Description

Technical Field

[0001] The utility model belongs to the technical field of transformer coils, and particularly relates to a variable-diameter mobile support tooling for transformer coils. Background Technique

[0002] In the production process of precision and complex electrical equipment of transformers, as one of the core components, the processing and assembly links of coils are crucial. In order to ensure that the coils maintain a stable shape and avoid deformation or damage during processes such as winding, drying, and final assembly, it is particularly important to apply transformer coil support tooling. The support tooling not only provides necessary physical support for the coils but also ensures the smooth progress of subsequent operations, improving the production efficiency and product quality of transformers.

[0003] Figure 1 The shown support tooling is a typical design of the existing transformer coil support tooling, usually made of high-strength and corrosion-resistant materials such as high-quality steel or aluminum alloy to ensure that while bearing the weight of the coils and various forces generated during the processing, it can still maintain the structural stability and durability. In terms of design, it may include adjustable support arms, a stable base, and fixtures for facilitating the positioning and fixing of coils, etc., to meet the requirements of coils of different specifications and sizes.

[0004] In practical applications, since transformer coils are often large in volume and heavy in weight, the use of support tooling often requires multiple pieces to cooperate with each other to form a stable support system. This multi-piece combination method not only enhances the support effect but also facilitates flexible adjustment and reconfiguration according to different stages in the production process. However, before and after use, the handling work of the support tooling and the coils it carries is also a task that cannot be ignored. Traditionally, it mainly relies on manual handling by operators, which not only has a high labor intensity but also has certain safety risks. Content of the Utility Model

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

One end of the inner shaft is connected to the synchronous rotation member, and the other end of the inner shaft is connected to the shaft hole. One end of the shaft body of the inner shaft is connected to one end of a support structure, and the other end of the support structure is connected to a mobile support unit. A plurality of support structures are provided.

[0008] Further, the synchronous rotation member includes a synchronous gear and a rotating gear. The circumference of the synchronous gear meshes with the rotating gear, and one end of the inner shaft is connected to the shaft of the rotating gear.

[0009] Further, one synchronous gear is provided, and the number of rotating gears is the same as that of the support structures, and the number of support structures is greater than four.

[0010] Further, positioning holes are formed in the bottom of the support frame main body and on the synchronous gear, and positioning pins are inserted into the positioning holes.

[0017] Compared with the prior art, the present utility model has the following beneficial technical effects:

[0021] For a variable-diameter movable support tooling for a transformer coil proposed by the present utility model, when the support tooling is unloaded, it can be moved through the retractable support wheels of the movable support unit. After bearing weight, the retractable support wheels retract, and the support structure contacts the ground to bear the weight, realizing the purpose of moving and supporting the loaded coil.
