我厂为加工汽车钢板后托架吊耳的锥孔,而设计制作了机械夹固式锥孔镗刀。用这一镗刀在车床上加工锥孔,不需重复调整刀具,利用车床纵向自动进给,一次进刀即可完成。具有使用方便,装夹安全可靠,保证加工质量等特点。刀具结构如图所示,由刀头1、压块2、刀体8等件组成。刀具安装在车床主轴锥孔内,随主轴正转,工件通过夹具安装在中拖板上,随大拖板纵向自动进给。加工时,刀头1对工件
I plant for the processing of automotive steel plate bracket lug taper hole, and design and manufacture of mechanical folder solid cone boring knife. Use this boring tool to machine taper hole in the lathe, do not need to adjust the tool repeatedly, use the lathe to feed in the longitudinal direction automatically, one time to feed and finish. With easy-to-use, safe and reliable installation, ensure the quality of processing and so on. Cutter structure shown in the figure, from the first bit, the pressure block 2, 8 and other components knife body. Tool installed in the spindle taper hole lathe, with the spindle forward, the workpiece through the fixture installed in the drag plate, with the vertical length of the automatic feed pallet. Machining, the first cutter on the workpiece
