The purpose of this paper is to design suitable for high-speed HMC80 horizontal machining center, special fixture,mainly through the analysis of the main parts of the high-speed horizontal machining center processing, processing characteristics of the spindle box body, according to the processing technology, formulate feasible scheme of the chosen positioning scheme on the basis of the design to plan.Calculated in various parts of good positioning clamping scheme determined size, finally determine the overall structure size.Then use pro/E structure clamp specific parts assemble fixture assembly of 3 d model so that further detailed analysis was carried out on the design scheme, after defining the total fixture structure scheme using pro/E to make a specific assembly drawing and part drawing, will be dimensioning drawings into CAD need further modificatio
