Abstract
The invention provides a longitudinal magnetizing device for a crankshaft magnetizing machine, which is characterized by comprising a motor board and a chain wheel board, wherein a linear guide rail is arranged between the motor board and the chain wheel board, a motor and a driven chain wheel are respectively arranged on the motor board and the chain wheel board, a driving chain wheel is arranged on an output shaft of the motor, at least seven coil fixed frames are arranged on the linear guide rail through sliding devices on two sides, each two fixed frames are connected through a telescopicmechanism, a coil is vertically arranged on each fixed frame, the driving chain wheel and the driven chain wheel are connected through a chain, and the spacing interval between each two coils is the same after expanding the telescopic mechanisms. The longitudinal magnetizing device for the crankshaft magnetizing machine has the advantages of completing the longitudinal magnetization of overall length of a crankshaft with the length of 800mm-1500mm once, leading the magnetization of all parts of the crankshaft to be sufficient and uniform, and realizing safety, reliability and low fault rate.
Description
technical field [0001] The invention relates to a longitudinal magnetization device for a crankshaft magnetization machine, which is used for magnetic particle flaw detection of a diesel engine crankshaft. Background technique [0002] The diesel engine is the heart of vehicles and power equipment such as automobiles, tractors, and ships, and the crankshaft is an important part of the diesel engine. When the diesel engine is working, the crankshaft rotates at a high speed to transmit power. If there are defects such as cracks on the crankshaft due to material quality and processing, the crankshaft may break and the machine may fail during use, endangering personal safety and causing economic losses. Therefore, it must be inspected for flaw detection during the manufacturing process of the crankshaft. From the perspective of fracture mechanics, the risk of surface defects is much higher than that of internal defects of the same size, so the magnetic particle inspection equip...
