Description

Technical Field

[0001] The present invention relates to the field of motors, and particularly to a motor stator winding device. Background Art

[0002] Motors are essential power devices in industrial production. Among them, electromagnetic DC motors mainly consist of a stator, a rotor, a commutator, brushes, and a housing. Since the motor is one of the main power sources of the device, regular maintenance work needs to be carried out on the motor. When the winding group on the outer side of the stator is being repaired, it may need to be replaced to ensure the normal operation of the motor. However, the replacement environment at this time is not suitable for placing on a winding machine for rewinding.

[0003] However, when the staff repairs the stator and the winding group on the outer side of the stator, they often need to rewind the outer side of the stator. However, the working environment of the existing winding machines is not convenient for the staff to rewind, and the working space is greatly restricted. Therefore, a motor stator winding device is proposed for the above problems. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art. In order to make up for the deficiencies in the prior art, the working environment of the existing winding machines is not convenient for the staff to rewind, and the working space is greatly restricted. The present invention proposes a motor stator winding device.

[0005] A motor stator winding device includes a housing. A fixing frame is installed at the bottom end inside the housing. A bearing is installed on the top of the fixing frame. External threads are provided on the inner surface of the housing. A bottom channel is provided at the bottom of the inner surface of the housing, and the bottom channel is fixedly communicated with the external threads. The top of the fixing frame is fixedly provided with a base through the bearing. Mounting members are welded on the outer surface of the base. Rollers are installed inside the mounting members through shaft rods. The positions of the rollers correspond to the positions of the bottom channels. A cylinder is welded on the top of the base. A middle through hole is provided on the inner bottom surface of the bottom channel. Through the friction between the rollers and the wire, the wire can smoothly pass through the middle through hole and the tail through hole in the conical block to smoothly discharge the wire. The staff can fix the top end of the wire to the stator, and then continuously discharge the wire through a device with a smaller diameter, and through the winding of the staff, smoothly rewind the wire on the outer side of the stator, bringing convenience to the maintenance work of the staff.

[0006] Preferably, internal threads are provided on the outer surface of the cylinder, and the diameter of the internal threads is the same as the diameter of the external threads. The same internal and external threads can enable the wire to smoothly move inside the device.

[0007] Preferably, a conical block is welded to the bottom end of the housing, and the inner diameter of the conical block shows a gradually decreasing trend. The tip of the conical block can better guide the direction of the control wire.

[0008] Preferably, a plurality of anti-slip stickers are equidistantly fixed on the outer surface of the housing, and the direction of the anti-slip stickers is perpendicular to the rotation direction of the device. The perpendicular anti-slip stickers can increase the friction between the device and the staff.

[0009] Preferably, a top cover is fitted into the top of the housing. An installation hole is opened at the center of the top of the top cover. The top cover can protect the space inside the housing from entering sundries and affecting the operation of the device.

[0010] Preferably, a fixing seat is welded to the top of the column body, and the top end of the fixing seat penetrates through the inside of the installation hole and extends to the outside of the top cover. The fixing seat is not connected to the top cover, which allows the triangular handle to smoothly drive the column body to move.

[0011] Preferably, a connecting block is fixed to the top end of the fixing seat, and a triangular handle is welded to the top end of the connecting block. The triangular handle fixed by the connecting block can smoothly drive the column body to move.

[0012] Preferably, a top through hole is opened on the top of the top cover, and the top through hole is fixedly communicated with the inside of the housing. By inserting the wire smoothly through the top through hole between the internal thread and the external thread, the working time for the staff to fix the wire inside the device can be saved.

[0013] Preferably, a tail through hole is opened inside the conical block, and the tail through hole is fixedly communicated with the middle through hole. The communicated tail through hole and middle through hole can facilitate the wire to be smoothly discharged for winding work.

[0014] Preferably, rounded corners are provided at two corners of the triangular handle, and an opening is provided at the cross bar of the triangular handle. The triangular handle with rounded corners can improve the comfort level of the staff during use.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, by threading the wire between the internal thread and the external thread until it reaches the bottom channel, at this time, the staff can rotate the column body, so that the column body can drive the bottom base to rotate. At this time, the rollers installed on the outer surface of the base can rotate the wire located in the bottom channel. Through the friction between the rollers and the wire, the wire can be smoothly discharged through the middle through hole and the tail through hole in the conical block. The staff can fix the top end of the wire to the stator, and then continuously discharge the wire through the device with a smaller diameter, and through the winding of the staff, the wire outside the stator can be successfully rewound, which brings convenience to the maintenance work of the staff;

[0017] 2. The present invention can smoothly insert a wire between the internal thread and the external thread through the top through hole, which can save the working time of the staff in fixing the wire inside the device. Moreover, the top of the cylinder is connected with a triangular handle through a fixing seat, which can provide a large force application area for the staff with less material consumption, making it more convenient for the staff to use the device. In addition, the base and the fixing frame are connected together through a bearing, which can ensure that the device can continuously extrude the wire located in the bottom channel.

