Description

Technical Field

[0001] This utility model specifically relates to an oil-spinning machine for drying cutting oil from shaft parts, belonging to the technical field of automated processing equipment. Background Technology

[0002] In the automotive manufacturing industry, the performance of shaft parts, especially crankshafts, directly affects the overall efficiency of the engine. As a key component of the engine, the crankshaft plays a vital role in converting connecting rod force into output torque. The surface roughness of the crankshaft journal has a significant impact on the performance of the part. Therefore, fine polishing of the crankshaft is an essential step. However, with the rapid development of the automotive market, the demand for crankshaft polishing is increasing, leading to a surge in the consumption of polishing oil. Furthermore, the oil residue left on the crankshaft after polishing seriously contaminates subsequent processing equipment, which has a negative impact on the overall operating efficiency and environmental cleanliness of the workshop.

[0003] Because traditional polishing processes cannot effectively control the use and residue of polishing oil, engineers began to explore more efficient solutions. A new type of cutting oil spin dryer for shaft parts was developed. This equipment can significantly reduce the consumption of polishing oil and avoid pollution problems through effective oil spin treatment, thereby improving the flexibility and environmental friendliness of the production process. The effective implementation of this technology can not only reduce the dependence on polishing oil, but also greatly reduce environmental pollution and equipment wear while ensuring processing quality. It has important practical significance and application prospects.

[0030] Working Principle: The equipment relies on a crankshaft lifting device to rotate shaft parts. High-pressure gas is sprayed onto the surface of the shaft parts through the air nozzle 12, using centrifugal force to throw off the attached cutting oil. The dried shaft parts are discharged from the air tank 7 and placed on the oil-throwing device. The crankshaft lifting device lifts and rotates the shaft parts, and the air nozzle 12 sprays high-pressure gas to remove the cutting oil using centrifugal force. The centrifugally thrown-off cutting oil is collected by the suction device and enters the oil mist recovery device 8. The cleaned shaft parts fall through the positioning mechanism or are transported to a designated position through other devices. The shaft parts are fixed by the driven shaft device or the drive shaft bracket 37 and rotate under the drive of the motor, applying centrifugal force to dry the cutting oil. Through the coordinated work of the crankshaft lifting device, the power head device, the driven shaft device, and the oil-throwing station, efficient oil removal processing of shaft parts is achieved. The crankshaft lifting device, through the cooperation of the locking cylinder and the lifting platform 24, ensures the safety of the shaft parts. Stable lifting and lowering; the oil mist recovery device 8 and oil recovery trolley 9 in the oil recovery device effectively recover oil mist and excess oil during the degreasing process, keeping the environment clean. The power head device ensures the precise rotation of the shaft parts through the precise control of the rotary servo motor 27 and the active shaft center 53, improving processing efficiency. The driven shaft device achieves stable fixation of the shaft parts through the cooperation of cylinders and bearings, ensuring safety during the processing. The working principle is as follows: the crankshaft lifting device sends the shaft parts to the oil-slinging station. The power head device drives the shaft parts to rotate through the rotary servo motor 27. The jet nozzle 12 sprays compressed air to centrifuge and degrease the shaft parts. The oil-slinging base 23 guides the shaft parts to be accurately positioned through the guide rod 22. At the same time, the shaft parts are angled by the angular straightening cylinder 19. Throughout the process, the oil mist recovery hood 43 collects the generated oil mist and cutting oil, which are then recovered through the oil recovery device to keep the processing environment clean.
