Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically a metal cleaning device. Background Technology

[0002] Amid the rapid development of the new energy vehicle industry, the production scale of key components for new energy vehicles continues to expand. As a core component of the electric motor system in new energy vehicles, the resolver bracket plays a crucial role in the stable operation of the vehicle. Currently, many companies are using ductile iron and recycled scrap iron materials to produce resolver brackets. This approach reduces production costs and aligns with the environmental protection concept of resource recycling.

[0003] During the casting process, ductile iron may leave molding sand, release agents, and other impurities on the surface of the resolver bracket. Recycled scrap iron itself may also carry contaminants such as oil and rust. These impurities not only affect the appearance of the resolver bracket, but if they remain on the product surface and enter the motor system, they can cause short circuits, leading to serious safety accidents and impacting the overall performance and safety of new energy vehicles.

[0004] For example, patent CN222001004U discloses a metal processing parts cleaning device, including a cleaning tank, a mounting frame, a sieve box, a shaking mechanism, and a water spray head. The shaking mechanism causes the sieve box to move back and forth, allowing the metal parts to continuously shake within the sieve box, ensuring even contact between the surface and the rinsing water for cleaning.

[0005] When the aforementioned patented cleaning device is used, after repeated use of the sieve box, oil, impurities, and other contaminants may adhere to the surface of the sieve box and the sieve holes during the cleaning process. With increasing usage, this dirt gradually accumulates, affecting not only the filtration efficiency of the sieve box but also potentially causing secondary contamination to subsequent metal parts being cleaned. Furthermore, because the sieve box is slidably connected to the guide rod via a connecting block, and the guide rod is fixedly connected to the mounting frame, this structure makes it difficult to completely separate the sieve box from the equipment after cleaning, increasing the operational difficulty of cleaning the sieve box and hindering the smooth cleaning process. Therefore, it is necessary to provide a metal cleaning device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a metal cleaning device that solves the problem that after repeated use, the surface and screen holes of the screen box of the aforementioned patented cleaning device are easily covered with oil and impurities, and the cleaning operation is difficult due to the connection structure between the screen box and the guide rod.

[0008] The technical solution adopted by this application to solve its technical problem is: a metal cleaning device, including a cleaning tank, which has multiple sets of water spray heads for rinsing metal parts and a water storage pipe for supplying water to the water spray heads; a placement assembly, which is installed on the cleaning tank, which has a sieve box for placing the cleaning tank and a cylinder for extending the sieve box into the cleaning tank, the bottom of the sieve box having a filter groove; and two sets of cleaning assemblies, which are installed on the placement assembly, which have a cleaning brush for cleaning the bottom of the sieve box, a first gear for driving the cleaning brush to rotate, and a first rack for limiting the movement direction of the cleaning brush.

[0009] Furthermore, the placement assembly includes mounting plates installed on both sides of the cleaning tank, the cylinder is mounted on the mounting plates, the telescopic end of the cylinder is fitted with a docking plate, a mounting frame is installed between the two sets of docking plates, the mounting frame is a cuboid structure, guide rails are installed on both sides of the inner wall of the mounting frame, two sets of sliders are slidably mounted on the guide rails, and the sieve box is installed between the four sets of sliders.

[0010] Furthermore, a sealing cover is installed on the mounting frame. The sealing cover has four sets of support columns. The sealing cover is fixedly connected to the mounting frame through the four sets of support columns. The sealing cover is at a certain distance from the opening of the cleaning tank.

[0011] Furthermore, the cleaning assembly includes a concave rod slidably mounted on the bottom of the mounting frame, with both ends of the concave rod slidably connected to the bottom of the mounting frame. The cleaning brush is rotatably mounted between the two ends of the concave rod. The cleaning brush has a rotating shaft, which passes through both ends of the concave rod. The first gear is mounted on the rotating shaft, and the first rack is mounted on the bottom of the mounting frame.

