Description

Technical Field

[0001] This utility model relates to the field of engine and transmission assembly technology, specifically, it is a gasoline engine and transmission assembly tooling. Background Technology

[0002] Currently, in gasoline engine assembly processes, the balancing crane, as a core piece of equipment for assembling the transmission and engine, still faces significant technical bottlenecks and safety hazards in its operation. From a process execution perspective, traditional balancing crane systems use a three-point suspension lifting device for assembly transport. During assembly operations, operators must manually align the engagement position of the transmission shaft and the engine flywheel center hole by visual inspection. Due to the poor precision of the balancing crane's six-degree-of-freedom fine adjustment, coaxiality deviations frequently exceed standards during axial insertion.

[0003] In terms of operational safety, current process regulations require two operators to be responsible for the operation of the balancer and the adjustment of component postures during hoisting, respectively. This manual intervention mode requires operators to work together in a narrow work area. When the balancer suddenly stalls or the pneumatic system pressure fluctuates, the gearbox assembly will experience instantaneous displacement, which may shorten the safe distance between the operator's hand and the moving parts, posing a serious risk of mechanical pinching injury. Utility Model Content
