Detailed Implementation
[0029] Example 1, as Figures 1-4 As shown, a single-arm robotic arm includes a base 1. The outer surface of the base 1 has several mounting holes. A support rod 4 is rotatably connected to the top of the base 1. A shaft 5 is rotatably connected to the top of the support rod 4. An arm 6 is rotatably connected to one side of the shaft 5. A rod 7 is rotatably connected to the bottom of the arm 6. A grinding block 8 is rotatably mounted at the bottom of the rod 7. A cleaning device 2 is provided on the outer surface of the rod 7 to facilitate the removal of debris remaining on the surface of the stainless steel workpiece during the grinding process. When using the robotic arm to grind the surface of the stainless steel workpiece, bolts are used to pass through the mounting holes on the outer surface of the base 1 to fix the base 1 in a designated position. The angle and position of the arm 6 and rod 7 are adjusted by controlling the rotation of the support rod 4, shaft 5, and arm 6 through a drive device inside the support rod 4. The grinding block 8 is driven to rotate by the drive device inside the rod 7 to grind the surface of the stainless steel workpiece.
[0030] Reference Figures 1-5 As shown in this embodiment: the cleaning device 2 includes a ring 21, the inner wall of which is fixedly connected to the outer surface of the rod 7. A motor 22 is provided on one side of the rod 7. A first gear 23 is fixedly connected to the output end of the motor 22. A gear ring 24 is rotatably connected to the outer surface of the ring 21. The outer surface of the first gear 23 meshes with the gear ring 24. Three round rods 25 are rotatably connected to the bottom end of the gear ring 24. Several fan blades 27 are fixedly connected to the bottom end of the round rods 25. A second gear 26 is fixedly connected to the top end of the round rods 25. A gear ring 28 is fixedly connected to the bottom end of the ring 21. The outer surface of the second gear 26 meshes with the gear ring 28. When the robotic arm grinds the surface of a stainless steel workpiece, the motor 22 drives the first gear 23 to rotate. The first gear 23 drives the gear ring 24 to rotate on the outer surface of the ring 21. When the gear ring 24 rotates, the second gear 26 at the top of the rod 25 contacts the outer surface of the gear ring 28, which drives the second gear 26 and the rod 25 to rotate. This causes the fan blade 27 at the bottom of the rod 25 to rotate and generate wind, which accelerates the airflow on the surface of the stainless steel workpiece near the grinding block 8. This blows away the grinding debris remaining on the surface of the stainless steel workpiece, minimizing the impact of debris remaining on the surface of the workpiece on the grinding effect of the grinding block 8.
[0031] Reference Figures 2-5As shown, in the embodiment: the bottom end of the tooth ring 24 is fixedly connected with a plurality of U-shaped rods 29, the outer surface of the round rod 25 rotates on the inner wall of the U-shaped rod 29, and the outer surface part rotates on the inner wall of the U-shaped rod 29 when the round rod 25 rotates.

When carrying the mechanical arm, the sliding block 32 can be retracted into the sliding groove 31 to reduce the area of the base 1.

When the sliding block 32 is pushed to be completely retracted into the inside of the sliding groove 31, the magnetic block 34 will be in contact with the outer surface of the base 1 and be magnetically attracted, so as to further fix the position of the sliding block 32 in the sliding groove 31. A recess 35 is arranged on one side of the sliding block 32 and located below the magnetic block 34. By hooking the recess 35 on the outer surface of the sliding block 32 below the magnetic block 34 with the hand, the sliding block 32 can be more conveniently pulled out of the inside of the sliding groove 31.
