Technical Field
[0001] This utility model relates to the technical field of rust-preventing oiling devices for automotive parts, and in particular to an rust-preventing oiling device for automotive parts. Background Technology
[0002] In the automotive manufacturing industry, rust prevention treatment of parts is a crucial step in ensuring vehicle quality and lifespan. Rust prevention components, as the core parts for achieving efficient and precise rust prevention, directly impact the effectiveness of the rust prevention.
[0003] Traditional rust prevention treatments for automotive parts present numerous problems in both the rust removal and oiling stages. For rust removal, manual methods are extremely inefficient, requiring workers to manually grind and clean rust from the parts' surfaces using tools such as sandpaper and wire brushes. This method is not only labor-intensive and time-consuming but also struggles to ensure consistent rust removal, often resulting in incomplete removal and poor rust prevention after subsequent oiling. Even with simple rust removal equipment, the lack of precise control and stable performance makes it difficult to completely and evenly remove rust from complex-shaped parts. Residual rust spots become potential corrosion points, accelerating the re-rusting of parts.
[0004] The oiling process also faces challenges. Traditional oiling equipment is mostly simple in structure and cannot be flexibly adjusted according to the different sizes and shapes of parts. For some small, precision parts, traditional oiling equipment may apply too much oil, wasting rust-preventive oil and forming an uneven oil film on the surface of the parts, affecting appearance and subsequent assembly. For large parts, uneven oiling may occur, leaving some areas unprotected. Traditional oiling equipment cannot achieve integrated rust removal and oiling operations, requiring parts to be transferred between different machines, increasing the complexity and time cost of the production process and reducing production efficiency.
[0005] With the rapid development of the automotive industry, the requirements for the production efficiency and quality of auto parts are becoming increasingly stringent. Existing rust prevention methods and equipment can no longer meet market demands, and there is an urgent need to develop a new type of rust prevention component that can efficiently remove rust, precisely apply oil, and flexibly adapt to different parts, in order to improve the rust prevention level of automotive parts and ensure the overall performance and quality of automobiles.

[0025] 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.
[0026] Example 1
[0027] Most oiling equipment has a simple structure and cannot be flexibly adjusted according to the different sizes and shapes of parts. For some small precision parts, traditional oiling equipment may apply too much oil, resulting in wasted rust-preventive oil and uneven oil film on the surface of the parts, affecting the appearance and subsequent assembly. For large parts, uneven oiling may occur, leaving some areas unprotected. Traditional oiling equipment cannot achieve integrated rust removal and oiling operations, requiring the transfer of parts between different devices, increasing the complexity and time cost of the production process and reducing production efficiency. This embodiment provides an oiling device for rust prevention of automotive parts. Please refer to... Figures 1-4 An embodiment provides a rust-preventing oiling device for automotive parts, including a device body 1. The device body 1 is provided with a connecting mechanism 2, which includes a limiting component 21 disposed on the right section of the device body 1, a rust-preventing component 22 disposed on the left section of the device body 1, and a connecting component 23 disposed on the top of the device body 1. The rust-preventing component 22 includes a drive motor 221, and a drive gear 222 is fixedly connected to the output end of the drive motor 221. A meshing gear ring 223 meshes with the inner side of the drive gear 222, and a fixed component is rotatably connected to the inner wall of the meshing gear ring 223. A fixed frame 224 is fixedly mounted on the top of the fixed frame 224. A fixed ring 225 is fixedly connected to the inner wall of the fixed frame 224. A rotating screw 226 is threadedly connected to the inner wall of the fixed ring 225. An arc-shaped clamp 227 is rotatably connected to the top of the rotating screw 226. A fixed slide rod 228 is fixedly connected to the outer wall of the arc-shaped clamp 227. A limit frame 2210 is slidably connected to the outer wall of the meshing toothed ring 223. An annular frame 2211 is fixedly connected to the inner wall of the meshing toothed ring 223. A rust removal scraper 2212 is fixedly connected to the inner wall of the annular frame 2211.
