Conical plug gauge painting thickness inspection gauge block and inspection method

Abstract

The invention relates to an inspection technology of a comprehensive inspection device, in particular to a conical plug gauge painting thickness inspection gauge block and inspection method. The conical plug gauge painting thickness inspection gauge block comprises a cube; one surface of the cube is of a V-shaped surface structure, and a plurality of inspection grooves which are parallel to one another are formed in one side of the V-shaped surface; the inspection grooves are perpendicular to the middle line of the V-shaped surface, and the distances between the adjacent inspection grooves areequal; the inspection grooves penetrate through the plane; and the depths of the inspection grooves are sequentially increased or decreased. During measurement, the surface of a marked plug gauge iscoated with a red lead oily coating or Prussian blue oil with a specified thickness; and when the thickness of the coloring layer is detected, the two V-shaped surfaces of the inspection gauge block are in contact with the conical surface of the plug gauge and then slowly move along the circumferential direction of the plug gauge, and the thickness of the coloring layer is judged according to thecoloring condition in the plurality of inspection grooves.

Description

technical field [0001] The invention relates to the inspection technology of a comprehensive inspection tool, in particular to a measuring block for inspecting the coloring thickness of a tapered plug gauge and an inspection method. Background technique [0002] Cone gauges are divided into plug gauges and ring gauges. The ring gauge is painted on the inner cone surface and closely attached to the outer cone surface to be tested. After separation, the outer cone angle and angle of the outer cone are detected by observing the colored part, area size, and end surface depth on the outer cone surface to be tested. diameter gauge. When making ring gauges, to check whether the ring gauges are qualified is to apply red lead oil-based paint or Prussian blue oil with a specified thickness on the surface of the marked plug gauges, and then closely match the marked plug gauges with the tested ring gauges, and observe the ring gauges. The coloring of the surface is used to judge ( Fi...

AI Technical Summary

Problems solved by technology

[0006] (1) if Figure 8 Shown: The contact surface between the inspection block and the plug gauge is in a straight line, and it is easy to fall to one side, which affects the detection accuracy;

[0007] (2) if Figure 9 , 10 Shown: During detection, the inspection block is easy to incline with the plug cone, which affects the detection accuracy;

[0008] (3) During detection, in order to obtain the accurate thickness of the coloring (layer of Prussian blue oil), it is necessary to use inspection blocks with grooves of different depths for repeated detection, which is inefficient
