DETAILED DESCRIPTION

[0085] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0086] like Figures 1 to 19 As shown, the metal casting cleaning device of the present invention includes a first cleaning mechanism 1, a conveying mechanism 2, a second cleaning mechanism 3, a camera 4, a positioning member 5, a frame 6 and a third cleaning mechanism 7, which is used for cleaning shaft parts 100.

[0087] like Figures 1 to 4 As shown, the first cleaning mechanism 1 is used to clean one end face and the peripheral surface of the shaft part 100 and remove the casting residue on the surface of the shaft part 100; the conveying mechanism 2 is used to drive the shaft part 100 to perform linear conveyance and / or rotation; the second cleaning mechanism 3 is used to clean the other end face of the shaft part 100; the camera 4 is used to perform appearance inspection on the cleaned shaft part 100;

[0088] As in the above structure, when cleaning the shaft part 100, the first cleaning mechanism 1 is used to clean the peripheral surface and the upper end surface of the shaft part 100 and remove the casting residue on the surface of the shaft part 100;

[0089] After the peripheral surface and the upper end surface of the shaft part 100 are cleaned, the conveying mechanism 2 will convey the shaft part 100 so that the shaft part 100 reaches the cleaning station of the second cleaning mechanism 3;

[0090] At this time, the conveying mechanism 2 stops conveying, changes the action mode, and drives the shaft part 100 to rotate in situ, and the second cleaning mechanism 3 can clean the bottom surface of the shaft part 100;

[0091] After the bottom surface of the shaft part 100 is cleaned, the conveying mechanism 2 drives the shaft part 100 to be conveyed forward a certain distance, so that the shaft part 100 enters the detection station of the camera 4, and the subsequent shaft part 100 continues to enter the cleaning station of the second cleaning mechanism 3. At this time, the conveying mechanism 2 drives at least two shaft parts 100 to rotate, and the first shaft part 100 is photographed and inspected by the camera 4, while the subsequent shaft part 100 is cleaned on the bottom surface by the second cleaning mechanism 3;

[0092] Specifically, the camera 4 adopts an industrial CCD camera, which is used for image acquisition and transmission to the camera for image analysis to achieve detection;

[0093] In this way, the cleaning equipment in this solution can simultaneously realize the cleaning and quality inspection of castings, reduce the tediousness of quality inspection, and ensure production efficiency.

[0094] like Figure 5 As shown, the first cleaning mechanism 1 includes a driving assembly 11 and a first cleaning assembly 12, wherein the driving assembly 11 is used to drive the first cleaning assembly 12 to rotate and revolve around the shaft part 100; the first cleaning assembly 12 is used to clean an end face and a peripheral surface of the shaft part 100, and remove casting residues on the surface of the shaft part 100;

[0095] As shown in the above structure, the first cleaning mechanism 1 is mainly composed of a driving component 11 and a first cleaning component 12, wherein the driving component 11 can drive the first cleaning component 12 to rotate around the circumference of the shaft part 100, and make the first cleaning component 12 rotate, thereby achieving effective cleaning of the shaft part 100.

[0096] like Figure 5 , Figure 6 and Figure 8 As shown, the driving assembly 11 includes a sun gear 111, a planetary gear 112, a ring gear 113, a driving gear 114 and a first cleaning motor 115, wherein the sun gear 111 is coaxially arranged with the shaft part 100 and relatively fixed; the planetary gear 112 is meshed with the sun gear 111, and a plurality of planetary gears 112 are arranged around the sun gear 111, and the first cleaning assembly 12 is arranged on the planetary gear 112; the ring gear 113 has inner teeth 1131 and outer teeth 1132, the inner teeth 1131 are meshed with the planetary gear 112, and the outer teeth 1132 are meshed with the driving gear 114; the first cleaning motor 115 is relatively fixed with the sun gear 111, and the output shaft of the first cleaning motor 115 is connected with the driving gear 114;

[0097] As shown in the above structure, in this drive assembly, the sun gear 111 is fixed, and the planetary gear 112 and the ring gear 113 are rotatable. In this way, when the first cleaning motor 115 drives the driving gear 114 to rotate, the driving gear 114 will drive the ring gear 113 to rotate by engaging with the external teeth 1132, and then the ring gear 113 will drive the planetary gear 112 to rotate. While the planetary gear 112 rotates around the sun gear, it will also rotate on its own, thereby driving the first cleaning assembly 12 to perform a cleaning action.

