Single detection type axle main pin hole inner sleeve detection device with double inner sleeve wall thickness comparison channels

Abstract

The invention relates to a single detection type axle main pin hole inner sleeve detection device provided with double inner sleeve wall thickness comparison channels, and the device comprises a lower comparison disc, an upper comparison disc, a rotating structure which drives the lower comparison disc to rotate, a pressing structure, a supporting plate, and a bottom plate. An ejector rod penetrates through the lower comparison disc, the lower end of the upper comparison disc is provided with a vertical connecting shaft which is arranged on the lower comparison disc in a pluggable and penetrating mode, the vertical connecting shaft is provided with a conical surface section which abuts against an ejector rod, one end of the ejector rod is provided with an elastic layer, a vertical round pin is sleeved with a base plate which is supported on the supporting plate through a spring, and the base plate is provided with two inner sleeve wall thickness comparison channels; and when the inner sleeve of which the inner diameter and the wall thickness meet the design values is sleeved on the lower comparison disc, the inner sleeve wall thickness comparison channel can move to be aligned with the wall of the inner sleeve in the vertical direction. The device has the advantages of being capable of detecting the inner diameter and conveniently detecting whether the wall thicknesses of all positions in the circumferential direction meet the requirement or not, and the problem that the wall thicknesses and the inner diameters of the inner sleeves on the two sides are troublesome is solved.

Description

[0001] This application is the application number 201910658142X, the application date is July 20, 2019, and the name is a divisional application of the name "Single-inspection axle kingpin hole inner sleeve detection device with double inner sleeve wall thickness comparison channel". technical field [0002] The invention relates to a testing tool for vehicle axle testing, in particular to a single-check testing device for the inner sleeve of the kingpin hole of the axle with double inner sleeve wall thickness comparison channels. Background technique [0003] The axle of the car has a front axle and a rear axle, wherein the front axle is used to install the front wheels, support the weight of the front of the car, and connect with the frame with the front suspension. In Chinese patent application number 2011201792654, the authorized announcement date is December 28, 2011, and promptly discloses a kind of automobile front axle of existing structure in the patent document of n...

AI Technical Summary

Problems solved by technology

The original front axle of the car had the following disadvantages: the crossbar and the cantilever were of a split structure and were connected together by welding, so the position between the cantilever and the crossbar was prone to deviation and did not meet the requirements, resulting in a low yield rate; for This company made improvement and designed the name "automobile front axle with flat bottom casting structure"; but the axle of this casting structure has the following disadvantages: the king pin hole is prone to wear and tear, resulting in the scrapping of the front axle

Existing detection of the wall thickness and inner diameter of the inner sleeve is done by different detection mechanisms, which is troublesome to detect; the detection of wall thickness is determined by detecting multiple points in the circumferential direction of the inner sleeve with a vernier caliper. Since the detection points are There are a limited number of them. When the places that do not meet the requirements are not sampled, there will be misjudgments and the accuracy of detection will be poor.
