Description

Technical Field

[0001] The utility model belongs to the technical field of coiling motors, and particularly relates to an assembly structure of a coiling motor. Background Art

[0002] As Figure 1 shown, in the assembly of the existing coiling series motors, between the motor housing and the front and rear end covers, four screws arranged at equal distances in a ring cooperate with nuts for assembly, and gaskets sleeved on the outer sides of the screws are arranged between the nuts and the front and rear end covers;

[0003] For this screw and nut cooperation assembly method of the motor, it is necessary to drill holes, install screws and nuts on the motor cover plate. The assembly process is numerous, increasing the production time and complexity. Since the connection between the housing and the end cover needs to be achieved through screws and nuts, it is required that the front and rear end covers must be accurately aligned. Any slight deviation may lead to assembly difficulties or a decline in the performance of the assembled motor. The numerous processes and the requirement for precise alignment result in an increase in manufacturing costs. In addition, since this assembly method often requires manual operation, the cost of manual assembly is also a part of the manufacturing cost. Manual assembly is easily affected by factors such as the skills, fatigue, and working environment of the operators, which may all lead to insufficient assembly accuracy. Insufficient accuracy may cause the front and rear end covers to be misaligned, thus affecting the performance and safety of the motor; Content of the Utility Model

[0004] The present invention aims to solve the technical problems in the above-mentioned existing assembly method, such as numerous assembly processes, high precision requirements, high manufacturing costs, and insufficient manual assembly accuracy.

[0005] To achieve the above object, the utility model provides the following technical solution:

[0006] An assembly structure of a coiling motor, comprising a housing and two front and rear end covers, and the front and rear end covers are spirally assembled to the front and rear ends of the housing;

[0007] The front and rear end covers include a circular cover plate. One side of the circular cover plate facing the housing is provided with a convex ring, and an external thread portion is provided on the convex ring. Internal thread portions are provided on the inner side surfaces of both ends of the housing, and the front and rear end covers are assembled to the front and rear ends of the housing through the spiral cooperation of the internal thread portions and the external thread portions.

[0008] Preferably, four arc-shaped openings are annularly and equidistantly formed on the convex ring and the external thread portion. The arc-shaped openings provide points for rotation, which makes the assembly process more convenient, fast, and accurately positioned, especially in the case of no special assembly equipment.

[0009] Preferably, convex blocks protruding outward are formed between two adjacent arc-shaped openings on the convex ring and the external thread portion, and fan-shaped openings facing inward are formed on the convex blocks.

[0010] The design of the bumps and sector-shaped openings increases the structural strength of the end cap, and at the same time provides additional assembly points, further improving the assembly efficiency and convenience.

[0011] Preferably, the circular cover plate and the convex ring are integrally formed.

[0012] Preferably, the circular cover plate is provided with lead holes. The lead holes enable the wires inside the motor to pass through the inside of the cover plate smoothly and be connected to external wiring terminals or other devices.

[0013] Preferably, a number of heat dissipation holes are evenly distributed on the circular cover plate. The heat dissipation holes help to improve the heat dissipation efficiency of the motor and also provide additional gripping points and points for rotation.

[0014] Preferably, an installation sleeve for fitting and installing with the bearing seat is integrally formed at the center of the circular cover plate, and is precisely fitted with the bearing seat.

[0015] Preferably, an inverted U-shaped wire inlet hole is provided at the bottom end of the housing, which helps wires or cables to enter the motor from the bottom.

[0016] Compared with the prior art, the technical effects and advantages of the present utility model are:

[0017] For this coiling motor assembly structure, the front and rear end caps are assembled by helically mating the external thread portions thereon with the internal thread portions of the housing. This mating method utilizes the self-locking characteristic of the thread to ensure that the end caps can be firmly positioned on the housing after assembly. The arc-shaped openings and bumps on the convex ring and the external thread portions provide additional gripping and rotation points, making the assembly more convenient and accurate.

[0018] The lead holes and heat dissipation holes on the circular cover plate help with the internal wiring and heat dissipation of the motor, and can also be used as gripping points during assembly. The installation sleeve at the center of the circular cover plate is precisely fitted with the bearing seat to ensure the accurate installation and positioning of the bearing seat.

[0019] This coiling motor assembly structure does not require pre-drilling, and the front and rear end caps can be quickly assembled through spiral assembly, reducing the assembly process and time. The self-locking characteristic of the spiral fit helps to ensure the correct installation of the end caps, reducing the errors caused by manual operation, reducing the number of parts and assembly processes, and lowering the manufacturing and assembly costs.

