Description

Technical Field

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

[0002] Anodizing cleaning equipment for automotive parts is a specialized device used in the production process of automotive parts to pre-treat and clean the surfaces of metal components (such as aluminum alloy parts). Its main function is to thoroughly remove oil, scale, debris, and other impurities from the surface of the parts before the anodizing process, ensuring the quality and adhesion of the subsequent anodized film.

[0003] In the field of anodizing cleaning of automotive parts, traditional cleaning equipment typically employs a fixed-volume cleaning tank structure. This fixed-volume design has significant drawbacks: firstly, when the dimensions (such as length and volume) of the parts to be cleaned change, the cleaning tank cannot adaptively adjust its internal space, resulting in the cleaning fluid volume not matching the part's size. For example, when cleaning longer parts, a fixed-volume cleaning tank needs to be filled with a large amount of cleaning fluid to submerge the parts, causing significant waste of cleaning fluid; while when cleaning smaller parts, excessive cleaning fluid not only increases costs but may also lead to unstable cleaning results due to liquid sloshing. Utility Model Content

[0004] The purpose of this invention is to provide an anodizing cleaning device for automotive parts, which solves the problem that the volume of the cleaning tank in the existing anodizing cleaning device is fixed and cannot be adjusted adaptively, resulting in the cleaning fluid dosage not matching the size of the parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anodizing cleaning device for automotive parts includes a cleaning tank, which is composed of a first housing and a second housing, the second housing being slidably inserted into one end of the first housing; a liner, which is disposed inside the cleaning tank for holding cleaning fluid, and the liner adopts a stretchable and deformable structure to adapt to changes in the internal volume of the cleaning tank; and a driving member, which is disposed on the outer surface of the second housing for driving the second housing to move linearly relative to the first housing.

[0007] Preferably, both the first housing and the second housing are groove-shaped structures with an open top and an open end, and their open ends are aligned with each other and slidably fitted together to form an integral cleaning pool with an open top, wherein the second housing is inserted inside the first housing.

[0008] Preferably, the liner includes two connecting plates and a rubber sleeve. The rubber sleeve has a U-shaped groove structure, and its two ends are respectively sealed and fixedly connected to the two connecting plates. The two connecting plates and the rubber sleeve together form a solution cavity with a top opening. The rubber sleeve adopts a corrugated folding structure to achieve expansion and contraction deformation along the axial direction of the cleaning tank.

[0009] Preferably, both connecting plates have an L-shaped bending structure, with their horizontal sections hanging on the edges of the openings at both ends of the cleaning tank and their vertical sections fitting against the inner sidewall of the cleaning tank. A liquid outlet pipe with a valve is installed at the bottom of the connecting plate, and a through hole for the liquid outlet pipe to pass through is provided on the sidewall of the first housing.

[0010] Preferably, the driving component includes a motor and a lead screw. The motor is fixedly installed on the outer side wall of the second housing, and the lead screw is coaxially fixed to the output end of the motor. A threaded hole is provided on the inner wall of the first housing, and the lead screw is threadedly connected to the threaded hole.

[0011] Preferably, a horizontally extending slide rod is fixedly installed at the bottom of the second housing, and a slide groove is provided at the end of the first housing to slide with the slide rod. The slide rod and the slide groove form a guide structure to ensure that the second housing is smoothly inserted into the first housing.

[0012] Preferably, the bottom of the second housing is rotatably connected to two movable wheels via an axle for supporting the second housing.

[0013] This utility model has at least the following beneficial effects:

[0014] An adjustable-volume cleaning tank is employed, consisting of a first housing and a second housing that are slidably fitted together. This design allows for flexible adjustment of the internal space of the cleaning tank according to the size of the automotive parts to be cleaned. When cleaning longer parts, the second housing can be pulled out from the first housing via a drive mechanism, increasing the total length of the cleaning tank; conversely, when cleaning smaller parts, the volume can be shortened, thereby significantly reducing the amount of cleaning fluid used and lowering production costs.

[0027] Reference Figure 1-5 An anodizing cleaning device for automotive parts, comprising a cleaning tank 1,

[0028] The cleaning tank 1 consists of a first shell 11 and a second shell 12. The second shell 12 is slidably inserted into one end of the first shell 11. Both the first shell 11 and the second shell 12 can be made of 304 stainless steel, which has strong corrosion resistance and is suitable for cleaning solutions with strong acids and alkalis. The inner and outer walls of the shells are polished or sanded to reduce sliding resistance and enhance structural strength. The inner liner 2 is located inside the cleaning tank 1 and is used to hold the cleaning solution. The inner liner 2 has a stretchable and deformable structure to adapt to changes in the internal volume of the cleaning tank 1. The driving component 3 is located on the outer surface of the second shell 12 and is used to drive the second shell 12 to move linearly relative to the first shell 11.

[0029] The cleaning tank 1 consists of a first shell 11 and a second shell 12. The second shell 12 can slide at one end of the first shell 11, thus changing the internal volume of the cleaning tank 1. An inner liner 2 is installed inside the cleaning tank 1 to hold the cleaning fluid and employs a stretchable and deformable structure, allowing it to adapt to changes in the internal volume of the cleaning tank 1. A driving component 3 drives the second shell 12 to move linearly relative to the first shell 11, thereby adjusting the volume of the cleaning tank 1. The cleaning tank 1 uses a sliding double-shell structure, allowing the internal volume to be adjusted according to the size of the parts to be cleaned, improving space utilization and significantly reducing the use of cleaning fluid, thus enabling more efficient use of the cleaning fluid.

