The invention discloses an eccentric polishing mechanism. The eccentric polishing mechanism comprises a driving mechanism, a middle connecting piece and a polishing disc, wherein the driving mechanism is provided with an output shaft; the output shaft is connected with the middle connecting piece through a bond; the polishing disc is connected with a polishing shaft, the polishing shaft can be rotatably mounted on the middle connecting piece, and the polishing shaft and the output shaft are arranged eccentrically. The output shaft of the eccentric polishing mechanism is connected with the middle connecting piece through the bond; the output shaft is eccentrically and indirectly connected with the output shaft through the middle connecting piece; moment only transmits between the output shaft and the middle connecting piece, movement by twisting in a polishing process cannot be produced because the influence on force produced by polishing of the polishing disc can be avoided, and polishing line marks caused by polishing can be effectively cleared; and by adopting a gas sealing structure, entrance of polishing solutions, water and the like into an eccentric base inner cavity can be prevented, a protection effect on bearings and motors can be achieved, and the problem that the sealing effect is reduced along the time prolonging because abrasion occurs in a conventional contact type dynamic sealing manner is avoided.
Description
technical field [0001] The invention relates to the technical field of material surface polishing, in particular to an eccentric polishing mechanism. Background technique [0002] With the improvement of people's living standards, the material demand is also getting higher and higher. For example, there are also high requirements for the surface of the object, so the surface of the object needs to be polished. The traditional polishing method is to use the polishing head of the polishing machine to rotate at a high speed (about 3000 rpm) to polish the object in a rough and fine manner (different polishing consumables). [0003] After the object is polished by the concentric polishing disc, the polishing texture marks of the polishing disc will be left. Later, an eccentric polishing disc was adopted, and the eccentric mechanism will produce rubbing motion during the polishing process, which can effectively remove the polishing traces left by polishing, such as figure 1 sho...
