Abstract: By analyzing the process of heavy commercial vehicle chassis assembly line and combining with the structural characteristics of the front axle assembly of heavy commercial vehicles, a work platform has been developed to achieve automatic flipping of the front axle assembly of heavy commercial vehicles. This automatic flipping platform can eliminate safety hazards during manual flipping, improve labor productivity, and integrate the positioning, assembly, and flipping of the current front axle assembly into one platform, shortening the process time from 6 minutes to 5 minutes, improve the automation level of the assembly line and achieve increased production capacity.

Key words: Flipping platform; Positioning and clamping system; Logic control elements; Double acting cylinder

摘要： 通过对重型商用车底盘装配线进行工艺分析，结合重型商用车前桥总成结构特点，研 制了一种实现重型商用车前桥总成自动翻转的工作平台，该自动翻转平台能够消除人工翻转 时存在的安全隐患，提高劳动生产率，将目前的前桥总成定位装配、翻转合为一个平台完成， 工序节拍由 6 分钟缩短为 5 分钟，既提高装配线自动化程度又实现产能提升。
