Assembly device

The invention relates to an assembling device, the assembling device is applied to a timing chain system, the assembling device comprises a control wrench and a force application assembly, the first side of the control wrench is provided with a connecting part, and the control wrench is in attached connection with a target camshaft chain wheel in the timing chain system through the connecting part; the force application assembly is connected with the second side of the control wrench and used for applying driving force to the control wrench. According to the assembling device, the timing precision deviation caused by gaps, deformation and the like of the timing chain in the stress state can be reduced in the assembling process, and the more precise assembling effect is achieved. 本发明涉及一种装配装置，该装配装置应用于正时链条系统，装配装置包括：控制扳手和施力组件，控制扳手的第一侧设置有连接部，控制扳手通过连接部与正时链条系统中的目标凸轮轴链轮贴合连接；施力组件与控制扳手的第二侧连接，施力组件用于对控制扳手施加驱动力。本申请提供的装配装置能够在装配过程中即缩小正时链条本身在受力状态下的间隙、变形等引起的正时精度偏差，达到了更加精准装配的效果。
