Abstract

The invention provides a locomotive cylinder cover cross arm guide rod installation precision detection system and method. The device comprises a positioning detection platform, an image acquisition system, a main control system and a driving device, the driving device is connected with the image acquisition system, the main control system is connected with the image acquisition system and the driving device, and the positioning detection platform is used for placing a cylinder cover cross arm guide rod to be detected. The driving device is used for driving the image acquisition assembly to move to a position right above a cross arm guide rod of the cylinder cover to be detected under the control of the main control system, the image acquisition system is used for acquiring an original image and transmitting the original image to the main control system, and the main control system is used for carrying out preprocessing and feature extraction on the image; and judging whether the deflection angle of the cross arm guide rod key groove exceeds a qualified range or not based on a preset standard. According to the detection system, automatic detection is realized based on the computer and the image acquisition assembly, the detection efficiency is improved, and the false detection rate is greatly reduced; and meanwhile, the labor cost is reduced through an automatic detection mode.

Description

technical field

[0001] The invention relates to the technical field of installing a cross-arm guide rod of a locomotive cylinder head, in particular to a system and method for detecting the installation accuracy of a cross-arm guide rod of a locomotive cylinder head. Background technique

[0002] In the initial stage of engine technology development, dual-valve technology (single-inlet and single-row) is generally used. At this stage, the opening and closing of the valves are generally directly controlled by rocker arms (connecting rods), and each rocker arm (connecting rod) Can control a valve. With the development of science and technology, the continuous improvement of engine technology, and the requirements of environmental protection, multi-valve technology (multi-inlet and multi-row) has been produced. The emergence of multi-valve technology requires the rocker arm to be able to control two (or more) valves with the same name at the same time in terms of structure. At...
