Background technology
Output shaft is a vitals on automobile booster steering gear, and it and input shaft are generation under acting in torsion bar
Relative rotation angular displacement becomes electric signal and passes to controller, so as to complete real-time control power-assisted steering.It is one long by difference
The cylinder composition of diameter, its 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 two ends as the first benchmark, left end tongue
The center line of section is used as the second benchmark, it is determined that the initial Angle Position of measurement, by output shaft the top of universal tool-measuring microscope is arranged on
On point, the angle is measured by the rotation of the optical dividing head on universal tool-measuring microscope.The shortcoming of this measuring method is,
Second benchmark directly by two sidelines of measurement left end tongue, draws its center line to determine, because left end tongue is accurate
Casting, and without sharp side, cause angular centre of location line deviation；Using two screw thread sidelines of helicla flute itself in specified location
Two intersection points obtain center, because output shaft helicla flute is miller processing, can be by burr removing after milling is complete, and original sharp side is broken
Bad, center is difficult to find accurately；When detecting with universal tool-measuring microscope, deviation is occurred during line ball.Above detection method, needs anti-
Multiple multiple, the poor repeatability of detection, detection time is long, and detection efficiency is low.
The content of the invention
The invention aims to overcome the shortcoming of above-mentioned technology, there is provided a kind of easy to operate, detection time is short, repeatability
Good, the output shaft spiral fluted angle measurement method of high precision.
The output shaft spiral fluted angle measurement method of the present invention, including universal tool-measuring microscope and output shaft, its feature
It is：The measuring process of described measuring method is as follows：

The outer circumference surface gap of the torsion bar section of output shaft coordinates；
A3, the parameter given according to A1, select corresponding measurement steel ball；
A4, by output shaft be arranged on universal tool-measuring microscope fixture on, it is top by output shaft by the two of fixture（1）Hold out against in folder
On tool, and it is connected with the optical dividing head of universal tool-measuring microscope；
A5, the top position in output shaft two ends are set to the first benchmark angular position；
The measurement steel ball tangent with it is placed in A6, adjacent two V-type grooves in left end tongue section；
A7, the center by measuring steel ball, determine the center line of left end tongue section, and are set to the second benchmark angular position,
I.e. initial Angle Position, and the initial angle angle value of initial Angle Position is read in the eyepiece of optical dividing head；
A8, installation aided positioning clamping apparatus, aided positioning clamping apparatus are arranged in the torsion bar section of output shaft, the left end of aided positioning clamping apparatus
