偏心轴在车床上加工时,由于加工的偏心部位在轴的中间,并与车床主轴中心重合,偏心轴的重量偏移在主轴中心以外。当旋转时,因偏心离心力大、刚性差,容易引起扎刀而损坏零件、夹具或机床。为此,选用刚性好、牢固可靠的组合夹具结构,来保证偏心轴质量和安全生产。我们用组合夹具元件组装了一套车偏心的组合夹具(附图),加工偏心轴的部位为φ210d_4外圆,加工余量为3～5毫米。使用效果很好,加
When the eccentric shaft is machined on the lathe, the eccentric weight of the eccentric shaft deviates from the center of the spindle due to the machining eccentricity being in the middle of the shaft and coinciding with the center of the lathe spindle. When rotating, due to eccentric centrifugal force, poor rigidity, easy to cause damage to parts, fixtures or machine tools. To this end, the selection of rigid, solid and reliable combination of fixture structure to ensure the quality and safety of eccentric shaft production. We use a combination of components to assemble a set of car eccentric combination fixture (with photos), the processing of eccentric shaft parts φ210d_4 cylindrical, allowance for the 3 to 5 mm. Use good effect, plus
