Description

Technical Field

[0001] This utility model relates to the field of shearing device technology, and more specifically to a stator copper wire trimming device. Background Technology

[0002] The stator is usually fixed in the motor housing. It mainly consists of an iron core, windings and a base. When current is applied to the motor, the rotating magnetic field inside the housing changes accordingly to drive the rotor to rotate.

[0003] The stator winding is made of copper wire as the main material. However, after winding, the ends of the copper wire may be damaged or of varying lengths, which will affect the subsequent processes. If it is not trimmed and smoothed, it will lead to abnormal inductance parameters or increased resistance, which in turn will cause torque pulsation or low efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies and to solve the problem of needing to trim the ends of the stator copper wire after winding.

[0005] To achieve the above objectives, this utility model can be implemented through the following technical solution: a stator copper wire trimming device, comprising a stator body, and further comprising:

[0006] A base frame, on which transmission components are mounted;

[0007] An angle intermittent adjustment unit is disposed on the base frame. The angle intermittent adjustment unit includes a clamping frame and a turntable disposed at the output end of the transmission component. A lever is disposed on the turntable.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0027] like Figure 1-4 As shown, a stator copper wire trimming device includes a stator body 5, and further includes:

[0028] Base frame 1, on which transmission component 2 is installed;

[0029] Angle intermittent adjustment unit 3 is mounted on the base frame 1. The angle intermittent adjustment unit 3 includes a clamping frame 34 and a turntable 32 mounted on the output end of the transmission component 2. A lever 33 is mounted on the turntable 32. A top rod 341 that abuts against the lever 33 is arranged in a circular array on the clamping frame 34. The stator body 5 is snapped onto the clamping frame 34.

[0030] The reciprocating translation unit 4 is mounted on the base frame 1 and includes a trimming cylinder 44. The transmission component 2 controls the output end of the trimming cylinder 44 to move closer to or further away from the stator body 5.

[0031] Specifically, during the processing of the stator body 5, copper wire needs to be wound to form a uniformly distributed annular winding. The stator body 5 is not shown in the figure. When the copper wire is wound onto the stator body 5, the stator body 5 can be fixed onto the clamping frame 34. At this time, the transmission component 2 controls the turntable 32 to rotate, so as to push the push rod 341 through the lever 33, controlling the rotating frame and the stator body 5 to rotate synchronously and adjust the angle so that the end of the copper wire on the stator body 5 is aligned with the trimming cylinder 44. At the same time, as the transmission component 2 rotates, the trimming cylinder 44 will gradually move closer to the end of the stator body 5. The cylinder then cuts the copper wire terminal near the copper wire end, thereby improving the flatness of the copper wire end and ensuring that the extension distance of each copper wire remains within the qualified range. Furthermore, the push rod 341 is evenly distributed in multiple groups along the central axis of the clamping frame 34, with the number of push rods 341 being the same as the number of windings. Whenever the turntable 32 rotates once, the clamping frame 34 rotates at a certain angle. Similarly, during the rotation of the turntable 32, the trimming cylinder 44 performs extension and retraction movements.

[0032] As a further embodiment of this utility model, the turntable 32 is provided with a support plate 31 that abuts against the top rod 341. The support plate 31 has a notch, and the lever 33 is provided on one side of the notch. When the turntable 32 rotates, the support plate 31 abuts against the two top rods 341 when the stator body 5 is not adjusted, so as to restrict the rotation of the clamping frame 34. When the notch rotates to the top rod 341, the lever 33 will contact the top rod 341 in advance to push the top rod 341 to make the clamping frame 34 rotate for angle adjustment. Then the support plate 31 continues to support the stator body 5.

[0033] As a further embodiment of this utility model, the clamping frame 34 includes a support plate 342, a locking block 343, and a support ring 345. The support plate 342 is fixed to the bottom of the support ring 345 by the locking block 343. The support ring 345 is rotatably connected to the base frame 1. The locking block 343 is provided with a boss 344 that abuts against the stator body 5. The boss 344 restricts the rotation of the stator body 5. The support ring 345 can rotate synchronously with the stator body 5. The push rod 341 under the support plate 342 cooperates with the lever 33 to drive the stator body 5 to rotate through the turntable 32 for angle adjustment.

[0034] As a further embodiment of this utility model, the reciprocating translation unit 4 includes a disk 41, a support frame 42, and a slider 43 disposed on the support frame 42. The trimming cylinder 44 is fixed on the slider 43, and a guide frame 46 is disposed on the slider 43. The disk 41 is rotatably connected to the support frame 42. A drive rod 47 is disposed at the eccentric part of the disk 41. The drive rod 47 cooperates with the guide frame 46. When the disk 41 rotates on the support frame 42, the drive rod 47 causes the slider 43 to reciprocate on the support frame 42 through the guide frame 46, thereby causing the trimming cylinder 44 to move closer to or away from the stator body 5, thereby trimming the copper wires on the stator body 5.

[0035] As a further embodiment of this utility model, the disk 41 has eccentric holes 411 arranged in a linear array, and the drive rod 47 is engaged with the eccentric holes 411, such as... Figure 2 As shown, multiple sets are evenly spaced from left to right, which allows the position of the drive rod 47 to be adjusted, thereby adjusting the sliding distance and frequency of the trimming cylinder 44 so that the trimming cylinder 44 can be adapted to the angle adjustment of the clamping frame 34.

[0036] As a further embodiment of this utility model, a cutting blade 45 is snapped onto the trimming cylinder 44. The cutting blade 45 is detachably mounted on the output end of the trimming cylinder 44. After trimming for a period of time, the cutting blade 45 can be removed and replaced to avoid the cutting blade 45 developing a notch that affects the trimming effect of the copper wire.

[0037] As a further embodiment of this utility model, the transmission component 2 includes a motor 21 and a transmission rod 22 disposed at the output end of the motor 21. The transmission rod 22 is engaged with one end of the turntable 32, and the other end of the turntable 32 is engaged with a connecting rod 24 that cooperates with the reciprocating translation unit 4. The motor 21 is fixed on the base frame 1. The model of the motor 21 can be: MHMF042L1U4-1116. The motor 21 serves as a power source to control the rotation of the turntable 32 through the transmission rod 22, thereby causing the clamping frame 34 to adjust the angle of the stator body 5 in conjunction with the stator body 5. At the same time, the connecting rod 24 connects to the disc 41 to control the trimming cylinder 44 to perform reciprocating translational motion.

[0038] As a further embodiment of this utility model, a support seat 23 is provided on the base frame 1. The support seat 23 cooperates with the transmission rod 22, and the support seat 23 plays the role of supporting the transmission rod 22, thereby improving the rotation accuracy of the transmission rod 22.

[0039] As a further embodiment of this utility model, a bracket 13 is provided on the base frame 1, and a proximity sensor 12 facing the stator body 5 is provided on the bracket 13. The model of the proximity sensor 12 can be: BCS MO8T4E2-PSM15C-S49G. The proximity sensor 12 detects whether the stator body 5 has rotated into place during the angular rotation offset process, ensuring that the trimming cylinder 44 can be aligned with the copper wire.

[0040] As a further embodiment of this utility model, a groove 11 is provided on the base frame 1, and a bracket 13 is disposed in the groove 11. The bracket 13 is fixed to the groove 11 by bolts. When the proximity sensor 12 is assembled, the base frame 1 can slide in the groove 11 to adjust the distance between the proximity sensor 12 and the stator body 5.

[0041] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0042] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
