Feeding, the second polishing head floats and feeds along the track along with the corresponding second grinding head.

During grinding and polishing, the dust generated in the grinding and polishing area is extracted in real time by the air extraction and dust collection system 80. Combined with the two actions of blowing air toward the door handle 102 and extraction, the source dust treatment of the processing station is realized, and the dust collection effect is good. , which improves the workshop environment and is beneficial to the physical and mental health of the staff. At the same time, the collected dust can be recycled and used to avoid waste.

The first grinding and polishing unit 50 and the second grinding and polishing unit 60 will return to the origin after finishing the grinding and polishing of a door handle 102; The jig 71 clamps one end of the door handle 102, the side clamping jig is driven by the top cylinder 44 to descend to release the clamping support of the door handle 102, the workpiece clamping jig 71 is driven to descend by the unloading lifting control cylinder 73, and the door is lowered. The handle 102 then descends to disengage from the clamping position of the upper clamping jig 41. Then, the unloading manipulator moves backward to the unloading area. The clamping cylinder 72 controls the workpiece clamping jig 71 to open, and the door handle 102 opens. Fall into the unloading area; here, the unloading area is designed as a blanking guide groove, and the door handle 102 can slide into the storage device after falling into the blanking guide groove; at this point, the entire grinding and polishing operation is completed.
