Abstract
The invention relates to an instrument for measuring the arc tooth groove width of an internal gear and an internal spline. The instrument comprises a pair of mutually up/down wedge blocks which have flat bottoms and identical inclined angle slopes, wherein one of the inclined angle slopes is provided with a dovetail groove, and the other one is provided with a dovetail plate which is corresponding to the dovetail groove; the root portion of the dovetail plate and the tail corners of the dovetail groove are provided with grinding grooves; and the wedge block with the dovetail plate is inserted into the wedge block with the dovetail groove to form a glide pair. The instrument has the following advantages: 1) since the two mutually up/down wedge blocks form a glide pair, the two flat bottoms always remain parallel with each other no matter how the wedge blocks are moved, and thus the basic requirement of the measurement of the internal gear/the internal spline is satisfied; and 2) through the scale traces at the glide slit of the up/down wedge blocks, the distance between the two flat bottoms can be directly read, and thus accuracy and stability of the measurement are guaranteed. The instrument is novel in structure and convenient to use, and can be widely applied to authentication of inter-rod distance size of the internal gear and various internal splines and on-site batch detection in workshops.
Description
Technical field
The present invention relates to a kind of measuring instrument, especially relate to a kind of annular wheel and female spline curved tooth groove width measuring instrument.
Background technology
Involute internal gear or various female spline flank profil, reference circle place curved tooth groove width (being called for short the curved tooth groove width) are whether the inside and outside gear engagement of relation is reasonable, the whether accurate vital structural parameters of inside and outside spline fitted.Because this value is arc length, can't directly measure, after series of computation, usually with corresponding interrod spacing, indirectly measure and guarantee.The interrod spacing of existing involute internal gear and various female splines is general adopts two kinds of following methods to be measured: a kind ofly be, first the length bar of two same diameter is inserted respectively in corresponding two teeth groove of tested annular wheel or female spline, then the standard block gauge of various different sizes and size is inserted respectively between two length bars, progressively stack or minimizing, repeatedly examination gathers together and adjusts, if just with two length bars, contact the interrod spacing that these standard block gauge sums are this annular wheel or female spline; Another kind is also first the length bar of two identical diameters to be inserted in corresponding two teeth groove of tested annular wheel or female spline, directly by the distance between vernier caliper measurement two length bars.Above-mentioned two kinds of measuring methods have following weak point: 1) although the measurement of first method is more accurate, to measure efficiency too low because of too cumbersome, so is not suitable for the check of batch production; 2) measurement of second method, due to the impact that is subject to human factor, centering is poor, is difficult to measure accurately, and measuring error is very large, and particularly reproducibility error is also very large, very unstable, and measuring accuracy is difficult to reach requirement.
Summary of the invention
The objective of the invention is to provide for the prior art weak point a kind of easy to operate, measure accurately, annular wheel and female spline curved tooth groove width measuring instrument that efficiency is high.
The objective of the invention is to realize by following measures: a kind of annular wheel and female spline curved tooth groove width measuring instrument, it is characterized in that, it comprises a pair of flat, as to reach the up/down each other on inclined-plane, the same tilt angle wedge that has, wherein the inclined-plane, pitch angle of is provided with dovetail groove, the inclined-plane, pitch angle of another piece is provided with corresponding with it coattail board, the caudal horn section of the root of described coattail board and dovetail groove is provided with grinding undercut, and the wedge that is provided with coattail board inserts in the wedge that is provided with dovetail groove the slippage pair that partners.
The flat chamfering that is equipped with of the wedge of described a pair of up/down each other.
Described pitch angle is 16～24 °.
The wedge of described a pair of up/down each other has identical thickness, at the sidewall slippage seam place of up/down wedge, is carved with respectively the scale trace.
Compared with prior art, the annular wheel and the female spline curved tooth groove width measuring instrument that have adopted the present invention to propose, have following advantage: 1) two wedge of up/down slippage pairs that partner each other, in any case mobile two flatly remain parallel, have met the basic demand that annular wheel/female spline is measured; 2) the scale trace at the wedge slippage seam place of up/down, can directly read the distance of two flat, guarantees the Stability and veracity of measuring.Novel structure of the present invention, easy to use, the on-the-spot check in batches of evaluation and workshop that can be widely used in measuring annular wheel and various female spline exemplar interrod spacing sizes.

Fig. 3 a is that wedge schematic diagram, Fig. 3 b that Fig. 1 embodiment is provided with dovetail groove is Fig. 3 a B-B sectional view.
Fig. 4 is the schematic diagram of Fig. 1 examples measure female spline interrod spacing.
Embodiment
Below in conjunction with accompanying drawing, embodiment is elaborated: in the figure of one embodiment of the present of invention shown in Fig. 1～Fig. 3, a kind of annular wheel and female spline curved tooth groove width measuring instrument, it comprises: a pair of have flat, and the wedge of the up/down each other on inclined-plane, same tilt angle, wherein the inclined-plane, pitch angle of a wedge 2 is provided with dovetail groove 21, the inclined-plane, pitch angle of another piece wedge 1 is provided with corresponding with it coattail board 12, the caudal horn section of the root of described coattail board and dovetail groove is provided with grinding undercut 3, the wedge 1 that is provided with coattail board inserts in the wedge 2 that is provided with dovetail groove the slippage pair that partners.Because the up/down wedge has identical pitch angle, therefore in any case slippage, the flat of up/down wedge remains parallel.Described pitch angle is 16～24 °, preferably 20 ° of the present embodiment.
The present invention further takes following measure:
The flat chamfering that is equipped with of the wedge of described a pair of up/down each other.Due to flat be measurement plane, during measuring instrument is packed annular wheel or female spline smoothly into when measuring, the present embodiment is provided with 45 ° of chamferings of wedge thickness 1/4.
The wedge of described a pair of up/down each other has identical thickness, at the sidewall slippage seam place of up/down wedge, is carved with respectively the scale trace.The distance of wedge between flat that the scale trace is the reflection up/down, the same with micrometer callipers, can directly read two distances between flat.
The present invention is work like this: using method of the present invention as shown in Figure 4.At first by two as calculated and the identical length bar of diameter insert in measured workpiece internal tooth or corresponding two teeth groove of female spline, if the even number tooth, two length bars are symmetrical the placement relatively; If the odd number tooth, should differ from a tooth with the even number tooth and place.Then, measuring instrument is put between two length bars, the two measurement plates that relatively move, to adjust the distance of two measurement planar base surfaces.When moving to two measurement planar base surfaces and contact with two length bars respectively, by distance the reading of outside micrometer or vernier caliper measurement two measurement planes, also can read two distances between flat by measuring instrument self and scale.
The above has described embodiments of the present invention by reference to the accompanying drawings, and the structure that embodiment provides is not construed as limiting the invention, and in this area, those skilled in the art make within the scope of the appended claims various distortion or revise all in protection domain.
