The overall arrangement and main spindle part design for five-axis vertical machining center
Abstract：The five axis vertical machining center is one kind of synthesis machining ability strong numerical control machining equipment, the five axis vertical machining center collect a variety of machining function at a suit, work piece after a fixture of all kinds of small complex components can perform a variety of machining and five-axis complex surface machining. Passes through quite is definite this education small vertical processing center to the different movement plan and various parts design proposal qualitative analysis the overall project design is using the vertical layout, the main spindle part installs through the installment place in on the column guide rail slide rails, the column guide rail uses the trundle guide rail, may realize the Z direction feed motion. Were installed in the column below and above the linear guide connected to the the spindle slide and machine bed, to achieve X,Y axis linear feed motion. Install the cradle rotary table on the workbench, to achieve A , C -axis rotary feed motion . Five degrees of freedom of movement are controlled by the high - precision ball screw and rotary table with AC servo motor, and accurate five-axis machining control. Compares with the present domestic same type processing center, has the structure compact, the spatial size small, the processing precision high, the production efficiency higher merit.
Keywords: Five-axis ; overall layout ; kinematic chain ; high-speed electric spindle
