Description

Technical Field

[0001] The utility model relates to the field of stator processing, in particular to a wire drawing adjustment device. Background Art

[0002] The stator consists of an outer ring and multiple frames arranged within it. The frames are evenly distributed along the inner circumference of the outer ring, and multiple coils are wound around the frames. The wire is a relatively hard metal wire, so the coils require a winding machine.

[0003] The wire pulling device is used to guide the wire at the discharge end of the wire discharging device so that the wire can be stretched straight and directed to the winding location. In order to avoid the winding device, the wire pulling device is generally set above or below the outer side of the stator outer ring. When the wire is extended to different frames of the stator, the following will occur: Figure 1 As shown in the figure, the wire is bent at different angles. The wire itself is a metal wire. When the wire is discharged, the bending part of the wire constantly rubs against the discharge port of the wire pulling device, causing the wire paint on the outer periphery of the wire to be worn. Utility Model Content

[0004] In order to reduce the wear between the wire and the discharge end of the wire pulling device, the utility model provides a wire pulling adjustment device.

[0005] The utility model provides a wire adjustment device adopting the following technical solutions:

[0006] A wire adjustment device, comprising:

[0007] The bracket is located near the outlet device;

[0008] The wire pulling part is used to guide the wire to the threading part;

[0009] A threading portion is provided at one end of the bracket, and the threading portion is provided with a threading hole for one end of the wire to pass through;

[0010] The driving member drives the threading part to rotate, and the discharge end of the threading part points to the direction of the stator frame.

[0011] The wire is passed through the threading part, guided to the threading part and passed out from the threading hole. During this period, the driving part is started to adjust the rotation angle of the threading part according to the connection angle between the frame and the threading part shaft. The rotation angle of the threading part can be quantitatively adjusted according to the different spacing and angles between the frame and the threading part, so that the friction between the wire and the threading part is reduced, which is beneficial to protecting the wire and making the wire outlet smoother.

[0012] Preferably, a force-applying portion is further provided at the end of the bracket, the threading portion is provided on the force-applying portion, the volume of the force-applying portion is larger than the threading portion, and the driving member is connected to the force-applying portion.

[0013] The volume of the threading part is generally small, and the threading part is arranged on the force applying part with large volume, so that the threading part is more easily driven to apply force, and the threading part also needs a rotating support point. After the force applying part is arranged, the rotating support point can be arranged on the force applying part, so as to reduce the damage caused by the too complex structure of the threading part, and to make the movement of the whole device more stable.

[0014] Preferably, the pulling wire part comprises a first wire wheel and a second wire wheel arranged at two ends of the support respectively, the second wire wheel is arranged at one end of the support where the threading part is arranged, and the first wire wheel and the second wire wheel are both rotationally connected to the support, and the first wire wheel and the second wire wheel are both spaced from the side wall of the support.

[0015] The wire is passed through the space between the first wire wheel and the side wall of the support, so that one end of the wire is embedded in the peripheral wall of the first wire wheel, and then the wire is extended to the second wire wheel, so that the wire slot is wound to the side of the second wire wheel away from the support, and then the wire is passed into the threading hole, so as to pull the wire away from the side wall of the support, preventing the wire from directly adhering to the side wall of the support and extending to the threading hole, so as to prevent the wire from sliding and rubbing with the side wall of the support and causing wear.

[0016] Preferably, the peripheral wall of the first wire wheel and the second wire wheel is provided with an annular wire slot, and the wire is embedded in the wire slot.

[0017] The wire embedded in the wire slot makes the wire not easy to separate from the wire wheel, so that the wire stably extends in the pulling wire part.

[0018] Preferably, the end of the support is provided with a mounting groove, the rotating shaft of the second wire wheel is rotationally connected to the side walls of the mounting groove on both sides, and the side wall of the force applying part is provided with an extension plate, and the extension plate is rotationally connected to the rotating shaft of the second wire wheel.

