Technical Field

[0001] The utility model relates to the technical field of motor coil assembly, in particular to a tool for motor coil assembly. Background Art

[0002] The coil is one of the core components of the motor and is usually used in the stator of the motor. The motor coil is a ring-shaped structure wound by a wire. When the current passes through the coil, an electromagnetic force is generated in the magnetic field, thereby realizing the drive and operation of the motor. The assembly of the motor coil is a crucial part of the motor manufacturing process. During the assembly process of the motor coil, it is necessary to ensure that the winding method, insulation layer quality, lead connection and other aspects of the coil meet the design requirements and standards. Because the quality and process of the coil directly affect the performance, efficiency and life of the motor. If the coil is poorly assembled or there is a problem, it may cause unstable operation of the motor, reduced efficiency or even damage the motor. When assembling traditional motor coils, most of them are assembled manually.

[0003] After searching, the Chinese patent application number CN217849195U discloses a tool for assembling motor coils, including a tool frame, a positioning groove for placing the motor stator is opened in the middle of the top of the tool frame, a base plate is fixed to the bottom of the tool frame, and vertical frames are fixed on the base plate before and after the positioning groove and at the rear, respectively, a pressure strip is movably connected between the two vertical frames, and an elastic clamp for gathering the coil is installed under the pressure strip.

[0004] However, in actual use, it was found that since the coil is pressed and fixed by a pressure strip, downward force is required, but there is no limit device in the positioning groove to fix the outside of the motor stator, which may cause the coil to be unstable or even offset or tilted when pressed down, thereby affecting the assembly quality of the coil. Utility Model Content

[0011] In order to facilitate the pressing and moving of the boost rod, further, a movable plate is slidably connected in the movable channel, the movable plate is arranged between the bolt and the stop block, the other end of the boost rod is fixedly connected to the movable plate, and a spring is sleeved on the boost rod, and the two ends of the spring are respectively fixedly connected to the movable plate and the boost cylinder.

[0012] In order to facilitate fixing of the limit block, preferably, a connecting rod is fixedly connected to the movable plate, and the limit block is fixedly connected to the connecting rod.

[0013] Compared with the prior art, the utility model provides a tool for assembling a motor coil, which has the following beneficial effects:

[0025] Embodiment 1:

[0026] Reference Figure 1-Figure 4A tool for assembling a motor coil includes a workbench 1 with a U-shaped groove. A pressure strip for pressing and fixing the motor coil is also provided on the workbench 1. The U-shaped groove can place the motor stator in the groove, and then the two ends of the pressure strip are respectively embedded in the channels of the motor stator, and then the pressure strip is pressed downward to press the coil. Referring to the patent publication number: CN217849195U, this is the prior art.

[0027] In order to facilitate the change of the position of the motor stator on the U-shaped groove, a groove is provided on the inner wall of the U-shaped groove, and a rotating shaft is rotatably connected in the groove, and a roller 2 is fixedly connected to the rotating shaft. The outside of the motor stator will contact the roller 2. When the coil slot in the motor stator is assembled, the outside of the motor stator can be rotated. During this process, the roller 2 will improve the adjustment convenience of the motor stator, making it faster and more convenient for workers to use it.

[0028] In addition, please refer to Figure 3 As shown in the figure, a moving channel 3 is also opened on the workbench 1, and a stop block 4 is also slidably connected in the moving channel 3, and an airbag 5 is also installed on the outside of the stop block 4. The airbag 5 is made of rubber material and can be inflated by transporting gas into the airbag 5.

[0029] A bolt 6 is also threadedly connected to the workbench 1 , and one end of the bolt 6 extends into the moving channel 3 , and a rotating disk 601 is fixedly connected to the other end of the bolt 6 , and a handle 602 is rotatably connected to the rotating disk 601 .

[0030] A return spring 401 is arranged in the moving channel 3 , and two ends of the return spring 401 are fixedly connected to the inner wall of the moving channel 3 and the stop block 4 respectively, and can be used to limit the position of the stop block 4 .

[0031] Here, when it is necessary to assemble the coil in the coil slot on the motor stator, the hand can be placed on the handle 602, and then the handle 602 is used to drive the rotating disk 601 to rotate, so that it rotates the bolt 6 clockwise. At this time, the bolt 6 will move into the moving channel 3, and can be abutted against the block 4, so that the block 4 is abutted against the outer wall of the motor stator and limited, so that the outside of the motor can be fixed, thereby improving the stability of the coil when it is pressed down, effectively avoiding the displacement or misalignment of the coil during the assembly process, and improving the assembly quality of the coil.

[0032] When the handle 602 drives the rotating disk 601 to rotate so as to rotate the bolt 6 counterclockwise, the bolt 6 will move outward from the moving channel 3 and the bolt 6 cannot abut against the stop block 4 .

[0033] Embodiment 2:

[0034] Reference Figure 1-Figure 4 A boosting cylinder 7 is also fixedly installed in the moving channel 3, and a boosting rod 701 is slidably connected to the boosting cylinder 7. A piston is arranged at one end of the boosting rod 701, and the piston fits against the inner wall of the boosting cylinder 7. The boosting cylinder 7 is connected to the airbag 5. By pushing the boosting rod 701, the piston on the boosting rod 701 can transport the gas in the boosting cylinder 7 to the airbag 5, so that the airbag 5 can expand.

[0035] In addition, a movable plate 301 is slidably connected in the movable channel 3, and the movable plate 301 is arranged between the bolt 6 and the stop block 4. The other end of the boost rod 701 is fixedly connected to the movable plate 301. A spring is sleeved on the boost rod 701, and the two ends of the spring are respectively fixedly connected to the movable plate 301 and the boost cylinder 7. The boost rod 701 can be limited by the spring.

[0036] A connecting rod 302 is fixedly connected to the movable plate 301 , and the limit block 8 is fixedly connected to the connecting rod 302 . The end of the limit block 8 is tapered and can be inserted into the gap between the roller 2 and the groove, and then fit with the outer wall of the roller 2 .

[0037] Here, when the handle 602 is used to drive the rotating disk 601 to rotate, so that it rotates the bolt 6 clockwise, the bolt 6 will move into the moving channel 3 and can abut against the block 4, thereby making the block 4 abut against the outer wall of the motor stator and limit it.

[0038] During this process, the bolt 6 will first push the movable plate 301 to move toward the position of the stop block 4, and the movable plate 301 will push the boost rod 701 to transport the gas in the boost cylinder 7 to the airbag 5, and the airbag 5 will expand. Through the airbag 5, the contact between the stop block 4 and the outer wall of the motor stator can be made more uniform and tight, ensuring that the stop block 4 and the outer wall of the motor stator are completely against and firmly fixed, reducing the shaking of the motor stator, and through the movement of the movable plate 301, the limit block 8 can be inserted into the gap between the roller 2 and the groove to limit the roller 2 and prevent it from rotating, thereby cooperating with the stop block 4 to firmly fix the outside of the motor stator.