[0012] Furthermore, a second gear is installed on the rotating shaft, a horizontally arranged second slide rail is installed on the inner wall of the cleaning tank, a second sliding block is slidably installed on the second slide rail, and a second rack is installed on the second sliding block.

[0013] Furthermore, a connecting unit is installed at the bottom of the concave rod. The connecting unit includes a fixed rod installed at the bottom of the concave rod. A movable rod is movably connected to one end of the fixed rod. A limiting block is installed at one end of the movable rod. A moving groove is opened on the fixed rod. One end of the movable rod is fixedly connected to the second rack.

[0014] The beneficial effects of this application are: The metal cleaning device provided by this application automatically cleans the screen box filter tank during movement through the cooperation of cleaning brush, gear rack and other structures, avoiding the accumulation of dirt on the surface of the screen box and the screen holes, effectively preventing the screen box filtration effect from being affected and the problem of secondary pollution to subsequent metal parts. At the same time, it can be cleaned without completely separating the screen box from the equipment, reducing the cleaning difficulty.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1-6 As shown, this application provides a metal cleaning device, including a flushing assembly 1, which includes a cleaning tank 11 with an opening at the top and a drain pipe 12 connected to the bottom of the cleaning tank 11. A valve is provided inside the drain pipe 12, which is adapted to discharge water from the cleaning tank 11. Two spraying units are installed inside the cleaning tank 11.

[0028] The spraying unit includes a water storage pipe 13 fixedly installed in the cleaning tank 11. Multiple sets of spray heads 14 are connected to the water storage pipe 13. The spray heads 14 are inclined, and the water storage pipe 13 is suitable for connection with an external water supply device. It should be noted that the multiple sets of spray heads 14 on the two spraying units are inclined in the same direction. When the external water supply device is started, water is delivered to the water storage pipe 13 in the cleaning tank 11. Since the water storage pipe 13 is connected to the multiple sets of inclined spray heads 14, the water flow is divided through the water storage pipe 13 and enters each spray head 14.

[0029] Furthermore, a placement assembly 2 is installed on the cleaning tank 11. The placement assembly 2 includes mounting plates 21 fixedly installed on both sides of the cleaning tank 11, and a cylinder 22 is fixedly installed on the mounting plates 21. A docking plate 23 is fixedly installed on the telescopic end of the cylinder 22. The docking plate 23 is adapted to extend into the cleaning tank 11 along with the telescopic end of the cylinder 22. Two sets of limiting rods 24 are fixedly installed on the docking plate 23. The limiting rods 24 are set through the mounting plate 21 and are adapted to linearly limit the movement of the docking plate 23.

[0030] An installation frame 25 is fixedly installed between the two sets of docking plates 23. The installation frame 25 is a cuboid structure, and guide rails 26 are fixedly installed on both sides of the inner wall of the installation frame 25. Two sets of sliders 27 are slidably installed on the guide rails 26, and a sieve box 28 is fixedly installed between the four sets of sliders 27. The sieve box 28 is used to place metal parts, and the bottom of the sieve box 28 has a filter groove (not shown in the figure).

[0031] In the initial state, the sieve box 28 is located in the cleaning tank 11 near the opening. The staff places the metal parts to be cleaned into the sieve box 28. Because the bottom of the sieve box 28 is equipped with a filter tank, water can flow through during subsequent cleaning to achieve all-round rinsing of the metal parts.

[0032] After the material is loaded, cylinder 22 is activated to move docking plate 23 into the cleaning tank 11. At this time, limiting rod 24 passes through mounting plate 21 and moves synchronously with docking plate 23. Because it restricts the movement of docking plate 23, it ensures that mounting frame 25 and screen box 28 can move smoothly and accurately to the predetermined cleaning position, ensuring the smooth progress of subsequent cleaning work. When screen box 28 reaches the predetermined position, flushing component 1 starts to work. External water supply equipment supplies water to water storage pipe 13. Water flows out at an angle through spray head 14 to flush the metal parts inside screen box 28. Due to the filter tank design at the bottom of screen box 28, water can pass through from the bottom. Combined with the flushing of spray head 14, dirt and impurities on the surface of metal parts are fully removed and dissolved in the water.

