Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to a feeding device for stator coil production. Background Technology

[0002] The stator of a new energy vehicle motor is the stationary part of the motor and plays an important role in the motor's operation. In order to meet the requirements of new energy vehicles for driving range and power performance, the design and manufacturing of motor stators are increasingly focused on improving power density. This requires the use of more advanced materials, optimized structural design and manufacturing processes to achieve higher power output within a limited space. The stator coil is usually made of copper wire, and the windings are arranged on the stator core in a specific pattern. In order to reduce energy loss and improve efficiency, the stator coil generally uses high-quality insulated copper wire.

[0003] During stator coil production, multiple coil discs need to be placed and supported by a feeding rack to facilitate subsequent processing of copper wire. Since one end of the support shaft for placing the coil discs is usually suspended, when the coil discs are placed on the surface of the support shaft, the support shaft will tilt and shake due to uneven force. Therefore, we propose a feeding device for stator coil production to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for stator coil production, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A feeding device for stator coil production includes a base, a guide frame fixed to the top of the base, two sets of support seats installed on the guide frame, and a rotating rod rotatably connected to each support seat via bearings. Two lead screws are rotatably connected between the inner walls of the two sides of the base via bearings. A bracket for auxiliary support of the rotating rod is slidably connected to the surface of the two lead screws. Bearing seats are installed inside the through holes opened in the side walls of the brackets, and a rotatable limiting component fixed to the bracket is provided on one side of each bearing seat.

[0009] Furthermore, the rotatable limiting component includes an annular rail fixed at the through hole of the bracket, a rotating ring rotatably connected inside the rotating groove of the annular rail, a limiting ring fixed to one side wall of the rotating ring, and a rubber buffer pad fixed to one side wall of the limiting ring.

[0010] Furthermore, two guide frames are fixed to the top of the base, and two guide rods adapted to the bracket are fixed between the two guide frames, and the bracket slides on the surface of the two guide rods.

[0011] Furthermore, each lead screw has a sprocket fixed to its surface, and the two sprockets are connected by a chain drive.

[0012] Furthermore, two telescopic covers for protecting the lead screw are fixed to one side wall of the bracket, and the other end of each telescopic cover is fixedly connected to the inner wall of one side of the base.

[0013] Furthermore, the top of the base is provided with two slots for making way for the support.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a feeding device for stator coil production, which has the following advantages:

[0016] This utility model features a support bracket on one side of the guide frame. When the coil disc is placed on the surface of the rotating rod, the bracket can be moved to provide auxiliary support to the suspended end of the rotating rod. This prevents the rotating rod from tilting or wobbling due to uneven force after the coil disc is placed on it, ensuring that the coil disc is in a horizontal and stable state. Furthermore, when the support bracket supports the rotating rod, the rotatable limiting component can limit and fix the coil disc without affecting its rotation, eliminating the need for additional fixing structures.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention discloses a feeding device for stator coil production, including a base 1, a guide frame 2 fixed on the top of the base 1, two sets of support seats 3 installed on the guide frame 2, and a rotating rod 4 rotatably connected to each support seat 3 via bearings. Two lead screws 5 are rotatably connected between the inner walls of the two sides of the base 1 via bearings. Two telescopic covers 13 for protecting the lead screws 5 are fixed to one side wall of a bracket 6, and the other end of each telescopic cover 13 is fixedly connected to one side wall of the base 1, which can protect the lead screws 5 and prevent them from being affected by dust and other impurities during use, thereby extending their service life. The surfaces of the two lead screws 5 are slidably connected to a bracket 6 for auxiliary support of the rotating rod 4. The top of the base 1 has two slots 14 for making way for the brackets 6, which can make way and prevent the brackets 6 from being interfered with when sliding on the base 1. Bearing seats 7 are installed inside the through holes opened on the side wall of the bracket 6. Each side of the support 7 is provided with a rotatable limiting piece 8 fixed on the bracket 6. During the feeding device used for stator coil production, after placing it in a suitable position, the copper coils can be placed on the surface of the rotating rod 4. The motor is started to drive the lead screw 5 to rotate. After the lead screw 5 rotates, it will drive the bracket 6 to move closer to the guide frame 2. After it moves, the bearing seats 7 inside the through holes of the bracket 6 will be sleeved on the surface of the rotating rod 4. At this time, it can support the suspended end of the rotating rod 4, preventing the surface of the rotating rod 4 from tilting or shaking after the coil is placed, so that it will be more stable during rotation. When the bracket 6 moves, it will simultaneously drive the rotatable limiting piece 8 to move and fit with one side of the coil. At this time, the coil can be limited, thus preventing the coil from rotating on its own after being installed on the surface of the rotating rod 4. When the coil needs to be replaced later, the motor is started to drive the lead screw 5 to reverse, and the bracket 6 can be moved away from the guide frame 2.

[0025] like Figure 4As shown, in some embodiments, the rotatable limiting member 8 includes an annular rail 801 fixed at the through hole of the bracket 6. A rotating ring 802 is rotatably connected inside the rotating groove of the annular rail 801. A limiting ring 803 is fixed to one side wall of the rotating ring 802, and a rubber buffer pad 804 is fixed to one side wall of the limiting ring 803. In use, the moving limiting ring 803 will fit tightly against the side of the rotating rod 4 where the coil disk is placed, thus limiting the coil disk. The anti-slip rubber buffer pad 804 is provided on one side of the limiting ring 803, which can play a buffering role. At the same time, it can make the limiting ring 803 more stable after fixing the coil disk. Furthermore, with the cooperation of the annular rail 801 and the rotating ring 802, the limiting ring 803 rotates on the bracket 6. Therefore, when the motor drives the coil disk to rotate through the rotating rod 4, it will not be interfered with.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, two guide frames 9 are fixed to the top of the base 1, and two guide rods 10 adapted to the bracket 6 are fixed between the two guide frames 9. The bracket 6 slides on the surface of the two guide rods 10. The guide rods 10 can play an auxiliary guiding role for the bracket 6, so that the bracket 6 will be more stable during movement.

[0027] like Figure 2 As shown, in some embodiments, sprockets 11 are fixed on the surface of the lead screw 5. The two sprockets 11 are connected by a chain 12, so that the two lead screws 5 can be driven to rotate synchronously under the action of a motor, so as to save production costs.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
