Description

Technical Field

[0001] This invention relates to the field of magnetic ring assembly technology, and in particular to a semi-automatic assembly device for a magnetic ring at the rear end of a motor. Background Technology

[0002] During operation, the internal current of a motor changes rapidly. This is especially true for high-speed motors or those using variable frequency speed control, which generate significant amounts of high-frequency electromagnetic interference (EMI). These interference signals can propagate to the outside of the motor through power lines and signal lines, interfering with surrounding electronic equipment, such as communication devices and control systems. Magnetic rings can generate high impedance to these high-frequency interference signals, converting the interference energy into heat and dissipating it, thus reducing the motor's EMI. Similarly, in areas with complex external magnetic fields, magnetic rings can reduce the interference of external magnetic fields on the motor.

[0003] In existing technologies, when assembling a motor, magnetic rings are typically fixed inside the motor housing near the end cover in a circumferential arrangement. First, workers apply glue to the sides of the magnetic rings, and then place the magnetic rings tightly into the motor housing. This method cannot guarantee that each magnetic ring is installed at the predetermined angle, resulting in a deviation between the magnetic field generated by the combined action of the installed magnetic rings and the predetermined magnetic field, reducing the anti-interference ability of the magnetic rings. Furthermore, after the magnetic rings are bonded with glue, air bubbles may form inside the glue, reducing the connection strength between the magnetic rings and the motor housing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The second electric telescopic rod moves the baffle upward, and the baffle moves the motor housing to a suitable height.

Then, the second motor is started, and the second motor drives the second fixed body to rotate.

Then, the glue pump is started, and the glue is applied to the position of the magnetic ring to be fixed on the inner wall of the motor housing through the coating plate. At the same time, the second motor drives the motor housing to rotate centrifugally. Under the action of centrifugal force, the glue can fully enter the groove of the inner wall of the magnetic housing, improving the bonding strength of the glue.

[0015] 2. The third motor drives the support plate to rotate to a position aligned with the axis of the motor housing, and the height of the support body is sufficient.

Detailed Implementation

[0025] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Please see Figures 1-7 A semi-automatic assembly device for a rear magnetic ring of a motor includes a main plate 1, and a clamping and limiting mechanism 2 for rotating and holding the motor housing is provided at the upper end of the main plate 1.

[0027] In this embodiment, the clamping and limiting mechanism 2 includes a first limiting groove 22 formed on the upper end of the main body plate 1. A first limiting body 26 is slidably disposed in the first limiting groove 22. A first electric telescopic rod 24 is fixedly connected to the upper end of the first limiting body 26. A first fixing body 25 is fixedly connected to the telescopic end of the first electric telescopic rod 24. A second slot 215 is formed at the end of the first fixing body 25. A second motor 216 is fixedly connected to the first fixing body 25 in the second slot 215. A second fixing body 28 is fixedly connected to the transmission shaft end of the second motor 216.

[0028] The second fixing body 28 has a first slot 29 on its side. A second electric telescopic rod 210 is fixedly connected to the second fixing body 28 in the first slot 29. A baffle 211 is fixedly connected to the telescopic end of the second electric telescopic rod 210. A third electric telescopic rod 212 is symmetrically connected to the side of the second fixing body 28. A connecting plate 213 is fixedly connected to the telescopic ends of the two third electric telescopic rods 212 respectively. A pad 214 is fixedly connected to the inner side of the two connecting plates 213 respectively. A pressure sensor is provided on the upper end surface of the baffle 211 and the inner side of the pad 214.

[0029] The upper end of the second fixed body 28 is fixedly connected to a fourth electric telescopic rod 217, the telescopic end of the fourth electric telescopic rod 217 is fixedly connected to a fifth electric telescopic rod 218, the telescopic end of the fifth electric telescopic rod 218 is fixedly connected to a first delivery pipe 219, the lower end of the first delivery pipe 219 is connected to a second delivery pipe 220 communicating with it, the lower side of the second delivery pipe 220 is connected to a spreading plate 221, and the upper end of the first delivery pipe 219 is connected to a glue pump.

[0030] A first motor 21 is fixedly connected to the side of the main body plate 1. A first threaded rod 23 is fixedly connected to the transmission shaft end of the first motor 21 in the first limiting groove 22. A threaded hole 27 that cooperates with the first threaded rod 23 is opened through the side of the first limiting body 26.

[0031] Specifically, the second electric telescopic rod 210 drives the baffle 211 to move upward, and the baffle 211 drives the motor housing to a suitable height. Then, the two third electric telescopic rods 212 retract simultaneously, and the two pads 214 press and fix the sides of the motor housing. Then, the second motor 216 is started, and the second motor 216 drives the second fixed body 28 to rotate. Then, the fourth electric telescopic rod 217 and the fifth electric telescopic rod 218 extend and retract, so that the coating plate 221 on the side of the second delivery pipe 220 contacts the inner wall of the motor housing.

[0032] In this embodiment, the upper end of the main plate 1 is provided with a feeding limiting mechanism 3 for storing and limiting the magnetic ring.

