Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an automatic cleaning and drying device for automotive pipes. Background Technology

[0002] In the production and maintenance of automotive tubing, its cleanliness is crucial to assembly accuracy, service life, and overall vehicle performance. During processing, storage, and transportation, the inner wall of tubing is prone to residues of cutting fluid, metal shavings, and other impurities, while the outer wall is prone to dust and other stains. If not thoroughly cleaned, these can lead to component failure. Therefore, cleaning and drying are essential steps in the automotive manufacturing industry.

[0003] Current traditional processing methods have significant limitations: First, cleaning is incomplete; existing equipment often struggles to clean both the inner and outer walls of pipe fittings simultaneously, frequently requiring manual assistance to clean the inner walls, which can easily lead to blind spots and scratches. Second, automation is low; processes such as fixing, adjusting, and transferring pipe fittings for drying rely on manual labor, resulting in low efficiency and potential damage to the fittings due to operational errors. Third, drying is ineffective; natural air drying is time-consuming, and localized heating can lead to uneven heating, causing deformation or incomplete drying, especially since moisture is difficult to evaporate from the inside of slender pipe fittings. Fourth, adaptability is poor; it is difficult to meet the processing needs of different pipe fitting specifications, and equipment needs to be readjusted when changing models, resulting in poor versatility.

[0004] Therefore, there is an urgent need for a device that can simultaneously clean the inner and outer walls, has a high degree of automation, provides uniform and efficient drying, and is adaptable to various specifications. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figures 1-6 An automatic cleaning and drying device for automotive pipe fittings is mainly composed of a cleaning tank 1, a cleaning component 2, a limiting mechanism 3, and a drying mechanism 4. The components work together to achieve automatic cleaning and drying of automotive pipe fittings.

[0033] It is worth noting that the cleaning tank 1 is the main supporting structure of the entire device, and is shaped like a hollow barrel. Its interior houses the limiting mechanism 3 and the core working components of the cleaning assembly 2, while its exterior is fixedly connected to the drive structure of the cleaning assembly 2 and the drying mechanism 4, forming a closed cleaning and drying space. The inner bottom wall of the cleaning tank 1 provides the mounting base for the limiting mechanism 3, the inner wall is used to fix the air guide components of the drying mechanism 4, and the outer wall provides connection points for the support structure of the cleaning assembly 2. Overall, it provides a stable framework for the coordinated operation of all components.

[0034] It is worth noting that the limiting mechanism 3 is used to fix the automotive pipes and ensure that the position of the pipes is stable during the cleaning and drying process. Its specific structure and connection relationship are as follows: the limiting base plate 301 has a plate-like structure and is rotatably set on the inner bottom wall of the cleaning tank 1. It can rotate around its own axis on the inner bottom wall of the cleaning tank 1 to provide a platform for placing the pipes.

[0035] Two rectangular holes 302 are symmetrically opened on the surface of the limiting base plate 301, and are symmetrically distributed along the central axis of the limiting base plate 301 to provide space for the installation of the limiting rod 304.

[0036] The limiting rod 304 is a long strip-shaped rod with its two ends fixed to the opposite inner walls of the rectangular hole 302, and it passes horizontally through the rectangular hole 302 to serve as a sliding track for the clamping plate 305.

[0037] There are four clamping plates 305 in total (two in each rectangular hole 302), which are slidably sleeved on the surface of the limiting rod 304 and can slide freely along the length of the limiting rod 304. The two clamping plates 305 cooperate to form a clamping space for the pipe fitting.

[0038] Compression spring 306 is sleeved on the surface of limit rod 304 and located between two clamping plates 305. One end is fixedly connected to the surface of one clamping plate 305 and the other end is fixedly connected to the surface of the other clamping plate 305. Through its own elastic force, it pushes the two clamping plates 305 closer to each other to achieve clamping and fixing of pipes of different diameters.

[0039] The second drive motor 307 is fixedly installed on the lower surface of the cleaning tank 1. Its rotation axis extends upward and passes through the bottom wall of the cleaning tank 1. It is fixedly connected to the center position of the lower surface of the limiting base plate 301. By driving the rotation shaft to rotate, it drives the limiting base plate 301 to rotate synchronously, thereby driving the clamped pipe to rotate.

[0040] It is worth noting that the cleaning component 2 is used to clean the inner and outer walls of the pipes simultaneously, and can achieve flexible adjustment of position and angle. Its specific structure and connection relationship are as follows: the rectangular shell 201 is a hollow rectangular shell, fixed on the outer wall of the cleaning tank 1, and extends perpendicular to the side wall of the cleaning tank 1, providing guidance and support for the lifting movement of the lifting column 202.

