Title  Small Twist Drill Grinding Machine Three-dimensional Design
Abstract
According to the grinding of twist drills and working conditions required, a small twist drill grinding machine of the overall structure is designed, the dimensions of a small twist drill grinding machine is established. According to the standard twist drill bit geometry characteristics, and through the main blade and the posterior horn and its mathematical model analysis and the identification, In the drilling clamp adjusting sleeve and with a bit eccentric hole of the upright as the core of the Department of twist drill grinding machine of supporting small-scale of the knife body and grinding bodies is developed. According to the design features of various enforcement agencies,  a sheet metal structure as the main structure is designed, and draw the corresponding mechanical structure diagrams and parts drawing. According to the relative position of each component, a reasonable layout structure. Important part of structural shaft of the necessary analysis and design, and its parameters are determined. Use of PRO/E 3D design software to draw a three-dimensional structure diagram, and the use of AutoCAD drawing two-dimensional drawings. 源￥自%六^^维*论-文+网=www.lwfree.cn
