The dust collection component 24 is used to collect the dust cleaned inside the casting hole. The dust collection component 24 includes a fan 2401. The fan 2401 is fixedly connected to the two sides of the outside of the collection box 23. The collection box 23 is fixedly connected with a conveying pipe 2403. The other end of the conveying pipe 2403 passes through the interior of the cross plate 10 and is fixedly connected to a dust collecting port 2404. A socket 19 is provided inside the mounting rod 13, and the pin 18 is plugged into the socket 19. A through hole 22 is provided on the right side of the mounting tube 16. The moving rod 20 is slidably connected to the inside of the through hole 22. Positioning rods 25 are fixedly connected to both sides of the outside of the dust collecting port 2404. The bottoms of the two positioning rods 25 are fixedly connected to the two sides of the outside of the cross plate 10. A drawer 2402 is slidably connected to the inside of the collection box 23.
[0026] When cleaning the inside of a cast product's hole, the cast product is first secured to the top of the base plate 5. To ensure the product is securely fixed, the base plate 5 may be equipped with adjustable clamps or fixtures to accommodate cast products of varying shapes and sizes. This securing method not only ensures the stability of the cleaning process but also improves operational safety and efficiency. The electric push rod 11 is then activated, moving the mounting block 12, which is fixed to its output end. The design of the mounting block 12 allows for smooth movement along a guide rail or chute, ensuring no deviation or jamming during the entire process. As the mounting block 12 moves, the internally inserted mounting rod 13 also moves. The mounting rod 13 is connected to a mounting plate 14 fixed to the bottom, on which electric cleaning rollers 15 are mounted on both sides of the top. As the mounting plate 14 moves, the electric cleaning rollers 15 gradually extend into the hole of the cast product. After the electric cleaning roller 15 is completely inserted into the hole, the electric cleaning roller 15 is started. Through its rotation, the electric cleaning roller 15 can effectively remove impurities, dust, and other residues attached to the hole. The speed and cleaning force of the electric cleaning roller 15 can be adjusted according to actual needs to ensure the cleaning effect and avoid damaging the hole wall. When facing holes of different diameters, the electric cleaning roller 15 can be quickly replaced by pulling the pull ring 21. When the pull ring 21 moves, it will drive the movable rod 20 fixed to its outside to move together. The movable rod 20 in turn drives the movable block 17 fixed to its outside to move. As the movable block 17 moves, the fixed pin 18 on the left side also moves. At this time, when the movable block 17 drives the pin 18 to move, it will squeeze the spring 26 mounted on the outside of the movable rod 20, causing the spring 26 to deform under the force. When the pin 18 is released from the inside of the hole 19, the mounting rod 13 and the electric cleaning roller 15 installed below can be removed from the inside of the mounting block 12. To replace the electric cleaning roller 15 with a different size, simply attach the new roller 15 to the mounting rod 13 and insert the mounting rod 13 into the mounting block 12. After releasing the pull ring 21, the spring 26, under the reaction force, reinserts the latch 18 into the socket 19, securing the newly installed electric cleaning roller 15 firmly in place. This allows for efficient cleaning of the holes in cast products and facilitates quick replacement of electric cleaning rollers 15 of different sizes to accommodate holes of varying diameters. This significantly increases the flexibility and applicability of cleaning operations, reduces operation time and difficulty, and improves production efficiency and product quality.This method can more efficiently and reliably clean the holes in the product after casting, meeting diverse cleaning needs. During cleaning, the fan 2401 is started to collect the dust generated by cleaning through the dust collecting port 2404, and then the collected dust is transported to the interior of the collection box 23 through the conveying pipe 2403. When the interior of the collection box 23 is full, the drawer 2402 is removed from the interior of the collection box 23. This facilitates the collection of dust generated when cleaning the holes in the product, prevents dust from spreading in the air, keeps the work area clean and hygienic, and provides a healthier working environment.
[0027] Reference Figure 2 and Figure 3 A cylinder 2 is provided on the left side of the upper part of the bracket 1, and a base plate 5 is installed on the right side of the upper part of the bracket 1. A gear 6 is rotatably connected inside the base plate 5. The upper part of the gear 6 is meshed with the first rack plate 7, and the lower part of the gear 6 is meshed with the second rack plate 8. The upper part of the first rack plate 7 is fixedly connected to the first fixed plate 4, and the upper part of the second rack plate 8 is fixedly connected to the second fixed plate 9. The output end of the cylinder 2 is fixedly connected to the outside of the first fixed plate 4, and a fixing frame 3 is installed on the left side of the upper part of the bracket 1. The cylinder 2 is fixedly connected to the inside of the fixing frame 3.
