如右图所示为片式反锪钻,其结构形式是从国外引进的,与我国常用的结构比,其优点是结构合理,使用方便,通过实际使用很受操作工人的欢迎。该片式反锪钻通过螺母在刀杆的螺纹部位旋转,带动偏销,使顶杆向右顶紧锪刀片,进行锪孔。锪完孔后,反旋螺母使偏销带动顶杆向左,则可使刀片松开取出。偏销是从螺母外圆处所开的偏孔中装入刀杆与顶杆的相应偏孔中连接一起,实现顶紧与松开片刀的动
As shown on the right is a chip anti-drill, the structure of the form is imported from abroad, and our commonly used structure than its advantages are reasonable structure, easy to use, by the actual use of very welcomed by the operatives. The chip counter-drill through the nut in the threaded portion of the cutter bar rotation, driven by bias, so that the mandrel to the right top tight 锪 blade for cusp.锪 finished hole, the anti-rotation nut to drive the ram to the left, you can make the blade loosen and remove. Partial sales is off the hole from the nut to open the hole into the corresponding arbor and ram hole connected together to achieve the top tight and release the blade move
