[0002] In the field of metal processing and manufacturing, aluminum alloys are widely used in multiple industries such as automobiles, aerospace, and electronic devices due to their light weight, high strength, and good corrosion resistance. Aluminum alloy products obtained through the casting process are usually called aluminum alloy castings, such as pump covers, (motor) housing covers, valve bodies, bearing seats, and ring-shaped castings, etc.

[0003] During the production process of aluminum alloy castings, various dirt, oxide scales, casting sands, and other impurities will remain on the surface. These impurities will not only affect the appearance quality of aluminum alloy castings but may also cause a decline in their mechanical properties and accelerate material aging. Therefore, the cleaning of aluminum alloy castings is an important step in the production process.

[0004] Traditional methods for cleaning aluminum alloy castings mainly rely on mechanical cleaning. For example, mechanical conveying equipment is used to move the aluminum alloy castings to be cleaned, so that the aluminum alloy castings pass through mechanical brushing and high-pressure spraying equipment at a uniform speed. Moreover, after the aluminum alloy castings to be cleaned are immersed in the cleaning equipment, they are fished out after a preset time interval to achieve cleaning.

[0005] However, in the above implementation methods, especially when aluminum alloy castings are subjected to high-pressure spraying, multiple aluminum alloy castings are prone to collide under the action of the water column impact force, and the cleaning of complex-shaped or hard-to-reach parts is not thorough.

Detailed implementation manners

[0020] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0021] The aluminum alloy casting processing and cleaning equipment of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0022] As shown Figures 1-9 The aluminum alloy casting processing and cleaning equipment according to the embodiment of the present application may include: a box body 1, a conveying mechanism 2, a plurality of fixture mechanisms 3, a guiding component 4, and a cleaning mechanism 5.

[0023] Among them, a bracket 11 is provided below the box body 1.

[0024] It can be understood that the bracket 11 can reduce the contact area between the box body 1 and the ground, thereby increasing the pressure between the two, and increasing the stability of the device during use.

[0025] It should be noted that the bracket 11 can lift the box body 1, so as to ensure that the fixture mechanism 3 can pass smoothly under the box body 1.

[0026] The conveying mechanism 2 includes a plurality of first reversing gear sets 21, two second reversing gear sets 22, two reversing roller sets 23, a driving component 25, and two toothed belts 24. The conveying mechanism 2 is used to drive the fixture mechanism 3 and the aluminum alloy casting to move.

[0027] Among them, a plurality of first reversing gear sets 21 are respectively connected to the box body 1.

[0028] It should be noted that the number of the plurality of first reversing gear sets 21 described in this embodiment may be 4, 6, 8, etc., which are not specifically limited herein. The plurality of first reversing gear sets 21 are respectively located on both sides of the box body 1.

[0029] Two second reversing gear sets 22 and two reversing roller sets 23 are respectively symmetrically and rotatably arranged on the inner wall of the box body 1, and the two reversing roller sets 23 are located below the two second reversing gear sets 22.

[0030] It can be understood that the two reversing roller sets 23 are located below the two second reversing gear sets 22. Under the action of the two second reversing gear sets 22 and the two reversing roller sets 23, the toothed belt 24 forms a concave structure inside the box body 1, and the fixture mechanism 3 and the aluminum alloy casting move along this concave structure, so as to realize the flipping of the aluminum alloy casting.

[0031] The two toothed belts 24 are respectively wound around the outside of the plurality of first reversing gear sets 21, the two second reversing gear sets 22, and the two reversing roller sets 23, and the toothed belt 24 is meshed and connected with the first reversing gear set 21 and the second reversing gear set 22.

[0032] The driving component 25 is installed on the outer wall of the box body 1, and the driving component 25 is connected to a first reversing gear set 21.

[0033] It should be noted that the drive assembly 25 described in this embodiment may include a drive motor, a worm and worm gear transmission component, two driving wheels, two driven wheels, and two transmission belts. The drive motor is installed on the box body 1. The drive motor is connected to the two driving wheels through the worm and worm gear transmission component. The two driving wheels and the two driven wheels are driven by the two transmission belts. The two driven wheels can drive a first reversing gear set 21 to rotate.

[0034] A plurality of fixture mechanisms 3 are respectively arranged between the two toothed belts 24. The fixture mechanism 3 is used to fix and clamp the aluminum alloy casting to be cleaned. Two guide wheels 43 are symmetrically arranged at the bottom of the fixture mechanism 3.

[0035] The guiding assembly 4 includes two first plate bodies 41 and two first limiting strips 42. The guiding assembly 4 is used to pull the fixture mechanism 3 to cause it to deform.

