Revolving multi- axis polishing apparatus

Abstract

A revolving multi-axis polishing apparatus includes a main vertical column in a machine body, an abrasive container set, and a multi-axis transmission device. The abrasive container adjacent to the main vertical column is filled with abrasive materials. The multi-axis transmission device, is movably mounted onto the main vertical column containing a moving mechanism, includes a primary driving module, a transmission housing, a rotation assembly, a plurality of secondary driving modules, and a plurality of shaft assemblies. The transmission housing is connected to the primary driving module. The rotation assembly is rotatably mounted inside the transmission housing. The secondary driving modules mounted onto the transmission housing are transmissively connected individually to the rotation assembly. The shaft assemblies rotatably locked onto the rotating assembly are driven to rotate and revolve synchronously to achieve polishing actions.

What is claimed is: 
     
         1 . A revolving multi-axis polishing apparatus, comprising:
 a machine body containing a main vertical column;   an abrasive container set, located adjacent to the main vertical column, filled with abrasive materials; and   a multi-axis transmission device, mounted movably to the main vertical column for sliding reciprocally in a direction toward or away from the abrasive container set, including:
 a primary driving module, having a driving shaft; 
 a transmission housing, connected to the primary driving module, the driving shaft being extended into the transmission housing; 
 a rotation assembly, rotatably mounted inside the transmission housing; 
   a plurality of secondary driving modules, mounted onto the transmission housing, transmissively connected individually to the rotation assembly; and   a plurality of shaft assemblies, rotatably mounted to the rotation assembly, each of the plurality of shaft assemblies being transmissively linked to the driving shaft and being able to mount at least one workpiece;   wherein the plurality of shaft assemblies are driven to rotate synchronously by the primary driving module; and are driven to revolve synchronously by the plurality of secondary driving modules and the rotation assembly.   
     
     
         2 . The revolving multi-axis polishing apparatus of  claim 1 , wherein the rotation assembly further has an outer transmissive ring gear transmissively connected to the plurality of secondary driving modules. 
     
     
         3 . The revolving multi-axis polishing apparatus of  claim 1 , wherein the plurality of secondary driving modules are positioned symmetrically to two opposing sides of the rotation assembly with respect to a rotation axis of the rotation assembly. 
     
     
         4 . The revolving multi-axis polishing apparatus of  claim 1 , wherein each of the plurality of shaft assemblies includes:
 a shaft sub-assembly;   a gear disk, firmly mounted onto the shaft sub-assembly; and   a transmission member, transmissively linking the gear disk to the primary driving module.   
     
     
         5 . The revolving multi-axis polishing apparatus of  claim 4 , wherein the primary driving module further includes a plurality of outer ring gears, each of the plurality of outer ring gears sleeves firmly onto the driving shaft, and each of the plurality of outer ring gears is transmissively linked to the gear disk of the respective one of the plurality of shaft assemblies via the transmission member of the respective one of the plurality of shaft assemblies. 
     
     
         6 . The revolving multi-axis polishing apparatus of  claim 4 , wherein the shaft sub-assembly includes a shaft body and an engagement member, while the gear disk is fixedly mounted onto the shaft body, the engagement member is rigidly connected to a lower end of the shaft body; and the engagement member is for mounting a workpiece-connecting arm for further mounting at least one workpiece. 
     
     
         7 . The revolving multi-axis polishing apparatus of  claim 1 , wherein the primary driving module is a servo motor assembly in a CNC (Computerized numerical controlled) machine. 
     
     
         8 . The revolving multi-axis polishing apparatus of  claim 1 , wherein each of the plurality of secondary driving modules is a servo motor assembly in a CNC (Computerized numerical controlled) machine.
