Description

一种确定被测物电磁性能的测试装置 技术领域
本发明涉及天线测试技术领域，更具体地说，它涉及一种确定被测物电磁性能的测试装置。
背景技术
在对天线的电磁性能进行测试时，需要对被测物进行多个位点的检测，测试出多组数据从而可以更加全面的反映出被测物的电磁性能，为了提高检测结果的精确度，通常采用过采样的方式对被测物进行检测。众所周知，作为平面近场扫描，为了有效推导出一定范围内的远场，必须在整个平面内采样，并且必须满足采样点间距L<lambda/2,其中lambda为辐射信号的波长；而目前过采样的方法只在球面近场中普遍使用，在平面近场测试中还没有使用过采样技术。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种确定被测物电磁性能的测试装置，具有能够实现数据过采样的优点。
本发明的上述技术目的是通过以下技术方案得以实现的：一种确定被测物电磁性能的测试装置，包括载物台和支架，所述支架包括设置在所述载物台两侧的立架和滑移连接于所述立架且能够形成覆盖所述载物台的滑移面的滑移杆，沿所述滑移杆的轴线方向设有多个探头；还包括用于驱动所述滑移杆沿所述立架移动的横向驱动装置和用于驱动多个所述探头同时沿所述滑移杆的轴线方向移动的轴向驱动装置。
通过采用上述技术方案，测试时，先将被测物放置在载物台上，启动测试装置，通过探头对被测物进行探测，多个探头可以对被测物的多个位点进行探测，当滑移杆位于某一位置测得一组数据后，通过横向驱动装置驱动滑移杆移动一段距离，探头也随之移动一段距离，即可得出第二组数据，以此类推，将滑移杆由被测物的一侧移动至另一侧后，即可形成一组覆盖整个被测物并呈矩阵形式分布的数据点；随后通过轴向驱动装置，驱动多个探头同时沿着滑移杆的轴线方向移动一段距离，即可对前次未检测到的部分进行再次检测，将滑移杆重新由被测物的一侧移动至另一侧，即可形成另一组覆盖整个被测物并呈矩阵形式分布的数据点；通过横向驱动装置和轴向驱动装置，对多个探头的检测位置进行调节，从而形成多组覆盖被测物并呈矩阵形式分布的数据组，实现了对被测物的过采样，采样过程更加简单方便，采样的数据点分布的更加密集，检测结果更加可靠。
本发明进一步设置为：所述横向驱动装置包括固定于所述立架的第一驱动电机、固定在所述第一驱动电机转轴上的主动轮、转动连接在所述立架上的从动轮、以及套设于所述主动轮和从动轮且固定于所述滑移杆的传送带。
通过采用上述技术方案，启动第一驱动电机，即可带动传送带移动，由于滑移杆固定在传送带上，滑移杆可以随着传送带沿着立架往复滑移，从而形成覆盖整个在载物台的滑移面，探头即可形成对被测物呈矩形阵列分布的检测位点；而且通过传送带的形式驱动滑移杆滑移，其占用体积小，传送距离大，成本低。
本发明进一步设置为：所述滑移杆包括外杆、滑动套接在所述外杆内用于固定多个所述探头的内杆、以及开设在所述外杆上供所述探头滑移的滑槽。
通过采用上述技术方案，滑动内杆即可带动多个探头同时移动，调节探头的过程简单方便。
本发明进一步设置为：所述轴向驱动装置包括固定于所述外杆的第二驱动电机、固定在所述第二驱动电机的转轴上的驱动齿轮、以及固定于所述内杆且与所述驱动齿轮相啮合的驱动齿条。
通过采用上述技术方案，启动驱动电机，即可带动驱动齿轮转动，在驱动齿轮与驱动齿条的啮合作用下，即可使内杆沿着外杆的轴线方向往复滑移。
本发明进一步设置为：所述立架上位于靠近所述主动轮和所述从动轮的位置设有用于限制滑移杆的定位块。
通过采用上述技术方案，由于滑移杆通过传送带的驱动进行滑移，在滑移至主动轮和从动轮的位置时，易出现滑移杆抵触在主动轮和从动轮上，从而造成主动轮和从动轮的损伤，通过设置定位块，滑移杆移动至极限位置时与定位块相抵触，从而使滑移杆不会与主动轮和从动轮发生刚性接触，减少了滑移杆对主动轮和从动轮的损伤。
本发明进一步设置为：所述定位块上位于面向所述滑移杆的一侧设有能够抵触于所述滑移杆的弹性减震件。
通过采用上述技术方案，弹性减震件可以减少滑移杆直接撞击定位块而导致滑移杆和定位块损伤的现象发生。
