According to the technical scheme, the position of the wheel is positioned by arranging the first positioning part and the second positioning part, so that the first rim contact 32, the second rim contact 41, the first rim contact 31 and the second rim contact 51 are always positioned at preset positions, the consistency of the positions detected each time is ensured, and the accuracy of measurement is further ensured; further, the third measuring rack 50 is clamped into the second measuring rack 40 through the matching of the second limiting part 52 and the first limiting part 42, and the first measuring rack 30 and the third measuring rack 50 are moved to enable the first rim contact 31 and the second rim contact 51 to be abutted against the rim of the measured wheel, so that the relevant data of the rim are measured; through removing first measuring rack 30 and second measuring rack 40, make first rim contact 32 and second rim contact 41 and the rim butt of the wheel of surveying, and then measure the relevant data of rim, thereby realize that a measuring equipment just can simultaneous measurement rim and rim, the simple corresponding measuring rack that only needs to remove of concurrent operation, thereby the measurement of efficiency of wheel rim flange measuring apparatu has been improved greatly, only need obtain the relevant data through displacement sensor simultaneously and calculate and can obtain the relevant data of rim and rim, and then improved measurement accuracy, the precision error that manual reading leads to has been reduced.
It can be understood that, in the present embodiment, only the displacement sensors need to be installed on the first measuring rack 30 and the third measuring rack 50, because the third measuring rack 50 can slide relative to the second measuring rack 40, if rim data is measured, only the first limiting portion 42 needs to be limited in the second limiting portion 52, so that the third measuring rack 50 is limited on the second measuring rack 40, and through the fixed distance between the first limiting portion 42 and the second rim contact 41 and the fixed distance between the second limiting portion 52 and the second rim contact 51, only the displacement amount in the displacement sensor on the third measuring rack 50 needs to be read, and then corresponding data can be obtained through a calculation method described later; therefore, the installation of the displacement sensor is reduced, and the energy consumption and the production and manufacturing cost of the wheel rim and rim measuring instrument are reduced.
Specifically, one of the first position-limiting portion 42 and the second position-limiting portion 52 is a position-limiting protrusion, and the other is a position-limiting hole, and when the thickness and the height of the rim are measured, the position-limiting protrusion is limited in the position-limiting hole; the second measuring frame 40 is provided with a limiting protrusion, the third measuring frame 50 is provided with a limiting hole, it should be noted that the limiting protrusion should have a certain deformability, and when the third measuring frame 50 slides along the second measuring frame 40, the limiting protrusion deforms to a certain extent so that the limiting protrusion is clamped into the limiting hole; when the third measuring frame 50 needs to be pulled out of the second measuring frame 40, force is only required to be applied to the third measuring frame 50 to enable the limiting protrusions to deform and be pulled out of the limiting holes; of course, in other embodiments, the first position-limiting portion 42 and the second position-limiting portion 52 may also be configured as a hook and a slot, when measuring the relevant data of the rim, the hook is clamped into the slot to limit the third measuring rack 50 in the second measuring rack 40, and when needing to be separated, the hook is separated from the slot.
