Abstract
Description
Technical Field
[0001] The utility model relates to the field of stator processing, in particular to a stator winding machine wire protection sleeve mechanism used for matching the stator. 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 winding machine includes a clamp for clamping the stator, a feeding device for feeding wire and a winding device. A clamping piece is also provided around the clamp to clamp one end of the wire to assist the winding device in winding.
[0004] When winding the wire, after a copper wire is wound around the first frame, it needs to be wound around the third, fourth or fifth frame. In other words, adjacent frames cannot be wound around the same copper wire. However, if the copper wire jumps over the adjacent frames, it is easy for the copper wire to abut against the coil on the adjacent frame, causing a short circuit. Therefore, the copper wire needs to be wound around the outer ring of the outer ring, and then bent so that the copper wire sticks to the outer wall of the outer ring and extends to the next frame to be wound. It is then bent again so that the copper wire is bent back into the stator and wound again. The ends of the coils on the two adjacent frames are separated by the insulation properties of the outer ring.
[0005] The applicant believes that the projection of the coils wound by adjacent frames on the bottom of the stator has the following Figure 1 In the overlapping situation shown, if the multiple copper wires attached to the outer ring come into contact with each other, multiple coils will be conductive, affecting the quality of the assembled stator. Utility Model Content
[0006] In order to reduce the situation where multiple copper wires of the stator outer ring are entangled or overlapped and abutted, the utility model provides a stator winding machine wire protection sleeve mechanism for cooperating with the stator.
[0007] The utility model provides a stator winding machine wire protection sleeve mechanism for cooperating with the stator, which adopts the following technical solutions:
[0008] A stator winding machine wire sheath mechanism for cooperating with a stator is provided below a fixture that clamps the stator, and the fixture is rotatable relative to the wire sheath mechanism. The invention is characterized in that it comprises a wire sheath and a driving member, wherein the wire sheath is annular, and the driving member drives the wire sheath to approach the stator and sheath around the outer periphery of the stator. When the wire sheath is sheathed around the outer periphery of the stator, the top wall of the wire sheath abuts against the copper wire on the outer periphery of the stator outer ring.
[0009] During stator processing, after the copper wire is wound on one frame, the wire hooking device will hook the copper wire out of the stator, and at the same time, the clamp will be rotated so that the next frame that needs to be wound is rotated to a position opposite to the wire hooking device. Then the wire hooking assembly will wind the copper wire back into the stator. At this time, the copper wire between the two frames will be wound onto the outer wall of the outer ring, and then the wire hooking device will retreat to complete the winding action on the outer periphery of the outer ring. At this time, the wire guard mechanism is started, so that the wire guard moves upward toward the direction close to the stator until the wire guard is connected to the outer periphery of the stator. During the upward movement of the wire guard, the top wall of the wire guard abuts against the copper wire on the outer periphery of the stator, thereby pushing the copper wire upward. The driving part drives the wire guard to slide up a certain stroke. For the same copper wire, the upward sliding stroke of the wire guard is the same; for different copper wires, the upward sliding stroke of the wire guard is different. The different upward sliding strokes make there be height differences between multiple copper wires to avoid mutual abutment and conduction, which is beneficial to improve the stability of the copper wire and the stator after winding assembly.
[0010] Preferably, the distance between the copper wire first wound on the stator and the end of the stator close to the wire sheath is the largest, the distance between the copper wire last wound on the stator and the end of the stator close to the wire sheath is the smallest, and the distances between the intermediate copper wires and the stator end decrease step by step in the order of winding.
[0011] By successively lowering the height of the copper wires on the outer periphery of the outer ring, the overlapping parts of adjacent copper wires are prevented from rubbing against or entangled with each other when being pushed up, so that multiple copper wires can be raised in an orderly manner and the situation of abutting and conducting is avoided.
[0012] Preferably, the stator matched with the wire protection sleeve mechanism includes an outer ring and multiple frames, the bottom wall of the outer ring is provided with multiple groups of notches, the notches correspond to multiple frames, the notches of the multiple frames wound in the same copper wire belong to the same group, and the depths of the multiple groups of notches are different.
[0013] After winding the wire on each frame, one end of the copper wire needs to be wound out of the stator. The setting of the gap can limit the displacement of the copper wire when it is extended to the next frame, so that the winding of the copper wire can be carried out more stably and smoothly.
[0014] Preferably, the driving member is a motor, a driving rod of the motor supports the wire sheath, and the extension length of the driving rod is adjusted according to the different depths of the multiple groups of notches.
