Technical Field

[0001] This utility model relates to the field of hook commutator welding technology, specifically a welding auxiliary device for hook commutator production. Background Technology

[0002] Hook commutators are key components in DC permanent magnet series motors and single-phase series motors. They are typically composed of a bakelite powder matrix and commutation copper sheets arranged circumferentially on its outer circumference. When current flows through the motor coils during use, a rotational force is generated under the action of the magnetic field.

[0003] Currently, hook-type commutators require welding during production to achieve a reliable electrical connection between the coil and the commutator segments, ensuring stable current conduction during motor operation. During welding, the commutator needs support, but most support devices have a fixed height, and the center point of commutators of different sizes varies, making it inconvenient to process commutators of different sizes. Furthermore, welding generates harmful gases, which can negatively impact the processing environment. To address these issues, the inventor proposes a welding auxiliary device for hook-type commutator production. Utility Model Content

Rollers can be detachably installed on the upper surface of the two mounting plates and the lower surface of the moving frame, and the outer surface of the rollers is in contact with the outer surface of the steering gear. Two moving tables are slidably installed in the middle of the upper surface of the processing table. Sealing covers can be detachably installed on the sides of the two moving tables that are close to each other. Mounting screws are threaded on the upper and lower surfaces of the two moving tables that are close to each other, and the threads of the two mounting screws on the same side that are close to each other pass through the sealing cover and are threaded into the inside of the moving table.

[0006] Preferably, clamping plates are slidably installed on both sides of the upper surface of the two mounting plates and both sides of the lower surface of the movable frame, and the sides of the two opposing clamping plates that are close to each other are in active contact with the two ends of the rotating roller.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a welding auxiliary device for the production of hook-type commutators, including a processing table 1. Two mounting plates 11 are slidably installed on one side of the upper surface of the processing table 1. A support frame 2 is fixedly installed on the side of the upper surface of the processing table 1 near the mounting plates 11 for mounting a movable frame 21. The movable frame 21 is slidably installed inside the support frame 2. Rollers 13 are detachably installed on the upper surfaces of the two mounting plates 11 and the lower surfaces of the movable frame 21 for placing and positioning the commutator, preventing the commutator from moving during processing. The outer surface of the rollers 13 is in contact with the outer surface of the commutator. Two movable platforms 3 are slidably installed in the middle of the upper surface of the processing table 1 for installing a sealing cover 32 to prevent harmful gases from drifting into the air during welding. The sealing covers 32 are detachably installed on the sides of the two movable platforms 3 that are close to each other.

[0020] A bidirectional screw 14 is rotatably mounted on one side of the processing table 1, and both ends of the bidirectional screw 14 are threadedly connected to mounting plates 11. A motor 15 is fixedly mounted on the side of the processing table 1, and the output shaft of the motor 15 is fixedly connected to the bidirectional screw 14 to drive the mounting plates 11 to move. When in use, the motor 15 is turned on to drive the bidirectional screw 14 to rotate, and the rotation of the bidirectional screw 14 drives the mounting plates 11 to move.

[0021] By adopting the above technical solution, the motor 15 can drive the mounting plate 11 to move.

[0022] Two movable platforms 3 are threaded with mounting screws 33 on their upper and lower surfaces on the side closest to each other. The ends of the two mounting screws 33 on the same side are threaded through the sealing cover 32 and threaded into the inside of the movable platform 3. This is used to install the sealing cover 32. When in use, the mounting screws 33 are screwed in so that the threads of one end of the mounting screws 33 pass through the sealing cover 32 and are threaded into the inside of the movable platform 3. At this time, the installation between the sealing cover 32 and the movable platform 3 is completed.

[0023] By adopting the above technical solution, the mounting screw 33 can be used to install the sealing cover 32.

