10. An unmanned automotive parts grinding apparatus according to any one of claims 1 to 9, deriving a grinding method for an unmanned automotive parts grinding apparatus, characterized in that: the polishing method comprises the following steps:

firstly, when the device is used for polishing a part, adjusting bolts (804) arranged on two first fixing sleeves (805) and a second fixing sleeve (812) according to the size of the part, adjusting the two first fixing sleeves (805) and the second fixing sleeve (812) to proper positions, fastening three adjusting bolts (804) after adjustment, fixing the two first fixing sleeves (805) and the second fixing sleeves (812) on a first rotating shaft (803), starting two first electric push rods (807) arranged on two connecting blocks (808), and fixing the part through two pressure plates (810) arranged on the output ends of the two first electric push rods (807);

secondly, the parts are stably clamped and fixed, then pressure data received by the two pressure plates (810) after the parts are stably clamped are detected through two pressure sensors (809) installed inside the two pressure plates (810), the data are transmitted to a single chip microcomputer (22) through electric signals, proper clamping force is obtained through analysis and record storage of the single chip microcomputer (22), the fixed parts are tightly attached to an electromagnetic suction cup (811) installed at one end of a small electric telescopic rod (813) by starting the small electric telescopic rod (813) installed at one side of a second fixed sleeve (812), the electromagnetic suction cup (811) is controlled to be started through the single chip microcomputer (22), and metal parts are adsorbed and reinforced;

thirdly, after polishing is started, starting two linear modules (5) arranged on fixed long plates (4) arranged at two sides of a protective cover (2), controlling a baffle (3) fixed on the sliding ends of the two linear modules (5), sliding downwards and closing until the bottom of the baffle (3) is attached to the top end face of a bottom plate (1), stopping the two linear modules (5), and observing and controlling polishing of parts through an observation mirror (6) arranged on the baffle (3), so that the operating personnel can be effectively prevented from being injured by splashing of sparks and scraps, a good working environment is ensured, the device is effectively protected, and the life safety of the operating personnel is protected;

fourthly, when grinding is carried out, the generated metal fragments fall to a U-shaped electromagnet plate (10) arranged in a through groove (24), the U-shaped electromagnet plate (10) is electrified to be started, the U-shaped electromagnet plate (10) is fixedly supported through a second rotating shaft (13) and a mounting plate (15), the fallen metal fragments are adsorbed and collected, and until grinding is finished or the fragments in the U-shaped electromagnet plate (10) are accumulated more, a first motor (11) on one side of a starting mounting base plate (1) is meshed with a first driven bevel gear (14) sleeved on an output shaft of the first motor (11) through a first driving bevel gear (12) sleeved on the second rotating shaft (13);

fifthly, then through rotating second pivot (13), overturn U type electromagnetism iron plate (10) downwards, then break off U type electromagnetism iron plate (10), U type electromagnetism iron plate (10) lose magnetic force, hold up that the metal piece on U type electromagnetism iron plate (10) drops to installing collection water tank (9) in bottom plate (1) bottom, and mix with the water of storage in collection water tank (9), avoid some tiny dusts to float, influence the air quality, heavier metal piece that can retrieve sinks into the bottom, be convenient for recycle once more, thereby can be abundant clear up and collect the metal piece that produces, avoid the device to pile up the piece, guarantee environmental quality, and also there is the recycle of metal resource.