[0036] Among them, a first through groove 40 is formed on the outer wall of the box body 1. The two first plate bodies 41 are symmetrically arranged on both sides of the first through groove 40. The two first limiting strips 42 are respectively arranged on the corresponding first plate bodies 41. The first limiting strip 42 is arranged in a V-shaped structure. The two guide wheels 43 at the bottom of a fixture mechanism 3 abut against the outer sides of the two first limiting strips 42.

[0037] The cleaning mechanism 5 is arranged on the box body 1.

[0038] In the embodiment of the present application, the external mains power supplies the conveying mechanism 2 and the cleaning mechanism 5 in this device, so as to ensure the normal operation of this device.

[0039] Specifically, after some aluminum alloy castings (such as pump covers) are produced, relevant technicians use external equipment (such as shot blasting machines) to improve their surface roughness, and then use this device to clean the aluminum alloy castings to remove residual impurities (such as metal particles) on the surface of the aluminum alloy castings.

[0040] First, start this device. The conveying mechanism 2 and the cleaning mechanism 5 start to operate. The conveying mechanism 2 drives the fixture mechanism 3 to rotate clockwise at a constant speed. When a fixture mechanism 3 moves close to the guiding assembly 4, the guide wheels 43 at the bottom of the fixture mechanism 3 are aligned with the guiding assembly 4. The fixture mechanism 3 continues to move, and the guide wheels 43 move along the first limiting strips 42. The fixture mechanism 3 is pulled, and the top of the fixture mechanism 3 gradually contracts.

[0041] When the guide wheel 43 moves to the lowest point of the first limit bar 42 in the V-shaped structure, the top of the clamp mechanism 3 shrinks to the minimum, and the relevant technicians can operate external equipment (for example: a robotic arm) to take an aluminum alloy casting to be cleaned and place it on the top of the clamp mechanism 3. After that, the guide wheel 43 continues to move along the first limit bar 42, and the top of the clamp mechanism 3 gradually opens until the clamp mechanism 3 contacts the inner wall of the aluminum alloy casting, thereby clamping and fixing the aluminum alloy casting.

[0042] The conveying mechanism 2 continues to drive the clamping mechanism 3 and the aluminum alloy casting to be cleaned to move. When the aluminum alloy casting to be cleaned moves to the top of the box body 1, under the action of a second reversing gear set 22, the clamping mechanism 3 and the aluminum alloy casting to be cleaned follow the toothed belt 24 to move toward the bottom of the box body 1. At this time, the aluminum alloy casting is flipped 90° compared to before.

[0043] When the aluminum alloy casting to be cleaned moves to the bottom of the box 1, under the action of a reversing roller group 23, the clamping mechanism 3 and the aluminum alloy casting to be cleaned follow the toothed belt 24 to move horizontally at the bottom of the box 1. At this time, the aluminum alloy casting is flipped 90° compared to before.

[0044] When the aluminum alloy casting to be cleaned moves to the bottom of the other side of the box 1, under the action of another reversing roller group 23, the clamping mechanism 3 and the aluminum alloy casting to be cleaned follow the toothed belt 24 to move toward the top of the box 1. At this time, the aluminum alloy casting is flipped 90° compared to before.

[0045] At the same time, the water column sprayed by the cleaning mechanism 5 cleans the aluminum alloy casting. The aluminum alloy casting to be cleaned is carried by the clamping mechanism 3 and continuously changes its angle inside the box 1 to meet the water column sprayed by the cleaning mechanism 5. This not only solves the problem of aluminum alloy castings colliding with each other during the cleaning process, but also in the process of changing the angle of the aluminum alloy casting, on the one hand, it can be thoroughly cleaned, and on the other hand, the cleaning water accumulated inside the aluminum alloy casting can be discharged in time and returned to the box, thereby reducing the loss of cleaning water.

[0046] Then, under the action of another second reversing gear set 22, the clamping mechanism 3 and the cleaned aluminum alloy casting follow the toothed belt 24 to move. At this time, the aluminum alloy casting is flipped 90° compared with before, and the aluminum alloy casting is separated from the interior of the box 1. Relevant technicians can use external equipment to remove the cleaned aluminum alloy casting and repeat the above steps to complete the cleaning of multiple aluminum alloy castings.

[0047] It should be noted that the use of the guide component 4 to pull the clamping mechanism 3 can achieve autonomous clamping of the aluminum alloy casting. In addition, the guide component 4 and the clamping mechanism 3 both use mechanical components to interact with each other, are not affected by the external environment (clean water), and have the advantages of low damage rate and long service life.

