[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a positioning fixture for automatic assembly of spacer sleeves, including a fixed base 1. A first disc 3 is movably connected above the fixed base 1. The top of the first disc 3 penetrates inside the conveyor belt 2. A folding plate 6 is movably connected to one side of the first disc 3. A connecting block 5 is fixedly connected to one side of the folding plate 6. A fixed ring 4 is fixedly connected below the connecting block 5;

[0022] The fixed ring 4 includes a chute 403. A fixed hook 405 is movably connected below the chute 403. A fixed rod 402 is movably connected inside the fixed hook 405. A moving sleeve 404 is fixedly connected to one side of the fixed hook 405. The top of the fixed rod 402 penetrates inside the spring 401.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown in the figure, the fixed base 1 includes a threaded rod 102. The top of the threaded rod 102 penetrates into the interior of the moving shell 108. Above the moving shell 108, a driving wheel 104 is movably connected. On one side of the driving wheel 104, a connecting belt 105 is movably connected. Inside the connecting belt 105, a driven wheel 107 is movably connected. The top of the connecting belt 105 penetrates into the interior of the moving block 106. Inside the moving shell 108, a first motor 101 is fixedly connected. Inside the moving shell 108, a second motor 103 is fixedly connected. Below the second motor 103, a second gear 110 is movably connected. On one side of the second gear 110, a first gear 109 is meshed and connected. Moreover, the external structural dimensions above the threaded rod 102 are consistent with the internal structural dimensions of the moving shell 108, and the external structural dimensions of the moving shell 108 are consistent with the internal structural dimensions of the fixed base 1. Due to the consistent dimensions between the moving shell 108 and the threaded rod 102, the moving shell 108 can move inside the fixed base 1, so that the moving shell 108 can move upward during use.

[0024] In this embodiment, as Figure 3 shown, the second gear 110 forms a rotating structure through the second motor 103, and the first gear 109 forms a rotating structure through the second gear 110. Since the second motor 103 rotates the second gear 110, and the second gear 110 rotates the first gear 109 inside the threaded rod 102, the moving shell 108 moves through the first gear 109, so that the moving shell 108 can move during use.

[0025] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, the first disc 3 forms a rotating structure through the first motor 101, and the conveyor belt 2 forms a rotating structure through the first disc 3. Since the first motor 101 rotates the first disc 3, and there are two first discs 3 movably connected to one side of the moving shell 108, and the two first discs 3 are drivingly connected through the conveyor belt 2, the first disc 3 can rotate during use.

[0026] In this embodiment, as Figure 4 shown, the fixed hook 405 forms an elastic structure through the spring 401, and the fixed hook 405 forms a sliding structure through the chute 403. Since the spacer sleeve is fixed by the fixed hook 405, the fixed hook 405 moves on the fixed rod 402 connected by the spring 401 to fix the spacer sleeve, so that the fixed hook 405 can fix the spacer sleeve during use.

[0027] In this embodiment, as Figure 1 、 Figure 2 and Figure 4As shown, the folding plate 6 forms a reciprocating structure through the first disc 3, and the fixed ring 4 and the chute 403 are of an integral structure; since the first disc 3 is connected to the fixed ring 4 through the left and right moving connecting block 5 of the folding plate 6, the fixed ring 4 can move during use.

[0028] The usage method and advantages of the present utility model: When using this positioning fixture for automatic assembly of the spacer sleeve, the working process is as follows:

[0029] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, first, the spacer sleeve is fixed through the fixed ring 4, the fixed hook 405 moves through the fixed rod 402 connected by the chute 403, and the two fixed hooks 405 are connected by a spring 401. Press the moving sleeve 404, and the fixed hook 405 can move on the fixed rod 402. The movably fixed spacer sleeve passes through the moving shell 108 above the fixed base 1, and the first disc 3 is rotated by the first motor 101. The first disc 3 drives the conveyor belt 2 to rotate, so that the two first discs 3 drive the folding plate 6 to move through the conveyor belt 2, and the folding plate 6 drives the fixed ring 4 connected by the connecting block 5 to move. The second motor 103 rotates the second gear 110, and the second gear 110 drives the first gear 109 outside the threaded rod 102 to rotate, so that the first gear 109 pushes the moving shell 108 to move upward, and the moving block 106 on the connecting belt 105 connected by the driving wheel 104 and the driven wheel 107 on one side of the moving shell 108 moves upward.
