Abstract
The utility model provides a testing fixture for an axial direction of a combination tooth. The fixture is characterized in that the fixture is provided with a base. A positioning plate is fixedly arranged on the base. The positioning plate is provided with a cylindrical shrinkage pool. A positioning-shaft installation hole is arranged below the axis of the shrinkage pool. A positioning shaft is inserted into the positioning-shaft installation hole. A circular convex wall arranged on the positioning shaft is clamped at the bottom surface of the shrinkage pool. A positioning sleeve is sleeved on the positioning shaft. The positioning sleeve is arranged on the circular convex wall. A workpiece is sleeved on the positioning sleeve and a ridge of a chamfering of the workpiece contacts an intersection line. The intersection line is an intersection line of the shrinkage pool on the positioning plate and the upper end face of the positioning plate. A support column is also arranged on the base. A gauge frame is sleeved on the support column in a rotatable way and the gauge frame extends towards a side direction of the support column and the tail end of the gauge frame is provided with a dial gauge. A test head of the dial gauge abuts against the end face of the workpiece. The axial testing fixture for the axial direction of the combination tooth is convenient in installation of the workpiece; in measurement, what is required is to sum a read number of the dial gauge and a standard-piece read number which is acquired in advance only so that the testing fixture is high in measurement speed, simple in procedure and high in stability.
Description
Technical field
The utility model belongs to a kind of machine work cubing, relates in particular to a kind of being exclusively used in and detects the axial dimension of locating to " fillet surface and theoretical diameter circle intersection point " in conjunction with " end face " of tooth workpiece.
Background technology

The utility model content
It is a kind of in conjunction with the axial cubing of tooth that the utility model provides, its objective is and solve the shortcoming that prior art exists, provide efficiency and the steady measurement of the axial dimension that " end face " in conjunction with tooth to " fillet surface and theoretical diameter circle intersection point " that detect automobile gearbox locate qualitative.
The utility model solves the technical scheme that its technical matters adopts:
In conjunction with the axial cubing of tooth, it is characterized in that: there is base, be installed with positioning disk on base, positioning disk offers columniform shrinkage pool, the place, axle center of shrinkage pool offers the locating shaft mounting hole downwards, and locating shaft is plugged in the locating shaft mounting hole, and the set convex annular wall of locating shaft is fastened on the bottom surface of shrinkage pool, be arranged with locating sleeve on locating shaft, locating sleeve is erected at convex annular wall top; Workpiece is set on locating sleeve, and the chamfering work piece crest line contacts with intersection, the intersection of the upper surface that this intersection is shrinkage pool on above-mentioned positioning disk and positioning disk; Also be provided with pillar on base, be arranged with rotationally dial framework on pillar, dial framework stretches out to the pillar side, and the end of dial framework is provided with dial gauge; The gauge head contact of dial gauge is on the end face of workpiece.
Usefulness of the present utility model is:
It is convenient that the utility model is installed workpiece, only need be set on locating sleeve and get final product; During measurement, only dial gauge reading and the addition of the standard component obtained in advance reading need be got final product, measuring speed is fast, and operation is simple, and stability is high.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural drawing.
Embodiment
Workpiece 1 of the present utility model be automobile gearbox in conjunction with tooth.
As shown in Figure 1, the utlity model has base 2, be installed with discoidal positioning disk 3 with screw 4 on base 2, positioning disk 3 offers coaxial columniform shrinkage pool 30, the place, axle center of shrinkage pool 30 offers coaxial locating shaft mounting hole 31 downwards, a locating shaft 5 with convex annular wall 51 is plugged in locating shaft mounting hole 31, the set convex annular wall 51 of locating shaft 5 is fastened on the bottom surface of shrinkage pool 30, be arranged with locating sleeve 6 on locating shaft 5, locating sleeve 6 is erected at convex annular wall 51 tops, a screw 8 is arranged on locating shaft 5 through pressing plate 7, and locating sleeve 6 is pressed on convex annular wall 51.
Workpiece 1 is set on locating sleeve 6, and the chamfering crest line of workpiece 1 contacts at contact point 10 places with intersection, and this intersection is shrinkage pool 30 on above-mentioned positioning disk 3 and the intersection of the upper surface 32 of positioning disk 3; Workpiece 1 is located and is erected on positioning disk 3 by locating sleeve 6 like this.
Also be provided with pillar 15 on base 2, pillar 15 is fixed on base 2 by screw 16.There is the necking segment that diameter is less on pillar 15, the necking segment position is arranged with dial framework 14 on sheathed lining 13 rotationally, the end spiral shell of pillar 15 has been provided with the Ball faced nut 17 of axial location effect, Ball faced nut 17 coordinates and is provided with ball ring 11 and rolling bearing 12, dial framework 14 contact rolling bearings 12 and being installed in rotation on pillar 15.
This justifies the axial dimension at intersection point place in conjunction with the axial cubing of tooth for detection of the end face of workpiece 1 to fillet surface and theoretical diameter.During assembling, locating shaft 5 is press fit on positioning disk 3, positioning disk 3 is connected with base 2, and locating sleeve 6 is placed on locating shaft 5, and workpiece 1 is positioned on positioning disk 3 centered by locating sleeve 6, adjusts dial gauge 9 to zero-bit.In order to measure conveniently, first manufacture a master body according to product requirement, on master body with three-dimensional coordinates measurement and indicate actual conical surface angle and actual end face is justified the axial dimension measured value at intersection point place to fillet surface and theoretical diameter.During measurement, first with master body by after dial gauge 9 zeroing, then the part 1 of knocking off measures, when the deflection reading of seeing dial gauge 9 after measurement is measured with exemplar, the position versus of table just draws measurement physical size value.
Operation steps is as follows:
(1) first assemble cubing, axial cubing is adjusted;
(2) calibration standard exemplar, take master body as benchmark, adjusts dial gauge 9 to zero-bit;
(3) workpiece 1 is inserted in to locating sleeve 6, guarantees that " the chamfering crest line of workpiece 1 " contacts with " shrinkage pool 30 holes of positioning disk 3 and the intersection of the upper surface 32 of positioning disk 3 ";
(4) rotation dial framework 14, guarantee that gauge head measures workpiece 1 end face;
(5) on dial gauge 9 and reading zero offset (have positive and negative minute) add that the end face that the reading of master body is workpiece 1 justifies the axial dimension measured value at intersection point place to fillet surface and theoretical diameter.
(6) measure completely, rotation dial framework 14, take out workpiece 1;
This has in conjunction with the axial cubing advantage of tooth: easy to detect succinct, save time (than original three-dimensional coordinates measurement, saving about 30min), improve machining precision and efficiency, and Measurement sensibility is high.This type cubing is the distance to certain end face applicable to the point in conjunction with on certain theoretical circle of tooth part fillet surface, can save a large sum of measurement expense.
