Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling equipment, in particular to a rotor sleeve tooling for protecting the motor winding. Background Art

[0002] During the motor assembly process, it is a necessary process to install the motor rotor into the inner part of the wire stator with windings.

[0003] Currently, the common operation method is to use a carrying and lifting tool that can move in six directions: up and down, front and back, left and right, and continuously adjust and correct the position to install the rotor into the inner part of the wire stator.

[0004] However, during this process, it is very easy to occur that the rotor collides with the end windings of the wire stator, causing damage to the enameled wire at the end of the winding, leaving potential quality hazards, and even causing the motor to burn out. Therefore, improvement is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rotor sleeve tooling for protecting the motor winding to overcome the deficiencies in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] The present application discloses a rotor sleeve tooling for protecting the motor winding, including a tooling main body. The tooling main body is a circular ring-shaped protection structure wrapped on one side. An initial positioning structure and a secondary positioning structure are arranged inside the tooling main body. The initial positioning structure cooperates with the end ring of the rotor for positioning, and the secondary positioning structure cooperates with the rotor fan for positioning. Both the initial positioning structure and the secondary positioning structure are stepped structures. Installation holes are provided on the tooling main body.

[0008] Preferably, an installation guiding structure is provided on the outer side of the tooling main body, and the installation guiding structure cooperates with the inner wall structure of the stator for positioning.

[0009] Preferably, the installation guiding structure includes any one of an arc shape and a chamfer shape.

[0010] Preferably, the inner diameter of the inner side wall of the initial positioning structure is larger than that of the secondary positioning structure.

[0011] Preferably, the tooling main body is made of non-rigid polypropylene material.

[0012] Preferably, the secondary positioning structure includes a plurality of buffer tracks provided on the inner side of the tooling main body. Limit blocks are provided at both ends of the buffer tracks. A buffer block is movably connected to the buffer tracks. A buffer member is connected between the buffer blocks on two different inner walls of the tooling main body, and the buffer member cooperates with the rotor fan for positioning.

[0013] Preferably, the number of the buffer members is 2 - 6, and the corresponding number of buffer tracks is 4 - 12.

[0014] Advantages of the present utility model:

[0015] (1) Through the rotor sleeve tooling, the rotor is guided into the stator of the winding line. At the same time, it can prevent the rotor from directly contacting and bumping with the end of the winding, protect the end winding, and eliminate quality hazards. At the same time, through the structural design of the secondary positioning structure, the secondary positioning of the rotor end ring and the rotor blade is ensured, and the stability of the rotor sleeve and the rotor is guaranteed.

[0016] The features and advantages of the present utility model will be described in detail through embodiments in conjunction with the accompanying drawings. Description of the Drawings

[0020] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.

[0021] Embodiment 1:

[0022] Referring to Figures 1 - 2 , the embodiment of the present utility model provides a rotor sleeve tooling for protecting the motor winding, which is an integral ring-shaped structure tooling, including a fixed positioning joint surface of the inner wall and the rotor end ring, a step for secondary positioning with the rotor blade, a transition outer wall parallel to the outer diameter of the rotor, and a guiding structure with an arc-shaped end.

[0023] During the implementation process, the inner wall of the rotor sleeve and the step are both conical, and are in conical fit with the rotor end ring and the rotor blade; its beneficial effect is to ensure the secondary positioning of the rotor end ring and the rotor blade, and ensure the stability of the rotor sleeve and the rotor.

[0024] During implementation, the outer diameter D of the rotor sleeve is 0.40 - 0.50 mm larger than the outer diameter d of the matching rotor; its beneficial effect is that it can guide the rotor to be gradually inserted into the inner part of the wire stator, and the difference is smaller than the air gap between the rotor and the iron core, ensuring that the rotor sleeve and the rotor can smoothly enter the inner part of the wire stator.

[0025] It includes an installation and guiding structure 5, a conical structure for positioning with the end ring (primary positioning structure 2), and a conical structure for secondary positioning with the rotor blades (secondary positioning structure 3). The inner diameter of the rotor sleeve protection tooling fits and positions with the outer diameter of the rotor end ring, and the outer diameter is the same as the outer diameter of the rotor. Thus, through the installation and guiding structure 5, the rotor sleeve protection tooling is guided to gradually insert the rotor into the inner part of the winding iron core.

[0026] The inner and outer diameters of the tooling are related to the specifications of the motor described above.

[0027] During implementation, install the rotor sleeve onto the rotor, move the position of the rotor sleeve to fix the conical structure (primary positioning structure 2) for positioning with the end ring to the rotor end ring, and fix the conical structure (secondary positioning structure 3) for positioning with the rotor blades to the rotor blades to form secondary positioning.

[0028] During implementation, adjust the position of the rotor with the rotor sleeve so that the installation and guiding structure 5 is located at the middle position of the wire stator winding. Slowly move the rotor to make the installation and guiding structure 5 enter the winding. Continue to move the rotor, and through the transition structure on the outer wall of the rotor sleeve, guide the rotor to be inserted into the inner part of the wire stator to complete the installation operation.

[0029] Embodiment 2:

[0030] The difference technical feature between this embodiment and Embodiment 1 is that the secondary positioning structure 3 includes a plurality of buffer tracks 302 provided on the inner side of the tooling main body 1. Limiting blocks 301 are provided at both ends of the buffer tracks 302. A buffer block 303 is movably connected to the buffer tracks 302. A buffer member 304 is connected between the buffer blocks 303 on two different inner walls of the tooling main body 1. The buffer member 304 cooperates with the rotor blades for positioning.

[0031] The number of the buffer members 304 is 2 - 6, and the corresponding number of buffer tracks 302 is 4 - 12.

[0032] During use, it includes two methods. By manually adjusting the position of the buffer block 303 and replacing buffer members 304 with different lengths, the buffer area can be adjusted;

[0033] The second method is that after the rotor is connected, the buffer member 304 is pushed through contact, without fixing the position of the buffer block 303, thereby forming dynamic stability and being able to perform buffering at the same time.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
