浮动导向套丝器(附图)是解决螺栓在车、钻床上进行套丝加工,防止丝扣歪斜而设计的。特点:(1)滚花螺母1前端有导向部分,使工件易进入圆板牙,加工第一圈螺纹时就能防止丝扣歪斜。(2)在板牙座3,尾柄体6间设中间体7,其上带有互相垂直的燕尾导轨,可在工件与板牙不严格同心时,能产生浮动而自动定心。(3)橡胶圈5起着约束中间体的作用,使板牙回复到中心位置。(4)利用锥柄中心挖空
Floating guide sleeve (Figure) is to solve the bolt in the car, drilling machine threading processing, to prevent the skew of the thread design. Features: (1) knurled nut 1 front-oriented part of the workpiece easy to enter the circular plate teeth, the first thread can be processed to prevent the thread skew. (2) An intermediate body 7 is arranged between the socket holder 3 and the tail handle body 6, and the dovetail guide rails perpendicular to each other are capable of generating a floating and self-centering position when the workpiece and the plate are not strictly concentric. (3) The rubber ring 5 plays the role of restraining the intermediate body, so that the back to the central position of the die. (4) taper center hollowed out
