Description

Technical Field

[0001] The invention mainly relates to the technical field of cleaning aluminum alloy die castings, and in particular to an ultrasonic cleaning device for aluminum alloy die castings. Background Art

[0002] Ultrasonic cleaning utilizes the cavitation, acceleration and straight-forward flow effects of ultrasound in liquid to directly and indirectly affect liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose.

[0003] During the production process of existing aluminum alloy die castings, ultrasonic cleaning devices are required to clean them. However, the following problems may occur during the cleaning process:

[0004] When cleaning oil stains on the surface of aluminum alloy die-castings, it is necessary to add cleaning agents. During the ultrasonic cleaning process, the cleaning agent will produce foam floating on the liquid surface. When the aluminum alloy die-castings are taken out of the cleaning liquid, the foam and some oil stains on the surface will be contaminated on the die-castings again, affecting the cleaning effect. Summary of the invention

[0005] The present invention mainly provides an ultrasonic cleaning device for aluminum alloy die castings to solve the technical problems raised in the above background technology.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] An ultrasonic cleaning device for aluminum alloy die castings, comprising a cleaning tank, an ultrasonic generator is installed inside the cleaning tank, a PLC controller electrically connected to other electrical components is installed on the front side of the cleaning tank, and a cleaning box assembly is installed inside the cleaning tank;

[0008] A foam suction mechanism is installed on both sides of the cleaning pool, and the foam suction mechanism includes two suction pumps installed on both sides of the top of the cleaning pool, a connecting pipe installed at the input end of the suction pump, and a discharge pipe installed at the output end of the suction pump;

[0009] Two groups of floating components are installed inside the cleaning pool, and the floating components include a floating block placed inside the cleaning pool, and a foam block installed at the bottom of the floating block. The floating block is a cavity structure, and foam inlets are provided on both sides of the floating block. A connecting pipe is connected to the top of the floating block, and the connecting pipe is connected to the connecting pipe on the corresponding side.

[0010] Furthermore, in the present invention, the cleaning box assembly includes a mesh-shaped cleaning box and a mesh-shaped box cover installed on the top of the cleaning box.

[0011] Furthermore, in the present invention, sliding grooves are provided on both sides of the top of the cleaning box, and sliding blocks adapted to the sliding grooves are provided on both sides of one end of the box cover, the sliding blocks are located inside the sliding grooves on the corresponding sides, and a handle is installed on the top of the box cover.

[0012] Furthermore, in the present invention, fixed blocks are installed on the top of both sides of the interior of the cleaning tank, and a lifting mechanism is installed inside the cleaning tank. The lifting mechanism includes a ball screw rotatably connected between one of the fixed blocks and the bottom of the cleaning tank, and a driving motor installed on the top of the fixed block and connected to the ball screw, and a connecting rod with a built-in nut slidably installed on the ball screw, and the connecting rod is connected to the cleaning box.

[0013] Furthermore, in the present invention, the lifting mechanism also includes a sliding rod fixedly installed between the other fixed block and the bottom of the cleaning tank, and another connecting rod slidably installed on the sliding rod.

[0014] Furthermore, in the present invention, the two connecting rods are respectively connected to the bottom areas on both sides of the cleaning box.

[0015] Furthermore, in the present invention, threaded button covers are installed at both ends of the connecting pipe, and the threaded button covers are connected to the floating block and the connecting pipe by means of internal and external threads.

[0016] Furthermore, in the present invention, symmetrical L-shaped clamping blocks are installed at the bottom of both ends of both sides of the floating block, and the foam block is located inside the four L-shaped clamping blocks.

[0017] Furthermore, in the present invention, the foam suction mechanism also includes a T-tube connected to the ends of the two discharge pipes, and a collection box connected to one end of the T-tube, and a foam discharge pipe with a valve is installed on one side of the collection box.

