In prior art, the detection of synchromesh gear hub distance over bar and gear ring radius run-out degree realizes respectively by two checkout equipments, and the lower and accuracy of detection of its work efficiency can not be guaranteed.Therefore, it is necessary for designing a kind of more rational distance over bar checkout equipment.
Below in conjunction with the elaboration that Fig. 1 to Fig. 3 carries out specifically to technical scheme provided by the invention.
As shown in Figure 1 to Figure 3, this distance over bar checkout equipment comprises:
Base plate 10, as installation matrix;
Backing plate 20, is movably arranged on the tooth hub (not shown) of putting on base plate 10 and for the level of laying, the detachable keeper be provided with for being limited in by tooth hub on backing plate 20 on turntable;
Testing agency 30, is arranged on backing plate 20 side and for realizing the comprehensive detection to tooth hub distance over bar and gear ring radius run-out degree, and during detection, the action of described testing agency 30 also records the measurement data of tooth hub.
In the present invention, above-mentioned tooth hub is preferably synchromesh gear hub, and this distance over bar checkout equipment is for the comprehensive detection of the distance over bar and gear ring radius run-out degree that realize synchromesh gear hub, and wherein distance over bar is a measurement index of reflection tooth hub reference circle transverse tooth thickness.
This distance over bar checkout equipment in an initial condition, one-piece construction is simple and each part fits is tight, in one-time detection operation, testing agency 30 can realize the comprehensive detection of distance over bar to synchromesh gear hub and gear ring radius run-out degree, namely checkout equipment not only can detect the gear ring radius run-out degree of synchromesh gear hub, also synchronously achieve the detection of the distance over bar to synchromesh gear hub, ensure that accuracy of detection and detection efficiency is high, and keeper has position-limiting action to tooth hub, when making to detect can not there is axial or circumferential displacement in tooth hub, integral device testing is steady, reliably.
For ensureing accuracy of detection, improve space layout and ensure the reliability of work and the accuracy of detection, preferred or the optional embodiment as one, testing agency 30 comprises the dial gauge 31 for comprehensive detection tooth hub distance over bar and gear ring radius run-out degree, dial gauge 31 is in being horizontally disposed with and being movably arranged on base plate 10, dial gauge 31 is coaxially provided with test rod 311 and is provided with the large knitting needle 32 vertically arranged at test rod 311 end, large knitting needle 32 is just to a teeth groove of tooth hub, dial gauge 31 and tooth hub be arranged in parallel and dial gauge 31 is positioned at above tooth hub side, during detection, test rod 311 drives large knitting needle 32 to snap in the corresponding teeth groove of tooth hub, and the circumferential lateral surface of large knitting needle 32 contacts with teeth groove two side simultaneously.
Adopt said structure layout large knitting needle 32 and dial gauge 31 closely, in time and exactly the micro-displacement of catching can be passed on dial gauge 31 and sense data, to ensure that reliability and the accuracy of testing process.
Such topology layout is ingenious, not only reliably detect distance over bar and the radius run-out degree of tooth hub, especially gear ring radius run-out degree, also improve the convenience of checkout equipment installation and removal, improve detection efficiency, it is more reliable, accurate that the dial gauge 31 of said structure layout makes to detect recorded data, decreases the error brought due to external actions such as stations.
You need to add is that: gear ring diameter run-out is in the scope that tooth hub rotates a circle, large knitting needle 32 in teeth groove or on the gear teeth with tooth depth in the middle part of with the double contact of tooth, large knitting needle 32 is relative to the maximum variation of tooth hub axial line.
The course of work of above-mentioned testing agency 30 is as follows: be first installed by dial gauge 31 and regulate zero, then the displacement of dial gauge 31 related test rod 311 is driven, the related large knitting needle of test rod 311 32 snaps in corresponding teeth groove, and dial gauge 31 just can read the comprehensive numerical value of distance over bar and the gear ring diameter run-out that will survey; Run through number, large knitting needle 32 is made to exit teeth groove to driving dial gauge 31 displacement in the other direction, then rotary teeth hub, turn over a tooth, then control dial gauge 31 large knitting needle 32 and survey the second tooth, now large knitting needle 32 stretches in the teeth groove of the second tooth, operate and so forth, turn over after a circle until tooth hub, record the data of dial gauge 31 successively, these data are comprehensive detection data.In addition, in this case, keeper coordinates closely with backing plate 20, tooth hub, and when making to measure, axial displacement and circumferential displacement can not occur tooth hub, ensure that the accuracy of surveying work.
Preferably, coordinate tightr for making large knitting needle 32 and test rod 311, improve accuracy of detection, the gauge outfit 35 with triangle through hole 351 is installed test rod 311 end is fastening, large knitting needle 32 to be fastened in triangle through hole 351 by trip bolt 36 and large knitting needle 32 is clamped at the inner at one of them angle, and trip bolt 36 to be located in gauge outfit 35 and coaxially to arrange with test rod 311.
Further, for making the layout of testing agency 30 and backing plate 20 compacter, dial gauge 31 detects more steady, in the middle part of base plate 10, preferably offer the coaxial chute 11 arranged with dial gauge 31, testing agency 30 also comprises gauge stand 33 and table cover 34, gauge stand 33 lower end to be slidably mounted on chute 11 and can along the slippage of chute 11 track straight line, table cover 34 is inserted solid in gauge stand 33 upper end, test rod 311 is located in be shown on cover 34 and is closely connected with table cover 34, test rod 311 to be arranged and vertical with gauge stand 33 with table cover 34 is coaxial, backing plate 20 lower end to be slidably mounted on chute 11 and can along the slippage of chute 11 track straight line, backing plate 20 is positioned at gauge stand 33 front and arranges near large knitting needle 32.
That is to say, test rod 311, dial gauge 31, table cover 34 are coaxially arranged, such topology layout makes testing agency 30 testing more reliable, test rod 311 activity is more flexible, smooth-going, improve accuracy of detection, and large knitting needle 32 deformation trace of backing plate 20 and detection on the same line, make operation easier, also ensure that stationarity and the reliability of testing process; And if tooth hub specification is comparatively large, then suitably can adjust the relative position of above-mentioned each parts, versatility is wider, may be used for the product detecting different size.
Further, move steadily for making testing agency 30, ensure accuracy of detection, upper position, preferred gauge stand 33 lower end to both sides respectively horizontal development be provided be resisted against on base plate 10 against plate 331, arrange against plate 331 near table cover 34 and adopt the face way of contact to be connected with base plate 10 upper surface.
Still more preferably, gauge stand 33 lower end, backing plate 20 lower end are all provided with coupling bolt 40, and the nut of coupling bolt 40 to be resisted against on base plate 10 lower surface and to adopt the face way of contact to be connected with base plate 10 lower surface.Such topology layout makes dismounting convenient, also ensure that the stability of translation.
For making equipment stable working, preferably, backing plate 20, testing agency 30 are all arranged on base plate 10 upper surface, and four, base plate 10 lower surface, edge is detachably provided with leg 50 respectively, and leg 50 end thickeies and arranges in column.When avoiding work, base plate 10 slides, and ensure that the stationarity of checkout equipment work.
