Multi-channel chain tight joint and missing part detection machine

Abstract

The invention discloses a multi-channel chain tight joint and missing part detection machine, which comprises a detection bench, a driving motor and a PLC control system, wherein a plurality of detection channels for allowing to-be-detected chains of different specifications to pass through for detection are arranged on the table surface of the detection bench in parallel. A dragging chain wheel used for dragging the to-be-detected chains to move, a tight joint detection mechanism, a missing roller sleeve detection mechanism and a chain sheet missing detection mechanism are correspondingly arranged on each detection channel, and the driving motor drives the dragging chain wheel to move. The method is used for highly integrated detection of missing parts and tight joints of a plurality of specifications of chains, the detection sensitivity is high, and the missing part, the tight joint and the rotation block are accurately displayed.

Description

technical field [0001] The invention relates to the technical field of chain manufacturing, in particular to a multi-channel chain tight joint and missing part detector. Background technique [0002] At present, there are the following disadvantages in the detection method of missing parts of the chain: 1. The detection of missing parts of the chain usually uses in-line contacts to correspond to the corresponding parts. For small-sized chains, especially the detection of rollers and sleeves, the sensitivity is low, and, directly The plug-in detection requires a large elastic force to press the contact piece on the parts of the chain, and the friction is large, so the contact piece is severely worn and has a short life. 2. Although the magnetic induction coil detection method has no contact with the chain, due to the non-uniformity of the chain section, the detection sensitivity for missing rollers and sleeves is not high, and it cannot directly explain what parts are missing...

2. Although the magnetic induction coil detection method has no contact with the chain, due to the non-uniformity of the chain section, the detection sensitivity for missing rollers and sleeves is not high, and it cannot directly explain what parts are missing

3. The cost of visual inspection is high
