摘　　要：多点锥面定位是交换工作台型卧式加工中心中所采用的一种经典结构,针对传统结构在生产中存在加工难度大、废品率高、工作台拉紧时工作台台面变形大、生产周期长等问题,设计了一种新结构。该结构改变老结构工作台在拉紧时工作台直接受力同时采用灌胶技术代替传统轴孔配合定位,有效解决了传统结构在生产中存在的问题,提高了机床的加工精度。Multi-cone positioning adopted by exchange worktable of horizontal machining center is a type of classic structure. Considering the existing problems of the traditional structure in production, such as difficult to process, high rate of waste, worktable surface deformation when worktable is taut, long production cycle and so on, this paper designs a new structure, which changes the force affected directly of the old structure and simultaneously adopts glue technology. It solves the problems of traditional structures in production effectively, and enhances the machining accuracy.