[0098] like Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the positioning member 5 includes a positioning cylinder 51 and a top cover 52, and the driving assembly 11 also includes a planet carrier 116 and a connecting cylinder 117, wherein the positioning cylinder 51 is a three-level stepped cylinder structure, and the positioning cylinder 51 has a first positioning end face 501, a second positioning end face 502 and a third positioning end face 503 with increasing diameters in sequence; a limiting plate 1133 is provided on the outer circumferential surface of the ring gear 113, the limiting plate 1133 abuts against the first positioning end face 501, and the limiting plate 1133 is slidably matched with the first positioning end face 501; the planetary gear 112 is rotatably connected to the planet carrier 116, the planet carrier 116 abuts against the second positioning end face 502, and the planet carrier 116 is slidably matched with the second positioning end face 502; one end of the connecting cylinder 117 is connected to the sun gear 111, and the other end is connected to the top cover 52, and the top cover 52 is fixedly connected to the third positioning end face 503;

[0099] As described above, in this solution, the positioning member 5 is used to realize the installation of the components in the driving assembly 11. During the specific assembly, the positioning cylinder 51 is fixedly arranged, and then the ring gear 113 is assembled into the positioning cylinder 51, and the limiting plate 1133 of the ring gear 113 is abutted against the first positioning end surface 501 of the positioning cylinder 51, so that the installation of the ring gear 113 is realized;

[0100] Then, the planetary gear 112 is assembled. The planetary gear 112 is integrated on the planetary carrier 116. When assembled, the planetary gear 112 is placed in the positioning cylinder 51. After the planetary carrier 116 abuts against the second positioning end surface 502 of the positioning cylinder 51, the planetary gear 112 is synchronously meshed with the inner teeth 1131 of the ring gear 113.

[0101] Finally, the sun gear 111 is assembled. A through hole is provided in the middle of the planet carrier 116 for the sun gear 111 to be installed. During assembly, the connecting tube 117 on the sun gear 111 passes through the planet carrier 116 and is connected to the top cover 52. Finally, the top cover 52 is connected to the positioning tube 51.

[0102] Thus, in this structure, the positioning cylinder 51, the top cover 52, the connecting cylinder 117 and the sun gear 111 are relatively fixed, and the planetary carrier 116 and the limiting plate 1133 are slidably matched with the positioning cylinder 51, so as to realize the movement of the ring gear 113 and the planetary gear 112; at this time, the first cleaning component 12 can be assembled onto the planetary gear 112.

[0103] Specifically, the positioning tube 51 opens upward, and before removing the top cover 52, the sun gear 111 is supported first, and then the top cover 52 is removed, so that all components of the drive assembly 11 are exposed to the field of vision, which is convenient for inspection and maintenance.

[0104] Specifically, the planetary gear 112 and the ring gear 113 can be axially positioned by their own weight, without the need for additional positioning components, thereby improving the convenience of grouping.

[0105] In some embodiments, a holding member, such as a plane bearing, may be provided on the top cover 52 , so that when the plane bearing holds the planet carrier 116 , the planetary gear 112 may be axially positioned; at the same time, a plane bearing may also be provided between the planet carrier 116 and the limiting plate 1133 of the ring gear 113 .

[0106] In some embodiments, a plane bearing may also be provided between the limiting plate 1133 and the end surface of the planet carrier 116 and the positioning cylinder 51 to reduce friction.

