Description

Technical Field

[0001] The invention relates to the technical field of motor design, in particular to a dynamic balancing machine for calibrating a micro motor rotor. Background Art

[0002] The micromotor rotor is an important component of the micromotor. It is the main body of the rotating part of the motor and is usually composed of one or more coils wound around the rotor core. When current passes through the windings on the rotor, according to the principle of electromagnetic induction, the rotor rotates in the magnetic field generated by the stator (another electromagnetic component), thereby achieving mechanical movement.

[0003] The dynamic balancing machine for micromotor rotor correction is a precision detection and correction equipment. It simulates the rotation state of the rotor, measures the mass and position of the rotor imbalance under static or dynamic conditions, and then provides a correction plan to ensure that the rotor can remain balanced during operation. The core function of this equipment is to ensure that the rotor can remain balanced during rotation, thereby reducing vibration and noise and improving the operating efficiency and life of the motor.

[0004] There are still many inconveniences in the use of current equipment. When the belt drives the rotor to rotate, the belt will naturally stretch due to thermal expansion or long-term use over time, and its resilience will decrease, which will lead to a decrease in belt tension. Improper belt tension will lead to reduced transmission efficiency because the friction between the belt and the pulley is insufficient and power cannot be effectively transmitted. In addition, rotors of different sizes require different belt tensions, and fixed belt tensions will cause the dynamic balancing machine to be non-universal. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] refer to Figures 1 to 9 A dynamic balancing machine for micromotor rotor correction according to a preferred embodiment of the present invention will be described in detail below. A dynamic balancing machine for micromotor rotor correction includes a workbench 1, a processing mechanism 2 for testing the dynamic balancing performance of the micromotor rotor is slidably connected to the surface of the workbench 1, an inspection mechanism 3 for checking the tension of the belt is arranged inside the processing mechanism 2, an adjustment mechanism 4 for adjusting the tension of the belt is arranged inside the processing mechanism 2, and a positioning mechanism 5 for preventing excessive adjustment of the belt is arranged inside the processing mechanism 2; The processing mechanism 2 includes a side box 213, and the side box 213 is fixedly connected to the upper surface of the workbench 1; like Figure 3In the processing mechanism 2, a side plate 211 is placed, and the side plate 211 is slidably connected to the surface of the workbench 1. The surface of the side plate 211 is rotatably connected to the detection rotor 212. The inside of the side box 213 is rotatably connected to the side panel 214. The surface of the side panel 214 and the inside of the side box 213 are both provided with a rotating shaft 215. The surface of the rotating shaft 215 is transmission-connected with a power belt 216. The surface of the side panel 214 is fixedly connected to a motor 217. The output shaft of the motor 217 is fixedly connected to the rotating shaft 215 on the surface of the side panel 214. The side panel 214 rotates and drives the power belt 216 to fit the surface of the detection rotor 212. The motor 217 drives the rotating shaft 215 to rotate when it works, thereby driving the detection rotor 212 to rotate through the power belt 216 to perform a dynamic balance check.

[0022] like Figure 5 The inspection mechanism 3 includes a pushing block 311, which is slidably connected to the inside of the side box body 213, and the inside of the pushing block 311 is slidably connected to the detection slide bar 313, and the inside of the pushing block 311 is fixedly connected to a No. 1 spring 314, and the No. 1 spring 314 is fixedly connected to the detection slide bar 313. When the side panel 214 rotates and drives the side panel 214 to fit the surface of the detection rotor 212, the telescopic rod pushes the pushing block 311 to slide up, and the detection slide bar 313 fits the surface of the power belt 216 under the drive of the pushing block 311. When the tension of the power belt 216 is too low, the pushing block 311 will give the detection slide bar 313 an upward force through the No. 1 spring 314, thereby driving the power belt 216 to slide up synchronously until the detection slide bar 313 slides to the top, thereby increasing the tension of the power belt 216 through the adjustment mechanism 4. Figure 5 The push block 311 is internally slidably connected to an adjusting slider 312, and the push block 311 is internally fixedly connected to a No. 2 spring 315, which is fixedly connected to the adjusting slider 312. When the tension of the power belt 216 is too high, the power belt 216 imposes a restriction on the detection slide bar 313, thereby preventing the detection slide bar 313 from sliding up. At this time, as the push block 311 continues to slide up, the No. 1 spring 314 is compressed under the restriction of the detection slide bar 313 imposed by the power belt 216, and as the push block 311 continues to slide up, the detection slide bar 313 and the No. 1 spring 314 are compressed. The inclined surface of the adjusting slider 312 contacts and pushes the adjusting slider 312 to slide to the right, and then contacts the adjusting mechanism 4 through the adjusting slider 312, thereby reducing the tension of the power belt 216, so that the belt tension is in a suitable range. The tension of the power belt 216 is tested before the belt is used, so as to understand the transmission effect between the power belt 216 and the detection rotor 212, and make targeted adjustments to ensure effective contact between the power belt 216 and the detection rotor 212, thereby improving transmission efficiency and reducing energy loss.

