该滚压头用在自动车床上,在制品轴肩后滚压M12×1.5的螺纹(从主轴一侧开始滚)。其结构如图所示,它由铰接在刀柄5上的本体1和在轴2上自由转动的螺纹滚轮7组成。下面的滚轮在轴向不能移动,而上面的滚轮因有端面弹簧6可以移动滚压头的本体利用拉杆3调整,使得滚压头向零件送进时,下面的滚轮先在制品上滚压螺纹到一定深度。当径向力增大时,通过压缩碟形弹簧4,使本体稍微转动,于是上滚轮开始工作,该轮便按已滚压出的螺纹在轴
The roller head is used in automatic lathes to roll the M12 × 1.5 thread (roll from the spindle side) behind the product shoulder. Its structure is shown in the figure, which is composed of a body 1 hinged on the handle 5 and a threaded roller 7 which is freely rotated on the shaft 2. The lower roller can not move in the axial direction, and the upper roller can be moved by the end spring 6. The body of the rolling head is adjusted by the pull rod 3 so that when the rolling head feeds the part, the lower roller rolls the thread on the article To a certain depth. When the radial force increases, by compressing the disc spring 4, so that the body slightly rotated, so the wheel started to work, the wheel will be rolled out of the thread on the shaft
