Abstract

The invention relates to a double disc round sander. The double disc round sander comprises a rotating shaft, a connecting piece fixed on the rotating shaft, an inner base disc and an outer base disc and further comprises an integration bearing. The integration bearing comprises an inner ring, a middle ring and an outer ring which are all rotatably connected in the radial direction, the middle ring is fixedly connected with the connecting piece, the inner base disc is fixed on the inner ring, and the outer base disc is fixed on the outer ring. According to the double disc round sander, the inner base disc and the outer base disc are connected to the connecting piece by adopting the integration bearing, a plurality of bearings are omitted, heating sources are fewer, parts are fewer, the integration bearing is fixed with the connecting piece through the middle ring, the requirements for the connecting piece are also low, and an assembling process is simple.

Description

technical field [0001] The invention relates to the field of grinding tools, in particular to a double-disk circular sand machine. Background technique [0002] Chinese patent application CN200910024527.7 discloses a traditional double-chassis sander. The double-chassis structure of the double-disc sander includes an inner chassis and an outer chassis that are nested. The double-chassis sander also includes a motor shaft and a connection plate connected to the motor shaft through bearings, and the inner chassis and the outer chassis are connected to the connection plate at the same time. The connecting disc is provided with fan blades and a neck, and a receiving groove is arranged in the neck. In the receiving groove, a pivot pin and the first bearing sleeved on the pivot pin are accommodated here, and the screw passes through the inner chassis and is inserted into the pivot pin in the receiving groove, thereby threading the inner chassis Fastened to the connection plate. ...
