Detection tool for detecting installation angle of single pinion input shaft and press-in depth of sealing ring

Abstract

The invention discloses a detection tool for detecting the installation angle of a single pinion input shaft and the press-in depth of a sealing ring, and the detection tool comprises a detection toolouter sleeve, one end of the detection tool outer sleeve is provided with a rear cover feature groove for detecting the installation angle of the input shaft, and the interior of the detection tool outer sleeve is slidingly connected with a detection tool mandrel for detecting the press-in depth of the sealing ring. The input shaft is recognized through the input shaft feature rod, when the inputshaft feature rod recognizes the input shaft, meanwhile, the feature embedded groove is engaged with the rear cover boss, and when the detection feature surface and the rear cover feature circumferential position are located at the same reference height, the input shaft angle assembly is accurate, and otherwise, the input shaft angle assembly is inaccurate; the detection tool mandrel is matched with the detection tool outer sleeve to detect the press-in depth of the sealing ring, that is, after the detection tool outer sleeve is arranged on the outer side wall of the input shaft in a sleevingmode, one end of the detection tool mandrel abuts against the sealing ring, and the end face of the other end of the detection tool mandrel is higher than the end face of the detection tool outer sleeve, so the product is qualified, and otherwise, the assembly of the sealing ring is disqualified.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection tool for measuring the installation angle of a single pinion input shaft and the pressing depth of a sealing ring. Background technique [0002] In the process of assembling the input shaft and sealing ring of the single pinion, the assembly angle of the input shaft and the pressing depth of the sealing ring need to be controlled within the specification. However, due to the error of the manufacturing system, there will be extremely low unqualified parts. There are two ways to solve this problem: 1. Improve the accuracy of the manufacturing system to avoid the generation of unqualified parts; 2. Allow the system to produce unqualified parts, but There must be a reliable and simple screening method, which can effectively avoid the outflow of unqualified parts. However, to improve the accuracy of the system, it is necessary to invest in higher-precision equipment, wh...
