The invention discloses an inner spline rod spacing vernier caliper which comprises a ball measuring head, an auxiliary ruler and a main ruler. The main ruler is a right-angle component, scales are arranged on a cross rod of the main ruler, and the drop rod is a left measuring claw. The auxiliary ruler is also a right-angle component, the drop rod is a right measuring claw, the surface of the cross rod of the drop rod is provided with scales, and the main body of the auxiliary ruler is sleeved on the cross rod of the main ruler and can move left and right. The outer side surfaces of the left measuring jaw and the right measuring jaw are provided with ball measuring heads, and the two ball measuring heads are positioned on the same axis and are parallel to the cross bar of the main scale. And selecting a corresponding ball measuring head according to the size of the measured internal spline during actual measurement, and performing zero calibration according to the designed rod spacing size of the measured spline, wherein the size deviating from the zero position during actual measurement is a deviation value. The measuring tool is convenient and accurate to measure, high in efficiency, free of special requirements for environment during measurement, and particularly suitable for batch detection of the distance between the internal spline rods in a production field.
Description
Technical field
The present invention relates to a kind of length measurer, specifically, the present invention relates to a kind of special measuring tool of measuring the female spline interrod spacing.
Background technology
Inside and outside spline fitted is one of common structure in the plant equipment, and the interrod spacing of spline, odontoid and positional precision directly determine its fit quality.The interrod spacing of male splines is measured fairly simple, can accurately measure with conventional length vernier caliper, and the measurement of the interrod spacing of internal splined hole is many greatly with respect to the male splines difficulty.Prior art is measured the measurer of female spline interrod spacing and is made up of length bar and standard gauge block, during measurement length bar put into the relative teeth groove of female spline, between two length bars, insert standard gauge block, till no gap between standard gauge block and length bar, then the diameter of two length bars and the thickness of standard gauge block are added up, its accumulated value is the interrod spacing value of female spline.Although prior art can accurately be measured the interrod spacing of female spline, measuring accuracy be subjected to human factor influence big, efficiency of measurement is low, and environment is had certain requirement, the test measuring device of uncomfortable cooperation production scene bulk article.
Summary of the invention
The present invention is primarily aimed at the deficiency that prior art is measured the female spline interrod spacing, proposes a kind of simple in structure, inside spline stick space vernier caliper of measuring accurate, easy to use and direct value indication measurement result.
The present invention is achieved through the following technical solutions technical goal.
Inside spline stick space vernier caliper, it comprises ball contact tip, secondary chi and main scale.Described main scale is the square member, and its cross bar surface is provided with scale, and following plumbing bar is left measuring jaw.Described secondary chi also is the square member, and following plumbing bar is right measuring jaw, and its lateral surfaces is provided with scale, but secondary chi main body is linked in move left and right on the main scale cross bar.Improvements are: the ball contact tip that the equipped level of the left measuring jaw left side of head face of described main scale is put, the ball contact tip that the also corresponding equipped level of the right measuring jaw right side of head face of secondary chi is put.
Ball contact tip is located at the lateral surface of left measuring jaw, right measuring jaw respectively, and the bulb diameter of two ball contact tips is identical, and two ball contact tips are on the same axis, and this axis is parallel with the main scale cross bar.Select the ball contact tip of different bulb diameters for use according to the size of survey female spline, the ball contact tip of different bulb diameters significant height H value in same scope is identical, can measure under main scale cross bar identical graduation.
The present invention compared with prior art has following good effect:
1, at the left and right sides measuring jaw lateral surface ball contact tip is set, simple in structure, cost of manufacture is low;
2, value indication measurement result measures accurately, and is easy to detect;
3, measure no environment specific (special) requirements, measuring operation is simple, the efficiency of measurement height, and suitable production scene is made bulk article and is detected.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is ball contact tip structure enlarged diagrams.
Embodiment
The invention will be further described below in conjunction with embodiment and accompanying drawing.
Inside spline stick space vernier caliper shown in the drawings, it comprises ball contact tip 1, secondary chi 2 and main scale 3.The cross bar surface of described main scale 3 is provided with scale 3.2, and the following plumbing bar of main scale 3 is left measuring jaw 3.1.The cross bar surface of described secondary chi 2 is provided with scale 2.2, but secondary chi 2 is linked in move left and right on main scale 3 cross bars, and the following plumbing bar of secondary chi 2 is right measuring jaw 2.1.Equipped 1, two ball contact tip 1 of ball contact tip in the head outside of a left side measuring jaw 3.1 and right measuring jaw 2.1 is on the same axis and is parallel with the cross bar of main scale 3.It is identical to measure two used ball contact tip 1 bulb diameters of same size female spline, and the significant height H of ball contact tip 1 is identical.The present invention according to the size of tested spline, selects corresponding bulb diameter and ball contact tip 1 significant height H when actual measurement, by the design interrod spacing size of tested spline slide calliper rule are calibrated to zero-bit, and the size that departs from zero-bit during actual measurement is a deviate.Present embodiment is measured the interrod spacing of 36 groups of female splines of IVECO, and the bulb diameter of balls gauge head 1 is 3.5mm, and the effective length definite value of ball contact tip 1 is 6mm.Measurement result can directly read the interrod spacing value of measured female spline from the correspondence position of main scale 3 cross bar scales and secondary chi cross bar scale.Use inside spline stick space vernier caliper measure convenient, detection efficiency is high, and environment is not had specific (special) requirements when measuring, and is particularly suitable for doing the measurer that the production scene bulk article detects.
As the further improvement project of the present invention be: by the scale on the scale replacement cross bar, secondary chi 2 is indicated by the scale Direct Digital in the cross bar displacement of main scale 3.This scheme is measured more convenient, more accurate.