本发明进一步设置为：所述滑移杆上设有用于限制所述内杆滑移距离的限位组件。
通过采用上述技术方案，减少了位于最外侧的探头在内杆滑移的过程中撞击到立架上而造成探头损坏的现象发生。
本发明进一步设置为：所述限位组件包括开设在所述外杆上的安装槽、滑动连接在所 述安装槽内限位块、形成于所述限位块上面向所述立架一侧的滑移斜面、两端分别固定于所述限位块和所述安装槽底壁且始终处于压缩状态的第一弹性件、以及开设在所述内杆上的限位槽，且当位于最外侧的所述探头靠近所述立架时，所述限位块嵌入所述限位槽内。
通过采用上述技术方案，内杆在正常的滑移距离内滑移时，限位块受内杆的抵触被压缩在安装槽内，当内杆滑移至限位槽与限位块相对齐时，限位块受第一弹性件的弹性力作用而嵌入限位槽内，从而使内杆无法继续向前移动，使探头不会撞击到立架上；而由于在限位块上面向立架的一侧设有滑移斜面，内杆可以反向滑移而时限位块脱离限位槽，从而不会影响内杆在正常滑移距离内滑移。
本发明进一步设置为：所述限位组件包括固定在所述内杆上位于靠近最外侧的所述探头处且穿过所述滑槽的限位凸起。
通过采用上述技术方案，当内杆滑移至探头靠近立架时，限位凸起可以抵触在立架上，从而限制内杆继续向前移动，使探头不会撞击到立架上。
本发明进一步设置为：所述限位凸起面向所述立架的一侧固定有能够抵触于所述立架的第二弹性件。
通过采用上述技术方案，第二弹性件减少了限位凸起与立架之间发生刚性接触而造成限位凸起和立架损伤的现象发生。
综上所述，本发明具有以下有益效果：
其一，通过横向驱动装置和轴向驱动装置，对多个探头的检测位置进行调节，从而形成多组覆盖被测物并呈矩阵形式分布的数据组，实现了对被测物的过采样，采样过程更加简单方便，采样的数据点分布的更加密集，检测结果更加可靠；
其二，滑移杆由外杆和滑动套接于外杆的内杆组成，从而滑移内杆即可实现探头的同时滑移，探头调节的过程简单方便；
其三，设置定位块和弹性减震件，减少了主动轮、从动轮和滑移杆的损伤；
其四，设置限位组件，减少了位于最外侧的探头在内杆滑移的过程中撞击到立架上而造成探头损坏的现象发生。

如图1所示，支架3包括设置在载物台2两侧的立架31和滑动连接在立架31上的滑移杆32，立架31焊接在箱体1底部的竖杆311和焊接竖杆311上的横杆312组成，在横杆312上开设有供滑移杆32滑移的槽口，在滑移杆32的两端通过螺钉固定有滑块，滑块嵌入槽口内，从而形成了滑移杆32与横杆312的滑动连接，滑移杆32位于载物台2的正上方，且滑移杆32自横杆312的一端滑移至另一端时可以形成覆盖整个载物台2的滑移面；
如图2所示，滑移杆32包括外杆321和滑动套接于外杆321的内杆322，在内杆322上固定有多个探头4，多个探头4沿内杆322的轴线方向均匀分布，且在外杆321上开设有供探头4滑移的滑槽323，探头4穿过滑槽323且竖直朝下，从而对被测物进行检测；内杆322上通过卡嵌的方式固定有多个射频接口，射频接口沿内杆322的轴线方向均匀分布，探头4插接在射频接口内，从而实现了与射频接口的固定和电性连接。
如图3和图4和图5所示，在立架31上设有用于驱动滑移杆32沿横杆312滑移的横向驱动装置，横向驱动装置包括第一驱动电机51、主动轮52、从动轮53和传送带54；在横杆312上且靠近横杆312的一端开设有固定槽，第一驱动电机51嵌设在固定槽内，且通过螺 栓固定在横杆312上，第一驱动电机51采用伺服电机；主动轮52上开设有固定孔，主动轮52套设在第一驱动电机51的转轴上，从动轮53转动连接在横杆312的另一端；传送带54套设于主动轮52和从动轮53，并处于绷紧的状态，从而实现了动力传输的功能，滑移杆32的一端通过螺栓固定有连接板，连接板与传送带54通过螺钉紧固在一起，从而传送带54在移动的过程中可以带动滑移杆32同时移动。
