在齿轮加工中,我们采用弹性薄壁定心夹紧套(如图1)夹紧,可适用于齿轮车外圆、滚齿和剃齿等,具有能保证精度,劳动强度低,操作方便,生产率高的优点。夹具结构见图2,是用来剃齿的。件2套在件1的φ25毫来外圆上,其配合在M段过盈量为0.111～0.15毫米,M段以右的配合间隙为0.004～0.007毫米。件2的右端与件3配合过盈为0.018～0.022毫米。工件套在件2上,在剃齿机液压顶针的轴向推力作用下,件2的环槽外发生弹性变形,外径增大,将工件
In the gear processing, we use flexible thin-walled centering clamping sleeve (Figure 1) clamping, suitable for gear wheel cylindrical, hobbing and shaving, etc., with to ensure accuracy, low labor intensity, easy operation, high productivity The advantages. Fixture structure shown in Figure 2, is used to shave the teeth. Pieces 2 sets of φ25 millimeters to the outer circumference of the piece 1, with the interference in the M section 0.111 ~ 0.15 mm, M section to the right of the gap of 0.004 to 0.007 mm. The right end of the piece 2 and the piece 3 with the interference of 0.018 ~ 0.022 mm. Work piece sets on the piece 2, in the axial thrust of the hydraulic thimble shaving machine, the elastic deformation of the outer ring groove 2, the outer diameter increases, the workpiece
