Automatic feeding assembly system for engine crankshaft and process method

Abstract

The invention discloses an automatic feeding assembly system for an engine crankshaft and a process method. The automatic feeding assembly system for the engine crankshaft comprises an engine assemblyline body and an engine tray arranged on the engine assembly line body. A cylinder body feeding workstation used for feeding an engine cylinder body, a main bearing loosening workstation used for loosening main bearing support bolts, a main bearing bush installation workstation used for main bearing bush installation and a crankshaft feeding workstation used for feeding an engine crankshaft are sequentially arranged in the conveying direction of the engine assembly line body. Two sets of feeding robots and visual systems are used for achieving automatic assembly of the crankshaft and the cylinder body, the manual carrying operation is omitted, the operation efficiency is obviously improved, the operation speed is adjustable, and the automatic assembling machine can adapt to rapid tightening.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to an engine crankshaft automatic on-line assembly system and a process method. Background technique [0002] The engine crankshaft is one of the most important parts of the engine. The chemical energy released by the combustion of fuel in the engine combustion chamber is transmitted to the crankshaft through the piston connecting rod, and the crankshaft rotates to drive other accessories of the engine to work. During the engine assembly process, the crankshaft of the engine has a complex shape and the weight of the parts is heavy. In order to reduce the labor intensity of the operator, a mechanical assist arm or a special spreader is usually used for installation. However, due to the high technical requirements and machining accuracy of the crankshaft, the spreader is used Manual installation may cause bumps on the crankshaft and damage to parts. At the same time, the engi...

Problems solved by technology

During the engine assembly process, the crankshaft of the engine has a complex shape and the weight of the parts is heavy. In order to reduce the labor intensity of the operator, a mechanical assist arm or a special spreader is usually used for installation. However, due to the high technical requirements and machining accuracy of the crankshaft, the spreader is used Crankshaft collision and parts damage occur in manual installation

At the same time, the engine bearing shell needs to be installed before the crankshaft is installed. Since the engine bearing shell needs to input the information of the main shaft hole of the cylinder block and the main journal of the crankshaft at the same time, and then match it according to the matching rules, the traditional installation method needs to establish a crankshaft conveying roller outside the assembly line. After inputting the cylinder block and crankshaft information in sequence, the crankshaft is installed, resulting in the disadvantages of low automation level and low operating efficiency during production.