[0033] To improve the cleaning effect on metal parts, such as Figures 2-6As shown, a wobbling unit is installed on the side of the mounting frame 25. The wobbling unit includes a corner plate 210 fixedly installed on the side of the mounting frame 25, a motor 211 fixedly installed on the corner plate 210, a circular plate 212 fixedly installed at the output end of the motor 211, a fixed shaft 213 fixedly installed at an eccentric position on the circular plate 212, and a connecting block 215 fixedly installed on the side of the sieve box 28. The connecting block 215 has a connecting rod 216, and a push rod 214 is connected between the connecting rod 216 and the fixed shaft 213. The push rod 214 is movably connected to both the connecting rod 216 and the fixed shaft 213. A spring 217 is fixedly installed on the side of the sieve box 28 away from the connecting block 215. The spring 217 is connected to the inner wall of the mounting frame 25.

[0034] The shaking unit is designed to cause the screen box 28 to shake, allowing the metal parts to continuously change position and angle during the cleaning process. This ensures that the surface of the metal parts makes more thorough contact with the cleaning water, thus improving the cleaning effect. Its working principle is as follows:

[0035] When the motor 211 is started, the output end of the motor 211 begins to rotate. Since the circular plate 212 is fixedly installed at the output end of the motor 211, the circular plate 212 will move in a circular motion along with the output end of the motor 211.

[0036] The fixed shaft 213 on the circular plate 212 is in an eccentric position. As the circular plate 212 moves in a circular motion, the fixed shaft 213 also moves in a circular motion around the center of the circular plate 212. The fixed shaft 213 is movably connected to the push rod 214, and the other end of the push rod 214 is movably connected to the connecting rod 216. The connecting rod 216 is fixed to the connecting block 215, and the connecting block 215 is fixed to the side of the sieve box 28. In this way, the circular motion of the fixed shaft 213 is converted into a pushing and pulling motion on the sieve box 28 through the push rod 214.

[0037] The push and pull of the push rod 214 causes the screen box 28 to slide on the guide rail 26 within the mounting frame 25 via the slider 27. When the push rod 214 pushes the screen box 28, the screen box 28 moves to one side against the tension of the spring 217; when the push rod 214 pulls the screen box 28, the elastic force of the spring 217 assists the screen box 28 to move to the other side. This cycle repeats, causing the screen box 28 to oscillate back and forth within the mounting frame 25.

[0038] Metal parts are placed inside the sieve box 28. The shaking of the sieve box 28 causes the metal parts to tumble and move continuously within the sieve box 28, changing the position and angle of the metal parts. In this way, parts that were originally in the cleaning dead corners or did not have sufficient contact with the cleaning water will be continuously exposed to the water flow sprayed from the spray head 14, so that the surface of the metal parts has uniform and sufficient contact with the cleaning water, thereby effectively improving the cleaning effect of the metal parts;

[0039] A sealing cover 218 is fixedly installed on the mounting frame 25. The sealing cover 218 has four sets of support columns (not shown in the figure). The sealing cover 218 is fixedly connected to the mounting frame 25 through the four sets of support columns. The sealing cover 218 is a certain distance away from the opening of the cleaning tank 11. So when the mounting frame 25 is driven by the cylinder 22 to extend into the designated position in the cleaning tank 11, the sealing cover 218 moves synchronously and covers the cleaning tank 11 to avoid water splashing when the water spray head 14 sprays water to clean the metal parts on the screen box 28.

[0040] To prevent dirt from adhering to the metal parts of the sieve box 28 after use, such as Figures 3-4 As shown, two sets of cleaning components 3 are installed at the bottom of the mounting frame 25. The cleaning component 3 includes a concave rod 31 that is slidably installed at the bottom of the mounting frame 25. The two ends of the concave rod 31 are slidably connected to the bottom of the mounting frame 25. This slidable connection can be understood as follows: a T-shaped groove is fixedly installed at the bottom of the mounting frame 25, and T-shaped blocks that are adapted to slide in the T-shaped groove are fixedly installed at both ends of the concave rod 31.

