Embodiment Construction

[0019] Such as Figure 2 to Figure 7 Shown, the detection method of a kind of engine cylinder head valve guide hole of the present invention and camshaft hole distance, comprises the following steps:

[0020] (1) Make measurement and inspection tools, which include positioning bases, measuring mandrels, through-end inspection tools and stop-end inspection tools. The positioning base of the measuring and checking tool is provided with a cylindrical positioning pin and a diamond-shaped positioning pin that can locate the ground of the cylinder head. The two ends of the positioning base of the measuring and checking tool are also connected with a pair of oppositely arranged supports. The two supports are respectively There are positioning holes for the support. The outer diameter of the measuring mandrel is equal to the hole diameter of the camshaft hole. The through-end gauge and the stop-end gauge respectively include a measuring card body, a positioning shaft, and a measuring...

Abstract

The invention provides an engine cylinder head valve guide hole and camshaft hole distance detection method, and relates to a detection method. The method comprises the steps that (1) a measuring gagewhich comprises a positioning base, a measuring mandrel, a go side gage and a not-go-end end gage is manufactured, and the outer diameter of the measuring mandrel is equal to the hole diameter of a camshaft hole; (2) a cylinder head is positioned on the positioning base, and the measuring mandrel is positioned in each camshaft hole; and (3) the go side gage and the not-go-end end gage are used todetect the distance between a valve guide hole and the edge of the measuring mandrel. The method provided by the invention can accurately detect whether the distance between an engine cylinder head valve guide and the camshaft hole meets requirements, and has the advantages of simple operation, quick and accurate operation, practicality and convenience.

Description

technical field [0001] The invention relates to a detection method, in particular to a detection method for the distance between an engine cylinder head valve guide hole and a camshaft hole. Background technique [0002] The engine cylinder head is an important part of the car. The distance between the valve guide hole of the engine cylinder head and the center of the camshaft hole is the key dimension of the cylinder head. Once it is out of tolerance, it will inevitably affect the assembly of the cylinder head and the performance of the engine. Such as figure 1 In the figure, it is a cylinder head of a miniature automobile engine. The distance between the valve guide hole of the cylinder head and the center of the camshaft hole in the figure is 39.5±0.05, which is the key dimension of the cylinder head. detection. If the three-coordinate detection is used, not only the efficiency is low, the number of sampling samples is limited, but also the inspection cost is high. Co...
