Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, and specifically relates to an automatic rotor wire repairing device. Background Art

[0002] As a power structure for the electric lifting of automobile windows, the performance of the window lifting motor directly affects the use effect of window opening and closing. Therefore, ensuring the quality of the window lifting motor itself is the key to improving the electric lifting of automobile windows.

[0003] At present, for the existing window lifting motors on the market, such as the automobile window lifting motor disclosed in patent CN220156348U, a motor rotating shaft is coaxially arranged inside the casing. One end of the motor rotating shaft is movably passed through the open end and the connecting opening and extends into the gearbox, and a rotor is installed at the other end of the motor rotating shaft. In addition, the rotors of most window lifting motors on the market usually have eight pins to form eight winding areas, and the armature windings are wound in the corresponding winding areas. During processing, in order to ensure the separation of the armature windings of the rotor, wire repairing treatment is required. In the existing traditional processing process, manual wire repairing is usually adopted, that is, the operator manually separates the armature winding positions of the rotor. Although the above manual wire repairing method can already meet the wire repairing processing requirements of the rotor, in the actual processing process, it is necessary to repair the wires one by one for the eight pins. Not only is the operation separation time long and the production efficiency low, but it is also easy to cause the problem of pinholes in the copper wire, affecting the performance of the armature winding. In addition, during the existing manual wire repairing process, the wire repairing distance is only judged by the operator's vision, and the wire repairing error is large, and it is easy to have the problem of inconsistent wire repairing distances.

[0004] To sum up, the wire repairing method in the manufacturing process of the existing window lifting motor rotor has the problems of low efficiency, easy damage during wire repairing, and easy inconsistency in wire repairing distances, which is not conducive to the processing and manufacturing of a large number of window lifting motor rotors.

At the same time, a pressing mechanism is arranged above the elastic buffer carrier. By placing the rotor to be wire repaired on the elastic buffer carrier and clamping it by the clamping mechanism, the wire repairing needles can contact the armature. Then, the pressing mechanism presses down the rotor and the elastic buffer carrier adapts to the stroke change, so that the armature moves relative to the wire repairing needles to achieve wire repairing treatment. Not only can a plurality of wire repairing needles simultaneously repair the eight pins synchronously, improving the working efficiency, but also the wire repairing reference is unified, preventing the problems of damage and inconsistent wire repairing distances during the wire repairing process, and meeting the processing and manufacturing of a large number of window lifting motor rotors.

[0037] Specifically, the clamping mechanism 2 for realizing the telescopic movement of the wire repair needle 24 further includes a thimble retaining ring 25. At this time, the thimble retaining ring 25 is installed at the installation hole 211 of the installation plate 21 and is located below the rotor positioning seat 22, so that the rotor placed in the placement hole 221 can enter the thimble retaining ring 25 first when moving downward. And, a displacement channel 251 penetrating in the vertical direction is provided on the thimble retaining ring 25, and the upper and lower openings of the displacement channel 251 are respectively communicated with the placement hole 221 and the installation hole 211, so that the displacement channel 251 of the thimble retaining ring 25 can be used as a channel for the rotor to move downward during wire repair. At the same time, a number of needle holes 252 corresponding to the wire repair needles 24 one by one are provided on the side wall of the thimble retaining ring 25, and each needle hole 252 is communicated with the displacement channel 251. The needle tips of a number of wire repair needles 24 are inserted into the corresponding needle holes 252, so that the wire repair needles 24 can extend into or withdraw from the displacement channel 251 through the corresponding needle holes 252, so as to meet the requirement that the wire repair needles 24 contact the armature of the rotor passing through the displacement channel 251, thus meeting the wire repair requirements. In addition, the highest position of the jacking column 32 can also be limited by the thimble retaining ring 25, preventing the jacking column 32 from disengaging from the barrel inner cavity of the guide sleeve 31, and can also be used as a limiting structure when the wire repair needle 24 moves, providing conditions for preventing the sliding assembly 23 from extending the wire repair needle 24 into the displacement channel 251 excessively, and the safety guarantee is higher.

[0038] More specifically, the clamping mechanism 2 for driving the movement of the wire repair needle 24 further includes a die core base 26 and a cover plate 27. During installation, the die core base 26 is installed on the mounting plate 21.

And, a number of sliding grooves 261 are provided in an annular array on the die core base 26, and one end of each sliding groove 261 communicates with the avoidance hole. At this time, the number of sliding grooves 261 is the same as the number of pins of the rotor to be repaired, ensuring that each subsequent wire repair needle 24 can have a corresponding sliding component 23 to drive. In addition, a number of sliding components 23 are distributed in a one-to-one correspondence in a number of sliding grooves 261.

