[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-6 This invention provides a technical solution: a burr removal device for stainless steel castings, comprising a base plate 1 and a support plate 2. Two support plates 2 are symmetrically distributed and fixed to the top surface of the base plate 1. A cross-shaped mounting plate 3 is fixed between the top surfaces of the two support plates 2. A fixing plate 4 is fixed to one side of the top surface of the base plate 1. A robotic arm 5 is rotatably mounted on the surface of the fixing plate 4. A first drive motor 6 is fixedly mounted at the end of the robotic arm 5. A grinding disc 7 is fixed at the output end of the first drive motor 6. The first drive motor 6 drives the grinding disc 7 to rotate, and the position of the grinding disc 7 is adjusted by the robotic arm 5, thereby grinding and removing the burrs at both ends of the tubular casting.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5 A circulating feeding mechanism is set on the bottom surface of the cross-shaped mounting plate 3 and used for feeding tubular castings. The circulating feeding mechanism includes a rotating shaft 8. There are two rotating shafts 8, which are symmetrically distributed and rotatably connected to the bottom surface of the cross-shaped mounting plate 3. A rotating wheel 9 is fixed at the end of the rotating shaft 8. Multiple locking teeth 10 are evenly fixed on the outer surface of the rotating wheel 9. A ring track 11 is rotatably sleeved on the periphery of the two rotating wheels 9. Multiple locking holes 12 are evenly opened on the surface of the ring track 11. The locking teeth 10 engage with the locking holes 12. A second drive motor 19 is fixedly installed on the top surface of the cross-shaped mounting plate 3 and coaxially connected to one of the rotating shafts 8. Connecting seat 13, multiple connecting seats 13 are provided and fixed to the outer surface of the annular track 11 respectively, and mounting rod 14 is provided below the connecting seat 13, and fixing components are provided on the surface of the mounting rod 14. The tubular casting is fixed by a fixing component. Then, the second drive motor 19 drives one of the rotating shafts 8 to rotate, thereby driving one of the rotating wheels 9 to rotate. When the rotating wheel 9 rotates, the locking teeth 10 are engaged in the locking holes 12, thereby driving the annular track 11 to rotate. The other rotating wheel 9 rotates on its own axis as the annular track 11 rotates. When the annular track 11 rotates, it drives the casting in the fixing component to move, thereby facilitating the delivery of the casting to the grinding position (after moving to the grinding position, the annular track 11 stops rotating). Then, the grinding disc 7 grinds the burrs on the casting. After grinding, the annular track 11 continues to rotate and delivers the next casting to be ground to the grinding position, thereby improving the burr removal efficiency of the casting.

[0021] Furthermore, such as Figure 2 , Figure 5 and Figure 6 The fixed components include: Two arc-shaped support plates 15 are provided and fixed to one side of the mounting rod 14. The surface of the mounting rod 14 is provided with a rectangular through hole 16. An arc-shaped clamping plate 17 is slidably connected to the inner wall of the rectangular through hole 16. The arc-shaped clamping plate 17 corresponds to the arc-shaped support plate 15 one by one. The inside of the mounting rod 14 is rotatably connected to the rectangular through hole 16. A third drive motor 31 coaxially connected to the threaded rod 18 is fixedly installed on the bottom surface of the mounting rod 14. The threaded rod 18 is threaded through the end of the arc-shaped clamping plate 17. The workers place the tubular casting to be polished on the arc-shaped support plate 15. Then, the third drive motor 31 drives the threaded rod 18 to rotate, thereby moving the arc-shaped clamping plate 17 downward, which in turn presses and limits the tubular casting, thus maintaining the stability of the casting during deburring and facilitating the placement of the tubular casting, further improving the deburring efficiency of the casting.

