Detailed description of the invention
Fig. 1 is the utility model structural profile illustration.
Specific embodiment
Below according to attached drawing and in conjunction with the embodiments, the utility model is described in further detail.
Integral type inner spline gear groove width and position precision cubing shown in the drawings, it is by spline plug gauge 1, retaining ring 2, spring 3
It is collectively constituted with positioning sleeve 4.The spline plug gauge 1 is a kind of more shoulder axis, it is equipped with and is sequentially connected the guiding shaft part 1.1 connect,
External splines shaft part 1.2, positioning shaft part 1.3 and handle shaft part 1.4.The guiding shaft part 1.1 of spline plug gauge 1 is located at external splines shaft part
1.2 outer ends, outside diameter d ' determining by the internal splined hole size of workpiece 5, d' fit tolerance is than 5 calibration value of workpiece in the present embodiment
A high grade, i.e. 5 calibration value of workpiece are Φ 28H7, d' is Φ 28H6.What is be connected with guiding shaft part 1.1 is external splines shaft part
1.2, because external splines shaft part 1.2 and 5 internal spline of workpiece cooperate, in order to ensure detection accuracy, it is desirable that the two fit tolerance is than workpiece 5
Calibration value is high, and the present embodiment is higher by a grade.The positioning sleeve 4 is made of the counterbore and through-hole of built-in coaxial, it is for surveying
The spline pitch circle bus of amount workpiece 5 connect benchmark experiment with driving member.The counterbore internal diameter D' of positioning sleeve 4 is equal to work in structure
The locating shoulder outer diameter D of part 5, i.e. nominal dimension are equal.In order to ensure detection accuracy, it is desirable that the two fit tolerance is marked than workpiece 5
The high grade of definite value, workpiece 5 allows with the location error for connecting benchmark to be Φ 50H in the present embodiment7, and positioning sleeve 4 is heavy
Hole internal diameter D' allows location error to be Φ 50H6.Before detection, positioning sleeve 4 is sleeved on the locating shaft of spline plug gauge 1 with axially extending bore
In section 1.3, in order to reduce position error, the two cooperation uses transition fit, and with the retaining ring for being equipped with radial direction lock-screw 2.1
