Whether, when the radially limiting section of measuring stick enters into the little bearing inner race of bearing seat below completely, measuring stick stops moving down, and observes measuring unit upper surface and measuring stick intersection, see and coincide with the scale mark of standard, if overlap, represents that bearing press mounting puts in place; If do not overlap and represent that bearing press mounting does not put in place.
Advantage of the present invention:
(1) whether the present invention, by being used in conjunction with of measuring stick and measuring unit, can going out accurately fast bearing and be press-fit into place, and can meet the requirement at present product being become more meticulous day by day, and the product that can meet under the quick condition of production is again examined entirely.
(2) the present invention, by measuring stick being designed to the measurement section of different-diameter, radially limiting section and axial limiting portion, can guarantee the accuracy of accuracy of detection and testing result.
(3) the present invention by arranging many scale marks in measuring stick, and the bearing that can meet different model detects demand.In addition, can make according to tolerance the scale mark of different in width.
(4) the present invention is removably connected with limited block by the top in measuring stick, not only can prevent measuring unit landing measuring stick, make measuring unit and measuring stick not easily separated, be easy to carry and practical; Can also dismantle as required.