[0030] Embodiment 1

[0031] Please refer to Figures 1-6As shown in the figure, a winding device for a motor stator. The invented winding device for a motor stator includes a housing 1. At the bottom end inside the housing 1, a fixing frame 19 is installed. At the top of the fixing frame 19, a bearing 20 is installed. On the inner surface of the housing 1, an external thread 13 is provided. At the bottom of the inner surface of the housing 1, a bottom channel 14 is provided, and the bottom channel 14 is fixedly communicated with the external thread 13. At the top of the fixing frame 19, a base 18 is fixed through the bearing 20. On the outer surface of the base 18, a mounting member 17 is welded. Inside the mounting member 17, a roller 16 is installed through a shaft rod. The position of the roller 16 corresponds to the position of the bottom channel 14. At the top of the base 18, a cylinder 9 is welded. At the inner bottom surface of the bottom channel 14, a middle through hole 15 is provided. During operation, the staff can rotate the cylinder 9, so that the cylinder 9 can drive the base 18 at the bottom to rotate. At this time, the roller 16 installed on the outer surface of the base 18 can rotate the wire located in the bottom channel 14. Through the friction between the roller 16 and the wire, the wire can smoothly pass through the middle through hole 15 and the tail through hole 4 in the tapered block 3 to discharge the wire smoothly. The staff can fix the top end of the wire to the stator, and then continuously discharge the wire through a device with a smaller diameter. Through the winding of the staff, the wire outside the stator can be rewound smoothly, which brings convenience to the maintenance work of the staff.

[0032] On the outer surface of the cylinder 9, an internal thread 10 is provided, and the diameter of the internal thread 10 is the same as the diameter of the external thread 13. During operation, the internal thread 10 and the external thread 13 can always be used to fix the wire's path, so that the wire can be discharged from the device smoothly.

[0033] At the bottom end of the housing 1, a tapered block 3 is welded, and the inner diameter of the tapered block 3 shows a gradually decreasing trend. During operation, the tip of the tapered block 3 can better control the path of the control wire.

[0034] On the outer surface of the housing 1, a plurality of anti-slip stickers 2 are fixedly arranged at equal intervals, and the direction of the anti-slip stickers 2 is perpendicular to the rotation direction of the device. During operation, the perpendicular anti-slip stickers 2 can be perpendicular to the force application direction of the staff, improving the staff's control over the device.

[0035] At the top of the housing 1, a top cover 6 is fitted. At the center of the top of the top cover 6, a mounting hole 11 is provided. During operation, the top cover 6 can protect the space inside the housing 1 from entering sundries and affecting the device's operation. And the staff can also clean the space inside the device by opening the top cover 6.

[0036] At the top of the cylinder 9, a fixing seat 8 is welded, and the top end of the fixing seat 8 penetrates through the inside of the mounting hole 11 and extends to the outside of the top cover 6. During operation, by making the fixing seat 8 not connected to the top cover 6 through the mounting hole 11, when the triangular handle 5 drives the cylinder 9 to move smoothly, it will not be affected by the friction of the top cover 6.

[0037] A connecting block 7 is fixed to the top end of the fixed seat 8, and a triangular handle 5 is welded to the top end of the connecting block 7. During operation, the triangular handle 5 fixed by the connecting block 7 can smoothly drive the cylinder 9 to move, so that the roller 16 can smoothly discharge the wire and complete the winding work.

[0038] A top through hole 12 is formed in the top of the top cover 6, and the top through hole 12 is fixedly communicated with the inside of the housing 1. During operation, the wire is smoothly inserted between the internal thread 10 and the external thread 13 through the top through hole 12, so that the wire can smoothly reach the inside of the bottom channel 14, which can save the working time of the staff to fix the wire inside the device.

[0039] A tail through hole 4 is formed in the conical block 3, and the tail through hole 4 is fixedly communicated with the middle through hole 15. During operation, the communicated tail through hole 4 and the middle through hole 15 are used to smoothly insert the wire inside the device, and when the roller 16 rotates, it is convenient for the wire to be smoothly discharged for winding work.

[0040] Rounded corners are provided at two corners of the triangular handle 5, and an opening is provided at the cross bar of the triangular handle 5. During operation, the triangular handle 5 with rounded corners can improve the comfort of the staff when using it.

[0041] Embodiment 2

[0042] Please refer to Figure 7 As shown, compared with Embodiment 1, as another implementation manner of the present invention, a threaded member 21 is fixed to the bottom end of the triangular handle 5; during operation, the staff can remove the triangular handle 5 through the threaded member 21, which is convenient for the staff to store.

[0043] Working principle: By rotating the triangular handle 5, the triangular handle 5 drives the bottom base 18 to rotate by driving the cylinder 9. At this time, the roller 16 installed on the outer surface of the base 18 can rotate the wire located in the bottom channel 14. Through the friction between the roller 16 and the wire, the wire can smoothly pass through the middle through hole 15 and the tail through hole 4 in the conical block 3 to smoothly discharge the wire. The staff can fix the top end of the wire to the stator, and then continuously discharge the wire through a device with a smaller diameter, and through the winding of the staff, the wire outside the stator can be smoothly rewound.

[0044] Compared with the prior art, in the present invention, a wire is threaded between an internal thread and an external thread until it reaches the bottom channel. At this time, a worker can rotate the cylinder, and the cylinder can drive the base at the bottom to rotate. At this time, the rollers installed on the outer surface of the base can rotate the wire located in the bottom channel. Due to the frictional force between the rollers and the wire, the wire can smoothly pass through the middle through-hole and the tail through-hole in the tapered block to smoothly discharge the wire. The worker can fix the top end of the wire to the stator, and then continuously discharge the wire through a device with a smaller diameter. Through the winding of the worker, the wire outside the stator can be successfully rewound, bringing convenience to the maintenance work of the worker;

[0045] The wire can be smoothly inserted between the internal thread and the external thread through the top through-hole, which can save the working time of the worker to fix the wire inside the device. Moreover, the top end of the cylinder is connected to a triangular handle through a fixing seat, which can provide a larger force application area for the worker with less material consumption, making it more convenient for the worker to use the device. And the base and the fixing frame are connected together through a bearing, which can ensure that the device can continuously extrude the wire located in the bottom channel.

[0046] The above embodiments only represent several implementation modes of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
