Portable ultrasonic thickness gauge

Abstract

The invention relates to a portable ultrasonic thickness gauge which comprises a main body, a cable and a probe and further comprises a winding and unwinding mechanism and a preprocessing mechanism. The winding and unwinding mechanism comprises a first motor, a driving shaft, a guiding ring and a guiding assembly. The guiding assembly comprises a lead screw, a triggering rod, a guiding rod, a driving sleeve, a transmission sleeve, a connecting lantern ring, a fourth magnet, a support, a first gear, a third gear, a driving unit, a moving sleeve, two connecting sleeves and two third magnets. Thepreprocessing mechanism comprises a driving assembly, a reinforcing lantern ring, a cleaning brush, a power sleeve, a fifth gear and two connecting assemblies. According to the portable ultrasonic thickness gauge, the cable can be wound to the driving shaft through the winding and unwinding mechanism, and thus the storage convenient level of the ultrasonic thickness gauge is increased; and the cleaning brush can be driven to rotate through the preprocessing mechanism, then the surface of a detected object is cleared through the cleaning brush, and thus the probability of breakdown occurring to the probe is decreased.

Description

technical field [0001] The invention relates to the field of ultrasonic thickness measuring equipment, in particular to a portable ultrasonic thickness measuring instrument. Background technique [0002] Ultrasonic thickness measuring equipment is used for thickness measurement. When the ultrasonic pulse emitted by the probe passes through the measured object and reaches the interface of the material, the pulse is reflected back to the probe, and the thickness of the measured material is determined by accurately measuring the propagation time of the ultrasonic wave in the material. Thickness, all kinds of materials that can make ultrasonic waves propagate inside them at a constant speed can be measured by this principle. [0003] As a kind of ultrasonic thickness measuring equipment, ultrasonic thickness gauge is widely used in people's life. Generally, the main body of ultrasonic thickness measuring equipment is connected to the probe through a cable, but the cable and prob...

Problems solved by technology

[0003] As a kind of ultrasonic thickness measuring equipment, ultrasonic thickness gauge is widely used in people's life. Generally, the main body of ultrasonic thickness measuring equipment is connected to the probe through a cable, but the cable and probe of the ultrasonic thickness gauge cannot be retracted, resulting in It is difficult to carry the ultrasonic thickness gauge, which reduces the practicability of the ultrasonic thickness gauge. Not only that, when the ultrasonic thickness gauge detects the workpiece, if there is rust or debris on the surface of the workpiece, it will cause damage to the probe. thus causing unnecessary losses to people
