With handle shaft part.The positioning sleeve is made of the counterbore and through-hole of built-in coaxial.It is theed improvement is that：The positioning sleeve is with axis
It is sleeved on the positioning shaft part of spline plug gauge to through-hole, and makees axial limiting with the baffle ring equipped with radial lock-screw.It is described
Spring is placed in composition axial elasticity stretching structure between positioning sleeve and spline plug gauge.
As the scheme that is further improved, the guiding shaft part outside diameter d of the spline plug gauge ' by the internal splined hole of workpiece to true
It is fixed, a d' fit tolerances grade at least higher than part calibration value.
As the scheme that is further improved, outer spline section and the workpiece internal spline of the spline plug gauge coordinate, and the two cooperation is public
A difference grade at least higher than part calibration value.
As the scheme that is further improved, the counterbore internal diameter D' of the positioning sleeve is equal to workpiece locating shoulder outer diameter D, and the two is matched
Tolerance is closed than part calibration value to a few high grade.
As the scheme that is further improved, the axially extending bore internal diameter d of the positioning sleeve is equal to outside the positioning shaft part of spline plug gauge
Diameter, the two coordinate with transition is combined into.
As the scheme that is further improved, the spring is compression type springs.
Compared with prior art, the present invention having the positive effect that：
1, the coaxial fitting of spline plug gauge and positioning sleeve is formed integral type detection structure is simple, is easy to make, easy to operate；
2, on the basis of detection and localization inner spline gear groove width, sequentially make the position that spline pitch circle busbar connect basis with driving member
Error measure, due to being measured under same base condition, testing result is accurate；
3, the size of internal spline and Form and position error detect together, and detection efficiency at least doubles.
Description of the drawings
Fig. 1 is structure of the invention diagrammatic cross-section.
Specific implementation mode
Below according to attached drawing and in conjunction with the embodiments, the invention will be further described.
Integral type inner spline gear groove width and positional precision cubing shown in the drawings, it is by spline plug gauge 1, baffle 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 ' by the internal splined hole size of workpiece 5 determine that d' fit tolerances are 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 coordinate, in order to ensure accuracy of detection, 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 busbar 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 accuracy of detection, it is desirable that the two fit tolerance is marked than workpiece 5
The high grade of definite value, workpiece 5 allows and connect the site error of benchmark to be Φ 50H in the present embodiment7, and positioning sleeve 4 is heavy
Hole internal diameter D' allows site 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 is coordinated using transition, and with the baffle ring for being equipped with radial direction lock-screw 2.1
2 are used for axial limiting.The spring 3 is a kind of compression type springs, it is mounted between positioning sleeve 4 and spline plug gauge 1, thus group
At axial elasticity stretching structure.
Present invention actual use situation is as shown in the picture, the handle shaft part 1.4 of one holding spline plug gauge 1 of operative employee, separately
One is held workpiece 5 with locating shoulder one end towards the guiding shaft part 1.1 of spline plug gauge 1, guides the internal splined hole and flower of workpiece 5
The guiding shaft part 1.1 of key feeler gauge 1 coordinates.With being further inserted into for workpiece 5, realize the inner spline gear groove width of workpiece 5 by spline
The external splines shaft part 1.2 of feeler gauge 1 detects.If space width detection is qualified, workpiece 5 is continued into, until the locating shoulder of workpiece 5
Coordinate with the counterbore of positioning sleeve 4, using the site error value of the opposite tooth socket of counterbore detection locating shoulder of positioning sleeve 4, if positioning
The counterbore of set 4 accommodates the locating shoulder of workpiece 5, then is described site error in tolerance band, on the contrary then be judged to defective work.
Workpiece 5 returns to initial position under the action of spring 3 after detection, is loaded and unloaded convenient for workpiece 5.The present invention detects workpiece 5 together
The space width size and connection benchmark experiment of internal spline, due to being detected under the conditions of same positioning datum, detection knot
Fruit is accurate, also improves one times of detection efficiency or more, is particularly suitable for on-line checking.