[0039] Figure 7 is a structural diagram of the sliding component of the clamping mechanism of a preferred embodiment of the present invention.

In addition, the sliding component 23 further includes an inclined slider 231 and a jacking inclined guide rod 232. During installation, the inclined slider 231 is slidably arranged in the corresponding sliding groove 261, so that the inclined slider 231 can move in the sliding groove 261. At the same time, the wire repair needle 24 is arranged at one end of the inclined slider 231 close to the avoidance hole, so that the wire repair needle 24 can be driven to move when the inclined slider 231 moves in the sliding groove 261. In addition, a first mating inclined surface is provided at the other end of the inclined slider 231. At the same time, the jacking inclined guide rod 232 is slidably arranged in the communication hole, so that the jacking inclined guide rod 232 can be telescoped in the communication hole, and a second mating inclined surface corresponding to the first mating inclined surface is provided at the top end of the jacking inclined guide rod 232. During installation, the lower end of the jacking inclined guide rod 232 extends below the mounting plate 21 and is connected with a jacking driving structure 5, that is, the jacking driving structure 5 drives the jacking inclined guide rod 232 to be telescoped in the communication hole, providing power for the telescopic movement of the jacking inclined guide rod 232, and when the jacking inclined guide rod 232 acts, the inclined slider 231 is pushed or pulled back through the second mating inclined surface and the first mating inclined surface, so as to drive the inclined slider 231 to move in the sliding groove 261, thereby driving the wire repair needle 24 to be telescoped to meet the wire repair requirements.

[0040] Figure 8 The structural diagram of the jacking drive structure of the clamping mechanism according to a preferred embodiment of the present utility model. As Figures 1 to 3 and Figure 8 shown, the jacking drive structure 5 that provides power for the jacking inclined guide rod 232 further includes a guide post 51, a bottom plate 52, a lifting plate 53, and a lifting drive 54. During installation, the guide post 51 is arranged in the vertical direction and the upper end is installed at the bottom of the mounting plate 21. At the same time, the bottom plate 52 is fixedly installed at the lower end of the guide post 51, realizing the fixation of the bottom plate 52 relative to the mounting plate 21. Moreover, the lifting plate 53 is arranged between the mounting plate 21 and the bottom plate 52 and slides on the guide post 51, enabling the lifting plate 53 to lift between the mounting plate 21 and the bottom plate 52 and being guided by the guide post 51 to maintain the stability of the lifting plate 53 during the lifting process. In addition, the lifting drive 54 is installed on the bottom plate 52 and the lifting shaft is connected to the lifting plate 53, enabling the lifting drive 54 to drive the lifting plate 53 to lift. And, the lower ends of a plurality of jacking inclined guide rods 232 are all installed on the lifting plate 53, that is, the lifting plate 53 provides a unified installation carrier for a plurality of jacking inclined guide rods 232, enabling a single lifting drive 54 to drive a plurality of jacking inclined guide rods 232 to synchronously expand and contract, thereby ensuring the processing requirements for the synchronous movement of a plurality of wire repair needles 24 and providing conditions for realizing the synchronous wire repair of multiple leads.

[0041] More specifically, the jacking drive structure 5 further includes an intermediate plate 55. At this time, the intermediate plate 55 is arranged between the bottom plate 52 and the lifting plate 53 and serves as a transfer structure between the lifting plate 53 and the lifting drive 54 in the future. At this time, a yielding hole 531 corresponding to the elastic buffer carrier 3 is opened on the lifting plate 53, enabling the lifting plate 53 to avoid the elastic buffer platform through the yielding hole 531 when moving upward, preventing the lifting plate 53 from colliding with the elastic buffer platform. In addition, one side of the intermediate plate 55 is connected to the lifting plate 53, and the other side of the intermediate plate 55 is connected to the lifting shaft of the lifting drive 54, enabling the intermediate plate 55 to connect the lifting plate 53 and the lifting shaft of the lifting drive 54 into a whole, thereby shortening the telescopic stroke of the lifting shaft of the lifting drive 54 and being conducive to the miniaturization of the lifting drive 54. And, a guide and limit rod 56 is arranged between the intermediate plate 55 and the bottom plate 52, which can not only limit the displacement stroke of the intermediate plate 55 but also guide the movement of the intermediate plate 55 to maintain the movement stability of the intermediate plate 55, and the structural design is more reasonable.

