Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coil processing, in particular to a coil processing tooling. Background Art
[0002] Motor coils are important components in motors and are usually formed by winding conductors into coil shapes. They generate force and motion through the magnetic field produced by the current in the conductors. Most of the winding of motor winding coils needs to be operated by using a winding tooling. However, for the existing winding tooling, only a through hole is opened in the middle thereof, and it is simply fixed on the rotating shaft of the winding machine by using a nut. Such a tooling is only suitable for winding coils with a smaller diameter. When winding coils with a larger diameter, the connection part between the winding tooling and the winding machine shaft is subjected to a large force and is prone to slipping. Therefore, we propose a coil processing tooling to solve the above problems. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the defect that in the prior art, when winding a winding with a larger diameter or width of the coil, the connection part between the winding tooling and the winding machine shaft is subjected to a large force and is prone to slipping, and a coil processing tooling is proposed.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A coil processing tooling includes a winding block and baffles installed on both sides of the winding block. Installation holes are opened in the middle of both baffles, and a reinforcing ring is fixed in the installation holes. The vertical cross-section of the reinforcing ring is arranged in an isosceles trapezoid shape, and a plurality of limiting grooves are circumferentially distributed on the outer surface of the reinforcing ring;
[0006] It also includes a clamping ring. An arc-shaped concave surface adapted to the reinforcing ring is opened on one side of the clamping ring, and a plurality of limiting blocks with the same number as the limiting grooves are fixed on the arc-shaped concave surface. By fixing the clamping ring on the main shaft of the winding machine, and then installing the winding tooling on the main shaft and making the reinforcing ring embedded in the clamping ring, the winding tooling is fixed.
[0007] As a preferred technical scheme of the utility model, wire arranging grooves are opened on all four sides of the baffle, and the wire arranging grooves on the two baffles are on the same straight line. The wire arranging grooves can be used to arrange the coils during the winding process.
[0008] As a preferred technical scheme of the utility model, the number of the limiting grooves is three to six, and the limiting grooves are evenly distributed around the center of the reinforcing ring, which improves the stability of the force after the limiting blocks are clamped in the limiting grooves.
[0009] As a preferred technical scheme of the utility model, key grooves are opened on the inner wall of the clamping ring, and the key grooves are arranged to facilitate the connection between the clamping ring and the main shaft of the winding machine.
[0010] The beneficial effects of the present utility model are as follows:
[0011] 1. By installing a reinforcing ring in the middle of the winding tooling and fixing a clamping ring adapted to the reinforcing ring on the winding machine, the contact area at the connection between the winding tooling and the winding machine shaft is increased through the cooperation of the reinforcing ring and the clamping ring, thereby improving the stability when winding coils with extremely large diameters.
[0012] 2. By opening wire arranging grooves around the baffle plate, the upper coils wound on the winding block can be arranged at any time through the wire arranging grooves, improving the winding quality. Description of the Drawings

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0018] Referring to Figures 1-3 , a coil processing tooling includes a winding block 1 and baffle plates 2 installed on both sides of the winding block 1. The length and width of the baffle plates 2 are both greater than the length and width of the winding block 1. The side edges of the coils wound on the winding block 1 are blocked by the baffle plates 2. At the same time, wire arranging grooves 21 are opened on all four sides of the baffle plates 2, and the wire arranging grooves 21 on the two baffle plates 2 are on the same straight line. The coils in the winding process can be arranged through the wire arranging grooves 21;
[0019] Installation holes are provided in the middle of both side baffles 2 for installing the winding tooling. A reinforcement ring 3 is fixed in the installation hole. The vertical cross-section of the reinforcement ring 3 is in the shape of an isosceles trapezoid, and a plurality of limiting grooves 31 are circumferentially distributed on the outer surface of the reinforcement ring 3. The number of the limiting grooves 31 is three to six, and the limiting grooves 31 are evenly distributed around the center of the reinforcement ring 3. After the limiting block 42 is clamped in the limiting groove 31, the stability of the force is improved. The setting that the middle of the reinforcement ring 3 is high and the edge is low can increase the contact area between the reinforcement ring 3 and the main shaft of the winding machine after installation, and further improve the stability after installation;
[0020] It further includes a clamping ring 4. An arc-shaped concave surface 41 adapted to the reinforcement ring 3 is provided on one side of the clamping ring 4. A limiting block 42 with the same number as the limiting grooves 31 is fixed on the arc-shaped concave surface 41. By fixing the clamping ring 4 on the main shaft of the winding machine, the winding tooling is installed on the main shaft again, and the reinforcement ring 3 is embedded in the clamping ring 4 to fix the winding tooling. A key groove 43 is provided on the inner wall of the clamping ring 4. The setting of the key groove 43 facilitates the connection between the clamping ring 4 and the main shaft of the winding machine.
[0021] In this embodiment: by installing the reinforcement ring 3 in the middle of the baffle 2 and fixing the clamping ring 4 adapted to the reinforcement ring 3 on the winding machine, the contact area at the connection between the winding tooling and the shaft of the winding machine is increased through the cooperation of the reinforcement ring 3 and the clamping ring 4, thereby improving the stability when winding a coil with a very large diameter.
[0022] Meanwhile, when winding the coil on the winding block 1, the wire groove 21 can timely organize the coil on the winding block 1, improving the quality of winding.
[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