[0028] To secure the cast product, first place it on top of the base plate 5. Next, activate the pneumatic cylinder 2. Cylinder 2 provides a powerful thrust, ensuring the fixture securely holds the product. The output end of the pneumatic cylinder 2 is fixedly connected to the first fixing plate 4. When activated, the output end propels the first fixing plate 4 smoothly along a predetermined track or guide. This design ensures a linear motion path for the first fixing plate 4, preventing deflection or stalling. As the first fixing plate 4 moves, the first rack plate 7, located below, also moves. The first rack plate 7 is a crucial transmission element, its movement transmitting power through the meshing gear 6. The meshing of the first rack plate 7 with the gear 6 ensures synchronized and stable movement. The rotation of the gear 6 drives the movement of the second rack plate 8 below it. This double-rack design ensures coordinated and stable transmission. As the second rack plate 8 moves, the second fixing plate 9, located above, also moves. The second fixing plate 9 moves in a direction opposite to the first fixing plate 4, providing balanced force when clamping the product. The relative movement of the first and second fixing plates 4, 9, allows the product to be securely clamped between them. This ensures that when cleaning the inside of the hole of the cast product, the product remains stable and does not move or vibrate during the cleaning process. The fixed product prevents uneven cleaning or damage due to vibration or sliding during the cleaning process, ensuring that the cleaning tool maintains stable and even contact with the hole wall, thereby achieving better cleaning results.
[0029] Working principle: When it is necessary to clean the hole of the cast product, first, fix the cast product on the upper part of the bottom plate 5, then start the electric push rod 11, the electric push rod 11 moves with the mounting block 12 fixed at the output end, the mounting block 12 moves with the internally plugged mounting rod 13, the mounting rod 13 moves with the mounting plate 14 fixed at the bottom, the mounting plate 14 moves with the electric cleaning rollers 15 installed on both sides of the lower part, extend the electric cleaning rollers 15 into the hole of the cast product, and then start the electric cleaning rollers 15. The impurities in the hole are cleaned by the rotation of the electric cleaning rollers 15 That is, then, when facing holes of different diameters, by pulling the pull ring 21, the pull ring 21 moves with the external fixed moving rod 20 to move, the moving rod 20 moves with the external fixed moving block 17 to move, the moving block 17 moves with the external left fixed pin 18 to move, when the moving block 17 moves with the pin 18, the spring 26 set on the outside of the moving rod 20 is squeezed, so that the spring 26 is deformed by the force, and then, when the pin 18 is out of the inside of the socket 19, the mounting rod 13 and the electric cleaning roller 15 installed at the bottom are taken out from the inside of the mounting block 12. When installing, replace the adapter The electric cleaning roller 15 only needs to be installed by inserting the mounting rod 13 into the interior of the mounting block 12, and then loosening the pull ring 21. Under the reaction force of the spring 26, the latch 18 is inserted into the interior of the socket 19. This facilitates cleaning the inside of the hole of the cast product and facilitates replacement of electric cleaning rollers 15 of different sizes to adapt to holes of different diameters, thereby improving the flexibility and applicability of the cleaning work. When fixing the cast product, first, place the cast product on the upper part of the bottom plate 5, start the cylinder 2, and the cylinder 2 moves the first fixed plate 4 fixed at the output end. The first fixed plate 4 moves with the first rack plate 7 fixed at the bottom, and the first rack plate 7 moves with the external meshing gear 6 to rotate, and the gear 6 rotates and moves the second rack plate 8 meshing at the bottom, and the second rack plate 8 moves and moves the second fixed plate 9 fixed at the top, so that the first fixed plate 4 and the second fixed plate 9 can be moved relative to each other, so that when cleaning the hole of the cast product, it is convenient to fix the cast product. Fixing the cast product can prevent it from moving or vibrating during the cleaning process, thereby ensuring that the cleaning tool can stably and evenly contact the hole wall to achieve better cleaning effect.
