5T龙门皮革下料机总体设计及传动系统设计
摘要：龙门皮革下料机是为了提高工作效率而进行设计的专用机床，该机械主要用于皮革的切削。
通过分析皮革下料机的设计要求和设计原理，确定了总体方案，完成了传动零件的选定，设计非标准件和机床总体结构。为实现下料机的预期功能，对其传动系统进行了设计。拟定了传动方案，分配了各级传动比，完成了动力和运动参数设计，以及结构设计，并进行有关的计算和校核等。根据下料机切削皮革的要求，选用曲柄滑块机构来控制工作行程，对曲柄滑块机构的运动进行了分析。所设计的龙门皮革下料机的工作效率高，能够准确的运动,传动平稳可靠，使用安全,易于维修，满足了下料分切干燥要求，工作行程便于调整，能保证所需皮革样式准确的切除。

Design of the Overall and Transmission Systems of 5T Gantry Machine for Cutting Leather
Abstract: 5T Gantry machine for cutting leather is for enhance the working efficiency to carry on the design the special purpose machine, this machinery mainly cuts the leather cutting. 
Pass after analysis that the machine design demands principle and design principle by a leather, have ascertained an overall plan, have accomplished selects of drive part, have designed the non- standard piece and machine tool overall structure. Be to come true anticipate that function design of transmission systems of machine for cutting. Have designed the drive scheme, have assigned all of the various levels transmission ratio, have accomplished driving force and have moved parameter design and physical design. And make use of what be mimicked knowledge carrying out relevant secretly scheming against and school core and so on. According to lower material machine request cutting a leather , come to control a working stroke selecting and using slider-crank mechanism organization, the organization motion has carried out analysis on slider-crank mechanism.
Design Gantry machine for cutting leather of working efficiency high, the nicety move, the transmission were stable , safe in utilization, was apt to maintenance, satisfies the yummy treats minute to cut the dry request, the power stroke is advantageous for the adjustment, could guarantee needed the leather style accurate excision.
Key word: single purpose machine; slider-crank mechanism; transmission system
