This work requires the hollow shaft to be placed vertically, which poses a risk of tipping over, endangering the safety of the operators and causing damage to the workpiece. Summary of the Invention

[0003] The problem this invention aims to solve is to provide a hollow shaft anti-tipping preparation platform, overcoming the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hollow shaft anti-tipping preparation platform, including a platform, a support rod at the bottom of the platform, and an anti-tipping column and a parts storage rack on the platform.

[0005] Optionally, the surface of the platform is covered with a rubber sheet.

[0006] Optionally, the outer surface of the anti-tipping column is covered with rubber.

[0007] Optionally, the platform surface has mounting holes, which are connected to a bowl-shaped structure. The top edge of the bowl-shaped structure is fixed to the bottom surface of the platform. The mounting holes communicate with the interior of the bowl-shaped structure. The bottom surface of the bowl-shaped structure is flat. The lower end of the anti-tipping column is fixed to the bottom surface of the bowl-shaped structure. An annular groove is formed between the edge of the bowl-shaped structure and the outer wall of the anti-tipping column.

[0008] The advantages and positive effects of this utility model are: it can effectively ensure the stability of the hollow shaft during the assembly process and avoid damage to operators and workpieces caused by the hollow shaft tipping over. Attached Figure Description

[0014] The utility model will be further described in detail below in combination with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model. In the description of the utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the indicated device or element to have a specific orientation, to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. In the description of the utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two components. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0015] As shown in Figure 1 , Figure 2 The utility model provides a hollow shaft anti-toppling preparation platform, including platform 1, the bottom of platform 1 has support rod 3, and platform 1 has anti-toppling column 4 and part storage rack 5 on it;The surface of platform 1 is paved with rubber plate 2. The bottom of platform 1 is provided with support rod 3, which can make the hollow shaft placed on platform 1 away from the ground, keep the workpiece dry, and the surface of platform 1 is paved with rubber plate 2, which can avoid the hard contact of the hollow shaft with the platform 1, form protection to the workpiece, the outer surface of anti-toppling column 4 is wrapped with 5mm thick rubber, anti-toppling column 4 penetrates into the hollow shaft, which can form support to the hollow shaft on the side to avoid toppling, part storage table 5 is used for placing parts, the height of part storage table 5 can meet the needs of taking by hand during manual operation, and the size of the upper storage plate can meet the needs of storing all connecting rods and transmission pins used for single shaft assembly, the height of anti-toppling column 4 is generally 1 / 3 of the height of the hollow shaft, and the outer diameter of anti-toppling column 4 is 30mm smaller than the minimum position of the inner hole of the hollow shaft.

[0016] The hollow shaft needs to be prepared for connecting rod and transmission pin installation, and the transmission pin and connecting rod installed in the same hollow shaft have weight matching requirements, the maximum and minimum weight difference of 6 transmission pins is not more than 5g, and the maximum and minimum weight difference of 12 connecting rods is not more than 5g, and the transmission pin and the connecting rod need to be weighed and matched during the maintenance process, in order to avoid the matching confusion, the matched 6 transmission pins and 12 connecting rods are placed on the part storage table 5 after the maintenance matching; then the hollow shaft is lifted and vertically passes through the anti-toppling column 4, the connecting rod and the transmission pin installation operation is carried out, and the operator can directly take the connecting rod and the transmission pin on the part storage table 5, without the need to confirm again whether the matching is correct.

[0017] As shown in Figure 3 、 Figure 4 , the platform surface has a mounting hole, the mounting hole is connected with a bowl-shaped structure 7, the top edge of the bowl-shaped structure 7 is fixed to the bottom surface of the platform 1, the mounting hole is in communication with the inside of the bowl-shaped structure 7, the inside bottom surface of the bowl-shaped structure 7 is a plane, the lower end of the anti-toppling column 4 is fixed to the bottom surface of the bowl-shaped structure 7, and the edge of the bowl-shaped structure 7 and the outer wall of the anti-toppling column 4 form an annular groove 6, the lower end of the hollow shaft can extend into the annular groove 6, and the lower end of the hollow shaft can contact the bottom surface of the bowl-shaped structure, the purpose is to reduce the height of the top of the hollow shaft, so that the height of the arm of the worker is lowered when installing the parts, and the labor-saving effect is achieved, in addition, the inner side surface of the bowl-shaped structure 7 is an arc surface, which plays a guiding role in the process of the hollow shaft entering the annular groove 6, and the inner side surface of the bowl-shaped structure 7 surrounds the hollow shaft for one turn, which further avoids the hollow shaft from toppling to a certain extent.

[0018] The above embodiments of the present application are described in detail, but the content described is only the preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
