Description

Technical Field

[0001] The invention relates to the technical field of winding components, and more specifically to an AC permanent magnet servo motor with wire connection protection. Background Art

[0002] The winding in the energy-saving AC permanent magnet servo motor is one of the key components. It is mainly responsible for converting electrical energy into mechanical energy to drive the shaft. Secondly, the AC permanent magnet servo motor has excellent dynamic performance and stability, and can provide more stable and rapid performance, which helps to improve the operating reliability of the equipment and reduce the production interruption of other equipment caused by the operation failure of the AC permanent magnet servo motor, resulting in the standby energy loss of other equipment in the entire production line. Therefore, the AC permanent magnet servo motor can also achieve energy saving and cost reduction by reducing the maintenance rate. Therefore, the AC permanent magnet servo motor with a lower failure rate has a more excellent energy saving and cost reduction effect.

[0003] Among the existing published technical documents, the Chinese patent announcement number CN213072252U discloses a lead wire structure for an AC permanent magnet servo motor. This technology is fixed to the rear cover through a fan fixing plate, and a second wire hole is opened on the fan fixing plate, and the position of the second wire hole matches the position of the first wire hole; a fastener is fixed to the fan fixing plate, and the fastener is used to fix the lead wire; when the motor is assembled, the lead wire first passes through the rear cover, then passes through the fan fixing plate, and after being positioned by the fastener, it finally enters the junction box upward, and the wire hole on the fan fixing plate is sealed with sealant, so that the sealing effect of the whole machine is improved. However, this technology still has the following problems when used.

[0004] When the AC permanent magnet servo motor is in use, the wire connection point where the winding is connected will extend to the outside, thereby fixing the winding wire in a specified position. During the fixing process, the winding wire will be fixed by bending. Excessive bending will cause the winding wire to be easily damaged in the later stage. In addition, it is inconvenient to replace and repair the connection position of the winding wire. Other equipment in the entire production line also needs to be shut down for maintenance, causing other equipment to lose energy in standby mode. Therefore, it is difficult to perform protective fixation of the wire connected to the winding according to the specified bending force and the specified bending position, and it is difficult to avoid damage caused by excessive bending. The number of maintenance times is high, the maintenance cost increases, and the energy saving and cost reduction performance is poor. Therefore, an AC permanent magnet servo motor with wire connection protection is required. Summary of the invention

[0013] Technical effects and advantages of the present invention: 1. The present invention uses a constant force bending mechanism. The collar drives multiple connecting wire harnesses to bend and pull downward, and the collar begins to move and contact the inner wall of the positioning plate. At the same time, the collar drives the connecting block to pull, and the tension spring drives the linkage block to bend and stretch. The linkage block drives the sensing end of the tension sensor to stretch. When the bending tension value sensed by the tension sensor is the same as the bending tension value set by the controller, the outer wall of the collar is tied and fixed to the positioning plate with a binding belt.

The connection between the multiple connecting wire harnesses and the winding end wires is better protected, not easy to be damaged, and the maintenance cost is greatly reduced, with better energy saving and cost reduction.

[0014] 2. The present invention utilizes an angle switching mechanism, which requires applying a large rotational force to the swivel frame. Since the sleeve ring supports the support ring and the limit ring supports the rubber pressure ring, the rubber pressure ring can provide a large extrusion force on the swivel, and the swivel drives the barcode to rotate. When the barcode rotates to the lowest bending angle, the swivel frame is loosened, and the swivel is fixed under the action of the extrusion elastic force of the rubber pressure ring. In this way, the bending angle positions of multiple connecting wire harnesses are quickly determined, and they are bent and fixed at the specified angle, avoiding excessive bending of the connection between the winding end wires and the multiple connecting wire harnesses, and avoiding bending and damage to the multiple connecting wire harnesses.

[0015] 3. The present invention adopts a bending positioning mechanism. The micro motor drives the driving gear to rotate, and the driven gear drives the linkage ring to rotate. The linkage ring and the driven gear both rotate on the outer wall of the groove ring. The positioning plate causes the barcode recognition sensor to rotate. When the barcode recognition sensor recognizes the barcode value of the barcode, the micro motor is turned off by the controller, and then the angle value of the bending positioning is set on the controller. The controller starts the push block to push up, and the rotating gear drives the linkage shaft to rotate counterclockwise. The positioning plate drives the barcode recognition sensor to rotate counterclockwise. When the angle value sensed by the angle sensor is the same as the bending positioning angle value set on the controller, the positioning plate can rotate to the specified bending positioning angle position, and can protect and fix multiple connecting harnesses and winding end wires according to the specified bending position to avoid damage caused by excessive bending of multiple connecting harnesses and winding end wires, and the winding end wire connection is better protected.

[0016] According to the mutual influence of the above multiple effects, first the barcode is rotated to the lowest bending angle position, and then the winding end wire and the wire position where the multiple connecting wires are connected can be fixed in a protective manner according to the specified bending force, and then the multiple connecting wires and the winding end wires can be fixed in a protective manner according to the specified bending position. In summary, the winding end wire and the wire position where the multiple connecting wires are connected can be fixed in a protective manner according to the specified bending force and the specified bending position, avoiding damage caused by excessive bending, not easy to be damaged, greatly reducing maintenance costs, and better energy saving and cost reduction.

A gap is provided between the driving gear 25 and the linkage ring 28, and the vertical cross-section of the linkage ring 28 is circular.