如图4所示，为了防止滑移杆32与主动轮52和从动轮53发生碰撞，在横杆312上位于靠近主动轮52和从动轮53的位置焊接有定位块7，在定位块7朝向滑移杆32的一侧表面上焊接有弹性减震件71，弹性减震件71采用弹簧，当滑移杆32滑移至靠近主动轮52和从动轮53的位置时，弹性减震件71抵触在滑移杆32上，从而减少滑移杆32直接撞击主动轮52和从动轮53而导致滑移杆32、主动轮52和从动轮53损伤的现象发生。
如图3和图6所示，在立架31上还设有用于驱动内杆322沿外杆321的轴线方向滑移的轴向驱动装置6，轴向驱动装置6包括固定在外杆321上的第二驱动电机61、固定在第二驱动电机61的转轴上的驱动齿轮62、以及固定在内杆322上且与驱动齿轮62相啮合的驱动齿条63；第二驱动电机61采用伺服电机，并通过螺栓固定在外杆321的上表面；在外杆321的上表面上开设有贯穿外杆321的通槽，驱动齿条63焊接在内杆322上且穿过通槽，且驱动齿条63可以在通槽内往复滑移，从而驱动电机带动驱动齿条63滑移时即可带动内杆322在外杆321内滑移。
如图7和图8所示，为了防止位于最外侧的探头4在内杆322滑移的过程中撞击到立架31，在滑移杆32上设有用于限制内杆322滑移距离的限位组件，限位组件包括开设在外杆321上的安装槽81、滑动连接在安装槽81内限位块82、形成于限位块82上面向立架31一侧的滑移斜面83、两端分别固定于限位块82和安装槽81底壁且始终处于压缩状态的第一弹性件84、以及开设在内杆322上的限位槽85，限位块82呈楔形，限位槽85为与限位块82相配合的楔形槽，且当位于最外侧的探头4位于靠近立架31的位置时，限位块82能够嵌入限位槽85内，第一弹性件84采用弹簧；
内杆322在正常的滑移距离内滑移时，限位块82受内杆322的抵触被压缩在安装槽81内，当内杆322滑移至限位槽85与限位块82相对齐时，限位块82受第一弹性件84的弹性力作用而嵌入限位槽85内，从而使内杆322无法继续向前移动，使探头4不会撞击到立架31上；而由于在限位块82上面向立架31的一侧设有滑移斜面83，内杆322可以反向滑移而时限位块82脱离限位槽85，从而不会影响内杆322在正常滑移距离内滑移。
测试时，先将被测物放置在载物台2上，启动测试装置，通过探头4对被测物进行探 测，多个探头4可以对被测物的多个位点进行探测，当滑移杆32位于某一位置测得一组数据后，启动第一驱动电机51驱动滑移杆32移动一段距离，探头4也随之移动一段距离，即可得出第二组数据，以此类推，将滑移杆32由被测物的一侧移动至另一侧后，即可形成一组覆盖整个被测物并呈矩阵形式分布的数据点；随后启动第二驱动电机61，驱动内杆322沿外杆321的轴线方向滑移一段距离，即带动多个探头4同时沿着外杆321的轴线方向移动，即可对前次未检测到的部分进行再次检测，将滑移杆32重新由被测物的一侧移动至另一侧，即可形成另一组覆盖整个被测物并呈矩阵形式分布的数据点；通过横向驱动装置和轴向驱动装置6，对多个探头4的检测位置进行调节，从而形成多组覆盖被测物并呈矩阵形式分布的数据组，实现了对被测物的过采样，采样过程更加简单方便，采样的数据点分布的更加密集，检测结果更加可靠。
实施例二：一种确定被测物电磁性能的测试装置，如图9和图10所示，与实施例一的不同之处在于，限位组件包括固定在内杆322上的限位凸起86，限位凸起86位于靠近最外侧的探头4处且穿过滑槽323向下延伸；为了减少了限位凸起86与立架31之间发生刚性接触而造成限位凸起86和立架31损伤的现象发生，在限位凸起86面向立架31的一侧固定有第二弹性件87，第二弹性件87采用弹簧，且第二弹性件87与横杆312相对齐，从而位于最外侧的探头4位于靠近立架31的位置时，第二弹性件87能够抵触在横杆312上；
内杆322在正常的滑移距离内滑移时，限位凸起86和第二弹性件87不会与横杆312相接触，当内杆322滑移至位于最外侧的探头4靠近立架31时，第二弹性件87抵触在横杆312上，从而使内杆322无法继续向前移动，即探头4不会撞击到立架31上。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
