An Easy-to-operate Ultrasonic Thickness Gauge

Abstract

The invention relates to an ultrasonic thickness meter convenient to operate. The ultrasonic thickness meter comprises a main machine, a connecting line, a holding rod, a push plate and a thickness measuring device and is characterized in that the thickness measuring device comprises a thickness measuring mechanism and a plurality of fixing mechanisms, each fixing mechanism comprises a telescopingcomponent, a moving plate, a direction adjusting component, an air suction chamber, an air suction pipe and a sucker, the thickness measuring mechanism comprises a rotating component, a first motor,a rotary disc, a thickness measuring component and a scanning component, the thickness measuring component comprises a first air cylinder, a first piston, a moving unit and a probe, and the scanning component comprises a second air cylinder, a second piston and a scanning unit. The ultrasonic thickness meter the suckers are allowed to attach to the surface of a to-be-measured object through the fixing mechanisms so as to fix the push plate, and the two hands of a measuring worker can be freed to do other work; in addition, the thickness measuring mechanism adjusts the angle of the probe afterthe surface shape of the to-be-measured object is determined to allow the probe to vertically aim at the to-be-measured object so as to increase the measuring precision of the ultrasonic thickness meter.

Description

technical field [0001] The invention relates to the field of testing equipment, in particular to an easy-to-operate ultrasonic thickness gauge. 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] The existing ultrasonic thickness gauge is mainly composed of a host, a probe and a connecting wire. When in use, the ins...

Problems solved by technology

[0003] The existing ultrasonic thickness gauge is mainly composed of a host, a probe and a connecting wire. When in use, the inspector needs to hold the host with one hand and the probe with the other hand to move and inspect the workpiece surface. Since the inspector's hands are bound, the inspection It is difficult for personnel to carry out recording work, which makes it inconvenient to use the ultrasonic thickness gauge. Not only that, when measuring, it is necessary to align the probe with the surface of the workpiece for detection. There are deviations in the detection results. In the actual measurement, due to the limitation of the detection level of the detection personnel, the probe and the surface of the workpiece are prone to tilt, resulting in a decrease in the measurement accuracy of the equipment.
