5T龍門皮革下料機(jī)總體設(shè)計(jì)及傳動(dòng)系統(tǒng)設(shè)計(jì) 摘要：龍門皮革下料機(jī)是為了提高工作效率而進(jìn)行設(shè)計(jì)的專用機(jī)床，該機(jī)械主要用于皮革的切削。 通過分析皮革下料機(jī)的設(shè)計(jì)要求和設(shè)計(jì)原理，確定了總體方案，完成了傳動(dòng)零件的選定，設(shè)計(jì)非標(biāo)準(zhǔn)件和機(jī)床總體結(jié)構(gòu)。為實(shí)現(xiàn)下料機(jī)的預(yù)期功能，對(duì)其傳動(dòng)系統(tǒng)進(jìn)行了設(shè)計(jì)。擬定了傳動(dòng)方案，分配了各級(jí)傳動(dòng)比，完成了動(dòng)力和運(yùn)動(dòng)參數(shù)設(shè)計(jì)，以及結(jié)構(gòu)設(shè)計(jì)，并進(jìn)行有關(guān)的計(jì)算和校核等。根據(jù)下料機(jī)切削皮革的要求，選用曲柄滑塊機(jī)構(gòu)來控制工作行程，對(duì)曲柄滑塊機(jī)構(gòu)的運(yùn)動(dòng)進(jìn)行了分析。所設(shè)計(jì)的龍門皮革下料機(jī)的工作效率高，能夠準(zhǔn)確的運(yùn)動(dòng),傳動(dòng)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(zhǔn)確的切除。 關(guān)鍵詞：專用機(jī)床;曲柄滑塊機(jī)構(gòu);傳動(dòng)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
