Description

Handheld nondestructive testing machine Technical Field The utility model relates to the technical field of nondestructive testing, in particular to a handheld nondestructive testing machine. Background The ultrasonic flaw detector pipeline weld joint flaw detection GUT36 nondestructive flaw detection is a testing means for detecting the surface and internal quality of a detected part on the premise of not damaging the working state of a workpiece or raw materials. Flaw detectors are of a wide variety, but in the actual flaw detection process, pulse-reflection ultrasonic flaw detectors are most widely used. In a uniform material, the presence of defects will generally cause material discontinuities which in turn tend to cause acoustic impedance inconsistencies, and it is known by the reflection theorem that ultrasonic waves will reflect at the interface between two media of different acoustic impedance, the amount of energy reflected being related to the difference in acoustic impedance of the media across the interface and the orientation and size of the interface. Pulse-reflex ultrasonic flaw detectors are designed according to this principle. For example, the ultrasonic flaw detector pipeline weld joint flaw detection GUT36 needs to be used by holding the host computer with one hand and holding the ultrasonic probe with the other hand, however, when in use, the user needs to operate the host computer, which results in the inconvenience of the user needing to operate with fingers on the hand holding the host computer. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a handheld nondestructive testing machine, which solves the problems in the background art. The handheld nondestructive testing machine comprises a chest hanger, wherein one side of the chest hanger is fixedly connected with a support column, a first ball screw is rotationally connected inside the support column, bearings are arranged at two ends of the support column, the outer side of the first ball screw is in threaded connection with a pushing column, one end of the pushing column extends to the outer side of the support column and is fixedly connected with two side plates, bearings are arranged on one side of each side plate, rotating shafts are arranged inside the bearings, a mounting plate is fixedly connected between the two rotating shafts, one end of each rotating shaft extends to the inside of a fixing box and is fixedly sleeved with a second worm wheel, a second worm is rotationally connected inside the fixing box, bearings are arranged outside two ends of the second worm, and one end of the second worm extends to the outer side of the fixing box.
