Rear axle main speed reducer and sleeve assembly assembling equipment and assembling process thereof

The invention discloses commercial vehicle rear axle main speed reducer and sleeve assembly assembling equipment and process. A left half axle sleeve assembly and a right half axle sleeve assembly arepressed into a rear axle shell hole in a rear axle main speed reducer assembly at the same time by adopting a double-end hot pressing process. Double-end hot-pressing process equipment and a corresponding assembling process are adopted for assembling of the rear axle main speed reducer and the sleeve assembly, the problems of press-in depth fluctuation and scrap iron extrusion caused by the left-right pressure difference can be effectively solved, and the product quality stability and performance are guaranteed. 本发明公开了一种商用车后桥主减速器与套管总成装配设备及工艺，采用双头热压工艺，将左、右半轴套管总成同时压入后桥主减速器总成中的后桥壳孔内。后桥主减速器与套管总成装配采用双头热压工艺设备及相应的装配工艺，能够有效解决左、右压力差导致的压入深度波动和挤压铁屑问题，保证产品质量稳定性和性能。
