Mechanism for detecting poor buckling of chain

Abstract

The invention provides a chain poor buckling detection mechanism which comprises a chain wheel assembly used for installing a to-be-detected chain and a driving motor capable of driving the chain wheel assembly to rotate and further comprises a rotating support, and the rotating axis direction of the rotating support is parallel to the rotating axis direction of the chain wheel assembly. A positioning shaft, a driving assembly and a sensor are connected to the rotating support, the driving assembly is used for driving the rotating support to rotate in the circumferential direction so that the positioning shaft can be pressed on the outer side wall of the chain, and when the poor buckling point of the chain passes through the positioning shaft, the positioning shaft is driven to generate position jumping in the circumferential direction with the rotating axis of the rotating support as the center; the sensor is used for acquiring the jumping displacement of the positioning shaft. According to the chain poor buckling detection mechanism, resistance and damping in the poor buckling detection action direction are reduced to the maximum extent, and the detection precision is ensured.

Description

technical field

[0001] The invention relates to the field of automobile engine parts, in particular to a detection mechanism for poor chain buckling. Background technique

[0002] During the assembly process of the chain, due to assembly problems, for example, the chain piece is pressed too tightly, or the chain piece is deformed, or there are impurities between the various parts of the chain, etc., resulting in poor chain buckling, which hinders the flexibility of the chain and fails. normal bending. The link on the chain, when the joint rotation is not flexible, is called poor buckling or the link is inflexible, seized, the hinge is tight, or the link is stiff, etc., which is a kind of chain quality defect. To this end, it is required that there must be an effective method to detect this defect and the extent of the defect in the chain.

[0003] At present, the detection methods for poor buckling defects of chains include manual detection, machine vision detection, linea...
