Embodiment Construction

[0049] The specific operation steps of the present invention will be described in conjunction with the accompanying drawings and examples. The main drive structure of the headstock has a decisive influence on the machining accuracy of the machine tool. Therefore, when remanufacturing the waste machine tool, it is of practical significance to remanufacture the innovative design of the headstock to improve its performance. The factory currently recycles the waste CA6140 headstock spindle with a maximum rotation speed of 1400r / min, a minimum rotation speed of 11r / min, and a 24-stage variable speed. The main drive motor model is Y132M-4. By selecting typical structural features, the matter-element model M of the original waste spindle box was established 0 as follows:

Abstract

The invention discloses a waste machine tool remanufacturing innovative design method based on TRIZ and an expandable diverging tree. The waste machine tool remanufacturing innovative design method includes the steps that firstly, a formal matter-element model of a waste machine tool remanufacturing design target structure is built, by determining types of elements impeding waste machine tool innovative design, a matter-field model or a contradiction matrix is adopted to obtain innovation principles, structure innovation design is conducted on the formal matter-element model of the target structure according to the innovation principles, and then the expandable diverging tree comprising a number of candidate matter elements is formed; then, an expandable correlation function based on lateral distances and place values is introduced to represent correlation degrees between the candidate matter elements and expected matter elements, then, priority-degree values of the candidate matter elements are obtained through an expandable priority-degree evaluating method, and finally, an optimal candidate matter element is decided. By the adoption of the waste machine tool remanufacturing innovative design method based on the TRIZ and the expandable diverging tree, limits on design freedom in the structure, functions, materials and the like of an original waste machine tool can be effectively eliminated, and therefore a manufactured machine tool has higher market competitiveness and customer satisfaction.

Description

technical field [0001] The invention belongs to the field of machine tool remanufacturing, and in particular relates to an innovative design method for remanufacturing waste machine tools based on TRIZ and extension divergent trees. Background technique [0002] As the industrialization of remanufactured machine tools continues to deepen, the market and customers not only hope that the performance, cost, reliability and other technical and economical aspects of remanufactured machine tools are the same as those of new machine tools, but also expect their comprehensive performance to be improved. This requires the re-planning and design of the functional structure of waste machine tools and their waste parts. However, compared with the design of new machine tools with higher degrees of freedom, the fixedness of waste machine tools in terms of function, structure, and materials severely reduces the degree of freedom in design and greatly increases the difficulty of design. Th...
