Description

Technical Field

[0001] The utility model relates to the technical field of polishing processing equipment, in particular to a robot polishing device. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. Among them, mechanical polishing usually uses a polishing wheel as a polishing tool. During the polishing operation, the manipulator clamps the workpiece and presses it against the high-speed rotating polishing wheel, so that the abrasive rolls and slightly cuts the surface of the workpiece, thereby obtaining a bright processed surface, and its surface roughness can generally reach Ra0.63 to 0.01 microns. However, the existing manipulator can only clamp one workpiece at a time for grinding, and during the grinding process, it is necessary to replace polishing wheels of different mesh sizes to achieve a better polishing effect, which leads to a low efficiency of the polishing process and is not conducive to batch processing of workpieces. A new type of manipulator is needed to solve the above problems. Utility Model Content

The rotating shaft mechanism includes a swing motor 11, which is installed at the top of the crossbeam 3. The gear at the output end of the swing motor 11 extends into the inner cavity of the crossbeam 3 and meshes with the gear on the shaft body of the steering shaft 4. The two ends of the steering shaft 4 are rotatably connected to the inner cavity of the crossbeam 3. The crossbeam 3 is provided with a movable groove 301 that cooperates with the cantilever 5. The output end of the built-in rotating motor 6 of the cantilever 5 is connected to the electromagnetic suction cup 7. Each electromagnetic suction cup 7 corresponds to the position of each column of grinding groups in the grinding mechanism. A number of grinding belts 8 are distributed in the grinding group in a decreasing order from bottom to top.

[0017] In this embodiment, the grinding mechanism includes a grinding frame 9, which is installed at one end of the longitudinal electric rail. Three pairs of guard plates 901 are provided on the top surface of the grinding frame 9. The grinding belts 8 of the corresponding grinding groups are sandwiched between the same pairs of guard plates 901. The grinding meshes of the grinding belts 8 of each level are different.