[0015] The extended length of the driving rod determines the sliding height of the wire sheath, and the sliding distance of the wire sheath determines the sliding distance of the copper wire. The sliding distance of the wire sheath is adjusted according to the depth of the gap, thereby pushing the copper wire to the bottom of the gap and making maximum use of the depth characteristics of the gap.
[0016] Preferably, a limiting portion is further provided on the inner periphery of the wire protection sleeve, and when the limiting portion slides to abut against the bottom wall of the stator outer ring, a gap is left between the top wall of the wire protection sleeve and the clamp.
[0017] When the wire sheath slides up until the limiting portion abuts the bottom wall of the stator outer ring, a distance is left between the wire sheath and the clamp. The setting of the limiting portion can structurally limit the collision between the wire sheath and the stator clamp, which is beneficial to protecting the wire sheath and the clamp.
[0018] The restricting portion is annular.
[0019] Preferably, the shapes of the multiple groups of notches are different.
[0020] The different shapes of the notches make the skeleton easier to distinguish.
[0021] Preferably, a limiting groove is provided at one end of the notch away from the opening thereof, the shape of the limiting groove being adapted to the copper wire, the limiting groove being an arc-shaped groove, and the arc angle of the limiting groove being greater than 180°.
[0022] For a notch with a larger depth, the copper wire is likely to slide down. The setting of the limiting groove can clamp the copper wire, making it less likely to slide down, which is beneficial to further improve the stability of the copper wire fixation.
[0023] Preferably, some of the notches are provided with guide surfaces, and the guide surfaces extend from the opening ends of the notches toward the limiting grooves.
[0024] When the copper wire slides upward, it can slide along the guide surface into the limiting groove, making it easier for the copper wire to be clamped in the limiting groove.
[0025] In summary, the present invention has the following beneficial technical effects:
[0026] During stator processing, after the copper wire is wound on one frame, the wire hooking device will hook the copper wire out of the stator, and at the same time, the clamp will be rotated so that the next frame that needs to be wound is rotated to a position opposite to the wire hooking device. Then the wire hooking assembly will wind the copper wire back into the stator. At this time, the copper wire between the two frames will be wound onto the outer wall of the outer ring, and then the wire hooking device will retreat to complete the winding action on the outer periphery of the outer ring. At this time, the wire guard mechanism is started, so that the wire guard moves upward toward the direction close to the stator until the wire guard is connected to the outer periphery of the stator. During the upward movement of the wire guard, the top wall of the wire guard abuts against the copper wire on the outer periphery of the stator, thereby pushing the copper wire upward. The driving part drives the wire guard to slide up a certain stroke. For the same copper wire, the upward sliding stroke of the wire guard is the same; for different copper wires, the upward sliding stroke of the wire guard is different. The different upward sliding strokes make there be height differences between multiple copper wires to avoid mutual abutment and conduction, which is beneficial to improve the stability of the copper wire and the stator after winding assembly.

[0031] The following is combined with Figure 1-3 The utility model is described in further detail.
[0032] The embodiment of the utility model discloses a stator winding machine wire protection sleeve mechanism used for matching with a stator.
[0033] Reference Figure 1 A stator winding machine wire sheath mechanism for cooperating with a stator is arranged below a fixture 2 that clamps the stator 1. The fixture 2 can rotate relative to the wire sheath mechanism. It is characterized in that it includes a wire sheath 3 and a driving member 4. The wire sheath 3 is annular. The driving member 4 drives the wire sheath 3 to approach the stator 1 and be sleeved on the outer periphery of the stator 1. When the wire sheath 3 is sleeved on the outer periphery of the stator 1, the top wall of the wire sheath 3 abuts against the copper wire on the outer periphery of the outer ring 11 of the stator 1.
[0034] During stator 1 processing, after the copper wire is wound around one frame 12, it is hooked out of the stator 1 by the wire hooking device. At the same time, the clamp 2 is rotated so that the next frame 12 to be wound is rotated to a position directly opposite the wire hooking device. The wire hooking assembly then winds the copper wire back into the stator 1. At this time, the copper wire between the two frames 12 is wound around the outer wall of the outer ring 11. The wire hooking device then retreats to complete the winding action around the outer ring 11. At this time, the wire sheath mechanism is activated, causing the wire sheath 3 to move upward toward the stator 1 until it is connected to the outer periphery of the stator 1. During the upward movement of the wire sheath 3, the top wall of the wire sheath 3 contacts the copper wire on the outer periphery of the stator 1, thereby pushing the copper wire upward. The driving member 4 drives the wire sheath 3 to slide up a certain stroke. For the same copper wire, the sliding stroke of the wire sheath 3 is the same; for different copper wires, the sliding stroke of the wire sheath 3 is different. The different sliding strokes create height differences between the multiple copper wires to avoid mutual abutment and conduction, which is beneficial to improving the stability of the copper wire and the stator 1 after winding and assembly.
