【文章內(nèi)容簡介】 體上下。材料：45號(hào)鋼。圖310調(diào)整螺桿機(jī)構(gòu)如圖311所示，圖示列出了張緊裝置松弛和張緊兩個(gè)狀態(tài)。在松弛狀態(tài)下順時(shí)針轉(zhuǎn)動(dòng)把手90176。，中間的旋轉(zhuǎn)塊推動(dòng)伸臂，使兩個(gè)輪中心距擴(kuò)大，達(dá)到張緊砂帶的效果。圖311張緊裝置設(shè)計(jì)旋轉(zhuǎn)塊的推動(dòng)部分采用半圓柱狀，方便推動(dòng)伸臂，而伸臂對(duì)應(yīng)位置設(shè)置了圓弧卡槽，在伸臂旋轉(zhuǎn)90176。之后，能后卡在卡槽內(nèi)不會(huì)輕易彈出。圖311張緊裝置設(shè)計(jì)如圖312所示，方便兩邊工人控制機(jī)器，可操作機(jī)器傾斜90度。圖312扶手設(shè)計(jì)如圖313所示，采用凹形結(jié)構(gòu)，形狀與鋼軌輪廓相似以減少砂帶在打磨過程中的變形次數(shù)，提高壽命，硬度在4070HS(A)之間。圖313行走輪設(shè)計(jì).如圖314所示，利用位移傳感器。該位移傳感器是一種屬于金屬感應(yīng)的線性器件，接通電源后，在開關(guān)的感應(yīng)面將產(chǎn)生一個(gè)交變磁場，當(dāng)接觸輪出下降接近此感應(yīng)面時(shí)，金屬中則產(chǎn)生渦流而吸取了振蕩器的能量，使振蕩器輸出幅度線性衰減，然后根據(jù)衰減量的變化來完成無接觸檢測其豎直位移的目的。圖314電子數(shù)字顯示裝置如圖315所示，類似彈簧測力計(jì)原理，套筒內(nèi)裝有彈簧與升降裝置相連，彈簧處于自然狀態(tài)時(shí)使機(jī)械數(shù)字顯示裝置顯示零刻度。當(dāng)升降裝置升降時(shí)，彈簧受力發(fā)生形變，其形變量通過數(shù)學(xué)換算等量換算成升降裝置的位移量。圖315機(jī)械數(shù)字顯示裝置設(shè)計(jì)第四章 整體工程圖和主要零件零件圖注：由于篇幅限制所有詳細(xì)工程圖見附錄1.主動(dòng)軸第五章 典型結(jié)構(gòu)零部件的工藝設(shè)計(jì)注：由于篇幅限制所有零部件詳細(xì)工藝圖表見附錄2.第六章 典型結(jié)構(gòu)零部件的數(shù)控加工程序設(shè)計(jì)一、工作軸O0000(PROGRAM NAME ____________________________1)(DATE=DDMMYY 190716 TIME=HH:MM 13:09)(MCX FILE C:\USERS\ASUS\DESKTOP\工件車\)(NC FILE D:\MASTERCAM\LATHE\NC\)(MATERIAL ALUMINUM MM 2024)G21(TOOL 1 OFFSET 1)(OD ROUGH RIGHT 80 DEG.
