style="text-indent:25px">刨削加工,以往采用**刨夾具而依靠操作者調(diào)節(jié)墊鐵壓板來達(dá)到加工要求,不但調(diào)節(jié)費(fèi)時(shí),而且加工質(zhì)量不穩(wěn)定,常因刨削質(zhì)量不佳,將零件送回退刨。為此設(shè)計(jì)制造了適合于加工下工作臺的**刨夾具,這樣能穩(wěn)定加工質(zhì)量,提高生產(chǎn)效率。刨夾具是由5個(gè)**部分組成,直接安裝在龍門刨床的工作臺面上,相當(dāng)于5套墊鐵。位于距離零件端面2/9L位置的二套墊鐵作主要定位支承一套墊鐵有2個(gè)固定支承點(diǎn),另一套墊鐵有相當(dāng)于1個(gè)固定支承點(diǎn)的一對浮動(dòng)支承點(diǎn),因而符合三點(diǎn)定位的原則。二端和中間墊鐵作輔助支承,其數(shù)量可按零件的長短而增減,適當(dāng)選擇輔助支承墊鐵的數(shù)量和間隔可滿足不同長度零件的加工要求。二端輔助墊鐵帶有壓板座,對工作進(jìn)行壓緊。這種壓緊方式的優(yōu)越性在于壓板的位置浮動(dòng),零件被夾緊時(shí)不產(chǎn)生變形,因而適合于精加工和零件夾緊點(diǎn)比較薄的場合。上海坐標(biāo)磨床價(jià)格對于普通的基型系列我們可以把磨床分成外圓和內(nèi)圓兩種不同的類型。</p><div

style="text-indent:25px">內(nèi)圓磨床用于磨削各種圓柱孔(通孔、盲孔、階梯孔和斷續(xù)表面的孔等)和圓錐孔,某些內(nèi)圓磨床還附有磨削端面的磨頭。內(nèi)圓磨床主要類型有普通內(nèi)圓磨床、無心內(nèi)圓磨床和行星式內(nèi)圓磨床。普通內(nèi)圓磨床采用縱磨法和切入磨法磨削內(nèi)孔。采用專門的端磨裝置,可在工件一次裝夾中磨削內(nèi)孔和端面。無心內(nèi)圓磨床適于加工外圓表面已經(jīng)精加工的薄壁工件,如軸承環(huán)等。無心外圓磨床進(jìn)行磨削時(shí),工件放在砂輪與導(dǎo)輪之間,且工件中心高于砂輪和導(dǎo)輪中心連線,以被磨削外圓表面作定位基準(zhǔn),支承在托板上。無心外圓磨床生產(chǎn)率較高,加工精度好,但只能磨削連續(xù)外圓表面,且磨床調(diào)整費(fèi)時(shí),只適用于成批及大量生產(chǎn)中。</p><p style="text-indent:25px">近年來,普通磨床的自動(dòng)化程度在不斷提高。自動(dòng)化的措施有自動(dòng)進(jìn)給、砂輪的自動(dòng)修整和補(bǔ)償、自動(dòng)分度、自動(dòng)裝卸料及其自動(dòng)測量等。應(yīng)用于中、小批生產(chǎn)的磨床,其自動(dòng)化的凸顯趨勢是向數(shù)控磨床及適應(yīng)控制磨削方向發(fā)展。目前,對磨削加工精度和表面質(zhì)量要求愈來愈高。為了達(dá)到高精度及高表面質(zhì)量的要求,在機(jī)床結(jié)構(gòu)中采取了一系列提高精度和抗振性的措施。其中主要的措施有:采用高剛度及高旋轉(zhuǎn)精度的新型主軸軸承:提高整機(jī)及主要部件的動(dòng)態(tài)特性,尤其是動(dòng)剛度以及靜剛度:采用精密微量進(jìn)給機(jī)構(gòu):嚴(yán)格控制機(jī)床的熱變形,隔絕各種振源,采用各種高精度的自動(dòng)測量裝置以及高效率的冷卻液凈化裝置等。隨著高精度、高硬度機(jī)械零件數(shù)量的增加，磨床的性能、品種和產(chǎn)量都在不斷的提高和增長。</p><div