[0048] As a possible scenario, in order to further save the use of manpower, an automatically controlled robotic arm (robot) can be used to achieve loading and unloading. Its specific structure has been disclosed in the prior art, so it will not be elaborated in detail here.

[0049] In an embodiment of the present application, as Figures 1-2 shown, the fixture mechanism 3 includes a fixing plate 30, a rod body 31, a plurality of wing plates 32, a plurality of V-shaped rods 33, a plurality of connecting rods 34, a ring body 35, a spring 36, and a base 37.

[0050] Among them, both ends of the fixing plate 30 are respectively connected to the corresponding toothed belts 24. The rod body 31 penetrates through the fixing plate 30 and is slidably connected to the fixing plate 30. A plurality of wing plates 32 are arranged on the outer wall of the rod body 31. The middle parts of the plurality of V-shaped rods 33 are pivotally connected to the corresponding wing plates 32. One ends of the plurality of connecting rods 34 are pivotally connected to one ends of the corresponding V-shaped rods 33. The ring body 35 is sleeved on the outside of the rod body 31. The other ends of the plurality of connecting rods 34 are pivotally connected to the ring body 35. The spring 36 is sleeved on the outside of the rod body 31. The spring 36 is located between the wing plates 32 and the ring body 35. The base 37 is arranged at the end of the rod body 31. The base 37 is located below the fixing plate 30. The guide wheel 43 is rotatably connected to the base 37.

[0051] Specifically, during the process of the fixture mechanism 3 automatically clamping the aluminum alloy casting, first, the guide wheel 43 moves downward along the hypotenuse of the first limiting strip 42. The rod body 31 and the base 37 move downward, the ring body 35 moves upward, the spring 36 is compressed, and the connecting rod 34 drives the V-shaped rod 33 to rotate. The top of the V-shaped rod 33 approaches the rod body 31.

[0052] The external robotic arm places the aluminum alloy casting to be cleaned on the top of the fixture mechanism 3. After the guide wheel 43 passes over the lowest point of the first limiting strip 42, it moves upward. The spring 36 pushes the ring body 35 to move downward. The top of the V-shaped rod 33 abuts against the inner wall of the aluminum alloy casting. Under the action of the elastic potential energy of the spring 36, the top of the V-shaped rod 33 exerts a certain force on the inner wall of the aluminum alloy casting, thereby achieving clamping of the aluminum alloy casting.

[0053] It should be noted that in this embodiment, the mass of the aluminum alloy casting described is relatively light. The top of the V-shaped rod 33 is in point contact with the aluminum alloy casting, and the pressure and force between the two are relatively large. Under the action of the elastic potential energy of the spring 36, the aluminum alloy casting can be stably fixed on the top of the fixture mechanism 3 during the flipping process.

[0054] It should be noted that under normal conditions, under the action of the spring 36, the ring body 35 exerts a force on the fixing plate 30, and the fixture mechanism 3 moves stably.

[0055] After the clamping mechanism 3 clamps the aluminum alloy casting, due to the deformation of the clamping mechanism 3, the ring body 35 changes its position on the rod body 31, that is, the rod body 31 extends a certain distance below the fixed plate 30.

[0056] There is a large frictional force between the rod body 31 and the fixed plate 30. Under the action of the guiding component 4, relative movement can occur between the rod body 31 and the fixed plate 30. After the guide wheel 43 disengages from the guiding component 4, due to the existence of this frictional force, the clamping mechanism 3 will not shake randomly during the flipping process, thereby preventing the aluminum alloy casting from detaching from the clamping mechanism 3 during the cleaning process.

[0057] In the embodiment of the present application, referring to Figure 8 and Figure 9 , this clamping mechanism 3 is suitable for clamping and fixing annular, concave and cylindrical aluminum alloy castings.

[0058] In an embodiment of the present application, as Figure 1 shown, the cleaning mechanism 5 includes a circulating water tank 51, a purification and filtration tank 52 and a plurality of spray rods 53.

[0059] Among them, the circulating water tank 51 and the purification and filtration tank 52 are respectively arranged on the outer wall of the box body 1. The circulating water tank 51 is communicated with the purification and filtration tank 52. A plurality of spray rods 53 are respectively installed inside the box body 1, and the circulating water tank 51 is communicated with the plurality of spray rods 53.

[0060] It should be noted that the circulating water tank 51, the purification and filtration tank 52 and the plurality of spray rods 53 described in this embodiment can be communicated through water pipes, and their specific structures have been disclosed in the prior art, so they will not be elaborated in detail here.

