摘　　要：FST-009数控车床夹具的设计存在一定的问题，依据设备说明书的转速加工中45~60mm之间滚子时，因夹紧力不够，出现让刀、工件转动等现象；当降低转速加工西45~60mm之间滚子时，虽能满足要求，但大大降低了生产效率，无法充分发挥该类设备的利用率。为了不降低转速同时又能够加工西45~60mm之间的滚子，对夹具进行了改进，由三爪夹盘改为弹性夹盘，使设备的利用率提高了一倍，满足了生产需要。FST - 009 CNC lathe fixture design had certain problems, when processing rollers between qb45 to 60 mm according to equipment manuals rotational speed, due to insufficient clamping force, cutter back-off of tool and no clamping material appeared; when processing rollers between qb45 to 60 mm at lower rotational speed, although the requirements can be met, but the production efficiency was reduced greatly, and unable to give full play to the equipment utilization rate. In order to not reduce the speed at the same time, also can processing the rollers between φ45 - 60 mm, the fixture was improved, three-jaw chuck was changed to elastic chuck to increase equipment utilization 1 time and meet the needs of production.
