二十四孔钻削机床及夹具设计

摘要  介绍了本次设计的主要目的，通过对组合机床方案的拟定的分析确定该组合机床应采取单工位固定式夹具的卧式双面机床的配置形式。通过对切削力、切削扭距、切削功率及刀具耐用度的分析选择合理的刀具结构。通过对被加工零件工序图、示意图、机床联系尺寸图的分析，确定机床的总体设计方案。专用夹具通过V型块定位，液压缸夹紧装置，以减少辅助加工时间。通过选用可换钻套，钻套装在衬套中，衬套则是压配在夹具体或钻模板中，钻套由螺钉固定，以防止它在刀具加工时转动，便于钻套磨损后可迅速更换以达到提高工厂生产效率的目的。

Drilling Machine And Fixture Design of 24-hole
Abstract  The main purpose of design, through the combination of machine tool programming analysis to determine the combination of machine tools should be taken to a single fixed-position horizontal fixture configuration of the form of double-sided machine. Of cutting force, cutting torque, cutting power and tool life analysis tool to choose a reasonable structure. Parts were processed through the process map, diagram, map machines contact size analysis, machine design program. Dedicated fixture through the V-block positioning, hydraulic cylinder clamping device in order to reduce processing time auxiliary. Through the selection can be set for drilling, drilling suite in the bush, the bush is press-fit the specific folder or in the drilling template, drill sets fixed by the screw to prevent it from turning in the processing tool, easy to wear diamond sets can be quickly replacement in order to improve production efficiency.