[0061] Specifically, the circulating water tank 51 supplies the cleaning water inside it to the plurality of spray rods 53. After the cleaning water is sprayed out from the spray rods 53, it shoots towards the aluminum alloy casting. The cleaning water converges at the bottom of the box body 1 and then enters the purification and filtration tank 52 for treatment. The treated cleaning water enters the circulating water tank 51 again for use, thus saving the use of water resources and achieving the purpose of green production.

[0062] It should be noted that when the volume of the cleaning water in the circulating water tank 51 is small, an external water source can automatically supplement water resources into the circulating water tank 51.

[0063] In an embodiment of the present application, as Figure 1 , Figure 4 and Figure 5 shown, a cover body 61 is provided above the box body 1, and curtain doors 62 are respectively provided on both sides of the cover body 61.

[0064] It can be understood that setting the cover body 61 and the curtain doors 62 can reduce the splashing of cleaning water to the external environment during the operation of this equipment.

[0065] As a possible situation, in order to further improve the cleaning effect of aluminum alloy castings, a plurality of spray bars 53 can be installed on the inner top wall of the cover body 61, so as to form a multi-directional and all-round three-dimensional cleaning effect inside the box body 1.

[0066] In an embodiment of the present application, as Figure 6 shown, a receiving groove 81 is provided between the box body 1 and a first reversing gear set 21, and an inclined surface 82 is provided on the inner bottom wall of the receiving groove 81.

[0067] It can be understood that after the aluminum alloy casting is cleaned, a part of water droplets adhere to the surface of the aluminum alloy. The conveying mechanism 2 drives the aluminum alloy casting to move, and the water droplets fall into the receiving groove 81. The water droplets can flow back into the box body 1 along the inclined surface 82, which can not only achieve the purpose of saving water resources, but also ensure a comfortable working environment.

[0068] In an embodiment of the present application, as Figure 6 shown, a second through groove 71 is formed in the receiving groove 81, and two second plate bodies 72 are symmetrically provided on both side edges of the second through groove 71. Second limit strips 73 are provided on the second plate bodies 72, and the second plate bodies 72 are arranged obliquely.

[0069] It should be noted that in this embodiment, the position of the second plate body 72 is opposite to the guiding assembly 4.

[0070] Specifically, when the clamping fixture mechanism 3 drives the aluminum alloy casting to move to the second limit strip 73, the guide wheel 43 moves along the second limit strip 73, the spring 36 is compressed, the clamping fixture mechanism 3 deforms, and the clamping fixture mechanism 3 releases the clamping and fixing of the aluminum alloy casting. At the same time, an external robotic arm can remove the cleaned aluminum alloy casting.

[0071] It can be understood that the above implementation manner can avoid the situation that scratches appear on the inner wall of the aluminum alloy casting when the external robotic arm directly removes the aluminum alloy casting, thereby ensuring the quality of the aluminum alloy casting.

[0072] In an embodiment of the present application, as Figure 2 and Figure 7 shown, a plurality of third through grooves 92 are formed in the toothed belt 24. Shaft bodies 91 and fixing members 93 are respectively provided at both ends of the fixing plate 30. The shaft body 91 is pivotally connected to the toothed belt 24, and the fixing member 93 passes through the third through groove 92.

[0073] Specifically, during the process of the toothed belt 24 driving the clamping fixture mechanism 3 to move, when the fixing plate 30 passes by the first reversing gear set 21, the second reversing gear set 22 and the reversing roller set 23, the shaft body 91 rotates by a certain angle, and the fixing member 93 moves inside the third through groove 92, and the fixing plate 30 is not affected.

[0074] It should be noted that due to the arrangement of the third through groove 92, the toothed belt 24 should be made of a rubber material with a relatively thick specification.

[0075] As a possible situation, in order to ensure the service life of the transmission mechanism 2, the toothed belt 24 can also adopt the chain track structure in the prior art. The fixing plate 30 can be directly installed on the chain track structure, and its specific transmission structure has been disclosed in the prior art, so it will not be described in detail here.

[0076] In summary, for the aluminum alloy casting processing and cleaning equipment according to the embodiments of the present application, the guide wheel moves along the first limiting strip, thereby pulling the clamping mechanism to autonomously clamp the aluminum alloy casting to be cleaned after deformation. Under the action of the transmission mechanism, the clamping mechanism carries the aluminum alloy casting to be cleaned and continuously changes the angle inside the box body to meet the water column sprayed by the cleaning mechanism, which not only solves the problem of mutual collision of aluminum alloy castings during the cleaning process, but also during the process of changing the angle of the aluminum alloy castings, on the one hand, the cleaning is thorough, and on the other hand, the cleaning water accumulated inside the aluminum alloy castings can be discharged in time and returned to the box body, thereby reducing the loss of cleaning water.
