Description

Technical Field

[0001] The utility model belongs to the technical field of polishing technology, and particularly relates to a multi-turntable linkage mechanism. Background Art

[0002] Polishing is the modification of the workpiece surface using polishing tools and abrasive particles or other polishing media. The common polishing method is to use a high-speed rotating polishing wheel to press against the workpiece, so that the abrasive rolls and slightly cuts the workpiece surface, thereby obtaining a bright processed surface. However, existing polishing equipment faces several key problems: 1) In order to meet different polishing requirements, the polishing equipment needs to be stopped and adjusted. Each stop adjustment will consume manpower and time, reducing production efficiency; 2) Different workpieces require different polishing strengths and polishing rotation directions. Existing polishing equipment is difficult to adjust the polishing strength and polishing rotation direction in real time; 3) The equipment utilization rate is low. Traditional polishing equipment cannot fully utilize the similarities between multiple products, resulting in the equipment being idle for some time, causing a waste of resources.

A driving wheel 2 is fixed on the rotating shaft 1, and the teeth of the driving wheel 2 mesh with the teeth of the planetary gears 3; a through hole is provided in the center of the large gear 4, and the lower end of the rotating shaft 1 passes through the through hole of the large gear 4 without contact, and is connected to the driving main wheel 8 at the lower end of the rotating shaft 1; the driving gear 5 meshes with the large gear 4.

[0018] The driving gear 5 and the driving main wheel 8 are each equipped with an independent driving motor system (including a motor, a power supply, a controller, etc.).

[0019] Working principle:
