Full automatic assembling technology of air valve of rocker arm of engine and production line

Abstract

The invention provides a full automatic assembling technology of an air valve of a rocker arm of an engine and a production line. The assembling technology comprises the steps of feeding the rocker arm; mounting an adjusting screw and a releasing nut; mounting a roller and a rolling pin; riveting a rocker arm rolling pin; detecting the riveted rocker arm rolling pin; mounting a rocker arm shaft tothe rocker arm; and correspondingly mounting a check ring and a clamping spring at two ends. The production line comprises a rocker arm feeding system, a rocker arm assembly split charging system anda rocker arm combined charging system which are sequentially arranged; a rocker arm feeding robot is arranged between the rocker arm feeding system and the rocker arm assembly split charging system;and an accessory feeding robot is arranged between the rocker arm assembly split charging system and the rocker arm combined charging system. With the adoption of the assembling technology, the roller, the rolling pin and the rocker arm are assembled in one time; the rocker arm shafts are synchronously mounted to an air inlet rocker arm and an air outlet rocker arm, and the clamping spring and thecheck ring are automatically mounted at two ends. Therefore, the assembling efficiency is high, and the accuracy is high; the mounting space is reduced; the conveying efficiency, the assembling efficiency and the assembling accuracy are improved; the full automatic assembling is realized; in addition, the process quality control can be performed; the arrangement is reasonable; and the material conveying is smooth.

Description

technical field [0001] The invention relates to a process for assembling an engine valve rocker arm and a production line for realizing the process route, belonging to the technical field of engine valve rocker arm assembly. Background technique [0002] car engine valve rocker arm figure 1 As shown, it includes the intake rocker arm 03, the rocker arm shaft 04 and the exhaust rocker arm 06.
