[0002] Angle grinder is a tool that uses high-speed rotating thin-blade grinding wheels, rubber grinding wheels, wire wheels, etc. to grind, cut, remove rust, and polish metal components. Figure 1 ) is the core component of the angle grinder, which is generally composed of a rotor 100, a fan blade 101, a first bearing 103, an O-ring 102, a rotating bevel gear 104, a nut 105, and a second bearing 106. During assembly, one end of the rotor 100 is installed in the second bearing 106, and the other end is installed in the first bearing 103, the O-ring 102, the rotating bevel gear 104, and the nut 105, and assembled with the gear box 107 and the gear box cover. In particular, since the rotating bevel gear 104 and the nut 105 must be assembled inside the other side of the gear box 107 facing away from the rotor, the first bearing 103 and the O-ring 102 are assembled in the bearing seat 108 of the gear box 107, so that the rotor assembly can be assembled with the gear box. However, the gear box 107 and the rotating bevel gear 104 are both extremely irregular structures, so manual assembly can only be used under the existing technology, which has low assembly efficiency and high labor costs.

[0003] The applicant's prior application for an angle grinder assembly device with publication number CN110227940A discloses an automated angle grinder assembly device: "comprising a frame, a working platform is arranged on the frame, a sliding seat assembly for fixing a rotor is arranged on the working platform, a rotating assembly is arranged above the sliding seat assembly for driving the rotor to rotate; and further comprising an angle grinder housing placement seat connected to the working platform, a guide groove is arranged on the angle grinder housing placement seat, a positioning plate is fixedly connected to the guide groove, a gear placement groove for placing a gear is arranged on the positioning plate, a sliding plate is slidably connected to the positioning plate, and a sliding plate is slidably connected to the sliding plate. The plate is placed in the guide groove, a nut placement groove is arranged on the top of the slide plate, a slide block is connected to the bottom end, the slide block is connected to the piston rod of the first cylinder, the positioning plate is connected to the piston rod of the second cylinder, a travel groove is arranged on the slide plate, the piston rod of the second cylinder passes through the travel groove, a guide rod is connected to the positioning plate, a guide hole is arranged on the side wall of the guide groove, and the other end of the guide rod passes through the travel groove and is placed in the guide hole. "Compared with traditional manual assembly, this technical solution can realize the automatic installation of the angle grinding shell and the rotor, which can significantly improve the assembly efficiency and reduce the labor cost. However, there are still the following shortcomings: 1) The rotor is placed on the sliding seat assembly and a rotating assembly is set, and the rotating assembly is provided with multiple components such as a motor and a transmission mechanism, which is heavy and lacks effective support.
