桁架机械手在机床生产线上的具体应用

发布日期:2018-02-07 作者:xiexiaoying.cn 点击:

桁架机械手作为时尚的一种输送工具,越来越受到青睐。目前,国内外主流的柔性自动线物流系统主要有两种形式:由桁架机械手输送工件组成的全自动生产系统和由机器人搬运系统进行上下料组成自动生产线。在欧美日等发达工业体系,由高速加工中心和桁架机械手组成的敏捷柔性生产系统已经是主流产品,桁架机械手在高空中输送零件,直接把被加工零件从一台机床输送到另一台机床上,桁架机械手兼有工序间运输和自动上下料及物料回转等辅助功能。由于它输送快捷、精准、柔性, 结构相对简捷,便于组合。因而,被机床制造商所器重。

桁架机械手的结构与工作原理

桁(heng)架机械手由(you)主(zhu)体(ti)、驱(qu)动(dong)系(xi)统和(he)控制系(xi)统三个基本部(bu)(bu)(bu)分组成。按机器(qi)人结(jie)构(gou)(gou)分类为(wei)直(zhi)角(jiao)(jiao)坐(zuo)标型(xing),机械手沿二维直(zhi)角(jiao)(jiao)坐(zuo)标系(xi)移动(dong)。主(zhu)体(ti)部(bu)(bu)(bu)分通(tong)常采(cai)用龙门(men)式(shi)结(jie)构(gou)(gou),由(you)y向(xiang)横(heng)(heng)(heng)梁(liang)与(yu)(yu)导轨、z向(xiang)滑(hua)(hua)枕(zhen)、十字滑(hua)(hua)座、立柱、过(guo)渡连(lian)接板和(he)基座等部(bu)(bu)(bu)分组成,z向(xiang)的(de)直(zhi)线运(yun)动(dong)皆为(wei)交流伺服电动(dong)机通(tong)过(guo)蜗轮减速(su)器(qi)驱(qu)动(dong)齿(chi)轮与(yu)(yu)y向(xiang)横(heng)(heng)(heng)梁(liang)、z向(xiang)滑(hua)(hua)枕(zhen)上固定(ding)的(de)齿(chi)条(tiao)作滚动(dong),驱(qu)动(dong)移动(dong)部(bu)(bu)(bu)件沿导轨快速(su)运(yun)动(dong)。移动(dong)部(bu)(bu)(bu)件为(wei)质量(liang)较轻(qing)的(de)十字滑(hua)(hua)座和(he)z向(xiang)滑(hua)(hua)枕(zhen),滑(hua)(hua)枕(zhen)采(cai)用由(you)铝合金(jin)拉制的(de)型(xing)材。横(heng)(heng)(heng)梁(liang)采(cai)用方钢型(xing)材,在(zai)(zai)横(heng)(heng)(heng)梁(liang)上安装有导轨和(he)齿(chi)条(tiao),通(tong)过(guo)滚轮与(yu)(yu)导轨接触,整(zheng)个机械手都悬挂在(zai)(zai)其上。

