Background technique
Output shaft is an important component on automobile booster steering gear, it and input shaft in the case where torsion bar acts on generating
Relative rotation angular displacement becomes electric signal and is transmitted to controller, to complete real-time control power-assisted steering.It is a root long by difference
The cylindrical body of diameter forms, and torsion bar section surface is machined with four helicla flutes, between helicla flute specified location and initial angle
Angle is the significant points for transmitting rotational displacement signal.Using the center hole at output shaft both ends as the first benchmark, left end tongue
The center line of section determines the starting Angle Position of measurement, output shaft is mounted on to the top of universal tool-measuring microscope as the second benchmark
On point, the angle is measured by the rotation of the optical dividing head on universal tool-measuring microscope.The shortcomings that this measurement method is,
Second benchmark directly passes through two sidelines of measurement left end tongue, obtains its center line to determine, since left end tongue is accurate
Casting, and without sharp side, lead to angular centre of location line deviation；Using two screw thread sidelines of helicla flute itself in specified location
Two intersection points obtain center, since output shaft helicla flute is miller processing, can be broken burr removing, original point side after having milled
Bad, center is not easy to find accurately；When detecting with universal tool-measuring microscope, when crimping, will appear deviation.The above detection method needs anti-
Multiple multiple, the poor repeatability of detection, detection time is long, and detection efficiency is low.
Summary of the invention
The invention aims to overcome above-mentioned technology, provide a kind of easy to operate, detection time is short, repeated
Good, output shaft helicla flute with high accuracy angle measurement method.
The angle measurement method of output shaft helicla flute of the invention, including universal tool-measuring microscope and output shaft, feature
Be: the measuring process of the measurement method is as follows:
A1, the length for providing output shaft and angular position length；
A2, the parameter given according to A1 make aided positioning clamping apparatus, and the aided positioning clamping apparatus is ring structure, interior
The outer circumference surface clearance fit of the torsion bar section of hole and output shaft；
A3, the parameter given according to A1 select corresponding measurement steel ball；
A4, output shaft is mounted on the fixture of universal tool-measuring microscope, top is held out against output shaft (1) by the two of fixture
It is connect on fixture, and with the optical dividing head of universal tool-measuring microscope；
A5, the top position in output shaft both ends are set as the first benchmark angular position；
The measurement steel ball tangent with it is placed in A6, two V-type grooves adjacent in the tongue section of left end；
A7, the center by measuring steel ball, determine the center line of left end tongue section, and be set as the angular position of the second benchmark
It sets, i.e. starting Angle Position, and reads the initial angle angle value of starting Angle Position in the eyepiece of optical dividing head；
A8, installation aided positioning clamping apparatus, aided positioning clamping apparatus are mounted in the torsion bar section of output shaft, aided positioning clamping apparatus
Length of the left side away from output shaft left side is the radius that angular position length adds measurement steel ball；
A9, the spiral sideline that centering output shaft is replaced with the center of measurement steel ball；
A10, the optical dividing head handle by rotating universal tool-measuring microscope, when steel ball is in universal tool-measuring microscope master
In eyepiece when clearest position, in argument mirror rice wordline and steel ball it is tangent, read this in the eyepiece of optical dividing head
The difference of angle value, i.e. auxiliary angle value, initial angle angle value and auxiliary angle value is measurement angle to be measured.
The angle measurement method of output shaft helicla flute of the invention, measuring process is simple, and operation is easy, reproducible, contracting
Short detection time improves detection efficiency and detection quality, practicability and good economy performance.
