Ultrasonic thickness measurement device

Abstract

The invention discloses an ultrasonic thickness measurement device. The device comprises a thickness measurement device main body, a measurement probe, an ultrasonic emitter, an ultrasonic receiver and a fixed suction disc. A display screen and an operation button are installed on the thickness measurement device main body. The display screen is arranged on the top of the operation button. A wire connection port is installed in the top of the thickness measurement device main body. A connection line is installed on the wire connection port. The measurement probe is installed on one end of the connection line. According to the invention, through a press rod and the fixed suction disc installed on one side of the measurement probe, it is convenient to fix the measurement probe on a to-be-measured object through the fixed suction disc and the press rod during thickness measurement, and effects on precision of the thickness measurement imposed by displacement of the probe caused by manual factors are avoided during measurement processes of a handheld measurement probe, so measurement precision of the thickness measurement device is improved, hands of a measurement worker are released, it is convenient for the worker to record data, difficulty in using of the thickness measurement device is reduced, heat dissipation performance of the thickness measurement device main body is improved and effect degrees to the thickness measurement precision of the thickness measurement device imposed by temperature rise are reduced.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to an 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 reflected back to the probe. The thickness of the material can be measured, and all kinds of materials that can make the ultrasonic wave propagate inside it at a constant speed can be measured by this principle. However, when the existing thickness gauge is in use, the measurement probe of the thickness gauge needs to be held and fixed on the surface of the measured object during the measurement process. On the one hand, it will confine the hands of the measurement personnel, making it difficult to use the thickness gauge and not convenient for the measure...

Problems solved by technology

However, when the existing thickness gauge is in use, the measurement probe of the thickness gauge needs to be held and fixed on the surface of the measured object during the measurement process. On the one hand, it will confine the hands of the measurement personnel, making it difficult to use the thickness gauge and not convenient for the measurement personnel. Recording of measurement data; on the one hand, the probability of displacement of the measuring probe increases due to human factors during the hand-holding process, which affects the measurement accuracy of the thickness gauge; and due to the poor heat dissipation of the thickness gauge itself, when the temperature of the thickness gauge rises, will affect the accuracy of thickness measurement
