Description

Technical Field

[0001] This utility model relates to the field of commutator technology, specifically to a combined commutator. Background Technology

[0002] Commutator segments are key conductive components in the commutator of DC motors. They automatically switch the direction of the current flowing through the rotor coils at the appropriate time, thereby ensuring that the rotor continuously receives torque in the same direction in the magnetic field, enabling the motor to rotate continuously. Their core function is to convert external DC power into a periodically changing current in the rotor coils, completing the "commutation" process and maintaining stable motor operation.

[0003] However, existing commutator segments require a figure-seven machining process during use, making assembly difficult and resulting in material waste. Therefore, those skilled in the art have provided modular commutator segments to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a combined commutator segment to solve the problems mentioned in the background art.

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

[0006] A modular commutator includes a fixed mounting block, a connecting frame fixed to the bottom of the fixed mounting block, a positioning block fixed to the top of the fixed mounting block, an upper mounting sleeve movably sleeved on the outer side of the positioning block, a positioning groove opened inside the upper mounting sleeve, a combination mechanism provided on the outer side of the fixed mounting block and the upper mounting sleeve, and a limit mechanism provided on the outer side of the fixed mounting block and the upper mounting sleeve.

[0007] As a further embodiment of this utility model: the combined mechanism includes a lower fixed sleeve, a reinforcing sleeve fixed to the bottom of the lower fixed sleeve, a lower half-threaded post fixed to the outer side of the lower fixed sleeve, an upper fixed sleeve installed on the outer side of the upper mounting sleeve, an upper half-threaded post fixed to the outer side of the upper fixed sleeve, a washer movably sleeved on the outer side of the upper half-threaded post and the lower half-threaded post, and a connecting nut threadedly connected to the outer side of the upper half-threaded post and the lower half-threaded post.

[0008] As a further embodiment of this utility model: the limiting mechanism includes a fixed pad, a guide slider is slidably connected to the outside of the fixed pad through a sliding groove, a movable sleeve is fixed to the outside of the guide slider, a handle pad is fixed to the outside of the movable sleeve, a limiting pad is installed at the bottom of the upper mounting sleeve, a limiting sleeve is fixed to the outside of the limiting pad, a positioning threaded rod is fixed to the outside of the limiting pad, and a positioning nut is threaded to the outside of the positioning threaded rod.

[0009] As a further improvement of this utility model, a limiting hole is provided inside the limiting sleeve, and the size of the limiting hole is adapted to the size of the movable sleeve.

[0010] As a further embodiment of this utility model: the fixing pad and the fixing mounting block are fixedly connected, and the movable sleeve is movably sleeved on the outside of the positioning threaded rod.

[0011] As a further embodiment of this utility model: the lower fixing sleeve and the fixing mounting block are fixedly connected, and the reinforcing sleeve and the fixing mounting block are fixedly connected.

[0012] As a further improvement of this utility model: the radius of the lower half threaded post is equal to the radius of the upper half threaded post, and the outer side of the connecting nut is provided with anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The fixed mounting block and connecting frame of this device can use high-strength structural steel as the basic load-bearing components to ensure structural stability. The upper mounting sleeve, as a wear-prone component, can be made of wear-resistant conductive material, with its performance optimized separately. This avoids the use of high-cost alloys as a whole, and the assembly is stable and simple, thus achieving the goal of saving costs.

[0015] 2. This device is equipped with a combination mechanism. When combining the fixed mounting block and the upper mounting sleeve, the upper mounting sleeve is movably sleeved on the outside of the positioning block, so that the corresponding surfaces of the lower fixed sleeve on the outside of the fixed mounting block and the upper fixed sleeve on the outside of the upper mounting sleeve fit together. This facilitates the combination and assembly of the fixed mounting block and the upper mounting sleeve. The assembly process is simple and ensures the consistency of the shape and size of the commutator segment after combination.

[0016] 3. By setting a limiting mechanism, when the fixed mounting block and the upper mounting block are assembled, the corresponding surface of the limiting pad on the outside of the upper mounting sleeve is attached to the outside of the connecting frame, which facilitates the fixing between the movable sleeve and the limiting pad. This allows the upper mounting sleeve and the fixed mounting block to be limited on the outside after they are connected, ensuring the stability of the connection structure.

[0025] The working principle of this utility model is as follows: When using this device, the upper mounting sleeve 4 is movably sleeved on the outside of the positioning block 3 when the fixed mounting block 1 and the upper mounting sleeve 4 are combined. This facilitates the combination and assembly of the fixed mounting block 1 and the upper mounting sleeve 4. The assembly process is simple to operate.

