Direct-reading numerical value type wheel synthesis offset distance gauge

Abstract

The invention relates to a direct-reading numerical value type wheel synthesis offset distance gauge which comprises a base, a measuring rod, a connecting assembly and a positioning assembly; the bottom of the base is a positioning plane used for being flush with the outer plane of the spoke; the measuring rod is vertically fixed at the top of the base, and an offset value identifier is arranged on the measuring rod; the connecting assembly is connected with the measuring rod in a vertically sliding manner, the connecting assembly is provided with a horizontal indicating surface, and the indicating surface is matched with the offset distance value identifier; the positioning assembly is installed on the front side of the connecting assembly and used for enabling the indicating face to be flush with the rim width center line. The rim width center line is accurately positioned through the positioning assembly, it is guaranteed that the measuring reference is consistent with the design reference, the error caused by non-coincidence of the references is avoided, meanwhile, the wheel offset distance value can be directly measured, and the wheel offset distance detection precision is improved; in addition, the grooves and the scales can be selected as offset distance value marks, and the rapid measurement function or the specific size value measurement function can be achieved respectively.

Description

technical field [0001] The invention relates to the technical field of wheel detection, in particular to a direct-reading numerical wheel synthetic offset distance detector. Background technique [0002] The synthetic offset of the wheel needs to detect the distance from the outer plane of the wheel spoke to the centerline of the rim width. The measured value needs to be based on the centerline of the rim width. It is difficult to determine the reference line in actual measurement. Therefore, there are two main ways to measure the offset value at present. A measurement method: [0003] 1. Conversion of measurement parts, such as figure 1 As shown, the offset value H is converted to the value L measured between the outer plane of the spoke and the wheel rim. The problem with this method is: because the tolerance of the rim width is 5mm, and the tolerance of the offset is 3mm, in the process of measuring value conversion It can only be converted by the nominal size, resultin...

[0003] 1. Conversion of measurement parts, such as figure 1 As shown, the offset value H is converted to the value L measured between the outer plane of the spoke and the wheel rim. The problem with this method is: because the tolerance of the rim width is 5mm, and the tolerance of the offset is 3mm, in the process of measuring value conversion can only be converted by nominal size, resulting in inaccurate measured values

[0004] 2. Obtain the product's physical contour curve in reverse through physical scanning, and measure the offset value. This method is accurate, but requires special equipment and venues
