我站机修厂没有刨床和铣床,车床上加工出来的轴都要送到很远的地、县级厂去加工键槽。为了加速实现我地区农业机械化,我们想办法自制了一个夹具,在现有的钻床上就可以加工键槽。夹具如图所示,工件由两个短V型块和压板夹紧固定在下钢板上,下钢板下面的移动螺母与丝杆连接,转动丝杆,下钢板就可在固定于钻床床面上的导轨上移动,得到横向进给运动。立铣刀夹在钻床夹头内,上面挂一只小桶,接一根塑料管供铣刀冷却用油。这样,只要一人操作,来回移动两次键槽就加工成功了。用这种夹具我们已加工了几十根轴的键槽,还代替刨床加工过一些精度 I plant mechanic no planing machine and milling machine, lathe machining out of the shaft must be sent to the far, county-level factory to process keyway. In order to accelerate the mechanization of agriculture in our area, we have found a way to make a fixture that can be keyed on existing drilling machines. Fixture As shown in the figure, the work piece is clamped and fixed on the lower steel plate by two short V-shaped blocks and the pressure plate. The moving nut under the lower steel plate is connected with the screw rod. When the screw rod and the lower steel plate are fixed on the bed of the drilling machine Move on the guide rail, get transverse feed movement. End mill clip in the drill chuck, hanging a bucket above, then a plastic pipe for cutter cooling oil. In this way, as long as one person operation, move back and forth twice the keyway processing success. With this fixture, we have processed dozens of key shaft keyway, planing machine also replaced some precision
