Welding type probe, intelligent bolt and assembly process thereof

Abstract

The invention provides a welding type probe, an intelligent bolt and an assembly process thereof, and belongs to the technical field of ultrasonic stress. The problems that an existing intelligent bolt is large in machining difficulty, and large-batch production is not facilitated are solved. The probe comprises a standard bolt and a probe package. The probe package is welded and fixedly connectedwith the upper surface of the standard bolt. The probe package comprises a sheath, contacts and a wafer. The sheath is further provided with a mounting groove and a through hole. The mounting grooveis used for positioning and mounting the wafer, the upper surface of the wafer is fixedly connected with the sheath in an insulating manner. The through hole is used for mounting the contacts, gaps exist between the contacts and the sheath, damping layers are filled in the gaps, and the upper surface of the wafer is fixedly connected with the bottom surfaces of the contacts and conductively connected. The probe has the advantages of being convenient to use, simple in structure, low in machining and assembling difficulty, low in production cost and high in detection precision.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic stress, and in particular relates to a welded probe, an intelligent bolt and an assembly process thereof. Background technique [0002] With the further deepening of my country's modernization and international cooperation, a large number of infrastructure projects urgently need to be put into construction, such as water conservancy and hydropower facilities, houses, bridges, etc. In the construction process and operation phase of these engineering structures, in order to ensure the safety of engineering objects, protect the lives and property of personnel and the surrounding environment, it is necessary to carry out necessary stability and health monitoring. At present, as a large number of connecting parts, bolts mainly exist in the field of equipment manufacturing with traditional structure and design, relying on manual methods to adjust their tightness, tens of thousands of bolts are used o...

Problems solved by technology

At present, smart bolts are used as nodes for monitoring. However, most of the existing smart bolts use embedded sensors. This way of embedding sensors inside will destroy the strength of the bolt itself. In actual use, the specifications and strength of the bolts are clearly regulated. Requirements, it is necessary to implant components inside the cavity of the bolt and meet the requirements of relevant specifications, which is very difficult to process and is not conducive to mass production
