Hole is fixedly connected.
Further, at least two connecting holes are offered on first spline plug gauge, the section of the connecting hole is in T words
Shape is equipped with fixing bolt in the connecting hole, and the upper surface of the fixing bolt is not higher than the upper surface of connecting hole, the fixation
The lower part of bolt is fixedly connected with second spline plug gauge.
The use step of this detection device is：The second spline plug gauge of detection device is entered into the tooth socket of internal spline I first,
And be allowed to pass through from internal spline I, the second spline plug gauge is made to enter in gear medial launder, then suitable or counterclockwise rotation detection
Device so that the second spline plug gauge enters II mouthful of end of internal spline and imports the tooth socket of internal spline II, while causes the first spline plug
Rule enter internal spline I, axially downwardly push detection device later.If passed through, product processing is qualified, if can't pass,
It is unqualified.
The remarkable result of the utility model is：It is simple in structure, it is easy to operate, by the efficient combinations of two internal spline feeler gauges into
It is detected while two internal splines of row, substantially increases detection efficiency, enterprise is contributed to control testing cost.
Description of the drawings
