在数控加工中心小批量工件规模的生产加工工件时,常用手动推压圆环压力组合夹具进行的生产。在实际的生产中,当手动推压圆环压力组合夹具的力源装置,中间传力机构,夹具的嵌套圆环部分出现问题时,容易出现误差增大,撞刀等现象。本文就生产中当手动推压圆环压力组合夹具松动引起的误差和撞刀现象提出检查方案,保证在生产加工时保持夹具稳定,提高了生产效益。
In the NC machining center small batch size of the workpiece production and processing parts, the commonly used manual pressure ring clamp combination of production. In actual production, when the pressure source device for manually pressing the annular pressure combination fixture, the intermediate force transmission mechanism, and the jigs annular portion of the fixture are experiencing problems, the errors tend to increase, causing the knife to hit. This paper puts forward the inspection plan for the error caused by the loosening of the ring pressure combination fixture and the phenomenon of hit by the knife in the production to ensure the stability of the fixture during production and processing and improve the production efficiency.