[0023] like Figure 7 The adjusting mechanism 4 includes an adjusting transverse axis 411, which is slidably connected to the inside of the side box 213, and is fixedly connected to the rotating axis 215 on the surface of the side box 213. The inside of the side box 213 is slidably connected to a retracting rod 412 and a release rod 413, and the inside of the side box 213 is fixedly connected to a No. 3 spring 418, which is fixedly connected to the retracting rod 412. The surfaces of the retracting rod 412 and the release rod 413 are fixedly connected to a limiting axis 4111 and a rebound pick 411. 0, the surfaces of the retracting rod 412 and the release rod 413 are both rotatably connected with an adjusting block 419. When the tension of the power belt 216 is insufficient, the pushing block 311 drives the detection slide bar 313 to slide up. At this time, the release rod 413 contacts the detection slide bar 313, and the detection slide bar 313 gives a thrust to the inclined surface of the release rod 413, thereby pushing the release rod 413 to slide. The release rod 413 slides to the right and drives the adjusting block 419 to extend to the inside of the tooth groove on the surface of the No. 1 gear 414, thereby pushing the No. 1 gear 414 to rotate clockwise, as shown in FIG. Figure 7 and Fig. 9 In the embodiment, the inner rotation of the side box body 213 is connected with the first gear 414 and the second gear 416, and the second gear 416 and the first gear 414 are fixedly connected with a connecting main shaft 415. The inner sliding connection of the side box body 213 is connected with a pushing gear rod 417, and one end of the pushing gear rod 417 is fixedly connected with the adjusting horizontal shaft 411. The second gear 416 is driven to rotate clockwise through the connecting main shaft 415, and the pushing gear rod 417 is driven to slide to the right, thereby driving the rotating shaft 215 on the surface of the side box body 213 to slide to the right through the adjusting horizontal shaft 411, thereby increasing the tension of the power belt 216. When the tension of the power belt 216 is too large, the adjusting slider 312 pushes the retraction rod 412 to slide to the right, and the adjustment block 419 on the surface of the retraction rod 412 drives the No. 1 gear 414 to rotate counterclockwise, thereby driving the adjustment horizontal axis 411 to slide to the left to reduce the tension of the power belt 216, and the tension of the power belt 216 is adjusted by adjusting the position of the rotating shaft 215 on the surface of the side box 213, so that the tension of the power belt 216 is within a suitable range. By maintaining a suitable belt tension, the vibration of the motor during operation can be reduced and the smoothness of operation can be improved, and the appropriate tension can reduce the friction noise between the power belt 216 and the detection rotor 212.

