Detailed description of the invention
By particular specific embodiment, embodiments of the present invention being described below, those skilled in the art can be taken off by this specification The content of dew understands other advantages and effect of the present invention easily.
Refer to Fig. 1 to Fig. 2.It should be clear that structure depicted in this specification institute accompanying drawings, ratio, size etc., the most only in order to Coordinating the content disclosed in specification, understand for those skilled in the art and read, being not limited to the present invention can implement Qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, Under not affecting effect that the present invention can be generated by and the purpose that can reach, all should still fall at disclosed technology contents Obtain in the range of containing.Meanwhile, in this specification cited as " on ", D score, "left", "right", " middle " and " one " etc. Term, be merely convenient to understanding of narration, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or Adjust, changing under technology contents without essence, when being also considered as the enforceable category of the present invention.
As it is shown in figure 1, the present invention provides a kind of monodentate number external splines distance over bar measurement apparatus, it includes having inclined support surface 11 Support platform 1, and the location shell 4 being located in inclined support surface 11, be placed in location shell 4 for fixing flower outside monodentate number The spline housing 8 of key, and the first gauge head 3 and the second gauge head 5 being located on spline housing 8, the first gauge head 3 and the second gauge head 5 Being positioned at same straight line and be oppositely arranged, the first gauge head 3 maintains static, the movable setting of the second gauge head 5 and the survey with amesdial 7 Examination end contacts;Spline housing 8 is eccentric part, during measurement, make tested spline and the first gauge head 3 on monodentate number external splines, Two gauge heads 5 are on the same line.The present invention uses and is positioned in inclined support surface 11 by monodentate number external splines to be measured, utilizes it Deadweight can well contact with two gauge heads, and by spline housing 8 is set to eccentric part, it is ensured that monodentate number external splines Upper tested spline and first gauge head the 3, second gauge head 5 are on same straight line, it is achieved the first gauge head and the second gauge head can quick, Stretch in two relative splines of monodentate number external splines accurately, it is achieved accurately measure the distance over bar of monodentate number external splines.
For ease of preferably making the second gauge head insert in the spline of monodentate number external splines, above-mentioned second gauge head 5 is equipped with regulation Spring 6, when tested monodentate number external splines 9 is placed in spline housing, as in figure 2 it is shown, the second gauge head 5 can be retracted backward, single After number of teeth external splines 9 is inserted, regulation spring 6 makes the second gauge head 5 stretch out in insertion spline.First gauge head 3 and the second gauge head In the 5 tested splines all stretching into monodentate number external splines 9, read data by amesdial 7.
