Problems solved by technology

However, the wheel plates on both sides of the device are relatively movable, and only the dry coupling material affects the synchronization of the two. For this reason, the rotation angles of the wheel plates on both sides will be out of sync, resulting in torsional deformation of the dry coupling layer, causing the dry coupling layer to fall off, or causing The dry coupling layer has uneven wall thickness, which affects the thickness measurement accuracy

Abstract

The invention relates to a wheel-type dry coupling ultrasonic thickness measuring probe. Wheel plates at two sides of the wheel-type dry coupling ultrasonic thickness measuring probe are kept to be synchronous via a gear synchronization device; the gear synchronization device comprises a synchronization rod and two first gears arranged at two ends of the synchronization rod respectively; two sides of the two wheel plates are provided with two second gears respectively; the two first gears on the synchronization rod are engaged with the two second gears at two sides of the wheel plates respectively; and the wheel plates at two sides are driven to rotate synchronously when the synchronization rod rotates. As the synchronization rod and the first gears are adopted, the wheel plates at two sides do not rotate relatively, and thus, a dry coupling material adhesive or tightly attached to the wheel plates is ensured not to be deformed, be crumpled and not to fall; and the synchronization rod is actively driven by a motor, through a controller and a velometer, relative rest of contact points is ensured when the wheel plates move on a measured surface, sliding is not generated, the dynamic thickness measuring precision is thus ensured, wear is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of ultrasonic thickness-measuring probes, in particular to a wheel-type dry-coupled ultrasonic thickness-measuring probe for metal thickness measurement. Background technique [0002] The currently used wheel-type dry-coupled ultrasonic thickness measuring probe is composed of an ultrasonic water immersion focusing probe, a probe frame, a wheel plate shaft, a wheel plate and a dry coupling material. Usually the probe frame is installed in the middle of the wheel shaft, the ultrasonic water immersion focusing probe is installed on the probe frame, the wheel plate is installed on both sides of the wheel shaft, the dry coupling material is bonded or fixed on the wheel plate, and the wheel plate rotates around the wheel shaft during movement. However, the wheel plates on both sides of the device are relatively movable, and only the dry coupling material affects the synchronization of the two. For this reason, th...
