The utility model in order to the technical scheme solving its technical matters and adopt is: a kind of hub bearing inner ring ditch position measuring mechanism, comprise mo(u)ld top half, lower core barrel, measuring pen, survey sub-guide rod and standard steel ball, described lower core barrel upper end forms the location structure for placing and locate inner ring, mo(u)ld top half longitudinally can slide and be positioned directly over lower core barrel, the stepped hole that lower end diameter is greater than upper end diameter is formed inside mo(u)ld top half, standard steel ball be able to be located in the raceway groove outside inner ring to be measured, the step surface in mo(u)ld top half inner side step hole and the large lower end sidewall of diameter are just tight against on the upside of standard steel ball and outer surface, survey sub-guide rod longitudinally can slide and be inserted in mo(u)ld top half, survey sub-lower end of the guide rod and can be tight against inner ring upper end face to be measured, measuring pen is fixedly installed on mo(u)ld top half, under measuring pen, terminal contacts can contact and survey sub-guide rod upper surface.

As further improvement of the utility model, be also provided with survey submounts, survey submounts lower end and be fixedly installed on mo(u)ld top half, survey submounts upper end edge horizontal direction and extend to directly over mo(u)ld top half, measuring pen is fixedly installed in be surveyed on submounts.

As further improvement of the utility model, described measuring pen, survey sub-guide rod and lower core barrel is coaxial.

As further improvement of the utility model, the location structure of described lower core barrel upper end is the inverted T-shaped structure that diameter inside contracts, lower core barrel upper end diameter inside contracts position and be able to be inserted in bearing inner race to be detected, and bearing inner race lower end to be detected is just tight against on the annular table terrace of lower core barrel upper end formation.

As further improvement of the utility model, the step surface in described mo(u)ld top half inner side step hole is the dip plane of inside height higher than outside height.

The beneficial effects of the utility model are: mo(u)ld top half inner side step hole of the present utility model and bearing outer ring ditch position similar, compression standard steel ball is mated in itself and bearing inner race ditch position to be detected, bearing inner race is made to be in actual assembled state, now by measuring pen, the sub-guide rod upper end position of the survey being pressed in bearing inner race upper end is measured, accurately can obtain bearing inner race ditch bit data, especially in mo(u)ld top half rotation status, measuring accuracy is high, can the excessive unacceptable product of Timeliness coverage inner ring list product ditch position error, cause finished product defective after avoiding assembling, effectively reduce bearing completed products disqualification rate and scrappage, reduce bearing mnanufacture cost.
