Endoscope detection apparatus used for detecting internal surface of stress cone

Abstract

The invention provides an endoscopic detection device for detecting the inner surfaces of stress cones. The device comprises a first linear motion part, a rotary motion part and a second linear motion part, wherein the first linear motion part provides linear motion in a first direction; the rotary motion part is arranged on the first linear motion part and provides rotary motion; a fixture for installing a stress cone is arranged on the rotary motion part; the second linear motion part provides the linear motion in a second direction; the second direction is perpendicular to the first direction; and an endoscopic probe facing the fixture is arranged on the second linear motion part. The device ensures that the endoscopic probe can accurately and adjustably stretch into the inside of the stress cone so as to acquire the image of the inner surface of the stress cone, and the acquired image is stable and clear as the interval between the endoscopic probe and the inner wall of the stresscone is fixed.

Description

technical field [0001] The invention relates to an endoscopic detection device for detecting the inner surface of a stress cone. Background technique [0002] The stress cone is the core component of the high-voltage cable accessories (terminal or intermediate joint). It directly affects the product quality of the accessory and whether the cable line can run safely and stably for a long time. Usually, during the installation process of power cable accessories, the manufacturing quality of the accessories must be checked out of the box, especially the quality of the stress cone is the focus of the unpacking inspection. [0003] At present, the commonly used method of inspecting the stress cone is visually inspecting with the help of sunlight or the light of a flashlight, but it is not easy to find defects, especially small defects. If the defect of the stress cone cannot be found in time, it may cause the breakdown of the stress cone after the cable accessories are installe...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used method of inspecting the stress cone is to use the light of the sun or a flashlight to visually inspect it with the naked eye, but it is not easy to find defects during this inspection, especially small defects are difficult to find

If the defect of the stress cone cannot be found in time, it may cause the breakdown of the stress cone after the cable accessories are installed, and the consequences will be very serious

Even if a defect is found, it is impossible to accurately measure the size of the defect through visual inspection with the naked eye. Furthermore, the defect can only be recorded by drawing pictures and text descriptions, and an accurate file cannot be left. Therefore, this inspection method is difficult for judging the stress cone. It is very difficult to use
