The inner circle surface of the tension sleeve is an inner conical surface, and a plurality of notches are processed in a circumferential direction of the tension sleeve. The outer circle surface at the front end of the mandrel is equipped with an outer conical surface, the tension sleeve sleeves on the mandrel, and the inner conical surface of the tension sleeve matches the outer conical surface at the front end of the mandrel. The mandrel is equipped with two radial cylindrical pins, the taper reduction sleeve sleeves on the mandrel and is equipped with two kidney slots corresponding to the positions of the cylindrical pins, and the kidney slots match the cylindrical pins. The tail end of the mandrel is equipped with a thread screw, the nut is in threaded connection with the tail end of the mandrel, and the taper reduction sleeve is located between the tension sleeve and the nut. The internal spline detecting tool of the utility model is simple in structure and good in reliability, is simple, convenient and rapid to operate, and can reflect the contact state of the inner spline more really.
Description
Technical field
The utility model relates to a kind of cubing of checking axle head female spline and axle cylindrical to beat, and specifically a kind of Detector for Internal Spline, belongs to mechanical part processing technique field.
Background technology
The concentricity of axle head female spline and axle cylindrical is the important guarantee of element precision, and the existing method of inspection is mainly the distance of utilizing between length bar detection limit rod and cylindrical, when measurement, every gear is all measured corresponding distance, then get ultimate range and amount small distance, both differences are beating between female spline and cylindrical.The method, must all measure by per tooth, to guarantee the accuracy of measurement result.But it is large that the method per tooth is measured required workload, and contact situation can not truly reflect the use state of female spline time.Therefore, when the method operation, not only require great effort but also time-consuming, efficiency is low, and cannot accurately reflect the true contact condition of female spline.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Detector for Internal Spline is provided, and it is simple in structure, and easy and simple to handle, quick, good reliability can reflect the contact condition of female spline more truly.
The technical scheme providing according to the utility model: Detector for Internal Spline, it is characterized in that: comprise expansion sleeve, mandrel, straight pin, spacer shell and nut, expansion sleeve outer round surface is provided with male splines, the path of the large footpath of described male splines and path and workpiece female spline to be detected and gapped with large footpath, the internal circular surfaces of described expansion sleeve is made as inner conical surface, and expansion sleeve is processed with many places breach in a circumferential direction; The outer round surface of described mandrel front end is made as male cone (strobilus masculinus), and described expansion sleeve is enclosed within on mandrel, and the inner conical surface of expansion sleeve matches with the male cone (strobilus masculinus) of mandrel front end; Two straight pins are radially installed on described mandrel, and spacer shell is sleeved on mandrel, and spacer shell is provided with two kidney slots corresponding with straight pin position, and described kidney slot matches with straight pin; Described mandrel tail end is provided with screw thread, and nut thread is connected on mandrel tail end, and described spacer shell is between expansion sleeve and nut.
As further improvement of the utility model, the end face center of described mandrel tail end is provided with center pit.
As further improvement of the utility model, two straight pins installing on described mandrel are symmetrical by 180 ° on the circumferencial direction of mandrel.
As further improvement of the utility model, described expansion sleeve is processed with six place's breach in a circumferential direction.
compared with prior art, advantage is the utility model:
(1) the utility model utilizes expansion sleeve structure, can realize the gapless of workpiece female spline and accurately feel relieved, and has improved the accuracy of detection of female spline, and expansion sleeve can realize quick tensioner with unclamp, easy and simple to handle.
(2) the utility model arranges center pit by the end face center at mandrel tail end, utilize the center hole of this center pit and workpiece self to coordinate, realize two top inspections, quicklook, simultaneously consistent with the benchmark used in machining process, ensure the accuracy of checking.

Brief description of the drawings
Fig. 1 is structure and the applicable cases schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the Detector for Internal Spline in embodiment is mainly made up of expansion sleeve 1, mandrel 2, straight pin 3, spacer shell 4 and nut 5.
As shown in Figure 1, expansion sleeve 1 outer round surface is provided with male splines, the path of the large footpath of described male splines and path and workpiece to be detected 6 female splines and gapped with large footpath, the internal circular surfaces of described expansion sleeve 1 is made as inner conical surface, and expansion sleeve 1 is processed with six place's breach in a circumferential direction; The outer round surface of described mandrel 2 front ends is made as male cone (strobilus masculinus), and described expansion sleeve 1 is enclosed within on mandrel 2, and the inner conical surface of expansion sleeve 1 matches with the male cone (strobilus masculinus) of mandrel 2 front ends; Two straight pins 3 are radially installed on described mandrel 2, and spacer shell 4 is sleeved on mandrel 2, and spacer shell 4 is provided with two kidney slot 4as corresponding with straight pin 3 positions, and described kidney slot 4a matches with straight pin 3; Described mandrel 2 tail ends are provided with screw thread, and nut 5 is threaded on mandrel 2 tail ends, and described spacer shell 4 is between expansion sleeve 1 and nut 5.
As shown in Figure 1, the end face center of described mandrel 2 tail ends is provided with center pit 2a.Two straight pins 3 installing on described mandrel 2 are symmetrical by 180 ° on the circumferencial direction of mandrel 2.
Principle of work of the present utility model is as follows:
When work, expansion sleeve 1 is packed in the female spline of workpiece 6, screw nut 5, nut 5 inwardly promotes spacer shell 4, and spacer shell 4 compresses expansion sleeve 1, the interaction of the male cone (strobilus masculinus) of the inner conical surface of expansion sleeve 1 and mandrel 2 front ends, the female spline of tensioner workpiece 6 gradually.Now utilize the center hole 6a of workpiece 6 and the center pit 2a of mandrel 2, can conveniently realize two top detection cylindricals and beat, detect thereby reach the object that female spline and cylindrical are beated.