[0041] The lifting column 202 has a columnar structure and is slidably installed on the inner wall of the rectangular shell 201. It can slide up and down along the height direction of the rectangular shell 201, and its top extends to the outside of the rectangular shell 201 to drive the extension frame 203 to rise and fall.

[0042] The extension frame 203 is fixedly installed on the top of the lifting column 202 and extends horizontally above the cleaning tank 1. Its surface has a strip-shaped hole to provide space for the installation of the horizontal threaded rod 204 and the sliding of the movable seat 205.

[0043] The horizontal threaded rod 204 is a horizontally arranged threaded rod that is rotatably connected to the inner wall of the strip hole of the extension frame 203. Its two ends are rotatably connected to the two side walls of the strip hole, and it can rotate around its own axis.

[0044] The movable seat 205 has a block-shaped structure and is threadedly connected to the surface of the horizontal threaded rod 204. When the horizontal threaded rod 204 rotates, the movable seat 205 can slide in the slot along the length of the horizontal threaded rod 204 to adjust the horizontal position.

[0045] The adjusting block 206 is rotatably mounted on the lower surface of the movable seat 205 and can rotate around the connection point between itself and the movable seat 205 to adjust the angle of the cleaning rod 207.

[0046] The cleaning rod 207 is rotatably connected to the lower surface of the adjusting block 206 and can change its angle as the adjusting block 206 rotates. A cleaning brush 208 is sleeved on its surface. The two cleaning rods 207 are used together, one of which can be inserted into the inside of the pipe fitting, and the other is attached to the outer wall of the pipe fitting, so as to clean the inner and outer walls of the pipe fitting at the same time. Under the action of the adjusting block 206, the two cleaning brushes 208 can be made to stick tightly to the inner and outer walls of the pipe fitting.

[0047] The cleaning brush 208 is made of flexible bristles and is fitted onto the surface of the cleaning rod 207. As the cleaning rod 207 moves, it comes into contact with the surface of the pipe and removes the stains from the surface of the pipe through friction.

[0048] The first drive motor 209 is fixedly installed at the bottom end of the rectangular shell 201, and its rotation axis extends upward into the interior of the rectangular shell 201 and is fixedly connected to the bottom end of the vertical threaded rod 210; by driving the rotation shaft to rotate, the vertical threaded rod 210 is driven to rotate synchronously.

[0049] The vertical threaded rod 210 is vertically installed inside the rectangular shell 201, and its top end is rotatably connected to the inner top wall of the rectangular shell 201. The surface is threaded. The surface of the lifting column 202 is provided with a threaded groove that matches the vertical threaded rod 210. The lifting column 202 is threadedly connected to the vertical threaded rod 210 through the threaded groove. When the vertical threaded rod 210 rotates, the lifting column 202 slides up and down along the rectangular shell 201 under the action of the thread.

[0050] The water pump 211 is fixedly installed on the surface of the lifting column 202. Its input end is connected to an external water source, and its output end is connected to the strip nozzle 213 through the water delivery hose 212, which is used to deliver clean water to the strip nozzle 213.

[0051] The water supply hose 212 is a flexible pipe. One end is fixedly connected to the output end of the water pump 211, and the other end passes through the mounting plate on the side of the adjusting block 206 and is fixedly connected to the input end of the strip nozzle 213. It can flexibly deform with the movement of the adjusting block 206 to ensure smooth water supply.

[0052] The strip nozzle 213 is fixedly installed on the lower surface of the side mounting plate of the adjusting block 206, with its nozzle facing the direction of the cleaning rod 207 and its position corresponding to the two cleaning rods 207. It is used to spray clean water onto the cleaning brush 208 and the surface of the pipe fitting, and enhances the cleaning effect in conjunction with the cleaning brush 208.

[0053] It should be noted that a drain pipe is installed at the bottom of the cleaning tank 1, and a drain valve is installed on the surface of the drain pipe. The drain pipe is used to discharge the wastewater generated during cleaning.

[0054] The third drive motor 214 is fixedly embedded on the surface of the extension frame 203. Its rotating shaft extends horizontally into the slot of the extension frame 203 and is fixedly connected to one end of the horizontal threaded rod 204. By driving the rotating shaft to rotate, the horizontal threaded rod 204 rotates synchronously, thereby driving the moving seat 205 to slide.

[0055] The adjusting motor 215 is fixedly mounted on the outer side of the movable seat 205. Its rotating shaft extends horizontally into the mounting hole of the movable seat 205 and is fixedly connected to one end of the worm gear 216, providing power for the rotation of the worm gear 216.

[0056] The worm gear 216 is installed in the mounting hole of the movable seat 205. One end is fixedly connected to the rotating shaft of the adjusting motor 215, and the other end is rotatably connected to the inner wall of the mounting hole, so that it can rotate synchronously with the rotation of the adjusting motor 215.

