A production quality inspection system for electric locomotive connectors

Abstract

The invention provides a system for detecting the manufacturing quality of an electric locomotive connector. The system is composed of a shell, an oil pressure detection system and an electric detection system. The system is set based on the actual mechanical structure of the 56-pin connector with the highest point number of the electric locomotive as a reference and is able to match the electriclocomotive connector completely, so that whether a shortening problem occurs at the electric locomotive connector is detected accurately. According to the system, on the basis of the Pascal's law (being the principle of static pressure transmission), one set of precise oil pressure transmission system in good butt joint with the electric locomotive connector is made. With a hydraulic pressure sensor, a hydraulic analog signal is detected; and the analog signal is amplified by a transmitter and then a light-emitting diode is driven, so that whether the connector has a shortening quality problemis determined. The system has advantages of reasonable structure, high sensitivity, safety, and reliability, high flexibility in use, great convenient, and great simpleness; and a problem that no method is provided for detecting the manufacturing quality of an electric locomotive connector effectively and rapidly is solved.

Description

technical field [0001] The invention relates to a manufacturing quality inspection system for electric locomotive connectors, and is especially suitable for inspecting whether the manufactured electric locomotive connectors have shrinkage quality problems. Background technique [0002] In the field of international and domestic electric locomotive manufacturing, the shrinkage detection of connector production quality has become a difficult problem. The connector shrinkage detection tools commonly used in the world and domestically are all single-body, which can only detect the position of one ferrule point at a time. Shrinking condition. On electric locomotive products with complex control systems, the number of large-point connectors is relatively large, and an average car has dozens of large-point connectors. Because the number of connector points to be detected is huge, using the original The needle shrinkage detection tool can only realize individual sampling inspection...

[0002] In the field of international and domestic electric locomotive manufacturing, the shrinkage detection of connector production quality has become a difficult problem. The connector shrinkage detection tools commonly used in the world and domestically are all single-body, which can only detect the position of one ferrule point at a time. Needle reduction

On electric locomotive products with complex control systems, the number of large-point connectors is relatively large, and an average car has dozens of large-point connectors. Because the number of connector points to be detected is huge, using the original The needle shrinkage detection tool can only realize individual sampling inspections, and the quality of the connectors cannot be guaranteed. As a result, after the electric locomotive leaves the factory and has been running for a period of time in the locomotive depot, the connectors often cause control system failures due to shrinkage. The safety of locomotive operation is threatened, and the cost of after-sales maintenance is greatly increased
