The invention relates to a cam shaft testing device, which comprises a tooling base (1), brackets (2, 3), a positioning block (4) and a limit toothed plate (7), wherein the brackets (2, 3), the positioning block (4) and the limit toothed plate (7) are fixed on the tooling base (1); the brackets (2, 3) are used for supporting a cam shaft sample (8); the toothed plate (7) is used for limiting the rotation of the cam shaft sample (8); and the positioning block (4) is used for positioning a buffer section on one side of the cam shaft sample (8) in a horizontal state.
Description
technical field The invention relates to the technical field of camshaft testing in the automobile industry, in particular to a camshaft hardness and bending resistance test fixture in the automobile industry. Background technique In GB / T230.1-2004 "Metal Rockwell Hardness Test Part One: Test Method", it is clearly stipulated that the sample should be placed on the rigid support smoothly, and the axis of the indenter should be perpendicular to the surface of the sample to avoid the occurrence of the sample. displacement. And in the prior art, during camshaft hardness test, be that camshaft peach is cut off from camshaft, process through grinding machine again, make two sides parallel and just can carry out hardness test. At present, there is no tooling or fixture that can fix the overall camshaft and adjust the position of the camshaft arbitrarily, so as to perform hardness or related tests. That is to say, the prior art cannot provide a tool that can support and position ...