[0018] Furthermore, in the present invention, a drain pipe is installed on one side of the cleaning pool, and a water valve is installed on the drain pipe.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] First, the present invention can always float on the cleaning liquid surface through the floating block of the floating assembly. At this time, the foam on the liquid surface and the floating block are at the same height. Then, the suction pump of the foam suction mechanism generates suction force, so that the foam enters the collection box from the foam inlet of the floating block and is finally collected. This can prevent the subsequent aluminum alloy die-casting from contacting with the foam on the liquid surface when it is taken out, resulting in contamination with oil stains and foam again. This method can ensure the cleaning effect of the aluminum alloy die-casting;

[0021] Secondly, the present invention places the aluminum alloy die-casting inside the cleaning box assembly and cooperates with the lifting mechanism to complete the lifting operation. On the one hand, it can avoid the traditional clamping operation that easily causes the aluminum alloy die-casting to fall off or the excessive clamping force of the clamp causes the outer surface of the aluminum alloy to be dented, affecting the quality of the aluminum alloy die-casting. On the other hand, it can prevent a part of the aluminum alloy die-casting from always being in contact with the aluminum alloy die-casting ultrasonic cleaning device. The surface of the aluminum alloy die-casting that is in contact with the aluminum alloy die-casting ultrasonic cleaning device is not easy to be cleaned, which easily causes the problem of cleaning dead corners.

[0033] For examples, please refer to the attached Figure 1-6 , an ultrasonic cleaning device for aluminum alloy die castings, comprising a cleaning tank 10, an ultrasonic generator 20 is installed inside the cleaning tank 10, a PLC controller 70 electrically connected to other electrical components is installed on the front side of the cleaning tank 10, and a cleaning box assembly 50 is installed inside the cleaning tank 10;

[0034] The foam suction mechanism 40 is installed on both sides of the cleaning pool 10, and the foam suction mechanism 40 includes two suction pumps 42 installed on both sides of the top of the cleaning pool 10, a connecting pipe 43 installed at the input end of the suction pump 42, and a discharge pipe 41 installed at the output end of the suction pump 42;

[0035] Two groups of floating components 30 are installed inside the cleaning pool 10, and the floating components 30 include a floating block 31 placed inside the cleaning pool 10, and a foam block 32 installed at the bottom of the floating block 31. The floating block 31 is a cavity structure, and foam inlets 35 are provided on both sides of the floating block 31. A connecting pipe 33 is connected to the top of the floating block 31, and the connecting pipe 33 is connected to the connecting pipe 43 on the corresponding side.

[0036] For details, please refer to the attached Figure 6 The cleaning box assembly 50 includes a mesh cleaning box 51 and a mesh box cover 52 installed on the top of the cleaning box 51;

[0037] It should be noted that, in the present embodiment, when the aluminum alloy die-castings are to be cleaned, the box cover 52 can be opened to place the aluminum alloy die-castings into the cleaning box 51, so that the aluminum alloy die-castings are confined in the cleaning box 51 for cleaning. On the one hand, it can avoid the traditional clamping operation which may easily cause the aluminum alloy die-castings to fall off or the clamping force is too large which may cause the outer surface of the aluminum alloy to be dented, thereby affecting the quality of the aluminum alloy die-castings. On the other hand, it can prevent a part of the aluminum alloy die-castings from being in contact with the aluminum alloy die-casting ultrasonic cleaning device all the time. The surface of the aluminum alloy die-castings in contact with the aluminum alloy die-casting ultrasonic cleaning device is not easy to be cleaned, which may easily cause the problem of cleaning dead corners.

[0038] For details, please refer to the attached Figure 6 The top sides of the cleaning box 51 are provided with sliding grooves 53, and the two sides of one end of the box cover 52 are provided with sliders 54 adapted to the sliding grooves 53. The sliders 54 are located inside the sliding grooves 53 on the corresponding sides, and a handle 55 is installed on the top of the box cover 52;

[0039] It should be noted that, in this embodiment, the slider 54 slides inside the sliding groove 53 to facilitate the box cover 52 to slide open and prevent the box cover 52 from detaching from the cleaning box 51, while the handle 55 facilitates pulling the box cover 52.

[0040] For details, please refer to the attached Figure 1 and attached Figure 5 , the top of both sides of the interior of the cleaning tank 10 are installed with fixed blocks 12, and the interior of the cleaning tank 10 is installed with a lifting mechanism 60, and the lifting mechanism 60 includes a ball screw 61 rotatably connected between one of the fixed blocks 12 and the bottom of the cleaning tank 10, and a driving motor 62 installed on the top of the fixed block 12 and connected to the ball screw 61, and a connecting rod 63 with a built-in nut slidably installed on the ball screw 61, and the connecting rod 63 is connected to the cleaning box 51;

[0041] It should be noted that, in this embodiment, after the aluminum alloy die-casting is placed in the cleaning box 51, the drive motor 62 can be started to rotate the ball screw 61, and then the cleaning box 51 is driven to rise and fall through the connecting rod 63, so that the aluminum alloy die-casting is immersed in the cleaning liquid for ultrasonic cleaning, and rises after cleaning to facilitate the removal of the aluminum alloy die-casting.

