[0002] Excavator, also known as excavation machinery, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and loads them into transport vehicles or unloads them to a stockpile. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loose soil and rock. From the development of engineering machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important engineering machinery in engineering construction. The swing motor is an actuator of the hydraulic system. It converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft, which is used in the power system of the excavator. When assembling the swing motor, due to the large number of parts of the swing motor, it is usually necessary to lift the swing motor for assembly. The traditional auxiliary assembly device is usually assembled with the swing motor placed horizontally. Due to the heavy assembly parts, the operator needs to consume a lot of physical strength during assembly, and the assembly efficiency is not high. At the same time, the traditional auxiliary assembly device is mostly customized for one model. One tool is not very applicable. When assembling multiple models of swing motors, it is necessary to frequently replace the tool, which increases the cost and reduces the efficiency. Utility Model Content
