Abstract :
Tolerance allocation is one key to designing and manufacturing of machine equipments. According to the assembly process of tubular-structure, this paper analyzes motion modes to achieve tubular-structure loading. In term of assembly tolerance of tubular-structure, a tolerance model to guide structure design of loading equipment is formulated. Based on tolerance analysis of each motion mode, the maximum available size of the tubular-structure is calculated under different linear rolling guide, and the minimum available size of the interior rail in the box is calculated under different ball screws, trapezoidal screw threads, worm and worm gears. To meet the tolerance of tubular-structure assembly, machine movement chains are defined.
