Description

Technical Field

[0001] This utility model relates to the field of starter motor manufacturing technology, and in particular to an irregularly shaped clamping structure for the rear cover of a starter motor. Background Technology

[0002] In the starter motor manufacturing process, to ensure stable rotor installation, existing technology uses a clamping plate D inserted inside the rear cover A of the starter motor. The limiting hole E on the clamping plate D fits onto the first protrusion B on the rear cover A, and the clamping plate D is further limited by the second protrusion C. The structure of the clamping plate D is as follows: Figure 3 As shown, one end of the clamping plate D presses against the rotor end face, and the rotor is clamped by the elastic deformation of the clamping plate. However, the existing clamping plate D is made of sheet metal, which is relatively heavy, and the manufacturing time and materials are large, resulting in high cost. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing top clamping plate is made of elastic plate, which is relatively heavy and costly.

[0004] To solve the above-mentioned technical problems, the present invention provides a technical solution: a starter rear cover irregular-shaped tightening structure, including a tightening ring, characterized in that: the tightening ring includes an inner circle, an outer circle and connecting segments, the inner circle and the outer circle with different diameters are arranged coaxially and connected by eight connecting segments, the inner circle and the outer circle are divided into eight segments and four segments are removed at intervals to form a tightening ring connected end to end, and the shape of the tightening ring is the same as the outer edge shape of the existing tightening plate.

[0005] Furthermore, the tightening ring is made of steel wire that is wound end to end and then welded together using a spring coiling machine.

[0006] Furthermore, the tightening ring is formed by stamping an existing tightening plate.

[0007] The beneficial effects of the utility model are:

[0008] 1. This application replaces the clamping plate in the prior art with a clamping ring with the same shape as the outer edge, thereby reducing the weight of the clamping structure and lowering the cost.

[0009] 2. In this application, the tightening ring is made of steel wire that is wound at both ends and welded together by a spring coiling machine, which realizes automated production, increases output, and reduces costs by using steel wire as raw material.

[0010] 3. The clamping ring in this application is stamped from an existing clamping plate. The excess part is cut off, thereby reducing the weight of the clamping structure and allowing the leftover material to be reused, thus reducing costs.

[0011] To make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0017] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0018] It should be understood that the steps described in the method embodiments of this utility model may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this utility model is not limited in this respect.

[0019] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example

[0020] like Figure 1-Figure 3As shown, a starter motor rear cover irregular-shaped clamping structure includes a clamping ring 1 comprising an inner circle 11, an outer circle 12, and connecting sections 13. The inner circle 11 and the outer circle 12, with different diameters, are arranged coaxially and connected by eight connecting sections 13. The inner circle 11 and the outer circle 12 are divided into eight segments, and four segments are removed at intervals to form a clamping ring 1 connected end to end. The shape of the clamping ring 1 is the same as the outer edge shape of the existing clamping plate D. By replacing the clamping plate D in the prior art with a clamping ring 1 with the same outer edge shape, the weight of the clamping structure is reduced, and the cost is lowered.

[0021] Among them, the tightening ring 1 is made by welding the ends of steel wire after coiling it with a spring coiling machine, or by stamping the existing tightening plate D. When the tightening ring 1 is made by welding the ends of steel wire after coiling it with a spring coiling machine, automated production is achieved, output is increased, and steel wire is used as raw material to reduce costs. When the tightening ring 1 is made by stamping the existing tightening plate D, the excess part is cut off, thereby reducing the weight of the tightening structure and the leftover material can be reused to reduce costs.

[0022] The process of using the overall technical solution formed by the above embodiments is as follows: the tightening ring 1 is used to replace the tightening plate D in the prior art. The two planes formed by the inner circle 11 and the outer circle 12 do not coincide, and the diameter of the outer circle 11 is larger than the diameter of the inner circle 12. The inner circle 11 of the tightening ring 1 is embedded between the first protrusion B and the second protrusion C on the rear cover A, and the outer circle 12 of the tightening ring 1 is pressed against the rotor end face.

[0023] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