[0028] In this embodiment, the drive motor 221 is fixedly installed on the top of the top frame 211, providing power for the operation of the entire anti-rust assembly 22. The device can use a Y90S-2 drive motor, which features small size, high speed, and stable output torque, meeting the power requirements of the anti-rust assembly 22. After the drive motor 221 is powered on, its output drives the drive gear 222 to rotate at high speed. The drive gear 222 meshes with the inner meshing gear ring 223, and the rotation of the drive gear 222 causes the meshing gear ring 223 to rotate around its central axis. Because the inner wall of the meshing gear ring 223 and the fixed frame 224 are rotatably connected, the fixed frame 224 can remain relatively stable when the meshing gear ring 223 rotates; the oil injector 229 fixedly installed on the top of the fixed frame 224 also remains stable; the oil injector 229 can be a high-pressure atomizing oil injector of model F332-10, which has a good atomization effect and can evenly spray the rust-preventive oil onto the surface of the parts to ensure the rust prevention effect; the oil injector 229 is connected to an external rust-preventive oil pipe, and the rust-preventive oil is delivered to the oil injector 229 through the oil pipe, and under the action of the oil injector 229, the rust-preventive oil is evenly sprayed ... Rust-preventive oil is atomized and sprayed onto the surface of the parts; the fixing ring 225 fixedly connected to the inner wall of the fixing bracket 224 is threadedly connected to the rotating screw 226; when it is necessary to further fix parts of different shapes and sizes, the rotating screw 226 can be manually rotated; as the rotating screw 226 rotates, due to the thread action between it and the fixing ring 225, the rotating screw 226 will move up and down along the axial direction; the arc-shaped clamp 227 rotatably connected to the top of the rotating screw 226 will also move up and down accordingly. By adjusting the distance between the two symmetrically arranged arc-shaped clamps 227, a tight fit can be achieved. The same size components provide good limiting function, ensuring that the components will not shake during oiling and rust removal. At the same time, the fixed slide rod 228, which is fixedly connected to the outer wall of the arc-shaped clamp 227, slides on the inner wall of the fixed ring 225, providing guidance and stable support for the movement of the arc-shaped clamp 227. The outer wall of the meshing toothed ring 223 is slidably connected to the limiting frame 2210, which is fixedly connected to the top of the top frame 211. The limiting frame 2210 limits and guides the movement of the meshing toothed ring 223, ensuring that the meshing toothed ring 223 maintains a stable trajectory during rotation and does not deviate.
[0029] Furthermore, the drive motor 221 is fixedly installed on the top of the top frame 211, and the limit bracket 2210 is fixedly connected to the top of the top frame 211; the arc-shaped clamping plate 227 is symmetrically arranged on the top and bottom to limit the parts; the oil injector 229 is connected to the external anti-rust oil pipe; the fixed slide rod 228 is slidably connected to the inner wall of the fixed ring 225; and the rust removal scraper 2212 is used to remove rust from the outer wall of the parts.
[0030] Furthermore, as the rotating screw 226 rotates, due to the threaded action between it and the fixed ring 225, the rotating screw 226 will move up and down axially; the arc-shaped clamp 227 rotatably connected to the top of the rotating screw 226 will also move up and down accordingly. By adjusting the distance between the two symmetrically arranged arc-shaped clamps 227, parts of different sizes can be tightly fitted, providing a good limiting effect and ensuring that the parts will not shake during oiling and rust removal; at the same time, the fixed slide rod 228 fixedly connected to the outer wall of the arc-shaped clamp 227 slides on the inner wall of the fixed ring 225, providing guidance and stable support for the movement of the arc-shaped clamp 227.
[0031] Example 2
[0032] Based on embodiment 1, the limiting component 21 includes a top frame 211, an electric screw 212 is connected to the inner wall of the top frame 211, a connecting rod 213 is threaded to the outer wall of the electric screw 212, a limiting ring 214 is fixedly connected to the inner side of the connecting rod 213, and limiting screws 215 are threaded to the inner walls of the upper and lower ends of the limiting ring 214; the connecting component 23 includes a side frame 231, a pad 232 is fixedly connected to the inner wall of the side frame 231, and a collection frame 233 is fixedly installed on the inner wall of the pad 232.
[0033] In this embodiment, the top frame 211 serves as the basic frame of the limiting component 21, fixedly connected to the top of the side frame 231, and plays a role in supporting and positioning other components. When rust-proofing and oiling operations are required for automotive parts, the electric screw 212 is activated, and the electric screw 212 begins to rotate after being powered on. Since the electric screw 212 and the connecting rod 213 are threadedly connected, as the electric screw 212 rotates, the connecting rod 213 will move linearly along its axial direction on the inner wall of the top frame 211. By controlling the forward and reverse rotation and the number of rotations of the electric screw 212, the position of the connecting rod 213 within the top frame 211 can be precisely adjusted. The limiting ring 214 fixedly connected to the inner side of the connecting rod 213 will move synchronously with the connecting rod 213, thereby enabling the application of rust-proofing and oiling to automotive parts of different sizes. The initial positioning is achieved by the limiting ring 214. Once the limiting ring 214 moves to the appropriate position and the automotive parts are placed inside it, the limiting screws 215 on the inner walls of the upper and lower ends of the limiting ring 214 can be tightened to further secure the parts, ensuring that they will not shift during subsequent operations such as oiling, thus guaranteeing the accuracy and stability of the operation. The side frame 231 is symmetrically arranged on both sides of the top of the device body 1, providing an installation base for the entire connecting assembly 23. The pad 232 fixedly connected to the inner wall of the side frame 231 provides support and buffering. The collection frame 233 fixedly installed on the inner wall of the pad 232 is used to collect the rust-preventive oil dripping during the oiling process, preventing the rust-preventive oil from dripping onto the workbench, causing waste and environmental pollution, realizing the recycling of the rust-preventive oil, and improving resource utilization.
[0034] Furthermore, the top frame 211 is fixedly connected to the top of the side frame 231, and the connecting rod 213 is slidably connected to the inner wall of the top frame 211; the side frame 231 is symmetrically arranged on both sides of the top of the device body 1.
