我厂生产的28 ZLB-70轴流泵喇叭、导叶体等大件的法兰螺栓通孔φ25刮倒平面为φ46,过去都是钻模钻出通孔后,再用一般刀杆穿过通孔,从下面装上刮平面刀具进行倒刮,效率较低。用如图工具配合快换夹头进行上述部位加工时,能自动快速伸张和收缩,经使用后工效可提高三倍。工具结构简单,刮平面刀用销1接在带外套的刀杆上,用人字弹簧控制伸缩,外套上端有一个螺钉销7与刀杆上的Γ形导槽相配合,并在刀杆与套
I plant 28 ZLB-70 axial pump horn, guide vane and other large flange bolts through hole φ25 scraping plane for the φ46, in the past are drilling after drilling through-hole, and then the general arbor through Through-hole, from below scraping plane scraper mounted scraping, less efficient. With the figure tool with the quick change chuck for the above parts processing, can automatically expand and contract quickly, after use ergonomics can be increased threefold. The utility model has the advantages of simple tool structure, the utility model is characterized in that the utility model is characterized in that the utility model is provided with a pin 1 which is connected with an outer sleeve arbor and is controlled and retracted by a herringbone spring; a screw pin 7 at the upper end of the outer shell is matched with a Γ shaped guide groove on the arbor;
