可选地，定位凹槽520的截面可呈V字形（三角形）或梯形等合适形状。
具体应用中，换能器载板52可以根据换能器的大小、结构、形状变更修改，以达到良好的夹持效果。
可选地，如图1至图7所示，进给组件60包括导轨62、前板61、后板63和调节螺旋杆64，导轨62可以设置有两根，且导轨62滑动穿过于机架10，即导轨62滑动连接于机架10且可以沿机架10滑动而靠近或远离反射板70，前板61的两端连接于两根导轨62的前端，后板63的两端连接于两根导轨62的后端，前板61、后板63。调节螺旋杆64螺纹连接于机架10，且调节螺旋杆64的前端接触于或靠近于前板61，调节螺旋杆64的后端接触于或靠近于后前板61。通过旋转调节螺旋杆64，可以驱动导轨62、前板61、后板63及定位组件50、超声换能器前进或后退。
可选地，导轨62或前板61的前端设置有用于定位定位组件50的台阶凹槽610，台阶凹槽610处设置有螺纹孔611。定位组件50可以精准固定于台阶凹槽610处。
可选地，机架10包括底板1、左侧立板2和右侧立板3，左侧立板2和右侧立板3连接于底板1且相向设置，回波反射部件470（扭转组件40的基板401）连接于左侧立板2，超声换能器进给部件560连接于右侧立板3。回波反射部件470可以固定连接于左侧立板2，右侧立板3可以设置有用于导轨62穿过的滑动通孔301，进给组件60连接于右侧立板3。即调节螺旋杆64螺纹穿过于右侧立板3的螺纹通孔302，两根导轨62滑动穿过于右侧立板3。
本实施例中，其中底板1可为矩形平板，并设置有螺纹孔，用于连接左侧立板2和右侧立板3。右侧立板3上设置螺纹孔611，用于调节螺旋杆64衔接，使调节螺旋杆64可以通过旋转相对右侧立板3左右移动，右侧立板3设置有2个通孔，用于与导轨62配合，使导轨62可以相对右侧立板3左右移动。
本发明实施例所提供的一种用于超声换能器回波测试的测试装置，换能器载板52和进给组件60通过简单结构实现前进后退功能，可靠性佳，且扭转组件40可以相对换能器载板52实现多角度回波反射，确保可以找到回波峰值所正对角度。换能器载板52可装载多个换能器，同时测量，方便实时对比，测试效率高。
本发明实施例还提供了一种用于超声换能器回波测试的测试方法，采用上述的一种用于超声换能器回波测试的测试装置，包括以下步骤：
将待测试的超声换能器通过定位组件50固定于进给组件60；
通过进级组件调整超声换能器与回波反射部件470中反射板70的距离；
通过回波反射部件470中的扭转组件40调整反射板70的姿态；
通过回波接收器找到回波峰值并记录回波峰值。
具体应用中，超声换能器可为毫米级的超声换能器，其可由换能器载板52和换能器夹紧板51夹持定位，且换能器载板52上设置有定位凹槽520，可以先将超声换能器放置于定位凹槽520，再通过螺丝将换能器夹紧板51锁紧于换能器载板52上，使超声换能器被夹紧于定位凹槽520内。
具体应用中，当调节螺旋杆64左移时，调节螺旋杆64的前端会顶着前板61，带动整个进给组件60和定位组件50、超声换能器向左移动，从而靠近回波反射部件470；当调节螺旋杆64右移时，调节螺旋杆64的后端会顶着后板63，带动整个进给组件60和定位组件50、超声换能器向右移动，从而远离回波反射部件470。
具体应用中，基板401可以通过螺钉固定在左侧立板2上，一级调节板402可以通过转动基板401上的第一调节旋钮41相对基板401在垂直方向上沿圆弧做弧向转动；二级调节板403可以通过转动一级调节板402上的第二调节旋钮42相对一级调节板402在水平方向上沿圆弧做弧向转动。反射板70可以通过螺钉连接在二级调节板403上，随扭转组件40的转动而转动。

以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换或改进等，均应包含在本发明的保护范围之内。
