bearings. This achieves a rotatable connection between the roller 2 and the worm gear 15. A first bevel gear 16 is fixedly mounted on the worm gear 15, and a second bevel gear 17, meshing with the first bevel gear 16, is mounted on the rotating sleeve 8. A worm wheel 18, meshing with the worm gear 15, is mounted on the rotating shaft 7. By driving the first cylindrical gear 9 to rotate, the rotating sleeve 8 and the second bevel gear 17 rotate. The second bevel gear 17 drives the first bevel gear 16 and the worm gear 15 to rotate, and the worm gear 15 drives the worm wheel 18 and the rotating shaft 7 to rotate. The worm wheel 18 and the worm gear 15 also serve a self-locking function, preventing the rotating shaft 7 from rotating when the roller 2 rotates, thus avoiding the opening 5 of the cover plate 6.

[0024] To prevent the rotating sleeve 8 from rotating and causing the cover plate 6 to open the opening 5, a fixing frame 19 is fixed on the roller 2, and a torsion spring 20 is fitted on the rotating sleeve 8. One end of the torsion spring 20 is connected to the rotating sleeve 8, and the other end is connected to the fixing frame 19. The torsion spring 20 provides torque to the rotating sleeve 8, restricting its rotation. In this way, the rotating sleeve 8 and the fixed shaft 4 can remain relatively stationary, allowing the cover plate 6 to stably close the opening 5. When the power push rod 10 drives the rack 12 to move, causing the rack 12 to drive the first cylindrical gear 9 and the rotating sleeve 8 to rotate, the torsion spring 20 will elastically deform, allowing the rotating sleeve 8 to rotate normally.

[0025] In a preferred embodiment, to enable the power push rod 10 to drive the rack 12 to move smoothly in a linear motion, a guide rail 21 is fixed on the mounting bracket 1, and the rack 12 is fixedly connected to the slider of the guide rail 21. The guide rail 21 guides the rack 12, enabling the power push rod 10 to drive the rack 12 to move smoothly in a linear motion, facilitating stable meshing of the rack 12 with the first cylindrical gear 9.

[0026] In a preferred embodiment, to facilitate the connection between the output end of the power push rod 10 and the rack 12, a connecting plate 22 is fixedly attached to the output end of the power push rod 10, and the connecting plate 22 is fixedly connected to the rack 12. The output end of the power push rod 10 is connected to the rack 12 through the connecting plate 22.

[0027] In a preferred embodiment, to facilitate the movement of the mounting frame 1, a lifting lug 23 is fixed to the top of the mounting frame 1. Two lifting lugs 23 are provided, and a lifting device is connected through the lifting lugs 23 to facilitate the movement of the mounting frame 1 to a preset position.

[0028] In a preferred embodiment, to facilitate the rotatable mounting of the rotating shaft 7 on the roller 2, a fixing seat 24 is provided on the roller 2 and fixed on both sides of the opening 5, and the rotating shaft 7 is rotatably mounted on the fixing seat 24 through bearings.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
