【正文】 床是許多學(xué)校機(jī)械加工實(shí)習(xí)所用的設(shè)備，該產(chǎn)品是由前蘇聯(lián)鉆床型號(hào)改制而成，已有三十多年的歷史，但近年來(lái)，該型號(hào)鉆床的生產(chǎn)率降低，經(jīng)濟(jì)效益較低，同時(shí)伴有工人勞動(dòng)強(qiáng)度的增大，致使鉆床的使用率下降，經(jīng)調(diào)查分析，主要原因是該產(chǎn)品沒(méi)有自動(dòng)升降系統(tǒng)所致。同時(shí)針對(duì)其在實(shí)際使用過(guò)程中出現(xiàn)的一些問(wèn)題，并在理論分析與計(jì)算的基礎(chǔ)上，將其手動(dòng)升降變?yōu)樽詣?dòng)升降，然后制定出合理的傳動(dòng)方案，且選擇合適的原動(dòng)機(jī)作為它的動(dòng)力源，使改進(jìn)后的升降系統(tǒng)具有手動(dòng)和自動(dòng)升降并存的功能。 intensity during the production. By the research analysis, the reduction of Z32K is because this product has shortage on the automatic lifting system. In order to improve the efficiency of Z32K, the lifting systems of Z32k radial drilling machine will be primarily planed to promote in this time of design. Meanwhile, the main transmission parts of the drilling are going to be reunified. To some problems which occur in actual use, and on the basis of theoretical analysis and calculation, there will develop a proposal to change manual lift to automatic lift. then make the transmission scheme reasonable, and choose the appropriate engine as the power source of the gearbox, and the lifting of the improved system has manual and automatic lifting the coexistence of function.
