本文通过分析在磨削加工细长轴时,为了防止工件变形,解决采用一般中心架支承时出现的问题,自行设计了一套辅助支架。该支架在磨削过程中不会随着工件的轴向进给运动而改变其相对于砂轮的位置,这样就能够时时抵消切削时的径向和切向分力。另外,增设百分表,可以边磨削边检测工件的形位误差。经使用证明该支架结构合理、操作简便,符合设计要求。
In this paper, the analysis of grinding slender shaft, in order to prevent the workpiece deformation, to solve the problems arising when the use of the general center frame support, designed a self-supporting bracket. The bracket does not change its position relative to the grinding wheel along with axial feed movement of the workpiece during grinding, so that the radial and tangential force components during cutting can be offset from time to time. In addition, the addition of dial indicator, you can side edge grinding while testing the shape of the workpiece error. The use of the stent proved to be reasonable, easy to operate, in line with design requirements.