[0019] The force applying part and the second wire wheel share the rotating shaft, so that the mutual avoidance of the second wire wheel and the force applying part is more easily arranged, and the space in the mounting groove can be fully utilized. If the second wire wheel and the force applying part do not share the rotating shaft, the rotating shaft of the force applying part needs to avoid the whole second wire wheel to be arranged, which causes the end of the support to be complex in structure and large in volume.

[0020] Preferably, the driving member comprises a gas cylinder and a driving rod, the gas cylinder is arranged at one end of the support away from the threading part, the driving end of the gas cylinder is rotationally connected to one end of the driving rod, and the other end of the driving rod is rotationally connected to the force applying part; the threading part comprises a threading nozzle, and the threading nozzle is arranged at one end of the force applying part away from the extension plate.

[0021] The gas cylinder is started, so that the driving end of the gas cylinder drives the end of the driving rod to move towards the direction close to or away from the gas cylinder, the force applying part is difficult to slide downward due to the limitation of the rotating shaft of the extension plate, so that the force applying part rotates, and the direction of the threading nozzle arranged on one side of the force applying part changes.

[0022] Preferably, a side wall of the bracket is provided with an avoidance groove for the movement of the driving rod, and the driving rod is partially located in the avoidance groove.

[0023] On the one hand, the avoidance groove can accommodate the driving rod and reduce the space occupied by the exposed driving rod. On the other hand, the avoidance groove can reduce the weight and material of the bracket.

[0024] Preferably, the threading hole passes through the force-applying portion, and the hole wall of the threading hole and the side wall of the force-applying portion transition into an arc surface.

[0025] If the hole wall of the threading hole and the side wall of the force-applying portion are at right angles, the sharp corners will easily wear the wire, so the arc surface setting is beneficial to protecting the wire.

[0026] In summary, the present invention has the following beneficial technical effects:

[0027] The wire is passed through the threading part, guided to the threading part and passed out from the threading hole. During this period, the driving part is started to adjust the rotation angle of the threading part according to the connection angle between the frame and the threading part shaft. The rotation angle of the threading part can be quantitatively adjusted according to the different spacing and angles between the frame and the threading part, so that the friction between the wire and the threading part is reduced, which is beneficial to protecting the wire and making the wire outlet smoother.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 2-5 The utility model is described in further detail.

[0035] The embodiment of the utility model discloses a wire adjustment device.

[0036] Reference Figure 2 as well as Figure 3 , a wire adjustment device, comprising:

[0037] Bracket 1, located near the outlet device;

[0038] The wire pulling portion is used to guide the wire 2 to the threading portion;

[0039] The threading part is provided at one end of the bracket 1 and has a threading hole 3 for one end of the wire 2 to pass through;

[0040] The driving member drives the threading part to rotate, and the discharge end of the threading part points to the direction of the stator frame.

[0041] The wire 2 is passed through the threading part, guided to the threading part and passed out from the threading hole 3. During this period, the driving part is started, and the rotation angle of the threading part is adjusted according to the connection angle between the skeleton and the threading part shaft 10. The rotation angle of the threading part can be quantitatively adjusted according to the different spacing and angles between the skeleton and the threading part, so that the friction between the wire 2 and the threading part is reduced, which is beneficial to protecting the wire 2 and making the wire 2 come out more smoothly.

[0042] Reference Figure 2 as well as Figure 4 In this embodiment, a force-applying portion 4 is further provided at the end of the bracket 1 , the threading portion is provided on the force-applying portion 4 , the volume of the force-applying portion 4 is larger than the threading portion, and the driving member is connected to the force-applying portion 4 .

[0043] The volume of the threading part is generally small. Setting it on the larger force-applying part 4 makes it easier to drive the threading part to apply force. The threading part also needs to rotate the support point. After the force-applying part 4 is set, the support point can be set on the force-applying part 4, reducing the situation where the threading part structure is too complicated and easy to be damaged, making the movement of the entire device more stable.

