Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically to a wire feeding device for a stator winding machine. Background Technology

[0002] A stator winding machine is a specialized piece of equipment used for manufacturing stator windings for motors. It is mainly used to wind enameled wire and other conductors onto the stator core according to specific rules and requirements to form the stator winding of the motor. It usually consists of a wire spool frame, a tension controller, etc., which are used to place the wire spool and control the tension of the conductor during the unwinding process to ensure that the conductor can be unwound evenly and stably, providing good starting conditions for subsequent winding operations.

[0003] Existing wire feeding devices may require complex mechanical structures or additional tools to perform the winding and feeding actions, resulting in cumbersome operation, increased workload for operators, and reduced production efficiency. On the other hand, the stability of the winding is difficult to guarantee during the winding process. When the winding speed changes or is affected by external interference, the winding is prone to loosening, deviation, or tangling, affecting the quality of the stator winding, which may lead to a decrease in motor performance or even failure. In addition, some devices are difficult to reliably fix the take-up drum when needed, which can easily lead to accidental rotation. Moreover, there is a lack of precise and effective means to adjust the tension of the winding. Therefore, this application proposes another technical solution to address the above problems. Utility Model Content

This device offers advantages such as convenient and rapid winding and unwinding, as well as tensioning and winding. It solves the problems of cumbersome winding operations, increased operator workload, and reduced production efficiency associated with existing methods. Furthermore, during the winding process, the stability of the winding is difficult to guarantee. When the winding speed changes or is subject to external interference, the winding is prone to loosening, shifting, or becoming tangled, affecting the quality of the stator winding and potentially leading to decreased motor performance or even malfunction. In addition, some devices cannot reliably fix the winding drum when needed, easily leading to accidental rotation.

[0011] Furthermore, the limiting ring has a groove inside, and the winding body is slidably connected to the limiting ring through the groove.

[0012] Furthermore, the pull ring is semi-circular, and the pull ring is slidably connected to the winding body.

[0013] Furthermore, a rubber sleeve is provided on the outer side of the rocker arm, and a handle bracket is fixedly installed on the top of the support base.

[0021] 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.

[0022] Please see Figures 1 to 4 The stator winding machine in this embodiment has a wire feeding device, which includes a movable wheel 1 and a winding feeding mechanism is provided on the top of the movable wheel 1.

[0023] In Embodiment 1, the winding mechanism includes a support base 2 fixedly mounted on the top of the movable wheel 1. Two support plates 3 are fixedly mounted on the top of the support base 2. The support base 2 has a bearing groove inside. The rotating shaft 4 is rotatably connected to the support plate 3 through the bearing groove, which helps the rotating shaft 4 to rotate inside the support plate 3. The rotating shaft 4 is rotatably connected inside the support plate 3. A rocker arm 5 is fixedly mounted on the right side of the rotating shaft 4, and a turntable 6 is fixedly mounted on the left side of the rotating shaft 4.

[0024] The turntable 6 has a pin 7 inserted inside, which is connected to the support plate 3. The turntable 6 has a ring of slots inside, and the left side of the support plate 3 has a corresponding slot. The pin 7 is inserted into the turntable 6 and the support plate 3 through the slots, which helps to fix the turntable 6. A winding drum 8 is fixedly installed on the outside of the rotating shaft 4. A limit plate 9 is fixedly installed on the outside of the winding drum 8. A winding body 10 is movably connected to the outside of the winding drum 8.

[0025] In embodiment 2, an auxiliary component is provided on the front of the support base 2. The auxiliary component includes three limiting rings 11 fixedly installed on the front of the support base 2. The limiting rings 11 have wire grooves inside. The winding body 10 is slidably connected to the limiting rings 11 through the wire grooves, which helps to limit the winding body 10. An electric push rod 12 is fixedly installed on the top of the support base 2.

[0026] The output shaft of the electric actuator 12 is fixedly equipped with a pull ring 13. The pull ring 13 is semi-circular and is slidably connected to the winding body 10, which helps the pull ring 13 to pull and tighten the winding body 10. The outside of the rocker arm 5 is equipped with a rubber sleeve for easy gripping and rotation. The top of the support base 2 is fixedly equipped with a handle 14 for easy pulling of the entire device.

[0027] It should be noted that the unwinding device of this stator winding machine is flexible in its operation. By rotating the rocker arm 5, the winding body 10 can be easily wound and unwound, making it easy to operate and efficient in conjunction with the stator winding machine. The pin 7 can be used to connect and fix the turntable 6 to the support plate 3, thereby stabilizing the rotating shaft 4 and the winding drum 8, preventing accidental rotation, and ensuring the stability of the winding process. The electric push rod 12 and the pull ring 13 work together to tighten the winding body 10 as needed, and the three limit rings 11 provide guidance and limit to ensure the stability of the winding body 10 when tightened, avoiding deviation and tangling. With the coordinated work of multiple components, this device meets the diverse unwinding needs of the stator winding machine and improves the efficiency and quality of the winding work.

[0028] The working principle of the above embodiments is as follows:

[0029] When the stator winding machine's unwinding device needs to wind the winding body 10, the rocker arm 5 is turned, which drives the rotating shaft 4 to rotate. The take-up drum 8 on the outside of the rotating shaft 4 rotates accordingly, thereby winding the winding body 10 onto the take-up drum 8. The limiting plate 9 can prevent the winding body 10 from slipping off the sides of the take-up drum 8 during the winding process. When unwinding, the rocker arm 5 is turned in the opposite direction, causing the take-up drum 8 to reverse and release the winding body 10. If it is necessary to fix the position of the take-up drum 8, the pin 7 can be inserted into the corresponding slots of the turntable 6 and the support plate 3 to achieve the insertion and fixation of the turntable 6 and the support plate 3, thereby fixing the rotating shaft 4 and the take-up drum 8 and preventing them from rotating accidentally when they are not needed. The auxiliary components on the front of the bearing seat 2 are used to tighten the winding body 10.

[0030] When it is necessary to tighten the winding body 10, the electric push rod 12 is activated. The output shaft of the electric push rod 12 extends and drives the pull ring 13 to move. The pull ring 13 is slidably connected to the winding body 10, thereby pulling the winding body 10 to tighten it. The three limit rings 11 provide guidance and limit for the winding body 10, ensuring that the winding body 10 remains stable during the tightening process and does not experience significant deviation or tangling. During the entire winding, unwinding and tightening process, the various components of the device work together to meet the unwinding requirements of the stator winding machine.
