Description

Technical Field

[0001] This utility model relates to the field of vehicle frame processing technology, specifically a vehicle frame processing device. Background Technology

[0002] As the supporting structure of a car, the car frame is mostly made of steel. Steel is easily corroded when exposed to air. During the manufacturing process, the car frame usually needs to be painted. The paint can form a protective film on the surface of the frame, which isolates air and moisture, thereby extending the service life of the frame.

[0003] A Chinese patent with publication number CN214107558U discloses a painting device for a swing-type subframe, which includes a base plate; a liquid pump, a fixed head plate, and an electric push rod are sequentially arranged at the top of the base plate; a spray head is arranged on the inner wall of the fixed head plate, and multiple sets of spray heads are evenly arranged; a support plate is arranged at the top of the fixed head plate, and a motor is arranged at the top of the support plate; the motor shaft of the motor passes through the bottom of the support plate, and an iron chain is connected to the motor shaft, with a hook connected to the bottom of the iron chain; this utility model, by setting multiple sets of spray heads and setting the subframe on a rotating mechanism, will achieve a rotating spraying effect during the painting process, greatly improving the quality and efficiency of painting.

[0004] The aforementioned frame painting device lacks a drying mechanism, requiring the frame to dry naturally after painting. This process typically takes a long time, reducing production efficiency. During natural drying, the frame is highly susceptible to environmental factors such as humidity and temperature. Due to uneven distribution of humidity and temperature, natural drying may result in uneven coating drying, leading to problems such as color difference and inconsistent gloss. Therefore, a frame processing device is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a vehicle frame processing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A vehicle frame processing device of this utility model includes a base, a housing mounted on the base, a first motor mounted on the top of the housing, an output end of the first motor connected to a hollow sleeve, a movable rod disposed inside the hollow sleeve, a hook fixedly connected to the bottom end of the movable rod, a sliding groove formed on the hollow sleeve, a sliding rod disposed inside the sliding groove, one end of the sliding rod fixedly connected to the movable rod, and a locking nut rotatably fitted to the other end of the sliding rod via a threaded engagement. An air outlet is fixedly connected to one inner wall of the housing, a shell is fixedly connected to the outer wall of the housing, and a guide pipe connects the shell and the air outlet. A support base is fixedly connected between the shell and the base, a spiral heating tube is disposed inside the shell, two support rods are fixedly connected to the inner wall of the shell, and a second motor is fixedly connected between the two support rods. The output end of the second motor is mounted with… Equipped with a fan, after the frame is painted, a drying mechanism is installed to quickly cure and dry the coating on the frame surface. A second electric motor is activated, causing the fan to rotate. With the assistance of a spiral heating element, the heated high-temperature gas flows through a guide pipe into the air outlet, and is then sprayed onto the frame surface. Simultaneously, the first electric motor causes the hollow sleeve to rotate, driving the hook and the frame it is attached to. As the frame rotates, the high-temperature gas evenly covers the surface, achieving uniform drying. This allows for rapid and uniform drying of the painted frame. Compared to natural drying, the drying mechanism significantly shortens the drying time, thus improving production efficiency. Furthermore, the drying mechanism helps the coating cure better, avoiding problems such as uneven drying, blistering, and cracking that can occur during natural drying, ensuring a more stable and reliable coating quality on the frame surface.

[0007] Preferably, a filter screen is provided at the port of the air inlet pipe of the housing, a vertical plate is fixed to the base, a third motor is installed on the vertical plate, a rotating rod is connected to the output end of the third motor, a scraper is fixed to the end of the rotating rod, and the scraper is in contact with the outer surface of the filter screen. In order to avoid the filter screen from becoming clogged, it needs to be cleaned regularly. By setting up a scraping mechanism, the third motor is started, and with the cooperation of the limiting collar, the rotating rod drives the scraper to rotate stably, thereby regularly scraping and cleaning the dust and impurities attached to the filter screen, preventing the filter screen from becoming clogged, and ensuring the smooth progress of subsequent drying operations.

[0008] Preferably, an L-shaped plate is fixed to the side wall of the vertical plate, and a limiting collar is installed on the L-shaped plate. The rotating rod passes through the limiting collar. When using the device, the limiting collar can limit the rotation of the rotating rod, so that the rotating rod can rotate smoothly.

