Description

Technical Field

[0001] The present invention belongs to the field of motor rotor manufacturing devices, and particularly relates to a motor rotor manufacturing device. Background Art

[0002] During the manufacturing process of a motor rotor, due to the uneven quality of the material, the center of gravity of the rotor will deviate from the axis. With a small unbalanced mass, a large centrifugal force will be generated during rotation, causing vibration during the operation of the motor, accelerating the wear of the bearings, and shortening the life of the motor. For large motors used in large equipment, the dynamic balance performance of their rotors is more related to the service life of the motor and the smoothness of the output rotational force. Currently, in order to ensure the dynamic balance performance of the rotor, generally after the rotor is processed, the unbalanced points are measured by a dynamic balance detection device, and then a certain amount of weight is added or subtracted at the dynamic balance adjustment position, and the operation is repeated multiple times to make the rotor reach the dynamic balance state. However, currently, each time the dynamic balance of the rotor is adjusted, the rotor needs to be accelerated to its operating speed, the adjustment position is determined, then decelerated and stopped, and after adjustment, it is accelerated again. Repeating multiple times is required to complete the dynamic balance adjustment of the rotor. The rotors of large motors are relatively heavy, and the time required for the rotor to start and stop is relatively long, which greatly increases the time for adjusting the dynamic balance of the rotor.

The rotors of large motors are relatively heavy, and the time required for their start and stop is relatively long, which will increase the time for adjusting the dynamic balance of the rotor and reduce the production efficiency of the rotor.

When the rotating shaft 102 rotates, it can drive the rotating cylinder 101 to rotate. Due to the insufficient dynamic balance of the rotor 1 to be processed, after rotation, it will drive the U-shaped bracket 201 to reciprocate left and right on the first support plate 202.

[0026] In this embodiment, please refer to Figures 1 to 13 , the dynamic balance detection unit further includes a power assembly for driving the rotor 1 to be processed to rotate.

[0033] In this embodiment, please refer to Figures 1 to 13 , the manufacturing device further includes two moving units for driving the rotating ring 301 to move along its axis.

[0034] Start the second rotating power source 402, and through the second gear 403 and the second rack 404, the second support plate 401 can be driven to move along the first guide rail 405, thereby driving the rotating ring 301 to move along the axis of the rotor 1 to be processed, so that the guide tube 501 can be close to the rotating cylinder 101. When the gap value between the guide tube 501 and the rotating cylinder 101 is smaller than the width value of the weight block 502 along the axis of the rotating cylinder 101, the second rotating power source 402 is turned off.

A push rod 512 is fixedly installed on the slider 511. The push rod 512 passes through the limit ring 515 and contacts the end surface of the weight block 502. The push rod 512 pushes the weight block 502 to fit the end surface of the rotating cylinder 101. The through slot 514 is formed through the side wall of the guide tube 501; The second telescopic power source 513 is fixedly mounted on the guide tube 501, and the telescopic direction of the second telescopic power source 513 is perpendicular to the center line direction of the guide tube 501; The second telescopic power source 513 described herein is an electric telescopic rod; One end of the telescopic end of the second telescopic power source 513 is rotatably connected to one end of the connecting rod 516.

[0036] When it is necessary to push the weight 502, start the second telescopic power source 513, which will drive one end of the connecting rod 516 to descend, thereby driving the other end of the connecting rod 516 to extend forward and push the slider 511 to slide forward. Thus, the weight 502 can be pushed by the ejector rod 512 fixed in front of the slider 511 to fit against the rotating cylinder 101.

[0037] In this embodiment, please refer to Figures 1 to 13 , the rotor weight unit further includes a storage assembly for storing a plurality of weights 502. The storage assembly includes a storage cylinder 521, a third spring 522, a door panel 523, a chute and a through hole 525; The guide tube 501 is provided with a through hole 525 that penetrates its inner and outer walls; The bottom end surface of the storage cylinder 521 is fixedly connected to the guide tube 501. The bottom end of the storage cylinder 521 is located in the through hole 525. The storage cylinder 521 is open at both the top and bottom. The internal space of the storage cylinder 521 is connected to the inside of the guide tube 501. The center line of the storage cylinder 521 is perpendicular to the center line of the guide tube 501; The end surface of the storage cylinder 521 away from the rotating cylinder 101 is the inner rear end surface of the storage cylinder. The end surface of the limiting ring 515 that fits against the weight 502 is the front end surface of the limiting ring. The inner rear end surface of the storage cylinder and the front end surface of the limiting ring are coplanar; Two slide rails 526 are fixedly installed on the top end surface of the storage cylinder 521. The slide rails 526 are provided with chutes. The guiding direction of the chutes is perpendicular to the center line direction of the storage cylinder 521. One side of the chute penetrates the slide rail 526 along its guiding direction. The two slide rails 526 are symmetrically arranged with respect to the storage cylinder 521. The door panel 523 is located between the two slide rails 526. The two ends of the door panel 523 are respectively slidably connected to the two chutes; A plurality of the weights 502 are placed overlappingly along the center line of the storage cylinder 521, that is, a plurality of the weights 502 are arranged in a row. The third spring 522 is located above the uppermost weight 502. One end of the third spring 522 abuts against the upper end surface of the uppermost weight, and the other end of the third spring 522 abuts against the lower end surface of the door panel 523.