As an easily worn part, the upper mounting sleeve 4 can be made of wear-resistant conductive material to optimize its performance, avoiding the use of high-cost alloys as a whole. Moreover, the assembly is stable and simple, achieving the goal of saving costs.

[0026] Example 2

[0027] Please see Figure 2-4 In this embodiment of the utility model, the combined commutator includes a fixed mounting block 1, characterized in that a connecting frame 2 is fixed at the bottom of the fixed mounting block 1, a positioning block 3 is fixed at the top of the fixed mounting block 1, an upper mounting sleeve 4 is movably sleeved on the outside of the positioning block 3, a positioning groove 5 is provided inside the upper mounting sleeve 4, a combination mechanism 6 is provided on the outside of the fixed mounting block 1 and the upper mounting sleeve 4, and a limit mechanism 7 is provided on the outside of the fixed mounting block 1 and the upper mounting sleeve 4.

[0028] The combined mechanism 6 includes a lower fixed sleeve 61, a reinforcing sleeve 62 fixed to the bottom of the lower fixed sleeve 61, a lower half-threaded post 63 fixed to the outside of the lower fixed sleeve 61, an upper fixed sleeve 64 installed on the outside of the upper mounting sleeve 4, an upper half-threaded post 65 fixed to the outside of the upper fixed sleeve 64, a washer 66 movably sleeved on the outside of the upper half-threaded post 65 and the lower half-threaded post 63, a connecting nut 67 threadedly connected to the outside of the upper half-threaded post 65 and the lower half-threaded post 63, the lower fixed sleeve 61 and the fixed mounting block 1 fixedly connected, the reinforcing sleeve 62 and the fixed mounting block 1 fixedly connected, the radius of the lower half-threaded post 63 and the radius of the upper half-threaded post 65 are equal, and the outside of the connecting nut 67 is provided with anti-slip texture.

[0029] In one embodiment of this utility model, the limiting mechanism 7 includes a fixed pad 71, a guide slider 72 slidably connected to the outside of the fixed pad 71 via a sliding groove, a movable sleeve 73 fixed to the outside of the guide slider 72, a handle pad 74 fixed to the outside of the movable sleeve 73, a limiting pad 75 installed at the bottom of the upper mounting sleeve 4, a limiting sleeve 76 fixed to the outside of the limiting pad 75, a positioning threaded rod 77 fixed to the outside of the limiting pad 75, a positioning nut 78 threadedly connected to the outside of the positioning threaded rod 77, a limiting hole opened inside the limiting sleeve 76, the size of the limiting hole being adapted to the size of the movable sleeve 73, the fixed pad 71 and the fixed mounting block 1 being fixedly connected, and the movable sleeve 73 being movably sleeved on the outside of the positioning threaded rod 77.

[0030] The working principle of this utility model is as follows: This device is equipped with a combination mechanism 6. When combining the fixed mounting block 1 and the upper mounting sleeve 4, the upper mounting sleeve 4 is movably sleeved on the outside of the positioning block 3, so that the corresponding surfaces of the lower fixing sleeve 61 on the outside of the fixed mounting block 1 and the upper fixing sleeve 64 on the outside of the upper mounting sleeve 4 are in contact. At this time, the lower half threaded post 63 on the outside of the lower fixing sleeve 61 and the upper half threaded post 65 on the outside of the upper fixing sleeve 64 form a complete threaded rod. Then, the washer 66 is movably sleeved on the outside of the upper half threaded post 65 and the lower half threaded post 63, and the connecting nut 67 is threadedly connected to the lower half threaded post 63 and the upper half threaded post 65, thus conveniently completing the connection between the fixed mounting block 1 and the upper mounting sleeve 4. The combination and assembly process is simple and ensures the consistency of the shape and size of the commutator segments after assembly. By setting a limit mechanism 7, after the fixed mounting block 1 and the upper mounting sleeve 4 are assembled, the corresponding surface of the limit pad 75 on the outside of the upper mounting sleeve 4 is attached to the outside of the connecting frame 2. Then, the handle pad 74 is turned to drive the guide slider 72 and the moving sleeve 73 to move, so that the moving sleeve 73 passes through the limit sleeve 76. After the moving sleeve 73 is movably sleeved on the outside of the positioning threaded rod 77, the positioning nut 78 is threadedly connected to the positioning threaded rod 77, which facilitates the fixing between the moving sleeve 73 and the limit pad 75. This allows the upper mounting sleeve 4 and the fixed mounting block 1 to be limited on the outside after connection, ensuring the stability of the connection structure.