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 shall fall within the protection scope of the present utility model.

[0027] The following is a further detailed description of the present application in conjunction with the attached Figures 2 - 4 This application embodiment discloses a rolling plate motor assembly structure, including an outer shell 1 and two front and rear end covers 2, and the front and rear end covers 2 are spirally assembled to the front and rear ends of the outer shell 1;

[0028] The front and rear end covers 2 include a circular cover plate 21. A convex ring 22 is provided on one side of the circular cover plate 21 facing the installation of the outer shell 1, and the circular cover plate 21 and the convex ring 22 are integrally formed. This integrated design reduces the number of parts, simplifies the manufacturing and assembly processes, reduces costs, and improves the rigidity and stability of the overall structure. An external thread part 23 is provided on the convex ring 22, and internal thread parts 11 are provided on the inner side surfaces of both ends of the outer shell 1. The front and rear end covers 2 are assembled to the front and rear ends of the outer shell 1 through the spiral fit of the internal thread part 11 and the external thread part 23.

[0029] Four arc-shaped openings 24 are annularly and equidistantly formed on the convex ring 22 and the external thread part 23. The arc-shaped openings 24 provide points for rotation, which makes the assembly process more convenient, fast, and accurately positioned, especially in the case of no special assembly equipment. Convex blocks 25 protruding outward are formed between two adjacent arc-shaped openings 24 on the convex ring 22 and the external thread part 23, and inward-facing sector-shaped openings 26 are formed on the convex blocks 25. The design of the convex blocks 25 and the sector-shaped openings 26 increases the structural strength of the end cover, and also provides additional assembly points, further improving the assembly efficiency and convenience.

[0030]

[0031] ​The spiral assembly method does not require pre-drilling holes. It can be directly spirally fitted through the external thread part 23 on the front and rear end covers 2 and the internal thread part 11 inside the housing 1, simplifying the processes of hole-making and assembly. Due to the adoption of spiral assembly, the front and rear end covers 2 can be more easily positioned and aligned because the self-locking characteristic of spiral fitting helps to ensure that the end covers are correctly installed on the housing 1. This assembly method reduces the errors caused by manual operation, improves the assembly accuracy, and reducing the assembly processes means reducing the production time and complexity, which helps to reduce the manufacturing cost. At the same time, due to the adoption of spiral assembly, high-precision drilling equipment may not be required, further reducing the cost.

[0032] The circular cover plate 21 is provided with a lead hole 27. The lead hole 27 enables the wires inside the motor to pass through the inside of the cover plate smoothly and be connected to external terminal blocks or other devices, which helps to simplify the internal wiring and ensure the reasonable arrangement of the wires. The bottom end of the housing 1 is provided with an inverted U-shaped wire inlet hole 12. The design of the inverted U-shaped wire inlet hole 12 helps wires or cables to enter the motor from the bottom. This design can reduce the occupation of the top space of the motor, making the design of the housing 1 of the motor more compact and beautiful.

[0033] A number of heat dissipation holes 28 are evenly distributed on the circular cover plate 21. The heat dissipation holes 28 help to improve the heat dissipation efficiency of the motor and prevent the performance degradation or damage of the motor caused by the heat generated during operation. Good heat dissipation performance also helps to improve the service life and stability of the motor. In addition, the heat dissipation holes 28 also provide additional gripping points and points for rotation. This makes the assembly process more convenient and fast, especially in the case of no dedicated assembly equipment.

[0034] An installation sleeve 29 for fitting and installing the bearing seat is integrally formed at the center of the circular cover plate 21. The design of the installation sleeve 29 is to precisely fit with the bearing seat to ensure the accurate installation and positioning of the bearing seat, improving the assembly accuracy and stability.

[0035] For the coiling motor assembly structure, the housing 1 and the two front and rear end covers 2 are assembled together by spiral assembly, which can simplify the assembly process. Due to the simplification of the assembly process, the operator can complete the assembly task faster, reducing the assembly time and improving the efficiency. In addition, due to the guiding nature of spiral assembly, the assembly process is easier to control, reducing the assembly errors caused by improper operation. Generally speaking, this spiral assembly method solves the problems existing in the traditional technology assembly method by simplifying the assembly process, improving the assembly accuracy, and reducing the manufacturing cost, thereby improving the production efficiency and product quality and reducing the uncertainty of manual assembly.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. 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.