由(you)于(yu)桁(heng)架机(ji)械(xie)(xie)手输(shu)(shu)送(song)的(de)(de)(de)(de)(de)(de)速(su)度(du)(du)快(kuai),加速(su)度(du)(du)大(da),加减(jian)速(su)时间短。当(dang)输(shu)(shu)送(song)较重的(de)(de)(de)(de)(de)(de)工件时,惯量大(da),因(yin)此,伺服驱(qu)动(dong)(dong)(dong)电(dian)机(ji)要有(you)(you)(you)足(zu)够(gou)的(de)(de)(de)(de)(de)(de)驱(qu)动(dong)(dong)(dong)和制(zhi)动(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)能力,支(zhi)撑元(yuan)件也要有(you)(you)(you)足(zu)够(gou)的(de)(de)(de)(de)(de)(de)刚度(du)(du)及(ji)强度(du)(du)。只有(you)(you)(you)这(zhei)样,才能使伺服电(dian)动(dong)(dong)(dong)机(ji)满足(zu)桁(heng)架机(ji)械(xie)(xie)手输(shu)(shu)送(song)的(de)(de)(de)(de)(de)(de)高(gao)响应、高(gao)刚度(du)(du)及(ji)高(gao)精(jing)度(du)(du)要求。在选(xuan)择合适伺服电(dian)动(dong)(dong)(dong)机(ji)的(de)(de)(de)(de)(de)(de)情况下(xia),根据物(wu)料运(yun)(yun)动(dong)(dong)(dong)的(de)(de)(de)(de)(de)(de)距离(li)和运(yun)(yun)行(xing)(xing)节(jie)拍,计算出伺服系统(tong)的(de)(de)(de)(de)(de)(de)位移和轨迹,对(dui)驱(qu)动(dong)(dong)(dong)器(qi)PID参(can)数(shu)进行(xing)(xing)动(dong)(dong)(dong)态调整。桁(heng)架机(ji)械(xie)(xie)手根据接收到的(de)(de)(de)(de)(de)(de)位移、速(su)度(du)(du)指(zhi)令,经变(bian)化(hua)、放大(da)并调整处理后(hou),传(chuan)递给运(yun)(yun)动(dong)(dong)(dong)单元(yuan),通(tong)过(guo)光纤(xian)传(chuan)感器(qi)对(dui)运(yun)(yun)行(xing)(xing)状态进行(xing)(xing)实(shi)时检测,在高(gao)速(su)搬运(yun)(yun)过(guo)程中,运(yun)(yun)动(dong)(dong)(dong)部件在极短的(de)(de)(de)(de)(de)(de)时间内到达给定的(de)(de)(de)(de)(de)(de)速(su)度(du)(du),并能在高(gao)速(su)行(xing)(xing)程中瞬间准停,通(tong)过(guo)高(gao)分辩率绝对(dui)式编码器(qi)的(de)(de)(de)(de)(de)(de)插(cha)补(bu)运(yun)(yun)算,控制(zhi)机(ji)械(xie)(xie)误差和测量误差对(dui)运(yun)(yun)动(dong)(dong)(dong)精(jing)度(du)(du)的(de)(de)(de)(de)(de)(de)影响。由(you)于(yu)被输(shu)(shu)送(song)的(de)(de)(de)(de)(de)(de)工件不同(tong),质(zhi)量也不同(tong),因(yin)此,桁(heng)架机(ji)械(xie)(xie)手有(you)(you)(you)多种规格和系列(lie)。在选(xuan)择时,根据被输(shu)(shu)送(song)工件的(de)(de)(de)(de)(de)(de)质(zhi)量,加工的(de)(de)(de)(de)(de)(de)节(jie)拍来(lai)选(xuan)取。但机(ji)械(xie)(xie)手的(de)(de)(de)(de)(de)(de)手臂,夹(jia)持方(fang)式,则(ze)根据被输(shu)(shu)送(song)工件的(de)(de)(de)(de)(de)(de)形状、结构及(ji)机(ji)床夹(jia)具定夹(jia)方(fang)式来(lai)设(she)计(见图2)。

