Abstract

The invention, which relates to the automobile continuously variable transmission field, more particularly provides a precise measurement apparatus for an inner perimeter of a steel ring of a metal band as a core element for continuously variable transmission, so that a problem that it is difficult to carry out precise perimeter detection and calibrated grouping of steel rings of metal bands in the prior art can be solved. And the precise measurement apparatus, which is mainly applied to production and testing of a metal band for continuously variable transmission, comprises at least two to-be-measured component installation plates; at least one to-be-measured component installation plate is installed on a substrate by a linear guide rail or a linear bearing; the basic shape of the to-be-measured component installation plate is in a semicircular disc shape; the side surface of the to-be-measured component installation plate has at least two flanges that are distributed along a peripheral direction or two sets of projections that are respectively along the peripheral direction; and the protruding height of the at least one flange or one projection is greater than another flange or another projection. According to the precise measurement apparatus for an inner perimeter of a steel ring of a metal band as a core element, rapid detection on the inner perimeter of a steel ring can be realized, rapid grouping and assembling of the steel ring are realized, and efficiency is improved.

Description

Technical field: [0001] The invention relates to the field of continuously variable transmissions for automobiles, in particular to a precision measuring device for the inner circumference of a metal strip and steel ring, a core component of the continuously variable transmission, which is mainly used in the production and testing of the metal belt for the continuously variable transmission.
