Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1, as Figure 1-2 shown, the present invention provides a technical solution: a robotic core-repairing manipulator claw, including a mechanical flange 1, a support frame 2, and a pneumatic brush 9. The bottom end of the mechanical flange 1 is provided with a support frame 2, and an empty slot 3 is opened at the bottom end of the support frame 2. A fixed shaft 4 is installed at the bottom end of the empty slot 3 through a bearing, and a claw rotating frame 5 is installed at the bottom end of the fixed shaft 4. A transmission spacing frame 15 is installed on the outer wall of the fixed shaft 4. A transmission mechanism for driving the rotation position of the claw rotating frame 5 is arranged on one side of the support frame 2. The transmission mechanism includes a motor 11 and a main shaft 12. A motor 11 is arranged on one side of the support frame 2, and a main shaft 12 is installed at the output end of the motor 11. A turntable 13 is installed on the outer wall of the main shaft 12, and a transmission shaft 14 adapted to the inner wall of the transmission spacing frame 15 is installed at the bottom end of the turntable 13. By starting the motor 11 to drive the main shaft 12 to rotate, the turntable 13 drives the transmission shaft 14 to rotate the transmission spacing frame 15 by a quarter, so that a 90-degree equal distribution layout is achieved. According to different requirements, it is moved to the corresponding position, and then the pneumatic brush 9 and the core-repairing steel needle 10 at the appropriate position are used to process and clean the sand core.

[0023] Embodiment 2, as Figure 1-4As shown in the figure, the present invention provides a technical solution: a manipulator jaw for robot core repair, including a slot 6 is provided inside the jaw rotating frame 5, and a connecting plug frame 7 is arranged inside the slot 6. An air-driven brush 9 and a core repair steel needle 10 are respectively arranged inside the connecting plug frame 7. An installation mechanism for fixing the positions of the air-driven brush 9 and the core repair steel needle 10 is arranged inside the connecting plug frame 7. The installation mechanism includes a moving slot 16 and a movable rod 17. A moving slot 16 is provided on the inner wall of the connecting plug frame 7, and a movable rod 17 is arranged inside the moving slot 16. A moving frame 20 is installed on one side of the movable rod 17. A threaded slot 18 is provided on one side of the moving slot 16. A threaded rod 19 is installed inside the moving frame 20 through a bearing, and the outer wall of the threaded rod 19 meshes with the inner wall of the threaded slot 18. A spring 24 is sleeved on the outer wall of the movable rod 17, and both sides of the spring 24 are respectively in contact with the side walls of the moving slot 16 and the moving frame 20. An arc-shaped inclined slot 21 is provided on the inner wall of the moving frame 20, and a transmission sliding rod 22 is arranged inside the arc-shaped inclined slot 21. An installation block 23 penetrating through the air-driven brush 9 or the core repair steel needle 10 is sleeved on the outer wall of the transmission sliding rod 22. A threaded layer is provided inside the jaw rotating frame 5, and a positioning screw rod 8 penetrating through the connecting plug frame 7 is arranged inside the threaded layer. By rotating the threaded rod 19, the movable rod 17 at the moving frame 20 is inserted into the moving slot 16, squeezing the spring 24, then the installation block 23 drives the transmission sliding rod 22 to move inside the arc-shaped inclined slot 21, so that the installation block 23 can install and remove the positions of the air-driven brush 9 and the core repair steel needle 10.

[0024] Working principle: First, connect the external power supply. The operator can fixedly install the position of the manipulator flange 1 and the position of the robotic arm through bolts. Then, fix the tools used in the three working conditions of core repair at the position inside the connecting plug frame 7. By rotating the threaded rod 19, the movable rod 17 at the moving frame 20 can be inserted into the moving slot 16, squeezing the spring 24. Then, the installation block 23 drives the transmission sliding rod 22 to move inside the arc-shaped inclined slot 21, so that the installation block 23 can separate the positions of the air-driven brush 9 and the core repair steel needle 10. Then, after inserting the position of the air-driven brush 9 or the core repair steel needle 10 into the connecting plug frame 7, the threaded rod 19 can be rotated to drive the moving frame 20 to move to one side. Further, the transmission sliding rod 22 drives the installation block 23 to insert into the air-driven brush 9 or the core repair steel needle 10 inside the arc-shaped inclined slot 21 for quick installation. The installation and removal of this structure are convenient for replacing different core repair tools. When different tools are needed, the motor 11 can be started to drive the main shaft 12 to rotate. Thus, the turntable 13 drives the transmission shaft 14 to rotate the transmission spacing frame 15 by a quarter, so that a 90-degree equal distribution layout is achieved. According to different requirements, it can be moved to the corresponding position, and then the air-driven brush 9 and the core repair steel needle 10 at the appropriate position are used to process and clean the sand core.

[0025] The operator can separate the rotating positioning screw 8 from the slot 6, and then remove the connecting plug-in frame 7 from the slot 6, which is convenient for installing core repair tools of different sizes.

[0026] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than a limitation on the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