[0107] like Figure 2 and 5 As shown, the first cleaning mechanism 1 further includes a positioning mechanism 13, which includes a carrier 131, a linear drive member 132, a spray pipe 133 and a positioning block 134, wherein the carrier 131 is arranged on the top cover 52; the linear drive member 132 is arranged on the carrier 131; the spray pipe 133 is connected to the movable end of the linear drive member 132, and the spray pipe 133 passes through the drive assembly 11 and the positioning member 5, and the spray pipe 133 is coaxial with the sun gear 111; the positioning block 134 is arranged on one end of the spray pipe 133 away from the linear drive member 132;

[0108] As in the above structure, in order to facilitate water supply and cleaning and positioning of the shaft parts 100, a positioning mechanism 13 is provided;

[0109] The linear drive member 132 of the positioning mechanism 13 is fixed on the top cover 52 through the carrier 131, and the spray pipe 133 directly penetrates the connecting tube 117, the sun gear 111, the planet carrier 116, the ring gear 113 and the positioning tube 51, and the positioning block 134 is arranged at the end of the spray pipe 133;

[0110] In this way, the spray pipe 133 is used for water supply and as a driving rod of the positioning block 134. When positioning the shaft part 100, Figure 5 , Fig.17 and Fig.18 As shown, the linear drive member 132 drives the spray pipe 133 and the positioning block 134 to move downward, and the positioning block 134 is plugged into the inner hole of the shaft part 100, so that it can automatically achieve concentricity with the shaft part 100;

[0111] like Fig.17 As shown, it is the initial placement position of the shaft part 100. Fig.18 As shown, during the alignment process, due to the guiding effect of the positioning block 134, the shaft part 100 will move toward the first cleaning assembly 12 to abut against the surface of the first roller 121 of the first cleaning assembly 12, thereby ensuring the cleaning effect;

[0112] Specifically, the spray pipe 133 can be provided with a water spray hole on the side of the positioning block 134 away from the shaft part 100, and the spray pipe 133 is connected to one end of the linear driving member 132, and the side opening is used for water supply; in this way, after the shaft part 100 is positioned, water is supplied into the spray pipe 133, and the driving assembly 11 is used to drive the first cleaning assembly 12 to perform cleaning;

[0113] In this structure, the positioning mechanism 13 and the driving assembly 11 are integrated, and the two do not interfere with each other, which effectively reduces the space occupation and ensures that the device is compact.

[0114] In some embodiments, the positioning block 134 is configured as a truncated cone structure. When positioning the copper-aluminum casting, the positioning block 134 can be driven by the linear drive member 132 to punch the inner hole of the copper-aluminum casting to form a chamfer, thereby ensuring the stability of the positioning and realizing the chamfering process. The copper-aluminum casting can then be fine-processed.

[0115] like Figure 5 As shown, the first cleaning assembly 12 includes a first roller 121, an end rod 122 and a brush roller 123, wherein the first roller 121 and the brush roller 123 are each connected to a planetary gear 112 through a connecting rod; the end rod 122 is arranged on the circumference of the first roller 121, and a plurality of end rods 122 are arranged in a ring array based on the axis of the first roller 121; the first roller 121 and the end rod 122 are both sleeved with a cleaning sleeve;

[0116] As in the above structure, the first roller 121 is used to connect the planetary gear 112. When connected, the first roller 121 and the planetary gear 112 are positioned relative to each other in the circumferential direction, so that the first roller 121 rotates and revolves along with the planetary gear 112. The first roller 121 is used to clean the circumferential surface of the shaft part 100, and the end rod 122 is used to clean the top surface of the shaft part 100.

[0117] Specifically, the first roller 121 and the end rod 122 are cleaned by using a cleaning sleeve. The cleaning sleeve can be made of cloth, or other materials can be adaptively selected, and can be set in the shape of the first roller 121 and the end rod 122; the brush roller 123 can be a roller, and bristles are arranged on the surface of the roller to achieve cleaning of the casting; some castings will have residual casting sand, burrs, and an oxide layer on the surface. By brushing, the residues on the surface of the casting can be removed and cleaning can be performed at the same time, thereby facilitating subsequent measurement, cutting, polishing and other surface treatment processes.

