Abstract

The invention discloses a comprehensive test tool for detecting the outer diameter of a stepped shaft and the inner hole of a gear, which belongs to the technical field of automobile part assembly size inspection. The comprehensive test tool comprises a positioning assembly used for stepped shaft positioning, a feeding assembly used for feeding the stepped shaft, an outer diameter measuring assembly used for measuring the outer diameter of the stepped shaft, and an inner hole measuring assembly used for detecting the inner hole of the gear. The positioning assembly, the feeding assembly, the outer diameter measuring assembly and the inner diameter measuring assembly are all installed on a bottom plate. The invention is advantageous in that the structure is simple, positioning is accurate,operation is convenient, and the measuring efficiency of the outer diameter of the stepped shaft and the inner hole of the gear is high.

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 dimension inspection of auto parts. Background technique [0002] At present, the outer diameter of the stepped shaft and the inner hole of the gear are mostly used in the field of auto parts. It is the inspection tool that must be used before the gear and the stepped shaft of the gearbox are assembled. The quality of assembly with the shaft plays a key role, and even has a great contribution to the gearbox noise index of the assembly. Existing testing equipment for testing the outer diameter of the stepped shaft and the inner hole of the gear, such as the utility model patent with the publication number CN 206160912 U, has a complex structure, no integrated testing equipment, and a low level of automation, so the number of processes is large , poor positioning accuracy, high labor co...
