[0014] The crankshaft grinding oil vacuum suction device of the present invention has the following structure: Figure 2 and Figure 3 As shown, two linear guide rails 12 are installed in parallel on the base 10, a support plate 23 is installed between the front and rear linear guide rails 12, and both ends of the left and right sliding plates 11 are respectively installed on the linear guide rails 12 through sliders. The left suction module 21 and the right suction module 22 are respectively installed on the left and right sliding plates 11. The inner cavity structure of the left suction module 21 and the right suction module 22 matches the external structure of the crankshaft 19. The left suction module 21 and the right suction module 22 are provided with an air inlet 18, and the air inlet 8 is connected to the crankshaft 19. The left and right suction modules 21 and 22 are connected. A positioning support 17 for the crankshaft 19 is mounted in the middle of the support plate 23, parallel to the sliding plate 11. The external structure of the positioning support 17 matches the crankshaft 19. Drive cylinders 3 are mounted on the undersides of the front and rear linear guides 12, and their cylinder rods are connected to the two sliding plates 11 via connecting bent plates 16. A suction hole is provided on the support plate 23 below the positioning support 17, which connects to the first suction pipe 4. Brackets 14 are mounted on the outsides of the front and rear linear guides 12, corresponding to the ends of the positioning support 17. A photoelectric sensor 15 and a reflector 20 are mounted on the insides of the two brackets 14, respectively.
[0015] like Figure 1As shown, the suction system consists of a bed, a crankshaft profiling suction module 2, an oil mist processor 9, an oil return pipe 8, a pneumatic system, etc. The first suction pipe 4 is connected to the oil tank 6, the oil tank 6 is connected to the oil mist processor 9 through the second suction pipe 10, the oil mist processor 9 is connected to the oil tank 6 through the oil return pipe 8, and the oil tank 6 is connected to the crankshaft grinder through the oil pump 7 and the oil pipeline.
[0016] Working Principle: The truss manipulator 1 delivers the ground crankshaft 19 to the positioning support 17 of the suction device for positioning. A photoelectric sensor 15 and a reflector 20 work together to detect whether the crankshaft 19 is in place. A drive cylinder 3 drives the left and right contoured suction modules 2, enclosing the crankshaft 19 within the suction module. The suction hole in the support plate 23 is connected to the first suction pipe 4. Recovered oil is transported through the first and second suction pipes 10 to the oil mist treatment unit 9. The oil tank 6 is sealed to the oil mist treatment unit 9. The oil mist treatment unit 9 is activated to generate a vacuum suction pressure in the suction module through the suction pipes. The suction module is equipped with an airway. The suction effect and the contoured cavity cause air to flow downward along the outer surface of the crankshaft, removing any grinding oil adsorbed on the crankshaft surface. The air then flows through the first suction pipe 4 to the oil tank 6. The tank is equipped with an oil level sensor 5. When the oil level reaches the set value, the oil pump 7 starts and pumps the grinding oil back to the crankshaft grinder. When the oil level drops to the set value, the oil pump stops. Conventional oil mist processors incorporate an oil mist purification device. The purified grinding oil is collected in an oil tank 6 via an oil return pipe 8 and pumped back to the crankshaft grinder via an oil pump 7. The suction module is contoured to the crankshaft's shape, ensuring uniform clearances and forcing the suction airflow along the crankshaft surface, reliably removing the grinding oil. The suction path is securely sealed to prevent leakage and ensure effective suction.
