Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to a heavy-duty long-stroke drag chain follow-up opening and closing sliding mechanism. Background Technology

[0002] Cable chains are suitable for reciprocating motion applications, especially in automated equipment such as CNC machine tools and laser cutting machine tools. They are particularly useful on large-format laser cutting machine tools, which offer advantages such as low cost and superior performance. However, because the cable chain structure involves the upper section stacked on top of the lower section, friction occurs during movement, leading to severe wear and shortened lifespan over time. The sliding mechanism works by the lower cable chain supporting the upper section, allowing it to slide on the surface of the lower chain for long-stroke movement. However, this involves sliding friction between the cable chains. Due to the high coefficient of friction, the negative effects of friction become more pronounced at higher speeds. Prolonged friction can damage cable chain links, leaving machine cables unprotected and potentially causing equipment downtime. Furthermore, the presence of sliding friction often prevents machine tools from reaching their maximum speed, as this would accelerate wear and limit processing efficiency. Summary of the Invention

[0003] The purpose of this utility model is to solve the above-mentioned technical problems by providing a novel heavy-duty long-stroke drag chain follow-up opening and closing sliding mechanism. This mechanism is suitable for situations in the automation industry where long-stroke reciprocating motion mechanisms need to install power cables, air pipes, and communication cables. During the follow-up movement, the drag chain can open and straighten with the moving mechanism to ensure that the cables inserted in the drag chain do not bend at large angles or rub against each other, thereby significantly extending the service life of the cables. It solves the problem of flexible power supply, air supply, and communication for long-distance moving mechanisms in the automation industry, and the mechanism is compact and beautiful, without occupying too much space in the equipment.
