The Key Technologies Of GTM500200Lathing And Milling Center Ram Design

GTM500200mobile gantry lathing and milling machining centers can achieve a one-time chucking parts, can be realized on the part cylindrical, bore, face turning, but also on the part of the plane, slope, surface, surface milling and other special processing, boring, drilling, tapping, quenching, grinding and other processing methods, perfectly adapted to the domestic industry, electric power, aerospace and other industries for processing quality and production efficiency of large parts requirements.In this paper, a study on the design process of the development of the Shenyang Machine Tool Co., Ltd. was GTM500200mobile gantry lathing and milling center ram major components headstock part in some of the key technical issues; main components and mechanical ram to do comparative analysis, making key force component can be improved; mainly completed the following work:(1) To three-dimensional solid modeling software Solidworks platform, SolidWorks Simulation Finite Element Analysis for the ram body GTM500200mobile gantry lathing and milling machining centers finite element analysis.(2) Solution according to the technical design requirements, design and optimize the internal structure of the ram. Program uses a built-in spindle, saving space. Analyze and compare the slippery material and form pillow body.(3) Due to the effect of temperature changes in the state ram thermal elongation of different temperatures affect the accuracy of the workpiece, the proposed thermal elongation feedback of two solutions for this problem.(4) Z-axis ram rails using hydrostatic technology, increasing the accuracy and stability of machine tools, analysis and design of hydrostatic guideway Z axis.(5) In order to improve the efficiency of the machine can be designed to interface with a variety of ram attachment docking head different functions. In the end surface of the ram head left Annexes interface signal line interface and the cooling liquid interface power electric and gas lines, oil, spindle encoder including through such boring and milling head straight, right angle boring and milling head, achieve universal boring and milling head milling, boring, drilling, tapping and processing; through such quenching head, can be realized on quenching; through folders such as turning, multi-turning clip, to achieve the workpiece turning. Through these key components in the design phase study technical issues, force structure ram body has been optimized, so that the machine performance is improved, the quality of machine tools has been significantly improved. This research has important implications for the design optimization of machine tool products, and increasing product innovation competitiveness.
