在家用电器的五金产品当中,如图1所示的沉孔较为普遍。随着生产技术的发展,机械化程度日益提高,我们设计了一种如图2所示微调钻杆,不附加任何工具就可进行钻杆的深浅调节。通过实际使用,效果显著。一、钻杆的使用本钻杆主要适用于多孔同时加工。如图1所示工件的3沉孔一次加工完成。加工时,如果其中1只钻头磨损,需要重新刃磨时,只要松开螺钉8,取下钻头刃磨好后, Household appliances in the hardware products, as shown in Figure 1 sink hole is more common. With the development of production technology, increasing degree of mechanization, we designed a fine tuning drill pipe shown in Figure 2, without any additional tool to drill pipe shades. Through actual use, the effect is remarkable. First, the use of drill pipe The drill pipe is mainly suitable for porous processing at the same time. As shown in Figure 1 workpiece sink hole processing completed. Processing, if one of the drill wear, you need to re-sharpening, just loosen the screw 8, remove the drill sharpened,
