This design is to drill the left side face of gear case combination machine tools, the main spindle box of modular machine tool design. Through analysis and comparison, to determine the selection of horizontal simplex bit left side face of combination machine tools for machining parts is; In order to ensure the machining accuracy, using a two pin positioning way; In order to achieve the infinite speed, safe and reliable, choose hydraulic combination sliding table; According to the size of the parts and processed hole location to determine the outline of the spindle box size; Through the calculate and determine the main shaft and the diameter of the shaft; Gear modulus is determined by analogy method; The gear teeth and the position of the intermediate shaft is by calculating, drawing and the combination of trial and error method to determine many times; Calculate the coordinates of main shaft, the shaft and calculating the center distance, determined in the light of the deflection of shaft gear; Shaft of the gear set, key parts such as press shaft, select the corresponding standard. Key words: combination machine tools; Spindle box; Main shaft; Transmission shaft; gear 目 录 前 言 1 第1章 绪论 2 §1.1 组合机床的发展史 2 §1.2 组合机床的国内外发展状况 2 §1.3 组合机床的分类和组成 4 §1.4 组合机床的特点 5 §1.5本课题研究的内容及意义 6 §1.6 组合机床设计步骤 6 §1.6.1 调查研究 6 §1.6.2 拟定方案 6 §1.6.3 工作图设