[0042] More specifically, a buffer assembly 28 is provided between the sliding assembly 23 and the corresponding trimming needle 24. The buffer assembly 28 can realize the floating arrangement of the trimming needle 24, thereby preventing the needle head of the trimming needle 24 from accidentally contacting the armature and piercing the copper wire, thereby causing a pinhole 252 to appear on the copper wire, thereby avoiding the problem of damage to the rotor during trimming. At this time, the buffer assembly 28 includes a buffer sleeve 281, a buffer shaft 282, a limit block 283 and a buffer spring 284. During installation, the buffer sleeve 281 is installed on the side of the sliding assembly 23 close to the rotor positioning seat 22, and one end of the buffer shaft 282 is slid into the buffer sleeve 281 and extends to the outside of the buffer sleeve 281 toward the side away from the rotor positioning seat 22, so that the buffer shaft 282 is slidably arranged in the buffer sleeve 281. At the same time, the end of the buffer shaft 282 can extend to the outside of the buffer sleeve 281. At this time, a limit block 283 is provided on the end of the buffer shaft 282 extending to the outside of the buffer sleeve 281 toward the side away from the rotor positioning seat 22. The limit block 283 prevents the buffer shaft 282 from escaping from the buffer sleeve 281. Preferably, the limit block 283 is a set of screws with a gasket, the size of the gasket is larger than the size of the hole of the buffer sleeve 281, and the screw thread is tightened on the end of the buffer shaft 282. In addition, the other end of the buffer shaft 282 extends toward the side close to the rotor positioning seat 22 and is provided with a protruding mounting head, through which the thread trimming needle 24 is mounted. At the same time, a buffer spring 284 is sleeved on the end of the buffer shaft 282 extending toward the side close to the rotor positioning seat 22, with both ends of the buffer spring 284 respectively resting on the mounting head and the buffer sleeve 281, so that the buffer spring 284 can provide elastic support for the buffer shaft 282, providing conditions for the buffer shaft 282 to slide on the buffer sleeve 281.

[0043] More specifically, a rubber gasket 29 is also provided on the rotor positioning seat 22. At this time, the center hole of the rubber gasket 29 is connected to the placement hole 221, so that the upper part of the rotor positioning seat 22 is a soft structure, which facilitates the rotor to be repaired to be placed in the placement hole 221 without damage, and has better safety protection.

[0044] More specifically, a plurality of positioning holes 222 are provided on the side wall of the rotor positioning seat 22. During installation, the plurality of positioning holes 222 are connected to the placement hole 221. At the same time, positioning pins 223 are selectively inserted into the plurality of positioning holes 222, and one end of the positioning pin 223 is extended into the placement hole 221, that is, a guide structure is formed in the placement hole 221 through the positioning pin 223, so that when the rotor to be trimmed is placed into the placement hole 221, the positioning pin 223 can be inserted into the gap between the two legs to align the rotor with the trimming needle 24, thereby providing conditions for subsequent accurate trimming.

[0045] More specifically, a limiting hole 311 arranged along its axial direction is further formed in the side wall of the guide sleeve 31. At this time, one side of the limiting hole 311 communicates with the barrel inner cavity of the guide sleeve 31. Meanwhile, a protruding limiting column 321 is arranged on the side wall of the jacking column 32, and the limiting column 321 is inserted into the limiting hole 311. When the rotor moves downward and presses the jacking column 32, the jacking column 32 can drive the limiting column 321 to move downward. The movement of the limiting column 321 in the limiting hole 311 is used to guide the downward movement of the jacking column 32, maintaining the stability of the jacking column 32 during downward movement, and avoiding the problem of circumferential deviation between the rotor and the wire repair needle 24 caused by circumferential rotation of the jacking column 32, thereby maintaining the consistency of the wire repair distance.

[0046] More specifically, a fixing ring 34 is sleeved on the outer wall of the guide sleeve 31 and located at its lower end. A limiting screw 341 arranged vertically upward is installed on the fixing ring 34, and the limiting screw 341 is located below the limiting hole 311. During the buffering process, when the jacking column 32 is pressed downward, the limiting column 321 can contact the limiting screw 341, thereby preventing the problem of structural damage caused by excessive downward pressure. At the same time, the downward pressing stroke of the jacking column 32 can be controlled by adjusting the position of the limiting screw 341 to meet the processing requirements of products with different lengths.
