下面介绍一种,装在工具磨床上的通用滚刀刃磨夹具。夹具的结构如图所示,主要由定位插座1、本体2、圆套7、心轴13、分度盘30、钢丝绳35等组成。心轴13上固定一个缠绕钢丝绳35的圆套7。钢丝绳同时固定在滑块28的两个支座38上,用螺母36、39及螺钉37拉紧,保证转动的圆套与滑块之间无间隙。滑块右端下方固定一个滚动轴承41,并在装于床身上的角度盘槽内运动,间距为轴承外径,间隙用隔块调整好。利用圆螺母5、9防止心轴13的轴向窜动。用螺钉21、螺母22调整滚 Here is a general, mounted on the tool grinder hob grinding fixture. Fixture structure as shown, mainly by the positioning socket 1, the body 2, the sleeve 7, mandrel 13, indexing plate 30, wire rope 35 and other components. The mandrel 13 is fixed with a round sleeve 7 wound with a steel wire rope 35. At the same time, the steel wire rope is fixed on two supports 38 of the sliding block 28, and is tightened with nuts 36, 39 and screws 37 to ensure no gap between the rotating circular sleeve and the sliding block. A rolling bearing 41 is fixed below the right end of the sliding block and moves in an angle disk groove which is arranged on the bed body. The spacing is the outer diameter of the bearing, and the gap is adjusted by the spacer block. The use of the round nuts 5, 9 prevents axial movement of the spindle 13. Use screws 21, nuts 22 to adjust the roll
