Description
Technical Field
[0001] This utility model relates to the field of cleaning component technology, and in particular to a lightweight automotive axle housing cleaning component. Background Technology
[0002] The axle housing is a crucial component of the automotive transmission system, responsible for supporting and protecting key components such as the final drive and differential. With the trend towards lightweight vehicles, axle housing materials are increasingly adopting lightweight materials such as high-strength steel and aluminum alloys to reduce overall vehicle weight, improve fuel economy, and reduce emissions, thereby enhancing vehicle performance and reducing energy consumption. Through innovations in materials science, structural design, and manufacturing processes, lightweight automotive axle housings have achieved multiple goals of weight reduction, efficiency improvement, and energy saving. When cleaning the axle housing of a vehicle, operators often need to use cleaning equipment.
[0003] In existing technologies, after operators complete the axle housing cleaning operation using a cleaning device, residual moisture is usually treated by natural air drying. However, natural air drying is subject to uncontrollable factors such as ambient temperature, humidity, and air circulation, resulting in a long and unstable drying cycle. In particular, in high humidity environments, a continuous water film can easily form, increasing the redundant time in the production process. Furthermore, water stains remaining on the axle housing surface are prone to electrochemical corrosion reactions with the metal substrate during evaporation. Lightweight materials such as aluminum alloys and high-strength steel are especially sensitive to water stains. Long-term accumulation will lead to defects such as pitting corrosion and oxide layer peeling on the axle housing surface, thereby weakening its mechanical strength and fatigue life, reducing the reliability of vehicle operation and maintenance costs. Therefore, it is necessary to improve the automotive lightweight axle housing cleaning component to solve the above problems. Utility Model Content

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] Please see Figure 1 - Figure 9 This utility model provides an embodiment of a lightweight automotive axle housing cleaning assembly, including a base frame 1, a water storage base 4 fixedly connected to the bottom of the base frame 1, a cleaning tank 5 fixedly connected to the top of the base frame 1, a door panel 6 rotatably connected to the cleaning tank 5 via a rotating component, a water trough 7 formed on the base frame 1, a clamping assembly disposed on the base frame 1, a smooth rod 29 rotatably connected inside the cleaning tank 5, a fan 210 fixedly connected to the inner side of the smooth rod 29, a mounting bracket 211 fixedly connected to the fan 210, and a heating pipe 212 fixedly connected to the inner wall of the mounting bracket 211. The fan 210 blows air onto the cleaned axle housing, and the heating pipe 212 amplifies the air blown out by the fan 210. Heating is performed, and water for cleaning the bridge housing flows into the water storage base 4 through the water flow channel 7. The cleaned bridge housing is blown by the fan 210, and the heating tube 212 is activated to heat the air blown by the fan 210, thus drying the cleaned bridge housing. The fans 210 on both sides rotate synchronously in opposite directions to increase the drying range of the fans 210, thereby improving the drying efficiency of the bridge housing and enhancing the practicality of the device. The clamping component can easily clamp bridge housings of different shapes, improving the stability of the cleaning process. Furthermore, by rotating the rotating base 35, the bridge housing is rotated, which increases the cleaning range of the bridge housing and improves the cleaning efficiency.
[0028] Please see Figure 2 - Figure 6In this embodiment, nine sets of water troughs 7 are symmetrically distributed on the base frame 1 to facilitate the downward flow of water after cleaning, thereby improving the collection efficiency of clean water and avoiding water waste. An inlet pipe 21 connected to the inside of the cleaning tank 5 is fixedly connected to the outside. A high-pressure nozzle 22 for spraying water to clean the bridge housing is fixedly connected to the inlet pipe 21. A first motor 24 is fixedly connected to the cleaning tank 5, and a first bidirectional threaded rod 26 is fixedly connected to the output end of the first motor 24. A first... A semicircular block 25 and a first bidirectional threaded rod 26 are rotatably connected inside the first semicircular block 25. A toothed plate 27 is slidably connected inside the cleaning tank 5 and threaded to the outside of the first bidirectional threaded rod 26. A gear 28 is fixedly connected to the smooth rod 29, and the toothed plate 27 meshes with the outside of the gear 28. A frame 213 is provided inside the water storage base 4.

A mounting frame 215 is fixedly connected to the frame 213 and is bolted to the water storage base. 4. A water outlet pipe 23 is fixedly connected to the water storage base 4. By starting the fan 210, air is blown onto the cleaned bridge housing. Then, by starting the heating pipe 212, the air blown by the fan 210 is heated to dry the cleaned bridge housing. The fans 210 on both sides rotate synchronously in opposite directions to increase the drying range of the fans 210, thereby improving the drying efficiency of the bridge housing and enhancing the practicality of the device. Two sets of toothed plates 27 are provided, and the two sets of toothed plates 27 are symmetrically distributed on the first bidirectional threaded rod 26. Furthermore, the cleaning tank 5 has corresponding slots at the corresponding positions of the two sets of toothed plates 27. Both sets of toothed plates 27 slide within the slots of the cleaning tank 5, thereby limiting their position and improving the practicality of the device. The water storage base 4 has corresponding slots at the corresponding positions of the frame 213. The frame 213 is set within the slots of the water storage base 4, allowing for easy installation and disassembly of the mounting frame 215, filter plate 214, and frame 213 via bolts. This facilitates the treatment of residues collected inside the frame 213 and improves the recycling of clean water.
