Yifan, computer engraving machine mechanical structure

Yifan, computer engraving machine mainly includes the axis and Z axis components, X, Y axis parts and worktable for part of the virtual assembly is shown in figure 1. Figure 1 yifan, computer engraving machine machine virtual assembly drawing to calculate the maximum principal cutting force Fc, determine the maximum spindle speed Vmax and output torque, selected models for EMP240 dc motor spindle motor, according to the load condition of the X and Y directions, the selected ball screw pair for GD series, at the same time, this article selected according to the load torque stepper motor model for 57 byg4504, choose the corresponding bearing, coupling, guide rail, round nut, design end cover, etc. Axis and Z axis parts: spindle motor, cutting tool installed components, to achieve the main movement of the machine tools and cutting tools under the Z direction carried knives and knife; X axis parts: stepper motor installation, bearing the weight of the spindle and the X axis parts, accomplish tool feed movement in X axis direction; Y parts: stepper motor installation, bearing the weight of the Y axis parts, achieve feed movement of cutting tool in the Y direction; The workbench: install fixture, workpiece was laid.
