Description

Technical Field

[0001] The invention belongs to the technical field of cleaning steel castings, and in particular relates to a cleaning device for steel castings. Background Art

[0002] Steel castings refer to metal parts or components manufactured by casting process. Casting process refers to a manufacturing method in which molten metal is poured into a mold and then cooled and solidified to form parts of the desired shape and size. Metal steel castings are widely used in various industrial fields, including automobiles, aerospace, machinery manufacturing, construction, energy, etc. Different metal materials and shapes can be used for casting according to different application scenarios. Common casting methods include sand casting, metal mold casting, etc.

[0003] Cleaning of steel castings is an important step in the casting process, which aims to remove impurities, residues and contaminants on the surface of steel castings to ensure the quality of steel castings and the smooth progress of subsequent processing. Cleaning methods can be roughly divided into manual cleaning, sandblasting cleaning, chemical cleaning and ultrasonic cleaning. Taking common ultrasonic cleaning as an example, after placing the steel castings in an ultrasonic cleaning machine, the complex internal structure of the steel castings can be cleaned by ultrasound. After these residues are cleaned out, they will float in the liquid in the ultrasonic machine. Due to the complex internal structure of the steel castings, although the residues are no longer adhered to the inside of the steel castings, they will remain in the space inside the steel castings. When taking out the steel castings, the staff also needs to manually shake the steel castings to shake the residues out of the steel castings, which will not only cause a certain burden on the staff, but also affect the cleaning efficiency of the steel castings.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figure 1-Figure 5 As shown, the present embodiment provides a cleaning device for steel castings, including an ultrasonic cleaning machine 1, a cleaning pool 2 is provided inside the ultrasonic cleaning machine 1, a filter plate 3 is installed at the bottom of the cleaning pool 2, the residues cleaned out will fall on the filter plate 3, after the cleaning is completed, the filter plate 3 can be lifted up to quickly clean the inside of the cleaning pool 2, two placement grooves 4 are respectively provided on the side walls at both ends of the cleaning pool 2, a bottom plate 5 is commonly installed in the two opposite placement grooves 4, a center plate 6 is fixedly connected between the two bottom plates 5, a double-axis motor 7 is installed on the top wall of the center plate 6, and a double-axis motor 7 is installed on the top wall of the center plate 6. The two output ends of the motor 7 are respectively fixedly connected with an extension rod 8, and the top wall of the center plate 6 is also fixedly connected with two side plates 9. The side walls of the side plates 9 are provided with through holes 10, and the extension rod 8 passes through the through holes 10. The tops of the two side plates 9 are jointly fixedly connected with a grip rod 11. The height of the side plates 9 is greater than the height of the dual-axis motor 7. The distance between the grip rod 11 and the dual-axis motor 7 is greater than 8 cm. The setting of the grip rod 11 can facilitate the staff to lift the base plate 5 together with the cast steel part, so the distance between the grip rod 11 and the dual-axis motor 7 needs to be convenient for the staff to hold the grip rod 11.

[0026] A protective shell 12 is fixedly connected to the top of the bottom plate 5. A through hole 13 is opened at one end of the protective shell 12 facing the dual-axis motor 7. The end of the extension rod 8 away from the dual-axis motor 7 passes through the through hole 13. A shaking mechanism for shaking the cast steel part is installed in the protective shell 12. The shaking mechanism includes a first oblique rod 14, a second oblique rod 15, a connecting rod 16, a block 17, two side blocks 18, a plurality of support columns 19, a swing rod and two rotating discs 21. The end of the extension rod 8 away from the dual-axis motor 7 passes through the side wall of the protective shell 12, the first oblique rod 14 is fixedly connected to one end of the extension rod 8, the second oblique rod 15 is rotatably connected to the side wall of the protective shell 12 away from the dual-axis motor 7, one end of the connecting rod 16 is fixedly connected to the side wall of the first oblique rod 14, and the other end is fixedly connected to the side wall of the second oblique rod 15. The shapes of the first oblique rod 14 and the second oblique rod 15 can be seen in Figure 2 and Figure 3 Therefore, when the extension rod 8 rotates, the connecting rod 16 can swing around the center point.

