The invention discloses a scanning tool for phased array nondestructive testing of a flat plate piece, which comprises a pushing trolley walking on the flat plate piece, and two clamping devices are transversely arranged in the advancing direction of the pushing trolley, wherein each clamping device comprises a clamping jaw, a stress shell, a sliding rod and a telescopic limiting mechanism. The stress shell is fixed to the pushing trolley, the sliding rod vertically penetrates through the stress shell, the lower end of the sliding rod is fixed to the clamping jaws, the upper end of the slidingrod is limited by a telescopic limiting mechanism arranged on the stress shell, the two clamping devices are opposite, the probe is clamped by the two clamping jaws, and the surface of the probe makes parallel contact with the surface of the flat plate piece. The scanning tool is used for phased array nondestructive testing of flat plates. The surface of the probe is uniformly stressed, the detection state that the surface of the probe is tightly attached to the surface of the flat plate piece can be kept, the surface defects of the flat plate piece can be accurately positioned, local abrasion caused by local interference friction generated in uneven areas of the surface of the probe and the surface of the flat plate piece can be prevented, and detection accuracy and detection efficiencyare improved.
本发明公开了一种用于平板件相控阵无损检测的扫查工装,包括在平板件上行走的推行小车,推行小车的前行方向上横向设置有两个夹持装置;夹持装置包括夹爪、受力外壳、滑杆、伸缩限位机构,受力外壳与推行小车固定,滑杆竖向穿设于受力外壳,滑杆的下端与夹爪固定,上端受限于设置在受力外壳上的伸缩限位机构,两个夹持装置相对,探头被两个夹爪夹紧,探头表面与平板件表面平行接触。该扫查工装用于平板件相控阵无损检测,探头表面受力均匀,既能保持探头表面与平板件表面紧密贴合的检测状态,准确定位平板件表面缺陷,又能防止探头表面与平板件表面的不平整区域产生局部过盈摩擦造成局部磨损,提高了检测准确率和检测效率。
