Auxiliary tooling for inlaying hardness plugs and inlaying methods for hardness plugs

Abstract

The present invention discloses a hardness plug inlay auxiliary tool and a hardness plug inlay method. The hardness plug inlay auxiliary tool includes a tool body in round plate shape and a plurality of guide holes. The diameter of the tool body adapts to an inverted cone diameter of an inlaying machine; the thickness of the tool body is less than the height of the hardness plug; and the plurality of guide holes are used to place various hardness plug sample pieces; the guide holes vertically penetrate through the upper surface and lower surface of the tool body; and adjacent guide holes have equal spacing. The hardness plug inlay auxiliary tool uses guide holes in equal spacing for placing the samples, realizes array arrangement of hardness plugs in a fixed spacing, effectively guarantees ordered arrangement of hardness plugs in consistent spacing, simultaneously solves the problem that hardness plugs are easy to turn over by touch in the laying process, reduces the difficulty of sample preparation and improves the efficiency of sample preparation.

Description

technical field [0001] The invention relates to the field of temperature field tests of engine cylinder heads and pistons, in particular to an auxiliary tooling for inlaying hardness plugs and a method for inlaying hardness plugs. Background technique [0002] With the in-depth research on the reliability of engine combustion space, it is found that temperature is one of the important factors affecting the reliability of cylinder head and piston strength. The hardness plug that has been tested in the temperature field along with the engine cylinder head and piston is inlaid to make a sample, and the highest temperature experienced at the point where the hardness plug is located can be restored by testing its microhardness. [0003] At present, the inlaying methods of hardness plugs include: the first is to manually place the hardness plugs one by one on the lower mold of the inlay machine one by one without the aid of other auxiliary tools, and then lower the lower mold to t...

AI Technical Summary

Problems solved by technology

[0004] Since the number of hardness plugs sent for inspection is more than 200 pieces each time, and when the hardness plugs are inlaid by the two methods, the placement of each hardness plug is completely controlled by hand, and the orderly arrangement and the consistency of the spacing cannot be guaranteed.

In the process of arranging the hardness plug and lowering the lower mold of the mounting machine for these two inlaying methods, due to the small size of the hardness plug, the hardness plug is also easy to be knocked and tilted due to vibration, touch or strong air flow, resulting in the Chaotic, therefore, sample preparation is difficult and inefficient
