It is easy to cause the reducer gear to be directly damaged or deformed, affecting the sensor accuracy and life. In addition, there is a safety hazard that the servo motor may slip and injure people due to physical exhaustion. Another method is to use a special lifting device to directly lift the servo motor for assembly, but the lifting device is not compatible with the assembly of servo motors in different directions, and it is impossible to make the motor in a balanced state for angle adjustment. Directly using a swinging assembly may cause gear damage, affecting the transmission accuracy and life. Summary of the invention

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0017] Embodiment 1:

[0018] See also Figure 1 , Figure 1The figure shows the assembly relationship between the multi-directional lifting device 1 and the servo motor 2. The servo motor 2 is mounted on the mounting plate 101 of the multi-directional lifting device 1 by screws.

[0019] See also Figure 2 Specifically, the multi-directional hanger 1 includes a mounting plate 101, a hanging plate 102, a side hanging plate 103, a support plate 104, a rotating shaft 105, a first tapered roller bearing 107, a second tapered roller bearing 108, a pressure ring 109, a round nut 110, a vertical hanging ring 112 and a horizontal hanging ring 113.

[0020] The mounting plate 101 is used to install the servo motor. One end of the mounting plate 101 is connected to one end of the hanging plate 102 by screws, thereby forming an L-shaped structure. One end of the side hanging plate 103 is connected to one end of the support plate 104 by screws, thereby forming an L-shaped structure. The horizontal lifting ring 113 is installed on the side hanging plate 103. One end of the rotating shaft 105 is installed on the hanging plate 102 by screws. The inner rings of the first tapered roller bearing 107 and the second tapered roller bearing 108 are arranged on the step groove of the rotating shaft 105. The axis of the other end of the rotating shaft 105 is provided with a threaded hole matching with the vertical lifting ring 112, and the outer surface of the end is provided with an external thread matching with the pressing ring 109. A step hole is provided in the middle of the support plate 104, and the rotating shaft 105 passes through the step hole, and the outer ring of the first tapered roller bearing 107 is fixed on the step of the step hole. The through hole in the middle of the pressing ring 109 passes through the rotating shaft 105 and is fixed to the support plate 104 by bolts, and the pressing ring 109 presses the outer ring of the second tapered roller bearing 108. The round nut 110 is screwed into the external thread at the other end of the rotating shaft 105 and presses the inner ring of the second tapered roller bearing 108.

[0021] Specifically, a rubber pad 111 is installed by screws on the side of the hanging plate 102 close to the servo motor 2, and the rubber pad 111 is used to prevent the end face encoder of the servo motor 2 from colliding with the hanging plate 102. Preferably, a balancing block 106 for correcting the center of gravity is also installed on the support plate 104.

[0022] In this embodiment, the first tapered roller bearing 107 and the second tapered roller bearing 108 are both single-row tapered roller bearings. The outer ring of the first tapered roller bearing 107 is fixed on the step of the step hole on the support plate 104, and there is a gap between the rotating shaft 105 and the step hole on the support plate 104, and the inner ring of the first tapered roller bearing 107 is fixed in the step groove of the rotating shaft 105. The outer ring of the second tapered roller bearing 108 is fixed by the pressing ring 109, and the inner ring of the second tapered roller bearing 108 is fixed in the step groove of the rotating shaft 105 and is pressed by the round nut 110 to ensure that there is no axial stringing. There is no connection between the round nut 110 and the pressing ring 109 and there is a gap between the two. In summary, the rotating shaft 105 can drive the inner rings of the first tapered roller bearing 107 and the second tapered roller bearing 108 to rotate relative to the outer rings of the first tapered roller bearing 107 and the second tapered roller bearing 108. Thereby, the servo motor 2 can be adjusted at a small angle, ensuring that the shaft gear of the servo motor 2 and the matching gear of the robot reducer are installed in a correctly meshed state.

[0023] See also Figure 3 , vertical lifting implementation method, fix the servo motor 2 on the multi-directional lifting device 1 with screws, use the vertical lifting ring 112 as the lifting point, so that the center of gravity of the entire multi-directional lifting device 1 and the servo motor 2 is in a vertical balanced posture, and can be freely rotated at any angle in the horizontal direction around the central axis of the servo motor 2 to ensure that the shaft gear of the servo motor 2 and the adapter gear of the robot reducer are installed in the correct meshing state.

[0024] See also Figure 4 , horizontal lifting implementation method, fix the servo motor 2 on the multi-directional lifting device 1 with screws, use the horizontal lifting ring 113 as the lifting point, so that the entire multi-directional lifting device 1 and the servo motor 2 are in a horizontal balance posture with the center of gravity, and can realize free rotation at any angle in the horizontal direction around the central axis of the horizontal lifting ring 113. At the same time, it can also realize free rotation at any angle around the central axis of the servo motor 2, so that the shaft gear of the servo motor 2 and the adapter gear of the robot reducer can be installed in a correctly meshed state.
