Abstract
The invention relates to a device for measuring a distance from an annular groove to the end face of a shaft shoulder on a shaft. The device comprises a measuring ruler, a positioning rod, a locking nut and a dial indicator, wherein a boss stretching towards the longitudinal direction of the measuring ruler is arranged on one end of the measuring ruler, a through hole is arranged on the boss, the dial indicator is fixed on the boss, the axial direction of the through hole is parallel to the transverse direction of the measuring ruler, the measuring head of the dial indicator penetrates through the through hole, a mounting hole is arranged at the other end of the measuring ruler, the mounting hole is arranged along the longitudinal direction of the measuring ruler, one end of the positioning rod penetrates through the mounting hole, and the other end of the positioning rod is locked on the measuring ruler through the locking nut. The device provided by the invention has the advantage of high precision.
Description
Technical field
To the present invention relates on a kind of axle ring groove to the measurement mechanism of shaft shoulder end face distance.
Background technology
Axle, in process, can process the shaft shoulder and ring-shaped groove usually on axle.Often the distance of ring-shaped groove and shaft shoulder end face has corresponding requirements, therefore, needs to detect the distance of ring-shaped groove and shaft shoulder end face.The survey instrument of milscale one class that adopts is measured above-mentioned distance more at present, and the tolerance value required by above-mentioned distance is very little, and the error that the survey instrument of milscale one class detects is comparatively large comparatively speaking, therefore need to improve in measuring accuracy.
Summary of the invention
For above-mentioned technical matters, ring groove is to the measurement mechanism of shaft shoulder end face distance in order to provide on a kind of axle for fundamental purpose of the present invention, and the present invention has the high feature of degree of accuracy.
The technical scheme solved the problems of the technologies described above is as follows:
On axle, ring groove is to the measurement mechanism of shaft shoulder end face distance, comprise dip stick, backstay, set nut, clock gauge, one end of dip stick is provided with to the longitudinally extending boss of dip stick, after this boss is provided with through hole, this clock gauge is fixed on boss, the axis of through hole is parallel with the transverse direction of dip stick, the gauge head of clock gauge is through this through hole, the other end of dip stick is provided with mounting hole, this mounting hole is arranged along the longitudinal direction of dip stick, one end of described backstay is through mounting hole, and the other end of backstay is locked on dip stick by set nut.
Have employed such scheme, during measurement, backstay is inserted in the ring groove on axle, by the gauge head of percentage head and the end face of the shaft shoulder near, because backstay is known apart from the distance of dip stick end, record the full-scale reading on clock gauge, be exactly on axle ring groove to the distance value of shaft shoulder end face.
Described dip stick is made up of scale section and slide rule section, and slide rule section is enclosed within scale section, and slide rule section is provided with lock-screw, and slide rule section screws tight in scale section by lock-screw, and scale section and slide rule section are equipped with scale.Because the relative scale section of slide rule section can be slided, therefore, when in the face of different ring groove to the shaft shoulder end face distance time, by adjustment slide rule section, and the length of dip stick is read by the scale in scale section and slide rule section, to determine the distance of backstay apart from dip stick end, then with backstay and clock gauge cooperation, the distance of ring groove on axle to shaft shoulder end face is measured.Therefore, this spline structure can measure multiple different size axle on ring groove to the distance of shaft shoulder end face.
Accompanying drawing explanation
Fig. 1 be on axle of the present invention ring groove to the measurement mechanism structural representation of shaft shoulder end face distance;
1 is dip stick, and 1a is scale section, and 1b is slide rule section, and 2 is backstay, and 3 is set nut, and 4 is clock gauge, and 5 is boss, and 6 is lock-screw, and 7 is axle.
Embodiment
With reference to Fig. 1, on a kind of axle of the present invention, ring groove is to the measurement mechanism of shaft shoulder end face distance, comprises dip stick 1, backstay 2, set nut 3, clock gauge 4.Dip stick 1 is milscale, and one end of dip stick 1 is provided with to the longitudinally extending boss 5 of dip stick, and this boss 5 is provided with through hole, and the axis of through hole is parallel with the transverse direction of dip stick, and the gauge head of clock gauge 4 is fixed on boss through this clock gauge after this through hole.The other end of dip stick 1 is provided with mounting hole, and this mounting hole is arranged along the longitudinal direction of dip stick.One end of described backstay 2 is through mounting hole, and the other end of backstay 2 is locked on dip stick 1 by set nut 3.Described dip stick is made up of scale section 1a and slide rule section 1b, and slide rule section 1b is enclosed within scale section, and slide rule section is provided with lock-screw 6, and slide rule section screws tight in scale section by lock-screw, and scale section and slide rule section are equipped with scale.
During measurement, backstay 2 is inserted in the ring groove on axle 7, by the gauge head of percentage head 4 and the end face of the shaft shoulder near, because backstay 2 is known apart from the distance of dip stick end, record the full-scale reading on clock gauge 4, be exactly on axle ring groove to the distance value of shaft shoulder end face.