[0118] In some embodiments, the circumferential surface of the shaft part 100 is used as a rotating surface, but the gate is usually removed by cutting, which will cause cutting residues. Secondary processing of the shaft part 100 to remove the gate cutting residues will increase the working hours. Therefore, the brush roller 123 can be configured as a grinding roller to remove the gate cutting residues by grinding, which is also beneficial for removing other casting residual attachments.

[0119] In such a structure, the end rods 122 are arranged in a circular array, that is, there are intervals between the end rods 122. When the shaft part 100 is positioned by the positioning mechanism 13, as the positioning block 134 is inserted into the shaft part 100, the shaft part 100 is forced to move toward the first roller 121 to squeeze the cleaning sleeve. In order to avoid squeezing the hanging part of the cleaning sleeve on the end rods 122, the displacement direction of the shaft part 100 needs to be kept between the two end rods 122 to prevent squeezing damage.

[0120] The end rod 122 is arranged on the circumference of the first roller 121 close to the planetary gear 112, and the distance between the end rod 122 and the end of the first roller 121 away from the planetary gear 112 is greater than the axial length of the shaft part 100; the first roller 121 and the shaft part 100 have the same diameter, and the number of the array of the end rods 122 is less than six;

[0121] As in the above structure, the bottom surface of the end rod 122 is not flush with the top surface of the shaft part 100, so after the cleaning sleeve is installed, as the first roller 121 rotates, the cleaning sleeve can clean the top surface of the shaft part 100 without the cleaning sleeve being sheared by the end rod 122 and the shaft part 100;

[0122] In this structure, the first roller 121 has the same diameter as the shaft part 100, and the array number of the end rods 122 is controlled to be less than six. In this way, after the shaft part 100 is positioned, even if it is close to the first roller 121, the middle position of the two end rods 122 is ensured to be convenient for the movement of the shaft part 100, and the shaft part 100 will not be squeezed to the hanging part of the cleaning sleeve on the end rod 122.

[0123] This cleaning setting is suitable for shaft parts with a through hole or a positioning hole at one end, and the interface is placed with one end of the hole facing upward to ensure that it can be cleaned using the end rod 122 and is convenient for positioning through the positioning block 134.

[0124] like Fig. 9 and Fig.11As shown, the conveying mechanism 2 includes a rotating shaft 21, a sprocket 22, a chain 23, a flexible belt 24 and a protective shell 25, wherein the first cleaning mechanism 1 and the second cleaning mechanism 3 are both arranged on the frame 6; two rotating shafts 21 are rotatably arranged on the frame 6, and the rotating shaft 21 is provided with a sprocket 22; the chain 23 is meshed with the sprockets 22 on the two rotating shafts 21; the flexible belt 24 is sleeved on the chain 23 and rotates with the chain; the protective shell 25 is arranged on the frame 6, the protective shell 25 surrounds the flexible belt 24, and exposes one side of the flexible belt 24; the camera 4 is arranged on the protective shell 25; the conveying mechanism 2 is relatively arranged with two, so as to clamp the shaft parts 100 through the flexible belt 24;

[0125] As in the above structure, the rotating shaft 21 is connected to a motor to serve as a power source; when working, the rotating shaft 21, the sprocket 22, the chain 23 and the flexible belt 24 in the two conveying mechanisms 2 rotate in opposite directions, so that the two flexible belts 24 clamp the shaft parts 100, and the conveying of the shaft parts 100 can be realized;

[0126] After the shaft parts 100 are transported to the cleaning station of the second cleaning mechanism 3, the two flexible belts 24 rotate in the same direction, so that the shaft parts 100 clamped in the middle will rotate, and the bottom surface of the shaft parts 100 can be cleaned by the second cleaning mechanism 3. After cleaning, the two flexible belts 24 rotate in the opposite direction to send the shaft parts 100 out;

[0127] In this structure, the chain 23 is located inside the flexible belt 24, which can avoid damage to the chain 23 and facilitate replacement of the flexible belt 24;

[0128] In this structure, the protective shell 25 is used to protect the flexible belt 24;