[0009] Preferably, two fixing sleeves are fixed to the outer wall of the housing away from the shell. The two fixing sleeves cooperate to fix a hollow tube. Multiple branch pipes are connected to the hollow tube. The other end of each branch pipe is connected to a nozzle, and the nozzle is located inside the housing. Each branch pipe is equipped with a one-way valve. A storage tank is provided on the base. A support block is fixed to the top side of the base. A pump body is installed on the support block. The input port of the pump body is connected to a liquid extraction pipe, and the output port of the pump body is connected to a delivery pipe. The other end of the delivery pipe is connected to the hollow tube. When painting the frame, the frame to be processed is first hung on the hook. Then, the pump body is started, so that the paint in the storage tank flows into the hollow tube through the delivery pipe. Finally, it is sprayed onto the surface of the frame through the nozzle. At the same time, the first motor is started, so that the hollow sleeve drives the hook and the frame it is hanging to rotate. As the frame rotates, the paint can be evenly sprayed onto the surface of the frame, making the coating on the surface of the frame smoother and flatter, thus improving the overall quality of the product.

[0010] Preferably, a fourth motor is installed on the top of the storage tank, and the output end of the fourth motor is connected to a stirring shaft. Multiple stirring blades are fixed on the stirring shaft, and a liquid injection pipe is connected to the top of the storage tank. During the storage of the paint, layering, sedimentation, or clumping may occur. By setting up a stirring mechanism and starting the fourth motor, the stirring shaft drives the stirring blades to rotate, thereby stirring the paint in the storage tank, making the paint evenly mixed, avoiding layering, sedimentation, or clumping, and ensuring that the paint remains uniform before spraying, thereby improving the spraying quality.

[0011] The advantages of this utility model are:

[0012] 1. After the frame of this utility model is painted, in order to quickly cure and dry the coating on the frame surface, a drying mechanism is set up. The second motor is started to make the fan rotate. With the cooperation of the spiral heating tube, the heated high-temperature gas flows into the air outlet through the guide pipe. Finally, the high-temperature gas is sprayed onto the frame surface through the air outlet. With the cooperation of the first motor, the cavity sleeve drives the hook and the frame it is attached to to rotate. As the frame rotates, the high-temperature gas can evenly cover the frame surface, achieving uniform drying of the frame. This can achieve rapid and uniform drying of the frame after painting. Compared with natural drying, the drying mechanism greatly shortens the drying time, thereby improving production efficiency. At the same time, by setting up the drying mechanism, it helps the coating to cure better and avoids problems such as uneven drying, coating blistering, and cracking that may occur during natural drying. This ensures that the coating quality on the frame surface is more stable and reliable.

[0013] 2. When painting a vehicle frame, this utility model first hangs the frame to be processed on the hook, then starts the pump to allow the paint in the storage tank to flow into the hollow tube through the delivery pipe, and finally sprays it onto the surface of the frame through the nozzle. At the same time, the first motor is started, causing the hollow sleeve to drive the hook and the frame it is hanging on to rotate. As the frame rotates, the paint can be evenly sprayed onto the surface of the frame, resulting in a smoother and flatter coating on the surface of the frame, thus improving the overall quality of the product.

Subsequently, to ensure the rapid curing and drying of the coating on the frame surface, a drying mechanism is installed. The second motor 16 is activated, causing the fan 17 to rotate. With the assistance of the spiral heating tube 14, the heated high-temperature gas flows into the air outlet 10 through the guide tube 12. Finally, the high-temperature gas is sprayed onto the frame surface through the air outlet 10. With the assistance of the first motor 3, the cavity sleeve 4 drives the hook 6 and the frame it is attached to to rotate. As the frame rotates, the high-temperature gas can evenly cover the frame surface, achieving uniform drying of the frame. This allows for rapid and uniform drying of the frame after painting. Compared to natural drying, the drying mechanism significantly shortens the drying time, thereby improving production efficiency. At the same time, by setting up the drying mechanism, the coating can be better cured, avoiding problems such as uneven drying, coating blistering, and cracking that may occur during natural drying. This ensures that the coating quality on the frame surface is more stable and reliable.

During long-term use, dust and impurities will accumulate on the filter screen 18. If it is not cleaned in time, it may become clogged. In order to avoid the filter screen 18 from becoming clogged, it needs to be cleaned regularly. By setting up a scraping mechanism, the third motor 20 is started. With the cooperation of the limiting collar 24, the rotating rod 21 drives the scraper 22 to rotate stably, thereby regularly scraping and cleaning the dust and impurities attached to the filter screen 18, preventing the filter screen 18 from becoming clogged, and ensuring the smooth progress of subsequent drying operations.