[0024] like Fig. 9In the embodiment, the locking mechanism 5 includes a No. 4 spring 511, which is fixedly connected to the inside of the side box 213, and a sliding cross bar 512 is slidably connected to the inside of the side box 213. The sliding cross bar 512 is fixedly connected to the No. 4 spring 511, and the sliding cross bar 512 is T-shaped. The surfaces of one end of the contraction rod 412 and the release rod 413 are fixedly connected with a power push block 513. When the contraction rod 412 or the release rod 413 slides, the position of the rotating shaft 215 on the surface of the side box 213 is adjusted, and the power push block 513 on the surface is pushed. 3 Push the sliding cross bar 512 to disengage from the inside of the tooth block on the surface of the No. 1 gear 414. At this time, the rotating shaft 215 on the surface of the side box body 213 is in an active state. When the retracting rod 412 or the releasing rod 413 slides to the left under the action of the No. 3 spring 418, the sliding cross bar 512 will rebound and re-extend to the inside of the tooth groove of the No. 1 gear 414 under the push of the No. 4 spring 511, so as to avoid the problem of continuous rotation of the No. 1 gear 414 caused by excessive belt tension, thereby causing the problem of excessive adjustment of the position of the rotating shaft 215 on the surface of the side box body 213.

[0025] The following is the entire working process and working principle of the above-mentioned embodiment: when the side panel 214 rotates and drives the side panel 214 to fit the surface of the detection rotor 212, the telescopic rod pushes the pushing block 311 to slide up, and the detection slide bar 313 is driven by the pushing block 311 to fit the surface of the power belt 216. When the tension of the power belt 216 is too low, the pushing block 311 will give the detection slide bar 313 an upward force through the No. 1 spring 314, thereby driving the power belt 216 to slide up synchronously until the detection slide bar 313 slides to the top, thereby increasing the tension of the power belt 216 through the adjustment mechanism 4. When the tension of the power belt 216 is too high, the power belt 216 imposes a restriction on the detection slide bar 313, thereby causing the detection slide bar 313 to be unable to The locking cam 314 is in a state of being pushed upward by the spring 316, and the locking cam 316 is in a state of being pushed upward by the spring 316. High transmission efficiency, reducing energy loss. When the tension of the power belt 216 is insufficient, the pushing block 311 drives the detection slide bar 313 to slide up. At this time, the release rod 413 contacts the detection slide bar 313. The detection slide bar 313 gives a thrust to the inclined surface of the release rod 413, thereby pushing the release rod 413 to slide. The release rod 413 slides to the right and drives the adjustment block 419 to extend to the inside of the tooth groove on the surface of the first gear 414, thereby pushing the first gear 414 to rotate clockwise, and drives the second gear 416 to rotate clockwise through the connecting main shaft 415, driving the push gear rod 417 to slide to the right, thereby driving the rotating shaft 215 on the surface of the side box body 213 to slide to the right through the adjusting horizontal shaft 411, thereby increasing the tension of the power belt 216. When the power belt 216 When the tension is too large, the adjusting slider 312 pushes the retracting rod 412 to slide to the right, and the adjusting block 419 on the surface of the retracting rod 412 drives the first gear 414 to rotate counterclockwise, thereby driving the adjusting horizontal axis 411 to slide to the left to reduce the tension of the power belt 216. By adjusting the position of the rotating shaft 215 on the surface of the side box 213, the tension of the power belt 216 is adjusted, so that the tension of the power belt 216 is within a suitable range. By maintaining a suitable belt tension, the vibration of the motor during operation can be reduced and the stability of operation can be improved. The appropriate tension can reduce the friction noise between the belt and the pulley. By using the adjustment mechanism 4 in conjunction with the locking mechanism 5, when the retracting rod 412 or the release rod 413 slides,When adjusting the position of the rotating shaft 215 on the surface of the side box 213, the power push block 513 on the surface pushes the sliding cross bar 512 to disengage from the inside of the tooth block on the surface of the No. 1 gear 414. At this time, the rotating shaft 215 on the surface of the side box 213 is in an active state. When the retracting rod 412 or the release rod 413 slides to the left under the action of the No. 3 spring 418, the sliding cross bar 512 will rebound and re-extend to the inside of the tooth groove of the No. 1 gear 414 under the push of the No. 4 spring 511, avoiding the problem of excessive belt tension causing the No. 1 gear 414 to continuously rotate, thereby causing the problem of excessive adjustment of the position of the rotating shaft 215 on the surface of the side box 213.
