摘　　要：定位方案中选择合适的夹具设计方案是非常重要的一个环节,是工件刀具维持正确位置的重要保证。过定位是不合理的定位,定位方案如果存在过定位问题,在工件加工中会产生严重后果。所以在确定工件定位方案时,要尽量避免过定位问题发生。相关工作人员应该根据定位基准快速判断定位方案是否存在过定位现象,及时处理错误的定位方案,减少产品生产前期准备工作,降低生产成本。Choosing the right fixture design solution in the positioning scheme is a very important part, and it is an important guarantee for the workpiece tool to maintain the correct position. Over-positioning is an unreasonable positioning. If there is a positioning problem in the positioning scheme, serious consequences will occur in the machining of the workpiece. Therefore, when determining the workpiece positioning scheme, try to avoid over-positioning problems. Relevant staff should quickly judge whether the positioning scheme has been positioned according to the positioning benchmark, timely handle the wrong positioning scheme, reduce the preparatory work of product production, and reduce the production cost.
