Abstract
The utility model discloses an inner gear ring gear measuring fixture which comprises a base (2), a measuring instrument (5) and a tested gear ring (4), wherein a positioning bolt (1) is arranged at the bottom of the base (2) and fixes the base (2) with the measuring instrument (5); the upper surface of the base (2) is provided with a cylinder (6) matched with the tested gear ring (4); a linear opening (7) is arranged on the edge of the cylinder (6); a positioning column (3) is arranged on the edge of the linear opening (7); the tested gear ring (4) is arranged on the cylinder; and the positioning column (3) is located in the tooth space of the tested gear ring by rotating the tested gear ring (4). The inner gear ring gear measuring fixture disclosed by the utility model can accurately realize concentricity between the reference circle of the gear ring and the axle center of the measuring instrument so as to improve the detection efficiency and reduce the measurement error.
Description
Technical field
The utility model relates to a kind of ring gear gear measurement anchor clamps.
Background technology
In the production technology of automobile gear, the very important characteristic when accuracy class of bull gear is Element Design and manufacturing, the quality of this characteristic has directly had influence on the overall performance of part, to such an extent as to influence the noise and the transmission efficiency of whole variator.The accuracy class of bull gear all is to measure through gear measurement machine now; But detect with state's annular wheel detection limit appearance; At first to make the axle center of reference circle and measuring instrument of gear ring concentric, generally be through show with dial gauge with artificial adjustment with the reference circle that reaches gear ring and the concentric state in axle center of measuring instrument.So both unstable, and efficient is very low.
Summary of the invention
The utility model provides a kind of ring gear gear measurement anchor clamps, can make the axle center of reference circle and measuring instrument of gear ring concentric accurately, thereby improves detection efficiency, reduce measuring error.
The utility model has adopted following technical scheme: a kind of ring gear gear measurement anchor clamps, it is characterized in that it comprises base, measuring instrument and tested gear ring, and be provided with bolt in the bottom of base, said bolt is fixed base and measuring instrument; The upper surface of said base is provided with the cylinder that is complementary with tested gear ring; Be provided with the straight line opening at the edge of cylinder; Edge at the straight line opening is provided with reference column, and tested gear ring places on the cylinder, makes reference column be arranged in the teeth groove of tested gear ring through rotating tested gear ring.
The edge of said cylinder is arranged with three straight line openings, and the edge of each straight line opening is equipped with a reference column.
The utlity model has following beneficial effect: the utility model can directly make the axle center of reference circle and measuring instrument of gear ring concentric fast and accurately, thereby improves detection efficiency, reduce measuring error.
Description of drawings
The structural representation of Fig. 1 the utility model.
Fig. 2 is to be the vertical view of the utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model provides a kind of ring gear gear measurement anchor clamps, and it comprises base 2, measuring instrument 5 and tested gear ring 4, is provided with bolt 1 in the bottom of base 2, and said bolt 1 is fixing with measuring instrument 5 with base 2; The upper surface of said base 2 is provided with the cylinder 6 that is complementary with tested gear ring 4; Be arranged with three straight line openings 7 at the edge of cylinder 6; Be equipped with reference column 3 at the edge of each straight line opening 7; The diameter of three reference columns 3 confirms that according to the modulus calculation of different workpieces tested gear ring 4 places on the cylinder, makes reference column 3 be arranged in the teeth groove of tested gear ring through rotating tested gear ring 4.
The utility model is contained in the utility model on the main shaft of measuring instrument earlier, with the concentricity of dial gauge measured material and measuring instrument main shaft in use; The concentricity that makes the utility model and measuring instrument main shaft through adjustment is in 0.005mm; And the locking positioning bolt, tested gear ring is put on the utility model, put into a reference column respectively at three straight line centers of the utility model then; Rotate gear ring, the locking gear ring; This moment, the reference circle of gear ring was just concentric with the axle center of measuring instrument.
