Description

Technical Field

[0001] This utility model relates to a top core, and more particularly to a fixed top core for connecting motor coils. Background Technology

[0002] During the assembly of motor coils in an exciter motor, some motor housings require a group of exciter coils to be assembled symmetrically and evenly around the circumference. In the traditional process, workers assemble them one by one by hand: after placing one exciter coil into the motor housing, they hold the exciter coil with one hand and tighten the bolts with the other hand to fix the exciter coil inside the motor housing; then they assemble the next exciter coil in the same way. This assembly method is time-consuming and labor-intensive, resulting in high labor intensity and low work efficiency for workers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the problems of the prior art and provide a fixed top core for connecting motor coils that facilitates motor coil assembly.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A fixing core for connecting a motor coil includes a core body. A through hole is provided on the central axis of the core body, and an annular groove is provided at both the upper and lower ends of the through hole. An mounting groove for assembling and fixing a gasket for the motor coil is provided on the outer circumference of the core body.

[0006] Furthermore, the annular groove is provided on the top core body on the inner circumference of the through hole.

[0007] Furthermore, the number of mounting slots is consistent with the number of motor coils to be installed, and they are evenly distributed on the outer circumference of the top core body.

[0008] Furthermore, each of the mounting slots has its upper and lower ends connected to the upper and lower end faces of the corresponding top core body.

[0009] Furthermore, the size of the fixed top core is smaller than the size of the motor housing on which the motor coil needs to be installed. The fixed top core is installed at the center of the motor housing and is concentrically set with the motor housing. At this time, the distance between the outer side of the fixed top core and the motor housing matches the size of the motor coil to be assembled.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. Place this utility model inside the motor housing where the motor coil needs to be installed. During placement, each mounting slot corresponds to the external threaded hole on the motor housing used to fix the motor coil. At this time, place all the motor coils in the predetermined position and place a washer with an internal threaded hole in the mounting slot so that the external threaded hole and the internal threaded hole are fixed on the same straight line. This makes it convenient to fix the motor coil in the motor housing later with bolts and washers. It eliminates the need for manual support of the motor coil and can secure the required motor coil in the motor housing at once, saving time and effort, reducing labor costs, and improving production efficiency.

[0012] 2. The annular groove provided in this utility model can conveniently fix the top core and use the grippers to enter and remove it from the motor housing without manual handling, which is convenient, quick, time-saving, labor-saving and labor-saving.

[0013] 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

[0019] 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.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0021] 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.

[0022] Example: Figure 1-3 As shown,

[0023] A fixing core for connecting motor coils includes a core body 1. A through hole 2 is provided on the central axis of the core body 1, and an annular groove 3 is provided on the core body 1 at both the upper and lower ends of the inner side of the through hole 2.

[0024] The outer circumference of the top core body 1 is provided with four mounting slots 4 for mounting and fixing the pads 7 of the motor coil 5. The four mounting slots 4 are evenly and symmetrically distributed on the outer circumference of the top core body 1, and the upper and lower ends of each mounting slot 4 are connected to the upper and lower end faces of the corresponding top core body 1.

[0025] The size of the fixed top core is smaller than the size of the motor housing 6 where the motor coil 5 needs to be installed.

[0026] In use, the fixing core is installed in the center of the motor housing 6 using the clamps through the annular groove 3. Each mounting groove 4 corresponds to an external threaded hole on the motor housing 6. The four motor coils 5 to be assembled are evenly installed in the gap between the core body 1 and the motor housing 6, and each motor coil 5 corresponds to a mounting groove 4. After installation, a shim 7 with an internal threaded hole is placed in each mounting groove 4. After the shim 7 is in place, the external threaded hole and the internal threaded hole are on the same straight line. At this time, the fixing core is fixed in the motor housing by its own friction and the friction between the shim and the motor coil. Without the action of external force, it will not slip out of the motor housing by its own weight. The four motor coils 5 and the corresponding shims 7 are fixed in the motor housing 6 through the external threaded hole and the internal threaded hole using the corresponding bolts. After fixing, the core body 1 is removed from the motor housing 6 using the clamps. The assembly is complete.
