目前,在工夹具设计工作中还存在许多问题,主要 的表现在工夹具的设计质量低下:一方面是设计出来 的工夹具不能完全保证加工零件的制造质量(如各主要箱体的镗孔夹具,某些较复杂的镗、钻、车、铣、磨等 的工夹具),以致在生产中造成大批废品与回用品;另 方面由於工夹具设计质量低 At present, there are still many problems in the work of fixture design. The main performance lies in the low design quality of the fixture: On the one hand, the designed fixture cannot completely guarantee the manufacturing quality of the processed parts (such as the boring jigs of the main boxes). , some of the more complex tools and tools such as hammers, drills, wheels, mills, and grinding tools, etc., that caused a large number of waste products and supplies in production; on the other hand, due to the low quality of fixture design
