摘要
現(xiàn)在，碼坯機(jī)主要由切條機(jī)、切坯機(jī)、分坯機(jī)、夾盤機(jī)構(gòu)、行走機(jī)構(gòu)、升降機(jī)構(gòu)、旋轉(zhuǎn)機(jī)構(gòu)和電氣系統(tǒng)等組成。其中升降機(jī)構(gòu)是其中一個(gè)重要部分，現(xiàn)在升降機(jī)構(gòu)一般采用液壓升降與滾子鏈升降兩種方法。液壓升降因?yàn)橐簤涸闹圃炀纫筝^高、價(jià)格較貴，而且不能得到嚴(yán)格的傳動(dòng)比、效率較低。又由于工作性能易受到溫度變化的影響，因此不宜在很高或很低的溫度條件下工作，所以設(shè)計(jì)采用滾子鏈升降。因?yàn)樾凶邫C(jī)構(gòu)與升降機(jī)構(gòu)一體，所以一起設(shè)計(jì)了。升降采用滾子鏈，使其運(yùn)動(dòng)準(zhǔn)確，避免打滑現(xiàn)象，同時(shí)利用四個(gè)導(dǎo)向柱，增加設(shè)備的穩(wěn)定性。滾子鏈由大小鏈輪帶動(dòng)，共四組，布于四周，通過(guò)擺線針輪減速機(jī)通過(guò)齒輪箱帶動(dòng)兩根軸實(shí)現(xiàn)同步上升。最后在車架兩端加上配重，通過(guò)鋼絲繩與夾盤機(jī)構(gòu)連接，這樣可以減輕滾子鏈?zhǔn)芰?，減小功率。行走機(jī)構(gòu)通過(guò)另一擺線針輪減速機(jī)帶動(dòng)行走軸行走。此為本文設(shè)計(jì)方案，并且通過(guò)計(jì)算，論證了該設(shè)計(jì)方案的可行性。

Abstract
Now, setting machine is mainly composed of a cutting machine, cutting machine, cutter, chuck mechanism, running mechanism, lifting mechanism, a rotating mechanism and electrical system. The lifting mechanism is one of the most important parts, now lifting mechanism generally adopt hydraulic lifting and roller chain lifting two methods. Hydraulic lift for hydraulic components of the manufacturing precision is high, the price is more expensive, but can not be a strict transmission ratio, low efficiency. Because the working performance are susceptible to the influence of temperature change, therefore not at very high or very low temperature conditions, so the design of the roller chain lifting. Because the running mechanism and the lifting mechanism is integrated, so got together to design. Lifting the roller chain, the motion accuracy, avoid the slip phenomenon, at the same time using four guide posts, increases the stability of equipment. Roller chain sprocket drive by size, a total of four groups, the cloth around, through the cycloidal pinwheel speed reducer through the gear box drives two axis synchronous rise. In the final frame ends with counterweight, through the steel wire rope and the chuck body connected, this can reduce roller chain stress, reduce power. Walking mechanism through another cycloid reducer drive shaft walk walking. This is the design, and through calculation, it proves the feasibility of design scheme.
Key words :Setting machine; lifting mechanism; running mechanism; the roller chain lifter
