ABSTRACT
A reconfigurable multi-spindle box for holes machining is presented in this paper, which is an important function autonomy module belonging to reconfigurable machine tools. This type of a reconfigurable multi-spindle box has a range of production flexibilities for the manufacturing of the part family. When the number and the distances of the holes on the different machining parts change, the reconfigurable multi-spindle box can meet the machining requirements of the holes on the parts in a part family greatly by adding or decreasing the number of spindle modules and adjusting the distance between the spindles. The positioning and clamping components such as bolts, linear guides, parts with comb teeth and other parts are applied in the reconfigurable multi-spindle box, in which positioning precision is high. Each spindle of the reconfigurable multi-spindle box in the front-end, middle and back-end is clamped tightly by using specialized clamping devices, which ensures that the spindle has the reliable position accuracy and high support stiffness.
