[0033] The controllable distance burr grinding mechanism 8 includes an auxiliary support plate 9, one end of the auxiliary support plate 9 is fixedly connected to the front edge of the front rotating part 7, the other end of the front rotating part 7 is fixedly provided with a long plate 10, the middle part of the long plate 10 is fixedly provided with a core nut 11, and the core nut 11 is provided with a handle bolt 12, the stud part of the handle bolt 12 and the core nut 11 are threadedly matched, the stud part of the handle bolt 12 passes through the middle part of the long plate 10, the stud part of the handle bolt 12 extends toward the inner side of the electric rotary support device 3, and the extension direction of the stud part of the handle bolt 12 is toward the center of the electric rotary support device 3, the handle bolt 12 The outside of the handle is located on the outside of the electric slewing support device 3, and the end of the stud part of the handle bolt 12 is provided with a bearing seat 13, and a grinding support block 14 is fixedly provided at the bottom of the bearing seat 13. Guide rod bodies 15 are fixedly provided on both sides of the outer side of the grinding support block 14, and the guide rod bodies 15 extend outward. The extension direction of the guide rod body 15 and the extension direction of the stud part of the handle bolt 12 are parallel to each other. The guide rod body 15 passes through the long plate body 10 to play a guiding role, ensuring that the extension direction of the grinding support block 14 and the extension direction of the long plate body 10 are parallel to each other; the inner side of the grinding support block 14 presents an arc shape with an opening facing inward, and a grinding plate body 16 is fixedly provided on the inner side of the grinding support block 14;

[0034] An auxiliary L-shaped plate 17 is fixedly provided on the front side of the grinding support block 14, and the other end of the auxiliary L-shaped plate 17 is rotatably matched with the upper part of the stud part of the handle bolt 12, thereby stabilizing the surface burr grinding equipment 5; an auxiliary nut 18 is fixedly provided on the upper part of the auxiliary L-shaped plate 17, and a clamping limit bolt 19 is provided on the auxiliary nut 18.

[0036] Conveying and positioning of ductile iron castings: With the help of related equipment such as conveying devices, the ductile iron castings are transported to the inside of the surface burr grinding equipment 5, and it is imperative to ensure that the ductile iron castings can accurately reach the designated grinding position.

[0037] Adjusting the distance between the grinding support block 14 and the ductile iron casting: The operator rotates the handle bolt 12. Given the threaded fit between the handle bolt 12 and the core nut 11, the stud portion of the handle bolt 12 moves relative to the core nut 11. Since the end of the stud portion of the handle bolt 12 is connected to the grinding support block 14 via the bearing seat 13, and the guide rods 15 on either side of the grinding support block 14 extend through the elongated plate 10 to provide guidance, when the handle bolt 12 is rotated, the grinding support block 14 moves in the direction of the guide rods 15. This operation controls the distance between the grinding support block 14 and the outer surface of the ductile iron casting until the grinding plate 16 contacts the outer surface of the ductile iron casting. Auxiliary nut 18 on the upper portion of the auxiliary L-shaped plate 17 is equipped with a clamping stop bolt 19. The end of the clamping stop bolt 19 presses against the stop notch 20 at the top of the stud portion of the handle bolt 12, preventing the handle bolt 12 from rotating.

[0038] Ductile Casting Grinding Operation: After the grinding plate 16 contacts the surface of the ductile casting, the controller 2 controls the rotation of the electric slewing support 3. The front rotating portion 7 of the electric slewing support 3 drives the controllable-distance deburring mechanism 8 to rotate, allowing the grinding plate 16 to grind the surface of the ductile casting. During grinding, related equipment such as the conveyor continuously moves the ductile casting to ensure that the entire outer surface of the ductile casting is polished, achieving a comprehensive deburring operation.

[0039] Grinding debris collection: During grinding, the generated grinding chips and debris will fall into the grinding chip collection shell 21 under the action of gravity. The grinding chip collection shell 21 has an upward opening, and the arc-shaped design of its upper opening is conducive to better collection of grinding chips and debris.

[0040] Adjustable grinding:

[0041] The adjustable grinding support block 14 is designed so that the grinding plate 16 can be fine-tuned according to the specific size of the ductile iron casting to achieve the best grinding effect.

[0042] By rotating the handle bolt 12, the operator can easily adjust the distance between the grinding plate 16 and the surface of the ductile iron casting, thereby adapting to ductile iron castings of different sizes and shapes, significantly increasing the flexibility and applicability of the equipment.

[0043] Improve efficiency and precision:

[0044] The continuous rotation of the electric slewing support device 3 drives the grinding plate 16 to grind the ductile iron casting continuously and evenly, which significantly improves the grinding efficiency and reduces the time and labor required for traditional manual grinding.

[0045] The precise adjustment function of the controllable distance burr grinding mechanism 8 ensures that the distance between the grinding plate 16 and the surface of the ductile iron casting is always consistent, thereby ensuring the accuracy and consistency of the grinding and improving the surface quality of the product.

[0046] Strong stability:

[0047] The combined design of the auxiliary L-shaped plate 17 and the clamping limit bolt 19 provides stable support and precise positioning for the grinding support block 14, effectively avoiding equipment deviation due to vibration or grinding force, and ensuring the stability and reliability of the grinding process.

[0048] This stability design further improves the grinding quality and ensures consistent and accurate surface treatment of ductile iron castings.

[0049] Debris Management:

[0050] The design of the grinding debris collection housing 21 effectively collects the debris and grinding debris generated during the grinding process, keeps the working environment clean and tidy, and avoids potential safety risks caused by the debris to operators and equipment.

[0051] The design of the collection shell also facilitates subsequent cleaning and disposal, simplifies maintenance work, complies with environmental protection requirements, and helps achieve green production.

[0052] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
