Operation principle explanation of the present invention:
Reinforcing bar (3) maybe needs to process article when by rust remover, and rust remover built-in motor (11) drives power gear (12), thereby gravity gear (13) is rotated.Gravity gear (13) drives heart polishing wheels (15) to carry out the revolution centered by central principal axis (17) or reinforcing bar (3) by central principal axis (17), because fixed gear (14) is by gear mechanism transmission principle, so drive in the time of heart polishing wheels (15) revolution, borrow powershift gear (19) thereby drive power transmission gear (20), by gear mechanism transmission principle power transmission gear (20), drive sprocket (21), sprocket (21) drives polishing wheel shaft gear (22) again, thereby make polishing wheel main shaft (23) rotation, drive polishing wheel (24) rotation on polishing wheel main shaft (23) to be reached for reinforcing bar (3) rust cleaning polishing action.
Automatic derusting machine is in rust cleaning, polishing, can also unclamp gim peg (38) rotary handle dish (37) drivening rod (36) thus drive little right angle helical gear (35), by right angle helical gear machine driving former inner transmission large right angle helical gear (34), rotate, thereby drive chain (33), chain (33) drives four chain pitch wheels (32) synchronous rotary more simultaneously, because thering are the gear teeth on chain pitch wheel (32), inside there is helical tooth, so can drive worm screw (31) to forward and backward movement, thereby promote to be fixed on push pedal (30) on worm screw (31) to forward and backward movement.When push pedal (30) moves forward, the push rod (27) that pushing rolling wheels (28) makes and roller (28) links together also travels forward, push rod (27) promotes sliding shoe (25) by brace (26), and move at polishing wheel main shaft (23) the Ke Xiang center that makes to be fixed on sliding shoe, thereby reach the centre distance of turning two groups of polishing wheels (24) down.When push pedal (30) is moved backward, extension spring (39) pulls sliding shoe (25) outwards to move, thereby tune up the centre distance of two groups of polishing wheels (24), simultaneously push rod (27) moves backward, roller (28) or near push pedal (30) thus the upper work energy that reaches the centre-to-centre spacing of adjustable two groups of polishing wheels (24).
Above embodiment is the more preferably specific embodiment a kind of of the present invention, the common variation that those skilled in the art carry out within the scope of the technical program and replace and should be included in protection scope of the present invention.
