Abstract

With the rapid development in the field of machinery, people's demand for machined products has also shown diversified development. It is difficult for traditional machine tools to respond to diversified, small-batch customer demands in a cost-effective manner. Under this industry background, the research and manufacture of reconfigurable machine tools that are highly efficient, economical, and convenient have become an outlet for the machinery industry.

This article takes the gearbox as the demand product, carries on the thorough analysis to each part of its parts, as well as each kind of machine tool which needs to use, carries on the design of the desktop level reconfigurable horizontal lathe. The basic design process is as follows: Firstly, the components of the gear box that need to be machined are analyzed by the component family, and then the process family of the machining process is analyzed to determine the various movements corresponding to the various machining processes of the machine tool. Module division. The various types of modules required for the reconstruction of lathes were extracted and detailed design was carried out. Detailed description of the spindle drive system, as well as the design process of the feed drive system.

After the theoretical design was completed, SolidWorks was used to build a three-dimensional model of the reconfigurable lathe designed. Based on the work loads, cutting forces and torques calculated in the design, the three-dimensional model was subjected to finite element simulation analysis and was a realistic machine. The processing production process provides a theoretical basis.

Keywords : desktop level, reconfigurable, CNC machine, modular