[0022] In this embodiment, as Figure 5 and Figure 6 A chip-removing mechanism, located around the circulating feeding mechanism, is used to clean chips from the surface of the casting. The chip-removing mechanism includes: Two first rotating blocks 20 are provided and rotatably connected to the bottom surface of the connecting seat 13. The ends of the first rotating blocks 20 are hinged to second rotating blocks 21. The bottom ends of the two second rotating blocks 21 are rotatably connected to the top surface of the mounting rod 14. A spring 22 is fixed to the top surface of the mounting rod 14, and the top end of the spring 22 is fixed to the bottom surface of the connecting seat 13. A bracket 23 is fixed to the bottom surface of the cross-shaped mounting plate 3. A wave guide rail 24 is fixed to the bottom end of the bracket 23. A roller 25 is rotatably connected to one side of the mounting rod 14, and the roller 25 is rollingly connected to the bottom surface of the wave guide rail 24. After deburring, the tubular casting moves with the rotation of the annular track 11. When the roller 25 moves onto the wave guide 24, the roller 25 rolls up and down on its bottom surface, causing the mounting rod 14 to pull the second rotating block 21, which in turn pulls the first rotating block 20. During this process, the spring 22 provides elastic force, so that the roller 25 can have an upward force after moving down. Thus, the roller 25 can roll on the wave guide 24, thereby causing the mounting rod 14 to shake up and down, which facilitates the shaking off of the debris attached to the tubular casting and brings convenience to the cleaning of debris.

[0023] It is worth noting that, such as Figures 2-4Two symmetrically distributed tie rods 26 are fixed on the top surface of the cross-shaped mounting plate 3. An annular guide rod 27 is provided above the annular track 11. The bottom end of the tie rod 26 is fixed to the top surface of the annular guide rod 27. An annular groove 28 is provided on the inner wall of the annular guide rod 27. Multiple evenly distributed L-shaped fixing blocks 29 are fixed on the inner wall of the annular track 11. A chuck 30 is rotatably connected to the top of the L-shaped fixing block 29. The chuck 30 is rolledly connected to the inner wall of the annular groove 28. When the annular track 11 rotates, it drives the chuck 30 to rotate within the annular groove 28, which serves to limit the movement of the annular track 11 and thus improve the stability of the annular track 11 during operation.

[0024] It should be noted that, as Figure 1 and Figure 2 Two symmetrically distributed T-shaped placement seats 32 are fixed on the top surface of the base plate 1. A collection frame 33 is slidably connected to the inner wall of the T-shaped placement seat 32. The collection frame 33 is located directly below the wave guide rail 24. When the casting is shaken, the debris on its surface falls into the collection frame 33 for collection, which facilitates the centralized treatment of the debris. Two symmetrically distributed L-shaped protective plates 34 are fixed on the top surface of the base plate 1. The robotic arm 5 is located inside the two L-shaped protective plates 34. The L-shaped protective plates 34 block the debris generated during grinding and prevent the debris from splashing. A conveyor belt 35 is fixedly installed on one side of the top surface of the base plate 1. After the debris shaking is completed, the casting continues to move onto the conveyor belt 35. At this time, the limit of the casting is contacted, so that the casting is removed and placed on the conveyor belt 35 to be sent to the next processing position.

[0025] Working principle: First, the operator places the tubular casting to be ground on the arc-shaped support plate 15. Then, the third drive motor 31 drives the threaded rod 18 to rotate, thereby moving the arc-shaped clamping plate 17 downward, thus clamping and limiting the tubular casting. Next, the second drive motor 19 drives one of the rotating shafts 8 to rotate, thereby driving one of the rotating wheels 9 to rotate. When the rotating wheel 9 rotates, the clamping teeth 10 engage in the clamping holes 12, thereby driving the annular track 11 to rotate. The other rotating wheel 9 rotates along with the rotation of the annular track 11. Then, when the annular track 11 rotates, it drives the casting in the fixed assembly to move, thus facilitating the delivery of the casting to the grinding position. Then, the grinding disc 7 grinds the burrs on the casting. After grinding, the annular track 11 continues to rotate. When the roller 25 moves onto the wave guide rail 24, the roller 25 rolls up and down on its bottom surface, causing the mounting rod 14 to pull the second rotating block 21, which in turn pulls the first rotating block 20. During this process, the spring 22 provides elastic force, so that the roller 25 can have an upward force after moving down. Thus, the roller 25 can roll on the wave guide rail 24, thereby driving the mounting rod 14 to shake up and down, which facilitates the shaking off of the debris attached to the tubular casting and makes it easier to clean the debris. The fallen debris is collected by the collection frame 33.

[0026] The first drive motor 6, the second drive motor 19, and the third drive motor 31 can be commercially available and equipped with their own power supplies. This is a mature technology in the field and has been fully disclosed, so it will not be repeated in the specification.
