Abstract

The invention discloses a test tool used for detecting a stepped shaft outer diameter and a gear inner hole, and belongs to the technical field of automobile part assembly dimension testing. The stepped shaft outer diameter and gear inner hole comprehensive test tool comprises a locating assembly used for locating a stepped shaft, a feeding assembly used for feeding the stepped shaft, an outer diameter measuring assembly used for measuring the stepped shaft outer diameter, and an inner hole measuring assembly used for measuring the gear inner hole. The locating assembly, the feeding assembly,the outer diameter measuring assembly and the inner hole measuring assembly are installed on a bottom plate. The test tool is simple in structure, precise in location, easy to operate and high in efficiency for measuring the stepped shaft outer diameter and the gear inner hole.

Description

Technical field [0001] The invention relates to a checking tool for detecting the outer diameter of a stepped shaft and the inner hole of a gear, and belongs to the technical field of assembly size inspection of automobile parts. Background technique [0002] At present, stepped shaft outer diameter and gear inner hole inspection tools are mostly used in the field of auto parts. They are the inspection tools that must be used before the assembly of gearbox gears and stepped shafts. The quality of the assembly with the shaft plays a key role, and even has a great contribution rate to the gearbox noise index of the assembly. Existing testing equipment used to detect the outer diameter of stepped shafts and inner holes of gears, such as the utility model patent with publication number CN 206160912U, usually has a complicated structure, no integrated testing equipment, and low level of automation, so the number of processes is large. The positioning accuracy is poor, the labor cost ...
