Embodiment Construction
[0034] The present invention will be described in detail below in combination with specific embodiments.
[0035] see figure 1 and figure 2 A method for automatically correcting the offset of a polar coordinate gear measuring center probe, comprising the following steps:
[0036] 1) Use the double-sided involute tooth profile to correct the offset of the probe, assuming that the radius of the base circle of the involute tooth profile is r b , using an involute template or a tooth surface of a standard involute gear, assuming that the offset in the vertical direction of the R axis caused by the installation error of the probe is b 0 Offset R with R axis direction 0 ;
[0037] 2) Clamp the involute tooth profile on the rotary shaft table, and set the measuring head at a measuring position accessible to one side of the involute tooth profile, and use the polar coordinate method to measure the involute tooth profile, which can Obtain a series of points on the involute (R 1j...
