[0024] The scooter rear motor bearing assembly jig includes a pressing device 3, a positioning plate 1, and a positioning seat 2. Along the top-down direction, the pressing device 3, the positioning plate 1, and the positioning seat 2 are arranged in corresponding order. The motor assembly 5 includes a rear housing 51, a rear beam 52, and a connecting beam shaft 53. The two ends of the rear beam 52 are respectively assembled with the rear housing 51 and the connecting beam shaft 53. A bearing portion is formed at the connection between the rear beam 52 and the connecting beam shaft 53 for assembling a bearing member. The connecting beam shaft 53 is vertically embedded in the positioning seat 2. The positioning plate 1 has a positioning groove 11. The connecting beam shaft 53 is longitudinally arranged and embedded in the positioning groove 11. The positioning seat 2 and the positioning plate 1 are used to position the connecting beam shaft 53 synchronously. The pressing device 3 is used to apply a downward pressure, and the pressing device 3 is located above the bearing portion.

[0025] For the above-mentioned scooter rear motor bearing assembly jig, during the assembly operation, the connecting beam shaft 53 is placed on the positioning seat 2. At the same time, the connecting beam shaft 53 abuts against the positioning plate 1. Then, the bearing member is loaded onto the bearing portion. Then, the pressing device 3 moves downward to apply a downward pressure, prompting the bearing member to be assembled into the bearing portion. The automated downward pressing operation has a stable and uniform downward pressure, saving time and effort. And during the pressing operation, under the combined action of the positioning seat 2 and the positioning plate 1, the positioning of the rear housing 51 is achieved, enhancing the placement stability of the connecting beam shaft 53, thereby ensuring the alignment of the pressing device 3 with the bearing portion, improving the pressing accuracy of the bearing member, and improving the assembly qualification rate of the bearing member.

[0026] The scooter rear motor bearing assembly jig includes two guide rods 6. The two guide rods 6 are arranged at intervals correspondingly. The guide rods 6 extend longitudinally. The two guide rods 6 penetrate through the positioning plate 1 synchronously along the two ends of the positioning plate 1. The positioning groove 11 is located between the two guide rods 6. And the positioning plate 1 is fixedly arranged with the two guide rods 6.

[0027] In this way, under the action of the two guide rods 6, the assembly of the positioning plate 1 is realized, and it is convenient for the positioning plate 1 to be horizontally arranged, thereby ensuring the positioning effect of the positioning plate 1 on the coupling beam shaft 53 and improving the placement stability of the coupling beam shaft 53.