[0030] Furthermore, both the first housing 11 and the second housing 12 are groove-shaped structures with openings at the top and one end. The opening ends of the two are aligned with each other and slidably connected to form an integral cleaning pool 1 with an opening at the top, wherein the second housing 12 is inserted into the interior of the first housing 11.

[0031] The first housing 11 and the second housing 12 are both groove-shaped structures with one open end. After the open ends are aligned, they are slidably connected. The second housing 12 is completely inserted into the first housing 11 to form an integral container with an open top. The volume can be adjusted by sliding to change the total length.

[0032] Furthermore, the inner liner 2 includes two connecting plates 22 and a rubber sleeve 21. The rubber sleeve 21 has a U-shaped groove structure, with its two ends sealed and fixedly connected to the two connecting plates 22 respectively. The two connecting plates 22 and the rubber sleeve 21 together form a liquid-containing cavity with an open top. The rubber sleeve 21 adopts a corrugated folding structure to achieve expansion and contraction deformation along the axial direction of the cleaning tank 1. The rubber sleeve 21 is made of high-elasticity nitrile rubber or silicone, with a thickness of 3-5mm. The peak height and wave pitch of the corrugated folding structure have been optimized through mechanical simulation to ensure that it is not easily torn during expansion and contraction. The connecting plates 22 are made of stainless steel plate, and the L-shaped bends are rounded to eliminate stress concentration. The horizontal section's hook-like edge is designed with a barbed buckle that precisely matches the groove on the edge of the opening of the cleaning tank 1, ensuring that the inner liner 2 is stable and reliable after installation.

[0033] The rubber sleeve 21 is U-shaped and sealed at both ends by connecting plates 22, forming a solution cavity with an open top. When the volume of the cleaning tank 1 changes, the corrugated structure of the rubber sleeve 21 achieves axial expansion and contraction by folding or unfolding, always maintaining the integrity of the cavity.

[0034] Furthermore, both connecting plates 22 are L-shaped bent structures, with their horizontal sections hanging on the edges of the openings at both ends of the cleaning tank 1 and their vertical sections fitting against the inner sidewall of the cleaning tank 1. A liquid outlet pipe 23 with a valve is installed at the bottom of the connecting plate 22, and a through hole 112 for the liquid outlet pipe 23 to pass through is opened on the sidewall of the first housing 11.

[0035] The horizontal section of the connecting plate 22 hangs on the edges of the openings at both ends of the cleaning tank 1, while the vertical section is tightly attached to the inner wall, fixing the position of the inner liner 2 and facilitating direct replacement of the entire inner liner 2. After cleaning, the valve of the outlet pipe 23 is opened, and the cleaning fluid is discharged through the outlet pipe 23 and the through hole 112 of the first housing 11.

[0036] Furthermore, the drive component 3 includes a motor 32 and a lead screw 31. The motor 32 is fixedly mounted on the outer wall of the second housing 12, and the lead screw 31 is coaxially fixed to the output end of the motor 32. A threaded hole 111 is provided on the inner wall of the first housing 11, and the lead screw 31 is threadedly connected to the threaded hole 111. The motor 32 is a servo motor 32, equipped with a reducer to increase torque and ensure stable drive under different loads. The motor 32 has a protection rating of IP54 or higher, suitable for dusty and humid workshop environments. The motor 32 can be controlled by a PLC or CNC system to achieve automated volume adjustment. A limit switch can be set in the system to automatically cut off power when the second housing 12 slides to its limit position to prevent overload damage.

[0037] The motor 32 drives the lead screw 31 to rotate. The lead screw 31 engages with the threaded hole 111 on the inner wall of the first housing 11, converting the rotational motion into linear movement of the second housing 12, thereby adjusting the volume of the cleaning tank 1.

[0038] Furthermore, a horizontally extending slide rod 5 is fixedly installed at the bottom of the second housing 12, and a slide groove is provided at the end of the first housing 11 to slide in cooperation with the slide rod 5. The slide rod 5 and the slide groove form a guide structure to ensure that the second housing 12 is smoothly inserted into the first housing 11.

[0039] The slide bar 5 can serve to assist in supporting the second housing 12, preventing the second housing 12 from deforming under stress and thus failing to be inserted smoothly.

[0040] Furthermore, the bottom of the second housing 12 is rotatably connected to two movable wheels 4 via axles, which are used to support the second housing 12.

[0041] When the second housing 12 slides, the moving wheel 4 rolls on the ground or support surface, reducing sliding resistance and facilitating the position adjustment of the entire device.

[0042] In summary, in practical applications, cleaning fluid is added to the cleaning tank 1, and then the automotive parts are placed inside the cleaning tank 1 using external hoisting equipment for cleaning. The cleaning tank 1, with its adjustable volume, is composed of a first housing 11 and a second housing 12 that are slidably fitted together. This design allows for flexible adjustment of the internal space of the cleaning tank 1 according to the size of the automotive parts to be cleaned. When cleaning longer parts, the second housing 12 can be pulled out from the first housing 11 via the drive component 3, increasing the total length of the cleaning tank 1; conversely, when cleaning smaller parts, the volume can be shortened, thereby significantly reducing the amount of cleaning fluid used and lowering production costs.