[0034] The working principle of the AC permanent magnet servo motor with wire connection protection of the present invention is as follows: Step 1: When switching the angle, first use bolts to fix the mounting frame 15 on the mounting frame, and support the housing 1 through the mounting frame 15 to increase the stability of the housing 1. At the same time, the hand rotates the rotating frame 19, and the rotating frame 19 drives the rotating ring 20 to rotate. It is necessary to apply a large rotational force to the rotating frame 19. Since the sleeve ring 6 supports the support ring 16, the support ring 16 supports the limit ring 17, and the limit ring 17 supports the rubber pressure ring 18, the rubber pressure ring 18 can provide a large extrusion force on the rotating ring 20, so that the rotating ring 20 can be rotated between the limit support ring 22 and the rubber pressure ring 18. At the same time, the rotating ring 20 drives the barcode 21 to rotate. When the barcode 21 rotates to the lowest bending angle, the rotating frame 19 is loosened, so that the rotating ring 20 is fixed under the action of the extrusion elastic force of the rubber pressure ring 18, so that the bending angle position of multiple connecting harnesses 5 is determined.

[0035] Step 2: During the bending and positioning, the multiple connecting wire harnesses 5 are kept horizontally straightened, and the multiple connecting wire harnesses 5 drive the collar 6 to be horizontally straightened, and the controller 27 starts the micro motor 26, and the micro motor 26 drives the driving gear 25 to rotate, and the driving gear 25 drives the driven gear 24 to mesh and rotate, and the driven gear 24 drives the linkage ring 28 to rotate, and the linkage ring 28 and the driven gear 24 are both rotated on the outer wall of the groove ring 23. At the same time, the linkage ring 28 drives the hinge block 29 to rotate, and the hinge block 29 makes the linkage shaft 30 rotate, and the linkage shaft 30 drives the sleeve block 33 to rotate, and the sleeve block 33 drives the positioning plate 34 to rotate, and the positioning plate 34 makes the barcode recognition sensor 35 rotate, and the barcode recognition sensor 35 rotates around the outside of the collar 6. When the barcode recognition sensor 35 recognizes the barcode value of the barcode 21, the micro motor 26 is turned off by the controller 27, so that the positioning plate 34 can rotate to the position aligned with the barcode 21, so that the positioning plate 34 can move to the angle position where the multiple connecting wire harnesses 5 are bent and fixed.

[0036] Then, by setting the angle value of the bending positioning on the controller 27, the controller 27 starts the push block 38 to push up, the push block 38 drives the rack 37 to move up, the rack 37 drives the rotating gear 36 to rotate counterclockwise, the rotating gear 36 drives the linkage shaft 30 to rotate counterclockwise, the linkage shaft 30 rotates counterclockwise inside the hinge block 29, the linkage shaft 30 drives the sleeve block 33 to rotate counterclockwise, the sleeve block 33 drives the positioning plate 34 to rotate counterclockwise, and the positioning plate 34 drives the barcode recognition sensor 35 to rotate counterclockwise. In addition, the linkage shaft 30 can drive the sensing end of the angle sensor 31 to rotate, and the hinge block 29 supports the support block 32, the support block 32 supports the angle sensor 31, and the angle sensor 31 performs angle sensing on the linkage shaft 30. When the angle value sensed by the angle sensor 31 is the same as the bending positioning angle value set on the controller 27, the push block 38 is closed by the controller 27, so that the positioning plate 34 can rotate to the specified bending positioning angle position.

[0037] Step 3: When the fixed force is bent and fixed, bend and pull the collar 6 downward, and the collar 6 drives the multiple connecting harnesses 5 to bend and pull downward. The collar 6 begins to move and contact the inner wall of the positioning plate 34. At the same time, the collar 6 drives the connection block 7 to pull, and the connection block 7 drives the tension spring 8 to stretch and bend, and the tension spring 8 drives the linkage block 9 to bend and stretch, and the linkage block 9 drives the sensing end of the tension sensor 10 to stretch, and the tension sensor 10 performs bending tension sensing. When the outer wall of the collar 6 contacts the positioning plate 34, the positioning plate 34 can position the collar 6 according to the specified angle, and the bending installation position of the multiple connecting harnesses 5 can be positioned.

[0038] When the bending tension value sensed by the tension sensor 10 is the same as the bending tension value set by the controller 27, it is checked through the display screen of the controller 27. Once the values ​​are the same, the outer wall of the ring 6 is tied and fixed to the positioning plate 34 using a strap, so that the multiple connecting wire harnesses 5 on the ring 6 can be fixedly installed according to the specified bending tension. At the same time, the multiple connecting wire harnesses 5 can also be positioned and fixedly installed according to the specified bending angle, avoiding excessive bending of the multiple connecting wire harnesses 5 and bending damage to the multiple connecting wire harnesses 5. The connection between the winding end wire 2 and the multiple connecting wire harnesses 5 can be protected against excessive bending. The connection between the multiple connecting wire harnesses 5 and the winding end wire 2 is not easy to bend and damage. The winding coil 4 does not need to be frequently disassembled and replaced, is more durable, is not easy to be damaged, the maintenance cost is greatly reduced, and the energy saving and cost reduction performance is better.

[0039] Step 4. When powered on and used, after the multiple connecting wire harnesses 5 are bent and fixed, they are connected to the power-on position through the terminals 11 on the multiple connecting wire harnesses 5, and the power supply terminal 11 conducts electricity to the connecting wire harness 5, and the connecting wire harness 5 conducts electricity to the winding end wire 2, and the winding end wire 2 conducts electricity to the winding connecting wire 3, and conducts electricity to the winding coil 4 through the winding connecting wire 3. The winding coil 4 is supported by the AC iron core 12, and the winding coil 4 can drive the permanent magnet rotor 13 to rotate, and the permanent magnet rotor 13 drives the rotating shaft 14 to rotate inside the casing 1, so that the AC permanent magnet drive operation can be performed.
