摘 要:顧名思義，多功能切菜機(jī)是一種可將多種根莖葉類蔬菜切制成多種樣式的機(jī)器。第一個設(shè)計的重點便是它的多功能，其多功能體現(xiàn)在兩個方面，一方面是能切的蔬菜種類多樣，如莖葉類蔬菜中的青菜、白菜、芹菜、四季豆、甘豆等，根莖類蔬菜中的土豆、番茄、紅蘿卜、大蒜、黃瓜、洋蔥等都能進(jìn)行切制；另一方面體現(xiàn)在能切出菜型的多樣化，如生活中一般需要用到的片、塊、絲、條、丁、段、末等菜式都能在該機(jī)器上實現(xiàn)。 另一個設(shè)計重點是實現(xiàn)該機(jī)構(gòu)在體積和質(zhì)量上有所減輕，合理的設(shè)計內(nèi)部結(jié)構(gòu)是減輕體積和質(zhì)量最重要的因素。 多功能切菜機(jī)的內(nèi)部結(jié)構(gòu)設(shè)計框架大體如下：首先由電動機(jī)輸出動力，然后通過一個簡易的變速機(jī)構(gòu)，該機(jī)構(gòu)是由電機(jī)主軸通過帶傳動帶動兩個可調(diào)式皮帶輪，中間加上一張緊輪構(gòu)成，通過調(diào)節(jié)可調(diào)帶輪輪徑來達(dá)到改變速度的目的。通過簡易的變速機(jī)構(gòu)將其動力分為三條，第一：變速機(jī)構(gòu)連接輸出軸輸出水平動力，通過一組標(biāo)準(zhǔn)直齒圓柱齒輪達(dá)到減速目的，再由一組標(biāo)準(zhǔn)直齒圓錐齒輪改變軸向力，將水平動力傳遞成豎直動力，由鏈傳動將動力提供給傳送帶，實現(xiàn)傳送帶的運動；第二：變速機(jī)構(gòu)連接輸出軸輸出水平動力，通過一組標(biāo)準(zhǔn)直齒圓錐齒輪將水平軸力傳遞到豎直方向，然后帶動平面偏心輪連桿機(jī)構(gòu)將往復(fù)運動傳遞給豎刀，實現(xiàn)豎刀的往復(fù)運動；第三：簡易變速機(jī)構(gòu)連接輸出軸輸出水平動力，輸出軸另一端與帶輪連接，通過帶傳動將動力傳遞給離心圓盤刀具，實現(xiàn)刀具回轉(zhuǎn)。 通過以上運動路線的分析，需要對直齒輪、錐齒輪、齒輪軸、帶傳動、鏈傳動、刀具、偏心輪連桿機(jī)構(gòu)分別設(shè)計。 關(guān)鍵詞： 外形；結(jié)構(gòu)；零件；設(shè)計
ABSTRACT:As the name implies, Qiecai machine is a kind of can be a variety of roots and leaves of vegetables cut into a variety of styles machine. The first design is the focus of many of its functions, its function is reflected in two aspects, one is able to cut the vegetable species, such as leaf vegetables in the cabbage, celery, cabbage, sauteed green beans, sweet beans, root vegetables, tomatoes, carrots, potatoes, garlic cucumber, onion can be cut; on the other hand reflected cut out diversified food type in the can, such as life in general need to use film, block, wire, strip, Ding, segment, the dishes can be realized on the machine. Another key is to achieve the decrease in volume and quality, design the reasonable internal structure is to reduce the volume and quality of the most important factors. The internal structure of the design framework Qiecai machine is as follows: firstly by the motor output power, and then through a simple stepless speed change mechanism, the mechanism is composed of main shaft of the motor through a belt drive two adjustable belt wheel, by adjusting the belt pulley wheel diameter to achieve the purpose of changing speed. The stepless speed change mechanism will power is divided into three parts, the first: stepless speed change mechanism is connected to the output shaft power output level; second: without extremely gearshift mechanism is connected with the output shaft power output level, through a set of standard straight bevel gear will transfer horizontal axial force to the vertical direction, and then drive the plane eccentric linkage reciprocating movement of the transfer to the vertical knife, reciprocating vertical knife; third: stepless speed change mechanism is connected with the output shaft, the output shaft is connected with a belt pulley, the belt transmission to transmit power to the centrifugal disc cutter, realize rotary cutting tool. Through the above analysis of the movement route, need to design the gear, bevel gear, gear shaft, chain drive,the eccentric wheel connecting rod mechanism.