[0129] like Fig.19 As shown, the protective shell 25 includes a side plate 251, an inner plate 252, a ring plate 253, a T-shaped plate 254 and a guide plate 255, wherein the side plate 251 is arranged on the outer side of the flexible belt 24, the inner plate 252 is arranged on the inner side of the flexible belt 24, the ring plate 253 is connected to the side plate 251 and the inner plate 252, the T-shaped plate 254 is connected to the ring plate 253 and the inner plate 252, and one end of the T-shaped plate 254 extends to the inner side of the flexible belt 24, and the guide plate 255 is arranged at one end of the side plate 251;

[0130] As in the above structure, when installing and fixing, the end of the T-shaped plate 254 extending into the flexible belt 24 can be fixed by assembling bolts, so that the fixing components are not exposed, which can ensure a beautiful appearance and reduce the occupied area of ​​the protective shell 25;

[0131] In this structure, the T-shaped plate 254 can also ensure the stability of the overall structure of the protective shell 25. The protective shell 25 exposes one side of the flexible belt 24 to facilitate clamping of shaft parts 100. The guide plates 255 at the ends of the two protective shells 25 are used to guide the shaft parts 100 into the conveying mechanism 2.

[0132] like Fig. 9 As shown, the conveying mechanism 2 is also provided with a push plate 26 and a cylinder 27. Specifically, when arranged, the cylinder body of the cylinder 27 is assembled on the protective shell 25, and the push plate 26 is provided at the movable end. When used, the push plate 26 abuts against the inner surface of the flexible belt 24. Since the protective shell 25 is fixed to the frame 6, when the cylinder 27 is actuated, the push plate 26 will be displaced, thereby achieving the tensioning effect on the flexible belt 24, so that it is suitable for cleaning different shaft parts 100;

[0133] Specifically, the flexible belt 24 is made of a wear-resistant material to reduce sliding wear with the push plate 26;

[0134] In this structure, the chain 23 is embedded in the flexible belt 24, with only the chain hole that engages with the sprocket 22 exposed, so that the flexible belt is released from the push plate 26;

[0135] When the push plate 26 is made of a material with good wear resistance and the surface of the push plate 26 has good lubrication conditions, the push plate 26 can also resist the chain 23 , and the chain 23 does not need to be completely embedded in the flexible belt 24 .

[0136] In some embodiments, the push plate 26 is used to increase the clamping force of the flexible belt 24 on the shaft part 100, and multiple conveying mechanisms 2 can be arranged along the longitudinal direction to accommodate the cleaning of heavy parts.

[0137] like Fig.10 As shown, the conveying mechanism 2 is further provided with a limit frame 28. Specifically, the limit frame 28 can be set as a U-shaped structure. Both ends of the limit frame 28 are connected to a protective shell 25, which is used to carry the camera 4.

[0138] At the same time, one end of the limiting frame 28 is tilted, which facilitates the guidance of the shaft-like parts 100 to ensure that the shaft-like parts 100 are at a suitable height.

[0139] like Fig.11 As shown, the flexible belt 24 has an input end 2401 and an output end 2402, the distance between the two flexible belts 24 at the input end 2401 is greater than the distance at the output end 2402, and the flexible belt 24 has a straight portion 2403 connected to the output end 2402, and the length of the straight portion 2403 is greater than the distance between the cleaning station of the second cleaning mechanism 3 and the detection station of the camera 4;

[0140] As in the above structure, the input end 2401 is a flared structure, which makes it easy to import the shaft parts 100, and the straight portion 2403 can ensure the stable transportation of the shaft parts 100, and when the two flexible belts 24 rotate in the same direction, the shaft parts 100 can achieve stable rotation.

