Description

Technical Field

[0001] The utility model relates to the technical field of chain detection equipment, in particular to a chain pre-tensioning and running-in machine. Background Art

[0002] Chains are generally metal links or rings, often used for mechanical transmission and traction. They consist of links, outer plates, and pins connecting the links. During the manufacturing process, the chain must first be riveted. After riveting, to ensure the quality of the chain, the chain must also be run-in and pre-tensioned to prevent the new chain from stretching and loosening after a period of use, which would affect its performance.

[0003] Existing chain processing equipment usually tests pre-tensioning and running-in separately. First, the chain is pre-tensioned. After the pre-tensioning is completed, the chain is transferred to the next process for running-in. This process is not only labor-intensive, but also easily causes unstable chain quality. At the same time, the production efficiency is low and the labor input is relatively large. Therefore, we need to propose a chain pre-tensioning and running-in machine. Utility Model Content
