Description

一种无端部盲区小直径丝/棒/管材超声检测系统 技术领域
本发明涉及丝/棒/管材无损检测技术，提供一种无端部盲区小直径丝/棒/管材超声检测器及自动化超声无损检测系统。
背景技术
航空、航天、核工业、特种设备及医疗等领域，丝/棒/管材做为基本原料形式应用广泛，如果丝/棒/管材存在裂纹、夹杂等缺陷将严重影响产品的使用安全，造成严重的后果。超声检测方法一般是产品质量检测方法中规定的必须采用的方法之一，大批量检材的检测大都采用自动检测的方法。
目前所有的丝/棒/管材检测系统存在一个共性的问题，那就是端部盲区问题。设备制造标准YB4082规定：“管端不可探区域(端部盲区)不大于200mm”。检测方法标准GB5777规定：“自动检测时对钢管两端将不能有效地检验，此区域视为自动检测的盲区，制造方可采用有效方法来保证此区域质量”。针对端部检测盲区，丝/棒/管材的研制生产单位所采用的一种方法是将端部切除，这造成了原料的巨大浪费；另一种方法是靠制造工艺保证，这势必留下了安全隐患。
用于系统集成的超声检测器可分为超声探头机械旋转形式、超声相控阵电子旋转、多通道检测单元(ZL 2010 1 0146128.0)等形式。上述超声检测器都包括水耦合腔体和水耦合腔体两侧的耦合套，水腔体用于形成超声的耦合介质，两侧的耦合套用于检材的限位。在实际检测中，可以认为当检材位于两个耦合套之间时，检材与探头的相对位置是稳定的，可以获得可靠的超声信号。当检材的尾部离开尾部的耦合套时，检测与探头的相对位置就不能保证了，不能获得可靠稳定的超声信号，形成了端部检测盲区。也就是说两个耦合套间距的一半为端部检测盲区。超声探头机械旋转形式和超声相控阵电子旋转形式两种超声检测器一般尺寸较大，端部盲区也较大。OLYMPUS公司的BIS系统棒材检测系统，针对端部测试进行了优化设计，可获得非常短的端部不可测长度仍为20mm。ZL 2010 1 0146128.0中的多通道检测单元尺寸较小可大大缩小检材两端的检测盲区，就其原理而言，不能从根本上消除检测盲区。
在检材行进方面，检材进出大都采用滚轮摩擦驱动的方式。这种摩擦驱动的方式容易发生丢转或者打滑的情况，速度控制不够精准；不同直径的检材需要调整多个驱动轮的高度来保证对心性，操作过程繁琐，效率低。针对截面形状为非圆形的检材，如方棒、六棱棒等，需按规格设计制作对应滚轮，通用性较差。
本发明提供了一种无端部盲区小直径丝/棒/管材自动化超声无损检测系统，检材以夹持传送方式精准进入超声检测器，以高速夹持牵引方式高速通过超声检测器，升降式分选机构完成自动分选，能够有效消除检材始端和末端的检测盲区，实现高速自动化检测。

具体实施方式
实施例1
如图5所示，现有超声检测器中，超声探头与检材之间是在“开放”的水环境下耦合和传播的，当检材到达水耦合腔体中的无约束区域时，检材端部位置会不可避免的机械摆动，无法获得稳定的超声检测信号，无法实施有效的检测。
如图6所示为本发明所述直入式无盲区超声检测器的基本原理图，通过内核的设计使用，使得超声探头与检材之间是在“隔离”的环境下耦合和传播的，超声探头声束通过“声眼”进入检材，检材在内核的约束下稳定行进，即使在端部位置也会获得稳定的传输，获得稳定的超声检测信号。因此本发明实现了端部“无盲区”检测。
如图7、8所示，所述超声检测器3包括储水器31、封盖32、环形阵列单元安装架33、环形阵列检测单元34、水泵35、水循环输入输出36以及传感器37；其中，封盖32位于储水器31上面，封盖32上设有连接开口，用于引出外环阵列探头342和水泵35的连接端口；环形阵列单元安装架33以焊接的方式固定在储水器31底板上，水泵35通过螺纹连接固定在储水器31底板上，环形 阵列检测单元34通过螺丝连接至环形阵列单元安装架33上；水泵35通过导水管与水循环输入输出36的输入端相连，水循环输入输出36的输出端连接另一根导水管，以完成水循环系统的连接；传感器37安装在封盖32内检材进入一侧，用于定位检材的头部和尾部。
如图9所示，环形阵列检测单元34包括外环部分和内环部分，外环部分和内环部分通过进丝侧端盖345和出丝侧端盖346连接为一体；外环部分由外环基体341和按规律分布的外环阵列探头342构成，内环部分由内环内核343和内环内核锁紧环344构成。
所述外环基体341为圆环体，圆环外圆柱面按多列环状阵列结构分布探头安装孔，圆环内孔配合进丝侧端盖345和出丝侧端盖346形成耦合水腔；外环阵列探头342依次通过外环探头调节锁紧螺钉固定在探头安装孔中，探头的数量应确保检材的声覆盖；耦合水腔芯部放置内环内核343，内环内核343为圆筒形构件，其从进丝侧端盖345中心孔穿进，然后从出丝侧端盖346中心孔穿出，内环内核锁紧环344在进丝侧端盖345处将内环内核343锁紧固定；内环内核343沿外圆柱面按多列环状阵列结构分布孔型通孔——“声眼”，“声眼”与探头安装孔的孔轴线对应；内环内核343圆筒内孔为检材行走通道；超声束在耦合水腔内经过“声眼”到达检材表面，继而在检材内传播测试；内环内核343上方还分布有一系列孔型或条形“气眼”，“气眼”为1个直径3mm左右的通孔，位于耦合水腔中内环内核343的上方(即“气眼”为内环内核343筒壁上的通孔)，轴向位置位于检材进入方向且距离第1个声眼5mm以上的位置，用于检材行走通道内气体的排出。
所述外环基体341为由高密度有机玻璃材料制作的圆环体，内环内核343为由铜制成的圆筒形构件。

实施例5
对于检材直线传送的检测方式，为确保声束对检材的100％覆盖，需在有限的空间内实现多个探头布置。采用“外环-多环多个探头，内核-多环多个声眼”的理念。图10给出了“外环-4环16个探头，内核-4环16个声眼”的探头布置形式。依据声束覆盖要求，外环共布置4环探头，每环间隔90°分布4个探头。第一环探头分别为探头1-1，探头1-2，探头1-3和探头1-4，在内环内核343上对 应分布声眼1-1-1，声眼1-2-2，声眼1-3-3和声眼1-4-4。沿检材轴向方向按一定间距布置第二环探头，分别为探头2-1，探头2-2，探头2-3和探头2-4，内环内核343沿轴向方向对应分布四个声眼。依次类推，第三环探头分别为探头3-1，探头3-2，探头3-3和探头3-4，第四环探头分别为探头4-1，探头4-2，探头4-3和探头4-4，本实施例共布置4环16个探头，4环16个声眼，保证了检材的声束覆盖率。根据实际需要探头的数量可灵活采用“外环-N环M个探头，内核-N环M个声眼”的布置形式，实现直入传送方式无盲区检测。
