5T龍門皮革下料機總體設計及傳動系統(tǒng)設計 摘要：龍門皮革下料機是為了提高工作效率而進行設計的專用機床，該機械主要用于皮革的切削。 通過分析皮革下料機的設計要求和設計原理，確定了總體方案，完成了傳動零件的選定，設計非標準件和機床總體結(jié)構。為實現(xiàn)下料機的預期功能，對其傳動系統(tǒng)進行了設計。擬定了傳動方案，分配了各級傳動比，完成了動力和運動參數(shù)設計，以及結(jié)構設計，并進行有關的計算和校核等。根據(jù)下料機切削皮革的要求，選用曲柄滑塊機構來控制工作行程，對曲柄滑塊機構的運動進行了分析。所設計的龍門皮革下料機的工作效率高，能夠準確的運動,傳動平穩(wěn)可靠，使用安全,易于維修，滿足了下料分切干燥要求，工作行程便于調(diào)整，能保證所需皮革樣式準確的切除。 關鍵詞：專用機床;曲柄滑塊機構;傳動系統(tǒng) 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