[0035] Furthermore, the limiting ring 214, which is fixedly connected to the inner side of the connecting rod 213, moves synchronously with the connecting rod 213, thereby achieving initial positioning of automotive parts of different sizes. When the limiting ring 214 moves to the appropriate position, after the automotive parts are placed inside the limiting ring 214, the parts can be further fixed by tightening the limiting screws 215 on the inner walls of the upper and lower ends of the limiting ring 214, ensuring that the parts will not shift during subsequent operations such as oiling, thus ensuring the accuracy and stability of the operation. The side frame 231 is symmetrically arranged on both sides of the top of the device body 1, providing an installation base for the entire connecting assembly 23.
[0036] Working principle: The top frame 211 serves as the basic frame of the limiting component 21, fixedly connected to the top of the side frame 231, and plays a role in supporting and positioning other components. When rust-proofing and oiling operations are required on automotive parts, the electric screw 212 is activated, and the electric screw 212 begins to rotate after being energized. Since the electric screw 212 and the connecting rod 213 are threadedly connected, as the electric screw 212 rotates, the connecting rod 213 will move linearly along its axial direction on the inner wall of the top frame 211. By controlling the forward and reverse rotation and the number of rotations of the electric screw 212, The position of the connecting rod 213 within the top frame 211 can be precisely adjusted; the limiting ring 214 fixedly connected to the inner side of the connecting rod 213 will move synchronously with the connecting rod 213, thereby achieving initial positioning of automotive parts of different sizes; when the limiting ring 214 moves to the appropriate position, after the automotive parts are placed inside the limiting ring 214, the parts can be further fixed by tightening the limiting screws 215 on the inner walls of the upper and lower ends of the limiting ring 214, ensuring that the parts will not shift during subsequent operations such as oiling, thus ensuring the accuracy and stability of the operation;
[0037] The drive motor 221 is fixedly installed on the top of the top frame 211, providing power for the operation of the entire rust-proof assembly 22. This device can use a Y90S-2 drive motor, which features small size, high speed, and stable output torque, meeting the power requirements of the rust-proof assembly 22. After the drive motor 221 is powered on, its output drives the drive gear 222 to rotate at high speed. The drive gear 222 meshes with the inner meshing gear ring 223, and the rotation of the drive gear 222 causes the meshing gear ring 223 to rotate around its central axis. Due to the meshing... The inner wall of the gear ring 223 and the fixed frame 224 are rotatably connected, so the fixed frame 224 can remain relatively stable when the gear ring 223 rotates; the oil injector 229 fixedly installed on the top of the fixed frame 224 also remains stable; the oil injector 229 can be a high-pressure atomizing oil injector of model F332-10, which has a good atomization effect and can evenly spray the rust-preventive oil onto the surface of the parts to ensure the rust prevention effect; the oil injector 229 is connected to an external rust-preventive oil pipe, and the rust-preventive oil is delivered to the oil injector 229 through the oil pipe. Under the action of the oil injector 229, the rust-preventive oil is atomized. The solution is sprayed onto the surface of the parts; the fixing ring 225 fixedly connected to the inner wall of the fixing bracket 224 is threadedly connected to the rotating screw 226; when it is necessary to further fix parts of different shapes and sizes, the rotating screw 226 can be manually rotated; as the rotating screw 226 rotates, due to the thread action between it and the fixing ring 225, the rotating screw 226 will move up and down along the axial direction; the arc-shaped clamp 227 rotatably connected to the top of the rotating screw 226 will also move up and down accordingly. By adjusting the distance between the two symmetrically arranged arc-shaped clamps 227, parts of different sizes can be tightly fitted. The sized components provide good limiting function, ensuring that the components do not shake during oiling and rust removal; at the same time, the fixed slide rod 228, which is fixedly connected to the outer wall of the arc-shaped clamp 227, slides on the inner wall of the fixed ring 225, providing guidance and stable support for the movement of the arc-shaped clamp 227; the outer wall of the meshing toothed ring 223 is slidably connected to the limiting frame 2210, which is fixedly connected to the top of the top frame 211. The limiting frame 2210 limits and guides the movement of the meshing toothed ring 223, ensuring that the meshing toothed ring 223 maintains a stable trajectory during rotation and does not deviate;
[0038] The annular frame 2211 is fixedly connected to the inner wall of the meshing toothed ring 223, and the rust-removing scraper 2212 is fixedly connected to the inner wall of the annular frame 2211. It will rotate together with the meshing toothed ring 223. When the parts are placed in the device and fixed, the rust-removing scraper 2212 will contact the outer wall of the parts during rotation and remove the rust on the outer wall of the parts through physical friction. This prepares the parts for subsequent oiling operations, ensuring that the rust-preventive oil can better adhere to the surface of the parts and improve the rust prevention effect.
[0039] The side frames 231 are symmetrically arranged on both sides of the top of the device body 1, providing an installation base for the entire connecting assembly 23; the pads 232 fixedly connected to the inner wall of the side frames 231 provide support and buffer; the collection frame 233 fixedly installed on the inner wall of the pads 232 is used to collect the rust-preventive oil dripping during the oiling process, avoiding the rust-preventive oil from dripping onto the workbench, causing waste and environmental pollution, realizing the recycling of rust-preventive oil, and improving resource utilization.
