The present invention relates to a kind of fine broach with pulley and its assembly method, including broach, cutter head, positioning pin, wedge and fixed screw. In front of the broach and the end of the knife handle body is provided with a clamping groove fit the clamping end of the clamping end is made into a slope with certain gradient, and provided with a through hole matched with the positioning pin. The end of the tool handle is provided with a clamping slot, and a threaded hole matched with the fixed screw and a through hole matched with the positioning pin are arranged. The wedge has a slope, which is consistent with the inclination of the clamping end of the cutter body. Assembling method, the invention also relates to the wheel groove finishing broach comprises: a front end of the broach cutter body shank mounted terminal is arranged matched with the clamping groove; the positioning pin hole into the pull knife body and a handle at the front end of the inclined loading; iron broach knife body is arranged between the end of an empty slot with the end of the knife handle clamping groove, the oblique iron tapping under the sink tightly connected together until the broach knife body and a handle; the fixing screw into the handle and matched with the threaded hole.
【技术实现步骤摘要】
一种带刀柄式轮槽精拉刀及装配方法
本专利技术提供一种带刀柄式轮槽精拉刀。尤其涉及到一种加工汽轮机转子轮盘轮槽用的带刀柄式轮槽精拉刀。
技术介绍
在汽轮机制造中,汽轮机转子是汽轮机的动力部分,加工质量的好坏将直接影响到整个汽轮机的性能,而作为汽轮机的转子是其核心部分,多级轮盘是转子的主要组成部分。轮盘轮槽加工的质量将直接影响汽轮机的出力及振动情况,轮槽的加工是转子加工中最为关键、最为困难的环节。轮盘轮槽的加工由传统的专机铣削加工逐渐改为拉削工艺。加工多级轮盘轮槽拉刀以前均购买国外成品刀具,价格非常昂贵。
技术实现思路
本专利技术所要解决的技术问题在于提供一种用于卧式专用轮槽拉床的带刀柄式轮槽精拉刀。为解决上述技术问题,本专利技术提出一种带刀柄式轮槽精拉刀,所述带刀柄式轮槽精拉刀包括拉刀刀体、定位销、楔铁、固定螺钉及刀柄。拉刀刀体前端设有可与刀柄末端装夹槽配合的装夹端,该装夹端做成带有∠5o角度的斜面,并带有与定位销间隙配合的定位通孔。刀柄末端做有装夹槽并设有与专用螺钉相配合的螺纹孔和与定位销配合的定位通孔。楔铁带有∠5o的斜面,该斜面角度与拉刀刀体前端装夹端所带斜面角度一致。所述轮槽精拉刀的组装方法包括:将拉刀刀体前端装夹端装入与之相配的刀柄末端装夹槽;将定位销装入拉刀刀体与刀柄处的通孔;将楔铁装入拉刀刀体前端装夹端与刀柄末端装夹槽之间的空槽,敲击斜铁使之下沉直至拉刀刀体与刀柄紧密连接在一起;将固定螺钉装入刀柄上与之相配合的螺纹孔。本专利技术采用拉刀刀体和刀柄分开式结构,拉刀刀体采用高速钢,刀柄采用普通合金钢,由于刀柄采用的材料不影响刀具使用性能且价格更便宜,且 ...