[0027] The block 17 is fixedly connected to the side wall of the connecting rod 16, and the two side blocks 18 are rotatably connected to the two ends of the block 17 respectively. The two ends of the block 17 are fixedly connected with rotating blocks 22 respectively. The side walls of the side blocks 18 are provided with rotating holes 23.

[0028] A number of support columns 19 pass through the two side blocks 18 respectively, and the number of support columns 19 is four. Two support columns 19 are fixedly connected to the side walls of each side block 18. The two support columns 19 are respectively located on both sides of the rotating block 22. The support columns 19 will not affect the rotation of the rotating block 22, and at the same time, the rotation of the connecting rod 16 will drive the rotating disk 21 to rotate.

[0029] The two rotating disks 21 are respectively fixedly connected to the two ends of several support columns 19, the swing rod is fixedly connected to the bottom of the rotating disk 21 located below, and the end of the swing rod away from the rotating disk 21 passes through the side wall of the bottom plate 5.

The rotating block 25 is fixedly connected to the top of the lifting rod 26, and the rotating block 25 is rotatably connected to the inner wall of the rotating groove 28. The hook rod 27 is fixedly connected to the end of the lifting rod 26 away from the rotating block 25. The shape of the hook rod 27 is "L" shaped. The material of the hook rod 27 is butadiene rubber. Butadiene rubber has excellent wear resistance and elasticity. Therefore, when it directly contacts the steel casting, it will not cause additional collision damage with the inner wall of the steel casting.

[0030] A rotating mechanism is provided on the side wall of the swing rod, and the rotating mechanism includes a short block 29, a telescopic rod 30 and a moving block 31. The short block 29 is fixedly connected to the side wall of the lifting rod 26, and a groove 32 is provided on the side wall of the short block 29. One end of the telescopic rod 30 is rotatably connected to the inner wall of the groove 32, and the other end of the telescopic rod 30 is rotatably connected to the side wall of the moving block 31. An arc groove 33 is provided on the bottom wall of the bottom plate 5, and the moving block 31 is slidably connected to the inner wall of the arc groove 33. When the lifting rod 26 reciprocates following the rotating disk 21, the telescopic rod 30 can also reciprocate along the arc groove 33 following the moving block 31.

[0031] The working principle of this embodiment is as follows: if the staff wants to put the steel casting into the cleaning tank 2, they first need to lift the lifting rod 26, and the short rod on the side wall of the lifting rod 26 will cause the telescopic rod 30 to shrink, and the hook rod 27 fixedly connected to the lifting rod 26 will be in an open state, and then the staff can hang one end of the steel casting on the hook rod 27 corresponding to the other lifting rod 26, and then release the lifting rod 26. Under the action of the telescopic rod 30, the hook rod 27 returns to the initial position and hangs the other end of the steel casting, and then the staff can put the steel casting together with the bottom plate 5 into the placement groove 4 on the side wall of the cleaning tank 2;

[0032] After the ultrasonic cleaning machine 1 has finished working, the staff can start the dual-axis motor 7, and the extension rod 8 at the output end of the dual-axis motor 7 will drive the first oblique rod 14 to rotate, and the connecting rod 16 fixedly connected to the first oblique rod 14 will drive the second oblique rod 15 to rotate. When the block 17 fixed on the side wall of the connecting rod 16 rotates with the first oblique rod 14, it will also drive the side block 18 and the rotating disk 21 to rotate reciprocatingly, and the rotating rod 24 fixedly connected to the rotating disk 21 will drive the rotating block 25 and the lifting rod 26 to rotate synchronously, and the hook rod 27 fixed at the bottom of the lifting rod 26 will drive the cast steel part to shake together, and then shake the cleaned residue into the cleaning tank 2.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
