在铣加工中,经常遇到用两把三面刃铣刀加工零件,当工件尺寸有公差要求时,调整轴向尺寸往往采用选择或配磨垫圈的方法,这需要试切、更换垫圈、装卸刀轴螺母,增加了辅助工时。我厂在生产轮胎式推土机固定盘的过程中,改革了过去的方法,采用了轴向可调垫圈,使原来每更换一次刀具需要60分钟左右,减少到15分钟,节省了不少的辅助工时。可调垫圈的结构如图1,调整螺母2拧在调整套3上,由定位键1插入件
In the milling process, often encountered with two three-sided cutter processing parts, when the workpiece size tolerance requirements, the adjustment of the axial size is often used to choose or wear the washer method, which requires cutting, replacement of gaskets, loading and unloading knife Axial nut, an increase of auxiliary working hours. I plant in the production of tire-type bulldozer plate fixed, the reform of the past methods, the use of axially adjustable washers, the original tool for each replacement takes about 60 minutes, reduced to 15 minutes, saving a lot of helper hours . Adjustable washer structure shown in Figure 1, adjusting nut 2 screwed on the adjustment sleeve 3, the positioning key 1 by the insert
