Abstract
The equipment manufacturing industry is the basic industry which provides the processing equipment for the national economy each profession, its upstream and downstream industry chain is long, provides the employment post many, the technology capital is dense, is each profession realizes the processing ability to upgrade, The important guarantee of product progress and the concentrated embodiment of national comprehensive strength. After years of development, China's equipment manufacturing industry has become an important pillar industry of the national economy. However, the advanced NC machine tools with high performance, high automation and high added value, represented by horizontal machining center, lags far behind the developed countries in equipment manufacturing. In the key period of adjusting the world industrial pattern, increasing the market demand of domestic machine tools and speeding up the revitalization of the equipment manufacturing industry, it is imperative to develop a high performance horizontal machining center. In this paper, the mechanical structure of MDH125 horizontal Machining Center is studied. MDH125 horizontal Machining Center is one of the leading horizontal machining centers with domestic and international advanced level, which is developed and produced by Dalian Machine tool Group Co., Ltd. The machine tool is widely used in the processing of box parts, shell parts, disk parts and special-shaped parts in the fields of military industry, aerospace, automobile, mould, machinery manufacturing and so on. The parts can be milled, boring, drilling, expanding and hinging automatically after a single clamping. Multi-process processing of tapping. Combined with the development of new products of horizontal machining center, a design scheme of driving device for horizontal axis of machining center is briefly discussed in this paper. According to the machine tool parameters of many excellent horizontal machining centers at home and abroad, considering the market demand, market competitiveness, product structure and other factors, the initial design parameters are determined, and the structural layout of various horizontal machining centers is analyzed. Considering the overall rigidity, machine performance, manufacturing cost, easy to operate and other factors, to determine the practical scheme.
Keywords: horizontal machining center; horizontal axis; driving device