机(ji)(ji)械(xie)(xie)手(shou)(shou)能够借助可(ke)(ke)编程序来处(chu)理和(he)执(zhi)行(xing)任(ren)务。机(ji)(ji)械(xie)(xie)手(shou)(shou)主要(yao)由手(shou)(shou)图 1 臂、回转装置、运动(dong)部件(jian)及驱动(dong)部件(jian)组成。通过对工(gong)(gong)(gong)件(jian)外形(xing)或(huo)工(gong)(gong)(gong)件(jian)上定(ding)(ding)(ding)位支撑点定(ding)(ding)(ding)位夹(jia)持(chi)工(gong)(gong)(gong)件(jian)。例如,在汽车发动(dong)机(ji)(ji)加工(gong)(gong)(gong)柔性自动(dong)线物流输送中,桁架机(ji)(ji)械(xie)(xie)手(shou)(shou)的(de)(de)夹(jia)持(chi)模(mo)(mo)(mo)块(kuai)会根据(ju)缸体、缸盖、曲轴等工(gong)(gong)(gong)件(jian)的(de)(de)外形(xing)特点,选(xuan)取不同的(de)(de)定(ding)(ding)(ding)位和(he)夹(jia)持(chi)方式。柔性机(ji)(ji)械(xie)(xie)手(shou)(shou)上采用气(qi)缸和(he)电机(ji)(ji)进(jin)行(xing)定(ding)(ding)(ding)位和(he)夹(jia)持(chi)模(mo)(mo)(mo)块(kuai)的(de)(de)切换(huan)驱动(dong),一套(tao)机(ji)(ji)械(xie)(xie)手(shou)(shou)可(ke)(ke)完成不同品种的(de)(de)工(gong)(gong)(gong)件(jian)搬运工(gong)(gong)(gong)作。夹(jia)持(chi)定(ding)(ding)(ding)位模(mo)(mo)(mo)块(kuai)可(ke)(ke)根据(ju)产品质量和(he)外形(xing)的(de)(de)大小采用系列化设计(ji),机(ji)(ji)械(xie)(xie)手(shou)(shou)上的(de)(de)夹(jia)持(chi)定(ding)(ding)(ding)位模(mo)(mo)(mo)块(kuai)安装方式相同,针对不同系列的(de)(de)工(gong)(gong)(gong)件(jian),只需切换(huan)相应的(de)(de)夹(jia)持(chi)定(ding)(ding)(ding)位模(mo)(mo)(mo)块(kuai)即可(ke)(ke),满足快速切换(huan)的(de)(de)需要(yao)。这样,当加工(gong)(gong)(gong)不同品种的(de)(de)工(gong)(gong)(gong)件(jian),只须变换(huan)夹(jia)持(chi)模(mo)(mo)(mo)块(kuai)就可(ke)(ke)实现,提高(gao)了桁架机(ji)(ji)械(xie)(xie)手(shou)(shou)的(de)(de)柔性化。

上述提(ti)及(ji)的只(zhi)是(shi)数量上的比较,其实真正的原因还是(shi)国(guo)产(chan)(chan)(chan)桁架(jia)机(ji)械手(shou)的技(ji)术(shu)水平与国(guo)外有着一定的差距(ju)。柔性(xing)加(jia)工自(zi)动线采用的桁架(jia)机(ji)械手(shou),也是(shi)从国(guo)外进口的桁架(jia)机(ji)械手(shou)。那时,国(guo)内还没有专(zhuan)门生产(chan)(chan)(chan)桁架(jia)机(ji)械手(shou)的厂家。如(ru)今,国(guo)内巨一等(deng)一些桁架(jia)机(ji)械手(shou)生产(chan)(chan)(chan)厂家的涌出,为国(guo)产(chan)(chan)(chan)柔性(xing)加(jia)工自(zi)动线带来了(le)希望,进而缩小了(le)与国(guo)外在生产(chan)(chan)(chan)桁架(jia)机(ji)械手(shou)方面(mian)的差距(ju),国(guo)产(chan)(chan)(chan)桁架(jia)机(ji)械手(shou)在柔性(xing)加(jia)工自(zi)动线的应用也越来越多,从而打破国(guo)产(chan)(chan)(chan)市场(chang)被外国(guo)人的垄断。

桁架机械手作为柔性输送系统,已成为柔性加工自动线中的重要组成部分,过去未采用桁架机械手输送的自动线中的输送部分称之为输送带或输送装置。而今,用了桁架机械手则称之为输送系统或物流系统。过去的输送带由机床生产厂自己生产,而今则由外部专业生产厂来提供;过去的输送带驱动或是用一个油缸,或是减速机通过链条或机动辊子驱动,各个动作单独来完成,所用时间较长且位置精度较差,而今则由伺服系统驱动,完成多个坐标的复合运动,所用时间短, 效率高, 且运动位置精准。这些的进步,都缘于技术水平的提高,解决了桁架机械手的关键技术及难点技术。相信,随着国产桁架机械手技术水平的不断提高,桁架机械手在柔性加工自动线上的应用会越来越多,采用桁架机械手的柔性加工自动线将会成为今后的一大卖点,市场前景非常可观,从而带动国产柔性加工自动线有一个质的飞跃。
