Description

Technical Field

[0001] This utility model belongs to the field of motor stator winding technology, specifically relating to a clamp for motor stator winding. Background Technology

[0002] Motor stator winding refers to the process of winding conductors (usually copper or aluminum wires) into the slots of the motor stator according to specific rules and shapes to form coils. This is an important step in motor manufacturing because the quality of the winding directly affects the performance, efficiency, and reliability of the motor. Currently, specialized motor stator winding fixtures are required.

[0003] Publication number: CN 207994871 A motor stator winding clamp, U, is equipped with a locking device, which includes a frame mounting base. The frame mounting base has a mounting hole at the center of its upper surface that mates with the stator frame. The height of the mounting hole is the same as the height of the stator frame. Symmetrical pressure plate supports are fixedly connected to the frame mounting base on both sides. One end of each pressure plate support has an L-shaped pressure plate. The pressure plate support is connected to the vertical arm of the L-shaped pressure plate via a rotating shaft. A compression spring is also provided between the vertical arm of the L-shaped pressure plate and the pressure plate support. The horizontal arm of the L-shaped pressure plate can mate with the mounting hole on the upper surface of the frame mounting base. This invention solves the technical problems of complex structure and low efficiency in existing motor stator winding clamps. Although this clamp structure is relatively simplified and effectively solves the common problems of complex structure and low efficiency in traditional motor stator winding clamps, some shortcomings still exist in practical applications. During operation, the arc surface of the motor stator needs to be limited first, followed by vertical limitation. This step-by-step operation is cumbersome and cannot perform multi-directional, multi-point synchronous operation, thus limiting the overall work efficiency. Utility Model Content

[0004] In view of this, the present invention provides a clamp for winding motor stator, which can achieve multi-directional and multi-point synchronous constraint through the coordinated cooperation of positioning mechanism, limiting component and driving component, significantly improve work efficiency, and effectively solve the cumbersome operation problem caused by the traditional method of first limiting the arc surface of motor stator and then limiting its vertical direction.

[0005] To solve the above-mentioned technical problems, this utility model provides a clamp for winding a motor stator, including a stator mounting base and a positioning mechanism disposed on its upper end. The positioning mechanism includes a mounting cavity disposed on the upper end of the stator mounting base, and multiple rotating shafts are rotatably connected in the mounting cavity. Each rotating shaft has a limiting plate at its upper end. The upper end of the stator mounting base is also provided with a limiting component for limiting. This achieves multi-directional and multi-point synchronous constraint, significantly improves work efficiency, and effectively solves the cumbersome operation problem caused by the traditional method of first limiting the arc surface of the motor stator and then limiting its vertical direction.

[0006] The positioning mechanism also includes gears respectively set at the lower end of the rotating shaft. The inner arc surface of the outer diameter of the mounting cavity is rotatably connected to a toothed ring. Multiple gears are meshed with the toothed ring. The upper end of the stator mounting base is also provided with a drive assembly for driving the toothed ring to rotate, which serves the purpose of synchronous driving.

[0007] The drive assembly includes a connecting plate disposed on the outer arc surface of the tooth ring. An assembly cavity is provided at the upper end of the mounting cavity near the connecting plate. The assembly cavity is connected to the mounting cavity. The outer end of the connecting plate extends into the assembly cavity. A fixed seat is provided at one end of the assembly cavity. An electric push rod is rotatably connected in the fixed seat. The telescopic end of the electric push rod is rotatably connected to the opening of the connecting plate, thus playing a driving role.

[0008] The limiting assembly includes sliding grooves respectively set on the upper end of the inner arc surface of the stator mounting base near each limiting plate. Each sliding groove is slidably connected with a locking block, that is, a clamping force is applied synchronously to the outer arc surface of the stator.

[0009] The limiting assembly also includes push rods respectively set at the lower end of the limiting plate. The push rods are in movable contact with the adjacent limiting plates on the same side. The upper end of the stator mounting base is provided with a clearance groove near each push rod. The sliding groove is connected to the adjacent clearance groove on the same side. The clearance groove is configured to cooperate with the adjacent push rod on the same side, thus providing a driving source.

[0010] The clearance groove is arc-shaped, and the center of the circle containing the clearance groove coincides with the axis of the adjacent push rod on the same side. The movement trajectory of the push rod coincides with the circular trajectory of the adjacent clearance groove on the same side, thus ensuring the smooth movement of each mechanism.

[0011] The outer ends of the limiting plates are all inclined to ensure that they can move synchronously when sliding with the top rod.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. First, the stator mounting base is fixedly installed in the designated motor stator winding work area. Then, the relevant operators place the motor stator in the mounting base and then start the electric push rod. Its telescopic end pushes the connecting plate, causing the toothed ring to rotate in the mounting cavity. When the toothed ring rotates, it causes multiple rotating shafts and limiting plates to rotate synchronously through the gears meshing with it. This makes its inner end fit tightly against the upper end of the motor stator, thereby limiting the vertical direction of the motor stator. In conjunction with the limiting components, it achieves multi-directional and multi-point synchronous constraint, which significantly improves work efficiency and effectively solves the cumbersome operation problem caused by the traditional method of first limiting the arc surface of the motor stator and then limiting its vertical direction.

