Abstract

The invention belongs to the technical field of manufacturing of welded structures and combined square boxes, and discloses a precision machining method for a large-sized combined square box of a welded framework structure. The large-sized combined square box of the welded framework structure is formed by combining and splicing two sub-box bodies, each sub-box body is of a box body structure formed by splicing and combining a front plate, a rear plate, a top plate, a bottom plate and two side plates, and a vertical plate is arranged in each box body structure. The precision machining method comprises the steps of controlling the state of part materials, controlling the size allowance of the parts before the sub-box bodies are welded, coordinating the machining datum after the sub-box bodies are welded, machining the sub-box bodies and assembling the two sub-box bodies. According to the precision machining method for the large-sized combined square box of the welded framework structure, by analyzing the product structure and the forming mode, corresponding measures are provided from the aspects of datum design, allowance coordination, the technological process and the like, the problems that the allowance coordination difficulty is large, and the product precision is difficult to control are solved, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing welded structures and combined square boxes, in particular to a precision machining method for a combined square box with a large skeleton welded structure. Background technique [0002] The combined square box based on the skeleton welding structure is an important part of the model product. It mainly provides the installation structure of optical instruments and stand-alone machines. Due to the large size and complex internal structure of the square box, the combined molding method of welding, machining and assembly is generally adopted. This type of product requires high geometric tolerance and assembly accuracy. Due to factors such as product welding deformation, processing scheme design, spare part design, post-welding datum coordination, equipment selection and other factors, the geometric tolerance of the product is not easy to control, and the two boxes There is a problem of inconsi...
