Ultrasonic thickness gauge with probe in stable contact with workpiece

Abstract

The invention relates to the technical field of ultrasonic vehicle thickness gauges and discloses an ultrasonic thickness gauge with a probe in stable contact with a workpiece. The thickness gauge comprises a thickness gauge body, a movable connecting sleeve is clamped to the top of the thickness gauge body, a detection wire is fixedly connected to the upper end of the movable connecting sleeve, an anti-folding head is connected to the end, away from the movable connecting sleeve, of the detection wire, a detection head shell is fixedly connected to the lower end of the anti-folding head, anda clamping block is fixedly connected to the outer surface of the detection head shell. The probe is an ultrasonic thickness gauge which is in stable contact with a workpiece. A detection head shell is additionally arranged outside a detection head; the detection head shell is connected to the interior of the probe protective sleeve; meanwhile, the fixing ring is arranged in the probe protection sleeve, the sucker is in threaded connection with the fixing ring and is controlled by the force arm rod, the sucker is adsorbed to the surface of an object during detection, the probe is attached to the object by pushing the probe protection sleeve, and the effect that the probe does not need to be held by hand is achieved.

Description

Technical field [0001] The invention relates to the technical field of ultrasonic thickness gauges, in particular to an ultrasonic thickness gauge with stable contact between a probe and a workpiece. Background technique [0002] Ultrasonic thickness gauge is based on the principle of ultrasonic pulse reflection for thickness measurement. When the ultrasonic pulse emitted by the probe reaches the interface of the material through the measured object, the pulse is reflected back to the probe by accurately measuring the time the ultrasonic wave travels in the material. Measure the thickness of the material. [0003] When the existing ultrasonic thickness gauge is in use, it needs a hand-held fixed probe and the other to hold the host. It is very inconvenient to use. Therefore, a thickness gauge with a stable fixing device for the probe is now provided. Solve the above problems. Summary of the invention [0004] (1) Technical problems solved [0005] In view of the shortcomings of the...
