该攻丝器是一种新型的孔螺纹加工工具,其特点是综合了以往攻丝机和简易攻丝夹头的优点于一体,具有体积小、通用性广、攻丝范围大等特点;并能在钻床不反转的情况下,只需将钻床操作手柄向上提,丝锥便可退出。下面结合附图,将其原理、结构及主要零件技术要求等向读者作一介绍,以便对该产品有一较深的认识。一、攻丝时动力传递路线攻丝时的动力传递路线如下:钻床→锥柄1→外壳2→传动销3→压簧25→离合器盖24→主动片4→摩擦片5→从动片6→离合器座22→正转齿套27→传动销23→空心轴13→制动螺钉
The tapping machine is a new type of hole thread processing tool, which features the advantages of the past tapping machine and the simple tapping chuck in one, and has the characteristics of small size, wide versatility and large tapping range; and In the case of drilling machine does not reverse, simply lift the drilling handle, the tap can exit. The following combination of drawings, the principle, structure and technical requirements of the main components such as a reader to make a presentation in order to have a deeper understanding of the product. First, the tapping power transmission line tapping power transmission line is as follows: drilling → taper shank 1 → housing 2 → drive pin 3 → compression spring 25 → clutch cover 24 → active plate 4 → friction plate 5 → follower plate 6 → clutch seat 22 → forward gear sleeve 27 → drive pin 23 → hollow shaft 13 → brake screw