[0024] Please see Figure 1-2 As shown, two fixing sleeves 25 are fixed to the outer wall of the housing 2 away from the shell 11. Hollow tubes 26 are fixed to the two fixing sleeves 25. Multiple branch tubes 27 are connected to the hollow tubes 26. Each branch tube 27 has a nozzle 28 connected to its other end, and the nozzles 28 are located inside the housing 2. Each branch tube 27 is equipped with a one-way valve. A storage tank 29 is installed on the base 1. A support block 30 is fixed to the top side of the base 1. A pump body 31 is installed on the support block 30. The input port of the pump body 31 is connected to a liquid extraction pipe 32, and the output port of the pump body 31 is connected to a delivery pipe 33. The other end of channel 33 is connected to hollow tube 26. When painting the frame, the frame to be processed is first hung on hook 6. Then, pump body 31 is started, so that the paint in storage tank 29 is drawn out through liquid extraction pipe 32 and flows into hollow tube 26 through delivery pipe 33. Finally, it is sprayed onto the surface of the frame through nozzle 28. At the same time, first motor 3 is started, so that hollow sleeve 4 drives hook 6 and the frame it is hung on to rotate. As the frame rotates, the paint can be evenly sprayed onto the surface of the frame, so that the coating on the surface of the frame is smoother and flatter, thus improving the overall quality of the product.

[0025] A fourth motor 34 is installed on the top of the storage tank 29. The output end of the fourth motor 34 is connected to a stirring shaft 35. Multiple stirring blades 36 are fixed on the stirring shaft 35. A liquid injection pipe 37 is connected to the top of the storage tank 29. During the storage of paint, layering, sedimentation, or clumping may occur. By setting up a stirring mechanism and starting the fourth motor 34, the stirring shaft 35 drives the stirring blades 36 to rotate, thereby stirring the paint in the storage tank 29, making the paint evenly mixed, avoiding layering, sedimentation, or clumping, and ensuring that the paint remains uniform before spraying, thereby improving the spraying quality.

[0026] Working Principle: Since the aforementioned frame painting device lacks a drying mechanism, the frame needs to dry naturally after painting, which typically takes a long time and reduces production efficiency. During natural drying, it is highly susceptible to environmental humidity and temperature factors. Due to uneven distribution of humidity and temperature, natural drying may lead to uneven coating drying, resulting in color differences and inconsistent gloss. Therefore, a frame processing device is proposed to address these issues. After the frame painting is completed, to ensure rapid curing and drying of the coating on the frame surface, a drying mechanism is installed. The second motor 16 is started, causing the fan 17 to rotate. With the cooperation of the spiral heating tube 14, the heated high-temperature gas is directed through the guide pipe 1... 2. The gas flows into the air outlet 10 and is then sprayed onto the frame surface through the air outlet 10. With the cooperation of the first motor 3, the cavity sleeve 4 drives the hook 6 and the frame it is attached to to rotate. As the frame rotates, the high-temperature gas can evenly cover the frame surface, achieving uniform drying of the frame. This allows for rapid and uniform drying of the frame after painting. Compared with natural drying, the drying mechanism greatly shortens the drying time, thereby improving production efficiency. At the same time, by setting up the drying mechanism, the coating can be better cured, avoiding problems such as uneven drying, coating blistering, and cracking that may occur during natural drying. This ensures that the coating quality on the frame surface is more stable and reliable.

[0027] When painting the chassis, the chassis to be processed is first hung on the hook 6. Then, the pump 31 is started, and the paint in the storage tank 29 is drawn out through the extraction pipe 32 and flows into the hollow tube 26 through the delivery pipe 33. Finally, it is sprayed onto the surface of the chassis through the nozzle 28. At the same time, the first motor 3 is started, which causes the hollow sleeve 4 to drive the hook 6 and the chassis it is hanging on to rotate. As the chassis rotates, the paint can be sprayed evenly on the surface of the chassis, making the coating on the chassis surface smoother and flatter, thus improving the overall quality of the product. During the paint storage process, layering, sedimentation, or clumping may occur. By setting up a stirring mechanism and starting the fourth motor 34, the stirring shaft 35 drives the stirring blades 36 to rotate, which can stir the paint in the storage tank 29, making the paint mixed evenly and avoiding layering, sedimentation, or clumping. This ensures that the paint remains in a uniform state before spraying, thereby improving the spraying quality.
