Abstract
The utility model discloses an inner hole seam allowance angle detector for a bevel gear. The detector comprises a flat plate, a base, a core shaft, a positioning sleeve, a dial indicator, a meter frame and a V-shaped block, wherein the base and the V-shaped block are respectively arranged on the flat plate; the horizontal V-shaped block is provided with a positioning measurement mechanism consisting of the meter frame and the dial indicator; a countersink and a coaxial through hole are formed in the base; a workpiece is arranged in the countersink in the upper part; the core shaft is positioned in the through hole; an inner hole of the positioning sleeve and the core shaft are in clearance fit with each other; a small positioning sleeve and a large positioning sleeve are respectively arranged on the outer diameter of the positioning sleeve according to two diameter values of two angles of an inner hole seam allowance of the workpiece; the small positioning sleeve and the large positioning sleeve are matched with the core shaft sequentially and are axially stopped on the inner hole seam allowance of the workpiece; the dial indicator in the positioning measurement mechanism respectively measures distances from the upper end faces of the small positioning sleeve and the large positioning sleeve to the flat plate; and therefore, the angle error of the inner hole seam allowance can be judged according to a height difference. The inner hole seam allowance angle detector has a pure mechanical structure, has a low requirement on a measurement environment, is particularly suitable for configuration on the production spot and is favorable for immediate detection; and economical loss caused by batch rejection is reduced.
Description
Technical field
The utility model relates to a kind of cubing of measuring height size, and specifically, the utility model relates to a kind of bevel gear endoporus seam angle detector.
Background technology
Differential mechanism is the important component part of automobile axle, belongs to precision drive mechanism.Bevel gear drive is a kind of angle transmission, is cantilever support structure, its axial location precision determined to match meshing quality of bevel gear.Endoporus seam in the differential bevel gear is installation site axial location benchmark, and the seam end face that is among the endoporus has certain angle, and built-in seam can not directly be measured with convention amount, cubing.Contourgraph, three-dimensional coordinate measuring instrument can be used for precision measurement in the modern measure equipment, but these exact instrument are very high to the test condition requirement, and detection efficiency is very low, are only suitable for being used in control laboratory type inspection, can not be for the production of field test.Because the workshop lacks necessary cubing, the operative employee on the production line can not in time find mass deviation, so can not in time take satisfactory after correcting, easily produces the accident, economic loss of scrapping in batches.
The utility model content
The purpose of this utility model provide a kind of simple in structure, easy to operate, detection efficiency is high, measurement is accurate, be fit to production scene bevel gear endoporus seam angle detector.
The utility model is achieved through the following technical solutions technical goal.
Bevel gear endoporus seam angle detector, it comprises flat board, base, mandrel, locating sleeve, dial gauge, dial framework and V-block.Described flat board is the measuring basis plane, and base and V-block are seated in respectively on the flat board, and the V-block of prone position is equipped to form location survey mechanism by dial framework and dial gauge.Described base is provided with counterbore and coaxial through hole up, the counterbore upper surface that is in top is parallel to flat board, base leans against the one side of prone position V-block orientation angle, through hole location and installation mandrel placed in the middle, and workpiece is to treat the gaging hole seam flat base counterbore upper surface location and installation that rests up.Described locating sleeve is circular cover, endoporus and mandrel clearance fit, external diameter is made respectively little locating sleeve and large locating sleeve by two diameter values of inner hole of workpiece seam angulation, little locating sleeve, large locating sleeve are successively cooperated with mandrel and axially terminate in the inner hole of workpiece seam, the dial gauge in the location survey mechanism is measured respectively little locating sleeve, large locating sleeve upper surface is poor at a distance of the height H of flat board.
In the said structure, little locating sleeve and large locating sleeve are contour.
The utility model compared with prior art has following good effect:
1, simple and reasonable for structure, make easily, easy to operate;
2, location survey, the data obtained is accurate;
3, pure mechanical measurement mechanism is less demanding to measurement environment, is adapted at the production scene and uses.
Description of drawings
Fig. 1 is the utility model structural profile synoptic diagram.
Embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Bevel gear endoporus seam angle detector shown in Figure 1, it comprises flat board 1, base 2, mandrel 3, locating sleeve 4, dial gauge 5, dial framework 6 and V-block 7.Described dull and stereotyped 1 is measuring basis plane in the utility model, and base 2 and V-block 7 are seated in respectively on dull and stereotyped 1, and the V-block 7 of prone position is equipped with and forms location survey mechanism by dial framework 6 and dial gauge 5.Described base 2 is provided with counterbore and coaxial through hole up, the counterbore upper surface that is in top is parallel to dull and stereotyped 1, base 2 leans against the one side of prone position V-block orientation angle, through hole location and installation mandrel 3 placed in the middle, and workpiece 8 is to treat the gaging hole seam flat base 2 counterbore upper surface location and installation that rest up.Described locating sleeve 4 is circular cover, endoporus and mandrel 3 clearance fit, external diameter is made respectively little locating sleeve 4.1 and large locating sleeve 4.2 by two diameter values of workpiece 8 endoporus seam angulations, little locating sleeve 4.1, large locating sleeve 4.2 are successively cooperated with mandrel 3 and axially terminate in workpiece 8 endoporus seams, the dial gauge 5 in the location survey mechanism is measured respectively little locating sleeve 4.1, large locating sleeve 4.2 upper surfaces are poor at a distance of the height H of flat board 1.The workpiece 8 that present embodiment is measured is car differential bevel gears, and endoporus seam angle is 35
0, this angle starting point minimum diameter value Φ 22.6mm, maximum gauge value Φ 25mm.The utility model is made little locating sleeve 4.1 by external diameter Φ 22.6mm, makes large locating sleeve 4.2 by external diameter Φ 25mm.Little locating sleeve 4.1 is definite values with the semidiameter of large locating sleeve 4.2, this size is the base size of endoporus seam angle, after installing respectively, little locating sleeve 4.1 and large locating sleeve 4.2 record the height H at a distance of dull and stereotyped 1, representing two height H poor is the vertical edge physical size of endoporus seam, the deviation of this size and standard value is judged to certified products in tolerance band, otherwise is judged to unacceptable product.