[0033] The material feeding limiting mechanism 3 includes two symmetrical placement slots 34 on the upper end of the main body plate 1. The main body plate 1 is fixedly connected to the two placement slots 34 respectively. The telescopic ends of the two fixed columns 31 are fixedly connected to a third fixing body 32. The end face of the third fixing body 32 is provided with a third hollow slot 33. The inner side of the third fixing body 32 is symmetrically connected to a seventh electric telescopic rod 313. The telescopic ends of the two seventh electric telescopic rods 313 are fixedly connected to a limiting plate 314 respectively.

[0034] The two fixed posts 31 each have a sixth slot 315 on their sides. The two fixed posts 31 are fixedly connected to a fourth motor 316 in the sixth slot 315. The drive shaft ends of the two fourth motors 316 are fixedly connected to a second threaded rod 317. The sides of the two second threaded rods 317 are respectively fitted with a second limiting body 318. The sides of the two second limiting bodies 318 are respectively slidably fitted with the sixth slot 315. The ends of the two second limiting bodies 318 are fixedly connected to a fourth fixing body 39.

[0035] The upper end of the fourth fixing body 39 is provided with a fifth slot 310. A third motor 311 is fixedly connected to the fourth fixing body 39 in the fifth slot 310. A support plate 312 is fixedly connected to the drive shaft end of the third motor 311. A support body 319 is fixedly connected to the upper end of the support plate 312 near one end. A fifth motor 320 is fixedly connected to the side of the support body 319. A fixing rod 35 is fixedly connected to the drive shaft end of the fifth motor 320.

[0036] The fixed rod 35 has several fourth slots 36 distributed at equal angles on its side. The fixed rod 35 is fixedly connected to a sixth electric telescopic rod 38 in each of the fourth slots 36. The telescopic ends of the sixth electric telescopic rods 38 are fixedly connected to an electromagnet 37.

[0037] Specifically, the magnetic ring is magnetically fixed by the electromagnet 37. After the magnetic ring is fixed by the electromagnets 37 on the side of the fixing rod 35, the third motor 311 starts. The third motor 311 drives the support plate 312 to rotate to a position consistent with the axis of the motor housing, and the height of the support body 319 is sufficient. At this time, several sixth electric telescopic rods 38 extend, and the fourth motor 316 drives the second threaded rod 317 to rotate. The second threaded rod 317 cooperates to drive the support plate 312 to move up and down, and drives the magnetic ring to a position that is horizontally attached to the inner wall of the motor housing.

[0038] In use, place the main body plate 1 on a horizontal surface, then place the magnetic rings in the third fixed body 32 in a certain order. Extend the two seventh electric telescopic rods 313, driving the two limiting plates 314 to support the magnetic ring assembly. During assembly, place the motor housing on the side of the second fixed body 28, retract the second electric telescopic rod 210, and the second electric telescopic rod 210 drives the baffle 211 to move upward. The baffle 211 drives the motor housing to a suitable height. Then, the two third electric telescopic rods 212 retract simultaneously, pressing the sides of the motor housing through the two pads 214. After fixing, the second motor 216 is started, which drives the second fixed body 28 to rotate. Then, the fourth electric telescopic rod 217 and the fifth electric telescopic rod 218 extend and retract, so that the coating plate 221 on the side of the second delivery pipe 220 contacts the inner wall of the motor housing. Then, the glue pump is started, and the glue is applied to the position of the magnetic ring to be fixed on the inner wall of the motor housing through the coating plate 221. At the same time as applying, the second motor 216 drives the motor housing to rotate centrifugally. Under the action of centrifugal force, the glue can fully enter the groove of the inner wall of the magnetic ring, improving the bonding strength of the glue.

[0039] Then, the fifth motor 320 drives the fixed rod 35 to rotate. When the electromagnet 37 on the side of the fixed rod 35 moves to the vertical plane and contacts the magnetic ring, the seventh electric telescopic rod 313 retracts, thereby magnetically fixing the magnetic ring through the electromagnet 37. After the electromagnets 37 on the side of the fixed rod 35 have fixed the magnetic ring, the third motor 311 starts. The third motor 311 drives the support plate 312 to rotate to a position consistent with the axis of the motor housing, and the height of the support body 319 is sufficient. At this time, several sixth electric telescopic rods 38 extend, and the fourth motor 316 drives the second threaded rod 317 to rotate. The second threaded rod 317 cooperates to drive the support plate 312 to move up and down, driving the magnetic ring to a position that is horizontally attached to the inner wall of the motor housing. This ensures that the placement angle and distance between several magnetic rings are consistent with the predetermined values, ensuring the common anti-interference ability of several magnetic rings and improving the reliability of the device.

[0040] Then, the fifth motor 320 drives the fixed rod 35 to rotate, and the rotation speed of the fixed rod 35 is the same as the rotation speed of the motor housing. Then, the first motor 21 drives the first threaded rod 23 to rotate. The first threaded rod 23 drives the first fixed body 25 to move towards the magnetic ring through the cooperation with the threaded hole 27. At this time, several sixth electric telescopic rods 38 slightly retract to prevent the magnetic ring from contacting the glue during the movement of the motor housing. After the motor housing has moved to the outer side of the magnetic ring, several sixth electric telescopic rods 38 extend, driving several magnetic rings to be fixed in the inside of the motor housing according to the predetermined position, improving the stability of the device. The magnetic ring rotates with the motor housing while being fixed, which can reduce the generation of air bubbles during the glue adhesion process and improve the connection strength between the motor housing and the magnetic ring after the glue is bonded.
