A Comprehensive Detection System of Automobile Valve Push Rod

Abstract

The invention discloses a comprehensive detection system for an automobile valve push rod. The comprehensive detection system comprises a workbench, a push mechanism, a detection device, a conveying mechanism and a sorting device. The detection device comprises a valve push rod rod-portion surface eddy current flaw detection mechanism, a circle run-out measurement mechanism, a length measurement mechanism and a ball head hardness measurement mechanism. All the mechanisms are arranged on a conveying line of the conveying mechanism with the sequence not limited. The comprehensive detection system for the automobile valve push rod integrates all detection functions and capable of conducting rod-portion crack detection of the push rod, rod-portion circle run-out detection, push rod length detection and ball head hardness detection; the comprehensive detection system is intensive in size and efficient and convenient to operate; and compared with traditional single object detection equipment, performance information of the valve push rod can be obtained faster and more effectively. By means of the system, fully-automatic, nondestructive and 100% full detection of the automobile valve push rod is achieved, and multi-parameter comprehensive detection is achieved.

Description

Technical field [0001] The invention relates to a non-destructive detection device for an automobile valve push rod, in particular to a comprehensive detection system for an automobile valve push rod. Background technique [0002] The valve push rod is one of the important parts of the automobile engine, and the safety and reliability of its operation will directly affect the modern automobile industry. Because of its harsh operating environment, it is subject to the periodic action of the reciprocating force of the valve lifter and the pressure alternating force during operation. The two ball heads of the putter rub against the valve lifter and the valve respectively. Therefore, the ball heads at both ends of the putter are required to have high hardness and high wear resistance, and the putter must have sufficient comprehensive mechanical properties. Usually the material of the putter is 45# steel, the hardness of the rod is adjusted to 26~31HRC, and the ball heads at both end...