[0024] Mounting strips 22 are slidably mounted on both sides of the top lower surface of the support frame 2. Connecting strips 23 are rotatably mounted on both sides of the mounting strips 22. The end of the connecting strip 23 away from the mounting strips 22 is rotatably connected to the movable frame 21 to drive the movable frame 21 to move. In use, the movement of the mounting strips 22 drives the connecting strips 23 to swing, and the swing of the connecting strips 23 drives the movable frame 21 to move.

[0025] By adopting the above technical solution, the mounting strip 22 can drive the movable frame 21 to move.

[0026] A double-ended screw 24 is rotatably mounted on the top of the support frame 2, and mounting strips 22 are threaded onto both ends of the double-ended screw 24. The double-ended screw 24 and the bidirectional screw 14 are driven by a synchronous pulley and a synchronous belt to move the mounting strips 22. In use, the rotation of the bidirectional screw 14 drives the double-ended screw 24 to rotate, and the rotation of the double-ended screw 24 drives the mounting strips 22 to move.

[0027] By adopting the above technical solution, the double-headed screw 24 can drive the mounting strip 22 to move.

[0028] Clamping plates 12 are slidably installed on both sides of the upper surface of the two mounting plates 11 and both sides of the lower surface of the movable frame 21. The sides of the two clamping plates 12 that are close to each other are in contact with the two ends of the rotating roller 13 to install the rotating roller 13. When in use, the installation of the rotating roller 13 is completed when the sides of the two clamping plates 12 that are close to each other are in contact with the two ends of the rotating roller 13.

[0029] By adopting the above technical solution, the clamping plate 12 can install the rotating roller 13.

[0030] Adjusting screws 16 are rotatably installed in both mounting plates 11 and the movable frame 21, and the two ends of the adjusting screws 16 have opposite threads. The outer surfaces of both ends of the adjusting screws 16 are threaded with clamps 12. In use, rotating the adjusting screws 16 will move the clamps 12.

[0031] By adopting the above technical solution, the adjusting screw 16 can drive the clamping plate 12 to move.

[0032] Welding devices 31 are fixedly installed on the upper surface of the moving table 3, and the welding heads of the two welding devices 31 pass through the sealing cover 32 at their close ends. Electric cylinders 17 are fixedly installed on both sides of the processing table 1, and the output shafts of the two electric cylinders 17 are fixedly connected to the moving table 3 at their close ends to drive the moving table 3 to move. When in use, the electric cylinders 17 are turned on to drive the moving table 3 to move.

[0033] By adopting the above technical solution, the electric cylinder 17 can drive the moving platform 3 to move.

[0034] Working principle: First, place the steering gear on the two rotating rollers 13 located below. Turn on the motor 15 to drive the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 drives the mounting plate 11 to move. The movement of the mounting plate 11 drives the two rotating rollers 13 located below to move, thereby adjusting the position of the steering gear center point.

[0035] Secondly, the rotation of the bidirectional screw 14 drives the rotation of the double-ended screw 24, which in turn drives the installation strip 22 to move. The movement of the installation strip 22 causes the connecting strip 23 to swing, which in turn causes the moving frame 21 to move. The movement of the moving frame 21 then causes the upper rotating roller 13 to move, so that the outer surface of the rotating roller 13 comes into contact with the outer surface of the steering gear, thus pressing the steering gear and preventing it from moving during the processing.

[0036] Then, the electric cylinder 17 is turned on to move the moving platform 3. The movement of the moving platform 3 moves the welding device 31 and the sealing cover 32 to weld the steering gear. At this time, the sealing cover 32 seals the weld to prevent harmful gases from drifting away, and the purification device absorbs and purifies the harmful gases.

[0037] Finally, when it is necessary to replace the rotating roller 13 and the sealing cover 32, rotate the adjusting screw 16 to move the clamping plate 12, and complete the disassembly of the rotating roller 13. This makes it easy to disassemble the rotating roller 13. Also, rotate the mounting screw 33 to unscrew the mounting screw 33, and complete the disassembly of the sealing cover 32, making it easy to replace the sealing cover 32.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