[0038] The weight 502 is a cuboid, and the cross-sections of the storage cylinder 521 and the guide tube 501 are both rectangular. The central line direction of the guide tube 501 is the first direction, the central line direction of the storage cylinder 521 is the second direction, and the direction perpendicular to both the first direction and the second direction is the third direction; The width value of the inner wall of the storage cylinder 521 along the first direction is equal to the width value of the weight 502 along the first direction, and the width value of the inner wall of the storage cylinder 521 along the third direction is equal to the width value of the weight 502 along the third direction; The width value of the inner wall of the guide tube 501 along the second direction is equal to the width value of the weight 502 along the second direction, and the width value of the inner wall of the guide tube 501 along the third direction is equal to the width value of the weight 502 along the third direction; By providing the third spring 522, a downward pressure can be exerted on the weight 502, thereby also preventing the lowermost weight from detaching. After the lowermost weight is pushed out by the ejector rod 512, the weights above it move downward under the action of the elastic force of the third spring 522 and come into contact with the upper wall of the ejector rod 512. When the ejector rod 512 retracts, it will retract behind the weight 502, and the weights above move to fit against the inner bottom wall of the guide tube 501 under the drive of the third spring 522, thus preparing for the next weighting.

[0039] In this embodiment, please refer to Figures 1 to 13 The rotor weighting unit further includes a heat conducting rod 527, a heating coil 528, and an avoidance groove 529; The ejector rod 512 is a hollow tube. The heat conducting rod 527 passes through the slider 511 and extends into the ejector rod 512. The end face of the heat conducting rod 527 is flush with the end face of the ejector rod 512. The heat conducting rod 527 is fixedly connected to the slider 511. The material of the heat conducting rod 527 is a heat conducting material, which can be copper, aluminum, or aluminum alloy, etc.; The heat conducting rod section on the side of the slider 511 away from the limit ring 515 is the heated section. The heating coil 528 is sleeved outside the heated section of the heat conducting rod 527. Here, the heating coil 528 is a copper spiral coil. The ejector rod 512 is made of a heat insulating material, which can be polyurethane foam, mineral wool, etc. A gap can also be provided between the ejector rod 512 and the heat conducting rod 527 to reduce the heat loss on the heat conducting rod 527; The material of the weight 502 is a heat conducting material, which can be copper, aluminum, or aluminum alloy, etc.; The surface of the storage cylinder 521 that contacts the mating surface of the weight block is the inner front end surface of the storage cylinder. An avoidance groove 529 is formed on the inner front end surface of the storage cylinder 521. The avoidance groove 529 penetrates downward along the center line of the storage cylinder 521 and communicates with the guide pipe 501. The width of the avoidance groove 529 is smaller than the width of the weight block. The bonding substance is glue, and here the glue can be thermosetting glue. The thermosetting glue has a very slow curing speed at normal temperature and will quickly cure and bond after heating. The area of the mating surface of the weight block that coincides with the avoidance groove 529 is coated with glue. Due to the existence of the avoidance groove 529, the glue will not be wiped off by the inner wall of the storage cylinder 521 when applied to the mating surface of the weight block.

[0040] When the slider 511 slides, it drives the front end surfaces of the ejector rod 512 and the heat conducting rod 527 to contact the weight block 502. When the slider 511 continues to move, the weight block 502 can be moved along the guide pipe 501 and the weight block 502 can be made to fit the rotating cylinder 101. Then, when the heating coil 528 is started, the heated section can be heated, so that the temperature of the front end surface of the heat conducting rod 527 rises. Since the front end surface of the heat conducting rod 527 contacts the weight block 502, the mating surface of the weight block can be heated, so that the glue on the mating surface of the weight block cures, realizing the fixation of the weight block 502.

[0041] In this embodiment, please refer to Figures 1 to 13 , the rotor weighting unit further includes a first telescopic power source 6; The first telescopic power source 6 is fixedly installed on the rotating ring 301. The telescopic end of the first telescopic power source 6 is fixedly connected to the guide pipe 501. The telescopic direction of the first telescopic power source 6 is perpendicular to the axis of the rotor 1 to be processed. The axis of the telescopic rod of the first telescopic power source 6 intersects the axis of the rotor 1 to be processed.

[0042] Here, the first telescopic power source 6 is an electric telescopic rod.

[0043] The first telescopic power source 6 can drive the guide pipe 501 to move to different positions of the rotating cylinder 101, so that different positions can be weighted.