[0044] Reference Figure 4 as well as Figure 5 In this embodiment, the wire pulling part includes a first wire wheel 5 and a second wire wheel 6 respectively provided at both ends of the bracket 1. The second wire wheel 6 is located at the end of the bracket 1 where the threading part is provided. The first wire wheel 5 and the second wire wheel 6 are both rotatably connected to the bracket 1, and there is a distance between the first wire wheel 5 and the second wire wheel 6 and the side wall of the bracket 1.

[0045] Pass the wire 2 between the first wire wheel 5 and the side wall of the bracket 1, so that one end of the wire 2 is embedded in the peripheral wall of the first wire wheel 5, and then extend the wire 2 to the second wire wheel 6, so that the wire groove 7 is wrapped around the side of the second wire wheel 6 away from the bracket 1, and then pass the wire 2 into the threading hole 3, so as to pull the wire 2 away from the side wall of the bracket 1, and prevent the wire 2 from directly adhering to the side wall of the bracket 1 and extending to the threading hole 3, which may cause sliding friction between the wire 2 and the side wall of the bracket 1 and thus cause wear.

[0046] Reference Figure 3 as well as Figure 5 In this embodiment, the peripheral walls of the first wire wheel 5 and the second wire wheel 6 are both provided with an annular wire groove 7, and the wire 2 is embedded in the wire groove 7.

[0047] The wire 2 is embedded in the wire groove 7 so that the wire 2 is not easily separated from the wire wheel, and the wire 2 is stably extended in the wire pulling part.

[0048] Reference Figure 3 as well as Figure 5 In this embodiment, a mounting groove 8 is opened at the end of the bracket 1, and the rotating shaft 10 of the second wire wheel 6 is rotatably connected to the side walls of the mounting groove 8. The side wall of the force-applying part 4 is provided with an extension plate 9, which is rotatably connected to the rotating shaft 10 of the second wire wheel 6.

[0049] The force-applying part 4 and the second wire wheel 6 share the rotating shaft 10, which makes it easier to set the mutual avoidance between the second wire wheel 6 and the force-applying part 4, and can fully utilize the space in the installation groove 8. If the second wire wheel 6 and the force-applying part 4 do not share the rotating shaft, the rotating shaft of the force-applying part 4 needs to avoid the second wire wheel 6 as a whole, resulting in a complicated end structure of the bracket 1 and an increased volume.

[0050] Reference Figure 2 as well as Figure 4 In this embodiment, the driving member includes a cylinder 11 and a driving rod 12. The cylinder 11 is arranged at the end of the bracket 1 away from the threading part. The driving end of the cylinder 11 is rotatably connected to one end of the driving rod 12, and the other end of the driving rod 12 is rotatably connected to the force-applying part 4; the threading part includes a threading nozzle 13, and the threading nozzle 13 is arranged at the end of the force-applying part 4 away from the extension plate 9.

[0051] The cylinder 11 is started, so that the driving end of the cylinder 11 drives the end of the driving rod 12 to move toward and away from the cylinder 11. The force-applying part 4 is restricted by the rotating shaft 10 of the extension plate 9 and is difficult to slide down, thereby causing the force-applying part 4 to rotate, thereby changing the direction of the threading nozzle 13 provided on one side of the force-applying part 4.

[0052] Reference Figure 2 as well as Figure 4 In this embodiment, a side wall of the bracket 1 is provided with an avoidance groove 14 for the driving rod 12 to move, and the driving rod 12 is partially located in the avoidance groove 14.

[0053] On one hand, the avoidance groove 14 can accommodate the driving rod 12 and reduce the space occupied by the driving rod 12 . On the other hand, the avoidance groove 14 can reduce the weight and material of the bracket 1 .

[0054] Reference Figure 3 as well as Figure 5 In this embodiment, the threading hole 3 passes through the force-applying portion 4, and the hole wall of the threading hole 3 and the side wall of the force-applying portion 4 are in an arc transition to form an arc surface.

[0055] If the hole wall of the threading hole 3 and the side wall of the force-applying portion 4 form a right angle, the sharp corner will easily wear the wire 2 , so the arc surface is helpful to protect the wire 2 .

[0056] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