[0029] Please see Figure 7 - Figure 9In this embodiment, the clamping assembly includes a second motor 31 fixedly connected to the base frame 1, a fixed frame 32 fixedly connected to the top of the base frame 1, a second bidirectional threaded rod 33 rotatably connected inside the fixed frame 32, a moving block 34 slidably connected inside the fixed frame 32, a rotating seat 35 rotatably connected inside the moving block 34, a scale 36 fixedly connected to the moving block 34, a protective cover 310 fixedly connected to the scale 36, a worm gear 37 fixedly connected to the rotating seat 35, a worm 38 meshing with the outside of the worm gear 37, and a worm 38 fixedly connected to the moving block 35. The second semicircular block 39 on block 34, the clamping frame 311 fixedly connected to the inner side of the rotating seat 35, the fixing sleeve 312 fixedly connected to the inside of the clamping frame 311, the clamping pin 313 slidably connected to the inside of the clamping frame 311, the limiting plate 314 fixedly connected to the outside of the clamping pin 313, the spring 315 fixedly connected between the clamping frame 311 and the limiting plate 314, the second bidirectional threaded rod 33 fixedly connected to the output end of the second motor 31, the second bidirectional threaded rod 33 rotatably connected to the inside of the cleaning tank 5, and the moving block 34 threadedly connected to the second bidirectional threaded rod 39 on block 34. The worm gear 37 is located outside the worm rod 33, and the worm 38 is located inside the protective cover 310. The worm 38 is rotatably connected inside the second semicircular block 39. The clamping pin 313 is slidably connected inside the fixed sleeve 312, and the limiting plate 314 is slidably connected inside the clamping frame 311. The clamping assembly facilitates the clamping of bridge shells of different shapes, improving the stability of cleaning. By rotating the rotating seat 35, the bridge shell is rotated, increasing the cleaning range and improving the cleaning efficiency. The moving block 34 is provided with two sets of... Two sets of moving blocks 34 are symmetrically distributed on the second bidirectional threaded rod 33, and the fixed frame 32 has matching grooves at corresponding positions of the two sets of moving blocks 34. Both sets of moving blocks 34 slide in the grooves of the fixed frame 32, which facilitates clamping of bridge shells of different shapes and improves the clamping stability of the bridge shell. The rotating seat 35 has matching pointers at corresponding positions of the scale 36. The pointers rotate with the rotating seat 35, which facilitates reference for the operator and improves the accuracy of the bridge shell rotation and the cleaning efficiency of the bridge shell.
[0030] During operation, the operator opens door panel 6, placing the bridge housing to be cleaned in the center of cleaning tank 5. The second motor 31 is then activated, causing the second bidirectional threaded rod 33 to rotate within the fixed frame 32 and cleaning tank 5. This rotates two sets of moving blocks 34 closer together, bringing them into contact with the shape of the bridge housing via the sliding clamping pin 313 inside the clamping frame 311. A spring 315 connects the limiting plate 314 and the clamping frame 311, clamping bridge housings of different shapes. Door panel 6 is then closed, and the operator introduces external water into the inlet pipe 21, allowing the high-pressure nozzle 22 to rinse and clean the bridge housing. After cleaning one side, the operator opens door panel 6 and rotates the worm gear 38, causing the bridge housing to rotate for a thorough rinse. The cleaned water flows through the water trough 7 into the water storage base 4. The water flows and falls onto the filter plate 214, facilitating the collection of impurities on the water. The filtered water then falls into the water storage base 4, and is discharged to the outside through the outlet pipe 23. By starting the motor on the fan 210, the fan 210 blows air onto the cleaned bridge shell. Then, by starting the heating pipe 212, the air blown out by the fan 210 is heated, which dries the cleaned bridge shell. At this time, by starting the first motor 24, the first bidirectional threaded rod 26 is rotated and connected to the inside of the first semicircular block 25. Two sets of toothed plates 27 are threaded to the outside of the first bidirectional threaded rod 26, which drives the two sets of toothed plates 27 to move synchronously in opposite directions. Through the gears 28 meshing on the outside of the two sets of toothed plates 27, the blowing angle of the two sets of fans 210 is adjusted, causing the fans 210 to rotate back and forth, increasing the drying range of the bridge shell and improving the drying efficiency of the bridge shell.
[0031] Through the above steps, the fan 210 is activated to blow air onto the cleaned axle housing, and the heating tube 212 is activated to heat the air blown out by the fan 210, thus drying the cleaned axle housing. The fans 210 on both sides rotate synchronously in opposite directions to increase the drying range of the fans 210 and improve the drying efficiency of the axle housing. This solves the problem that natural air drying is subject to uncontrollable factors such as ambient temperature and humidity and air circulation, resulting in a long and unstable drying cycle, which increases the redundancy time in the production process and reduces the reliability and maintenance cost of the vehicle.