[0041] A cleaning brush 32 is rotatably mounted between the two ends of the concave rod 31. The cleaning brush 32 has a rotating shaft (not shown in the figure). The cleaning brush 32 passes through the two ends of the concave rod 31 via the rotating shaft, and a first gear 33 is fixedly mounted on the rotating shaft. At the same time, a first rack 34 that meshes with the first gear 33 is fixedly mounted at the bottom of the mounting frame 25. The first gear 33 is adapted to rotate on the first rack 34 to drive the cleaning brush 32 to move along the straight line of the mounting frame 25. At the same time, it can drive the cleaning brush 32 to rotate and clean the filter tank of the sieve box 28.

[0042] In order to drive the first gear 33 to rotate, a second gear 36 is also fixedly installed on the rotating shaft. At the same time, a horizontally arranged second slide rail 37 is fixedly installed on the inner wall of the cleaning tank 11, and a second sliding block 38 is slidably installed on the second slide rail 37. A second rack 35 that meshes with the second gear 36 is fixedly installed on the second sliding block 38. At the same time, in the initial state, since the mounting frame 25 is located in the cleaning tank 11 near the opening, the second gear 36 is simultaneously located on the second rack 35 near the upper end.

[0043] Meanwhile, a connecting unit is installed at the bottom of the concave rod 31. The connecting unit includes a fixed rod 39 fixedly installed at the bottom of the concave rod 31, a movable rod 310 movably connected to one end of the fixed rod 39, and a limiting block 311 fixedly installed at one end of the movable rod 310. A moving groove (not shown in the figure) for the limiting block 311 to slide is provided on the fixed rod 39. One end of the movable rod 310 is fixedly connected to the second rack 35.

[0044] In the initial state, the mounting frame 25 is located inside the cleaning tank 11 near the opening, the concave rod 31 is located at the preset starting position at the bottom of the mounting frame 25 (i.e., near both ends of the mounting frame 25), and the second gear 36 is located on the second rack 35 near the upper end.

[0045] When cylinder 22 pushes mounting frame 25 into the cleaning tank 11, mounting frame 25 is displaced relative to the inner wall of cleaning tank 11, and the second gear 36 fixed on the rotating shaft begins to mesh with the second rack 35. As mounting frame 25 continues to go deeper, the second gear 36 rotates under the action of the second rack 35.

[0046] Since the second gear 36 is fixedly connected to the rotating shaft, its rotation drives the rotating shaft to rotate synchronously. The first gear 33 is also fixed on the rotating shaft and will rotate accordingly. The first gear 33 meshes with the first rack 34 fixed at the bottom of the mounting frame 25. The rotating first gear 33 moves on the first rack 34, driving the cleaning brush 32 to move in a straight line along the bottom of the mounting frame 25. At this time, the movable rod 310 retracts into the fixed rod 39. Since the second rack 35 is connected to the concave rod 31 through the connecting unit, the second rack 35 moves asynchronously with the movement of the concave rod 31, so that the second rack 35 is always meshed with the second gear 36.

[0047] Meanwhile, the cleaning brush 32 rotates around the shaft, cleaning the filter tank at the bottom of the screen box 28 as it moves, effectively removing dirt. After cleaning, the cylinder 22 drives the mounting frame 25 to retract from the cleaning box 11. During retraction, the second gear 36 meshes with the second rack 35 in the opposite direction, causing the shaft and the first gear 33 to rotate in the opposite direction. The cleaning brush 32 then moves and rotates in the opposite direction, returning to its initial position, ready for the next cleaning operation. In this way, during each operation of the cleaning device, the cleaning component 3 can automatically clean the filter tank of the screen box 28, ensuring the cleanliness of the screen box 28 and maintaining the efficient operation of the cleaning device.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