[0042] Furthermore, the lifting mechanism 60 further includes a slide bar 64 fixedly mounted between the other fixed block 12 and the bottom of the cleaning tank 10, and another connecting rod 63 slidably mounted on the slide bar 64;

[0043] It should be noted that, in this embodiment, the other side of the cleaning box 51 can be supported by the cooperation of the sliding rod 64 and another connecting rod 63, thereby increasing the stability of the lifting and lowering of the cleaning box 51.

[0044] For details, please refer to the attached Figure 1 and attached Figure 2 , the two connecting rods 63 are respectively connected to the bottom areas on both sides of the cleaning box 51;

[0045] It should be noted that, in the present embodiment, when cleaning is completed and the connecting rod 63 drives the cleaning box 51 to rise to the top, the cleaning box 51 can be completely raised to the top area of ​​the cleaning liquid, thereby making it more convenient to take out the aluminum alloy die-casting.

[0046] For details, please refer to the attached Figure 4 , both ends of the connecting pipe 33 are installed with threaded button covers 34, and the threaded button covers 34 are connected to the floating block 31 and the connecting pipe 43 by internal and external threads;

[0047] It should be noted that, in this embodiment, the threaded button cover 34 and the connecting pipe 33 are rotatably connected. The threaded button cover 34 can be disassembled from the floating block 31 and the connecting pipe 43 by rotating the threaded button cover 34, thereby facilitating the separation of the foam suction mechanism 40 and the floating assembly 30 and facilitating the replacement of the accessories of the two.

[0048] For details, please refer to the attached Figure 4 Symmetrical L-shaped clamps 36 are installed at the bottom of both ends of the floating block 31, and the foam block 32 is located inside the four L-shaped clamps 36;

[0049] It should be noted that, in this embodiment, the connecting pipe 33 is a plastic hose, and the floating block 31 is a plastic shell block, so as to ensure that the buoyancy of the foam block 32 can hold up the floating block 31. The foam block 32 is easily damaged. After damage, it can be easily replaced by pulling out the foam block 32.

[0050] For details, please refer to the attached Figure 3 The foam suction mechanism 40 further includes a T-tube 44 connected to the ends of the two discharge pipes 41, and a collection box 45 connected to one end of the T-tube 44, and a foam discharge pipe 46 with a valve is installed on one side of the collection box 45;

[0051] It should be noted that, in this embodiment, the foam and water in the two drain pipes 41 can be collected by the T-tube 44 and the collection box 45 and stored inside the collection box 45 for subsequent unified processing, which can be conveniently processed by opening the foam drain pipe 46 later.

[0052] For details, please refer to the attached Figure 2A drain pipe 11 is installed on one side of the cleaning tank 10, and a water valve is installed on the drain pipe 11;

[0053] It should be noted that, in this embodiment, the cleaning liquid in the cleaning pool 10 can be easily discharged by opening the water valve on the drain pipe 11 .

[0054] The specific operation mode of the present invention is as follows:

[0055] When the aluminum alloy die casting needs to be cleaned, first slide the box cover 52 to open the cleaning box 51, then put the aluminum alloy die casting into the cleaning box 51, then close the box cover 52, then start the ultrasonic generator 20 and the drive motor 62, the ball screw 61 rotates, and then drives the cleaning box 51 to descend through the connecting rod 63, so that the aluminum alloy die casting is immersed in the cleaning liquid for ultrasonic cleaning;

[0056] Before the cleaning is completed, the PLC controller 70 starts the suction pump 42. At this time, the buoyancy of the foam block 32 will keep the floating block 31 always floating on the liquid surface, and the foam is also on the liquid surface. The foam inlets 35 on both sides of the floating block 31 generate suction, so that the foam is sucked into the floating block 31, and finally enters the collection box 45 through the connecting pipe 43, the discharge pipe 41 and the T-tube 44. When most of the foam has been processed, the drive motor 62 is started again to make the cleaning box 51 rise, and finally the box cover 52 is opened to take out the aluminum alloy die-casting. Finally, the water valve on the drain pipe 11 can be opened to conveniently discharge the cleaning liquid in the cleaning pool 10, and the foam discharge pipe 46 is opened to discharge the foam in the collection box 45.

[0057] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
