Ultrasonic rapid thickness measuring device capable of automatically supplying coupling agent

Abstract

The invention discloses an ultrasonic rapid thickness measuring device capable of automatically supplying a coupling agent. The ultrasonic rapid thickness measuring device comprises a thickness gaugebody, an ultrasonic sensing device, a coupling agent storage mechanism and a coupling agent extrusion mechanism. A coupling agent is stored in the coupling agent storage mechanism. The coupling agentextrusion mechanism comprises a piston rod, an extrusion pre-tightening spring, a piston, a piston cover, a liquid storage cylinder body, a limiting ring, a piston rod handle, a coupling agent liquidoutlet and a coupling agent liquid inlet. Besides, the ultrasonic sensing device further comprises an adapter knife handle, an external limiting sleeve, an internal sliding sleeve, an annular sleeve,a sliding pin and a sensor pre-tightening spring. According to the ultrasonic rapid thickness measuring device, after the ultrasonic sensing device makes contact with a to-be-measured workpiece, the periphery of the contact face of the ultrasonic sensor and the to-be-measured is automatically filled with the coupling liquid, so that coupling agent does not need to be smeared manually and thus manpower is greatly saved; and the working efficiency of the ultrasonic rapid thickness measuring device is improved.

Description

Technical field [0001] The invention belongs to the field of electronic testing equipment, and specifically relates to an ultrasonic rapid thickness measurement device capable of automatically supplying couplant, and can be used for rapid thickness measurement of target parts in a multi-axis linkage numerical control machine tool or a multi-degree-of-freedom joint arm. Background technique [0002] Ultrasonic thickness gauge is based on the principle of ultrasonic pulse reflection for thickness measurement. When the ultrasonic wave emitted by the ultrasonic sensor reaches the interface of the material through the measured object, the pulse is reflected back to the ultrasonic sensor to accurately measure the propagation time of the ultrasonic wave in the material. To determine the thickness of the measured material. This principle can be applied to all kinds of materials that can make ultrasonic waves propagate inside them at a constant rate. [0003] When using the ultrasonic meth...
