An Ultrasonic Thickness Gauge Easy to Fix and Adjust

Abstract

The invention relates to a convenient-fixing and adjustment ultrasonic thickness measuring instrument which comprises a host computer, a connecting line, a holding rod, a push plate, a detecting mechanism and two fixing mechanisms. The host computer is provided with a display screen and a plurality of buttons. The fixing mechanism comprises a connecting board, a receiving assembly, a side plate, afixing assembly and a movable plate. The fixing assembly comprises a first motor and two fixing units. The fixing unit comprises a bearing, a first driving shaft, a movable block and a supporting rod. The detecting mechanism comprises a driving rod, a swinging rod, a probe, a detecting assembly, a collar, a fixing rod and two driving assemblies. The driving assembly comprises a connecting rod, asecond motor and a turntable. According to the convenient fixing and adjustment ultrasonic thickness measuring instrument, a to-be-detected pipe is clamped by two movable boards through the fixing mechanism, thereby preventing probe shake in a detecting process. Furthermore, the probe angle is adjusted through the detecting mechanism so that the probe is aligned with the axis of the pipe for measurement, thereby improving detecting precision of the equipment.

Description

technical field [0001] The invention relates to the field of detection instruments, in particular to an ultrasonic thickness gauge that is easy to fix and adjust. Background technique [0002] The ultrasonic thickness gauge measures the thickness according to the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the interface of the material, the pulse is sent back to the probe. By accurately measuring the propagation time of the ultrasonic wave in the material, the Determine the thickness of the material being measured. Ultrasonic thickness gauges can measure the thickness of various pipes and pressure vessels in production equipment, detect their degree of thinning after being corroded during use, and can also accurately measure various plates and various processed parts. [0003] However, when the existing ultrasonic waves measure some small pipes, due to the small measured area o...

Problems solved by technology

[0003] However, when the existing ultrasonic waves measure some small pipes, due to the small measured area of ​​the pipe, the probe cannot be accurately aligned with the pipe, resulting in deviations in the measured value. Not only that, but limited by the testing level of the testers, when detecting During the process, the probe is prone to vibration, resulting in fluctuations and deviations in the detection value, which further reduces the practicability of the existing ultrasonic thickness gauge
