Referring to fig. 1, a robot sanding apparatus includes:

the polishing device 200 is arranged on the mechanical arm 100, the polishing device 200 comprises a driving device 210 and a polishing disc 230, the driving device 210 is mounted on the mechanical arm 100, and the driving device 210 and the polishing disc 230 are eccentrically connected to drive the polishing disc 230 to eccentrically rotate;

and a worktable provided beside the robot arm 100, the worktable being provided with a placing surface 310.

When the polishing device is used, a workpiece is clamped on the placing surface 310 of the workbench through the clamp, the workbench is arranged, so that the peripheral workpiece has an installation reference plane, the mechanical arm 100 controls the polishing device 200 to polish, the workpiece is convenient to position, and the polishing precision is improved.

Assuming that the motor output shaft is connected with the eccentric shaft 220, when the grinding disc 230 rotates for grinding, the speed of the edge of the grinding disc 230 is the highest due to the fact that the speed of the center of the grinding disc 230 is zero, so that edge burning easily occurs to cause a relatively obvious joint mark to remain between grinding process paths. Under the condition that the polishing disc 230 swings eccentrically, the speed of the center of the polishing disc 230 is not zero, and the speed of the edge of the polishing disc 230 is not always the highest, so that the problem of obvious marks after polishing can be solved.

Specifically, the end of the mechanical arm 100 is provided with a constant force device, which may be of a conventional design in the prior art. Grinding device 200 still includes the motor frame, and the motor frame is installed on the constant force device to grinding device 200 is difficult for vibrating when making to polish. The driving device 210 is fixed on the motor frame.

In some embodiments, the driving device 210 is a motor. The motor is adopted as the driving device 210, so that the output force is large, the cutting force is large during polishing, and the cutting efficiency is high and stable.

The grinding device 200 further comprises an eccentric shaft 220, wherein a first hole is formed in the upper side of the eccentric shaft 220, a second hole 221 is formed in the lower side of the eccentric shaft 220, at least one of the central axis of the first hole and the central axis of the second hole 221 does not coincide with the central axis of the output shaft of the driving device 210, specifically, the central axis of the first hole coincides with the central axis of the output shaft of the driving device 210, and the central axis of the second hole 221 does not coincide with the central axis of the output shaft of the driving device 210.

Be equipped with jump ring 250 and mill connecting shaft 240 in the second hole 221, the inner wall of second hole 221 is equipped with first groove, the downside of first groove is equipped with the spacing groove, jump ring 250 installs spacing groove department, mill connecting shaft 240 with second hole 221 passes through the bearing and connects, the bearing quilt jump ring 250 restricts first inslot. A clamping groove is formed above the grinding disc connecting shaft 240, the clamp spring 250 is limited in the second hole 221 and clamped with the clamping groove, and the lower side of the grinding disc connecting shaft 240 is connected with the grinding disc 230 in a threaded connection mode. The screwing direction of the threaded connection is the same as the torque direction generated by the reaction force applied to the grinding disk 230 during operation, so that the grinding disk 230 does not loosen during grinding. The circlip 250 serves to limit the axial position of the polishing disc 230, preventing the polishing disc 230 from falling. Meanwhile, the clamp spring 250 plays a role of supporting a bearing, and the structure is compact and efficient.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and changes without departing from the spirit of the invention.