[0014] 2. The push rod follows the limit plate and rotates along the clearance groove, eventually contacting the locking block. Due to the inclined design of the inner end of the locking block, the locking block is pushed to slide in the slide groove, thereby applying a clamping force to the outer arc surface of the stator synchronously.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a clamp for winding the stator of a motor, such as... Figure 1-5 As shown: It includes a stator mounting base 100 and a positioning mechanism disposed on its upper end. The positioning mechanism includes a mounting cavity 200 disposed on the upper end of the stator mounting base 100. Multiple rotating shafts 201 are rotatably connected in the mounting cavity 200. The mounting cavity 200 is provided with a rotating hole that provides rotational support for each rotating shaft 201. The upper end of each rotating shaft 201 passes through the corresponding opening provided on the upper end of the stator mounting base 100 and extends to the outside. Each rotating shaft 201 is provided with a limiting plate 202 on its upper end. The upper end of the stator mounting base 100 is also provided with a limiting component for limiting.

[0023] First, the stator mounting base 100 is fixedly installed in the designated motor stator winding workplace. Then, the relevant operators place the motor stator in the mounting base 100. Subsequently, when the toothed ring 204 rotates, it causes multiple rotating shafts 201 and limiting plates 202 to rotate synchronously through the gear 203 that meshes with it. This causes the inner end of the toothed ring 204 to fit tightly against the upper end of the motor stator, thereby limiting the vertical direction of the motor stator. At the same time, the limiting components apply clamping force synchronously to the outer arc surface of the stator, realizing multi-directional and multi-point synchronous constraint, significantly improving work efficiency, and effectively solving the cumbersome operation problem caused by the traditional method of first limiting the arc surface of the motor stator and then limiting its vertical direction.

[0024] like Figure 2-4 As shown, the positioning mechanism also includes gears 203 respectively disposed at the lower end of the rotating shaft 201. All gears 203 are located within the mounting cavity 200. A toothed ring 204 is rotatably connected to the inner arc surface of the outer diameter of the mounting cavity 200. An annular groove is provided on the inner arc surface of the outer diameter of the mounting cavity 200 to provide rotational support for the toothed ring 204. Multiple gears 203 are meshed with the toothed ring 204. A drive assembly for driving the toothed ring 204 to rotate is also provided at the upper end of the stator mounting base 100. The drive assembly includes a connecting plate 300 disposed on the outer arc surface of the toothed ring 204. An assembly cavity 301 is provided at the upper end of the mounting cavity 200 near the connecting plate 300. The assembly cavity 301 is connected to the mounting cavity 200. The outer end of the connecting plate 300 extends into the assembly cavity 301. A fixing seat 302 is provided at one end of the assembly cavity 301. An electric push rod 303 is rotatably connected in the fixing seat 302. The telescopic end of the electric push rod 303 is rotatably connected to the opening of the connecting plate 300.

[0025] When the electric push rod 303 is activated, its telescopic end pushes the connecting plate 300, causing the toothed ring 204 to rotate within the mounting cavity 200. As the toothed ring 204 rotates, it causes multiple rotating shafts 201 and the limiting plate 202 to rotate synchronously through the gear 203 that meshes with it, thus achieving a synchronous driving effect.

[0026] like Figure 1-5As shown, the limiting assembly includes sliding grooves respectively disposed on the upper end of the inner arc surface of the stator mounting base 100 near each limiting plate 202. Each sliding groove is slidably connected with a locking block 400, which is a rubber locking block. The limiting assembly also includes push rods 401 respectively disposed on the lower end of the limiting plate 202. The push rods 401 respectively make movable contact with the adjacent limiting plate 202 on the same side. The upper end of the stator mounting base 100 near each push rod 401 is provided with a relief groove 402. The sliding grooves are respectively connected to the adjacent relief grooves 402 on the same side. The relief grooves 402 are respectively configured to cooperate with the adjacent push rods 401 on the same side. The relief grooves 402 are arc-shaped. The center of the circle where the relief groove 402 is located coincides with the axis of the adjacent push rod 401 on the same side. The movement trajectory of the push rod 401 coincides with the circular trajectory of the adjacent relief groove 402 on the same side. The outer ends of the limiting plates 202 are all inclined.

[0027] The push rod 401 rotates along the relief groove 402 following the limit plate 202 and eventually contacts the locking block 400. Due to the inclined design of the inner end of the locking block 400, the locking block 400 is pushed to slide in the slide groove, thereby applying a clamping force to the outer arc surface of the stator simultaneously to prevent it from rotating.

[0028] The working principle of the motor stator winding clamp provided by this utility model is as follows: First, the stator mounting base 100 is fixedly installed in the designated motor stator winding workplace. Then, the relevant operator places the motor stator in the mounting base 100. Subsequently, the electric push rod 303 is activated, and its telescopic end pushes the connecting plate 300, causing the toothed ring 204 to rotate in the mounting cavity 200. When the toothed ring 204 rotates, it causes multiple rotating shafts 201 and the limiting plate 202 to rotate synchronously through the gear 203 meshing with it, thereby making its inner end contact the motor. The upper end of the stator fits tightly, thus limiting the vertical direction of the motor stator. At the same time, the push rod 401 rotates along the relief groove 402 with the limiting plate 202 and eventually contacts the locking block 400. Due to the inclined design of the inner end of the locking block 400, the locking block 400 is pushed to slide in the slide groove, thereby applying clamping force to the outer arc surface of the stator synchronously. This achieves multi-directional and multi-point synchronous constraint, significantly improving work efficiency and effectively solving the cumbersome operation problem caused by the traditional method of first limiting the arc surface of the motor stator and then limiting its vertical direction.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