[0057] The rotating shaft 217 is vertically arranged, with its bottom end fixedly connected to the upper surface of the adjusting block 206, and its top end extending upward into the mounting hole of the movable seat 205 and fixedly connected to the center position of the worm gear 218, for transmitting the rotational movement of the worm gear 218 to the adjusting block 206.

[0058] The worm gear 218 is installed in the mounting hole of the movable seat 205, fixedly connected to the top of the rotating shaft 217, and meshes with the worm 216. When the worm 216 rotates, the worm gear 218 drives the rotating shaft 217 to rotate under the meshing action, which in turn drives the adjusting block 206 to rotate, thereby realizing the adjustment of the angle of the cleaning rod 207.

[0059] It is worth noting that the drying mechanism 4 is used to quickly dry the pipe fittings after cleaning. Its specific structure and connection relationship are as follows: the heating box 401 has a hollow box structure and is fixedly connected to the outer side wall of the cleaning tank 1. The interior forms a heating space to provide a place for air heating.

[0060] The arc-shaped air guide shell 402 has an arc-shaped shell structure and is fixed on the inner wall of the cleaning tank 1. Its curvature is adapted to the curvature of the inner wall of the cleaning tank 1, which can guide the hot air evenly to the pipes inside the tank.

[0061] Air outlets 403 are formed on the surface of the arc-shaped air guide shell 402. There are several of them, and they are evenly distributed on the inner side of the arc-shaped air guide shell 402 (the side facing the center of the barrel), which are used to guide hot air from the inside of the arc-shaped air guide shell 402 into the cleaning barrel 1.

[0062] The fan 404 is fixedly embedded on the surface of the heating box 401, with its air outlet facing the inside of the heating box 401, and is used to draw outside air into the heating box 401 and drive the air flow.

[0063] The electric heating mesh 405 is fixedly installed on the inner wall of the heating box 401, located between the air outlet of the fan 404 and the input end of the air duct 406. When powered on, it can generate heat to heat the air drawn in by the fan 404.

[0064] The air duct 406 is a hollow pipe. One end is fixedly connected to the lower surface of the heating box 401 and communicates with the interior of the heating box 401. The other end extends through the side wall of the cleaning tank 1 into the interior of the cleaning tank 1 and communicates with the interior of the arc-shaped air guide shell 402. It is used to guide the hot air in the heating box 401 into the arc-shaped air guide shell 402.

[0065] Working Principle: 1. Fitting Fixing: First, place the automotive fitting to be cleaned on the limiting base plate 301, and fix it using the clamping plate 305 and compression spring 306 on the surface of the limiting rod 304. The elastic force of the compression spring 306 pushes the two clamping plates 305 closer together, automatically adjusting the clamping distance according to the diameter of the fitting, ensuring that the fitting is stably clamped on the limiting base plate 301.

[0066] II. Position Adjustment of Cleaning Component 2: Start the first drive motor 209, whose rotating shaft drives the vertical threaded rod 210 to rotate. The lifting column 202 slides up and down along the rectangular shell 201 under the cooperation of the threaded groove and the vertical threaded rod 210, thereby adjusting the height of the extension frame 203 and the cleaning rod 207, aligning the cleaning rod 207 with the pipe fitting. Then, start the third drive motor 214, whose rotating shaft drives the horizontal threaded rod 204 to rotate. The moving seat 205 slides along the horizontal threaded rod 204, adjusting the horizontal position of the cleaning rod 207, so that the two cleaning rods 207 are respectively aligned with the inside and outside of the pipe fitting.

[0067] 3. Cleaning angle adjustment: Start the adjustment motor 215, its rotating shaft drives the worm 216 to rotate, the worm 216 meshes with the worm wheel 218 to drive the rotating shaft 217 to rotate, which in turn drives the adjustment block 206 to rotate, adjusting the angle of the cleaning rod 207 to ensure that the cleaning brush 208 is in close contact with the inner and outer walls of the pipe fitting.

[0068] IV. Cleaning Operation: Turn on the water pump 211, and clean water is delivered to the strip nozzle 213 through the water supply hose 212. The strip nozzle 213 sprays water onto the cleaning brush 208 and the surface of the pipe fitting. At the same time, the pipe fitting is rotated under the action of the limiting mechanism 3, so that the cleaning brush 208 performs friction cleaning on the inner and outer walls of the pipe fitting.

[0069] V. Drying Operation: Start the fan 404 to draw outside air into the heating box 401. When the air passes through the electric heating grid 405, it is heated into hot air. The hot air enters the arc-shaped air guide shell 402 through the air guide pipe 406, and then is blown evenly onto the surface of the pipe through the air outlet 403 on the surface of the arc-shaped air guide shell 402. At the same time, the second drive motor 307 continues to drive the pipe to rotate, so that all parts of the pipe are heated evenly, achieving rapid drying.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
