on second rack (34), the rotatable two second gears (37) that are provided with in inside of bearing cover (36), two second gears (37) symmetry, and two second gears (37) all are connected with second rack (34) meshing, two clamping jaw (35) are fixed to be established on two second gears (37), the bottom sliding connection of blowing frame (5) has a fourth slip table (38), the top fixed connection of fourth slip table (38) and base (1), the symmetry is provided with a plurality of overlap joint groove (39) on blowing frame (5), the highly of blowing frame (5) and the highly unanimous of first tight awl (24), the tight awl (29) of second clamp, the side at supporting seat (11) is established in conveyer (13), receive magazine (14) laminating setting at the side of conveyer (13) and with the top sliding connection of base (1), and a handle (40) is arranged on the material receiving box (14), two electric push rods (41) are symmetrically arranged between the first clamping component (9) and the second clamping component (10), the output end of each electric push rod (41) is vertically upward, the output end of each electric push rod (41) is fixedly connected with a lapping sleeve (42), the top of each lapping sleeve (42) is a concave arc structure which is attached to the outer wall of the crankshaft, two guide sleeves (43) are fixedly arranged on two side walls of the block-shaped sliding table (26), a guide rod (44) is inserted into each guide sleeve (43), one end of each guide rod (44) is fixedly connected with a support rod (45), the other end of each guide rod is provided with an anti-falling sleeve (46), the bottom of each support rod (45) is fixedly connected with the top of the base (1), and before crankshaft polishing, firstly, the crankshafts are placed on the lapping grooves of the material placing frame in batches through manual work, when the crankshafts are polished, the two clamping jaws clamp the crankshafts to polish, at the moment, the fourth sliding table drives the material placing frame to slide towards one end close to the clamping jaws so as to sequentially convey the crankshafts on the lapping grooves, when the crankshafts are polished, the switch button is firstly started, so that the output end of the starting cylinder extends towards one end close to the clamping assembly, the output end of the starting cylinder is fixedly connected with the second rack, so that the second rack is driven to extend towards one end close to the base in the supporting cover, the two second gears are driven to rotate clockwise and anticlockwise in the supporting cover due to the fact that the two second gears are both in meshed connection with the second rack, and the clamping jaws are fixedly arranged on each second gear, so that the distance between the two clamping jaws is reduced, and the crankshafts are clamped, the output ends of the two electric push rods rise upwards until the output ends of the two electric push rods rise to be consistent with the heights of the first clamping cone and the second clamping cone, then the two clamping jaws are loosened, a crankshaft is placed in a lap joint sleeve on the output ends of the two electric push rods, the top of the lap joint sleeve is designed into a concave arc structure which is attached to the outer wall of the crankshaft, the crankshaft is more favorable for containing the crankshaft, after the crankshaft is clamped on the lap joint sleeve by the two clamping jaws, the second sliding table is started, so that a T-shaped table on the second sliding table is controlled to slide towards one end close to the second clamping cone, the driving motor is fixedly arranged at the top of the T-shaped table, the driving motor is driven to slide towards one end close to the second clamping cone, and the first clamping cone is sleeved on the output end of the driving motor, so that the first clamping cone is driven to slide towards one end close to the second clamping cone, until sliding to abut against one end of the crankshaft, then starting the double-shaft motor, thereby starting the output end of the double-shaft motor and driving the two first gears on the double-shaft motor to rotate, because the two first gears are meshed with the two first racks, the two first racks are driven to slide towards one end close to the first clamping cone, and because the two first racks are fixedly connected with the bottom of the block-shaped sliding table, the block-shaped sliding table is driven to slide towards one end close to the first clamping cone, and further the second clamping cone on the block-shaped sliding table is driven to slide towards one end close to the first clamping cone until sliding to abut against the other end of the crankshaft, so that the crankshaft is clamped and fixed by resultant force of the first clamping cone, the sliding block at the top of the block-shaped sliding table slides in the sliding plate above the block-shaped sliding table, so that the block-shaped sliding table can be limited, and further stable operation can be, the guide function is realized, so that stable operation of the block-shaped sliding table is assisted, the anti-falling sleeve plays a role in preventing the guide rod from falling off from the guide sleeve, the support rod plays a role in supporting and fixing the guide rod, after the crankshaft is fixed by the first clamping cone and the second clamping cone, the driving motor is started to drive the crankshaft to rotate, as one end of the driving plate is hinged with the first sliding table and the middle part of the driving plate is connected with the first sliding table through the elastic rod, when the crankshaft rotates, an abrasive belt on the driving plate is abutted against the rotating crankshaft, one end of the driving plate rotates by taking the hinged seat as a circle center, the middle part of the driving plate is elastically connected with the first sliding table, the two forces are added to form an oscillation force acting on the rotating shaft, friction is generated when the oscillation force and the rotating shaft rotate, the crankshaft is further polished, the abrasive belt can completely polish multiple parts of the single crankshaft by the design of the first sliding table, thereby accessible control switch knob adjusts driving motor's rotational speed to satisfy the polishing requirement in different precision, after the bent axle polishing is accomplished, two clamping jaws press from both sides the bent axle to the conveyer on, then carry to the material collecting box by the conveyer, so that collect.
