Problems solved by technology
However, because the helical internal spline is not a straight-tooth type and has a helix angle, when testing with a standard internal diameter indicator, the probe is easy to slide from the top of the tooth to the keyway of the internal spline, and only the internal spline can be measured. The small diameter at the end face of the key cannot be measured for small diameters at other positions in the length direction of the helical inner spline, which may easily cause large errors in the size of the helical inner spline and make the part unusable

The invention relates to a device and a method for measuring the small diameter of a spiral internal spline. The device comprises an internal diameter indicator, a dial gauge and a movable measuring head are arranged at the two ends of a connecting rod of the internal diameter indicator respectively, a positioning measuring head is installed in the tail end of the movable measuring head, the central axis of the positioning measuring head is the same with that of the movable measuring head, the extending end of the positioning measuring head serves as a measuring positioning part, a tooth crestpositioning part is arranged in the middle of the measuring positioning part and abuts against a tooth crest of the measured spiral internal spline, and key groove positioning parts are symmetricallyarranged in the two sides of the tooth crest positioning part respectively and are inserted into the measured spiral internal spline. Via the measuring device, a technician can know whether the sizeof the spiral internal spline of a detected part is qualified by only determining whether a sum of the number read from the dial gauge and the small diameter of the spiral internal spline of a calibration sample ring is within the corresponding size range, operation is simple and the measuring accuracy is high.
Description
technical field [0001] The invention relates to the technical field of measuring the minor diameter of internal splines, in particular to a measuring device and method for the minor diameter of helical internal splines. Background technique [0002] Parts provided with helical internal splines are usually required in some special machines, and the minor diameter of the helical internal splines must be controlled within the range between the specified maximum size and minimum size. However, because the helical internal spline is not a straight-tooth type and has a helix angle, when testing with a standard internal diameter indicator, the probe is easy to slide from the top of the tooth to the keyway of the internal spline, and only the internal spline can be measured. The small diameter of the end face of the key cannot be measured for the small diameters at other positions in the length direction of the helical internal spline, which will easily cause a large error in the si...
