An ultrasonic thickness gauge with a stable contact between the probe and the workpiece

Abstract

The invention relates to the technical field of ultrasonic vehicle thickness gauges, and discloses an ultrasonic thickness gauge with stable contact between the probe and the workpiece, including a thickness gauge main body, a movable connection sleeve is clamped on the top of the thickness gauge main body, and the movable joint The upper end of the connection sleeve is fixedly connected with a detection wire, and the end of the detection wire far away from the movable connection sleeve is connected with an anti-folding head, and the lower end of the anti-folding head is fixedly connected with a probe shell, and the outer surface of the probe shell is fixedly connected with a card piece. The probe is in stable contact with the workpiece ultrasonic thickness gauge, by adding a probe shell outside the probe head, and connecting the probe shell inside the probe protective cover, and setting a fixed ring inside the probe protective cover, and at the same time on the fixed ring The suction cup is threaded and controlled by the arm lever. When probing, the suction cup is adsorbed on the surface of the object, and the probe head is attached to the object by pushing the probe protective cover, so that the probe head does not need to be held.

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] 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. Measure the thickness of the material. [0003] When the existing ultrasonic thickness gauge is in use, it needs a hand-held fixed probe head and a hand-held host to hold the host, which is very inconvenient to use. Therefore, a thickness gauge with a probe head with a stable fixing device is now provided. Solve the above problems.
