7. The polishing method of a polishing apparatus for mechanical equipment according to claim 6, characterized in that: the polishing method comprises the following specific steps:
s1: when the polishing machine is used, firstly, a polishing motor (7), a negative pressure pump (16), a mechanical arm (19), a servo motor (21) and an electric telescopic rod (26) are electrically connected with an electric cabinet (18), a polishing workpiece (14) is placed on a first workbench (13) through the mechanical arm (19), then, an adjusting disc is manually rotated, a main bevel gear (111) can be driven to rotate, four groups of screw rods (113) can be driven to synchronously rotate through the meshing assembly action of the main bevel gear (111) and an auxiliary bevel gear (112), so that the guide sliding plates are driven to synchronously extend outwards or retract inwards through the screwing assembly action of the screw rods (113) and the guide sliding plates (115), the distance between the clamping plates (116) can be adjusted in real time according to the size of a second grinding disc (12), namely, when the adjusting disc is manually rotated in the forward direction, the distance between the four groups of clamping plates (116) can be increased, otherwise, thereby completing the clamping assembly of the second grinding disk (12);
s2: after the electric cabinet (18) starts the grinding motor (7), the grinding motor (7) drives the inner gear ring (5) to rotate, so that two groups of planetary gears (6) are driven to synchronously rotate between the inner gear ring (5) and the outer gear ring (4) through the meshing assembly action between the inner gear ring (5) and the planetary gears (6), the fixing rod (9) drives the first grinding disc (10) to grind and polish the surface of the polished workpiece (14), meanwhile, the buffering telescopic rod (8) can be compressed to provide the compression force of the first grinding disc (10) to the polished workpiece (14), the polishing effect is improved, and meanwhile, the inner gear ring (5) can drive the second grinding disc (12) to rotate when rotating to finish the polishing and grinding treatment of the polished workpiece (14);
s3: in the process that the polishing workpiece (14) is ground by the first grinding disc (10) and the second grinding disc (12), the electric cabinet (18) starts the negative pressure pump (16), so that polishing debris and dust on the polishing workpiece (14) can be sucked into the dust collection box (15) by the negative pressure pump (16) through the air suction pipe (17), and the cleanliness of a polishing working environment is improved;
s4: after a polishing workpiece (14) is ground by a first grinding disc (10) and a second grinding disc (12), an electric cabinet (18) controls a mechanical arm (19) to reset the polishing workpiece (14) on a second workbench (20), then the electric cabinet (18) controls a servo motor (21) to rotate positively, a lead screw (24) is driven to rotate through the speed reduction effect of a speed reducer (22), the slide carriage is driven to move rightwards along the length direction of the lead screw (24) through the screwing assembly effect of the lead screw (24) and the slide carriage (25), so that a sanding roller (28) and a grinding roller (29) can be driven to move rightwards synchronously, when the output end of an electric telescopic rod (26) moves downwards, the sanding roller (28) and the grinding roller (29) can be driven to grind and polish the surface of the polishing workpiece (14), and the surface polishing effect of the surface of the polishing workpiece (14) is improved.
