The automatic coring and core repairing device is mainly composed of a robotic arm and a grinder. The clamp on the robotic arm clamps the sand core from the top, takes the sand core out of the cold core machine, and then places it on the grinder. The grinder on the grinder deburrs the top of the sand core, and then the robotic arm clamps the sand core and places it on the storage table for unloading.

[0004] However, the grinder of the grinder can only deburr the top of the sand core, which causes burrs to still exist on the bottom of the sand core, resulting in the sand core being unable to be fully deburred, affecting the quality of sand core production, and thus affecting the use effect of the automatic coring and core repairing device.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 5 As shown, an automatic coring and repairing device includes: a base plate 1, a supporting platform 4 and a rotating arm 5.

[0028] The two sides of the top of the bottom plate 1 are respectively fixedly connected to the robot arm 2 and the rotating arm 5. The side end of the robot arm 2 is fixedly connected to the connecting shaft 9. The side end of the connecting shaft 9 is fixedly connected to the driving component. The bottom plate 1 is used to provide support for the robot arm 2, the carrying platform 4 and the rotating arm 5. The robot arm 2 is used to control the driving component to take the sand core out of the cold core machine and place it on the carrying platform 4. The driving component can grind the sand core, avoiding the use of a grinder. When the top of the sand core is polished, the driving component takes the sand core out of the carrying platform 4, and the rotating arm 5 turns the sand core over.

[0029] The carrying platform 4 is located between the robot arm 2 and the rotating arm 5 and is fixedly connected to the base plate 1. The top of the carrying platform 4 is connected with a mold 6. The mold 6 can be installed on the top of the carrying platform 4. The mold 6 can be customized according to the shape of the sand core, thereby improving the use efficiency and adaptability of the carrying platform 4. The mold 6 carries and limits the sand core to prevent the sand core from deflecting during deburring.

[0030] The side end of the rotating arm 5 is fixedly connected to a rotating shaft 14, and the side end of the rotating shaft 14 close to the supporting platform 4 is fixedly connected to a rotating clamping plate 15. When the sand core needs to be turned over, the driving component moves the sand core clamp to the rotating clamping plate 15, and the rotating clamping plate 15 clamps the sand core. At this time, the driving component is away from the sand core, and the rotating arm 5 rotates the rotating clamping plate 15 by rotating the rotating shaft 14, thereby achieving the effect of the rotating clamping plate 15 clamping the sand core to turn it over. The driving component clamps the sand core again and places it on the mold 6 on the top of the supporting platform 4 for grinding, thereby achieving sufficient grinding and removing burrs on the sand core. Among them, the use of the rotating arm 5 overcomes the problem that the driving component can only clamp the sand core from the top and cannot perform the flipping operation.

[0031] In some specific embodiments, the driving assembly includes: a control arm 3, a clamping assembly and a grinding assembly. The side end of the control arm 3 is fixedly connected to the connecting shaft 9, and the bottom end of the control arm 3 is fixedly connected to a fixing clamp 21. Slide grooves 16 are respectively provided on both sides of the inside of the control arm 3. The clamping assembly is cooperated with the slide grooves 16 and the grinding assembly is fixedly connected to the top of the control arm 3. When the robot arm 2 controls the control arm 3 to move, the control arm 3 controls the clamping assembly to clamp from the top of the sand core. When the sand core moves to the mold 6, the robot arm 2 rotates the control arm 3 by rotating the connecting shaft 9. At this time, the clamping assembly is located at the top of the control arm 3, and the grinding assembly is located at the bottom of the control arm 3. The robot arm 2 controls the grinding assembly to remove burrs from the surface of the sand core.

[0032] In some specific embodiments, the clamping assembly includes: a slide 19 and a mobile clamp 20, the slide 19 is stuck in the slide 16 and is slidably connected to the inner wall of the slide 16, the bottom end of the slide 19 is fixedly connected to the mobile clamp 20, the inner wall of the slide 16 is fixedly connected to the guide rod 17, the slide 19 is sleeved on the guide rod 17 and is slidably connected to the guide rod 17, the side end of the guide rod 17 is fixedly connected to the circular plate 18, the diameter of the guide rod 17 is smaller than the diameter of the circular plate 18, when the clamping assembly clamps the sand core, the control arm 3 controls the slide 19 to slide in the slide 16, The working principle of the body belongs to the existing technology and will not be elaborated here. The slide 19 drives the mobile clamp 20 to move, and the mobile clamp 20 and the fixed clamp 21 clamp the sand core. On the one hand, the limiting connection between the slide 16 and the slide 19 ensures the stability of the movement of the mobile clamp 20. On the other hand, the guide rod 17 further limits the slide 19. At the same time, the guide rod 17 has a guiding effect on the movement of the slide 19. It should be noted that the circular plate 18 limits the slide 19 to prevent the slide 19 from detaching from the slide 16.

[0033] In some specific embodiments, the grinding assembly includes: a grinder 10, an air duct 11, a connecting plate 12 and a nozzle 13. The grinder 10 is fixedly connected to the top of the control arm 3, and the side end of the grinder 10 is fixedly connected to the connecting plate 12. The air duct 11 is clamped on the inner wall of the connecting plate 12 and fixedly connected to the connecting plate 12. The air duct 11 is fixedly connected to the nozzle 13. When the sand core is deburred, the grinder 10 runs, and the robot arm 2 controls the grinder 10 to grind the sand core by controlling the control arm 3. The airflow is transported through the existing equipment, and the airflow flows along the air duct 11 to the nozzle 13. The nozzle 13 removes the waste chips generated by the grinding of the grinder 10 to prevent the waste chips from floating on the surface of the sand core. Among them, the connecting plate 12 plays a role in fixing the grinder 10.