[0141] like Figures 12-14 As shown, the second cleaning mechanism 3 includes a bracket 31, a second roller 32, a water supply pipe 33, a second cleaning motor 34 and a gear set 35, wherein the bracket 31 is arranged on a side of the frame 6 away from the conveying mechanism 2; the second roller 32 is rotatably arranged on the bracket 31, and a cleaning sleeve is sleeved on the second roller 32; the water supply pipe 33 is connected and penetrated with the second roller 32; the second cleaning motor 34 is arranged on the bracket 31, and the output shaft of the second cleaning motor 34 is connected with the water supply pipe 33 through the gear set 35; a through hole 601 is opened on the frame 6 corresponding to the second roller 32;

[0142] As in the above structure, the second cleaning mechanism 3 is used to clean the bottom surface of the shaft part 100. When the cleaning action is performed, the shaft part 100 will be driven by the conveying mechanism 2 so that the bottom surface corresponds to the through hole 601, and the top surface corresponds to the limit frame 28, so that the second roller 32 can clean the bottom surface of the shaft part 100 through the through hole 601. Since the limit frame 28 is above the shaft part 100, the stability during cleaning can be guaranteed to avoid displacement.

[0143] In this structure, the bracket 31 is configured as a box-shaped structure and is buckled onto the through hole 601 from below to achieve a water collection function;

[0144] In specific application, a rotating water supply structure is connected below the water supply pipe 33, such as a water supply assembly with a rotating joint, to transport water into the second roller 32. A through hole is opened on the surface of the second roller 32 so that the water can soak the shaft parts 100.

[0145] Specifically, when the shaft part 100 is a cylindrical structure, the opening width of the through hole 601 is greater than the wall thickness of the shaft part 100; when the shaft part 100 is a solid structure, the opening width of the through hole 601 is greater than the radius of the shaft part 100;

[0146] The above-mentioned structure ensures that the second roller 32 can clean the bottom surface of the shaft part 100, while enabling the frame 6 to support part of the bottom surface of the shaft part 100 to ensure reliable and stable operation.

[0147] like Fig.15 and 16As shown, the present solution provides a third cleaning mechanism 7, which includes a connecting pipe 71, a stopper 72 and a sleeve 73, wherein both ends of the connecting pipe 71 are connected, the stopper 72 is sleeved on the connecting pipe 71 and fixed, the sleeve 73 is sleeved on the connecting pipe 71, the sleeve 73 is a stepped cylindrical structure, and the small diameter section of the sleeve 73 is provided with a through hole communicating with the outside;

[0148] As in the above structure, one end of the sleeve 73 can abut against the end surface of the connecting pipe 71, and the other end can selectively abut against the stop block 72. The sleeve 73 has a certain axial sliding space. When cleaning shaft parts with stepped inner holes, the shaft parts can be sleeved on the sleeve 73. In this way, under the action of water flow, the sleeve 73 will be impacted to move toward the inside of the shaft parts, so that the stepped surface of the sleeve 73 abuts against the stepped surface of the inner hole of the shaft parts 100, thereby ensuring the cleaning effect.

[0149] In this structure, a cleaning sleeve is sleeved on the sleeve 73. After the water flows out through the small diameter section of the sleeve 73, it will flow to the large diameter section along the stepped surface to fully soak the cleaning sleeve, thereby ensuring the cleaning effect.

[0150] The application method of the metal casting cleaning device of the present invention comprises the following steps:

[0151] S1, cleaning the top surface and the peripheral surface of the shaft part 100 by the first cleaning mechanism 1;

[0152] S2, driving the shaft parts 100 to move to the cleaning station of the second cleaning mechanism 3 through the conveying mechanism 2;

[0153] S3, the conveying mechanism 2 drives the shaft part 100 to rotate, and the second cleaning mechanism 3 cleans the bottom surface of the shaft part 100 synchronously;

[0154] S4, after the shaft parts 100 are cleaned, the conveying mechanism 2 drives the shaft parts 100 to move, and when the shaft parts 100 occupy the cleaning position of the second cleaning mechanism 3, the previously cleaned shaft parts 100 are at a certain distance from the second cleaning mechanism 3;

[0155] S5, the conveying mechanism 2 drives the shaft parts 100 to rotate, the second cleaning mechanism 3 cleans the rear shaft parts 100, and the camera 4 performs appearance inspection on the front shaft parts 100.

[0156] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
