[0003] During the assembly process of the sanding machine, workers first pre-load carbon brushes, stators and rotors and other components in the corresponding slots of the lower shell of the sanding machine. After the installation is completed, the upper and lower shells of the sanding machine are docked, and then the eccentric wheel, gasket, bottom plate and other components are manually installed on the output end of the docked sanding machine. The sanding machine has the following two problems during the assembly process. First, due to the complex structure of the sanding machine, the placement is not stable, and the carbon brushes, stators and rotors and other components need to be manually pressed into the corresponding cavity of the lower shell of the sanding machine. The corresponding components will be pulled out when the components are connected. Second, after the upper and lower shells of the sanding machine are docked, the eccentric wheel, gasket, bottom plate and other components need to be installed at the output end of the sanding machine.
