在镗床或专用机床上镗孔时,我们设计制造了一种新颖的调刀装置。经过实践证明,这种调刀装置适用于各种镗床、铣床、专用机床、组合机床上的不同直径镗杆的粗调、半精调、精调刀片。一、使用方法及结构原理(见装配图) 使用调刀装置时,先把V型块靠在要调刀片的镗杆上,同时把调刀螺钉对准刀片的后端,用手扳动快速夹紧饭绕V型块旋转到镗杆中心线位置,锁紧手柄并拧紧夹紧螺钉,这样,调刀装置就可靠地紧固在要调刀片的镗杆上,然后拧动螺钉推动刀片进刀,即粗调或半精调刀片;对要求精度较高的孔时,拧动微调螺钉推动斜面销、微动块,推动调刀螺钉和刀片,即可微量进刀。斜面销的斜度为10°,当拧动螺钉转动一周时,镗刀片相对于镗刀杆移动的距离是0.176mm,螺钉的头部上刻有50等分的刻度,每转动一小格时,刀片只移动0.176/50=0.0035(mm),刀片位移量很小,即
When boring on a boring machine or a special machine, we designed and manufactured a novel toolsetter. After practice, this knife adjustment device is suitable for a variety of boring machines, milling machines, special machine tools, combined machine tools of different diameters boring bar coarse, semi-fine, fine adjustment blade. First, the use of methods and structure of the principle (see assembly drawing) When using the knife setting device, the first V-block on the boring bar to be adjusted blade at the same time adjust the knife screw at the back of the blade, hand fast Clamp the rice around the V-block to the center of the boring bar, lock the handle and tighten the clamping screw so that the knife guard is securely fastened to the boring bar of the blade to be adjusted and then tighten the screw to push the blade Knife, that is, coarse or semi-fine adjustment of the blade; For precision requirements of the hole, tweak the fine-tuning screws to promote the bevelling pin, micro-block, push the knife and screw blade, you can trace the knife. The slope of the bevelling pin is 10 °. When the screw is rotated one turn, the distance that the boring blade moves relative to the boring bar is 0.176 mm, and the head of the screw is engraved with 50 equally divided graduations. Each time a small grid is rotated , The blade moves only 0.176 / 50 = 0.0035 (mm), the blade displacement is small, that is