[0035] Reference Figure 2as well as Figure 3 In this embodiment, the distance between the copper wire first wound on the stator 1 and the end of the stator 1 close to the wire sheath 3 is the largest, the distance between the copper wire last wound on the stator 1 and the end of the stator 1 close to the wire sheath 3 is the smallest, and the distances between the intermediate copper wires and the end of the stator 1 decrease step by step in the order of winding.
[0036] By successively lowering the height of the copper wires on the outer periphery of the outer ring 11, it is avoided that the overlapping parts of adjacent copper wires rub against or become entangled with each other when being pushed up, so that multiple copper wires can be raised in an orderly manner and the situation of abutting conduction is avoided.
[0037] Reference Figure 2 as well as Figure 3 In this embodiment, the stator 1 matched with the wire protection sleeve mechanism includes an outer ring 11 and multiple frames 12. The bottom wall of the outer ring 11 is provided with multiple groups of notches 13. The notches 13 are arranged corresponding to the multiple frames 12. The notches 13 of the multiple frames 12 wound in the same copper wire belong to the same group, and the depths of the multiple groups of notches 13 are different.
[0038] After winding the wire on each frame 12, one end of the copper wire needs to be wound out of the stator 1. The setting of the notch 13 can limit the displacement of the copper wire when it is extended to the next frame 12, so that the winding of the copper wire can be carried out more stably and smoothly.
[0039] Reference Figure 2 as well as Figure 3 In this embodiment, the driving member 4 is a motor, the driving rod of the motor supports the wire sheath 3, and the extension length of the driving rod is adjusted according to the different depths of the multiple groups of notches 13.
[0040] The extended length of the driving rod determines the sliding height of the wire guard 3, and the sliding distance of the wire guard 3 determines the sliding distance of the copper wire. The sliding distance of the wire guard 3 is adjusted according to the depth of the notch 13, thereby pushing the copper wire to the bottom of the notch 13 and making maximum use of the depth characteristics of the notch 13.
[0041] Reference Figure 2 as well as Figure 3 In this embodiment, a limiting portion 31 is further provided on the inner periphery of the wire sheath 3 . When the limiting portion 31 slides to abut against the bottom wall of the outer ring 11 of the stator 1 , a gap is left between the top wall of the wire sheath 3 and the clamp 2 .
[0042] When the wire sheath 3 slides up until the limiting portion 31 abuts against the bottom wall of the outer ring 11 of the stator 1, a distance is left between the wire sheath 3 and the clamp 2. The setting of the limiting portion 31 can structurally limit the collision between the wire sheath 3 and the stator 1 clamp 2, which is beneficial to protecting the wire sheath 3 and the clamp 2.
[0043] The restriction portion 31 is annular.
[0044] Reference Figure 2 as well as Figure 3 In this embodiment, the shapes of the multiple groups of notches 13 are different.
[0045] The notches 13 of different shapes make the skeleton 12 easier to distinguish.
[0046] Reference Figure 2 as well as Figure 3 In this embodiment, a limiting groove 14 is provided at one end of the notch 13 away from its own opening. The shape of the limiting groove 14 is adapted to the copper wire. The limiting groove 14 is an arc-shaped groove, and the arc angle of the limiting groove 14 is greater than 180°.
[0047] For the notch 13 with a larger depth, the copper wire may inevitably slide down. The setting of the limiting groove 14 can clamp the copper wire, making it less likely to slide down, which is beneficial to further improve the stability of the copper wire fixation.
[0048] Reference Figure 2 as well as Figure 3 In this embodiment, a portion of the notch 13 is provided with a guide surface 15 , and the guide surface 15 extends from the open end of the notch 13 toward the limiting groove 14 .
[0049] When the copper wire slides upward, it can slide along the guide surface 15 into the limiting groove 14 , making it easier for the copper wire to be clamped in the limiting groove 14 .
[0050] 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.
