QL—280型高压清洗机是由电动机驱动曲轴,而后由曲轴带动三缸柱塞泵工作的。曲轴是该机中关键零件之一,其加工质量的好坏直接影响清洗机的质量。曲轴的曲轴颈加工是一道关键的工序,为此,我们制造了一套三曲轴颈车床夹具来加工三个曲轴颈。通过生产实践证明,既可保证三个曲轴颈加工精度达到设计要求,又大大提高了生产效率。 QL-280 high pressure washer is driven by the motor crankshaft, and then driven by the crankshaft three-cylinder piston pump work. Crankshaft is one of the key parts of the machine, the quality of its processing directly affect the quality of the washing machine. Crankshaft crankshaft machining is a key process, for which we have manufactured a three-crankshaft journal lathe chuck to machine three crankshafts. Proved through the production practice, both to ensure that the three crankshaft machining accuracy to meet the design requirements, but also greatly enhance the production efficiency.
