在装配发动机的时候,置入气门销之后要检验这些气门销是否存在或其装配是否正确。到目前为止所采用的自动装配气门销机械,其检验都要求装配流水线处于静止状态。这就必然导致装配时间的延长。 为了使检验过程自动化,研制了一个可接触的按光截面法工作的检验系统。其方法是一条狭窄的光带投射到被检验的气门销和气门盘上,并通过电视摄象机得到一个反射图象(图 When assembling the engine, verify that these valve pins are present or that they are properly assembled after inserting the valve pins. So far the automatic assembly of valve pin machinery used, the test requires the assembly line in a quiescent state. This will inevitably lead to the extension of assembly time. In order to automate the inspection process, a contact inspection system that works according to the light section method was developed. The method is to project a narrow band of light onto the valve pin and valve disc to be inspected and obtain a reflected image from the television camera
