Abstract

The invention discloses a quick-tool-design-oriented fixed joint surface database and a creating method thereof. The database comprises a fixed-joint-surface dynamics knowledge base, a fixed-joint-surface design module, a fixed-joint-surface interface characteristic database, a bolt model-selection knowledge base, a bolt-hole driving parameter database, a fixed-joint-surface bolt-mounting-hole design module, a bolt-mounting-hole correlative characteristic database, a standard structure parameterized modeling module and an assembly constraint creating module. The creating method includes designing a joint surface according to dynamics needs of tool fixed joint surfaces, performing automated design of a bolt mounting hole structure according to a joint surface structure, completing parameterized modeling of a large-size joint-part standard structure of a tool according to the joint surface and the mounting hole structure, and automatically creating an assembly constrained relationship of the joint surface. Automated creation of the fixed joint surface during designing of the tool, the parameterized modeling and automated assembly of correlative characteristics of a tool structure member can be realized, technical support is provided to quick design and assembly of the tool.

Description

technical field [0001] The invention relates to a machine tool digital design database. In particular, it relates to a fixed joint surface database and its establishment method for rapid design of machine tools. Background technique [0002] In the process of machine tool design, the designer will inevitably encounter the design problems of the fixed joint surface and the associated structure, including the shape and size design of the fixed joint surface, the design of the dynamic performance of the joint surface, and the design of the connecting screw hole structure. The quality of the fixed joint surface treatment will directly affect the key performance of the machine tool such as precision and static and dynamic stiffness. [0003] Fixed joint surfaces and related structures appear frequently and highly repetitive in the process of machine tool design, which increases the workload of designers and prolongs the design cycle of products. Therefore, in order to solve the...
