Description

Technical Field

[0001] This utility model relates to the field of coil winding machine technology, specifically a coil winding machine. Background Technology

[0002] Coil winding machines are mechanical devices that wind linear materials onto specific workpieces. They are widely used in industrial fields such as electric motors, transformers, inductor coils, and electroacoustic devices, and undertake precision coil manufacturing tasks in high-end industries such as military, nuclear power, and new energy vehicles.

[0003] In the existing technology, coil winding machines only support single-wire winding. Double-wire winding requires step-by-step operation, which is not only inefficient but also prone to problems such as misalignment between coil layers and uneven tension, resulting in a low pass rate. Furthermore, after winding, the wires need to be cut manually, which may lead to uneven cuts or damage to the coil, resulting in low work efficiency. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] A coil winding machine, such as Figures 1-7 As shown, the system includes a base plate 1, a support plate 2 fixedly mounted on the upper surface of the base plate 1, a cylinder 3 mounted on the upper surface of the support plate 2, a bearing 4 fixedly connected to the output end of the cylinder 3, a rotating shaft 5 rotatably connected inside the bearing 4, a bearing plate 6 fixedly connected to the bottom end of the rotating shaft 5, a turntable 10 rotatably connected to the upper surface of the base plate 1 via a shaft, a rotating shaft 9 fixedly connected to the upper surface of the turntable 10, a bearing plate 8 fixedly connected to the upper surface of the rotating shaft 9, a winding block 7 fixedly mounted on the upper surface of the bearing plate 8, a slot 12 provided on the outer wall of the bearing plate 8, and a limiting mechanism provided on the bottom surface of the bearing plate 8. The limiting mechanism includes a connecting plate 11, which is fixedly mounted on the bottom surface of the winding block 7, and has two grooves 13 at one end.

[0029] Among them, bearing 4 enables the rotating shaft 5 to rotate while being stably connected to the output end of cylinder 3. Under the drive of cylinder 3, the bearing plate 6 can be tightly pressed onto the winding block 7 and then rotates with the winding block 7 to assist in the winding operation of the two wires. The model of cylinder 3 is MGP12-50Z.

[0030] A motor is mounted on the bottom surface of the base plate 1, and the output end of the motor is connected to the turntable 10. A frame 15 is fixedly mounted on the bottom surface of the connecting plate 11. A slide rod 16 is fixedly mounted inside the frame 15. Two clamping blocks 17 are sleeved on the outside of the slide rod 16, and the two clamping blocks 17 cooperate with each other. One end of each clamping block 17 has a beveled cut to allow subsequent wires to be smoothly inserted between the two clamping blocks 17. Supporting springs are sleeved on the outside of the slide rod 16 near both ends. Several anti-slip grooves are opened on the inner wall of each clamping block 17. The anti-slip grooves can increase the friction between the wire and the clamping block 17 and improve the clamping stability of the wire by the clamping block 17.

[0031] In use, place the free ends of the two wires to be wound on the upper surface of the second support plate 8 and close to one end of the connecting plate 11, and pass them around the inside of the slot 12 and respectively into the two grooves 13. Finally, pass the two free ends of the wires through the position between the two clamping blocks 17. When passing through, the two clamping blocks 17 can be driven to slide along the slide rod 16 installed in the frame 15 and move away from each other, so that the two support springs are compressed and contracted until the two free ends of the wires pass through the two clamping blocks 17 and are placed in place. Under the action of the rebound force of the support springs, the two clamping blocks 17 can be brought closer to each other to clamp and fix the free ends of the wires, so as to prevent them from separating from the second support plate 8 later and affecting the winding effect.

[0032] When the free end of the conductor is fixed on the second bearing plate 8, the first motor can drive the turntable 10 to rotate, thereby driving the second shaft 9 to rotate, which in turn drives the second bearing plate 8 and the winding block 7 to rotate. The first bearing plate 6 rotates with the winding block 7 through the first shaft 5, which can simultaneously wind the two conductors to form a double-layer coil.

[0033] Through the above operations, two wires can be wound simultaneously to form a double-layer coil. Compared with the existing method of winding wire step by step with the help of manual semi-automatic winding equipment, this method can effectively improve winding efficiency and avoid problems such as misalignment between coil layers and uneven tension caused by errors in manual step-by-step operation.

[0034] A mounting plate 21 is fixedly connected to the outer wall of the base plate 1. A shearing body 14 is movably mounted on the upper surface of the mounting plate 21. A reciprocating screw 20 is rotatably connected inside the mounting plate 21. A movable block 22 is sleeved on the outside of the reciprocating screw 20, and the upper end of the movable block 22 is fixedly connected to the shearing body 14. The inner wall of the movable block 22 and the reciprocating screw 20 is provided with a thread that matches the reciprocating screw 20. When the reciprocating screw 20 rotates, the movable block 22 can be driven to move back and forth left and right under the cooperation of the thread.

[0035] A motor is mounted on the outer wall of the mounting plate 21, and the output end of the motor is connected to one end of the reciprocating screw 20. Two connecting shafts 23 are rotatably connected to the inner wall of the shear body 14. Movable plates 18 and gears 24 are fixedly connected to the outer walls of the two connecting shafts 23, and the two gears 24 are meshed with each other. The motor model is BM2-160.

[0036] Both movable plates 18 are fixedly connected to one end of a shearing blade 19, and the two shearing blades 19 cooperate with each other. A second motor is installed on the outer wall of the shearing body 14, and the output end of the second motor is connected to one of the connecting shafts 23.

[0037] Specifically, after winding is completed, the second motor on the mounting plate 21 starts, driving the reciprocating screw 20 to rotate, which in turn moves the movable block 22, thereby moving the shearing body 14 towards the winding block 7. At the same time, the motor drives one of the connecting shafts 23 to rotate, which in turn drives two gears 24 to rotate simultaneously in opposite directions. This causes the two shearing blades 19 connected and mounted by the two movable plates 18 to open, and under the action of the shearing body 14, the two opened shearing blades 19 are positioned at the end of the coil to be cut. Similarly, the motor reverses direction at this time, which can drive the two shearing blades 19 to open. The shearing blades 19 close simultaneously, cutting the two wires at the cut points and automatically disconnecting the wires. At this time, the cylinder 3 drives the bearing 4 and the rotating shaft 5 to move upward, which in turn moves the support plate 6 upward, moving the support plate 6 away from the winding block 7. The formed coil can then be removed from the winding block 7, completing the winding of a set of coils. Through the above operations, the formed coil can be automatically cut without the need for manual cutting with tools, saving time and effort, and eliminating the possibility of damage to the cutting edge due to errors in manual operation, thus effectively improving work efficiency.

[0038] Among them, the circuits of motor 1, motor 2, cylinder 3 and motor can be controlled by an external controller to operate the start and stop. This is existing technology and will not be described in detail. The model of motor 1 and motor 2 is MR-J.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
