Description

Technical Field

[0001] This utility model relates to the field of idler roller processing technology, and in particular to an idler roller pressing mechanism. Background Technology

[0002] As a core load-bearing component of conveyors, idler rollers are widely used in material handling equipment in mining, ports, metallurgy, and other fields. Their structure typically consists of a roller body, bearings, seals, and a shaft. A press-fit process is required to precisely assemble the shaft and roller body to ensure the idler roller's concentricity, sealing, and load-bearing strength. Traditional idler roller press-fitting processes are mostly completed manually or with simple mechanical assistance. While some existing press-fitting equipment attempts to replace manual operation with hydraulic or pneumatic drives, problems remain, including complex structures, poor coordination of multi-directional synchronous press-fitting, and insufficient flexibility in adjusting the clamping mechanism. For example, a single-sided press-fitting mechanism struggles to achieve bi-directional synchronous press-fitting of the shaft and roller body, easily leading to assembly eccentricity. Furthermore, fixed clamping blocks cannot be dynamically adjusted according to workpiece dimensions, limiting the versatility of the press-fitting mechanism. Summary of the Invention
